Abstract

We aimed to provide evidence that subthalamic nucleus (STN) deep brain stimulation (DBS) is an effective and safe treatment option for older patients with Parkinson's disease (PD). Bilateral STN DBS was performed in 55 patients with PD from 2012 to 2016 at Samsung Medical Center. We divided them into two groups based on the age at DBS: younger group (<65 years, n = 38) and older group (≥65 years, n = 17). For evaluating effectiveness, we compared pre- and post-DBS Unified Parkinson's Disease Rating Scale (UPDRS) part 3 and 4 scores and levodopa equivalent daily dose (LEDD) between the two groups. Additionally, surgery-related complications in each group were assessed. The mean age of the younger group was 56.7 ± 5.7 and that of the older group was 68.5 ± 2.9. More female patients underwent STN DBS in the younger group, but there were no differences in baseline characteristics. In terms of effectiveness, UPDRS part 3 and 4 scores and LEDD significantly improved 6 months after DBS in both groups. In terms of safety, 1 complication was observed in the younger group (2.6%), while 2 complications, including 1 subject with intracerebral hemorrhage, were observed in the older group (11.8%, p = 0.225). Based on our results, STN DBS can...Continue Reading
