| '''''Synonyms and keywords:''''' cranial nerve palsy, cranial nerve disorder
| |
| | |
| ==Overview==
| |
| '''Cranial nerve disease''' is a term used to describe an impaired functioning of one of the twelve [[cranial nerves]]. This results in loss of control of facial muscles, erratic movements of the face muscles, or spastic jerks of the face muscles.
| |
| | |
| 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.
