Vetvik KG, et al. - Researchers explored the association of menstrual migraine (MM) with premenstrual syndrome (PMS) by comparing self-reported PMS-symptoms in female migraineurs from the general population with and without MM without aura. In 2011/2012, a neurologist invited women with self-reported migraine in ≥ 50% of their menstruations and < 180 headache days during the preceding year to conduct a semi-structured interview. The interview focused on headache and migraine, migraine treatment, menstrual symptoms, and use of hormonal contraception. Each participant was also asked to complete a self-administered form containing 11 questions about PMS-symptoms adapted from the Diagnostic and Statistical Manual of Mental Disorders. Outcomes suggest that migraineurs with and without MM were not different in the number of self-reported PMS-symptoms. Women with MM displayed significantly higher Headache Impact test scores, more migraine days per month, and longer duration of migraine attacks, while the groups were similar in terms of Migraine Disability Assessment Score results.
