A Trait‐like Component of Subjective Memory Concern in Men from Average Age 38 to 67 Years

Subjective memory concern is a risk factor for dementia in older adults, yet it also appears to be stable over time. Few studies examine memory concern starting in midlife in cognitively normal adults or the role of genetic influences on memory concern. We focused on the stability of subjective memory concern from early midlife into older adulthood and its association with objectively assessed episodic memory and depressive symptoms. Using a classical twin design, we assessed genetic and environmental influences on longitudinally‐assessed subjective concern and its overlap with episodic memory and depressive symptoms.
