People with migraine appear to be at a greater risk of stroke than the general population, a risk which appears to increase with the frequency of migraine attacks.[Guidetti et al., 2014] Although the mechanisms underlying the comorbidity are not understood, people with migraine should be screened for modifiable vascular risk factors.[Guidetti et al., 2014; Dodick, 2009] Such risk factors include smoking, hypertension, diabetes, and hypercholesterolaemia.[Spalice et al., 2016] Many therapeutic options for migraine are vasoconstrictive agents, making consideration of migraine and CVD comorbidity all the more pertinent.[Spalice et al., 2016]
