According to a study by researchers with the Mayo Clinic, seniors who play games are less likely to experience mild cognitive impairment (MCI), an intermediate stage of dementia. Nearly 2,000 subjects, 70 years or older were followed for 4 years, interviewed about mentally stimulating activities, and evaluated for cognitive function. Those who played games at least once-a-week were 22 percent less likely to suffer from MCI.
Similar results were also found for craft activities (28 percent), computer use (30 percent), and social activities (23 percent).
The study, published in the January issue of JAMA Neurology, did not control for the same activities performed earlier in life and could not conclusively determine cause and effect.
