Brain scan could spot early dementia clues

NCT ID NCT03372317

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study uses a special PET scan to detect tau protein buildup in the brains of healthy older adults and those with mild cognitive impairment. Researchers will compare scan results with memory tests and brain activity patterns to understand how tau affects thinking. The goal is to learn more about early signs of dementia, not to test a treatment.

What this could lead to
If successful, this could help identify early signs of dementia and improve understanding of how tau buildup affects memory and thinking.
What could go wrong
This is an observational imaging study, not a treatment trial. It may not lead directly to new therapies, and results may not apply to all populations.
