Recent clinical and preclinical results using electroCore’s non-invasive vagus nerve stimulation (nVNS, gammaCore) therapy in the treatment and prevention of primary headache are the subject of seven presentations at the American Headache Society Science Meeting being held at San Diego on June 9 to 12, 2016.
The seven accepted abstracts are based on work conducted at universities across the U.S. and Europe. They report on how nVNS is effective for many patients in preventing cluster headache attacks, decreasing the number of menstrual migraines and providing additional preclinical and clinical data that further demonstrates how nVNS may work.
The platform presentations are:
- “Does Non-invasive Vagus Nerve Stimulation with gammaCore Acutely Normalize Habituation of Visual Evoked Potentials in Migraine Patients?” Institutions involved: Headache Research Unit, Department of Neurology and University of Liège, Belgium. Presentation on June 10, from 11:45 a.m. to 1:15 p.m.
- “Non-invasive Vagus Nerve Stimulation for Chronic Cluster Headache: Effects on Attack Frequency Over Time and Response Rates.” Institution involved: The Migraine and Headache Clinic, Konigstein, Germany on behalf of the PREVA Study Group. Presentation on June 11, from 10:30 a.m. to 12:30 p.m.
- “Vagus Nerve Stimulation Inhibits Acute Intracranial Dural-Nociceptive Activation of Central Trigeminovascular Neurons.” Institution involved: The Department of Maxillofacial pathology and Radiology and Medicine, NY University College of Dentistry. Presentation on June 11, from 2:00 p.m. to 3:30 p.m.
- “Vagal Nerve Stimulation Suppresses Activation of Trigeminal Nociceptive Neurons in an Animal Model of Migraine Involving Trigeminal Sensitization.” Institution involved: The Centre for Biomedical and Life Sciences, Missouri State University. Presentation on June 11, from 2:00 p.m. to 3:30 p.m.
