Rationale: Approximately a third of patients with epilepsy have drug-resistant epilepsy (DRE). For patients with DRE, vagal nerve stimulation (VNS) is a minimally invasive treatment option, especially for patients who are not candidates for resective epilepsy surgery. The goal of this study is to identify patients for whom VNS is more likely to provide meaningful seizure improvement.
Methods: We retrospectively reviewed 161 patients who underwent VNS implants for their refractory epilepsy. Both generalized and focal epilepsy patients were included. After excluding patients with VNS therapy <
