Dementia Prevention: Brain Exercise
In one study over an average period of 5.4 years, dementia developed in 124 of 465 subjects. Researchers found that among leisure activities, reading, playing board games, playing musical instruments, and dancing were associated with a reduced risk of dementia!
The authors of the study concluded that participation in leisure activities is associated with a reduced risk of dementia. They suggested that further studies be done to determine the power of the "protective" effect of leisure activities that involve thinking on the risk of dementia.
