Increased nitroglycerin-mediated vasodilation in migraineurs without aura in the interictal period.

Purpose: Migraine is associated with vascular disorders, but the underlying mechanism is unknown. Nitric oxide (NO) sensitivity is believed to play a major role in migraine pathophysiology. We investigated flow-mediated vasodilatation (FMD) and nitroglycerin-mediated vasodilatation (NMD) of the brachial artery by means of a key molecular mediator, NO, in patients with migraine without aura in the interictal period whether the abnormality is found.
