WASHINGTON (AP) -- About 800 older Americans will be asked to lend their brains to science this spring, part of a major government study to track early Alzheimer's disease.
Researchers will use brain-scanning MRIs and other tests to track people who have either early stage Alzheimer's or a milder type of memory loss known as "mild cognitive impairment." Over several years, they'll compare biological changes deep within those patients' brains to the aging that takes place in the brains of cognitively healthy seniors.
