New brain scan tracks Dementia-Linked tau buildup in rare language disorders

NCT ID NCT02736695

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

Summary

This study tested a special PET scan tracer (F-18 AV 1451) to see how much tau protein builds up in the brains of 81 people with primary progressive aphasia or frontotemporal dementia. Researchers compared these scans to those of healthy controls to find unique patterns for each disease subtype. The goal was to improve understanding and diagnosis, not to test a treatment.

What this could mean

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

Active substance

F-18 AV 1451 (a radioactive tracer for PET scans)

What this could lead to

If successful, this could help doctors better diagnose and distinguish different types of frontotemporal dementia and primary progressive aphasia using brain scans.

What could go wrong

This is an early-phase, observational study focused on imaging, not a treatment trial. The tracer may not reliably distinguish all subtypes, and results may not directly improve patient care.
