In addition, infections to the central nervous system of a fetus could lead to autism. There is no known cure for autism, but there are many treatments and interventions. Core interventions are educational and take place in regular classrooms, special classrooms in a regular school, special schools, or institutions. These interventions focus on academic or vocational skills and promote socialization and communication skills. The children in these interventions benefit from small-group instruction with many adults.
Parent involvement is critical.
Improvements in children with autism can be linked to training of parents in behavior therapy. Behavior therapy focuses on increasing positive behaviors. The communicative and social interactions are designed to suit the child's needs. Children showed dramatic improvements in developmental progress, I.Q. gain, and reduction of antisocial behavior. Another intervention is speech and language therapy.
