1 week agoBlood test holds promise for predicting when Alzheimer's symptoms will start
A simple blood test might one day serve as a molecular 'clock' that predicts not only whether someone will develop Alzheimer's disease - but when. The test, published in Nature Medicine on 19 February, is based on an abnormal form of a protein called tau that circulates in the blood, and begins to accumulate in the brains of people with Alzheimer's well before symptoms such as memory loss appear.
