Weight Change in Alzheimer's Disease

Abstract

Clinically important weight loss occurs more frequently among patients with AD than among cognitively normal control subjects. Instances of weight gain, periods of acute weight loss, and greater fluctuations in weight suggest that the natural history of weight change in AD may be characterized by dysfunction in body weight regulation. Further analysis is warranted regarding the relationship of severity of dementia, functional status, and other specific aspects of AD to weight change.
