Peripheral Neuromodulation for the Management of Headache.

Anesth Pain Med 2020 Dec 30;10(6):e110515. Epub 2020 Nov 30.

Department of Anesthesiology, LSU Health Shreveport, Shreveport, LA, USA.

Context: Neuromodulation is an expanding field of study for headache treatment to reduce pain by targeting structures within the nervous system that are commonly involved in headache pathophysiology, such as the vagus nerve (VNS), occipital nerves, or sphenopalatine ganglion (SPG) for stimulation. Pharmaceutical medical therapies for abortive and prophylactic treatment, such as triptans, NSAIDs, beta-blockers, TCAs, and antiepileptics, are effective for some individuals, but the role that technology plays in investigating other therapeutic modalities is essential. Peripheral neuromodulation has gained popularity and FDA approval for use in treating certain headaches and migraine headache conditions, particularly in those who are refractory to treatment.

Mechanism of action of non-invasive cervical vagus nerve stimulation for the treatment of primary headaches.

Am J Manag Care 2017 Nov;23(17 Suppl):S312-S316

Stimulation of the cervical vagus nerve with implanted vagus nerve stimulation (iVNS) has been used clinically for more than 20 years to treat patients with epilepsy. More recently, a non-invasive cervical vagus nerve stimulation (nVNS), gammaCore, was developed, which has been purported to also stimulate the vagus nerve without the cost and morbidity associated with an iVNS system. gammaCore has been used to acutely treat various types of primary headaches, including migraine and cluster headaches (CH), and for the prevention of episodic, chronic, and menstrual migraines and CH.
