The headache may be accompanied by a variety of multiple organ system symptoms, such as allodynia, nausea, vomiting, and urinary frequency. There are various types of migraine, the diagnostic criteria for which are established by the International Headache Society.4 The types of migraine are divided into two groups: migraine without aura (“common migraine”) and migraine with aura (“classic migraine”). Further subdivisions include migraine with typical aura with or without headache, familial hemiplegic migraine, sporadic hemiplegic migraine, basilar type migraine, and retinal migraine.4
