title: Selected psychiatric symptoms associated with rate of cognitive decline in patients with Alzheimer's disease.
abstract: We examined the relation between selected psychiatric symptoms and the average rate of decline in different areas of cognition in patients with Alzheimer's disease. Measures of decline were computed by determining patients' average rates of decline on the underlying factors of the Mini-Mental State Examination (MMSE). Patients with agitation or wandering declined more rapidly on the total MMSE score than did patients without either symptom. The Following Commands factor accounted for almost all of this decline. The findings suggest a relation between the presence of certain behavioral problems in Alzheimer's disease and decline in particular cognitive areas.
