Finding Alzheimer’s Before a Mind Fails

“Alzheimer’s disease may be a chronic condition in which changes begin in midlife or even earlier,” said Dr. John C. Morris, director of the Alzheimer’s Disease Research Center at Washington University in St. Louis, where Ms. Kerley volunteers for studies. --- Researchers are also using M.R.I. scans to look for early brain changes, and testing blood and spinal fluid for amyloid and other “biomarkers” to see if they can be used to predict Alzheimer’s or find it early.
