- Study shows a blood test can help identify healthy people at high risk for Alzheimer's disease
A blood test measuring p-tau217 levels can predict the risk of Alzheimer's disease in symptom-free older adults, with high levels correlating to a 38% five-year and 78% ten-year risk of cognitive decline. The test is currently used in clinical settings to aid diagnosis but is not yet recommended for healthy individuals, as no interventions exist for early-stage prevention.
- Study shows a blood test can help identify healthy people at high risk for Alzheimer's disease
A blood test measuring p-tau217 can predict the risk of Alzheimer's disease in healthy older adults, with high levels correlating to a 78% risk of cognitive impairment within 10 years. Researchers caution the test is not yet ready for general use but emphasize its potential to aid drug development and clinical trials.
