Vestibular migraine (VM) is vertigo associated with a migraine, either as a symptom of migraine or as a related but neurological disorder, when referred to as a disease unto itself. A 2010 report from the University of British Columbia published in the journal Headache said that "'Migraine associated vertigo' is emerging as a popular diagnosis for patients with recurrent vertigo" but, "in contrast to basilar artery migraine, is neither clinically nor biologically plausible as a migraine variant." Epidemiological studies leave no doubt that there is a strong link between vertigo and migraine.
