2015 was an unprecedented year for autism research with many significant advances that will improve the lives of people with autism. Just last week, for example, the CDC reported a 5-month decrease in the age that children are first being evaluated for autism, which means families are learning the signs, acting earlier, and, hopefully, starting early intervention services earlier. In 2015, we changed the way we think about females with autism, gained a better understanding of the underlying genetic causes of autism, and made important progress in both behavioral and medical interventions.
Day and Nighttime Excretion of 6-sulphatoxymelatonin in Adolescents and Young Adults with Autistic DisorderPublished December 8, 2015 in Psychoneuroendocrinology
Low melatonin excretion was observed in autism, both at daytime, nighttime, and during 24h collection. Nocturnal excretion of melatonin was negatively correlated with autism severity in the overall level of verbal language, imitative social play, and repetitive use of objects.

ASF, Autism Speaks and the American Academy of Pediatrics respond to U.S. Preventive Services Task Force draft recommendations on screening for ASD.Published August 3, 2015
At a time when 1 in 68 children is diagnosed with autism, early identification, diagnosis and treatment is crucial to give children the best opportunity to reach their full potential. The ambiguity of the statement offered by the US Preventative Services Task Force (USPSTF) on autism screening is troubling and unfortunately, may be easily misinterpreted. While the task force does not explicitly recommend against screening for autism, they state there is insufficient evidence to support autism-specific screening in clinical settings. Instead, they have called for more research in this area.As a result, the task force has failed to fully endorse screening despite an abundance of research that demonstrates it is effective in a variety of settings1-3, leads to earlier identification of autism4, and that this earlier identification provides opportunities for early intervention which improves the lives of children with autism5. Research has demonstrated that formal screening is more effective than relying on clinician judgement alone1,6. This is especially important in reducing racial and ethnic disparities in access to care7,8 Moreover, screening is quick, affordable and has no substantial risk. We intend to review the USPSTF report and its methodology to understand why it differs from other evidence-based recommendations from the American Academy of Pediatrics and from experts in the field of autism spectrum disorders. Every child deserves an early, accurate diagnosis and we are hopeful that after the review period the USPSTF reconsider their conclusions.

Eliminating the Aspergers label and categorizing it under Autism Spectrum Disorder was one of the most controversial changes to the DSM-5. Parents and adults with Aspergers denounced this diagnostic revision, fearing that being a member of the autism group would contribute to greater stigma. Despite these popular convictions, two recent studies tested the effect of clinical labels on peer perception and concluded no significant difference between a label of Aspergers or ASD. In fact, disclosing any clinical information from the start resulted in more positive attitudes and higher chances for treatment success.

A new study from the Kennedy Krieger Institute in Baltimore indicates that generally girls are getting diagnosed with autism at a later age than boys, perhaps because they exhibit different and less severe symptoms. The study is based on data from the Institute’s Interactive Autism Network, an online registry of almost 50,000 individuals and their families affected by autism. In the registry, age of first diagnosis was available for 9,932 children, and 5,103 had completed the Social Responsiveness Scale, which identifies the presence and severity of social impairment.

Two separate studies published last week independently add to the body of evidence showing that genes and environment, together, are important to study risk factors in autism. The first is a study looking at the risk of autism in mothers who had diabetes and the other is an analysis of epigenetic markers from dads of kids with autism. While they tackle two different angles, they have a common thread: factors or mechanisms of the combined effects of genes/environment in ASD.

Researchers have been making tremendous progress in their efforts to understand the causes of autism, as well as which interventions may be most effective to help children with the disorder thrive.This work is especially critical as the number of children in the U.S. with autism grows. Approximately 1 in 68 children in the U.S. currently has autism, an increase of nearly 30 percent in recent years — at least partly due to greater awareness and improved diagnostics.
Delays in diagnosing and treating autism often occur when doctors ignore parents’ concerns about their child’s early development, a new study suggests.A team led by Dr. Katharine Zuckerman, of Oregon Health and Science University in Portland, compared the medical records of more than 1,400 children with autism against those of 2,100 children with other forms of delayed intellectual development.

Previous studies have shown an improvement in ASD related behaviors following administration of omega-3 fatty acid supplementation which have all failed to reach statistical significance. There has also bee conflicting data on the potential therapeutic effects of omega-3 fatty acids in ASD and unanswered questions about the timing of treatment. However a recent study published in Molecular Autism utilizing a randomized controlled trial design in preschool children reported no improvements in behavior, in fact, the omega-3 treatment group showed some worsening in externalizing behaviors over the study.

Recent evidence shows a subset of individuals with autism may have difficulties breaking down a plasticizer called bisphenol A. This metabolic pathway may be applicable to other exposures as well, and needs further study. The study didnt look at what causes autism, but it did show a difference that may be helpful in understanding autism symptoms in the future.
A new paper brings together a group of autism researchers representing a range of views and diverse disciplines in order to develop a consensus statement regarding the empirical and theoretical bases of Natural Developmental Behavioral Interventions (NDBI). These are behavioral interventions that utilize applied behavioral analysis (ABA) approaches through naturalistic settings. ABA is oftentimes wrongly equated with a specific method, like discrete trial training rather than being understood as an umbrella of empirically based practices. In NDBIs, the ABA approach is presented in settings such as play and daily routines and use child directed strategies. The goal of this new paper was to describe the influences of both behavioral psychology and developmental science on the evolution of early intervention for ASD and their influence on effective, evidence-based NDBIs. The paper also evaluates various NDBIs available for young children with ASD, examining the historical context in which they have been developed, common characteristics of established, evidence-based NDBIs, and requisite features of NDBIs. Because this type of intervention has a strong research base, the demonstrated efficacy of this type of intervention needs to be shared with the research community and the public sector. It summarizes the work of many researchers, working in parallel in different locations and publishing independently on a wide range of NBDI approaches. The effectiveness of this wide range of approaches may not yet be known to parents, clinicians, physicians and funding agencies. It acknowledges a common nomenclature should be adopted rather than having differently named protocols which may confuse the public, including insurance organizations, health care providers, and parents.

Much like mapping the human genome laid the foundations for understanding the genetic basis of human health, new maps of the human epigenome may further unravel the complex links between DNA and disease. The epigenome is part of the machinery that helps direct how genes are turned off and on in different types of cells. Epigenetic markers are just beginning to be understood in Alzheimers and cancer, with more work needed in autism spectrum disorders. Now that the epigenome has been mapped in over 100 cell types, this data can be used to better understand ASD.

Transcriptome Analysis Reveals Dysregulation of Innate Immune Response Genes and Neuronal Activity-Dependent Genes in AutismPublished December 10, 2014 in Nature
Using resources from the Autism BrainNet, a new study in brains affected by autism revealed a common factor of activated immune cells. Led by Dr. Dan Arking at Johns Hopkins, the project analyzed dats collected from 72 individuals, both with and without autism The findings compared gene expression across these two groups and from different brain banks. It also utilized a large dataset that contains data on existing autism risk genes. This represents the largest dataset so far in studying gene expression in the brains of autism. Previous studies have been too small to make meaningful conclusions, because of the lack of tissue available. The team, which also included the University of Alabama at Birmingham, saw that in individuals with ASD, a type of immune cell called microglia was always active, with genes for inflammation always being turned on. Arking noted that he did not think that the inflammation itself as the root cause of autism, but that it is the marker of a downstream effect. This type of inflammation is not well understood but it highlights the lack of current understanding about how innate immunity controls neural circuits, Dr. Andrew West, associated professor of neurology at the University of Alabama at Birmingham said.

Copy number variations are known to play a role in autism spectrum disorders. In a novel approach to study CNVs that may be present in family members, scientists look at genes in multiple generations of families affected with or without ASD as well as other psychiatric disorders. In one family, a part of chromosome 11 jumped out as being important for autism and what is known as the broader autism phenotype. (This is when a person does not have a diagnosis but meets some of the criteria for ASD.) This region contains genes for mitochondrial function and detoxification, but was found in the only family where the specific mutation was passed on beyond just parent to child. This shows that the genetic risk factors are complex and not even the same within the same family.

Explaining the Increase in the Prevalence of Autism Spectrum Disorders: The Proportion Attributable to Changes in Reporting PracticesPublished November 3, 2014 in Pediatrics
The prevalence of autism spectrum disorders has increased markedly in recent decades, which researchers have suggested could be caused in part by factors such as changes in diagnosis reporting practices. This study in Pediatrics sought to quantify the degree to which changes in reporting practices might explain this increase. Danish national health registries have undergone a change in diagnostic criteria in 1994 and the inclusion of outpatient contacts to health registries in 1995, thus Danish prevalence was studied. The study found that changes in reporting practices can account for most (60%) of the increase in the observed prevalence of ASDs in children born from 1980 through 1991 in Denmark, which supports the argument that the apparent increase in ASDs in recent years is in large part attributable to changes in reporting practices.

Analyzing the sequences of more than 20,000 people, researchers have unearthed the largest and most robust list of autism genes so far, they reported in the journal Nature.These 50 high-confidence autism genes may help researchers understand the biological underpinnings of autism. The researchers found these genes by scouring the exomes, the protein-coding regions of the genome, looking for rare genetic glitches unique to people with autism.
Much of the genetic risk for autism may reside in regulatory regions of the genome, hidden from traditional methods of sequencing analysis. That’s the upshot of preliminary results from three studies presented at the 2014 American Society of Human Genetics Annual Meeting in San Diego. Together, the findings from these new studies show the promise of looking for autism risk in unusual places.
A group in the UK conducted an exhaustive literature search surrounding current studies on sex and gender differences and autism spectrum disorders. This literature search grouped studies into four categories, focusing on behavioral features, diagnosis and disparity issues, causes of disparity, and developmental trajectory. These same topics will be discussed on October 29 at the Sex and Gender Differences in ASD science workshop in New York, sponsored by the Autism Science Foundation and Autism Speaks.
About 20% of younger siblings of children with Autism Spectrum Disorder (ASD) will develop the condition by age 3. A new study by Yale School of Medicine researchers has found that 57% of these younger siblings who later develop the condition already showed symptoms at age 18 months. Published in the October Journal of the American Academy of Child & Adolescent Psychiatry, this is the first large-scale, multi-site study aimed at identifying specific social-communicative behaviors that distinguish infants with ASD from their typically and atypically developing high-risk peers as early as 18 months of age.
Mice with mutations in the autism-linked gene WDFY3 have enlarged brains reminiscent of those seen in some children with autism, finds a study published in Nature Communications. The brain overgrowth begins in the womb, the study found. WDFY3 plays a role in autophagy, a process that rids cells of damaged or unneeded parts. Mouse embryos with two copies of the mutant gene have enlarged brains and an excess of immature neurons that divide faster than usual. They also have misdirected patches of neurons. Similar changes have been observed in people with autism.

There is less myelin in the brains of people with autism than in those of controls, according to a study published in Psychological Medicine. Myelin is an insulating material that allows neurons to fire rapidly. Researchers applied a method that measures myelin in living brains with autism for the first time. The researchers speculate that low myelin explains the weak connectivity observed in the brains of people with autism. Without proper insulation, electrical signals travel slowly along the axons, making it difficult for regions of the brain to coordinate their activity.
Mothers of children with autism are significantly less likely to report taking iron supplements before and during their pregnancies than the mothers of children who are developing normally, a study by researchers with the UC Davis MIND Institute has found. Low iron intake was associated with a five-fold greater risk of autism in the child if the mother was 35 or older at the time of the child’s birth or if she suffered from metabolic conditions such as obesity hypertension or diabetes. The research is the first to examine the relationship between maternal iron intake and having a child with autism spectrum disorder.
A new study reports that by the time they turn 1, infants who are later diagnosed with autism smile less often than those who do not develop the disorder. That suggests that reduced smiling may be an early risk marker for the disorder. In the study, published in the Journal of Abnormal Child Psychology, researchers examined 22 typically developing infants with no family history of autism and 44 infant siblings of children with the disorder. These so-called baby sibs have an increased risk for autism. In the new study, half of the 44 baby sibs later developed autism. The results of this study are important because clinicians often struggle to identify those baby sibs who will later develop autism versus those who may display autism-like traits but wont develop the disorder.

In a study conducted at the medical college of Georgia, researchers found a reduction in estrogen receptors in the frontal cortex of brains of boys with ASD. They also found a decrease in the expression of an enzyme that regulates hormones in the brain. The researchers suggest that this may be one of the reasons for the sex difference in ASD, but these findings also point to a potential gene/environment interaction in the disorder. One of the drawback of this study, however, is that there were only 13 samples in each group. The reality is that there is a shortage of available brain tissue to study.

Across the country and around the world, children are getting sick and dying from preventable diseasesin part because some parents are choosing not to vaccinate their children. Alison Singer, President of the Autism Science Foundation, and Dr. Amy Middleman, Adolescent Medicine Specialist at the University of Oklahoma’s Health Sciences Center, examine the science behind vaccinations, the return of preventable diseases, and the risks of opting out. Theyre both featured in the PBS NOVA documentary VaccinesCalling The Shots, which airs September 10, at 9 pm, on PBS.
Autism Treatment in the First Year of Life: A Pilot Study of Infant Start, a Parent-Implemented Intervention for Symptomatic InfantsPublished September 9, 2014 in Journal of Autism and Developmental Disorders
A new study conducted by researchers at the University of California Davis MIND Institute and published in the Journal of Autism and Developmental Disorders suggests that very early intervention can greatly reduce symptoms of autism as children age. The study looked at a 12-week treatment program with seven infants aged 9 to 15 months; researchers followed the children until they were 3 years old. Over time, these children showed fewer symptoms of autism. Although the sample size was small and it was not a randomized study, this study indicates exciting results from this type of intervention.
Services for Children with Autism Spectrum Disorder in Three Large Urban School Districts: Perspectives of Parents and Educators.Published September 5, 2014 in Autism
Researchers from Philadelphia, LA and Rochester addresses issues that is on the mind of every parent of a child with autism: What can I expect when my child with ASD enters school? The group interviewed parents, teachers and administrators in schools and asked them what their greatest challenges were, in hopes of identifying ways to address those problems. Across all three cities and across all the different groups some common themes emerged: first, the analysis identified and documented that there was underlying tension between all the groups. Parents were frustrated with the school system and some of the systems in place. Teachers also expressed frustration with the administrators and the system in general. Also, while need for training was identified, what was surprising was that everyone thought it was needed. Teachers thought it was needed for themselves, for their teachers aids, and even the administrators wanted to get in on the action. Finally, parents, teachers and administrators felt that there needs to be a cultural shift to support the idea of inclusion, rather than exclusion.
A new technique helps researchers trace the nerve fibers that connect brain regions by revealing how the fibers physically relate to curves and folds on the brains surface. The method was described in Medical Image Analysis. The technique examines the relationship between white matter, composed of nerve fibers and support cells, and gray matter, which is largely made of the cell bodies of the neurons the fibers sprout from. Preliminary findings support the theory that autism involves early, hyperconnected and dense brain growth before an abnormal decline, the researchers say.
To characterize people who carry deletions in 16p11.2 and 15q13.3, genetic regions linked to autism, two studies published this summer looked in detail at dozens of people with either deletion. The studies found that deletions in these regions lead to diverse symptoms that only sometimes include autism. The studies were published in the journals Biological Psychiatry and Genetics in Medicine.
As a babys brain develops, there is an explosion of synapses, the connections that allow neurons to send and receive signals. But during childhood and adolescence, the brain needs to start pruning those synapses, limiting their number so different brain areas can develop specific functions and are not overloaded with stimuli.Now a new study suggests that in children with autism, something in the process goes awry, leaving an oversupply of synapses in at least some parts of the brain.
People with autism often have trouble recognizing faces, and tend to avoid looking at others’ eyes. These deficits may contribute to their difficulty picking up on social cues. An adaptation of an adult face recognition test for children will make it easier to chart the development of childrens abilities, researchers say. The new test is described in a study published in Neuropsychologia.

