Migraine diagnostic criteria Flashcards
What are the International Headache Society’s diagnostic criteria for migraine without aura?
Criteria for migraine without aura: A) At least 5 attacks; B) Attack duration 4-72 hours; C) Headache characteristics including unilateral location, pulsating quality, moderate/severe intensity, aggravated by physical activity; D) Accompanied by nausea/vomiting, photophobia, or phonophobia; E) Not attributed to another disorder.
What distinguishes migraine with aura from migraine without aura?
Migraine with aura is seen in about 25% of migraine patients and involves symptoms like a progressive aura that may include hemianopic disturbances or a scintillating scotoma, occurring hours before the headache. Sensory symptoms may also occur.
How do the NICE guidelines differ in diagnosing migraine with aura compared to the International Headache Society?
NICE guidelines state that migraine can be unilateral or bilateral and provide details on auras, which should be fully reversible, develop over 5 minutes, and last 5-60 minutes. Atypical symptoms like motor weakness or double vision may prompt further investigation.
