Electrical nerve stimulation combined with smell training for smell loss

This study is testing a new approach to help people who have lost their sense of smell. The treatment combines trigeminal nerve stimulation—a gentle, pain-free electrical stimulation applied to the forehead—with smell training exercises. Researchers believe this combination may work better and faster than smell training alone.

Smell loss is a real health problem that can make it hard to detect dangers like gas leaks or spoiled food, and it often affects people's quality of life and mood. Current smell training requires months of daily practice, and many people stop doing it before seeing good results. This trial is testing whether adding electrical stimulation could make the treatment work better and require less time.
