Subthalamic lesion and paroxysmal tonic spasms


  • A videotape accompanies this article.


Paroxysmal dyskinesia due to a subthalamic lesion is a rare finding. We describe a patient with paroxysmal tonic spasms due to a well-defined lesion in the subthalamic area. In this case, we confirm the nonepileptic nature of the episode and collect with detail the clinical features by means of a video-electroencephalographic recording. We also report an excellent response to carbamazepine in subthalamic paroxysmal dyskinesias. © 2003 Movement Disorder Society
