The reasoning: pattern first, safety always
Migraine without aura is a recurrent syndrome: at least five attacks lasting 4–72 hours, with at least two of unilateral, pulsating, moderate/severe, or activity-aggravated pain, plus nausea/vomiting or both photophobia and phonophobia. Migraine with aura adds fully reversible visual, sensory, speech/language, motor, brainstem or retinal symptoms that usually evolve gradually and last 5–60 minutes per symptom.
