Randomized Controlled TrialDeep brain stimulation in early Parkinson's disease: enrollment experience from a pilot trial.
Deep brain stimulation (DBS) of the subthalamic nucleus is an accepted therapy for advanced Parkinson's disease (PD). In animal models, pharmacologic ablation and stimulation of the subthalamic nucleus have resulted in clinical improvement and, in some cases, improved survival of dopaminergic neurons. DBS has not been studied in the early stages of PD, but early application should be explored to evaluate safety, efficacy, and the potential to alter disease progression. ⋯ This report demonstrates that subjects with early stage PD can be successfully recruited, consented and retained in a long-term clinical trial of DBS. Our ongoing pilot investigation will provide important preliminary safety and tolerability data concerning the application of DBS in early stage PD.
