Headband designed to fight migraines
A device meant to help migraine sufferers has just been approved by the FDA.
It's a headband called Cefaly. You get it with a prescription and wear it over your forehead for 20 minutes a day. The battery-powered device delivers small impulses to the nerves.
In a study published in the journal "Neurology" last month, researchers say Cefaly reduced the number of chronic migraine attacks on average by two per month, though it did not appear to reduce the severity of attacks.