The configuration of methyl tags that modify DNA in sperm change as men get older, according to a study published PLOS Genetics. These alterations may help explain why children of older fathers are at increased risk for neuropsychiatric disorders such as autism. Researchers at the University of Utah collected sperm from 17 men, once in the 1990s and again in 2008. They found that the distribution of methyl tags, a particular kind of DNA modification, shows relatively consistent changes over time in the sperm. However, the study does not necessarily prove that these altered patterns survive past fertilization or influence the risk of disorders such as autism.
In a study published this week, Canadian infant sibs researchers examined very early symptoms in infants at risk for ASD. These are infants who have an older sibling affected with ASD and show a 1/5 recurrence rate. Meaning instead of 1/68, these kids have a 1/5 chance of having ASD. Because they were able to follow them over time, they assessed them carefully as they grew up. In this study, they were focused on smiling and affect. They showed that infants at risk for ASD that went on to get an ASD diagnosis didnt smile as much at 12-18 months of age. This is consistent with previous red flags of no warm joyful smiles but takes it a step farther and shows the duration and number of smiles is fewer in kids with ASD. Researchers are going to use this to improve the early signs and symptoms of autism and develop more targeted interventions for the early stages of ASD.
Mice modeling autism have trouble integrating different kinds of sensory information such as sight, sound and touch. A study published in Neuron reports that an imbalance between signals that calm neurons and those that excite them leads to these sensory problems.
A test designed to characterize natural, spontaneous language use in autism shows solid promise in its first trials in typically developing children. The results were published in the Journal of Autism and Developmental Disorders.The researchers assessed the ease of use and reliability of the test in 180 typically developing children in Michigan, ranging in age from 2 to 5 years. They confirmed that the youngest children can do the various tasks on the test and that the codes developed for the test match the skills of the oldest children. The researchers’ goal is to build a baseline of standard scores against which the scores of children with autism or other communication disorders can be compared.
At its core, autism is the same disorder worldwide. And ideally, it should be possible to identify it consistently and accurately everywhere. But most screening methods for the disorder were developed in the U.K. and U.S., and linguistic and cultural differences can affect their performance elsewhere.
ASF President Alison Singer on Good Morning America Comments on Research About Kids Moving Off the SpectrumPublished July 31, 2014 in Good Morning America
New research by Cathy Lord and Deborah Fein suggests 10% of kids with autism achieve “optimal outcome.” Autism Science Foundation President Alison Singer speaks about this new research on Good Morning America, saying there’s no miracle cure, and that we need more research so we can discover why certain children are improving so that the same opportunity for improvement can be expanded to more children.
Expansion of the Clinical Phenotype Associated with Mutations in Activity-Dependent Neuroprotective ProteinPublished July 23, 2014 in Journal of Medical Genetics
A new study has identified a genetic change in a recently identified autism-associated gene, which may provide further insight into the causes of autism. The study, now published online in the Journal of Medical Genetics, presents findings that likely represent a definitive clinical marker for some patients’ developmental disabilities. Researchers identified a genetic change in a newly recognized autism-associated gene, Activity-Dependent Neuroprotective Protein (ADNP), in a girl with developmental delay. This change in the ADNP gene helps explain the cause of developmental delay in this patient. This same genetic change in ADNP was also found in a boy who was diagnosed with autism.
A lab called Autism BrainNet is collecting brains for study. The belief is that brain tissue study is the key to solving autism. Unlike with Alzheimer’s disease, where literally thousands of brains have been studied, during the last three decades only 100 autism brains have been studied. Four to five brains are donated for research every year. The Autism BrainNet study is looking to triple that number with the hope of answering some of the most basic questions about the disorder.

A variation in the CHD8 gene has a strong likelihood of leading to a type of autism accompanied by digestive problems, a larger head and wide-set eyes, a study in Cell reports. This discovery is part of an emerging approach to studying the underlying mechanisms of autism and what those mean for people with the condition. Many research teams are trying to group subtypes of autism based on genetic profiles. This is the first time researchers have shown a definitive cause of autism from a genetic mutation.

The Senate passed a bill Thursday night that reauthorizes federal support for autism programs. The Autism CARES Act, H.R. 4631, requires the Secretary of Health and Human Services to designate an official to oversee national autism spectrum disorder (ASD) research. It also extends autism education programs through 2019. The House passed the measure by voice vote last month and the Senate agreed to it through a unanimous consent agreement. The bill now heads to President Obamas desk for his signature.

“Atypical motor behaviors are common among children with autism spectrum disorders (ASD). However, little is known about onset and functional implications of differences in early motor development among infants later diagnosed with ASD. Two prospective experiments were conducted to investigate motor skills among 6-month-olds at increased risk (high risk) for ASD (N1 = 129; N2 = 46). Infants were assessed using the Mullen Scales of Early Learning (MSEL) and during toy play. Across both experiments, high-risk infants exhibited less mature object manipulation in a highly structured (MSEL) context and reduced grasping activity in an unstructured (free-play) context than infants with no family history of ASD. Longitudinal assessments suggest that between 6 and 10 months, grasping activity increases in high-risk infants.”

Brief Report: Assessment of Early Sensory Processing in Infants at High-Risk of Autism Spectrum DisorderPublished June 27, 2014 in Journal of Autism and Developmental Disorders
“This study assessed sensory processing differences between 24-month infants at high-risk of autism spectrum disorder (ASD), each with an older sibling with ASD, and low-risk infants with no family history of ASD. Sensory processing differences were assessed using the Infant/Toddler Sensory Profile, a parent-reported measure. Groups were compared based on 3-year outcomes: (a) high-risk infants subsequently diagnosed with ASD; (b) high-risk infants without an ASD diagnosis; and (c) low-risk infants without an ASD diagnosis. Analyses showed that high-risk infants diagnosed with ASD have more difficulty with auditory processing (i.e., responses to auditory stimuli) and lower registration (i.e., lacking sensation awareness) compared to controls. Thus, behavioral responses to sensory input represent early risk markers of ASD, particularly in high-risk infants.”

OBJECTIVE:Our understanding of the influence of maternal race/ethnicity and nativity and childhood autistic disorder (AD) in African Americans/blacks, Asians, and Hispanics in the United States is limited. Phenotypic differences in the presentation of childhood AD in minority groups may indicate etiologic heterogeneity or different thresholds for diagnosis. We investigated whether the risk of developing AD and AD phenotypes differed according to maternal race/ethnicity and nativity.METHODS:Children born in Los Angeles County with a primary AD diagnosis at ages 3 to 5 years during 1998-2009 were identified and linked to 1995-2006 California birth certificates (7540 children with AD from a cohort of 1?626?354 births). We identified a subgroup of children with AD and a secondary diagnosis of mental retardation and investigated heterogeneity in language and behavior.RESULTS:We found increased risks of being diagnosed with AD overall and specifically with comorbid mental retardation in children of foreign-born mothers who were black, Central/South American, Filipino, and Vietnamese, as well as among US-born Hispanic and African American/black mothers, compared with US-born whites. Children of US African American/black and foreign-born black, foreign-born Central/South American, and US-born Hispanic mothers were at higher risk of exhibiting an AD phenotype with both severe emotional outbursts and impaired expressive language than children of US-born whites.CONCLUSIONS:Maternal race/ethnicity and nativity are associated with offspring’s AD diagnosis and severity. Future studies need to examine factors related to nativity and migration that may play a role in the etiology as well as identification and diagnosis of AD in children.

A study out of the University of California Davis found that women who live near farmland where pesticides are applied are 60 percent more likely to give birth to a child with autism or other developmental delays. In the study, the association was stronger for women exposed during their second or third trimester. The study looked at three categories of pesticides: organophosphates, pyrethroids and carbamates; all three were found to have associations with ASD or other developmental delays.
Computer Vision Tools for Low-Cost and Noninvasive Measurement of Autism-Related Behaviors in InfantsPublished June 22, 2014 in Autism Research and Treatment
“The early detection of developmental disorders is key to child outcome, allowing interventions to be initiated which promote development and improve prognosis. Research on autism spectrum disorder (ASD) suggests that behavioral signs can be observed late in the first year of life. Many of these studies involve extensive frame-by-frame video observation and analysis of a child’s natural behavior. Although nonintrusive, these methods are extremely time-intensive and require a high level of observer training; thus, they are burdensome for clinical and large population research purposes. This work is a first milestone in a long-term project on non-invasive early observation of children in order to aid in risk detection and research of neurodevelopmental disorders. We focus on providing low-cost computer vision tools to measure and identify ASD behavioral signs based on components of the Autism Observation Scale for Infants (AOSI). In particular, we develop algorithms to measure responses to general ASD risk assessment tasks and activities outlined by the AOSI which assess visual attention by tracking facial features. We show results, including comparisons with expert and nonexpert clinicians, which demonstrate that the proposed computer vision tools can capture critical behavioral observations and potentially augment the clinician’s behavioral observations obtained from real in-clinic assessments.”

The severity of core autism symptoms in young children goes hand in hand with the degree of the childrens difficulty with motor tasks, according to a study published in the April issue of the Adapted Physical Activity Quarterly. Early interventions, such as therapies that target social and communicative behavior, may alter autisms course. Building strong motor skills may help children with autism develop better social and communicative skills, especially in physically demanding play, the researchers say.
The average child with autism is 18 months old before his or her parents first begin to be concerned. Given the importance of early intervention, its crucial that parents and doctors both catch on to the symptoms as soon as possible. A study published in European Child and Adolescent Psychiatry finds that two autism screens are better than one at identifying toddlers who need specialized clinical services. These screens, such as the Modified Checklist for Autism in Toddlers (M-CHAT) and the Early Screening of Autistic Traits (ESAT), are used not to diagnose autism, but rather to identify children who need more specialized attention for example, from a child psychiatrist or a behavioral therapist.
Evidence of Reproductive Stoppage in Families With Autism Spectrum Disorder: A Large, Population-Based Cohort StudyPublished June 18, 2014 in JAMA Psychiatry
OBJECTIVE: To examine stoppage in a large, population-based cohort of families in which a child has received a diagnosis of ASD. CONCLUSIONS AND RELEVANCE: These results provide the first quantitative assessment and convincing statistical evidence of reproductive stoppage related to ASD. These findings have implications for recurrence risk estimation and genetic counseling.
Research published in JAMA Psychiatry shows that parents who have a child with autism are about a third less likely to choose to continue having children compared to parents who do not have a child with ASD. In the study, this “reproductive stoppage” did not occur until the child started showing symptoms or received a diagnosis of ASD. This led researchers to conclude that it was a conscious decision to stop having children, rather than another factor such as fertility problems.
Reversal of Autism-Like Behaviors and Metabolism in Adult Mice with Single-Dose Antipurinergic TherapyPublished June 17, 2014 in Translational Psychiatry
Researchers at UC San Diego have discovered that suramin, a drug that was originally developed to treat African sleeping sickness, reverses autism-like social behaviors in mice. This study proposes that the social difficulties and metabolism issues found in individuals with ASD could be improved with the use of suramin even in adults. While suramin has not been tested in humans, these findings could direct future research for autism therapies.
Longitudinal research has demonstrated that social outcomes for adults with autism are restricted, particularly in terms of employment and living arrangements.

Having an accurate estimate of the economic cost of autism has many implications for service and system planning. The most recent estimates are almost a decade old and had to rely on many estimates for which there were no good data. Today in JAMA Pediatrics, researchers, including ASF Scientific Advisory Board member Dr. David Mandell, updated older estimates and further expanded our understanding of costs by estimating them for two countries: the United States and the United Kingdom. They also estimated costs separately for children and adults, and for individuals with autism with and without intellectual disability. To estimate costs, researchers reviewed the literature on related studies, conducting a thorough search of studies that estimated direct costs, such as education and service use costs, as well as indirect costs, such as lost wages for family members and the individual with autism. They found that for individuals with autism and intellectual disability, the average lifetime cost was $2.4 million in the US and $2.2 million in the UK. For individuals without intellectual disability, the average cost was $1.4 million in both the US and the UK. For children with autism, the largest costs were for special education and parents lost wages. For adults with autism, the largest costs were residential care and lost wages.
The cortex, the outer layer of the brain, grows rapidly in early childhood in people with autism and thins differently with age than it does in controls, two new studies report. Together, the studies support the theory that the brain grows too quickly and shrinks too soon in people with autism.

“Autism affects males more than females, giving rise to the idea that the influence of steroid hormones on early fetal brain development may be one important early biological risk factor. We identified all amniotic fluid samples of males born between 1993 and 1999 who later received diagnoses of autism, Asperger syndrome or PDD-NOS (pervasive developmental disorder not otherwise specified) (n=128) compared with matched typically developing controls. Concentration levels of ?4 sex steroids (progesterone, 17?-hydroxy-progesterone, androstenedione and testosterone) and cortisol were measured with liquid chromatography tandem mass spectrometry. All hormones were positively associated with each other and principal component analysis confirmed that one generalized latent steroidogenic factor was driving much of the variation in the data. The autism group showed elevations across all hormones on this latent generalized steroidogenic factor (Cohen’s d=0.37, P=0.0009) and this elevation was uniform across ICD-10 diagnostic label. These results provide the first direct evidence of elevated fetal steroidogenic activity in autism. Such elevations may be important as epigenetic fetal programming mechanisms and may interact with other important pathophysiological factors in autism.”

