Overview
Cranial nerve disease is a term used to describe an impaired functioning of one of the twelve cranial nerves.
Although it could theoretically be considered a mononeuropathy, it is not considered as such under MeSH.
It is possible for a disorder of more than cranial nerve to occur at the same time, if a trauma occurs at a location where many cranial nerves run together, such as the jugular fossa. A brainstem lesion could also cause impaired functioning of multiple cranial nerves, but this condition would likely also be accompanied by distal motor impairment.
A neurological examination can test the functioning of individual cranial nerves, and detect specific impairments.
