Patients with migrainous infarction (replaces complicated migraine) have previously fulfilled the criteria for migraine with aura. Their present attack is typical of previous attacks, but neurologic deficits are not completely reversible within 7 days, and/or neuroimaging demonstrates ischemic infarction in the relevant area. Other causes of infarction are ruled out by appropriate investigations.
