Show moreObjective: In this prospective cohort study, characteristics of perimenstrual and non-perimenstrual migraine attacks in women were compared with migraine attacks in men.Background: Women report longer migraine attacks and more accompanying symptoms than men in cross-sectional questionnaire studies, but this has not been confirmed in longitudinal studies. Supposed differences could result from different characteristics specific to perimenstrual migraine attacks, or of attacks in women in general.Methods: This cohort study was performed among patients with migraine who were treated at the Leiden Headache Clinic. We assessed differences in migraine attack characteristics between men and women who were prospectively followed by a previously validated electronic headache diary. The primary outcome was "attack" duration. Differences between perimenstrual (Days -2 to +3 of the menstrual cycle) and non-perimenstrual attacks in women versus attacks in men were corrected for age, chronic migraine, and medication overuse headache.Results: A total of 1347 women and 284 men were included, reflecting the preponderance of women in migraine prevalence. Crude median (first and third quartile [Q1-Q3]) attack duration in men was 32.1 [17.7-53.6] h, compared to 36.7 [21.9-62.4] h for non-perimenstrual migraine attacks and 44.4 [17.9-79.0] h for perimenstrual migraine attacks in women. After correction for confounding, perimenstrual migraine attacks were 1.62 (95% confidence interval [CI] 1.47-1.79; p < 0.001) and non-perimenstrual 1.15 (95% CI 1.05-1.25; p = 0.003) times longer compared to migraine attacks in men. The mean relapse percentage in men was 9.2%, compared to 12.6% for non-perimenstrual migraine attacks, and 15.7% for perimenstrual migraine attacks. Relapse risk was greater for perimenstrual (odds ratio [OR] 2.39, 95% CI 1.93-2.95; p < 0.001), but not for non-perimenstrual (OR 1.18, 95% CI 0.97-1.45; p = 0.060) attacks. Migraine attacks in women were more often accompanied by photophobia, phonophobia, and nausea, but less often aura.Conclusion: Compared to attacks in men, both perimenstrual and non-perimenstrual migraine attacks are of longer duration and are more often accompanied by associated symptoms. A sex-specific approach to migraine treatment and research is needed. Show less

Show moreObjective: To assess validity of ICHD-3 diagnostic criteria for menstrual migraine.Methods: We performed a longitudinal E-diary study in premenopausal women with migraine. Menstrual migraine diagnosis was self-reported at baseline, and verified according to diary based ICHD-3 criteria and a previous proposed statistical model. Validity of self-reported menstrual migraine was compared to diary based diagnosis and statistical diagnosis. Test-retest reliability and concordance between both methods were determined. Clinical characteristics of perimenstrual and non-perimenstrual migraine attacks were compared in women with and without menstrual migraine.Results: We included 607 women. Both women who did and women who did not self-report to suffer from menstrual migraine fulfilled ICHD-3 criteria in the E-diary in two thirds of cases. Pure menstrual migraine was extremely rare (<1%). Concordance between statistical and diary based diagnosis was minimal (kappa = 0.28, 95% CI:0.23-0.33). Women diagnosed with menstrual migraine showed 37-50% longer attack duration and increased triptan intake (OR 1.19-1.22, p<0.001) during perimenstrual attacks.Conclusion: Self-reported menstrual migraine diagnosis has extremely poor accuracy. Two thirds of women suffer from menstrual migraine, independent of self-reports. Pure menstrual migraine is rare. Women with menstrual migraine have longer attack duration and increased triptan intake during perimenstrual attacks, in contrast to women without menstrual migraine. Prospective headache (E-)diaries are required for a menstrual migraine diagnosis, also in clinical practice. Show less

Show moreBackground: The relationship between migraine and depression has been thoroughly investigated, indicating a bidirectional comorbidity. The exact temporal relationship between acute depressive symptoms (mood changes) and the various phases of the migraine attack has not yet been examined. Methods: We performed a prospective diary study in n = 487 participants with migraine. Participants filled out a daily diary on migraine and acute depressive symptoms during a 1-month period. We randomly selected one migraine attack per participant, consisting of six days around an attack, including the interictal, premonitory, ictal, and postdromal phases. Acute depressive symptoms covered five major items from the DSM-5 classification. Primary analysis was performed using a mixed model with post-hoc testing. We also tested whether lifetime depression influenced the presence of acute depressive symptoms. Results: During a migraine headache day, patients scored higher on acute depressive symptoms than on all other days of the migraine attack (p < 0.001). There were no early warning signs for an upcoming headache attack through acute depressive symptomatology. Migraine patients with lifetime depression scored overall higher during the migraine attack than those without lifetime depression (p < 0.001). Limitations: Migraine attacks were based on self-reported migraine and one migraine attack per patient was randomly selected.Conclusion: We now clearly demonstrate that during the migraine headache phase, but not in the prodromal phase, patients report increased depressive symptomatology. No evidence was found for mood changes as an early warning sign for an upcoming migraine attack. Show less
