ASMR Cranial Nerve Exam Examination
Anosmia can be a complete lack of smell. Unilateral indicates that the patient is less inclined to be hallucinating. This is as a result of viral infection, allergies, aging, head trauma producing a basilar skull fracture. Rhinorhea or cerebral spinal fluid drainage and backwash meningitis can also be possible. Head and neck injuries resulting in the cribiform plate to shear off neurons which can be descending from the olfactory bulb can also cause anosmia. The experience of smell may return eventually secondary to injury, but it usually won't. When the anosmia is bilateral locate a blocked nasal passage, common cold, trauma, and relative loss may appear with age. Hyposmia indicates a potential lesion from the uncinate gyrus from the anterior temporal lobe causing hallucinations of smell linked to strong feelings of d�j� vu, called uncinate fits or seizures. Hyperosmia can be the perversion of smell, and cacosmia, which is the abnormally disagreeable smell which could also indicate a lesion on the uncinate gyrus
