ABSTRACT

Transient dyskinesia induced by deep brain stimulation (DBS) for Parkinson’s disease (PD) has previously been reported as an intra-operative side effect usually indicating excellent lead placement and a positive outcome. Generally, stimulation-induced dyskinesia occurs contralateral to the side of stimulation. We report a case in which a patient developed a severe bilateral “dyskinetic storm” upon placement of the cannula and prior to macrostimulation during DBS surgery of the left subthalamic nucleus. This case illustrates that rarely dyskinetic storms may occur intra-operatively and become generalized.
