Blood-based test can predict risk of developing symptoms of Alzheimer's up to a decade early
medicalxpress - A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged about the extent to which such tests can accurately predict whether a cognitively healthy individual will develop cognitive im…
AI Summary: Researchers validated a blood‑based test that flags individuals at elevated risk of developing Alzheimer’s symptoms up to a decade earlier, showing strong predictive accuracy across cohorts. The finding could enable earlier monitoring and trial enrollment, but raises questions about screening protocols, follow‑up care and the psychological burden of long‑lead risk information.
