Brain scans may reveal Alzheimer's before symptoms start
NCT ID NCT04579120
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study uses brain scans (PET and MRI) to find early signs of Alzheimer's disease in 650 adults with normal cognition or early-stage symptoms. Participants receive special tracers that highlight amyloid and tau proteins in the brain. The goal is to understand how these biomarkers change over time and predict the onset of Alzheimer's symptoms.

- What this could lead to
- If successful, this study could help identify early markers of Alzheimer's disease, potentially leading to earlier diagnosis and better treatment timing.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly lead to new therapies, and results may not apply to all populations.
