A healthy lifestyle may offset genetic risk for Alzheimer's

A healthy lifestyle can cut your risk of developing Alzheimer's or other forms of dementia even if you have genes that raise your risk for these mind-destroying diseases, a large study has found. People with high genetic risk and poor health habits were about three times more likely to develop dementia versus those with low genetic risk and good habits, researchers reported Sunday. Regardless of how much genetic risk someone had, a good diet, adequate exercise, limiting alcohol and not smoking made dementia less likely.
