Menstrual Migraine

Approximately 10 million women in the US suffer from menstrual migraine, a common and disabling condition. Menstrual migraine is typically defined as a migraine headache that affects a woman each month starting two days before the menstrual period and continuing to the end of menstruation. It differs from nonmenstrual attacks of migraine, even in the same woman, in the regularity of its timing and its greater severity.
