Certain lifestyle factors can sway the risk of dementia, and a new study points to the top threats to Americans these days: obesity, physical inactivity and lack of a high school diploma.
Researchers found that in just the past decade, there has been a shift in the most important modifiable risk factors for dementia in the United States. In 2011, the big three were physical inactivity, depression and smoking.
Today, lack of exercise is still among the top three, but the other spots have been replaced by obesity in middle-age and low education levels (not graduating from high school).
