This study presents data on 17 elderly patients who were prospectively examined for up to 4 weeks for acute EPS, functional and cognitive status, and behavioral disturbances. Seventy-one percent of subjects developed DIP, and 18% developed akathisia. Predictors of DIP included pre-neuroleptic treatment parkinsonian signs and neuroleptic dose, despite use of low doses of neuroleptics. Development of acute EPS was associated with failure to improve behaviorally. New-onset urinary incontinence was the most common functional abnormality.
