Definition of vertigo:
The VERDI study will adopt the nomenclature of the Bárány society, the leading international organization for clinicians and researchers involved in vestibular medicine. The Bárány society previously realized the International Classification of Vestibular Disorders (ICVD), a uniform way to describe vestibular symptoms. The VERDI study will focus on patients with vertigo (defined by the ICVD as the sensation of self-motion when no self-motion is occurring or the sensation of distorted self-motion during an otherwise normal head movement”) and/or episodic vestibular syndrome (defined by the ICVD as clinical syndrome of transient vertigo, dizziness, or unsteadiness lasting seconds to hours, occasionally days, and generally including features suggestive of temporary, short-lived vestibular system dysfunction”). When assessing a patient with vestibular symptoms, the Bárány society recommends focusing on timing (onset, duration, and evolution of symptom) and triggers (actions, movements, or situations that provoke the onset of symptoms. During the diagnostic accuracy study, the researchers will investigate the diagnostic value of timing, triggers, and other (individual and combinations of) items of history taking.
