Recommendations
Suspect migraine without aura in a person with recurrent moderate to severe headache, particularly if pain is unilateral and/or pulsating, and when the person has accompanying symptoms such as photophobia, phonophobia, nausea and/or vomiting.
Suspect migraine with aura in a person with the symptoms above and recurrent, short-lasting visual and/or hemisensory disturbances.
Suspect chronic migraine in a person with ≥15 headache days per month.
Suspicion of migraine should be strengthened by a family history of migraine and if onset of symptoms is at or around puberty.
