Thalamic Deep Brain Stimulation for Neuropathic Pain: Efficacy at Three Years' Follow-Up

Abstract BACKGROUND: Deep brain stimulation (DBS) at the internal globus pallidus (GPi) has replaced ablative procedures for the treatment of primary generalized dystonia (PGD) because it is adjustable, reversible, and yields robust clinical improvement that appears to be long lasting. OBJECTIVE: To describe the long-term responses to pallidal DBS of a consecutive series of 22 pediatric patients with PGD. METHODS: Retrospective chart review of 22 consecutive PGD patients, ≤21 years of age treated by one DBS team over an 8-year period. The Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) was used to evaluate symptom severity and functional disability, pre- and post-operatively. Adverse events and medication changes were also noted. RESULTS: The median follow-up was 2 years (range, 1-8 years). All 22 patients reached 1-year follow-up; 14 reached 2 years, and 11 reached 3 years. The BFMDRS motor subscores were improved 84%, 93%, and 94% (median) at these time points. These motor responses were matched by equivalent improvements in function, and the response to DBS resulted in significant reductions in oral and intrathecal medication requirements after 12 and 24 months of stimulation. There were no hemorrhages or neurological complications related to surgery and no adverse effects from stimulation. Significant hardware-related complications were noted, in particular, infection (14%), which delayed clinical improvement. CONCLUSION: Pallidal DBS is a safe and effective treatment for PGD in patients <21 years of age. The improvement appears durable. Improvement in device design should reduce hardware-related complications over time.

Pain from Parkinson's disease (PD) is a non-motor symptom affecting the quality of life and has prevalence of 20–80%. However, it is unclear whether subthalamic nucleus deep brain stimulation (STN–DBS), a well-established treatment for PD, is effective forPD-related pain. Thus, the objective of this meta-analysis was to investigate the efficacy of STN-DBS on PD-related pain and explore how its duration affects the efficacy of STN-DBS. A systematic search was performed using PubMed, Embase, and the Cochrane Library. Nine studies included numerical rating scale (NRS), visual analog scale (VAS), or non-motor symptom scale (NMSS) scores at baseline and at the last follow-up visit and therefore met the inclusion criteria of the authors. These studies exhibited moderate- to high-quality evidence. Two reviewers conducted assessments for study eligibility, risk of bias, data extraction, and quality of evidence rating. Random effect meta-analysis revealed a significant change in PD-related pain as assessed by NMSS, NRS, and VAS (P <0.01). Analysis of the short and long follow-up subgroups indicated delayed improvement in PD-related pain. These findings (a) show the efficacy of STN-DBS on PD-related pain and provide higher-level evidence, and (b) implicate delayed improvement in PD-related pain, which may help programming doctors with supplement selecting target and programming.Systematic Review Registration: This study is registered in Open Science Framework (DOI: 10.17605/OSF.IO/DNM6K).

Objectives. Deep brain stimulation (DBS) is a safe and effective alternative treatment of some movement disorders such as Parkinson's disease. Although DBS is an effective treatment for Parkinson's disease, because of the necessity of surgical intervention, follow-up and the effects on symptoms, this study was carried out to determine the challenges, expectations and accomplishments of patients with DBS in Parkinson’s disease.Materials and Methods. This qualitative study was carried out at the Neurosurgery Department of a research hospital in Turkey with seven patients who underwent DBS between 2008 and 2018. In the study, the challenges, expectations, and accomplishments of patients were investigated by using three focus group interviews in October 2018.Results. Among the participants, six patients were male, and one patient was female. The mean age of the patients was 56.85}16.48. Three main themes were revealed in the study. These were (1) Reborn; decrease in dependence, sense of accomplishment, enjoyment of life, (2) Prejudice; perceived as severely ill by others and (3) Fear; not being accustomed to the device, loss of device function.Conclusion. The results obtained from this study can be used in the process of adaptation to this process by discussing and evaluating the challenges, expectations and accomplishments of the Parkinson's patient in DBS with healthcare professionals and other patients.
