title: Rescue GPi-DBS for a Stroke-associated Hemiballism in a Patient with STN-DBS.
abstract: BACKGROUND
  Hemiballism/hemichorea commonly occurs as a result of a lesion in the subthalamic region.
  
  
  METHODS
  A 38-year-old male with Parkinson's disease developed intractable hemiballism in his left extremities due to a small lesion that was located adjacent to the right deep brain stimulation (DBS) lead, 10 months after bilateral subthalamic nucleus (STN)-DBS placement. He underwent a right globus pallidus internus (GPi)-DBS lead implantation. GPi-DBS satisfactorily addressed his hemiballism.
  
  
  CONCLUSIONS
  This case offered a unique look at basal ganglia physiology in human hemiballism. GPi-DBS is a reasonable therapeutic option for the treatment of medication refractory hemiballism in the setting of Parkinson's disease.
