Some new technology may bring new hope for migraine sufferers.
An experimental nerve stimulator may help prevent migraines in people who suffer from the intense headaches at least four times a month.
A study in Belgium asked patients to wear a nerve stimulator on their forehead for 20 minutes a day.
The number of days a month with migraines decreased from nearly seven to nearly five.
Doctors said the results are similar to drugs used to prevent migraines but without the potential for medication side effects.
