Migraine Headache Overview
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 to 72 hours and vary in frequency from daily to fewer than one per year. According to the National Headache Foundation, more than 29.5 million Americans suffer from migraine, and it affects three times as many women as men. About 70% to 80% of people with migraines (called migraineurs) have other members in the family who have them too.
