NCT ID NCT07142954

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This 7-year study follows 3,400 adults who report no memory problems but may be at risk for Alzheimer's. Researchers will use a blood test measuring P-tau217, a protein linked to Alzheimer's, to see if higher levels predict faster cognitive decline. The goal is to better understand how the disease progresses before symptoms appear.
