Abstract：Over the last 30 years,research on behavioral factors affecting spatial orientation and balance function has made great progress.Functional and psychiatric vertigo are very common and probably more common than structur-al vertigo.A classification system is in preparation for this emerging clinical problem category.In the ICD-11 beta draft and the International Classification of Vestibular Disorders,PPPD will have its proper definition and diagnostic criteria.Functional vertigo is different from psychiatric vertigo,although psychiatric disorders can adversely affect prognosis for patients with structural vestibular diseases.Structural,functional and psychiatric conditions indeed overlap and this will alter the dichotomous thinking in medical diagnostics of vertigo.Fortunately,pharmacologic,psychotherapeutic,and re-habilitative treatments of functional vertigo have improved in recent years.Dynamic posturography and fMRI will play crucial roles to demonstrate the underlying mechanism in the future.Diagnostic and therapeutic approaches are necessar-ily multidisciplinary and likely managed by neurologists and otologists,whom patients usually consult first.
