Description of intervention(s) / exposure
70 premenopausal women will be allocated to either the menstrual migraine group or the control group. They will attend our clinic for one visit only. We will measure blood pressure and arterial compliance, then fit a headpiece with transcranial doppler (TCD) ultrasound probes to measure blood flow in the brain; this will be monitored while participants perform a hypercapnia test and the N-back test. Participants will complete three questionnaires (MIDAS, HIT-6 and MS-QOL). A blood sample will be obtained to explore gene expression. The visit will take approximately two and a half hours.
Women will be included in the menstrual migraine group if they suffer from migraine/headache +/- 3 days from their period and/or ovulation (mid-cycle) in the previous three menstrual cycles, lasting 4-72 hours with at least two of these characteristics: unilateral location, pulsating or throbbing pain, pain of at least moderate intensity, or aggravated by or causing avoidance of physical activity (walking/stair climbing). They should be free from headache attacks at other times of the cycle.

Statistical methods / analysis
An independent t-test will be used to compare group differences (migraineur vs. non-migraineur) in basal cerebral hemodynamics (mean BFV, PI, RI and cerebrovascular resistance index), CVR to hypercapnia and CVR to N-back test (neurovascular coupling capacity). The associations between cerebrovascular function, headache characteristics such as frequency, severity, average duration of each attack will be examined using linear regression and Bayesian analyses. Correlations between polymorphisms associated with migraine susceptibility (identified by genotypic profiling) and cerebrovascular function will be determined by regression analysis. If possible, we will also determine whether use of oral contraception is associated with headache severity, frequency or duration and impairment of cerebrovascular function using Wald’s test. Estradiol levels may be included as a covariate in the analysis. Adjustment for multiple comparisons will also be made.
