Portable Vagus Nerve Stimulator for Migraine

Portable Vagus Nerve Stimulation (VNS) may be helpful to stop migraine.  A small study of 30 patients was presented at the American Academy of Neurology Annual Meeting 2013 in San Diego that revealed noninvasive VNS can be effective for rescue therapy for both migraine with and without aura.  This was a pilot study and additional information on 24 hour response in this patient group treated with VNS will be published in a forthcoming article.  And, larger controlled trails are currently under way to more completely evaluate the treatment.

VNS is a potentially innovative, non-medicinal therapy and has few side effects.  Lead investigator Peter Goadsby MD of UCSF conducted the study financed by ElectoCor which makes the gamma-Core device use in this analysis.  A 2005 article in Cephalalgia showed relief of migraine  with VNS.  The gamma-core device is an attempt to evaluate and apply VNS technology for migraine therapy.  At our Northshore pain clinic, we are continuously evaluating new technology and procedures.
