Pallidal Deep Brain Stimulation for Parkinson’s Disease
see also Subthalamic deep brain stimulation for Parkinson's disease
GPi and subthalamic nucleus (STN) DBS improve motor function and activities of daily living for Parkinson's disease (PD) patients. Differences in therapeutic efficacy for PD were not observed between the 2 procedures. STN DBS allowed greater reduction in medication for patients, whereas GPi DBS provided greater relief from psychiatric symptoms. An understanding of other symptomatic aspects of targeting each region and long-term observations on therapeutic effects are needed 1).
