Additive Effects of Cognitive Function and Depressive Symptoms on Mortality in Elderly Community-Living Adults

摘要

BackgroundPoor cognitive function and depressive symptoms are common in the elderly, frequently coexist, and are interrelated. Both risk factors are independently associated with mortality. Few studies have comprehensively described how the combination of poor cognitive function and depressive symptoms affect the risk for mortality. Our aim was to examine whether the combination of varying levels of cognitive function and depressive symptoms affect the risk of mortality in community-living elderly adults.
