Fifteen-Year Outcomes of Bilateral Pallidal Stimulation in Isolated Generalized Dystonia: Characterization of Therapeutic Response and Emergence of Parkinsonism.
BACKGROUND Bilateral pallidal deep brain stimulation (GPi-DBS) is effective for dystonia. Long-term evolution of therapeutic benefit and emergence of parkinsonism have not been systematically characterized. OBJECTIVES To assess 15-year dystonia outcomes and characterize parkinsonism after bilateral GPi-DBS. METHODS...
