How Transcutaneous Nerve Stimulators Prevent Migraines
The Cefaly device, available by prescription, is a way to prevent migraine headaches approved by the Food and Drug Administration. The headband, which is made of plastic, is worn with the electrode on the center of your forehead over the eyes where it stimulates branches of a nerve associated with migraines which is known as the trigeminal nerve.
Cefaly is a battery-powered tiara-like device designed to stimulate nerves and prevent headaches, though it must be noted that when migraines do happen they are not less severe. It does not have any known side effects. The device is expected to cost around $250 and it is made by STX-MED .

Migraine Study in Belgium
A study of sixty seven sufferers in Belgium showed that people who used the device, compared to a placebo group, had fewer migraine days monthly and also used less medication. While there are many prescription and over the counter medicines available for people who suffer from these headaches, some people may have adverse reactions to drugs that make them unpalatable over time.
As an alternative to migraine drugs, the device appears to work best when it is used twenty minutes per day. According to literature, chronic attacks were reduced by at least two per month, and some people reported half as many attacks. It can be best contrasted to implantable neurostimulation, which involves some surgery and the fear of an electrical device being installed in close proximity to your brain.
