Session Title: Parkinson’s Disease: Clinical Trials, Pharmacology And Treatment
Session Time: 1:15pm-2:45pm
Location: Exhibit Hall C
Objective: Comparing motor, cognitive, and psychiatric outcome 5 years after bilateral deep brain stimulation (DBS) of the globus pallidus pars interna (GPi) and the subthalamic nucleus (STN) for advanced Parkinson’s disease (PD).
Background: Previous results from our clinical trial indicated better off-drug phase motor improvement after STN DBS 1 and 3 years after surgery (Odekerken et al., 2016). Additionally, we reported no relevant between-group differences on measures of cognitive and psychiatric functioning 3 years after surgery (Boel et al., 2016).
Methods: Patients were randomized to GPi DBS (n=65) or STN DBS (n=63). Standardized test assessment was performed at baseline, 1 year, 3 years, and 5 years. GPi and STN DBS were compared on UPDRS motor scores, MMSE, and HADS (Hospital Anxiety and Depression Scale) scores 5 years after surgery.
Results: A total of 71 patients completed (at least a part of) the 5-year follow-up, GPi DBS=33 and STN DBS=38. Drop-out rate was not significantly different between the groups (X2; p=0.28). The analyses on UPDRS, MMSE, and HADS scores are currently being performed.
Conclusions: The results of 5-year follow-up data will be presented at the congress.
