Transient post-traumatic hemiballism. Report of a case.
Hemiballism is a rare movement disorder which is due to lesion or malfunction of the subthalamic nucleus (STN) and its connections, according to various neurophysiological data. Various causes of this condition have been described, usually related to basal ganglia dysfunction. There are only three references in the literature of traumatic hemiballism. We report a case of post-traumatic hemiballism, due to a contusion of the subthalamic regional area, and review the relevant literature.
