title: Stereotyped behaviors or punding after quetiapine administration in Parkinson's disease.
abstract: Quetiapine has been suggested to be useful for the treatment of psychosis in patients with Parkinson's disease without prominent deterioration of motor functions. We present two patients with Parkinson's disease in whom administration of quetiapine for drug-induced psychosis caused characteristic stereotyped behaviors or punding. Since stereotyped behaviors are usually associated with excessive dopaminergic activity, it is clinically important to note that stereotyped behaviors or punding may be induced by an atypical antipsychotic drug for the treatment of psychosis in patients with Parkinson's disease.
