Cut Your Risk of Alzheimer’s Disease

There’s good news and bad about Alzheimer’s. Current medications only minimally delay progression of the disease, says Lon S. Schneider, who directs the Alzheimer’s Disease Research and Clinical Centre of California. But evidence is piling up that you can lower your risk by making some simple changes in your life, researchers say. What matters most :

SKIP THE CHIPS. Eating too much fat and cholesterol seems to hasten the onset of Alzheimer’s, at least in a recent mice study; in human studies, being obese in midlife raises the risk of later memory problems, dementia, and Alzheimer’s. The flip side: A 2006 study of more than 3700 older adults found that those who ate plenty of vegetables slowed the decline of their mental abilities by 40 percent, compared with those who skimped on their greens.

TAKE A WALK IN THE SUN. A study of nearly 2000 people last year suggests that vitamin D –the “sunshine vitamin” –could help keep your brain sharp. Among volunteers 65 years and older, those with the lowest levels of the vitamin were more than twice as likely to have cognitive impairment as those whose levels were optimal.

EXERCISE YOUR BRAIN. Two recent studies found that people who had spent more years in school or had worked in mentally demanding jobs stayed sharper, even when their brains were damaged by the plaques and tangles of Alzheimer’s disease. Lifelong hobbies such as playing cards or doing crossword puzzles might also help protect against the symptoms of Alzheimer’s disease.

MAKE TIME FOR FRIENDS. A little chatting can have a big payoff. A Harvard study last year found that socially connected people kept more of their memory intact as they aged –up to twice as much, according to one measure.

KEEP MOVING. In a study of middle-aged and elderly adults with mild memory problems, those who started walking several times each week scored significantly higher on memory tests after just six months.