Researchers at the University of Cambridge have found that children who later develop autism are exposed to heightened levels of steroid hormones (such as testosterone, progesterone and cortisol) in the womb. This finding may be related to the fact that autism affects males more than females.
People with autism tend to carry mutations that duplicate or delete several genes at once, according to a large study published in the American Journal of Human Genetics. Previous studies have shown that people with autism have more large deletions or duplications of DNA, also known as copy number variations (CNVs), than controls do. The new study, the largest to look at CNVs in people with autism thus far, confirms this finding. It also found that in people with autism, the CNVs are more likely to affect genes linked to intellectual disability and fragile X syndrome.

Brain-Expressed Exons Under Purifying Selection are Enriched for De Novo Mutations in Autism Spectrum DisorderPublished May 25, 2014 in Nature Genetics
A universal challenge in genetic studies of autism spectrum disorders is determining whether a given DNA sequence alteration will manifest as disease. Among different population controls, we observed, for specific exons, an inverse correlation between exon expression level in brain and burden of rare missense mutations. For genes that harbor de novo mutations predicted to be deleterious, we found that specific critical exons were significantly enriched in individuals with ASD relative to their siblings without ASD. Furthermore, our analysis of genes with high exonic expression in brain and low burden of rare mutations demonstrated enrichment for known ASD-associated genes and ASD-relevant fragile-X protein targets. Our results suggest that brain-expressed exons under purifying selection should be prioritized in genotype-phenotype studies for ASD and related neurodevelopmental conditions.

Corticosteroid Therapy in Regressive Autism: A Retrospective Study of Effects on the Frequency Modulated Auditory Evoked Response (FMAER), Language, and BehaviorPublished May 15, 2014 in BMC Neurology
Steroid treatment was associated with a significantly increased FMAER response magnitude, reduction of FMAER response distortion, and improvement in language and behavior scores. This was not observed in the non-treated group. These pilot findings warrant a prospective randomized validation trial of steroid treatment for R-ASD utilizing FMAER, EEG, and standardized ASD, language and behavior measures, and a longer follow-up period. Children with R-ASD, and without concurrent evidence for an epileptic encephalopathy such as the Landau-Kleffner syndrome, who receive steroid therapy, show improvement in a language specific electrophysiological brain function indicator, as measured with the FMAER. Additionally, they appear to show improvement in language and behavior performance. At the level utilized in this study, steroid therapy did not appear to result in recognized, lasting morbidities.

“Autism spectrum disorder (ASD) is a developmental disorder defined by behavioral symptoms that emerge during the first years of life. Associated with these symptoms are differences in the structure of a wide array of brain regions, and in the connectivity between these regions. However, the use of cohorts with large age variability and participants past the generally recognized age of onset of the defining behaviors means that many of the reported abnormalities may be a result of cascade effects of developmentally earlier deviations. This study assessed differences in connectivity in ASD at the age at which the defining behaviors first become clear. There were 113 24-month-old participants at high risk for ASD, 31 of whom were classified as ASD, and 23 typically developing 24-month-old participants at low risk for ASD. Utilizing diffusion data to obtain measures of the length and strength of connections between anatomical regions, we performed an analysis of network efficiency. Our results showed significantly decreased local and global efficiency over temporal, parietal and occipital lobes in high-risk infants classified as ASD, relative to both low- and high-risk infants not classified as ASD. The frontal lobes showed only a reduction in global efficiency in Broca’s area. In addition, these same regions showed an inverse relation between efficiency and symptom severity across the high-risk infants. The results suggest delay or deficits in infants with ASD in the optimization of both local and global aspects of network structure in regions involved in processing auditory and visual stimuli, language and nonlinguistic social stimuli.”

Two autism-related disorders fragile X syndrome and tuberous sclerosis complex share disruptions in the immune system despite major differences in the individual genes affected, reports a study in Molecular Autism. An abnormally regulated immune system is linked to some forms of autism, but exactly how genetic changes in the immune system contribute to autism is unclear.
A small study published 3 April in Molecular Autism found that 98 percent of mothers of children with autism have unusual responses to sensory stimuli, including light, sound and touch. Up to 90 percent of children with autism show sensory problems, fixating on or avoiding certain smells, sounds or textures. As a result, the newest edition of the Diagnostic and Statistical Manual of Mental Disorders lists abnormal sensitivity in one or more of the five senses as a core diagnostic feature of autism. Its unclear whether genetics contributes to these sensory patterns, but a larger study examining the relationship between unusual sensory response, autism traits and additional disorders in family members may clarify the link.

A substantial proportion of risk for developing autism spectrum disorders (ASD) resides in genes that are part of specific, interconnected biological pathways, according to researchers from the Icahn School of Medicine at Mount Sinai, who conducted a broad study of almost 2,500 families in the United States and throughout the world. The study was published in The American Journal of Human Genetics. The researchers reported numerous copy number variations (CNVS) affecting genes, and found that these genes are part of similar cellular pathways involved in brain development, synapse function and chromatin regulation. Individuals with ASD carried more of these CNVs than individuals in the control group, and some of them were inherited while others were only present in offspring with ASD.
Certain DNA repeats that increased exponentially during human evolution are directly related to the severity of autism symptoms, according to a preliminary study published in PLoS Genetics.

Atypical brain connectivity in areas that affect social interactions have been found in people with autism spectrum disorders. This difference in connectivity is found in networks of the brain that help individuals understand what others are thinking, and to understand others’ actions and emotions. Up until now, it was thought that these areas of the brain were under-connected in people with autism, but this study shows that more often than not, they are actually over-connected. The study also found that the greater the difference in neural connectivity, the more social interactions were impaired.

The NIH is requesting additional input from the scientific community, health professionals, self-advocates and patient advocates about the research implications of recent changes to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnostic criteria for Autism Spectrum Disorders (ASD). Responses will be accepted through May 12, 2014.
The CDC has released its 2014 Community Report on Autism, which gives details behind the new 1 in 68 number, as well as additional state-by-state prevalence information.
IACC Issues Statement Regarding Implications of Changes in the Diagnostic Criteria for Autism Spectrum DisorderPublished April 2, 2014 in Interagency Autism Coordinating Committee
Today, on World Autism Awareness Day 2014, the Interagency Autism Coordinating Committee (IACC), issued a statement regarding the implications of changes in the diagnostic criteria for ASD that were made in the most recent update of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Of particular interest are the scientific, practice, and policy implications as DSM-5 is implemented in real-world settings, especially with respect to allocation of services.
Hilibrand Autism Symposium: Carving a Place in the World for Young Adults With Autism Spectrum DisordersPublished April 1, 2014 in Hilibrand Autism Symposium
Every adult wants to lead a meaningful life, and individuals with autism spectrum disorders (ASD) are no different. More and more, people with ASD are working, living, and engaging in their communities, and are being recognized for their strengths and talents. Yet the questions still remain: What do young adults with ASD need to transition to being productive members of society whose skills and interests are used and valued? How can professionals, parents, advocates, and others ensure that a place in the world is carved out for these individuals? This conference will present new research and innovative models to spark a dialogue about current challenges and effective solutions to helping adults with ASD obtain and maintain work, social connections, and independence.ASF Scientific Advisory Board Member David Mandell will be giving the keynote address.Tune into the Hilibrand Autism Symposium lifestream today from 9:00am to 4:30pm at http://www.ujafedny.org/autism-symposium/
When it comes to autism prevalence, it can be difficult to separate real risks from false rumors. The topics that gain the most media coverage aren’t always the ones with the greatest affect on autism risk. The risk ratio can give perspective where isolated news stories dont.
New evidence suggests that autism begins in the brain before birth when brain cells fail to develop properly. In this study, the abnormalities in the brain cells were not uniform, showing autism’s wide range of symptoms and severity. This better understanding of prenatal development of the brain cells of people with autism underscores the importance of early identification and intervention.
Researchers have developed a method to isolate a single mutant cell from thousands of others, they reported in the March issue of Nature Methods. The new approach will allow researchers to precisely engineer and study human cells without altering the genome. Ultimately, the method could be used to alter an individuals cells before returning them to his or her body.
Autism Science Foundation Issues Request for Applications: 2014 Undergraduate Summer Research GrantsPublished March 17, 2014 in Autism Science Foundation
The Autism Science Foundation invites applications from highly qualified undergraduates interested in pursuing basic and clinical research relevant to autism spectrum disorders during the summer. The proposed research must be scientifically linked to autism or a closely related field. Autism Science Foundation will consider all areas of related basic and clinical research including but not limited to: human behavior across the lifespan (language, learning, communication, social function, epilepsy, sleep, self-injurious behavior, catatonia), neurobiology (anatomy, development, neuro-imaging), pharmacology, neuropathology, human genetics, genomics, epigenetics, epigenomics, immunology, molecular and cellular mechanisms, studies employing model organisms and systems, and studies of treatment and service delivery.
Communication Interventions for Minimally Verbal Children With Autism: A Sequential Multiple Assignment Randomized TrialPublished March 13, 2014 in Child and Adolescent Psychiatry
Minimally verbal school-aged children can make significant and rapid gains in spoken spontaneous language with a novel, blended intervention that focuses on joint engagement and play skills and incorporates an SGD. Future studies should further explore the tailoring design used in this study to better understand childrens response to treatment.

The risk of certain autism spectrum disorders is highest in firstborn children and declines in each additional sibling born to the same mother, reports a large Finnish study published in Paediatric and Perinatal Epidemiology. When the researchers looked at Asperger syndrome, pervasive developmental disordernot otherwise specified (PDD-NOS) and childhood autism, in which symptoms appear before the age of 3, as a group, they found that a diagnosis is most common in firstborns. The latter two conditions are now considered part of the autism diagnosis. When they looked at each diagnosis separately, the researchers found that the firstborn effect holds for Asperger and PDD-NOS, while second-born children are at the highest risk for childhood autism.
Autism is defined based on a wide variety of behavioral symptoms, but it’s precisely this variation along with a complex genetic background that makes it tricky to connect behavior to the underlying genes. A new algorithm may make this challenge a bit easier to solve. The algorithm, which employs a form of artificial intelligence that learns as it goes, analyzes behavioral data and has learned to recognize six genetic disorders associated with autism, according to research published in Molecular Autism. The researchers hope to use these behavioral signatures to hone their search for the genetic underpinnings of idiopathic autism, for which there is no known cause.
Autism researchers and advocates often express concern that the average age of autism diagnosis in the U.S. hovers around 4 years even though most cases of the disorder can be reliably identified by age 2. In this highly contentious field, the need for early diagnosis and early intervention is one of the few areas of agreement. Surprisingly, though, there has been little hard evidence that earlier diagnosis improves the lives of people with autism in the long term. At last, this evidence is becoming available. The field turned toward more rigorous studies a decade or so ago, and many of those studies, focused on children between about 2 and 4 years old, are starting to bear fruit.
A Higher Mutational Burden in Females Supports a Female Protective Model in Neurodevelopmental DisordersPublished February 27, 2014 in American Journal of Human Genetics
Researchers have more clues as to why more boys than girls are diagnosed with Autism Spectrum Disorder. A new study in the American Journal of Human Genetics suggests that for boys, it takes less of a genetic hit to cause autism than it does for girls. The study continues to say that when it does appear in girls, it is due to a much more severe genetic hit, usually resulting in much more severe autism symptoms.
Even at rest, the brains of people with autism manage more information than those of their peers, according to a new study that may provide support for the so-called intense world theory of autism. The research, which was published in Frontiers in Neuroinformatics, included nine children with Asperger syndrome, aged between 6 and 14 and ten age-matched typical children. The researchers scanned their brains using magnetoencephalography (MEG), a noninvasive method that doesnt require lying in a noisy, confined space as magnetic resonance imaging does. The results suggest that in the same boring situation, people with autism process more information than their typical peers.
A rigorous new study confirms that boys with autism tend to score higher on tests of spatial and analytical abilities than on those for verbal skills. But the gap decreases by the time they reach 10 years of age. This suggests that the trait cannot be used to define children with autism or their families, the researchers say. Instead, it may be a pattern of development common in children with autism or other developmental disorders. The report was published in the January issue of the American Journal on Intellectual and Developmental Disabilities.
Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. A new study in The Lancet states that industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. Building on a 2006 study in which researchers identified five industrial chemicals as developmental neurotoxicants (lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene), epidemiological studies have documented six additional developmental neurotoxicants manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers. To protect children from exposure to such harmful chemicals, researchers say that untested chemicals should not be presumed to be safe to brain development.
In utero exposure to the epilepsy drug valproic acid (VPA), which ups the risk of autism, may alter the composition of gut bacteria in rodents, according a study published in Brain Behavior and Immunity. Rats and mice exposed to VPA in utero have social deficits, repetitive behaviors and anxiety, making them a good model for studying autism. It is unclear exactly how VPA exposure leads to these symptoms, however.
A commercially available line of neurons generated from induced stem cells would serve as a good control for autism research, according to a study published in Psychopharmacology. Characterizing these neurons in detail shows that they express most of the genes linked to autism and look like typical, albeit immature, cells. Induced pluripotent stem cells, or iPSCs, are skin or blood cells reverted to a state from which they can become any cell in the body. Researchers can use the technique to turn cells from people with a neuropsychiatric disorder into neurons. They can then compare the neurons with those from controls to gain understanding of the disorder.
The blood pressure drug bumetanide normalizes a deficit in brain activity in two rodent models of autism, according to a study published in Science. The study hints at a mechanism underlying the drugs benefits for people with autism. Neurochlore, a company based in Marseilles, France, is testing bumetanide as a treatment for autism. In the first phase, 27 children with autism showed some improvement in their autism symptoms; the researchers are continuing the trial in Europe with more participants.
A week after announcing that the federal government will pay for tracking devices for kids with autism, officials are offering more details about how families can access the technology. All applications must go through law enforcement agencies, so organizations and schools should work with local police to put programs in place. Police departments that receive money through the federal Byrne grant will be responsible for designing and administering their local program and determining how tracking devices are distributed.

