We studied the effect of olanzapine (1 to 15 mg/d) in 15 nondemented parkinsonian patients with drug-induced psychosis. Psychotic symptoms decreased significantly during treatment, and there was no worsening of extrapyramidal symptoms. These results suggest that olanzapine is a well-tolerated and effective treatment for drug-induced psychosis in nondemented patients with Parkinson's disease.

    ABSTRACT: With increasing longevity, greater numbers of patients with schizophrenia and delusional disorder will be surviving into advanced age. Antipsychotics form the core of the treatment for both of these psychotic disorders. Treatment of elderly patients with antipsychotics is, however, complicated by a much higher risk of adverse effects such as tardive dyskinesia. More is known about treating patients with schizophrenia than those with delusional disorder. The introduction of newer atypical antipsychotics may herald a new era in the pharmacotherapy of elderly psychotic patients. Nonetheless, judicious dosing is essential in the geriatric population. We discuss the benefits and limitations of the main forms of treatment.

    ABSTRACT: Clozapine, the only commercially available atypical neuroleptic, is approved for the treatment of schizophrenic patients who are unresponsive to or intolerant of typical neuroleptics. It has an unusual pharmacologic profile compared with standard neuroleptics, and it follows that clinical response to this drug is also different. It has shattered the notion that a drug must be capable of inducing or worsening parkinsonism to be a potent antipsychotic. Based on these findings, it is being used increasingly by neurologists for psychiatric and nonpsychiatric problems in patients with movement disorders. The most common use for clozapine among neurologists is in the management of drug-induced psychosis in Parkinson's disease (PD). This problem has been a source of increased morbidity and mortality in PD because of a lack of adequate therapeutic intervention. At this time, because of success in numerous open trials, with improvement of > 80% of patients, clozapine therapy for psychosis in PD is becoming the standard of care. It also appears to be of value in the management of some motor features of PD, including tremors and dyskinesia and possibly even sensory symptoms such as akathisia and pain. The literature also suggests that clozapine may be of potential benefit in hyperkinetic movement disorders including essential tremor, Huntington's disease, and tardive dyskinesia. We review the current data concerning the use of clozapine in patients with these movement disorders and others.
