Survival in patients with Parkinson's disease after deep brain stimulation or medical management

Abstract

DBS is associated with a modest survival advantage when compared with a matched group of patients who did not undergo DBS. Whether the survival advantage reflects a moderating influence of DBS on PD or on comorbidities that might shorten life or whether differences may be a result of unmeasured differences between groups is not known. © 2017 International Parkinson and Movement Disorder Society.
