<unk>  is an impaired functioning of one of the twelve<unk><unk> s. 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 one<unk><unk>  to occur at the same time, if a trauma occurs at a location where many<unk><unk> s run together, such as the jugular fossa. A brainstem lesion could also cause impaired functioning of multiple<unk><unk> s, but this condition would likely also be accompanied by distal motor impairment. A neurological examination can test the functioning of individual<unk><unk> s, and detect specific impairments.
