Scientists Create Blood Test that Predicts Dementia 25 Years Before Symptoms Appear

Early detection could give doctors and researchers more time to understand the disease and possibly slow its progress. Researchers from the University of California San Diego carried out this study discovered that higher levels of a protein called phosphorylated tau 217, or p tau217, were linked to a higher chance of developing memory and thinking problems later in life. This finding could help doctors recognize risk much earlier than before.
