Diagnostic Criteria for MdDS were published by the Bárány Society in 2020. The International Classification of Vestibular Disorders (ICVD) evidence-based consensus document can be found at.
Primarily diagnosed by an otolaryngologist or neurologist using patient history (e.g., recent travel or other motion experience) and by exclusion of other disorders, an MdDS diagnosis is usually not given unless a patient has experienced symptoms persisting for at least one month.
Presently there are no tests that can provide a definitive diagnosis of MdDS. Your doctor may order tests to eliminate other disorders which may have similar symptoms. A partial list of tests can be found on the Getting Diagnosed page of this website.
