A new device that patients can wear to prevent migraines has just been approved by the FDA.
The device, called Celafly, is worn like a crown around the forehead and works by simulating nerves just above the patients' eyes, creating a tingling sensation, CNN reports.
Studies found that Celafly wearers had two fewer migraines per month, and 38% of users say their migraines have been reduced by 50%. Patients only need to wear the device for 20 minutes a day to see results, and it may be safe to combine with other medications. There are no known side effects. The device does not reduce the intensity of migraines, it just prevents them from happening.
The device is already sold in Canada, where it costs around $250.
