Status migrainosus



Status migrainosus is defined as an attack of severe migraine lasting more than 72 hours accompanied by debilitating symptoms and is not attributable to another disorder. For patients presenting with the first or worst prolonged headache, a thorough neurologic evaluation with collateral imaging or spinal fluid sampling is indicated to assess for secondary causes of pain. In a patient with diagnosis of migraine without a secondary attributable cause of prolonged headaches, focus should be on swift and effective treatment with the primary aim of aborting the migraine.
