Globus Pallidus Interna or Subthalamic Nucleus Deep Brain Stimulation for Parkinson Disease

Selection of the best deep brain stimulation (DBS) target-subthalamic nucleus (STN) or globus pallidus interna (GPi)-for treatment of motor complications in Parkinson disease remains a matter of debate.Increasing evidence from randomized clinical trials indicates that motor benefit is similar between both targets, including an effect on dyskinesia and improvement in quality of life. Deep brain stimulation of the STN offers consistently greater...
