Abstract

Objectives: To assess the prevalence of neuropsychiatric symptoms (NPS) in mild-to-moderate Alzheimer disease (AD) and their association with caregiver burden. Methods: Secondary analyses of baseline data from the Trial of Vitamin E and Memantine in Alzheimer's Disease (TEAM-AD) (N=613). Neuropsychiatric Inventory were used to measure severity of NPS and caregiver activity survey to measure caregiver burden. Results: A total of 87% of patients displayed at least 1 NPS; 70% displayed clinically meaningful NPS. The most common symptoms were apathy (47%), irritability (44%), agitation (42%), and depression (40%). Those with moderate AD had more severe NPS than those with mild AD (P =.03). Neuropsychiatric symptoms were significantly associated with caregiver time after adjusting for age, education, cognitive function, and comorbidity (P-value <.0001) with every point increase in NPS associated with a 10-minute increase in caregiver time. Conclusion: Neuropsychiatric symptoms were prevalent in both mild and moderate AD, even in patients receiving treatment with an acetylcholinesterase inhibitors, and were more severe in moderate AD and associated with greater caregiver time.
