Could a new PET tracer reveal hidden brain changes in dementia?

NCT ID NCT05384353

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

Summary

This completed study tested a new radioactive tracer called [18F]-SynVesT-1 to measure brain synapse density in 134 people with Alzheimer's disease, frontotemporal degeneration, dementia with Lewy bodies, or late-life psychiatric disorders. Researchers compared this new scan to the standard FDG-PET scan to see which better distinguishes between these conditions. The goal was to understand how synapse loss relates to symptoms, not to provide 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
[18F]-SynVesT-1 (a radioactive tracer for PET scans)
What this could lead to
If successful, this could lead to a better way to diagnose and understand different cognitive disorders by measuring brain synapse health.
What could go wrong
This is a completed observational study, not a treatment trial. The new tracer may not prove more useful than existing methods, and results may not change clinical practice.
