Amyloid Deposits in Cognitively Normal People May Predict Risk for Alzheimer’s Disease

For people free of dementia, abnormal deposits of a protein associated with Alzheimer’s disease are associated with increased risk of developing the symptoms of the progressive brain disorder, according to two studies from researchers at Washington University in St. Louis. The studies, primarily funded by the National Institute on Aging (NIA), part of the National Institutes of Health, linked higher amounts of the protein deposits in dementia-free people with greater risk for developing the disease, and with loss of brain volume and subtle declines in cognitive abilities.
