Introduction: Deep brain stimulation (DBS) is an effective therapy for Parkinson's disease (PD). However, its effect in older patients is not extensively studied, as they are often excluded from DBS surgery due to concerns of complications or reduced benefit. We assessed clinical outcomes after subthalamic nucleus (STN) DBS in older patients (age > 75 years) with PD. Methods: All PD patients above 75 years who underwent STN-DBS between 1999 and 2015 were included. Unified Parkinson's Disease Rating Scale (UPDRS) scores and Parkinson's Disease Questionnaire (PDQ-39) scores were assessed up to 4 years after surgery. Other measures included were complications/adverse events, levodopa equivalent dose, and cognitive function. Results: A total of 30 patients underwent 52 lead placements. Mean age at surgery was 77.5 years (range 75.0-84.5 years). Post-DBS, motor scores improved by 30.8% after 1-year and 27.3% after a mean of 2.5 years (p < .001). All motor sub-scores improved, however axial signs did not change over time. OFF time and dyskinesia duration reduced significantly (p < .001), whereas quality of life, activities of daily living and cognitive function did not significantly change. The following adverse events were noted: transient post-operative confusion (36% of patients), gait difficulty (13.3% of patients), hemorrhage (3.8% of leads), personality changes (3.3% of patients), lead revision (1.9% of leads), seizure (1.9% of leads), and infection (1.9% of leads). Conclusions: STN-DBS improves motor outcomes in patients over 75 years of age; however, there was no change in quality of life. Although post-surgical transient confusion was common, there were no serious adverse events and the incidence of other complications was typical for DBS surgery.
