Migrainous vertigo is accepted as a common cause of episodic vertigo, affecting about 1% of the population 1. A recent survey comparing the occurrence of vestibular complaints in 327 migraine patients and 324 controls without frequent headache reported dizziness or vertigo in 52% of migraine patients versus 32% of controls (P<0.0001) 2. Furthermore, 23% of those migraine patients with vestibular complaints met criteria for the diagnosis of migrainous vertigo. Patients with migraine with aura had significantly more migraine attacks associated with vestibular complaints always (15% vs. 10%) or sometimes (22% vs. 5%) (P<0.0001). Vestibular abnormalities have been identified in migraineurs when asymptomatic between headache episodes.
