A diagnosis of migraine headache may be determined if a patient has at least five attacks that meet the following criteria:
- Headache attacks that last four to 72 hours (untreated or unsuccessfully treated)
- Headache that has two of the following characteristics:
- Unilateral site
- Pulsating quality
- Moderate to severe intensity
- Aggravation by walking stairs or similar routine physical activity
- During headache, at least one of the following symptoms:
- Nausea or vomiting (or both)
- Photophobia and phonophobia (unusual sensitivity to light and sound)
- No evidence of another related disease
