[Modern diagnostics of vestibular dysfunction].
Based on the data of anatomy and physiology of vestibular apparatus, authors reviewed methods of assessment of its functional state, theoretical and practical aspects of their strength and limitations. A special attention is drawn to current approaches to investigation of vestibular-ocular reflex (VOR) in different pathologies. The authors emphasized that the diagnostics of vestibular dysfunction should be based on a battery of tests. Both traditional and new methodologies should be used.
