ABSTRACT |
A strong association exists between vertigo and migraine, with migrainous vertigo (MV) being the most common cause of spontaneous (nonpositional) episodic vertigo. Symptoms can be quite variable among patients and within individual patients over time, creating a diagnostic challenge. MV generally presents with attacks of spontaneous or positional vertigo lasting seconds to days with associated migrainous symptoms. Numerous reports have shown that the prevalence of vertigo is higher in patients with migraine than in general population and the prevalence of migraine is also higher in patients with recurrent vertigo of unknown origin than in controls. Although recent studies have increased understanding of the relationship between migraine and vestibular symptoms, the mechanism of migrainous vertigo is still uncertain. A defective ion channel, primarily expressed in the brain and inner ear, may explain headache and vestibular symptoms in patients with migrainous vertigo. Treatment of MV currently parallels that of migraine headache, as proper studies of optimal MV management are just beginning. Controlled studies on the treatment of migraine-associated vertigo are still lacking. |
