🧠 Blood p-Tau217: 🩸 A Blood Test That Sees Dementia Coming
About this episode
The episode discusses a blood test that can predict cognitive impairment and its implications for Alzheimer's disease prevention.
🧠 Can a simple blood test predict who will develop cognitive impairment years before symptoms appear? A landmark multicohort JAMA study shows that elevated plasma p-Tau217 strongly predicts progression to cognitive impairment and faster cognitive decline in cognitively normal older adults. The greatest value today is in improving risk stratification and enriching prevention trials—not routine screening of asymptomatic individuals. A major step toward precision prevention of Alzheimer's disease. 🔬🩸 #Alzheimers #Neurology #Biomarkers #PrecisionMedicine #BrainHealth #MedicalEducation #MedicalPodcasts
