![]() ![]() Īnother case of a 70-year-old male reported that his first abnormal symptoms were irregular bowel movements. Other studies have also found that the symptoms of phantosmia have been alleviated after the patient has been treated for depression. ![]() It may also be a sign of an intracranial hemorrhage (brain tumours or epilepsy). It has been proposed that phantosmia may be an early sign of the neurodegenerative disease Parkinson's disease. However, it is not known what olfactory disorders occur and if they are indeed a symptom of a depressive disorder. Other olfactory disorders such as hyposmia and anosmia have been found to be a symptom of mood disorders (depression). If the problem persists or causes significant discomfort, a doctor might recommend nasal saline drops, antidepressant or anticonvulsant medications, anesthesia to parts of the nose, or in very rare circumstances, surgical procedures to remove the olfactory nerves or bulbs. When caused by an illness (e.g., sinusitis), it should go away when the illness resolves. Phantosmia usually goes away on its own, though this can sometimes be gradual and occur over several years. Ī physician can determine if the problem is with the sense of smell ( olfactory system) or taste ( gustatory system), or if it is caused by a neurological or psychiatric disorder. Environmental exposures are sometimes the cause as well, such as smoking, exposure to certain types of chemicals (e.g., insecticides or solvents), or radiation treatment for head or neck cancer. It can also be a symptom of certain mental disorders such as depression, bipolar disorder, intoxication or withdrawal from drugs and alcohol, or psychotic disorders. It can result from neurological conditions such as migraines, head injuries, strokes, Parkinson's disease, seizures, or brain tumors. Olfactory hallucinations can be caused by common medical conditions such as nasal infections, nasal polyps, or dental problems. When hallucinations of this type do not seem to go away or when they keep coming back, it can be very upsetting and can disrupt an individual's quality of life. Experiencing occasional phantom smells is normal and usually goes away on its own in time. Unpleasant phantosmia, cacosmia, is more common and is often described as smelling something that is burned, foul, spoiled, or rotten. This is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology. Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, is smelling an odor that is not actually there. ![]()
