For patients with multiple sclerosis (MS), vagus nerve stimulation (VNS) has become a cutting-edge therapeutic strategy for treating treatment-refractory cerebellar tremor and dysphagia. This study assesses available data demonstrating the effectiveness of VNS in reducing these incapacitating symptoms, which significantly impact patients’ quality of life. Research indicates that VNS can lead to substantial improvements in dysphagia and cerebellar tremors within two to three months of therapy initiation. Primary outcomes include a reduced severity of symptoms and an enhanced health-related quality of life (HRQoL). Although VNS presents fewer risks than traditional treatments, potential complications exist. Overall, VNS shows promise as an adjunctive therapy for managing dysphagia and cerebellar tremors in MS patients; further research is necessary to explore its long-term effects and applications in other neurological conditions.
