Could a blood test predict if you’ll get Alzheimer’s years before symptoms appear?

DNA, RNA blood test may help detect Alzheimer’s earlier: study

Seoul National and Indiana University developed a genomic-transcriptomic blood test for Alzheimer's with 56–80% accuracy in high-risk screening. This noninvasive, cost-effective screening enables population risk stratification without expensive imaging, reducing diagnostic burden while accelerating early detection for health IT and diagnostic platforms.
