According to the Alzheimer’s Association, one in six women over the age of 65 are at risk for developing Alzheimer’s. That’s compared to a one in eleven chance of developing the disease for men of the same age. Put another way, two-thirds of all Americans with Alzheimer’s are women. But why?
The simple answer — though the science behind it is far from simple — may be that women’s brains age differently than men’s do.
