Approximately 2.5% of patients with episodic migraine develop chronic migraine. Hormones. Phenome-wide analysis highlights putative causal relationships between self-reported migraine and other complex traits. In the ARC, energy homeostasis is controlled by orexigenic neuropeptides [stimulating (+) food intake and decrease energy expenditure] neuropeptide Y (NPY) and agouti-related peptide (AgRP) and anorexigenic peptides [inhibit (−) food intake and increase energy expenditure] proopiomelanocortin (POMC) and cocaine and amphetamine-regulated transcript (CART). These include direct PVN projections to the trigeminocervical complex (TCC), VMH projections to the periaqueductal grey (PAG) and the locus coeruleus (LC), and indirect communication through the ventral tegmental area (VTA) and nucleus tractus solitarius (NTS). Pathophysiology of migraine 1. 3. Imaging studies in the migraineurs' brain interictally demonstrate there is reduced activation of the spinal trigeminal nuclei in response to trigeminal nociceptive stimulation, which normalizes prior to the next migraine attack. Migraine and epilepsy are comorbid episodic disorders that have common pathophysiologic mechanisms. Migraine attacks, like epileptic seizures, may be triggered by excessive neocortical cellular excitability; in migraine, however, the hyperexcitability is believed to transition to cortical spreading depression rather than to the hypersynchronous activity that characterizes seizures. Migraine; aura; cortical excitability; cortical spreading depression; trigeminovascular system.

This theory proposes that migraine results from depolarization of cortical neurons followed by a reduction in posterior cerebral blood flow. The pathophysiology of migraine is not fully understood. Projections to and from specific nuclei within the hypothalamus are involved in the complex neural circuitry of energy homeostasis, including the arcuate (ARC), paraventricular (PVN), ventromedial (VMH), dorsomedial (DMH), and lateral (LH) hypothalamic neurons. Pain is often unilateral, throbbing, worse with exertion, and accompanied by symptoms such as nausea and sensitivity to light, sound, or odors. See this image and copyright information in PMC. But, based on what we currently know, the cause of migraines can be summed up like this: A migraine occurs when a genetically susceptible person in a vulnerable state experiences a trigger.
