"Blood Protein Test Predicts Dementia 15 Years in Advance"

A study analyzing blood proteins has identified biomarkers that can predict the risk of developing dementia up to 15 years before diagnosis, potentially leading to the development of blood tests for early detection of diseases such as Alzheimer's. High levels of four proteins - GFAP, NEFL, GDF15, and LTBP2 - were found to be strongly associated with dementia, and a predictive model combining these biomarkers with demographic factors showed about 90% accuracy in predicting the incidence of dementia subtypes more than ten years before diagnosis. While the findings are promising, further validation is needed before these biomarkers can be used as clinical screening tools.
