NCT ID NCT07681973

First seen Jul 02, 2026 · Last updated Jul 02, 2026

Summary

This study looks at people with smell loss caused by chronic rhinosinusitis. Participants will undergo a 3-month smell training program. Researchers will measure changes in smell function, mental health, and immune markers in blood and tissue samples. The goal is to understand the links between smell loss, cognition, and the immune system to help develop future treatments.
