[Characteristics of the Tourette syndrome-like disorders in various mental disorders].

Fifty-four children with Gilles de la Tourette's syndrome were examined from 1987 to 1989. In 11 of them, Gilles de la Tourette-like disorders occurred within the framework of schizophrenia and in 6, of encephalopathy. The characteristic features of hyperkinesis associated with those conditions and their differences from the routine syndrome are depicted. The typology of Gilles de la Tourette's syndrome reflecting its clinical pleomorphism is suggested.
