Definition
Autistic disorder (sometimes called autism or classical ASD) is the most common condition in a group of developmental disorders known as the autism spectrum disorders (ASDs).
Autistic children have difficulties with social interaction, display problems with verbal and nonverbal communication, and exhibit repetitive behaviors or narrow, obsessive interests. These behaviors can range in impact from mild to disabling. Autism varies widely in its severity and symptoms and may go unrecognized, especially in mildly affected children or when more debilitating handicaps mask it. Scientists aren’t certain what causes autism, but it’s likely that both genetics and environment play a role.
Autism spectrum disorder is diagnosed based on symptoms, signs, and other testing according to the Diagnostic and Statistical Manual V, a guide created by the American Psychiatric Association to diagnose mental disorders. Children should be screened for developmental delays during periodic checkups and specifically for autism at 18- and 24-month well child visits.
For many children, autism symptoms improve with treatment and with age. Some children with autism grow up to lead normal or near-normal lives. Children whose language skills regress early in life, usually before the age of 3, appear to be at risk of developing epilepsy or seizure-like brain activity. During adolescence, some children with autism may become depressed or experience behavioral problems.
Parents of these children should be ready to adjust treatment for their child as needed. People with an ASD usually continue to need services and support as they get older but many are able to work successfully and live independently or within a supportive environment.
There is no cure for autism. Therapies and behavioral interventions are designed to remedy specific symptoms and can bring about substantial improvement. The ideal treatment plan coordinates therapies and interventions that meet the specific needs of individual children. Treatment options include educational/behavioral interventions, medications, and other therapies. Most professionals agree that the earlier the intervention, the better.
