NCT ID NCT06115291
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether daily exposure to different scents can retrain the sense of smell in 250 adults with smell disorders, including those from traumatic brain injury. Participants will use scented inhaler sticks at home and take smell tests before and after 12 weeks. The goal is to see if this simple, drug-free method can improve smell detection and identification.

aromatherapy inhaling sticks with various scents
What this could lead to
If it works, this could provide a simple, drug-free way to help people regain their sense of smell after injury or illness.
What could go wrong
