Migraine symptoms asked of those reporting headache once or more per month, included photophobia, nausea, unilateral location, visual disturbance during / just before headache, unilateral numbness during / just before headache

Subjects are classified according to headache symptoms into four mutually exclusive categories:
No headache Does not have headache once or more per month
Non-migraine headache Headaches with no more than one associated symptom
Migraine without aura (MO) Headaches with two or three of photophobia, nausea, unilateral location
Migraine with aura (MA) Headaches with visual and/or sensory aura

Those with aura and non-aura symptoms are included in the aura category.
