Migraines in Women: A Focus on Reproductive Events and Hormonal Milestones

Abstract

Migraine, a prevalent neurological disorder, is more common in women than in men. This sex difference is more pronounced after menarche and diminishes after menopause. Migraines in women are influenced by the menstrual cycle, pregnancy, and lactation, suggesting a connection to sex hormones, known as the estrogen withdrawal theory. Beyond endogenous hormonal changes accompanying reproductive events, exogenous hormonal factors such as contraceptives or hormone replacement therapy may also affect migraines. The hormonal influence cannot be explained simply by serum estrogen levels; instead, it involves a complex interplay of various factors. Here, we delineate aspects of migraines associated with endogenous and exogenous hormonal changes over the course of a woman’s life, exploring the mechanisms and contributing factors through which sex hormones influence migraines.
