Migraine is a chronic neurovascular disorder characterized by severe recurrent headaches. It is one of the most common and most prevalent disabling neurological conditions, characterized by episodes often called migraine attacks. They are quite different from regular headaches which are non-migrainous. Migraineurs generally have a lower threshold to triggers that might cause neuronal hyperexcitability, including sleep disturbances, environmental or emotional challenges, alcohol exposure, diet, and hormonal cycles/changes, among others. Migraine attacks can cause significant pain for hours to days and can be so severe that the pain is disabling. Migraine headache is typically throbbing, unilateral (one sided), and is aggravated by physical activity. It typically presents with additional symptoms in addition to headache pain, including nausea, and sensitivity to light and/or sound.