Most of the children who would lose their autism diagnosis under the diagnostic criteria released last year will fall under the new category of social (pragmatic) communication disorder (SDC), reports a large study of Korean children. The study was published last week in the American Academy of Child and Adolescent Psychiatry. SCD is a condition that includes severe social and communication deficits but lacks the repetitive behaviors and restricted interests seen in autism.
Report to Congress on Activities Related to Autism Spectrum Disorder and Other Developmental Disabilities Under the Combating Autism Act of 2006 and Combating Autism Reauthorization Act of 2011 (FY 2010 – FY 2012)Published February 1, 2014 in Department of Health and Human Services
This Report to Congress is required by Public Law 112-32, the Combating Autism Reauthorization Act of 2011. The report describes progress and expenditures made in autism spectrum disorder (ASD)- related research and services activities across the Department of Health and Human Services, the Department of Education, the Department of Defense, the Environmental Protection Agency and the National Science Foundation from fiscal years 2010- 2012.
In 2009, the Centers for Medicare & Medicaid Services (CMS) contracted with L&M Policy Research (L&M) and its partners, Truven Health Analytics (formerly the health care business of Thomson Reuters) and the National Association of State Directors of Developmental Disabilities Services, to address the growing need among federal and state policymakers and stakeholders for accurate and comprehensive information regarding available services and supports for people with ASD. The Autism Spectrum Disorders (ASD) State of the States of Services and Supports for People with ASD report stemmed from the Interagency Autism Coordinating Committee’s (IACC’s) 2010 and 2011 Strategic Plans. The overall goal of this project was to capture information about services for people with ASD across all federal and state-level agencies and offices that could serve as a useful tool and be updated on an as-needed basis. In addition, the project aimed to identify gaps in data.
Effects of a Self-Monitoring Device on Socially Relevant Behaviors in Adolescents with Asperger Disorder: A Pilot StudyPublished January 22, 2014 in Assistive Technology
This article reports the results of two case studies. Two middle school-aged participants with high-functioning autism spectrum disorders were taught to self-monitor behaviors impacting their social acceptance by peers in their general education settings: oral self-stimulatory behaviors and conversation skills. Results indicate that the intervention was effective to some degree with both participants. As a result of the self-monitoring intervention, one participant decreased self-stimulatory behaviors; however, his data were highly variable throughout the study though lower on average during intervention than in baseline. The other participant’s targeted skills in communication were only slightly improved. Self-monitoring using a vibrating reminder appears to be a low-cost intervention with high levels of social acceptability, low training requirements for teachers or students, and no social stigma.
Adults with autism usually understand in theory when and why others may feign emotions, but they dont recognize those expressions in real-life situations, reports a study published in Autism Research. This inability to guess what triggered someones subtle expression can lead to social missteps congratulating instead of consoling a disappointed friend, for example.
Like watching a foreign movie that was badly dubbed, children with autism spectrum disorders (ASD) have trouble integrating simultaneous information from their eyes and their ears, according to a Vanderbilt study. The study, led by Mark Wallace, Ph.D., director of the Vanderbilt Brain Institute, is the first to illustrate the link and strongly suggests that deficits in the sensory building blocks for language and communication can ultimately hamper social and communication skills in children with autism.
One of the frustrations that parents of children with autism most commonly voice is the long wait for a diagnosis. In the meantime, the children grow up and out of the critical period for early intervention. The scenario for adults seeking an autism diagnosis is even grimmer, as there are fewer practitioners experienced in caring for adults with autism than in caring for children with the disorder. There are few comprehensive statistics about waiting times, but the bottlenecks in access to autism diagnosis and care are widely acknowledged. These concerns are spurring the medical community to take a hard look at the failings of professional training in contributing to the problem.
The motor problems seen in Rett syndrome may be the result of deficits in a pathway that mediates reward in the striatum, a brain region that coordinates movement, according to a study published in Brain Structure and Function. Studies have shown that loss of MeCP2 in the front of the brain is sufficient to lead to Rett-like symptoms in mice. The forebrain includes the striatum, which integrates information from other brain regions to help plan and coordinate movement. The new study found that mice that model Rett syndrome have significantly less dopamine a chemical messenger that mediates reward in the striatum than controls do. The study suggests that changes in dopamine levels influence neural circuits in the striatum that regulate motor function.
Researchers have standardized labels for nearly 300 traits of autism, drawn from 24 diagnostic tests for the disorder, they reported in Neuroinformatics. They can use these terms to search for certain traits among large catalogs of the genetics and symptoms of people with autism. The new study aims to build a defined list, or ontology, of the traits these tests assess. The goal is to allow researchers to compare results across different diagnostic tests and identify the same features, regardless of the test used. The new tool can also help classify individuals with autism into subgroups, which may reflect different causes of the disorder.
Carrying a duplication of the 22q11.2 chromosomal region may protect against schizophrenia, suggests a study published 12 November in Molecular Psychiatry. This is the first evidence of a genetic region that lowers the risk of a disorder rather than increases it. Deletion of this part of chromosome 22 is the strongest known risk factor for schizophrenia, and is also linked to autism, attention deficit hyperactivity disorder and anxiety in childhood. Various other copy number variations (CNVs), or stretches of a chromosome that are deleted or duplicated multiple times in the genome, have been linked to schizophrenia, autism and other neurological conditions. The new study is the first to pinpoint a CNV that lowers the risk of a disorder, however.
Pregnant women who were diagnosed with a bacterial infection during a hospital visit were more likely to have their child be diagnosed with autism spectrum disorder, a study in the Journal of Autism and Developmental Disorders reports. “Multiple maternal infections and bacterial infections occurring during late pregnancy, particularly those diagnosed in a hospital setting, were associated with a higher risk of autism,” the researchers reported.
Next February, researchers plan to begin work on a $1.2 million project that aims to link specialized psychiatric units across the U.S. to investigate the most severe and challenging autism cases. The study will include the six largest of the nine specialized psychiatric hospital programs for autism in the U.S. About 1,000 individuals with autism, aged 4 to 20, typically spend between 20 and 25 days at a time in these programs. We think this is an area we can contribute [to], says lead investigator Matthew Siegel, medical director of the developmental disorders program of Spring Harbor Hospital in Maine. If not us, who? We have the expert clinicians and see hundreds of these kids.
Babies later diagnosed with autism tend to stare at objects after picking them up, a behavior known as sticky gaze, at much later ages than controls do, according to a study published in Behavioral Brain Research. This delay may contribute to problems with joint attention the tendency to seek out and follow others gaze in autism, the researchers say.
Microbiota Modulate Behavioral and Physiological Abnormalities Associated with Neurodevelopmental DisordersPublished December 19, 2013 in Cell
Neurodevelopmental disorders, including autism spectrum disorder (ASD), are defined by core behavioral impairments; however, subsets of individuals display a spectrum of gastrointestinal (GI) abnormalities. We demonstrate GI barrier defects and microbiota alterations in the maternal immune activation (MIA) mouse model that is known to display features of ASD. Oral treatment of MIA offspring with the human commensal Bacteroides fragilis corrects gut permeability, alters microbial composition, and ameliorates defects in communicative, stereotypic, anxiety-like and sensorimotor behaviors. MIA offspring display an altered serum metabolomic profile, and B. fragilis modulates levels of several metabolites. Treating naive mice with a metabolite that is increased by MIA and restored by B. fragilis causes certain behavioral abnormalities, suggesting that gut bacterial effects on the host metabolome impact behavior. Taken together, these findings support a gut-microbiome-brain connection in a mouse model of ASD and identify a potential probiotic therapy for GI and particular behavioral symptoms in human neurodevelopmental disorders.

Deficits in eye contact have been a hallmark of autism since the condition’s initial description. They are cited widely as a diagnostic feature and figure prominently in clinical instruments; however, the early onset of these deficits has not been known. Here we show in a prospective longitudinal study that infants later diagnosed with autism spectrum disorders (ASDs) exhibit mean decline in eye fixation from 2 to 6 months of age, a pattern not observed in infants who do not develop ASD. These observations mark the earliest known indicators of social disability in infancy, but also falsify a prior hypothesis: in the first months of life, this basic mechanism of social adaptive action–eye looking–is not immediately diminished in infants later diagnosed with ASD; instead, eye looking appears to begin at normative levels prior to decline. The timing of decline highlights a narrow developmental window and reveals the early derailment of processes that would otherwise have a key role in canalizing typical social development. Finally, the observation of this decline in eye fixation–rather than outright absence–offers a promising opportunity for early intervention that could build on the apparent preservation of mechanisms subserving reflexive initial orientation towards the eyes.

In the past, studies have raised concern about an association between the use of a certain type of antidepressant known as selective serotonin reuptake inhibitors (SSRIs) during pregnancy and an increased risk of autism spectrum disorders in the child. A new study now shows no significant association between maternal use of SSRIs during pregnancy and autism spectrum disorder in the child. However, the children were at a higher than usual risk of being diagnosed with autism if their mother had taken the drugs for depression or anxiety prior to the pregnancy, suggesting a possible link between the mother’s preexisting mental health condition and the child’s development of an ASD.
People who carry high-risk genetic variants for schizophrenia and autism have impairments reminiscent of disorders such as dyslexia, even when they do not yet have a mental illness, a new study has found. Researchers report that people with these copy number variants (CNVs) but no diagnosis of autism or a mental illness still show subtle brain changes and impairments in cognitive function. The findings offer a window into the brain changes that precede severe mental illness and hold promise for early intervention and even prevention, researchers say.
Mice with a duplication of SHANK3, a gene with strong links to autism, are hyperactive and manic, reports a study published in Nature.The mice produce about 50 percent more SHANK3 protein than their genetically typical counterparts, the scientists found, much like people with an extra copy of the gene do. The mice also show signs of hyperactivity. The team observed on further testing that the SHANK3 mice show behaviors typically seen in people going through manic episodes. The mice are easier to startle, eat more, have disrupted sleeping patterns and show heightened sensitivity to amphetamine. The mice also have spontaneous seizures.
A long-awaited study has confirmed the fears of Somali residents in Minneapolis that their children suffer from higher rates of a disabling form of autism compared with other children there. The study by the University of Minnesota, the Centers for Disease Control and Prevention, and the research and advocacy group Autism Speaks found high rates of autism in two populations: About one Somali child in 32 and one white child in 36 in Minneapolis were on the autism spectrum. But the Somali children were less likely than the whites to be high-functioning and more likely to have I.Q.s below 70. (The average I.Q. score is 100.) The study offered no explanation of the statistics.
Peer solicitation a child inviting another to play can improve reciprocal social interaction among children with autism, according to a recent Vanderbilt University study. While the children with autism in the study initiated and engaged in less play overall than typically developing children, the researchers found that other children can facilitate and increase interactions by simple requests. These findings highlight the pivotal role that peers have in social interaction, noting that it only takes a single child to prompt other children with or without autism to interact.
Researchers at Karolinska Institutet in Sweden have developed a new screening tool to facilitate the diagnosis of Autism Spectrum Disorder in adults. The test is presented in the scientific journal Molecular Autism and is unique in that researchers have, as part of their evaluation, compared the group diagnosed with Autism Spectrum Disorder with psychiatric patients. In adults, distinguishing Autism Spectrum Disorder from other psychiatric conditions can be a problem, as their symptoms often overlap or are similar to those in schizophrenia, attention deficit and hyperactivity disorder (ADHD) or severe personality disorders.
A study in Brain Research shows a difference in how auditory nerve fibers develop may explain why children with autism process sounds a fraction of a second more slowly than typically developing children do. It is known that the brains response to sound speeds up as children age. This boost in speed is known to be accompanied by the maturation of white matter the nerve fibers that connect brain regions. It was once believed that in children with autism, the white matter didn’t mature with age like it does in typically-developing children. However, it is now believed that it does mature with age in children with autism, just in a different way.
More information has come about about the gut microbes study in Cell. “I’d want to know more about the mechanism by which the bacteria altered behavior in the mice before beginning to translate the findings to humans” says Emanuel DiCicco-Bloom, a neuroscientist at Rutgers University and member of the ASF Scientific Advisory Board.
Caltech researchers gave probiotics to mice that had been bred to have autism-like symptoms and found promising results. After being given the probiotics, the mice were more communicative and less anxious. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
Anxiety runs in families with autism, hinting that the two conditions may share a common origin, suggests a twin study published recently in the Journal of Child Psychology and Psychiatry. Compared with controls, the children who had autism or some features of the disorder experienced more of all forms of anxiety, including social anxiety and episodes of panic, according to parent surveys. They scored especially high on generalized and separation anxiety.
A new study conducted by the Yale Child Study Center shows promising results concerning the use of the hormone oxytocin. The study found that oxytocin, given as a nasal spray,enhanced brain activity while processing social information in children with autism spectrum disorders. This means brain centers associated with reward and emotion recognition responded more during social tasks when the children in the study received oxytocin.
Autism spectrum disorder is more common in males than females. An underrepresentation of females in the ASD literature has led to limited knowledge of differences in social function across the sexes. A study on face perception has shown that despite being closely matched for symptoms, IQ, and age, the girls showed more pronounced atypical brain response, which suggests they are indeed employing compensatory strategies to look as good as they do.
Scientists at Yale have identified which types of brain cells and regions of the brain are affected by genetic mutations linked to autism spectrum disorders. Researchers state that this new discovery has the potential for new types of autism treatments. We may not need to treat the whole brain, they say; only particular areas of the brain may be affected by autism at certain times.
In what are believed to be the first studies of their kind, Cedars-Sinai researchers recording the real-time firing of individual nerve cells in the brain found that a specific type of neuron in a structure called the amygdala performed differently in people who suffer from autism spectrum disorder than in those who do not. Researchers discovered that the mouth, much more than the eyes, is what people with autism focus on to decipher emotions expressed through facial expressions.
Students with autism who attend community colleges two-year local institutions tend to succeed if they study science, technology, engineering or mathematics (STEM), reports a new study published October 26 in the Journal of Autism and Developmental Disorders. Students who studied STEM subjects were less likely to drop out and were twice as likely to transfer to a four-year university than their non-STEM peers.
New research out of the University of Cambridge and published in the journal Molecular Autism found that people with autism are more likely to have synaethesia, which involves experiencing a mixing of the senses, such as seeing colors when they hear sounds. Both autism and synaesthesia involve neural over-connectivity, perhaps the reason why synaesthesia is disproportionately common in autism.
In a new study published in the Journal of the American Academy of Child and Adolescent Psychiatry, 3,666 children were assessed on their ability to correctly recognize emotions by looking at faces. Children with autistic-like social communication difficulties were compared with children without such difficulties. Autistic-like social communication difficulties were associated with poorer recognition of emotion from social motion cues in both genders, but were associated with poorer facial emotion recognition in boys only. Relatively good performance of girls on the task of facial emotion discrimination may be due to compensatory mechanisms, though more research is needed in this area.
People with autism show differences from controls in the levels of microRNAs, small noncoding bits of RNA, in the social and sound-processing parts of the brain. MicroRNAs, or miRNAs, bind to messenger RNAs, which code for protein, and flag them for degradation. Each miRNA can interfere with the production of several proteins. Of the more than 5,000 miRNAs and other small noncoding RNAs that the researchers screened, they found 3 miRNAs that are dysregulated in these regions in people with autism compared with controls.
The largest genetic analysis yet conducted of people lacking a brain structure called the corpus callosum shows that the condition shares many risk factors with autism. The study was published PLoS Genetics. The corpus callosum is the thick bundle of nerve fibers that connects the two hemispheres of the brain. People lacking this structure, a condition called agenesis of the corpus callosum (AgCC), often have social impairments, and roughly one-third of adults meet diagnostic criteria for autism. Children with autism seem to have a smaller corpus callosum than controls do.
A new imaging technique that can assemble finely detailed pictures of an individual mouses brain in less than a day is being used to explore mouse models of autism. The automated technique cuts a mouse brain into 280 thin slices, which are scanned by a powerful microscope and the resulting images are then stitched together into a three-dimensional view. The researchers used this technique to investigate the imbalance of excitatory and inhibitory signals in a mouse model of 16p11.2 deletion. People missing this chromosomal region have an increased risk for autism, and about one-quarter have epilepsy, in which an excess of excitatory signals causes seizures.
New research out of Vanderbilt Peabody College of education and human development found that using speech-generating devices, such as iPads, to encourage children ages 5 to 8 to develop speaking skills resulted in the subjects developing considerably more spoken words compared to other interventions. All of the children in the study learned new spoken words and several learned to produce short sentences as they moved through the training.
Symptoms of autism spectrum disorders may appear as early as 6 months, but parent concern, which can precipitate evaluation, often lags significantly. The presence of typical or atypical older siblings can change parents’ sensitivity to departures from typical development. This study investigated type and age of parent’s first concerns in toddlers with autism spectrum disorder, prior to diagnosis. Participants had (1) at least one older sibling with autism spectrum disorder (Sibs-ASD); (2) only typically developing older siblings (Sibs-TD), or (3) were only/oldest (No-Sibs). Specific autism spectrum disorder diagnoses and symptom severity were similar among groups. Developmentally, No-Sibs showed the largest delays, followed by Sibs-TD, followed by Sibs-ASD. Mean age of first concern was 16 months for No-Sibs, 14 months for Sibs-TD, and 10 months for Sibs-ASD. Age of first concern differed significantly by group, even after controlling for mother’s age and education. Concern about language was prevalent in all groups. Thus, the presence of an older child with typical or, especially, atypical development was associated with earlier concerns for the affected child, despite milder developmental delays. These findings underscore the importance of encouraging parents to report concerns to pediatricians, routine standardized screening for autism spectrum disorder, and the need for pediatrician vigilance, especially for only or oldest children.
Today, in a publication in Nature, scientists show that it is possible to identify markers of autism in the first 6 months of life, much before children begin to show symptoms. In this study, these markers predicted both diagnosis and level of disability 2 12 years later when the children were evaluated by expert clinicians. The scientists used eye-tracking technology to measure the way babies visually engage with others. If these results are replicated in larger samples, these procedures might in the future empower primary care physicians to screen for autism as part of routine well-baby check ups. Equal energy and resources will then have to be invested in improving access to early treatment so that children are afforded the opportunity to fulfill their full potential.
Clinicians around the world diagnose children with autism, but is autism the same disorder around the world? A team of researchers has begun testing this question by comparing children in two European countries. The American definition of autism travels well across international borders in the case of British and Finnish children, they reported in the journal Autism. However, when the researchers compared mild traits of autism collectively referred to as broad autism phenotype, or BAP those of children from Finland do not line up well with descriptions in the DSM-5. This may be because of differences in language, culture and genetics between Finland and the U.K.
The objectives of this study were to examine rates and predictors of psychotropic use and multiclass polypharmacy among commercially insured children with autism spectrum disorders. Despite minimal evidence of the effectiveness or appropriateness of multidrug treatment of ASD, psychotropic medications are commonly used, singly and in combination, for ASD and its co-occurring conditions. Our results indicate the need to develop standards of care around the prescription of psychotropic medications to children with ASD.
New research shows a genetic link between individuals with autism and family members with specific speech and language difficulties otherwise unexplained by cognitive or physical problems. Researchers discovered that genes in a small region of two chromosomes can lead to one family member developing autism and another family member only developing language impairment.
Researchers have coaxed human stem cells to develop into simplified mini-brains, with regions resembling discrete brain structures, reported in the journal Nature. A spinning culture system prods stem cells to develop into neurons in three dimensions. The culture system is a gelatinous protein-rich mixture that provides both the structural support and nutrients required for neuronal development. Already, the researchers have shown that these artificial brains may model human disorders better than real mouse brains do.
New research from the University of Utah and published in the journal Pediatrics has uncovered an association between autism spectrum disorders and a small increase in the amount of weight a mother gains during pregnancy. These findings suggest that weight gain during pregnancy is not the cause of ASD but rather may reflect an underlying process that it shares with autism spectrum disorders, such as abnormal hormone levels or inflammation.
Mutations in the autism-linked protein NHE6 may block the development of neuronal junctions by interfering with a growth factor called BDNF, according to a study published in the journal Neuron. The results suggest that drugs that enhance BDNF signaling could treat some forms of autism, the researchers say.
According to a new study in the journal Pediatrics, kids with autism are often prescribed mood altering drugs, sometimes many at one time and for extended periods of time. These drugs include antipsychotics, antidepressants, and anti-anxiety medications. The study states that this practice occurs despite minimal evidence of the effectiveness or appropriateness of multidrug treatment of ASD.
Research investigating expressivity in children with autism spectrum disorder has reported flat affect or bizarre facial expressivity within this population; however, the impact expressivity may have on first impression formation has received little research input until now. A recent study published in the journal Autism suggests that typically developing children can form negative impressions of autistic children in as little as a thirty second encounter. The lead researcher on the study suggested that we need to focus on educating typically developing children to help break through the possible negative first impressions that can occur.

