(UPI) – In a discovery that challenges conventional thinking, researchers report that several people over the age of 90 had excellent memory even though their brains showed signs that they had Alzheimer’s disease. The meaning of the findings isn’t entirely clear. The elderly people, whose brains were studied after their deaths, may have been in the early stages of Alzheimer’s, although the researchers said they doubt this. It’s also possible that something about these people — or their brains — could have kept dementia symptoms in check.
