Neuropsychiatric symptoms as a predictor of caregiver burden in Alzheimer's disease.

Abstract

Increased caregiver burden was related to increased levels of patient behavioral disturbance. Of these symptoms, hallucinations, unusual (motor) behavior, and abnormal behavior at nighttime were the most significant. No correlation with neuropsychiatric symptoms such as apathy and depression was found. This may have relevance to appropriate interventions for caregivers.
