Vagus nerve stimulation is a substitute therapy for a patient with multifocal epilepsy and major depression. It is also useful in treating Alzheimer’s disease, obesity, and other neuropsychiatric disorders. Initial VNS requires general anesthesia, and patients with other implant devices may require anesthesia in surgical procedures.
Vagus nerve stimulation is a medical treatment that uses an electrical impulse in the vagus nerve. The vagus nerve is one of the 12 pairs of cranial nerves that arise in the brain that is part of the autonomic nervous system, which controls automatic body functions. This nerve passes through the neck as it goes between the chests and abdomen and to the lower part of the brain, whereas it is connected in the motor function of the voice box, diaphragm, heart, and sensory functions.
