A review of studies on coffee and Alzheimer’s disease:
A review of studies consistently supported coffee’s favorable effects against cognitive decline, dementia, and Alzheimer’s disease (AD). In a review done by Eskelinen et al., it was determined that moderate caffeine intake, coffee in particular, is associated with a decreased risk in the diagnosis of dementia/AD. This review included nine longitudinal studies and the CAIDE study (Cardiovascular risk factors, Aging and Dementia). The results from the longitudinal studies were inconsistent, but most studies (3 out of 5) support coffee’s favorable effects against cognitive decline. The CAIDE study showed that drinking 3 to 5 cups per day at midlife appears to decrease the risk of dementia/AD by about 65 percent later on. These findings suggest that coffee drinking may be associated with a decreased risk of dementia/AD. (12)
