Migraine affects an estimated 12% of the population. Global estimates are higher. Chronic migraine (CM) affects 1% to 2% of the global population. ⋯ Migraine is associated with cardiovascular disease, psychiatric disease, and sleep disorders. It is the second most disabling condition worldwide. CM is associated with higher headache-related disability/impact, medical and psychiatric comorbidities, health care resource use, direct and indirect costs, lower socioeconomic status, and health-related quality of life.

Diagnostic testing is of limited value among patients with migraine who present to an emergency department. Various nonopioid, disease-specific treatments are available for patients who present to an emergency department with migraine headache and associated features. Emergency physicians should recognize that the acute migraine presentation is part of an underlying disorder; care should be geared to the underlying headache disorder in addition to the acute attack.
