Menstrual migraine is a type of migraine that typically starts three days before a menstrual period but can last for the duration of the period. Some may experience these episodes sporadically, while others may suffer monthly attacks. A woman’s oestrogen and progesterone levels drop dramatically in the days preceding a period and, in turn, this plummet of hormones can induce a migraine attack. The fluctuation of hormones can be very disruptive to the migraine brain and many female migraine sufferers may notice an increase in attacks throughout puberty and during perimenopause, when hormone levels are less stable.
