Abstract
Persistent aura symptoms in patients with migraine are rare but well documented. The International Headache Society defines persistent aura without infarction as when the aura symptoms persist for >1 week without radiographic evidence of infarction. The visual aura of migraine attacks has been explained by cortical spreading depression. We describe a case of a 28-year-old Mexican woman, who presented with persistent aura symptoms, and a literature review. The patient had a 24-year history of migraine headache. In November 2005 the patient had an attack which started with scintillating scotomas bilaterally associated with photopsias and amaurosis followed by migraine headache. All imaging studies were negative. The episode lasted 35 days and probably resolved with nimodipine therapy. Persistent aura symptoms are rare entities. This is the first case documented of a Mexican patient with persistent aura without infarction and probably resolved with nimodipine therapy.
