Mass General Brigham researchers used long-term data and a blood test for the biomarker pTau217 to detect the earliest signals of Alzheimer’s disease in cognitively healthy adults. “We used to think that PET scan detection was the earliest sign of Alzheimer’s disease progression, revealing amyloid accumulation in the brain 10 to 20 years before symptoms appear,” said lead author Hyun-Sik Yang, MD, a neurologist with Mass General Brigham Neuroscience Institute and an associate member of the Broad Institute of MIT and Harvard. “But now we are seeing that pTau217 can be detected years earlier, well before clear abnormalities appear on amyloid PET scans.” Learn more about the findings here: http://spklr.io/6047EKqdH
