Around us, at least 6 out of every 1000 people are autistic. The etiology of autism is unclear. It is currently believed that autism is due to a neurodevelopmental disorder caused by external environmental factors (infection, intrauterine or perinatal injury, etc.) acting on individuals with a genetic susceptibility to autism. Interpersonal and communication difficulties, as well as narrow interests and repetitive habitual behaviors are the core symptoms of autism, which are often accompanied by a variety of behavioral problems such as hyperactivity, self-injury, aggression, fear, and disruption of routine. Behavior modification therapy is the most effective treatment available.
