Copper has cropped up as a possible culprit in Alzheimer’s disease, but two new studies turn that penny on its head.Researchers say mice with more copper in their brain cells are less likely to develop the toxic protein fragments called amyloid-beta associated with Alzheimer’s. In one study, German scientists found mice with a genetic predisposition to the brain disease lived longer and had less amyloid-beta when they drank copper-laced water than did those that didn’t get the supplements.
