In a study following some 1,200 elderly individuals over two decades, investigators discovered that "participants who had moderate to heavy levels of physical activity had about a 40% lower risk of developing any type of dementia." A second study "including data on more than 4,800 men and women ages 65 and older" found that "those who drank tea one to four times a week had average annual rates of decline 37% lower than people who didn't drink tea."

        HealthDay (7/11, Preidt) reported that a third study that "analyzed data from 3,325 people aged 65 and older" found that "the risk of cognitive impairment was 42 percent higher
