You have forgotten where you put your car keys, or you can’t seem to remember the name of your colleague you saw in the grocery store the other day. You fear the worst, that maybe these are signs of Alzheimer’s disease.

You’re not alone: a recent study asking Americans age 60 or older the condition they were most afraid of getting indicated the number one fear was Alzheimer’s or dementia (35 percent), followed by cancer (23 percent), and stroke (15 percent).

And when we hear of someone like legendary basketball Coach Pat Summitt dying on June 28 from early-onset Alzheimer’s at age 64, fears are heightened.

Losing your keys every once in a while does not mean you have Alzheimer’s Disease.
