Vertigo and dizziness related to migraine: A diagnostic challenge

Abstract

Vertigo and dizziness can be related to migraine in various ways: causally, statistically or, quite frequently, just by chance. Migrainous vertigo (MV) is a vestibular syndrome caused by migraine and presents with attacks of spontaneous or positional vertigo lasting seconds to days and migrainous symptoms during the attack. MV is the most common cause of spontaneous recurrent vertigo and is presently not included in the International Headache Society classification of migraine. Benign paroxysmal positional vertigo (BPPV) and Ménière's disease (MD) are statistically related to migraine, but the possible pathogenetic links have not been established. Moreover, migraineurs suffer from motion sickness more often than controls. Persistent cerebellar symptoms may develop in the course of familial hemiplegic migraine. Dizziness may also be due to orthostatic hypotension, anxiety disorders or major depression which all have an increased prevalence in patients with migraine.
