Deep brain stimulation use in treating multiple sclerosis tremor: A practical approach for meta-analyses

Area of Science:

• Neurology
• Neurosurgery

Background:

• Deep brain stimulation (DBS) is explored as a treatment for tremor in multiple sclerosis (MS).
• Existing studies on DBS for MS tremor lack systematic evidence assessment.
• Zali and colleagues performed the first systematic review and meta-analysis on this topic.

Discussion:

• The meta-analysis by Zali et al. identified significant heterogeneity across studies.
• High variability suggests methodological concerns in pooling diverse research.
• Addressing heterogeneity is crucial for reliable conclusions on DBS efficacy in MS.

Key Insights:

• The first systematic review and meta-analysis on DBS for MS tremor revealed considerable study variability.
• Methodological concerns arise from pooling studies with significant heterogeneity.
• Further research should focus on standardizing methodologies for DBS in MS tremor.

Outlook:

• Future systematic reviews should account for and address heterogeneity.
• Standardized protocols may improve the reliability of DBS efficacy data for MS tremor.
• Refined methodologies will enhance the understanding of DBS as a treatment for MS-related tremor.
