Vagus nerve stimulation (VNS) represents an innovative technological advancement that offers hope to numerous patients with neurological disorders who derive limited benefits from existing treatment options. Originally developed for the management of epilepsy, the VNS device has expanded its applications and is now employed in the treatment of conditions such as depression, pain, and even Alzheimer's disease. The underlying mechanism of VNS is relatively straightforward: it transmits electrical impulses via the vagus nerve, influencing various physiological functions, including heart rate, digestion, and mood regulation.
