certain smells, specifically coffees, cigarettes, onions, and perfumes, induced a "nauseating" odor for the patient, which was artificial and  unrelated to a known smell. In another case study cited in the same paper, a woman had parosmia in one nostril but not the other. Medical examination including MRI did not reveal any abnormalities; however the parosmia in this case was degenerative, getting worse in time. The authors report that cases of parosmia can predict regeneration of olfactory senses. Treatment
Symptoms of most patients afflicted with parosmia decrease over time. Although there are instances of parosmia affecting patients for years, this is certainly not the majority of cases. There have been experimental treatments of parosmia with L-Dopa, but there are no other current treatments except inducing anosmia or hyposmia to the point that the odors are negligible. See also
