[Autism spectrum disorders in children and adolescents].

Childhood autism, Asperger's syndrome and atypical autism together make up autism spectrum disorders (ASDs) with a prevalence of 0.6-0.7%. These disorders are defined by qualitative impairments in social interaction, qualitative abnormalities in communication, and by restricted, stereotyped, repetitive patterns of behaviour, interests and activities. Many children or adolescents with ASDs have sensory abnormalities, neurological disorders and additional disabilities of vision, hearing or ambulation. Psychiatric co-morbidity is common. Diagnostics and rehabilitation are implemented in multi-professional collaboration. Early recognition makes up the basis for early intervention that improves the prognosis. Screening of these disorders in well-baby clinics is being developed.