Phelan-McDermid syndrome (PMDS) is a complex neurodevelopmental disorder characterized by global developmental delay, severely impaired speech, intellectual disability, and an increased risk of autism spectrum disorders (ASDs). PMDS is caused by heterozygous deletions of chromosome 22q13.3. Among the genes in the deleted region is SHANK3, which encodes a protein in the postsynaptic density (PSD). Rare mutations in SHANK3 have been associated with idiopathic ASDs, non-syndromic intellectual disability, and schizophrenia. Although SHANK3 is considered to be the most likely candidate gene for the neurological abnormalities in PMDS patients, the cellular and molecular phenotypes associated with this syndrome in human neurons are unknown. We generated induced pluripotent stem (iPS) cells from individuals with PMDS and autism and used them to produce functional neurons. We show that PMDS neurons have reduced SHANK3 expression and major defects in excitatory, but not inhibitory, synaptic transmission. Excitatory synaptic transmission in PMDS neurons can be corrected by restoring SHANK3 expression or by treating neurons with insulin-like growth factor 1 (IGF1). IGF1 treatment promotes formation of mature excitatory synapses that lack SHANK3 but contain PSD95 and N-methyl-D-aspartate (NMDA) receptors with fast deactivation kinetics. Our findings provide direct evidence for a disruption in the ratio of cellular excitation and inhibition in PMDS neurons, and point to a molecular pathway that can be recruited to restore it.

Researchers have developed software that can automatically track and catalog the behavior of up to four mice at once. Mice are often used for autism research because they are easy to manipulate genetically. This new method, which involves using images taken by a heat-sensing camera and a new software algorithm, makes collecting research more efficient.
Autism rates in the United Kingdom appear to have leveled off between the years 2000 and 2010 after a five-fold rate increase in the 1990s. The report, published in the journal BMJ Open, does not have any conclusive answers as to why there was such a dramatic increase in autism diagnosis in the 1990s, but it does state that any link between autism and vaccines has been ruled out. This BMJ Open report is being compared to a report released by the CDC last year that found rates of autism diagnosis in the United States increased 78 percent between 2004 and 2008.
Babies born to women with gestational diabetes tend to be large and go through spells of low blood sugar within their first few days of life. They may also be at an increased risk for autism, reports a study published in the Journal of Autism and Developmental Disorders. The study also found that the risk extends to children born to women who had diabetes prior to pregnancy.
About one-third of people with autism suffer from epilepsy. This overlap suggests that the two disorders may have a common origin a theory borne out by examples of shared genetics. Mutations in GABRB3, a brain receptor linked to autism, are prevalent in severe childhood epilepsy, according to a study published in Nature. The study also found that many of the spontaneous mutations found in children with epilepsy overlap with those linked to autism and fragile X syndrome.
Researchers have optimized the production from stem cells of large numbers of a subtype of neurons involved in cognitive function. These neurons express the chemical messenger glutamate and are implicated in cognitive disorders such as autism. This technique, published in Translational Psychiatry, could generate enough neurons for large-scale screening of drugs.
Research published in the American Journal of Human Genetics found that people with ASDs often have just one copy of certain genes, when typically-developing people have two. This “mis-wiring” could alter the activity of nerve cells in the brain. The study found that the most commonly missing genes were linked to autophagy – a kind of waste-disposal and renewal process for cells. This study was led by Dr. Joseph Buxbaum, who is on ASF’s Scientific Advisory Board.
Some children with autism show unique patterns of brain activation while solving math problems, particularly in a brain region normally used for face processing, suggests a study in Biological Psychiatry. They also seem to use more sophisticated mental strategies to solve these problems than do their typically developing peers, the researchers found.
Researchers have developed a new test that reveals complex repetitive behaviors in BTBR mice, a mouse strain with features resembling those of autism, according to a study published in the Journal of Neuroscience Methods. Repetitive behavior is common in autism, and usually comes in two forms: repetitive actions, such as hand flapping or rocking, and higher-order symptoms, such as an insistence on sameness, or restricted interests. This second form is difficult to produce in mice, but these researchers believe they have been able to do it.
Siblings of children with autism who are later diagnosed with the disorder themselves become more active, less adaptable and less likely to approach others over time, according to a study published in the Journal of Autism and Developmental Disorders. The results reinforce the observation that autism symptoms evolve as children age, the researchers say.
New research from the CDC and published in the journal Developmental Medicine & Child Neurology found significantly high rates of autism among children diagnosed with cerebral palsy. Of the 147,000 children studied, seven percent of the children with cerebral palsy were also diagnosed with autism, compared to a little greater than one percent of kids who have autism in the general population.
Parents of adult children with autism are creating job opportunities for their kids that cater to their strengths. It can be very difficult for someone with autism to find employment that is matched to his or her unique needs, but some organizations, such as Extraordinary Ventures in Chapel Hill, NC are doing just that.
A new nationwide study conducted in Sweden and published in JAMA Psychiatry found there to be no link between celiac disease and autism spectrum disorders. There was, however, some evidence that people who have been diagnosed with autism are more sensitive to gluten, even though they don’t have celiac disease. The design of the study did not allow for a conclusion that gluten sensitivity caused autism, nor vice versa.
The results of a recent study will probably come as no surprise to most parents of children with autism: children with ASDs have more sleep problems than their peers. In fact, between ages 2.5 and 11.5, kids with autism average 43 fewer minutes of sleep per night when compared to their typically-developing peers. The next step is to research how less sleep may play a part in behavior problems.
“In the Driver’s Seat”: Parent Perceptions of Choice in a Participant-Directed Medicaid Waiver Program for Young Children with AutismPublished September 22, 2013 in Journal of Autism and Developmental Disorders
This study investigated families’ experience of choice within a participant-directed Medicaid waiver program for young children with autism. Fourteen parents or grandparents participated in in-depth interviews about their experience of choosing personnel, directing in-home services, and managing the $25,000 annual allocation. Key findings included families’ preference to hire providers with whom they have a prior relationship, parent empowerment and differences of opinion about parents as teachers. Professionals implementing participant directed service models could benefit from understanding the strong value parents’ placed on the personalities and interpersonal skills of providers. Parents’ descriptions of directing rather than merely accepting autism services revealed increased confidence in their ability to choose and manage the multiple components of their children’s HCBS autism waiver program.
The most popular drugs prescribed for autism in some countries often have serious side effects or have not been vetted in robust clinical trials, finds a survey published in the journal Psychopharmacology. Additionally, children with ASDs take more drugs than adults with ASDs. ADHD in children with autism may play a factor in this.
A study by researchers with the UC Davis MIND Institute studied children with chromosome 22q11.2 deletion syndrome, who as a group have a prevalence of autism between 20 and 50 percent according to parent reports. This study found that these children may be getting misdiagnosed because the symptoms of the chromosome 22q11.2 deletion syndrome, including social impairments, are very similar to symptoms of autism.
A new study finds that people with autism often miss facial cues that lead other people to “catch” yawns. Because individuals with autism often avoid looking at other people’s faces, they may not pick up on the cues, such as closed eyes, that would encourage them to yawn. However, when asked to look at someone’s face as they yawn, people with autism do yawn just as often as people without autism.
In a study recently published in the journal Nature, researchers discovered that autism genes are three to four times longer than the average gene expressed in neurons. According to the study, most mutations found in long genes tend to be discounted due to the fact that long genes generally have a higher probability of having a mutation, but the study says researchers think mutations in long genes should be looked at more carefully from now on.

According to a recent study in the journal Intellectual and Developmental Disabilities, most people who work with special-needs children lack basic knowledge about Fragile X syndrome, even though it is the leading cause of inherited intellectual disability. Most people studied did not know many of the symptoms of the syndrome or how best to support children with Fragile X syndrome.
A research group exploring the hypothesis that certain maternal antibodies can impair fetal brains has partnered with a company to develop a test for predicting whether a woman will have a child with autism. The antibodies, they claim, could account for up to a quarter of all autism cases. But other autism scientists are skeptical that the evidence is strong enough to make such a claim, or to consider an autism test based on the antibodies.

