Postmenopausal women who took care of their grandchildren one day a week had better memory and faster cognitive speed (important for warding off dementia) than those who didn’t.
Possible explanation: Active grandparenting includes positive interactions, ongoing learning and mental stimulation—all of which reduce risk for dementia. Careful, though…women who cared for grandchildren five or more days a week had significantly lower cognitive scores, possibly because they felt exhausted.
