AUTISM
What is Autism?
Autism is classified as one of the pervasive developmental disorders of the brain. It is not a disease.
Recent studies strongly suggest that some people have a genetic predisposition to autism. Researchers are looking for clues about which genes contribute to this increased susceptibility. 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.What are the Symptoms of Autism?
People with classical autism show three types of symptoms:
-
impaired social interaction
-
problems with verbal and nonverbal communication
-
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.
What is the Treatment for Autism?
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.
