Migraine headaches are one of the most common problems seen in emergency departments and doctors' offices. Migraines are due to changes in the brain and surrounding blood vessels.
Migraine headaches typically last from 4-72 hours and vary in frequency from daily to fewer than 1 per year. Migraine affects about 15% of the population. Three times as many women as men have migraines. More than 80% of people with migraines (called migraineurs) have other members in the family who have them too.
