In the complex realm of our physiology, the vagus nerve stands as a silent orchestrator, influencing health and disease in ways that have long been underestimated. Vagus Nerve Stimulation delves into the profound significance of this 10th cranial nerve, tracing its course through the body and illuminating its role as a vital component of the parasympathetic nervous system. This comprehensive reference, contributed by leading experts at the forefront of medical science, unveils the groundbreaking field of vagus nerve stimulation—a non-invasive approach to harness the body's innate potential for health optimization, inflammation control, and disease modification. Contributed by leading experts in the field, this comprehensive volume serves as a compendium of current knowledge about stimulating the vagus nerve in many different disease states. This book starts with the foundational insights in Basic Science and Technical Considerations. From there, it continues to Neurologic Conditions, where chapters explore applications for epilepsy, cluster headaches, and concussions. Evolving Therapy for Neurologic Conditions introduces cutting-edge treatments for acute ischemic stroke, synaptic plasticity, and neurodegenerative disorders. The book extends into Psychiatric and Somatic Conditions, providing insights into anxiety, depression, addiction disorders, and more. Conventional Inflammatory Conditions shed light on vagus nerve stimulation's role in combatting sepsis, immune-mediated inflammatory diseases, and metabolic syndrome, among others. Concluding with a foray into Oncology, the book highlights the potential of vagus nerve stimulation in addressing the lingering effects of long covid and migraine. With an authoritative blend of scientific rigor and practical application, this reference serves as an indispensable guide to the vast landscape of vagus nerve stimulation, transforming our understanding of health and wellness.
