Sniff training for smell loss after a viral illness
Part of Brain & nervous system clinical trials.
This study tests a smell training program for people who lost their sense of smell after a viral infection like a cold or flu. If you've had smell loss for more than 3 months but less than 2 years, this training might help you regain your sense of smell.

This study uses brain imaging and electrical recordings to understand the brain's role in smell loss from any cause—like COVID, sinus problems, or chemotherapy. You may be eligible if you have any degree of smell loss lasting under a year.
This study tests whether a special device can help older adults regain their sense of smell through regular training with different scents. It is designed for people who have lost smell due to aging or other causes, not from birth.
This trial studies whether structured smell (olfactory) training can improve ongoing smell problems after COVID-19. It may help people whose sense of smell hasn’t fully returned long after the infection.
This study tests whether structured smell “training” can improve smell problems. It’s mainly for people who have had reduced smell for more than 6 months but less than 5 years.
This trial tests if osteopathic manipulative treatment (OMT) can help people regain their sense of smell after COVID-19. OMT is a hands-on therapy used by osteopathic doctors to improve body function.
This study tests a new way of doing smell training to help people whose sense of smell has not recovered after a viral illness. It may help you smell things better again.
