Use of atypical antipsychotics in neurodegenerative diseases

Abstract

Behavioral and psychotic disturbances are common symptoms in neurodegenerative disorders, and can lead to caregiver stress, nursing home placement and mortality. There is an expanding literature evaluating the effects of atypical antipsychotic (AA) drugs for treating these problems. The results in both primary dementias and Parkinson‘s disease suggest that not all AA drugs are equal in terms of efficacy or safety. Furthermore, Parkinsonian and other side effects of the AAs are important to consider when evaluating outcomes. The recent US FDA warning of increased mortality has increased uncertainty in using these drugs. This article reviews the AAs and their use in Parkinson‘s disease, dementia with Lewy bodies, Alzheimer‘s disease and other associated dementias.
