RESUMO
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.
La pathologie vertigineuse peut être séparée en deux grandes entités. Le vertige vrai, sensation rotatoire, «vertigo¼ des auteurs anglo-saxons et l'instabilité, «dizziness¼ des mêmes auteurs. L'anamnèse est la clé du diagnostic, précisée par des explorations fonctionnelles. En pratique, 10 % des patients vertigineux sont référés aux médecins spécialistes. Une mauvaise explication de la pathologie au patient peut entraîner des troubles fonctionnels importants qui peuvent évoluer en troubles psychologiques.
