Treatment of schizophrenia and delusional disorder in the elderly

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.
