Cognitive leisure activity and incident dementia among older adults with diabetes: a 5-year prospective cohort study
Authors' conclusion
Among older adults with diabetes, higher cognitive leisure activity was associated with lower 5-year dementia risk after accounting for baseline cognitive function, cardiometabolic factors, and measured physical activity, including walking in sensitivity analyses. Cognitive leisure activity may complement other lifestyle factors supporting cognitive health in this population.
