Genetic screening of children with autism is critical to designing more effective interventions and treatment, says a pediatrician.
Diagnosing autism is an evolving science but a crucial first step to understanding the disorder.
Individuals with intellectual disability are more likely than controls to have harmful mutations in autism candidate genes, according to a study published 11 March in the American Journal of Human Genetics.
Teenage boys with Asperger syndrome with higher-than-average scores on tests of abstract reasoning fare worse than controls on short-term memory and ability to filter out distractions.
Long bundles of neurons that connect key regions in the brain develop abnormally in the first year of life in children with autism, according to new findings presented Friday at the International Meeting for Autism Research in San Diego.
A new analysis of children with autism and their unaffected parents provides the best evidence to date that mutations in multiple genes may work together to cause autism and related disorders.
Large studies on the epidemiology and genetics of epilepsy and autism have uncovered commonalities between the two disorders. But scientists are only beginning to untangle the biological roots of the overlap.
Good mouse models of autism, and accurate tests to assay their phenotypes, are key to both narrowing down a cause and developing effective treatments, argues expert Jacqueline Crawley.
Smaller-than-normal volume in several brain regions, including a region involved in relaying motor signals, could be a marker for repetitive behavior in 3-year-old children, according to a study published 7 April in Autism Research.
Two large studies published in the past two months have found that traits linked to autism are widely distributed in the general population. Although about 1 in 100 children is diagnosed with autism, up to 30 percent of people may have at least one of the traits associated with the disorder.
