Since chronic migraine is difficult to treat and often associated with medication overuse, non-invasive neurostimulation approaches are worth investigating. Transcutaneous supraorbital neurostimulation using the Cefaly(®) device is promising as a non-invasive preventive treatment for episodic migraine, but no data are available for chronic migraine. Our aim was to perform a preliminary evaluation of the efficacy of the Cefaly(®) device for the prophylaxis of chronic migraine with or without medication overuse. Primary endpoints were 50% reduction in monthly migraine days and 50% reduction in monthly medication use over 4 months. In an open-label study, twenty-three consecutive headache center patients with chronic migraine, diagnosed according to International Headache Society criteria, were recruited prospectively. After informed consent, patients were trained to use Cefaly(®) and instructed to use it for 20 min daily over 4 months. All patients received active neurostimulation. Thirty-five percent of the patients enrolled in the study achieved the study endpoints. Over half the patients had a greater than 50% reduction in acute medication consumption.
