Smell training plus brain stimulation for long COVID smell loss

Charleston, South CarolinaAges 18–65 - NCT07127224Recruiting
Predicting recovery with smell tests in coma

Common questions
- Are there clinical trials for olfactory disorder?
- Yes. Clin2 currently lists 8 recruiting olfactory disorder studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a olfactory disorder trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a olfactory disorder trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
