What Is a Vagus Nerve Stimulator (VNS)?

If antiseizure medications are unsuccessful in reducing the frequency and severity of seizures, the implantation of a Vagus Nerve Stimulator (VNS) might be recommended. In 1998, the Food and Drug Administration approved the VNS for patients who have intractable epilepsy. About the size of a pacemaker, a VNS sends programmed electrical signals to the vagus nerve in the neck, stimulating the nerve and thus helping to prevent epileptic seizures.
