Migraine aura without headache: benign, but a diagnosis of exclusion.

Migraine aura without headache should be considered as a diagnosis in anyone who has recurrent episodes of transient symptoms, especially those that are visual or neurological or involve vertigo. Visual and neurological symptoms due to migraine are not unusual and most commonly occur in older persons with a history of migraine headaches. Migraine aura without headache should be diagnosed only when transient ischemic attack and seizure disorders have been excluded.
