Blood Test Shows Potential to Predict Alzheimer's Risk in Healthy Older Adults

A study published in JAMA suggests that a blood test measuring phosphorylated tau 217 (P-tau217) could help estimate the risk of developing cognitive impairment in healthy older adults over several years. Higher levels of P-tau217 were linked to an increased risk of progression. Researchers caution that the test is not yet ready for general clinical use outside of research settings.
