Abstract

Symptoms of vertigo and dizziness may arise from a dysfunction of the vestibular system in the inner ear but many or even most of them don't. The medical interrogatory is a key step for the diagnosis, combined with functional tests. Around 10 % of patients with vertigo are referred to specialists. They are a lot of psychogenic dizzy symptoms. The importance of a reassuring dialogue with the patient is of prime importance to avoid the development of functional or psychological imbalance.
