ASMR Cranial Nerve Exam Examination
Cranial nerve I deals with olfactory function which is olfaction. Whenever a doctor does a cranial nerve exam, it is very important observe all functions of each cranial nerve. For CN I the physician should take notice of the away from the nose. A doctor should take notice of the interior of your nose. A doctor must then test either side for olfactory function.

Next is completed somewhere, the procedure is then repeated on the other half nostril. This is testing for full olfactory function.

Anosmia is a complete loss of smell. Unilateral indicates that the person is less likely to be hallucinating. This is often due to a viral infection, allergies, aging, head trauma creating a basilar skull fracture. Rhinorhea or cerebral spinal fluid drainage and backwash meningitis may also be possible. Head and neck injuries resulting in the cribiform plate to shear off neurons which are descending from the olfactory bulb also can cause anosmia. A feeling of smell may return eventually secondary to injury, however it usually won't. In the event the anosmia is bilateral choose a blocked nasal passage, common cold, trauma, and relative loss can happen with age. Hyposmia indicates a possible lesion in the uncinate gyrus from the anterior temporal lobe causing hallucinations of smell connected with strong feelings of d�j� vu, called uncinate fits or seizures. Hyperosmia can be the perversion of smell, and cacosmia, the abnormally disagreeable smell which may also indicate a lesion on the uncinate gyrus
