New Blood Test That Screens For Alzheimer's May Be a Step Closer To Reality, Study Suggests

Testing a person's blood for a type of protein called phosphorylated tau, or p-tau, could be used to screen for Alzheimer's disease with "high accuracy," even before symptoms begin to show, a new study suggests. CNN: The study involved testing blood for a key biomarker of Alzheimer's called p-tau217, which increases at the same time as other damaging proteins -- beta amyloid and tau -- build up in the brains of people with the disease. The study findings came as no surprise to Ashton, who added that the scientific community has known for several years that using blood tests to measure tau or other biomarkers has the potential to assess Alzheimer's disease risk.
