Alzheimer's Detection Is Moving Upstream: Care Has Not Caught Up

🧬
Biology-First Diagnosis
  • Alzheimer's begins years before symptoms
  • Blood biomarkers (pTau217) enable early detection
  • Diagnosis now occurs while patients are asymptomatic

"An abnormal biomarker is sufficient to establish a diagnosis."

⚠️
The New Problem
  • No tools for day-to-day cognitive monitoring
  • No visibility into real-world functioning
  • Care systems activate too late
They have Alzheimer's… now what?
