Blood Tests Offer New Hope for Alzheimer's Diagnosis | JQJO

Researchers have developed a new blood test to detect Alzheimer's disease and its progression. The test measures levels of tau protein fragments (eMTBR-tau243), correlating with tau tangle buildup in the brain. This test shows promise in aiding drug selection and monitoring disease progress, performing better than existing methods, though further development is needed for widespread use. Separate research identified a protein ratio (YWHAG:NPTX2) in brain fluid that also effectively indicates cognitive impairment and predicts future decline. Both studies highlight potential advancements in Alzheimer's diagnosis and treatment.
