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.
Short questionnaires that parents can fill out at a pediatrician’s office flag early signs of autism in infants and toddlers well before the disorder is usually diagnosed, according to two new studies.
Children with autism who participate in a specialized drama program show improvements in face identification and theory of mind, the ability to infer what others are thinking, according to a study published in the April issue of the Journal of Autism and Developmental Disorders.

A delayed response to unexpected changes in sound frequency is a marker for language impairment and autism, according to a study published in March in Biological Psychiatry.
A powerful cell that dampens electrical signaling in the brain could help unravel the disrupted brain wiring seen in people with autism, according to results presented yesterday at the Wiring the Brain meeting in Ireland.
Small duplications or deletions of DNA regions — called micro-copy number variations — may not lead directly to disease, but could raise the risk of autism when combined with other mutations, according to a study published in March in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics.
There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.
