Abstrakt:	Objective: The purpose of this study was to investigate how quality of life outcome after bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson's disease (PD) depends on age.Methods: In this prospective, open-label, multicenter study including 120 PD patients undergoing bilateral STN-DBS, we investigated the PDQuestionnaire-8 (PDQ-8), Unified PD Rating Scale-III, Scales for Outcomes in PD-motor examination, complications, activities of daily living, and levodopa equivalent daily dose preoperatively and at 5 months follow-up. Significant changes at follow-up were analyzed with Wilcoxon signed-rank test and Bonferroni correction for multiple comparisons. To explore the influence of age post hoc, the patients were classified into 3 age groups (≤59, 60-69, ≥70 years). Intragroup changes were analyzed with Wilcoxon signed-rank and intergroup differences with Kruskal-Wallis tests. The strength of clinical responses was evaluated using effect size.Results: The PDQuestionnaire-8, Scales for Outcomes in PD-motor complications, activities of daily living, and levodopa equivalent daily dose significantly improved in the overall cohort and all age groups with no significant intergroup differences. However, PDQuestionnaire-8 effect sizes for age groups ≤59, 60 to 69, and ≥70 years, respectively, were strong, moderate, and small. Furthermore, PDQuestionnaire-8 domain analyses revealed that all domains except cognition and emotional well-being significantly improved in patients aged ≤59 years, whereas only communication, activities of daily living, and stigma improved in patients aged 60-69 years, and activities of daily living and stigma in patients aged ≥70 years.Conclusions: Although quality of life, motor complications, and activities of daily living significantly improved in all age groups after bilateral STN-DBS, the beneficial effect on overall quality of life was more pronounced and affected a wider range of quality of life domains in younger patients. © 2017 International Parkinson and Movement Disorder Society.
