Migraines suck, but do they suck enough that you'd strap on an electric headband that zaps your brain's nerves to block the pain? The FDA doesn't think that's such a crazy notion—the agency just approved exactly such a device for treating and preventing migraine headaches.
Cefaly is an electrical nerve stimulation headband that sends a small, steady electrical current to the trigeminal nerve, the largest of the 12 nerves emerging directly from the brain. The device is the first electric nerve stimulation gadget approved by the FDA for pain prevention as well as treatment.
Does it work? Well, in a randomized study of 67 patients, users wearing the Cefaly headband reported an average of two fewer headache days per month. About half of those wearing the headband reported their number of headache days was cut in half or more. And while the device is brand-new to the U.S. market, it was previously approved for use in Europe and Canada.
Cefaly says that in data they've collected since 2008, only 4.3% of users have experienced mild side effects. Meanwhile, they say, 50% of migraine patients have had severe side effects from the prescription medications they use.
