This paper describes the care and social treatment for parent(s) and child with Asperger syndrome. The children with Asperger syndrome are not easily distinguished from children without Asperger syndrome. The diagnosis can be varied depending on perspectives. They are more likely to receive inappropriate intervention due to lack of understanding. They are more likely to develop emotional and conduct problems secondarily. Because their disorders cannot be seen clearly, their difficulties are not identified. It seems that parent(s) and child with Asperger syndrome are hurt by this problem. It is difficult to operate parents' association and self-help group. They should learn it about one's diagnosis. While having a difference, an effort to live together is demanded.
