What is Autism?

Autism is classified as one of the pervasive developmental disorders of the brain. It is not a disease. People with classical autism show three types of symptoms: impaired social interaction, problems with verbal and nonverbal communication, and unusual or severely limited activities and interests. These symptoms can vary in severity.

In addition, people with autism often have abnormal responses to sounds, touch, or other sensory stimulation. Symptoms usually appear during the first three years of childhood and continue through life.

Researchers have identified a number of genes that play a role in the disorder. In some children, environmental factors also may play a role.

Studies of people with autism have found abnormalities in several regions of the brain which suggest that autism results from a disruption of early fetal brain development.

Autism affects an estimated 10 to 20 of every 10,000 people, depending on diagnostic criteria used, and strikes males about four times more often than females.

Is there any treatment?

There is currently no cure for autism, but appropriate treatment may foster relatively normal development and reduce undesirable behaviors.

Educational/behavioral therapies and drug interventions are designed to remedy specific symptoms. Educational/behavioral therapies emphasize highly structured and often intensive skill-oriented training.

Doctors also may prescribe a variety of drugs to reduce symptoms of autism Other interventions are available, but few, if any, scientific studies support their use.

What is the prognosis?

People with autism have normal life expectancies. Symptoms in many children improve with intervention or as the children age. Some people with autism eventually lead normal or near-normal lives.

Adolescence can worsen behavior problems in some children, and parents should be ready to adjust treatment for the child's changing needs. About a third of children with autistic spectrum disorders eventually develop epilepsy. The risk is highest in children with severe cognitive impairment and motor deficits.