In the brain, oxytocin and serotonin work together to make social interactions pleasurable, rewarding, and worth repeating. A new study in the journal Nature shows that in individuals with autism, these rewarding functions may not be occurring properly, making social interaction uncomfortable.
Due to the fact that many people with autism spectrum disorders have difficulty holding eye contact during face to face interaction, these people can miss out on important non-verbal cues during this interaction. The study also found that most people, whether typically- or non-typically developing, have difficulty holding eye contact when thinking, such as if asked to answer a challenging math problem.
Topoisomerases are expressed throughout the developing and adult brain and are mutated in some individuals with autism spectrum disorder (ASD). However, how topoisomerases are mechanistically connected to ASD is unknown. Here we find that topotecan, a topoisomerase 1 (TOP1) inhibitor, dose-dependently reduces the expression of extremely long genes in mouse and human neurons, including nearly all genes that are longer than 200?kilobases. Expression of long genes is also reduced after knockdown of Top1 or Top2b in neurons, highlighting that both enzymes are required for full expression of long genes. By mapping RNA polymerase II density genome-wide in neurons, we found that this length-dependent effect on gene expression was due to impaired transcription elongation. Interestingly, many high-confidence ASD candidate genes are exceptionally long and were reduced in expression after TOP1 inhibition. Our findings suggest that chemicals and genetic mutations that impair topoisomerases could commonly contribute to ASD and other neurodevelopmental disorders.

A study in the Journal of the American Academy of Child and Adolescent Psychiatry notes that young adults with autism spectrum disorders are experiencing particular difficulty in successfully transitioning into employment. Approximately one half of young adults with an ASD have worked for pay outside the home in the first eight years following high school. The study concludes that further research is needed to determine strategies for improving outcomes as these young adults transition into adulthood.
New synthetic biology tools have allowed for great advances in genetic testing of many mutations. This technology known as CRISPR (clustered regularly interspaced short palindromic repeats) allows researchers to create molecular scissors that cut and paste essentially any mutation into the genome of any cell, including a human stem cell.
SFARI’s annual RFA will provide funding for investigators conducting bold, creative and rigorous research into the underlying biology, causes and treatment of autism spectrum disorders. SFARI will consider proposals in diverse areas, including genetics, molecular mechanisms, circuits, anatomy, sensory perception, cognition, behavior, translation and therapeutics.
Autism spectrum disorders (ASD) are increasingly common neurodevelopmental disorders defined clinically by a triad of features including impairment in social interaction, impairment in communication in social situations and restricted and repetitive patterns of behavior and interests, with considerable phenotypic heterogeneity among individuals. Although heritability estimates for ASD are high, conventional genetic-based efforts to identify genes involved in ASD have yielded only few reproducible candidate genes that account for only a small proportion of ASDs. There is mounting evidence to suggest environmental and epigenetic factors play a stronger role in the etiology of ASD than previously thought. To begin to understand the contribution of epigenetics to ASD, we have examined DNA methylation (DNAm) in a pilot study of postmortem brain tissue from 19 autism cases and 21 unrelated controls, among three brain regions including dorsolateral prefrontal cortex, temporal cortex and cerebellum. We measured over 485?000 CpG loci across a diverse set of functionally relevant genomic regions using the Infinium HumanMethylation450 BeadChip and identified four genome-wide significant differentially methylated regions (DMRs) using a bump hunting approach and a permutation-based multiple testing correction method. We replicated 3/4 DMRs identified in our genome-wide screen in a different set of samples and across different brain regions. The DMRs identified in this study represent suggestive evidence for commonly altered methylation sites in ASD and provide several promising new candidate genes.

About one fourth of people with autism are minimally verbal or nonverbal. Early intervention programs have been helping children develop language skills, but researchers say that seemingly unrelated issues such as motor skills and joint attention may hold the key to communication development.
Regulation of visual attention is essential to learning about one’s environment. Children with autism spectrum disorder (ASD) exhibit impairments in regulating their visual attention, but little is known about how such impairments develop over time. This prospective longitudinal study is the first to describe the development of components of visual attention, including engaging, sustaining, and disengaging attention, in infants at high-risk of developing ASD (each with an older sibling with ASD). Non-sibling controls and high-risk infant siblings were filmed at 6, 9, 12, 15, 18, 24, and 36 months of age as they engaged in play with small, easily graspable toys. Duration of time spent looking at toy targets before moving the hand toward the target and the duration of time spent looking at the target after grasp were measured. At 36 months of age, an independent, gold standard diagnostic assessment for ASD was conducted for all participants. As predicted, infant siblings subsequently diagnosed with ASD were distinguished by prolonged latency to disengage (‘sticky attention’) by 12 months of age, and continued to show this characteristic at 15, 18, and 24 months of age. The results are discussed in relation to how the development of visual attention may impact later cognitive outcomes of children diagnosed with ASD.
Creating neurons from stem cells in a lab dish is a popular approach for studying developmental disorders such as autism. For this, researchers begin with stem cells, either taken from postmortem fetal brains or reprogrammed from other cells. They then chemically coax them into becoming neurons. Two new studies suggest that neurons made from stem cells recapitulate the early stages of development, making them good models for disorders such as autism. However, the neurons never fully reach the maturity of neurons found in adult brains.
Although up to 40% of mothers of children with autism report clinically significant depressive symptoms, there has been little attention to the mental health needs of parents. Because most autism services for young children rely on active parental engagement to deliver recommended therapies, maternal functioning directly affects the intensity and quality of therapy that children with autism receive. Developing feasible and acceptable strategies to support the mental health of mothers who care for children with autism has the potential to optimize both maternal and child functioning.
A 2004 study from the Journal of Music Therapy found that music in interventions used with children and teens with ASD can improve social behaviors, increase focus and attention, increase communication attempts (vocalizations, verbalizations, gestures, and vocabulary), reduce anxiety, and improve body awareness and coordination. Read all about it in our newest blog post written by Marcela De Vivo.
Long-Term Outcomes of Parent-Assisted Social Skills Intervention for High-Functioning Children with Autism Spectrum DisordersPublished August 30, 2013 in Autism
This study aims to evaluate the long-term outcome of Children’s Friendship Training, a parent-assisted social skills intervention for children. Prior research has shown Children’s Friendship Training to be superior to wait-list control with maintenance of gains at 3-month follow-up. Participants were families of children diagnosed with autism spectrum disorder who completed Children’s Friendship Training 1-5 years earlier. They were recruited through mail, phone, and email. Information collected included parent and child completed questionnaires and a phone interview. Data were collected on 24 of 52 potential participants (46%). With an average of 35-month follow-up, participants had a mean age of 12.6 years. Results indicated that participants at follow-up were invited on significantly more play dates, showed less play date conflict, improved significantly in parent-reported social skills and problem behaviors, and demonstrated marginally significant decreases in loneliness when compared to pre-Children’s Friendship Training.
Girls with autism tend to have smaller heads and bodies than their typically developing peers, whereas boys with the disorder tend to have average-sized heads and slightly larger bodies, report two recent studies. This shows another way that autism affects males and females differently.
Researchers at UNC have discovered that problems with a key group of enzymes known as topoisomerases can have profound effects on the genetic machinery behind brain development and potentially lead to autism spectrum disorder. Researchers believe this finding represents a great step forward in the search for environmental factors behind autism.
A multisensory room, known as the Snoezelen room, in an Autism Behavioral Center in St. Petersburg, FL is helping individuals with developmental disabilities by allowing them to regulate how much sensory stimulation they experience while in the room. The light up ball pit, patterns of light projected on the wall, and other forms of sensory stimulation are all controlled by a remote given to the individual. There are 1,200 rooms like this in the United States providing a calming experience for people with autism by giving them an escape from an overstimulating world.
For adolescents with autism or other developmental disorders, the transition to adulthood can be especially difficult. A large study in the U.K. is researching this transition period when this group is aging out of pediatric healthcare services and entering the adult system.
Scientists at the Seaver Autism Center at the Icahn School of Medicine at Mount Sinai have received grants from the National Institutes of Health and the Autism Science Foundation to study Insulin-Like Growth Factor-1 (IGF-1), a promising treatment for subtypes of autism. Clinical Director at the Seaver Autism Center, Dr. Alex Kolevzon, says, “IGF-1 has the potential to be effective in treating Phelan-McDermid Syndrome and other types of autism spectrum disorder. We are very pleased that the NIH and the Autism Science Foundation have recognized this by providing us funding to continue our work in bringing this medication to our patients.
Children who have an older sibling with autism are seven times more likely than other kids to be diagnosed with autism themselves, according to a new study from Denmark. A higher-than-average risk was also detected for children who have a half-sibling with ASD, especially if the two children had the same mother.
The FDA has issued a warning against using Hyperbaric Oxygen Therapy (HBOT) in the treatment of autism. HBOT involves breathing oxygen in a pressurized chamber. This treatment has not been cleared by the FDA for the treatment of autism, though there are some places on the internet that falsely claim it has. The FDA urges people to work with their health care professional to determine their best choice for treatment.
Assessment of Global Functioning in Adolescents with ASD: Utility of the Developmental Disability-Child Global Assessment ScalePublished August 21, 2013 in Autism
Assessment of global functioning is an important consideration in treatment outcome research; yet, there is little guidance on its evidence-based assessment for children with autism spectrum disorders. This study investigated the utility and validity of clinician-rated global functioning using the Developmental Disability-Child Global Assessment Scale in a sample of higher functioning adolescents with autism spectrum disorders and comorbid anxiety disorders enrolled in a randomized controlled trial (n = 30). Pretreatment Developmental Disability-Child Global Assessment Scale scores correlated with severity of autism spectrum disorders core symptoms (r = -.388, p = .034), pragmatic communication (r = .407, p = .032), and verbal ability (r = .449, p = .013) and did not correlate with severity of anxiety symptoms or with parent-reported adaptive behavior. Change in Developmental Disability-Child Global Assessment Scale scores during treatment was associated with autism spectrum disorders symptomatic improvement (r = .414, p = .040) and with improved general communication (r = .499, p = .013). Results support the importance of assessing global functioning in addition to symptom change and treatment response in clinical trials.
Researchers have developed a manual called, “A Guide for Emergency Department Personnel: Assessing and Treating Individuals With Autism.” Emergency rooms are often loud and chaotic; this can frighten a person with autism, further hindering his or her communication or sensory skills. This guide aims to teach emergency care givers how to best communicate with and assess autistic patients in these hectic environments.
Autism spectrum disorders (ASD) are characterised by problems with social interaction and communication, as well as repetitive behaviours and limited activities and interests. Selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressants that are sometimes given to reduce anxiety or obsessive?compulsive behaviours. We found nine trials, involving 320 people, which evaluated four SSRIs: fluoxetine, fluvoxamine, fenfluramine and citalopram. Five studies included only children and four studies included only adults. One trial enrolled 149 children, but the other trials were much smaller. We found no trials that evaluated sertraline, paroxetine or escitalopram. There is no evidence to support the use of SSRIs to treat autism in children. There is limited evidence, which is not yet sufficiently robust, to suggest effectiveness of SSRIs in adults with autism. Treatment with an SSRI may cause side effects. Decisions about the use of SSRIs for established clinical indications that may co?occur with autism, such as obsessive?compulsive disorder and depression in adults or children, and anxiety in adults, should be made on a case?by?case basis.
Brain-Reactive IgG Correlates with Autoimmunity in Mothers of a Child with an Autism Spectrum DisorderPublished August 20, 2013 in Molecular Psychiatry
It is believed that in utero environmental factors contribute to autism spectrum disorder (ASD). The goal of this study was to demonstrate, using the largest cohort reported so far, that mothers of an ASD child have an elevated frequency of anti-brain antibodies and to assess whether brain reactivity is associated with an autoimmune diathesis of the mother. We screened plasma of 2431 mothers of an ASD child from Simon Simplex Collection and plasma of 653 unselected women of child-bearing age for anti-brain antibodies using immunohistology on mouse brain. Positive and negative plasma from mothers with an ASD child were analyzed for anti-nuclear antibodies and for autoimmune disorders. Mothers of an ASD child were four times more likely to harbor anti-brain antibodies than unselected women of child-bearing age (10.5 vs 2.6%). A second cohort from The Autism Genetic Resource Exchange with multiplex families displayed an 8.8% prevalence of anti-brain antibodies in the mothers of these families. Fifty-three percent of these mothers with anti-brain antibodies also exhibited anti-nuclear autoantibodies compared with 13.4% of mothers of an ASD child without anti-brain antibodies and 15% of control women of child-bearing age. The analysis of ASD mothers with brain-reactive antibodies also revealed an increased prevalence of autoimmune diseases, especially rheumatoid arthritis and systemic lupus erythematosus. This study provides robust evidence that brain-reactive antibodies are increased in mothers of an ASD child and may be associated with autoimmunity. The current study serves as a benchmark and justification for studying the potential pathogenicity of these antibodies on the developing brain. The detailed characterization of the specificity of these antibodies will provide practical benefits for the management and prevention of this disorder.

Children with autism who are older than 13 years and have low intelligence are at the greatest risk of having epilepsy, says one of the largest epidemiological studies on the issue to date. The presence of epilepsy among the general population is around two percent; the prevalence of epilepsy among people with autism is around thirty percent. This study breaks down occurrence of epilepsy by age, with children ages 13 to 17 having the highest prevalence.
Latino children with autism are being diagnosed less often and later than non-minority children. This new study in Pediatrics shows that this may be due to a language barrier between doctors and patients, along with a lack of dissemination of culturally appropriate ASD materials to Latino families.
Children with autism and average IQs consistently demonstrated superior math skills compared with nonautistic children in the same IQ range, according to a study by researchers at the Stanford University School of Medicine and Lucile Packard Children’s Hospital.
A study from the Houston Methodist Neurological Institute and Erasmus Medical Centre discovered that mothers who do not produce enough of a thyroid hormone, thyroxine, are nearly four times more likely to have a child with autism. In the past, this hormone has been shown to be important in the migration of fetal brain cells during embryo development.
A study posted in JAMA Pediatrics shows an association with induced and augmented labor with an increased risk of autism. Researchers at Duke University Medical Center studied over 625,000 live births, of which 5,500 were documented as having autism. The study adds, While these results are interesting, further investigation is needed to differentiate among potential explanations of the association, including underlying pregnancy conditions requiring the eventual need to induce/augment, the events of labor and delivery…and the specific treatments and dosing used.”
Researchers have recently discovered that two seemingly unrelated conditions, autism and cancer, share an unexpected connection. Some people with autism have specific mutated cancer or tumor genes that scientists believe caused their autism. While this does not apply to all people with autism, just the ones with the mutated gene, it is a very illuminating discovery in the field.
A new database compiles health data from seven countries, greatly expanding sample size for epidemiological autism studies. This project, the International Collaboration for Autism Registry Epidemiology (iCARE), combines data from 80,000 individuals diagnosed with autism from the years 1967 to 2009.
Nelson Freimer and colleagues at UCLA studied a population in an isolated area of Finland where Schizophrenia is more common than in the average Finnish population. In this small group, it was discovered that the presence of a deletion on part of chromosome 22 was much more prevalent than in the rest of the population. This deleted region normally contains an enzyme, TOP3B. This lack of TOP3B is also linked to disruptions that can lead to Fragile X Syndrome, showing there may be a biological link between Fragile X and Schizophrenia. An article about this study can be found here:http://www.newscientist.com/article/dn23995-genetic-discovery-links-autism-and-schizophrenia.html#.UgJvzZJJNf2
An NYU study explored the role of oxytocin in the brain’s ability to filter wanted stimuli from unwanted stimuli. The researchers suggest that the neurohormone, oxytocin, is not only used to reduce unwanted background noise but also plays a key function in strengthening desired signals.
A new study published in JAMA Psychiatry found that men who fathered children at age 50 or older were nearly twice as likely to have a grandchild with autism compared to men who had children at a younger age. The study focused on age-related aspects and sought to control any other variables, such as socioeconomic status.

