Proposed phases of a migraine attack

Migraine attacks can be broken down into four phases: premonitory, aura, headache, and postdrome, as shown on the slide.^{[Dodick, 2018; IHS, 2018]} The exact timing of each phase is highly variable; the headache phase of a migraine can range from 4–72 hours in adults, and 2–48 hours in children.^{[Dodick, 2018]} However, in most people, the median time to peak intensity of the headache pain is 1 hour, and the median duration of the pain is 24 hours.^{[Dodick, 2018]}
