Migraine aura status and hyperhomocysteinaemia.

摘要

Migraine with aura (MA) is a common condition; however, MA status is considered very rare. According to the 2004 International Classification of Headache Disorders, MA status is a condition of MA characterized by at least two auras per day for >5 consecutive days (1). Aura status generally resolves spontaneously. However, during the episodes patients are greatly debilitated. It is rare for a MA status to be the first time MA occurs. In fact, patients with MA status have usually had previous attacks of MA. The cause of MA status is unknown. We report two cases of MA status associated with a condition of hyperhomocysteinaemia.
