[2][3], Other olfactory disorders such as hyposmia and anosmia have been found to be a symptom of mood disorders (depression). Due to some phantosmias believed to be caused by a blockage causing the odor molecules to not reach the olfactory receptors, doctors surgically widened the olfactory cleft. It is rare for someone to experience phantosmias without some other existing quantitative condition, such as anosmia. In their findings, it was observed that a typical hallucination period was of 5–60 minutes, occurred either before or with the onset of head pain, and typically consisted of an unpleasant odor. In their 30 months long study, the prevalence rates for phantosmia turned out to be as low as 0.66%. This cancer can become aggressive and progress into the ethmoid sinuses, brain cavity, surrounds the cribriform plate. Both also, however, have instances of phantosmia too, although not as frequently. [3], Another treatment option is the topical solution of cocaine HCl which also provides relief for a short time period by acting as an anesthetic and desensitizing the nasal neurons.
