What Is Vagus Nerve Stimulator Therapy?

Vagus nerve stimulator (VNS) therapy is a treatment for epilepsy. The vagus (VAY-gus) nerve runs up the sides of the neck and into the brain. The VNS sends electrical pulses to the nerve, which carries the pulses to the brain. This helps prevent or shorten the length of seizures.
