Migraine is a neurologic disorder characterized by head pain jointed by hypersensitivities to normal environmental stimuli such as light, sound, and odor during and, at a lower degree, outside attacks. Understanding of the migraine brain has advanced through neurophysiological and functional imaging studies. Different techniques have emphasized as migraineurs show an increased cortical responsiveness, an altered brainstem processing of peripheral stressors, and an impaired energy metabolism. The involvement of multiple brain networks is not confined to the pain pathway indicating migraine as a complex maladaptive coping state.