Play is important to children’s development, and a new study has found the types of play that appeal most to children with ASD: play that provides strong sensory feedback, cause-and-effect results, and repetitive motions. Incorporating this type of play in recreational facilities, after-school programs, and playgrounds encourages inclusion and social interaction with peers.
Dr. Peter Gerhardt of the McCarton School joined us for a live chat. He answered several questions about employment, safety and sexual education in relation to teenagers and adults with autism.

Researchers found that individuals with autism have significantly fewer kinds of bacteria in their intestines. However, there was no relationship found between microbial diversity and severity of GI problems.
Problematic Antibodies Affecting Brain Development During Pregnancy Could Help Explain 1/4 of Cases of AutismPublished July 9, 2013 in Translational Psychiatry
Antibodies found almost exclusively in mothers with children who have autism have a certain anitbody that may be affecting brain development during pregnancy. The same study says that these antibodies could account for nearly 1/4 of all cases of autism.
Maternal Antibodies from Mothers of Children with Autism Alter Brain Growth and Social Behavior Development in the Rhesus MonkeyPublished July 9, 2013 in Translational Psychiatry
Antibodies directed against fetal brain proteins of 37 and 73?kDa molecular weight are found in approximately 12% of mothers who have children with autism spectrum disorder (ASD), but not in mothers of typically developing children. This finding has raised the possibility that these immunoglobulin G (IgG) class antibodies cross the placenta during pregnancy and impact brain development, leading to one form of ASD.

Antibodies directed against fetal brain proteins of 37 and 73?kDa molecular weight are found in approximately 12% of mothers who have children with autism spectrum disorder (ASD), but not in mothers of typically developing children. This finding has raised the possibility that these immunoglobulin G (IgG) class antibodies cross the placenta during pregnancy and impact brain development, leading to one form of ASD. We evaluated the pathogenic potential of these antibodies by using a nonhuman primate model. IgG was isolated from mothers of children with ASD (IgG-ASD) and of typically developing children (IgG-CON). The purified IgG was administered to two groups of female rhesus monkeys (IgG-ASD; n=8 and IgG-CON; n=8) during the first and second trimesters of pregnancy. Another control group of pregnant monkeys (n=8) was untreated. Brain and behavioral development of the offspring were assessed for 2 years. Behavioral differences were first detected when the macaque mothers responded to their IgG-ASD offspring with heightened protectiveness during early development. As they matured, IgG-ASD offspring consistently deviated from species-typical social norms by more frequently approaching familiar peers. The increased approach was not reciprocated and did not lead to sustained social interactions. Even more striking, IgG-ASD offspring displayed inappropriate approach behavior to unfamiliar peers, clearly deviating from normal macaque social behavior. Longitudinal magnetic resonance imaging analyses revealed that male IgG-ASD offspring had enlarged brain volume compared with controls. White matter volume increases appeared to be driving the brain differences in the IgG-ASD offspring and these differences were most pronounced in the frontal lobes.

Controversial Study Suggests That An Ear Muscle In Children with Autism Responds to Lower Decibel Sounds Than Typical ControlsPublished July 3, 2013 in Autism Research and Treatment
A controversial study suggests that an ear muscle in children with autism responds to sounds that are a few decibels lower compared to typically developing children. Some researchers suggest this could be used as a simple clinical biomarker for autism but some scientists disagree.
This study found that most in vitro fertilization (IVF) procedures do not show an increase in the risk of autism. However, it found a small increase in the risk of autism in the most severe forms of male infertility that require surgical sperm retrieval.
This study shows that parents who have children with ASD show significantly higher levels of fatigue when compared to mothers of typically developing children. The study argues the need for interventions that specifically target maternal fatigue.
A UNC comparative efficacy study that compared the LEAP, TEACCH and Non-Model-Specific Special Education Programs found that young children who receive high-quality early intervention benefit developmentally regardless of the treatment model used.
Comparative Efficacy of LEAP, TEACCH and Non-Model-Specific Special Education Programs for Preschoolers with Autism Spectrum DisordersPublished June 28, 2013 in Journal of Autism and Developmental Disorders
LEAP and TEACCH represent two comprehensive treatment models (CTMs) that have been widely used across several decades to educate young children with autism spectrum disorders. The purpose of this quasi-experimental study was to compare high fidelity LEAP (n = 22) and TEACCH (n = 25) classrooms to each other and a control condition (n = 28), in which teachers in high quality special education programs used non-model-specific practices. A total of 198 children were included in data analysis. Across conditions, children’s performances improved over time. This study raises issues of the replication of effects for CTMs, and whether having access to a high quality special education program is as beneficial as access to a specific CTM.
During a brain study, researchers found that individuals with autism have specific areas of hyperconnectivity in the brain. This supports the theory that unique autistic behaviors stem from differences in brain wiring.

A Research Strategy to Discover the Environmental Causes of Autism and Neurodevelopmental DisabilitiesPublished June 7, 2013 in Environmental Health Perspectives
To begin formulation of a systematic strategy for discovery of potentially preventable environmental causes of autism and other NDDs, the Mount Sinai Childrens Environmental Health Center convened a workshop on Exploring the Environmental Causes of Autism and Learning Disabilities. This workshop produced a series of papers by leading researchers and generated a list of 10 chemicals and mixtures widely distributed in the environment that are already suspected of causing developmental neurotoxicity.
A Cambridge study that used brain imaging samples of individuals with autism, led by Dr. Simon Baron-Cohen, found evidence that autism affects sexes differently. The study showed that women who have the condition demonstrate neuroanatomical masculinization, which suggests that women with autism have more masculine brains. Dr. Baron-Cohen argues that this study reinforces that researchers “should not blindly assume that everything found in males with autism applies to females.”News Article: http://www.cambridge-news.co.uk/Education/Universities/Autism-affects-sexes-differently-20130809000647.htm
Two Studies Isolate Specific Brain Circuits That Underlie Compulsive Behaviors Seen in Individuals with OCD and AutismPublished June 7, 2013 in Science
Two studies successfully attempted to shut down and trigger compulsive behaviors in mice by using light to target certain brain circuits. These studies helped isolate the obsessive brain circuits believed to underlie compulsive behaviors in individuals with OCD and autism. 1) http://www.ncbi.nlm.nih.gov/pubmed/237449502) http://www.ncbi.nlm.nih.gov/pubmed/23744948

Working Memory Deficits in High-functioning Adolescents with Autism Spectrum Disorders: Neuropsychological and Neuroimaging correlatePublished June 4, 2013 in Journal of Autism and Developmental Disorders
This new review of neuropsychological and functional neuroimaging studies suggests that system specific problems of spatial working memory are often seen in adolescents with ASD. Additionally, researchers found that “neuroimaging studies indicate a more global working memory processing or connectivity deficiency, rather than a focused deficit in the prefrontal cortex.”
The study found that individuals with ASD had significantly decreased metabolism of the amino acid L-Tryptophan compared to their control group and individuals with other neurodevelopmental disorders. This amino acid could be used as a potential indicator for a simple, early blood test for autism.
Researchers at UCLA observed hyperactive firing rates in the brains of FMR1 knockout mice; mice engineered to have symptoms similar to those in ASD and Fragile X syndrome.
Brain imaging study reveals individuals with autism have a ticker cortex with more folds. This suggests that differences in cognitive abilities of people with autism could be due to unique brain structures.

Brain Imaging Study Shows Decreased Production of Chemical Messenger GABA in Individuals with AutismPublished May 23, 2013 in Neuroimage
A new brain imaging study shows that children with autism have low levels of GABA, a chemical that keeps brain signals in check. This is the third study in two years that supports the theory of decreased production of GABA.
A new report questions the evidence for atypical early brain growth in ASD, suggesting reports of abnormal head circumference (HC) growth may be due to a systematic bias in common HC norms rather than dysregulated early brain growth in ASD. The authors encourage future studies to use comparison data from typically developing and clinical control samples and several growth norms in parallel to avoid bias.
Simons Foundation will host a live DSM-5 roundtable discussion on May 29 at 3pm ET. The panelists, Dr. Thomas Insel, Dr. Cathy Lord and Dr. Helen Tager-Flusberg, will explore the new guidelines’ impact on autism diagnosis as well as on research. Listeners will have a chance to ask the panelists questions during the discussion.

IACC News Update: IACC Recommends Public and Private Health Coverage for Early Behavioral Intervention for Children with ASDPublished March 25, 2013 in IACC
This special report from the Simons Foundation looks at neural connectivity theories of autism.
Recently published in JAMA Psychiatry, this study put forth a new autism risk factor: advanced grandpaternal age. Compared to men who had children between 20 and 24, men who fathered a child at 50+ were 1-2 times more likely to have a grandchild with autism. The findings suggest some autism risk factors can accumulate over generations.
This study examined the relationship between maternal childhood abuse and autism in children in a large population-based sample. Maternal abuse was significantly associated with increased autism risk even after researchers controlled for perinatal risk factors, including gestational diabetes, smoking during pregnancy, preeclampsia, exposure to intimate partner violence and premature birth.
Changes in Prevalence of Parent-reported Autism Spectrum Disorder in School-aged U.S. Children: 2007 to 20112012Published March 20, 2013 in CDC
This report presents data on the prevalence of diagnosed autism spectrum disorder (ASD) as reported by parents of school-aged children (ages 617 years) in 20112012. Results suggest 1 in 50 U.S. children is diagnosed with ASD based on parent report.
With the number of people seeking ASD evaluations in adulthood on the rise, researchers sought to investigate how DSM-5 criteria would fare in a diagnostic clinic for adults with minimal intellectual disability. Compared to ICD-10R and DSM-IV-TR, DSM-5 specificity was good but sensitivity was poor: 44% of adults who met ICD-10R ASD criteria and 22% who met DSM-IV-TR criteria for Asperger syndrome or autistic disorder would not qualify for a DSM-5 ASD diagnosis.
A Quantitative Link between Face Discrimination Deficits and Neuronal Selectivity for Faces in AutismPublished March 15, 2013 in NeuroImage: Clinical
In this fMRI study of adults with ASD, reduced neuronal selectivity for faces was linked to greater behavioral deficits in face recognition.
A mother with two sons with autism helps advance research on neuroligin-4 mutations.
In effort to stimulate more research to better understand ASD trends, ASF President Alison Singer and other stakeholders discuss the increase in ASD prevalence and share their knowledge and opinions.
“If passed, Ava’s Law would require insurance companies to pay for “evidence-driven treatment” — or treatment that’s been scientifically shown to help kids with an autism spectrum disorder. The law would not affect the self-insured plans offered by bigger companies, which cover about 60% of insured people in the state, according to the Georgia Office of Insurance.”
This Wake Forest Study compared the gene expression of gastrointestinal tissue in individuals with autism and compared it to individuals with Crohn’s Disease, ulcerative colitis and a control group. The study showed those with autism had a unique gene expression in their gastrointestinal tissue compared to the other groups studied.
Autism researchers and advocates are concerned about changes to the recruitment strategy of the National Childrens Study, which aims to enroll 100,000 pregnant women, monitor environmental exposures, and examine gene-environment interactions in the women and their children. The changes, which include forgoing door-to-door recruitment, may limit the generalizability of the findings.
Increasing Exposure to Antibody-Stimulating Proteins and Polysaccharides in Vaccines Is Not Associated with Risk of AutismPublished March 6, 2013 in Journal of Pediatrics
This CDC study casts further doubt on the link between autism and vaccines. The study found no connection between the number of vaccines received and autism risk.
Researchers at Kennedy Krieger examined prevalence and predictors of language attainment in severely language-delayed children with ASD. 70% of the sample attained phrase speech and 47% attained fluent speech at or after age 4, indicating that later gains in language are likely in toddlers with severely delayed language. Children with high nonverbal intelligence and high levels of social interest and engagement were most likely to attain language. ASD-related features such as repetitive and sensory behaviors were not associated with language attainment.
In a new study looking at parents of children with ASD, researchers found that parents were less stressed and had improved marital quality with each hour of respite care received.
Is Medication Information for Children with Autism Spectrum Disorder Monitored and Coordinated Across Professionals? Findings from a Teacher SurveyPublished March 1, 2013 in School Mental Health
This study examined school-based medication monitoring in children with ASD. Researchers found that less than half of teachers of medicated students were aware that students were taking medication and no teachers were communicating with prescribing physicians about student behavior and side effects. Since monitoring medication across settings helps physicians assess drug safety and effectiveness, the authors argue for increased communication among professionals.
Metabolic imbalance associated with methylation dysregulation and oxidative damage in children with autism.Published March 1, 2013 in PubMed
Oxidative stress and abnormal DNA methylation have been implicated in the pathophysiology of autism. This investigated the dynamics of an integrated metabolic pathway essential for cellular antioxidant and methylation capacity in children with autism.

