Deadline for comments on US Preventative Services Task Force screening of autism in young children

Filed under: , , , , ,

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.

New Diagnostic Tool for Adults with Autism

Published December 9, 2013

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.

Beyond Autism: A Baby Siblings Research Consortium Study of High-risk Children at Three Years of Age

Published 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.

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.

Newly Published Genetics/Brain Tissue Study Will Help Refine the Search for Specific Early Genetic Markers of Risk of Autism in Babies and Toddlers

Published March 22, 2012 in PLoS Genetics

A new study of autism published today in PLoS Genetics has discovered abnormal gene activity and gene deletions in the same brain region that also has a 67% overabundance of brain cells. This region the prefrontal cortexis involved in social, emotional, communication and language skills. The finding brings new understanding of what early genetic abnormalities lead to excess brain cells and to the abnormal brain wiring that cause core symptoms in autism. Importantly, the study also shows that gene activity abnormalities in autism change across the lifespan.

Serotonin Plays Role in Many Autism Cases, Studies Confirm

Published February 24, 2011 in Science Daily

Georgianna Gould, Ph.D., research assistant professor of physiology in the Graduate School of Biomedical Sciences, is eyeing the role that serotonin plays in autism spectrum disorders. Serotonin is known for giving a sense of well-being and happiness. It is a neurotransmitter, a chemical that acts like a radio tower in the brain conveying signals among cells called neurons. Thirty percent of autism cases may have a serotonin component. In a recent paper in the Journal of Neurochemistry, Dr. Gould and colleagues showed that a medication called buspirone improved the social behaviors of mice. Buspirone is approved by the U.S. Food and Drug Administration for use in adults as an anti-anxiety and antidepressant adjuvant medication.

Do Handwriting Problems with Autistic Children Continue into their Teen Years?

Published November 16, 2010 in Medical News Today

A new study suggests that the handwriting problems that affect children with autism are likely to continue into their teenage years. The research found that the teenagers with autism earned 167 points out of 204 total possible points on the handwriting assessment, compared to the 183 points scored by teens in the group without autism. These results showed statistical significance in the study. The teenagers with autism also had motor skill impairments.

Researchers Connect APC Protein to Autism and Mental Retardation

Published August 24, 2010 in Medical News Today

A clue to the causes of autism and mental retardation lies in the synapse, the tiny intercellular junction that rapidly transfers information from one neuron to the next. According to neuroscientists at Tufts University School of Medicine, with students from the Sackler School of Graduate Biomedical Sciences at Tufts, a protein called APC (adenomatous polyposis coli) plays a key role in synapse maturation, and APC dysfunction prevents the synapse function required for typical learning and memory.

Researchers Find Predictors of Autism That Can Lead to Infant Diagnosis

Published August 5, 2010 in S.I. Live

Certain behaviors seen in infants as young as 1-month-old may be predictors of autism spectrum disorders, according to new research by scientists at the Institute for Basic Research and Developmental Disabilities, Willowbrook.At 1 month, children with the ASD diagnosis were more likely to have asymmetrical visual tracking and arm tone deficits. By 4 months, they were more attracted to higher levels of visual stimulation, much like younger infants. Between 7 and 10 months, the children with ASD showed major declines in mental and motor performance.

Blinking Could Detect Autism

Published May 21, 2010 in SFARI

The researchers tracked eye movements and blinks in 41 2-year-olds with autism and 52 healthy controls while the children watched a short movie of two toddlers on a playground. Both groups on average blinked about five times per minute. But they differed significantly in how their blinking lined up with the content of the movie.Healthy toddlers refrained from blinking as they watched scenes with high emotional content, such as when the toddler-actors fought about a toy. Toddlers with autism, in contrast, were just as likely to blink during emotional scenes as during dull ones.

Studies Link Infertility to Autism

Published May 20, 2010 in Time

A study, conducted by a team at the Harvard School of Public Health, found that autism was nearly twice as common among the children of women who were treated with the ovulation-inducing drug Clomid and other similar drugs than women who did not suffer from infertility, and the link persisted even after researchers accounted for the women’s age. Moreover, the association between fertility drugs and autism appeared to strengthen with exposure: the longer women reported being treated for infertility, the higher the chances their child had an autism spectrum disorder (ASD).

New Research Raises Hope that Autism Effects May Be Reversible

Published April 22, 2010 in Medical News Today

A new study by researchers at The George Washington University School of Medicine and Health Sciences’ Department of Biochemistry and Molecular Biology raises hope that autism may be more easily diagnosed and that its effects may be more reversible than previously thought. Researchers have identified potentially removable chemical tags (called “methyl groups”) on specific genes of autistic individuals that led to gene silencing. They also observed these changes in cells derived from blood, opening the way to molecular screening for autism using a blood test.

First Direct Recording Made of Mirror Neurons in Human Brain

Published April 13, 2010 in Science Daily

Neuroscientists believe this “mirroring” is the mechanism by which we can “read” the minds of others and empathize with them. It’s how we “feel” someone’s pain, how we discern a grimace from a grin, a smirk from a smile. Problem was, there was no proof that mirror neurons existed — only suspicion and indirect evidence. Dr. Itzhak Fried, a UCLA professor of neurosurgery and of psychiatry and biobehavioral sciences, Roy Mukamel, a postdoctoral fellow in Fried’s lab, and their colleagues have for the first time made a direct recording of mirror neurons in the human brain.It’s suspected that dysfunction of these mirror cells might be involved in disorders such as autism, where the clinical signs can include difficulties with verbal and nonverbal communication, imitation and having empathy for others. So gaining a better understanding of the mirror neuron system might help devise strategies for treatment of this disorder.

Children With Autistic Traits Remain Undiagnosed

Published March 22, 2010 in Science Daily

There has been a major increase in the incidence of autism over the last twenty years. While people have differing opinions as to why this is (environment, vaccines, mother’s age, better diagnostic practice, more awareness etc.) there are still many children who have autistic traits that are never diagnosed clinically. Therefore, they do not receive the support they need through educational or health services.

New CDC Report on Prevalence of Autism Spectrum Disorders

Published December 18, 2009 in CDC- MMWR Surveillance Studies

In 2006, on average, approximately 1% or one child in every 110 in the 11 ADDM sites was classified as having an ASD. The average prevalence of ASDs identified among children aged 8 years increased 57% in 10 sites from the 2002 to the 2006 ADDM surveillance year. Although improved ascertainment accounts for some of the prevalence increases documented in the ADDM sites, a true increase in the risk for children to develop ASD symptoms cannot be ruled out. On average, although delays in identification persisted, ASDs were being diagnosed by community professionals at earlier ages in 2006 than in 2002.
