Throughout their lives, women experience significant changes in their headache patterns that are directly related to changes in their reproductive cycles. Menarche, menstruation, oral contraceptives, pregnancy, and menopause affect migraine through changing levels of sex hormones. As many as 60% of women with migraine report increased attacks at the time of menses, while a smaller percentage experiences migraine exclusively during menstruation. The highest prevalence of migraine in women occurs between the ages of 25 and 55 ---- a woman's most productive years. Furthermore, women in their thirties tend to have an increase in the frequency and severity of their attacks. Women with migraine are also more likely than men to suffer severe functional disability and impairment in quality of life. As a result of its prevalence and impact, migraine is one of the most important issues in women's health.
