Simple and efficient recognition of migraine with 3-question headache screen.

ABSTRACT

OBJECTIVE: To correlate the results of a new 3-question headache screen to 3 established methods of diagnosing migraine the International Headache Society diagnostic criteria, physician's clinical impression, and presence of recurring disabling headaches. BACKGROUND: A simple tool to recognize patients who experience migraine may facilitate diagnosis of this debilitating and frequently undiagnosed condition. METHODS: Primary care physicians and neurologists in the United States enrolled 3014 adults with a diagnosis of migraine based on one of the following International Headache Society criteria, an investigator's clinical impression, or presence of recurring disabling headaches. Each patient completed a 3-question headache screen (1) Do you have recurrent headaches that interfere with work, family, or social functions? (2) Do your headaches last at least 4 hours? (3) Have you had new or different headaches in the past 6 months? A diagnosis of migraine was suggested by a yes answer to questions 1 and 2 and a no answer to question 3. RESULTS: The 3-question headache screen identified migraine in 77% of the study population; including 78% of the patients enrolled based on International Headache Society criteria, 74% based on clinical impression, and 68% because of recurring disabling headaches. CONCLUSIONS: Positive 3-question headache screen results agreed well with migraine diagnoses based on International Headache Society criteria, clinical impressions, and presence of recurring disabling headaches. These findings support use of the 3-question headache screen to recognize migraine.
