This course offers a focused exploration of non-invasive vagal nerve stimulation (nVNS) as a cutting-edge treatment modality for chronic headaches, including migraines and cluster headaches. Participants will delve into the physiological underpinnings of vagal nerve function, its role in pain modulation, and how nVNS leverages these mechanisms to provide relief from chronic headache conditions. Through a blend of theoretical knowledge and practical insights, the course will cover the latest research, clinical trials, patient case studies, and real-world applications of nVNS technology.Designed to deepen understanding of this innovative treatment, the course examines the efficacy, safety, and potential side effects of nVNS, comparing it with traditional pharmacological approaches. It also addresses the practical aspects of implementing nVNS in clinical settings, including patient selection criteria, device operation, and treatment protocols. Participants will gain a comprehensive perspective on how nVNS can be integrated into broader treatment strategies for chronic headache disorders.
