Blood test method may predict Alzheimer's protein deposits in brain

(NIH/National Institute on Aging) Researchers report an advance in the development of a blood test that could help detect pathological Alzheimer's disease in people who are showing signs of dementia. This approach could be less invasive and less costly than current brain imaging and spinal fluid tests. The study, funded by the National Institutes of Health, was published on March 2 in Nature Medicine.
