Predictors of Phrase and Fluent Speech in Children With Autism and Severe Language Delay

Published March 4, 2013 in Pediatrics

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.

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.

The Modified Checklist for Autism in Toddlers: Reliability in a Diverse Rural American Sample

Published February 6, 2013 in Journal of Autism and Developmental Disorders

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

Parent-child Interactions in Autism: Characteristics of Play

Published February 4, 2013 in Autism

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.

Autism Developmental Delay Begins After 6 Months of Age

Published October 31, 2012 in Psych Central

A large, prospective study found that children with and without ASD were developmentally similar at 6 months based on clinical tests. Lead author Dr. Rebecca Landa reported, for those children who went on to develop autism, the earliest signs of atypical development were non-specific to autism, such as general communication or motor delay.

Effects of a Brief Early Start Denver Model (ESDM)-Based Parent Intervention on Toddlers at Risk for Autism Spectrum Disorders: A Randomized Controlled Trial

Published October 1, 2012 in Journal of the American Academy of Child & Adolescent Psychiatry

Contrary to their hypothesis, Sally Rogers and colleagues found that toddlers with ASD in a brief, parent-delivered ESDM program did not make greater gains or show reduced core ASD symptoms compared to autistic toddlers in a community ESDM program. Study strongly suggests number of intervention hours and younger age at initiation are key to maximizing intervention benefits, even for 1 and 2 year olds. Authors say, the wait and see approach to early ASD must be replaced by an act now mentality.

Blood-based Gene Expression Signatures of Infants and Toddlers with Autism.

Published September 1, 2012 in Journal of the American Academy of Child and Adolescent Psychiatry

“OBJECTIVE: Autism spectrum disorders (ASDs) are highly heritable neurodevelopmental disorders that onset clinically during the first years of life. ASD risk biomarkers expressed early in life could significantly impact diagnosis and treatment, but no transcriptome-wide biomarker classifiers derived from fresh blood samples from children with autism have yet emerged.RESULTS: Potential ASD biomarkers were discovered in one-half of the sample and used to build a classifier, with high diagnostic accuracy in the remaining half of the sample.”

Differences in Autism Symptoms Between Minority and Non-Minority Toddlers

Published September 1, 2012 in Journal of Autism and Developmental Disorders

Researchers discover gross motor, communication and language score differences between minority and non-minority toddlers with ASD. The authors suggest that due to cultural differences, minority parents may not seek intervention services until more significant delays are present. Methods to improve early identification in these groups are discussed.

Supplemental Material Blood-Based Gene Expression Signatures of Infants and Toddlers With Autism

Published September 1, 2012 in Journal of the American Academy of Child & Adolescent Psychiatry

Dr. Eric Courchesne recently published his work he previewed at this year’s IMFAR in the “Journal of the American Academy of Child & Adolescent Psychiatry.”The mRNA expression abnormalities reliably observed in peripheral blood mononuclear cells, which are safely and easily assayed in infants, offer the first potential peripheral bloodbased, early biomarker panel of risk for autism in infants and toddlers. Future work should verify these biomarkers and evaluate whether they may also serve as indirect indices of deviant molecular neural mechanisms in autism.

The First Year Inventory: A Longitudinal Follow-up of 12-month-old to 3-year-old Children

Published August 2, 2012 in Autism

“The First Year Inventory is a parent-report measure designed to identify 12-month-old infants at risk for autism spectrum disorder. First Year Inventory taps behaviors that indicate risk in the developmental domains of sensory-regulatory and social-communication functioning. This longitudinal study is a follow-up of 699 children at 3 years of age from a community sample whose parents completed the First Year Inventory when their children were 12 months old. Parents of all 699 children completed the Social Responsiveness Scale-Preschool version and the Developmental Concerns Questionnaire to determine age 3 developmental outcomes. In addition, children deemed at risk for autism spectrum disorder based on liberal cut points on the First Year Inventory, Social Responsiveness Scale-Preschool, and/or Developmental Concerns Questionnaire were invited for in-person diagnostic evaluations. We found 9 children who had a confirmed diagnosis of autism spectrum disorder from the sample of 699. Receiver operating characteristic analyses determined that a two-domain cutoff score yielded optimal classification of children: 31% of those meeting algorithm cutoffs had autism spectrum disorder and 85% had a developmental disability or concern by age 3. These results suggest that the First Year Inventory is a promising tool for identifying 12-month-old infants who are at risk for an eventual diagnosis of autism spectrum disorder.”

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.

Autism Not Diagnosed As Early In Minority Children

Published February 28, 2012 in NPR

Early diagnosis is considered key for autism, but minority children tend to be diagnosed later than white children. Some new work is beginning to try to uncover why and to raise awareness of the warning signs so more parents know they can seek help even for a toddler.

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.
