The times they are a-changin': cohort effects in aging, cognition, and dementia
Abstract
Two papers recently published in IPG point toward decreasing rates of cognitive decline and dementia in high-income countries. (Dodge et al., 2016; Kosteniuk et al., 2016). These reports join the ranks of a growing body of literature on generational trends, or more, specifically, "cohort effects," in aging, cognitive decline, and dementia.
