Brief Summary:
Patients with refractory epilepsy who are candidates for a treatment with vagus nerve stimulation will be prospectively randomized into 3 arms with different vagus nerve stimulation paradigms. Vagus nerve stimulation parameters are programmed and adjusted during outpatient clinic visits, within the normal clinical practice.
