[Autism in children. Speech, behavior and motor activity point to diagnosis]

Austistic disorders characteristically involve specific impairments of social skills, of the language and of stereotyped body movements. L Kanner and H. Asperger were the first to describe these psychopathologic features, which still form the core of the diagnostic criteria of contemporary psychiatric classification systems, ICD-10 and DSM-IV, in the category pervasive developmental disorders. Useful diagnostic tools have been developed to establish the clinical diagnosis. The results of research point to a predominantly genetic pathogenesis involving a complex interaction of multiple genes. While no causal treatments are available for these heterogenic disorders, there are many therapeutic concepts. Although some treatments may achieve significant improvements, autistic disorders usually mean a lifelong individual impairment.
