Good News: Exercise Can Prevent Dementia!

All boomers and even those who are not yet boomers worry at times about the potential for cognitive decline or dementia. The good news is that neither is inevitable. The magic bullet to avoid those dreaded aspects of aging:  good old-fashioned aerobic exercise.

A number of recent studies have shown that while brain volume shrinks as we age, exercise can reduce the amount of shrinkage and actually produce new neurons in the brain. In one of those studies at the Cooper Institute in Dallas, Texas, the researchers followed over 19,000 adults for some  24 years to determine if exercise could prevent dementia and even Alzheimer's.  The good news is that those persons who were the most fit had the least amount of dementia.

The studies show that the most beneficial form of exercise is aerobic, such as walking, running, cycling and swimming. Most importantly, the studies have shown that it is never too late to start exercising.  Whichever form of exercise you choose, it is important that you keep at it consistently. Optimally about 2 and one half hours of aerobic activity per week is enough to keep those neurons growing..
