Neurostimulation to the Vagus Nerve for the Reduction in Frequency of Seizures Associated With Epilepsy

The purpose of the study is to determine the effects of non-invasive vagus nerve stimulation for the reduction in frequency of seizure associated with epilepsy in subjects 18 or older. Subjects will record 4 weeks of baseline seizure activity before being randomized for a period of 8 weeks to receive and active treatment to an active-sham treatment. All subjects will then receive another 8 weeks of active treatment.
