(1st May, 2014); At the AAN meeting in Philadelphia, two separate studies showed that electroCore’s non invasive vagus nerve stimulation (nVNS) therapy was effective in helping patients with different types of migraine. The first poster presentation, on April 28th, found that two hours after treatment with electroCore’s nVNS therapy patients who had both chronic migraine and medication overuse headache were pain free in 33% of attacks while significant pain relief (mild or no pain) was noted in 50% of attacks. In the second poster presented on May1st it was found that 45 % of patients, with migraine without aura, were pain free within 30 minutes of just one dose of nVNS therapy.
