Long-Term Efficacy and Quality-of-Life Changes After Vagus Nerve Stimulation in Adult Patients With Drug-Resistant Epilepsy.

Background And Purpose: There is a current need to understand the efficacy and quality of life (QoL) outcomes of vagus nerve stimulation (VNS). Identifying patients most likely to benefit from VNS could aid in their selection, reduce side effects, and improve outcomes. Here we studied clinical and QoL outcomes after VNS in patients with drug-resistant epilepsy and attempted to identify response predictors.
