How is parosmia treated?

Parosmia is typically treated with something known as olfactory training or scent training, which involves inhaling a particular scent and thinking about what that scent should smell like. So, if you were inhaling the scent of lemon, you would try to remember what lemon smells like at the same time.

People who did scent training for six months showed “clinically relevant improvements” in their ability to accurately smell scents by the end of the trial.
