Anosmia

Clinic

• Also known as smell blindness, is the loss of the ability to detect one or more smells.
• Anosmia may be temporary or permanent. It differs from hyposmia, which is a decreased sensitivity to some or all smells.

Causes

• Inflammation of the nasal mucosa, blockage of nasal passages or
• Destruction of one temporal lobe.

When anosmia is caused by inflammatory changes in the nasal passageways, it is treated simply by reducing inflammation.

• It can be caused by chronic meningitis and neurosyphilis that would increase intracranial pressure over a long period of time.
• Ciliopathy, including ciliopathy due to primary ciliary dyskinesia.
