NCT ID NCT07149428
First seen Jun 26, 2026 · Last updated Aug 14, 2026 · Updated 35 times
Summary
This study tracks 80 adults with different smell disorders (like total loss, partial loss, or distorted smell) plus healthy volunteers over one year. Researchers use brain scans, smell tests, and questionnaires to see how the brain changes and how smell loss impacts mood and daily life. The goal is to better understand these conditions, not to test a new treatment.
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 study could reveal how different smell disorders change brain activity and structure, pointing toward better ways to diagnose or treat these conditions.
- What could go wrong
- This is a small, early pilot study (80 people) that only observes and measures—it does not test any treatment. Results may not apply to everyone with smell loss.
