w findings also suggest that one way in which physical exercise could improve memory is via lowering glucose levels. Dr. Small's previous imaging studies in humans and in mice have documented that among all hippocampal subregions, physical exercise causes an improvement in dentate gyrus function.

"By improving glucose metabolism, physical exercise also reduces blood glucose. It is therefore possible that the cognitive enhancing effects of physical exercise are mediated, at least in part, by the beneficial effect of lower glucose on the dentate gyrus. Whether with physical exercise, diet or through the development of potential pharmacological interventions, our research suggests that improving glucose metabolism could be a clinically viable approach for improving the cognitive slide that occurs in many of us as we age," concluded Dr. Small.

With increasing longevity and the aging of the baby boom population, cognitive decline has emerged as a major health care crisis and concern.
