In general, anosmia has no effective treatment. Instead, healthcare professionals aim to treat specific underlying causes in the hope that the anosmia will resolve. However, the ability to smell may not return even with successful treatment of the initial cause. Steroids have proven beneficial at improving anosmia that results from nasal inflammation. Gene therapy is very early in development but shows potential for restoring a sense of smell in rats born with congenital anosmia. It is possible that gene therapy will be an effective treatment for humans with anosmia in the future, but more research is needed.
