A study published in PNAS highlights that moderate exercise, such as walking 40 minutes thrice a week, significantly improves memory and cognition in older adults. It showed increased hippocampal volume and enhanced brain health markers, like BDNF, in participants who exercised. Researchers emphasize this as substantial evidence that even modest exercise benefits memory and brain health in sedentary older adults.
