Physical Activity is Beneficial for Late-life Cognition

In a study conducted at the University of Eastern Finland, it was found that those individuals who engage themselves in any form of physical activity at least twice a week had a lower risk of dementia than individuals who were less active. Individuals continuing physical activity after midlife were also found to lower their risk of dementia as well. Leisure-time physical activity (LTPA) has always been important to one's ones in general, especially, their cardiovascular health. The correlation between LTPA and lowering the risk of dementia was seen to be particularly strong among overweight and obese individuals.

Since the sample size was relatively small, I would like to definitely see some more studies conducted to confirm this correlation being made. More information about dementia can be read from WebMD.
