About five million Americans suffer from Alzheimer's Disease or some other form of dementia. And that number is expected to rise rapidly as baby boomers age.
Alzheimer's affects one in nine people over the age of 65 and about a third of those 85 and older, according to the Alzheimer's Association.
It's a terrible disease. I know first-hand because my mother, aunt and grandmother had it.
There are new medications, but they can only temporarily ease some symptoms.
Scientists still don't even know exactly how the disease forms. They believe Alzheimer's begins ravaging the brain at least a decade before memory problems appear, much like heart disease is triggered by quiet cholesterol build-up.
That's why there's a growing believe that the best chance of preventing or at least slowing the disease requires intervening, somehow, when people still appear healthy.
June is Alzheimer's & Brain Awareness Month. This might be a good time to check out the Alzheimer Association's website. It's filled with the latest information about the disease, plus advice and support for families caring for a loved one with dementia.
ABC News also has an Alzheimer's Answer Center.
