Autistic disorders have become increasingly known as pervasive developmental disorders since the 1980s. They have been recently called autism spectrum disorder mostly by the American Psychiatric Association.They include five chronic disorders marked by early impairment in socialization, communication, and behavior. There is no curative therapy or therapies for autistic disorders, and they continue to be regarded as life long disorders. The aim of this paper is to describe our extensive experiences with treatment of autistic disorders with emphasis on the possibility of curing these disorders with a new therapeutic approach. Marked improvement or disappearance of autistic features in these disorders has not been reported with any therapy before.
