Sunshine, tea and exercise may ward off dementia


Three long-term studies suggest diet and exercise may help reduce the risk of developing dementia in older adults.

The studies were presented at the Alzheimer’s Association International Conference in Honolulu, Hawaii recently.

In a study from Brigham and Women’s Hospital in Boston of 1,200 elderly people, researchers said that participants who performed moderate to heavy levels of physical activity had about a 40-percent lower risk of developing any type of dementia.

The study also suggested that participants who reported the lowest levels of physical exercise were 45 percent more likely to develop dementia.

A University of California, Los Angeles study of more than 4,800 men and women aged 65 and older suggested that tea drinkers were between 17 and 37 percent less likely to develop dementia. The researchers saw similar effects in coffee drinkers, but only in those who drank large quantities.

A University of Exeter Peninsula Medical School study of 3,325 people 65 and over suggested vitamin D deficiency could cause dementia. The researchers said that the odds of cognitive impairment were more than 40 percent higher in people who were vitamin D deficient.

Those who the researchers called “extremely deficient” were at a more than 390 percent risk of developing dementia.
