The study included 758 participants “with unimpaired cognition, mild cognitive impairment, or dementia from the Washington Heights-Inwood Columbia Aging Cohort,” the authors wrote.
Each participant had a brain scan and was tested for thinking speed and memory.
“Taking part in more mental activities was associated with greater thinking speed reserve for both men and women,” Pa said.
Only women, however, saw a benefit between cognitive activities and memory reserve, the study found.
“In this study, a twofold increase in physical activity was equivalent to about 2.75 fewer years of processing speed aging in women,” Dr. Richard Isaacson, director of the Alzheimer’s Prevention Clinic in the Center for Brain Health at Florida Atlantic University’s Schmidt College of Medicine, told CNN, who first reported the study. “Further, each extra cognitive activity corresponded to 13 fewer years of processing speed aging on average between women and men.”
“Any woman reading this story can feel empowered to take control of their brain health today by staying physically active and cognitively engaged,” Isaacson told CNN.
