Yet another reason to lace up those gym shoes and get moving: A new report from the "Institute of Medicine" links exercise with an aging sharp mind. Though changes in the brain are inevitable as we grow older, it’s a relief to know that we may have some control over slowing down the negative effects, such as memory loss and attention decline. Of course, it takes some work on our part. A few suggested activities (apart from getting consistent exercise) include: managing high blood pressure and diabetes, quitting smoking, getting good sleep and participating in new classes or activities. Interestingly enough, learning how the brain changes with age is still a relatively new frontier, says Victor Dzau, president of the Institute of Medicine. But as the population of older Americans increases, there’s promise that more research about cognitive health will grow .
