Active social life may prevent dementia

A study in the July issue of the American Journal of Public Health finds if you are socially engaged you are at a lower risk of dementia.

In the study, those with large social networks reduced their risk of getting dementia by 26 percent. Previous studies have shown mixed results, indicating that being married may or may not be helpful.

This study found marriage didn't make a difference in terms of dementia risk. It was the social network that was protective.
