The results of two studies, presented at the American Headache Society (AHS) Science Meeting last weekend in San Diego, show that using electroCore’s non-invasive vagus nerve stimulation (nVNS) therapy, gammaCore, is effective at preventing both cluster headache and menstrual migraine.
Cluster headache is considered one of the most painful conditions known to medical science with more than 350,000 patients in the U.S., and approximately 100,000 patients in the UK, suffering from this debilitating condition. Menstrual and menstrually related migraine sufferers form one the largest distinct subgroups of migraine patients, and it is generally considered to be one of the most resistant to existing treatments.
New results from the PREVA study, a randomized, prospective, controlled study of nVNS for the prevention of chronic cluster headache, was led by Dr. Charly Gaul from the Migraine and Headache Clinic, in Konigstein, Germany.
The study found that as early as two weeks after adding gammaCore therapy to the standard of care, patients had a significant and sustained reductions in cluster headache attack frequency. This was also associated with significantly greater than 25%, 50% and 75%, response against standard of care.
Researchers from the Headache Center, Carlo Besta Neurological Institute and Foundation, Milan, Italy, the Headache and Pain Unit, Istituti di Ricovero e Cura Carattere Scientifico, San Raffaele Pisana, Rome, Italy, and the Carolina Headache Institute presented the results of their open-label pilot study of nVNS for the prevention of menstrual migraine and menstrually-related migraine.
The study found that prophylaxis with nVNS was effective in significantly reducing the number of menstrual migraine/menstrually related migraine days per month as well as pain intensity, analgesic use and migraine disability. These findings demonstrate that nVNS may be an effective and safe preventative measure against menstrual and menstrually related migraine. There are currently no specifically approved therapies for menstrual migraine.
“This is a significant result for the many millions of women who suffer from this debilitating condition on a monthly basis,” said Dr. Grazzi from the Headache centre at the Carlo Besta Neurological Institute in Milan Italy who led the study. “The treatment, which is self-administered by the patient using a gammaCore device, is easy to use and without any significant side effects.”
