Children with autism are known to have strange rhythms and pitch to their speech, and they speak less often or for shorter periods. Based on these patterns, a company promises to accurately identify children with the disorder.

Attention deficit hyperactivity disorder (ADHD) and autism may have more in common than childhood onset and a few similar symptoms. New research suggests the conditions share genetic roots.

At 6 months of age, babies who will later develop autism begin to lose some of their social skills and continue to regress until age 3, according to a study published in the Journal of the American Academy of Child & Adolescent Psychiatry.

Scientists have created machines to detect distinctive speech patterns in children with autism that go unnoticed by the naked ear.

New pharmacological and behavioral interventions can reverse characteristics of autism in a mouse model of the disorder, according to unpublished results presented in poster sessions today at the Society for Neuroscience meeting.

Two research groups have achieved an elusive goal: producing mouse models that show distinct social and behavioral abnormalities reminiscent of autism.
