It has been estimated that 10% of patients that present at an emergency clinic have vestibular disorders, including vertigo, and these disorders are frequently a cause of falls in elderly patients. On the other hand, many physicians treat their patients with vertigo with vestibular blockers, which treat the symptoms but do not cure the disorders. We feel that it is important to supply a source of information on the vestibular system and balance disorders, and this title will do that in a comprehensive manner. This title will be an ideal reference for the diagnosis and treatment of vestibular disorders for otolaryngologists, neurologists, neuro-ophtalmologists, audiologists and physical therapists.
