A 13-year-old girl presented with refractory secondary generalized focal epilepsy. Vagal nerve stimulator was implanted because of drug-resistant epilepsy. After the increase of vagal nerve stimulator current output to a relatively high level, the patient experienced seizure aggravation and status epilepticus. We conclude that vagus nerve stimulation may induce paradoxical seizures and may lead to status epilepticus, similarly to some antiepileptic drugs.
