The authors assessed a consecutive series of 196 patients with probable Alzheimer's disease (AD) for the presence of aggressive behavior, using a standardized neurological, neuropsychiatric, and neuropsychological battery that included both the Overt Aggression Scale and the Irritability Scale. Twelve percent of patients showed aggressive episodes (5% with verbal aggression, 7% with physical aggression) during the 4 weeks preceding the psychiatric evaluation. Physical aggression was significantly associated with more frequent delusions and more severe irritability.
