- In case of vertigo, people have the illusion that the environment (walls, floors, ceilings, objects) starts to move or to move themselves in space (1).
- These manifestations are related to a balance disorder (1).
- The duration and frequency of dizziness vary greatly (1).
- Vertiginous sensations are close to vertigo and can also be linked to a balance disorder. Vertiginous sensations usually disappear as soon as the person takes support somewhere, sits or lies down (1).
- Vertigo can be accompanied by various symptoms: nausea or vomiting, sweating, hearing loss, tinnitus, headache (1).
- Due to an increase in pressure in the auditory labyrinth, of unknown origin, Ménière’s disease is at the origin of intense and rotational vertigo attacks, which last about twenty minutes or even a few hours (1).
- These dizzying seizures are accompanied by severe nausea and vomiting, tinnitus and hearing loss (1).
- The disease progresses to chronic lesions in the labyrinth responsible for chronic dizziness, permanent balance disorders and progressive deafness (1).
