Autism is complex developmental disorder of brain function causes impaired social interaction, problems with verbal and nonverbal communication, and unusual or severely limited activities and interests. Autism significantly impairs a child’s ability to communicate and socialize with others. Autism is not a mental illness or a behavior problem, and it is not caused by bad parenting.
Symptoms of autism usually appear during the first three years of childhood and continue throughout life. Children with autism have little interest in friends or social interactions, often failing to develop verbal and nonverbal communication skills. Although there is no cure, appropriate early educational intervention may improve social development and reduce undesirable behaviors.
The cause of autism is not known. Research suggests that autism is a genetic condition. It is believed that several genes are involved in the development of autism. Children with autism should be trained in functional living skills at the earliest possible age. Learning to cross a street, to buy something in a store, or ask for help are critical skills and may be hard even for those with average intelligence. Training is aimed at boosting a person’s independence and providing opportunity for personal choice and freedom.
