Migraine Headaches Associated with the Menstrual Cycle

Up to 25% of women experience migraine headaches during their reproductive years; often migraine headaches may be triggered or exacerbated by hormonal changes. It has been estimated that 7-14% of women experience migraines only during the premenstrual or menstrual phase of their cycles. Another 52-70% experience headaches throughout the month but note increased headache activity before or during menses.
