The present work forms part of an ongoing multi-year project to develop an ICVD, which uses a structured process for developing international consensus definitions for vestibular symptoms, syndromes, disorders, and diseases. This process, overseen by the Classification Committee of the Bárány Society (CCBS), is based on expert, multi-disciplinary committees with international representation developing diagnostic criteria for subsequent comment and refinement prior to publication. These criteria are built on a critical appraisal of current best scientific evidence. All definitions are supported by notes, comments, and written discussion according to a template established by the CCBS for ICVD. The criteria for BVP were developed iteratively over a three-year period (2014–2017) through discussion, presentation, and refinement. Special care was taken to ensure that the criteria are specific and practical and can be applied in every country all over the world. This is particularly true for the use of certain laboratory examinations not available everywhere.
