Abstract
OBJECTIVE: To determine if behavioral symptoms detected at initial evaluation relate to cognitive or functional status or survival time in Alzheimer's disease (AD) patients. method: Review, in 100 cases of autopsy-proven AD, of the relationship of behavioral symptoms detected at initial evaluation to cognitive and global function measures and survival time. RESULTS: Behavioral symptoms had occurred in 74% of patients, including apathy (51%), hallucinations (25%), delusions (20%) and depressed mood (6.6%). Verbal aggression was common (36.8%); physical aggression less so (17%). The symptomatic group was more functionally (but not cognitively) impaired and had shorter median survival time (8 years: 95% CI: 7-9 years vs. 10 years: 95% CI: 8-12 years; P = 0.002) than the asymptomatic group. The presence of any one symptom at initial evaluation accounted for 6.1% of the variance in duration of illness. CONCLUSION: Presence of behavioral symptoms at initial evaluation of AD patients is associated with greater functional impairment and shorter survival time. Copyright Blackwell Munksgaard 2005.
