Moderate exercise may be one key to cutting the risk of silent strokes as we age, according to researchers.

Silent strokes usually have no symptoms, but they can lead to problems such as memory loss.

Researchers in New York and Miami tracked 1,200 older people who had no prior history of strokes.

After six years, they found that those who regularly engaged in moderate to intense exercise, such as brisk walking or playing tennis, were 40 percent less likely to have brain lesions indicating a silent stroke.
