  Purpose

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.

Primary Outcome Measures:
  • Efficacy of vagus nerve stimulation: responder rates and mean monthly seizure frequency reduction, mean seizure free interval, seizure severity and seizure type [ Time Frame: After 6 and 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • VNS-related side effects [ Time Frame: After 6 and 12 months ] [ Designated as safety issue: Yes ]
