[Autism, infantile: diagnostic aspects].

Autism is a rare disorder, whose frequency varies according to research from 0.7 to 4.5 per 10,000. The results of 40 children examined in the Out-patient Rehabilitation Union for Autistic Children showed that according to the DSM-III-R criteria 3 children suffered from autism. The authors suggest that the DSM-III-R criteria are either not known to the diagnosticians or are not used in the diagnosis.
