anosmia causes
Causes of the Disorder. The primary causes of anosmia include obstruction (blockage) of the nasal passageways, destruction of the tissue lining the nose through inflammation or swelling, and a loss of nerve transmission from sensory neurons in the nose to the brain.
Anosmia caused by a treatable condition, such as nasal polyps or sinusitis, can be reversed. The treatment goal is to remove the obstruction or the cause of nasal swelling. If anosmia is caused by a drug, the medication can be discontinued. Once corrective measures are taken, the sense of smell may be restored.
Anosmia (/Ã¦nËÉzmiÉ/) is the inability to perceive odor or a lack of functioning olfactionâthe loss of the sense of smell. Anosmia may be temporary, but some anosmia (including traumatic anosmia) can be permanent. Anosmia is due to a number of factors, including an inflammation of the nasal mucosa, blockage of nasal passages or a destruction of one temporal lobe. Inflammation is due to chronic mucosa changes in the paranasal sinus lining and the middle and superior turbinates.
Anosmia or Loss of Smell Caused Due to Damage to Innermost Lining of the Nose: Sometimes due to conditions like acute sinus infections there is irritation of the mucous membranes on the inside of the nose. This may cause temporary or permanent loss of ability to smell or Anosmia.
