Chunk #45 — FINDINGS — Relation of Risk Factors to Cognitive and Motor Outcomes, Disability and Death — Cognitive, Physical Activities, Social Engagement, Loneliness and Life Space
Social engagement, specifically social activity and social support, though not social networks, was associated with global cognition and diverse measures of specific cognitive domains, especially perceptual speed [69]. Late life social activities were also related to a slower rate of decline in cognitive and motor function even after controlling for physical and cognitive activities [118–120]. Social engagement was also related to incident disability [121]. The related construct of loneliness was also associated with risk of AD and rate of cognitive decline, even after controlling for the effect of social activity [119]. It was also associated with the rate of decline in motor function [122].
