Screening
The three item ID Migraine screen is a validated screening test for migraine in primary care patients presenting for routine care who report having a headache in the last 3 months.[39][79] Nearly all patients (93/100) who answer 'yes' to two out of three questions have migraine:
Has a headache limited your activities for a day or more in the last 3 months?
Do you feel nauseous or are you sick when you have a headache?
Does light bother you when you have a headache?
The Migraine Screen Questionnaire is an alternative tool comprising five questions.[39]
