Benefits of Deep Brain Stimulation for Early Stage Parkinson Disease

Deep brain stimulation (DBS) can decrease the risk for disease progression as well as the need for and complexity of medications in patients with early-stage Parkinson disease (PD) compared with optimal medical therapy alone, according to study results published in Neurology. Previous studies reported the benefits of DBS in mid- and advanced-stage PD, but there are limited data on the long-term safety and efficacy of DBS in early-stage PD.
