Design: The investigators will perform a study of all children between 6 and 18 years of age who present to the ED with headache or migraine. At the time of the visit providers will be asked to complete a questionnaire regarding exam and history without making any changes to patient care. The investigators will also contact a sub-group of patients who do not undergo MRI or CT, 12-14 weeks after discharge to ask about subsequent headache care after leaving our facility.
