Tourette-like disorder in Asperger's syndrome

Abstract

An eight-year-old boy with Asperger's syndrome was given haloperidol to control agitation and aggressive outbursts. Withdrawal of the drug after two years was followed by Tourette-like symptoms. Subsequently neither haloperidol nor a second antipsychotic drug altered the core features of Asperger's syndrome, despite suppressing the movement disorder. His first exposure to neuroleptics was in utero.
