The FDA has just approved a new device designed to prevent migraine headaches. The headband from Belgium uses transcutaneous electrical nerve stimulation, abbreviated TENS, to ward off migraines. The plastic, battery-powered headband contains an electrode situated just above the eyes so that the low-intensity electrical current reaches the trigeminal nerve.
With no more than 20 minutes a day of use, the device reduces the number of migraines patients experience by roughly two per month. The Cefaly, as it is called, is already approved in Europe and Canada. Side effects include a tingling sensation where the electrode meets the skin. Other complaints include drowsiness while the device is in use or headache after the 20 minute sessions.
