A detailed headache history is necessary to establish the diagnosis of migraine variants. As many as 20% of patients with migraine variant may experience prodromal symptoms without subsequent headaches. Such paroxysmal symptoms, with the recurrent attacks of transient neurologic symptoms, with or without headache, with a positive family history of migraine, and with a normal neurologic examination interictally, are confirmatory.