Elevated Repetitive Behaviors are Associated with Lower Diurnal Salivary Cortisol Levels in Autism Spectrum DisorderPublished March 1, 2013 in Biological Psychiatry
This pilot study examined the relationship between repetitive behaviors (RBs) and cortisol, a hormone that is released in response to stress, in individuals with ASD. Multiple salivary cortisol samples were taken over three days for 21 children with ASD with high and low levels of RBs. Children in both groups showed the same pattern of cortisol change throughout the day, but the overall cortisol levels in the high RB group were significantly lower, suggesting RBs may work to soothe and decrease stress.
Children with ASD showed increased positive social behaviors in the presence of guinea pigs compared to toys in this new PLOS One study. Specifically, they showed more social approach behaviors (e.g. talking, looking at faces and making tactile contact) and positive affect (e.g. laughing and smiling), and less self-focused behaviors in the presence of animals.
Social stories, an intervention used to define a skill, concept or situation in socially appropriate terms, were used to promote self-regulation techniques in a self-contained preschool classroom. While implementation of self-regulation strategies varied among the children, all showed an increase in desired behaviors with the intervention.
SFARI Gene is an integrated resource for the autism research community. It is a publicly available, curated, web-based, searchable database for autism research. This resource is built on information extracted from the studies on molecular genetics and biology of Autism Spectrum Disorders (ASD). The genetic information includes data from linkage and association studies, cytogenetic abnormalities, and specific mutations associated with ASD.
This interesting preliminary study examined whether typical mice could recognize atypical social behavior in ASD mouse models. Wild-type mouse ‘judges’ preferred to be in chambers with other typical mice rather than socially atypical mice, suggesting that typical mice can distinguish mice displaying autism-like behavior from controls.
Read this new guest post from Theresa Waldron, author of www.healthsnark.com, on the possible link between prenatal folic acid and autism.
This study examined the hypothesis that a protective component of the female sex protects females from autistic behavioral impairment. The results indicate that greater familial risk may be associated with ASD in females, and males may require fewer familial risk factors to reach a similar impairment threshold. The authors hope the study will provide insight into the ASD sex ratio and aid future genetic research.
Oxytocin and Vasopressin in Children and Adolescents With Autism Spectrum Disorders: Sex Differences and Associations With SymptomsPublished February 14, 2013 in Autism Research and Treatment
Following positive results of treatment studies using oxytocin (OT) and evidence of genetic variations in the OT-arginine vasopressin (AVP) pathway in individuals with ASD, a new study from UC Berkeley further examines the involvement of OT and AVP in ASD. Results suggest levels of OT in individuals with ASD may not be as low as previously believed. Moreover, the researchers found significant gender differences, including higher levels of OT in girls and higher levels of AVP in boys.
A review of current research shows that ASD affects females less frequently than males and suggests this difference may be due to several sex-differential genetic and hormonal factors.
Autism Spectrum Disorder Is Associated with Ventricular Enlargement in a Low Birth Weight PopulationPublished February 13, 2013 in Journal of Pediatrics
This new study in the Journal of Pediatrics links ventricular enlargement in the brains of low-birth-weight neonates to ASD.

Beyond Autism: A Baby Siblings Research Consortium Study of High-risk Children at Three Years of AgePublished February 8, 2013 in Journal of the American Academy of Child and Adolescent Psychiatry
This study is the first large-scale examination of ASD behavioral characteristics and developmental functioning in high-risk (HR), non-autistic 3-year-olds with siblings on the spectrum. 79% of HR children were either no different from low-risk children (LR; no known ASD family history) with respect to ASD behavioral severity and developmental functioning, or were developmentally on target with high levels of ASD-related behaviors. 21% of HR children with no ASD diagnosis had an “early manifestation” of a broad autism phenotype: high levels of ASD-related behaviors and/or low levels of verbal and nonverbal functioning. The authors highlight the importance of developmental surveillance and intervention for this HR subset.
Astroglial FMRP-Dependent Translational Down-regulation of mGluR5 Underlies Glutamate Transporter GLT1 Dysregulation in the Fragile X MousePublished February 7, 2013 in Human Molecular Genetics
This paper discusses the role fragile X mental retardation protein (FMRP) plays in protein expression in astrocytes, and suggests that FMRP loss in astrocytes may contribute to the development of fragile X.
Researchers at Virginia Tech examine M-CHAT performance in a very low socio-economic status setting and find it lacks internal consistency across ethnic and educational groups. Caregivers who reported a low maternal educational level or with minority status were more likely to mark items suggestive of autism compared to those with higher maternal education or non-minority status
The age at which a child with autism is diagnosed is related to the particular suite of behavioral symptoms he or she exhibits, according to this study led by an ASF Grantee. Certain diagnostic features, including poor nonverbal communication and repetitive behaviors, were associated with earlier identification of an autism spectrum disorder. Displaying more behavioral features was also associated with earlier diagnosis.For more information about this study, read the guest blog from the lead author here: http://autismsciencefoundation.wordpress.com/2013/04/09/identifying-asd-in-community-settings/
Brief Report: Is Cognitive Rehabilitation Needed in Verbal Adults with Autism? Insights from Initial Enrollment in a Trial of Cognitive Enhancement TherapyPublished February 5, 2013 in Journal of Autism and Developmental Disorders
Early results from this pilot trial of cognitive enhancement therapy (CET) indicate that despite above-average intelligence, verbal adults with ASD can have significantly impaired neurocognition and social cognition. The authors suggest CET, which is designed to remediate both social and non-social deficits through computer-based neurocognitive training, could be useful for cognitive rehabilitation in this population.
Researchers examine parent-child dyads during structured and free play and find that that joint engagement lasts longer when parents engage their child at or slightly above the child’s current level of play. Parents of children with autism often find it difficult to estimate their child’s level, which can result in parents engaging at too high of a level and shortening the interaction.
Feeding Problems and Nutrient Intake in Children with Autism Spectrum Disorders: A Meta-analysis and Comprehensive Review of the LiteraturePublished February 1, 2013 in Journal of Autism and Developmental Disorders
Children with ASD experience more feeding problems compared to their typical peers, such as unusual eating patterns, food rituals and or/refusals, but are not at a greater risk for compromised growth. Researchers attribute this finding to the fact that while children with ASD tend to consume enough food to meet their gross energy needs, their diet often suffers from nutritional deficits.
Producing words by 2 years of age strongly predicted better outcomes in this study of language acquisition and later functioning in children with ASD. The authors suggest that the “acquiring useful language by age 5” criterion for positive prognosis can be updated.
Familiarity Breeds Support: Speech-language Pathologists Perceptions of Bullying of Students with Autism Spectrum DisordersPublished January 31, 2013 in Journal of Communication Disorders

Use of Complementary and Alternative Medicine in Children With Autism and Other Developmental Disabilities: Associations With Ethnicity, Child Comorbid Symptoms, and Parental StressPublished January 30, 2013 in Journal of Child Neurology
Families of children with ASD and other comorbid symptoms, including behavioral problems such as irritability and food allergies, were more likely to use complementary and alternative medicine, and they were more likely to use more types of modalities as compared to families of children with other developmental disabilities.
Not surprisingly, research shows that when the interests of adolescents with ASDs are incorporated into school activities, these students display higher levels of engagement and are more likely to initiate interactions with their typical peers.
Sleep Disruption as a Correlate to Cognitive and Adaptive Behavior Problems in Autism Spectrum DisordersPublished January 28, 2013 in October 1, 2012

Mutations in FAN1, a gene in the 15q13.3 chromosomal region, raise the risk of neuropsychiatric disorders including autism and schizophrenia, according to a new study published in the Proceedings of the National Academy of Sciences. The 15q13.3 chromosomal region is a hotbed of tiny genetic deletions and duplications connected to disorders of brain development.
SFARI: Rare, inherited mutations contribute to a significant proportion of autism cases according to two new studies published in Neuron.
Large national birth cohort study links elevated maternal C-reactive protein (a marker of systemic inflammation) to increased autism risk.
Researchers found that estimates of the number of children with ASD might be lower using the current DSM-5 criteria than using the previous criteria. This study looked at information collected by CDCs Autism and Developmental Disabilities Monitoring (ADDM) Network. This is the first population-based study in the United States to look at what effect the updated ASD criteria in the DSM-5 might have on estimates of the number of children with ASD. One of the advantages of the ADDM Network method is that it does not rely solely on the presence of an ASD diagnosis, but also includes review of records for children who have behaviors consistent with ASDs, even if they do not have a diagnosis. Because of the way the ADDM Network collects data, in the future CDC will be able to use both the previous DSM-IV-TR and the current DSM-5 criteria to estimate the number of children with ASD. CDC will also continue to evaluate the effect of using the DSM-5 on trends in how doctors and other health professionals diagnose ASD and how service providers evaluate and document symptoms as they transition to using the new criteria.
Despite a requirement that insurers start covering behavioral health treatment for individuals and small groups, a new analysis suggests less than half of states plan to include autism therapy.
Childhood Immunization Schedule and Safety: Stakeholder Concerns, Scientific Evidence, and Future StudiesPublished January 16, 2013 in Institute of Medicine of the National Academies
The Institute of Medicine issues a report in response to questions about the safety of the vaccination schedule for children under age six. Thorough examination of the immunization schedule reveals no major concerns associated with adherence to recommended practices.
Some children diagnosed with autism may fall into distinct subgroups based on their symptoms and other diagnoses, researchers report in the January issue of Pediatrics. The three subgroups identified in the study show some overlap in symptoms, but each is characterized by a distinct set of features: seizures, general health problems such as gastrointestinal distress, and psychiatric problems. The analysis relied on the largest database yet, and looked at symptoms over time.
Decreased Spontaneous Attention to Social Scenes in 6-Month-Old Infants Later Diagnosed with Autism Spectrum DisordersPublished January 14, 2013 in Biological Psychiatry
Yale researchers used eye-tracking technology to examine social monitoring skills of infants at high and low risk for autism. Compared to infants who developed typically, six-month olds later diagnosed with ASD looked less at the social scene, which involved a woman engaged in various activities. When they did attend to the social scene, they spent less time viewing the womans face.
MEG study finds diminished long-range and local functional connectivity as individuals with ASD viewed faces. The study challenges the popular assumption that only long-range connectivity is reduced in ASD.

Study Shows Children with Autism only 10 Percent More Likely to be Using Complementary and Alternative MedicinePublished January 11, 2013 in Journal of Developmental and Behavioral Pediatrics
A new study from the Journal of Developmental and Behavioral Pediatrics looked at nearly 600 children with ASD and with developmental delays. 40 percent of the children with autism in the study were using complementary and alternative medicine (CAM). While this may seem like a high percentage, it is only ten percent higher than the rate of nonautistic children in the study using CAM. The most common forms of complementary treatments reported were dietary supplements.

The Association Between Bullying and the Psychological Functioning of Children with Autism Spectrum DisordersPublished January 2, 2013 in PubMed
A new study finds that children with ASD are more likely to be bullied compared to their typical peers. Children with ASD with an additional clinical or educational disorder have an increased risk of being bullied and becoming bullies themselves.
Autism Spectrum Disorder Reclassified: A Second Look at the 1980s Utah/UCLA Autism Epidemiologic StudyPublished January 1, 2013 in Journal of Autism and Developmental Disorders
According to this study, DSM-IV-TR criteria capture more individuals with ASD and intellectual disability than DSM III criteria. The authors examined records from a statewide epidemiological study in the 80s and found that 59% of participants who were considered not autistic in the original study likely were autistic based on current DSM criteria and clinician review methods used in CDC studies.
Anxiety, Sensory Over-responsivity, and Gastrointestinal Problems in Children with Autism Spectrum DisordersPublished January 1, 2013 in Journal of Abnormal Child Psychology
Anxiety, sensory processing problems and gastrointestinal (GI) issues occur frequently in children with ASD. This study examines the relationship between the three and finds that sensory over-responsivity and anxiety are highly associated and linked to GI problems.
This is the first randomized controlled trial demonstrating the efficacy of mindfulness-based therapy for adults with ASD. Participants who received MBT benefited from the therapy, showing less depression, anxiety and rumination, and more positive affect.
Authors of this new review on chelation treatment say, the weakness of the evidence base, the lack of a sound rationale for use of chelation as an ASD treatment, and the potential negative side effects strongly argue against the use of chelation treatment for ASD.
This study analyzes the efficacy and secondary effects of the drugs, Risperidone and Aripipazole.
Anxiety, sensory over-responsivity, and gastrointestinal problems in children with autism spectrum disordersPublished January 1, 2013 in PubMed
Children with autism spectrum disorders (ASD) experience high rates of anxiety, sensory processing problems, and gastrointestinal (GI) problems; however, the associations among these symptoms in children with ASD have not been previously examined. The current study examined bivariate and multivariate relations among anxiety, sensory over-responsivity, and chronic GI problems in a sample of 2,973 children with ASD enrolled in the Autism Treatment Network (ages 2-17 years, 81.6 % male).
Emergency room visits for children with ASD are more likely to be for psychiatric reasons than visits from typically developing children. Having private insurance increases the risk of a psychiatric ER visit for children with ASD, possibly due to the exclusion of ASD as a coverable diagnosis among many private insurance plans.
An estimated 32-92% of parents use complementary/alternative treatments for their children with ASD despite the lack of scientific evidence for the efficacy of these methods. In this article, researchers issue a call for a standardized way to select and evaluate treatments. Barriers to successful treatment, including high costs, limited availability, parental compliance and poor recommendations from professionals are discussed.
The prevalence of physical aggression was 53% across a sample of nearly 1600 children and adolescents with ASD. Girls and boys were equally likely to display aggressive behaviors. The researchers suggest sleep problems, self-injury and sensory problems may increase risk for physical aggression, and argue for better identification and treatment of these conditions.

The Autism Sequencing Consortium: Large-Scale, High-Throughput Sequencing in Autism Spectrum DisordersPublished December 20, 2012 in Neuron
Dr. Joseph Buxbaum and team discuss the current state of ASD gene discovery and the benefits of a genomic technology called high-throughput sequencing.
ASF SAB member Dr. Joe Buxbaum on his new gene discoveries using high-throughput sequencing: “By identifying the many genetic roots of this disorder, we can better understand its biology, which in turn will allow us to develop more tailored treatments for individuals. It is a transformative time for genetic research in autism.”
Telehealth interventions, the delivery of specialized services through communication technologies, may be a viable option for families of young children with ASD who have limited access to intervention services.
AAP reverses position on thimerosal, saying if it knew in 1999 what it knows now about thimerosol it would NOT have issued the statement calling for thimerosol to be removed from vaccines that resulted in panic. “Studies looking for harms from thimerosal-containing vaccine failed to find such associations. The consistent lack of evidence of any harm from thimerosal in vaccines formed the basis of the AAP’s reversal of its 1999 stance, and Cooper and Katz suggested that the academy would not have issued the original statement with that knowledge in-hand.”
Portable Intermodal Preferential Looking (IPL): Investigating Language Comprehension in Typically Developing Toddlers and Young Children with Autism.Published December 14, 2012 in PubMed
Researchers at UCONN have developed an intermodel preferential looking assessment that relies on the child’s attention, rather than verbal or gestural responses, to evaluate language comprehension.
Researchers link Fragile X syndrome protein to 93 genes that have been implicated in ASD. Lead investigator says the findings may lead to more detailed genetic tests.
