While others have reviewed the application of DBS earlier in the disease course and the results from EARLYSTIM, we focus on the conceptual, scientific, clinical, ethical, and policy issues that arise regarding the recent FDA approval.APS=atypical parkinsonian syndromes; BMT=best medical treatment; DBS=deep brain stimulation; FDA=Food and Drug Administration; GPi=globus pallidus interna; PD=Parkinson disease; STN=subthalamic nucleus
