WASHINGTON (Reuters) - New tests involving blood and brain scans can detect symptoms of Alzheimer’s disease, and brief appraisals of real-life functioning can predict who is likely to develop it, researchers said on Sunday.The tests will be critical, experts told a meeting on Alzheimer’s disease, because more than 26 million people now have the brain-wasting disease and this number will quadruple, to 106 million, by 2050.
