40.What new announcement has been made about the early detection of Alzheimer's

• they wish to do research in an intensive manner on moving Alzheimer's diagnosis to a completely biological definition based on biomarkers. • The three biomarkers they are going to focus on are: Tau, Amyloid, and Neurological damage that can be visualized and quantified by scans • Hope to give people definitive diagnosis of Alzheimer's based on a series of tests that could be done in a day. Another hope is to get an early diagnosis when the process of Alzheimer's is just beginning and not really starting to affect the memory. If diagnosis is early perhaps damage could be prevented.
