The brains of children with autism show a delayed response to sound, which may lead to their language problems.

There is no evidence to support the idea of autism-specific gut problems, according to a review published Monday in Pediatrics.

Guoping Feng’s perseverance has proven a boon to the hundreds of neuroscientists who rely on his most celebrated scientific achievement: two dozen mouse strains engineered to have brightly colored brain cells. By creating the first robust mouse model of obsessive-compulsive disorder, Feng has also found a way to study repetitive behaviors, one of the three core characteristics of autism.

Astropolis, a dynamic video game, allows for the unprecedented testing of children with autism on a variety of cognitive skills, all at once, without the artificial, boring and anxiety-ridden setup of a typical psychology lab.

Scientists have for the first time found direct evidence that defects in the GABA receptor sometimes give rise to autism, according to research published 24 November in Molecular Psychiatry.

The pupils of children with autism contract more slowly in response to flashes of light than those of their healthy peers, according to findings published in the November issue of the Journal of Autism and Developmental Disorders.

Using new genetic screening technology, a few research groups are finding that a surprisingly large number of children with autism — at least five percent — have an underlying problem with their mitochondria, the energy factories of the cell.

In the spirit of Thanksgiving, those dealing with autism received some welcome news last week: The U.S. Food and Drug Administration approved Abilify (aripiprazole) as a treatment for autism-related irritability.

There are clinical, anatomical and genetic overlaps between autism and certain rare developmental disorders of the cerebellum, and these disorders may help scientists understand autism, according to several studies published in the past year.

Studies on younger siblings of children with autism are finding that during tests of sensory or perceptual processing, these baby sibs show abnormally fast brain responses, rather than a delay.
