New Blood Test May Predict Alzheimer's Risk in Healthy Seniors

A recent study published in JAMA suggests a blood test, measuring phosphorylated tau 217 (P-tau217), could help estimate the risk of developing cognitive impairment over several years in healthy older adults. Individuals with high levels of this biomarker showed a significantly increased risk of cognitive decline within 5 to 10 years. While promising for research and drug development, experts caution that the test is not yet ready for general clinical use outside of research settings.
