End of day dyskinesia in advanced Parkinson's disease can be eliminated by bilateral subthalamic nucleus or globus pallidus deep brain stimulation



We report the therapeutic effects of deep brain stimulation (DBS) in 2 patients with Parkinson's disease (PD) with severe end of dose dyskinesia that was resistant to medical therapy. In both patients, severe, end of day ballistic dyskinesias occurred when the last levodopa dose of the day was wearing off. Globus pallidus (GPi) DBS in 1 case and subthalamic (STN) DBS in the second case produced full resolution of end of day dyskinesia. © 2006 Movement Disorder Society
