Can brain scans and eye tests predict Alzheimer's years before symptoms?

NCT ID NCT05806697

First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time

Summary

This study follows older adults (ages 70-95) who have memory concerns but no dementia, tracking them for up to 5 years to see who develops Alzheimer's. Researchers use brain scans, EEG, eye movement tests, and memory assessments to spot early warning signs. The goal is to better understand how Alzheimer's unfolds in its earliest, pre-symptomatic stage.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could help identify early markers of Alzheimer's disease before symptoms worsen, enabling earlier intervention.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly improve health. It may not find reliable predictors, and results may not apply to broader populations.
