Patients like this have long been “called the worried well,” said Creighton Phelps, acting chief of the dementias of aging branch of the National Institute on Aging. “People would complain, and we didn’t really think it was very valid to take that into account.”
But now, scientists are finding that some people with such complaints may, in fact, be detecting early harbingers of Alzheimer’s. Studies presented Wednesday at an Alzheimer’s Association conference in Boston show that people with some types of cognitive concerns were more likely to have Alzheimer’s pathology in their brains, and to develop dementia later. Research presented by Dr. Amariglio, for example, found that people with more concerns about memory and organizing ability were more likely to have increased levels of amyloid, a key Alzheimer’s-related protein, in their brains.
