Bárány Society


The International Society for Neuro-Otology



The Bárány Society initiates worldwide evidence based consensus and standardisation regarding definition of syndromes, diseases, diagnostic procedures and treatment by means of its standardisation commitees and discussions with other stakeholders.

To do so, the Bárány Society took the initiative for the establishment of the International Classification of Vestibular Disorders (ICVD) and installed the Classification Committee of the Bárány Society (CCBS). The CCBS formed a number of subcommitees that adress specific vestibular disorders and other associated topics. The guidelines for the subcommitees are agreed upon during the Bárány Society business meeting on May 27th 2014 in Buenos Aires and are as follows:


Composition of the subcommittees:

Every subcommittee will have a chair designated by the Classification Committee of the Bárány Society (CCBS). The chair of a subcommittee should be a member of the Barany Society and report to the CCBS. He/she will compose his/her own subcommittee group according to the following guidelines: at least 3 continents represented, at least one clinician with ENT background and at least one clinician with neurology background. Additional expertise from a different background (like vestibular testing or imaging etc) as needed. The input of each member of a working group should be such that it will qualify for authorship, this should encourage small efficient working groups.



Within 12 months from designation of the coordinator to presentation of first proposal to the CCBS. Internal review process: Each paper undergoes an internal review and consensus process for ICVD Publications in the Journal of Vestibular Research.


1. Subcommittee completes draft document and determines together with the CCBS (Classification Committee of the Bárány Society) that it is ready for input from the Bárány Society membership.


2. The draft document is placed on the JVR website and Bárány Society members are alerted via email or other electronic means that a draft document is ready for comments from Bárány Society members and are directed to a dedicated hidden page.  Only Barany Society members are directed to this page.


3. Comments are provided by interested Bárány Society members via the JVR website. Note that these comments are not visible to the public but only visible to the Editor of JVR.


4. The Editor of JVR forwards all legitimate comments to the relevant subcommittee chair.


5. The subcommittee chairs at their own discretion responds to individual comments by replying to the member who provided the comment, revising the draft document, both, or neither.  The subcommittee chair will involve subcommittee members as they see fit.


6. After some period of time, approximately 3 months, a revised document is prepared by the subcommittee taking into account any comments received from the Bárány Society membership as the subcommittee chairperson and subcommittee members see fit.


7. The subcommittee chair, with the agreement of the subcommittee members and the CCBS, decides whether or not the document is ready for input from colleagues outside the Bárány Society.  If more input is deemed necessary from the Bárány Society membership based on the extent of the revisions, a revised document is placed on the JVR website and another iteration of comments is processed.  If the subcommittee chair and members determine that the document is ready for outside comments, the subcommittee seeks input from relevant societies.


8. After revision based on comments received from societies outside the Bárány Society, a penultimate draft is placed on the JVR website for comment from the Bárány Society membership.


9. As above, relevant comments from Bárány Society members are forwarded to the subcommittee chair by the Editor of JVR and appropriate revisions are made.


10. The subcommittee, with agreement among the subcommittee chair and subcommittee members and the CCBS, advises the Editor of JVR that the document is ready for publication.


11. JVR publishes the document as a special publication available in print and online at both the IOS website and the JVR‐web.org noncommercial website as open access articles. Publication and authorship: The results of the various subcommittees will be submitted for publication to JVR (according to formal decision during the business meeting on May 27th 2014 in Buenos Aires) after the final approval by the CCBS. The members of the subcommittee will be the authors (with the chair as the first author) with the addendum “on behalf of the CCBS” (according to the model of the Symptom classification paper). Dissolution of a subcommittee: After publication of its definition the subcommittee is dissolved. The revision and possible updating of the definition will be done according to the same procedure as described above. All members of the previous subcommittee are eligible for the subcommittee for the revision. Format and content of the definitions: To establish the definitions all available kinds of evidence should be taken into account: clinical description, pathophysiology, vestibular tests, imaging, treatment results, genetics, epidemiology etc. and retain what is essential for the disease definition.


At current the following vestibular disorders and topics are adressed in subcommitees:


vestibular syndromes nomenclature classifications (David Newman Toker)

nystagmus classification (Scott Eggers)

functional and psychiatric aspects (Jeff Staab)

vestibular migraine (Thomas Lempert))

Meniere’s Disease (Antonio Lopez Escamez)

BPPV (Michael von Brevern)

vascular vertigo (Michael Strupp)

acute unilateral vestibulopathy (Mans Magnusson)

presby-vestibulopathy (Yuri Agrawal)

cervical vertigo (Barry Seemungal)

bilateral vestibulopathy (Michael Strupp)

motion sickness and mal de debarquement (Yoon-Hee Cha)

measuring functioning, participation, and quality of Life (Joe Furman, Eva Grill)

laboratory testing (Herman Kingma)

postconcussion vestibular disorders (Michael Hoffer)

superior canal dehiscence (John Carey)


A series of consensus documents is finished or currently under development by the Committee for the Classification of Vestibular Disorders (ICVD) of the Bárány Society. An easy access to these documents is by the following link:





As mentioned above all finilised documents of the CCBS are published open access in the Journal of Vestibular Research.
