Systemic Endothelial and Arterial Changes in Migraineurs : A Review of Literature

Migraine is a common, primary, chronic-intermittent neurovascular headache disorder that is a risk factor for developing cardiovascular diseases and stroke. Recent methodological approaches for measurement of arterial or endothelial function have been advanced. Endothelial dysfunction and arterial changes could be evaluated by non-invasive techniques. These non-invasive methods include ultrasound examination, arterial tonometry, plethysmography and magnetic resonance angiography. Whether migraineurs had abnormal findings of endothelial dysfunction and the arterial changes in the cranial and the peripheral artery system has been debated in previous literature. Herein we aimed to introduce widely used non-invasive techniques to measure vascular function, and also to review the literature of endothelial function and arterial findings in migraine patients.
