Vertigo is a type of dizziness often described as the feeling that the body or surrounding environment is spinning or tilting, even though both are actually stationary. People with migraine frequently report experiencing episodes of dizziness and vertigo, so experts have long suspected that there is a connection between them. Recent research in this area has provided enough evidence for the proposal of a new possible category – vestibular migraine – to describe vertigo that may actually be caused by migraine. This phenomenon was formerly known as "migraine-associated vertigo/dizziness" or "migrainous vertigo."

The International Headache Society, working together with the Bárány Society for vestibular research, has included vestibular migraine in the 2013 version of The International Classification of Headache Disorders, 3rd Edition (ICHD-III). It is important to note that vestibular migraine is not currently recognized by the ICHD-III as an actual migraine type, but rather an "episodic syndrome that may be associated with migraine." Vestibular migraine is listed in the appendix of the ICHD-III, which means that researchers will continue to investigate it over the next few years. If enough evidence is gathered, then it may be included as an official migraine classification in the next edition of the guidelines.
