Watching for Early Signs of Autism in Babies
Children with autism have difficulty with social skills and communication. They may seem different, have repetitive behaviors and have abnormally intense interests. A widely used medical guide will now list autism under a new definition and name, "autism spectrum disorder." The changes will appear in the Diagnostic and Statistical Manual of Mental Disorders, to be published in May. The "spectrum" represents a group of developmental brain disorders, ranging from mild to severely disabling. A milder form called Asperger's syndrome will no longer be listed as a separate disorder with its own name. Autism is more common in boys than girls. What causes autism is not clear. Scientists are studying genes and possible environmental influences. Doctors usually cannot confirm a diagnosis of autism until a child is about three years old.
