6 Common Myths About Aging

Think you know the facts about growing older? Think again.

1. Myth: Dementia is an inevitable part of aging.

Fact: "Dementia should be seen as a modifiable health condition and, if it occurs, should be followed as a medical condition, not a normal part of aging," said Patricia Harris, MD, a geriatrician and associate professor at Georgetown University Medical Center. In other words, if you or your loved one becomes forgetful, it could be related to medication, nutrition or modifiable medical issues, she said. Don't assume Alzheimer's.

Just consider that when doctors examined the brain of a 115-year-old woman who, when she died, was the world's oldest woman, they found essentially normal brain tissue, with no evidence of Alzheimer's or other dementia-causing conditions. Testing in the years before she died showed no loss in brain function.

Not only is dementia not inevitable with age, but you actually have some control over whether or not you develop it.
