The Alzheimer's Association is launching a campaign reminding Americans of that. It's called "Maintain Your Brain."
The head of the association's Medical Science Advisory Committee, Doctor Marilyn Albert, says some of the same steps you'd take to help your heart will be beneficial to your brain as well, such as lowering your blood pressure and cholesterol.
The association is releasing a new survey that it says shows that a lot of Americans aren't aware of advances being made against Alzheimer's. It says fewer than half are aware that new treatments can ease Alzheimer's symptoms and improve quality of life.
Alzheimer's disease affects 4.5 million Americans. By 2030, when the baby boomer generation is older than 65, nearly eight million people are expected to have Alzheimer's.
