AbstractVertigo consists of a variety of syndromes and can be due to many etiologies. One of these causes is migraine, which in our experience is often overlooked, although migrainous vertigo is well known in the literature. Vertigo in migraine can occur as aura or during the headache phase, or independent of the attacks as aura without headache. The aim of this retrospective study was to analyze cases with vertigo and migraine: 23 (8%) of 298 patients with migraine examined in a neurological outpatient department also had rotational vertigo. 48% of these patients had vertigo independent from typical migraine headache. Two types of vertigo were found: permanent vertigo, and vertigo with the characteristics of paroxysmal positional vertigo. 57% of the vertiginous attacks lasted hours, 26% even days, and 17% minutes. Most of the patients had several attacks of vertigo, some involving up to 30 episodes. To recognize migraine as a cause of vertigo has therapeutic implications. Most of our patients with vertigo and migraine showed a good response to antimigraine therapy.
