E. Chemerinski et al., PREVALENCE AND CORRELATES OF AGGRESSIVE-BEHAVIOR IN ALZHEIMERS-DISEASE, The Journal of neuropsychiatry and clinical neurosciences, 10(4), 1998, pp. 421-425
The authors assessed a consecutive series of 196 patients with probabl
e Alzheimer's disease (AD) for the presence of aggressive behavior, us
ing a standardized neurological, neuropsychiatric, and neuropsychologi
cal battery that included both the Overt Aggression Scale and the Irri
tability 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 si
gnificantly associated with more frequent delusions and more severe ir
ritability.
