Session Title: Quality Of Life/Caregiver Burden in Movement Disorders
Session Time: 1:45pm-3:15pm
Location: Hall 3FG
Objective: To detect the related factors and possible predictors to QoL improvement for those PD patients one year after STN DBS.
Background: Subthalamic deep brain stimulation (STN DBS) has been reported to improve the quality of life (QoL) related to Parkinson’s disease (PD). However, not all subjects are satisfied with the postsurgical QoL outcome.
Methods: 45 PD patients with bilateral STN DBS surgery were included and followed up for 1 year. The Reliable Change Index (RCI) was adapted to determine the individual postsurgical QoL outcome. The changes of QoL were correlated with baseline parameters and the changes of progression parameters using Pearson’s correlation. The exploratory stepwise regressions were adopted to detect the extents of baseline variables and progression parameters. The predictors to QoL outcome were detected using the logistic regression analysis.
Results: 51.1% of the patients reported a better QoL, 40.0% of patients reported an unchanged QoL, while 8.9% of patients reported a worsening of QoL. The subdomains of mobility, activity of daily living, cognition, and bodily discomfort improved significantly after the surgery. The presurgical factors including QoL, dopaminergic medication burden, disease stages, depression scores and postsurgical reductions in depression and non-motor scores were found to correlate with QoL changes. Furthermore, the greater presurgical QoL burden, lesser dopaminergic medication exposure and earlier disease stages were predictors to QoL improvements.
Conclusions: The clinicians should carefully evaluate the non-motor symptoms and quality of life in those patients at relatively earlier stages and with lower medicine dosage to get more successful DBS outcomes.
