Migraine and ischaemic vascular events.
An association between migraine and ischaemic vascular events, particularly ischaemic stroke, has been debated for many years. The pathophysiology of migraine has been explored in detail, and it is known that a dysfunction of brain cells and arteries is a major component of this disorder. The involvement of cerebral arteries during the migraine attack as well as the high prevalence of migraine among young individuals with ischaemic stroke has led to the hypothesis that migraine may be a risk factor for ischaemic stroke. Furthermore, there is evidence that the vascular nature of migraine is not limited to meningeal blood vessels and that migraine and overall cardiovascular disease may share aetiological pathways. The aim of this review is to summarize the epidemiological evidence that links migraine with ischaemic stroke and ischaemic heart disease and to discuss potential biological mechanisms.
