Serum Vitamin B12 and Methylmalonic Acid Status in Migraineurs: A Case‐Control Study
Abstract
Although the exact pathophysiological mechanistic pathways that result in the initiation of migraine attacks remain unclear, there are some proposed mechanisms including neurogenic inflammation, trigeminovascular system activation, vascular dysfunction, and augmented release of nitric oxide (NO) and homocysteine (Hcy). Vitamin B12 is thought to be involved in important pathways that seem to be related to the pathogenesis of migraine including scavenging against NO and prevention of hyperhomocysteinemia. Therefore, the aim of the current study was to evaluate the serum vitamin B12 and methylmalonic acid (MMA) status in a group of migraine patients compared to healthy controls.
