hemiparesis

Last reviewed 01/2018

Hemiparesis is weakness of the whole of one side of the body.

It may be due to an upper motor neurone lesion deep in the contralateral hemisphere, i.e. involving the internal capsule.

It is very unlikely that a hemiparesis could be caused by lower motor neurone lesions - it is impossible for it to be caused by a single lower motor neurone lesion.
