Blood tau clock could forecast when Alzheimer’s symptoms begin
TL;DR Summary
A Nature Medicine study describes a blood test that detects an abnormal form of tau in the blood, which may serve as a molecular clock to predict not only if someone will develop Alzheimer’s but also when symptoms could start. If validated in larger trials, it could enable earlier interventions and streamline clinical testing for therapies, though experts caution that it’s not yet recommended for cognitively unimpaired individuals to use this biomarker outside of research.
