Cognition and depression in a cohort of aging men: results from the Western Collaborative Group Study.
Relationships between cognitive performance and self-ratings of depression on the Center for Epidemiologic Studies Depression scale (CES-D; L.S. Radloff, 1977) were examined for 1,217 older men. After controlling for demographic variables and both objective and subjective measures of health, significant associations were observed between several CES-D variables and measures of cognitive mental status, memory, and psychomotor speed. The Well-Being factor of the CES-D was the most robust predictor of cognitive scores. Therefore, for older adults with generally favorable health and socioeconomic resources, there may be a link between positive affect and maintenance of cognitive effectiveness.
