Are migraineurs naturally born "well-hearted"?

Migraine is a common episodic brain disorder characterized by recurrent attacks of disabling headache.(1) In one-third of patients, headache is preceded or accompanied by aura symptoms, which are transient and fully reversible hemispheric neurologic symptoms. In the absence of any objective marker, the diagnosis of migraine is clinical and based on the criteria proposed by the International Headache Society, which distinguish migraine without aura (patients who have never had an aura) and migraine with aura (patients who have had at least 2 auras, irrespective of the number of attacks without aura they have had).(1).
