Behavioral Pathology in Alzheimer’s Disease (BEHAVE-AD) Rating Scale

Abstract

Before the development of the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD) rating scale in 1987 by Reisberg and colleagues and its predecessor scale, the Symptoms of Psychosis in Alzheimer's Disease (SPAD) rating scale, in 1985 by Reisberg and Ferris, other scales were available for measuring behavioral disturbances and psychiatric disorders in patients with Alzheimer's disease. However, these scales generally mixed together cognitive disturbances with behavioral symptoms and sometimes included functional impairments as well. These predecessor scales also were not specifically designed to assess the types of behavioral problems seen in Alzheimer's disease. If a scale did address behavioral disturbances of dementia, it tended to be seriously underspecified in terms of the nature of behavioral disturbances.
