Sex-hormone-related events in migrainous females. A clinical comparative study between migraine with aura and migraine without aura

Abstract

In this study, the relationship between hormonal-related events and migraine with aura (MA) and without aura (MO) was investigated. Subjects included 268 women suffering from MA (88) and MO (180). Data were collected on the relationship between sex-hormone-related events and migraine. Migraine during menses was observed in a significantly higher percentage of MO than MA patients (p < 0.03). Menstrual migraine was significantly more common in MO than in MA patients (p < 0.01). Migraine began during pregnancy in a significantly higher percentage of MA than of MO patients (p < 0.01). No significant difference was observed between the two groups of patients regarding the onset of migraine at menarche, after menopause, in the postpartum period or during the early cycles of oral contraceptives. Also, both groups of patients showed a similar migraine course during pregnancy, oral contraceptive use and menopause. Eight patients with coexisting migraine with aura and migraine without aura attacks reported the appearance of the aura symptom for the first time in the early cycles of oral contraceptive intake. These findings suggest that gonadal hormone fluctuation may influence both types of migraine.
