What is vertigo?
Vertigo is a type of dizziness or a sensation of movement when none is actually occurring. The precise definition of vertigo is an illusion of motion. But in common parlance, it refers not just to illusions of motions but chronic or intermittent
sensation of loss of balance.
Vertigo is a sensation of moving or spinning within stable surroundings, and it may be accompanied by loss of balance and nausea. Vertigo may last for a few moments, several hours, or even days. The person experiencing vertigo often describes the sensation as whirling or spinning. Vertigo is most common in elderly people, but can affect both sexes at any age. Vertigo usually occurs as a result of a disorder in the vestibular system (i.e., structures of the inner ear, the vestibular nerve, brainstem, and cerebellum). The vestibular system is responsible for integrating sensory stimuli and movement and for keeping objects in visual focus as the body moves.
Vertigo is a symptom, not a disease. Vertigo is what some people have just after they ride on a carousel. They briefly feel as though they are still moving, even after they have both feet planted firmly on the ground. People with vertigo may feel that they are moving or that the surroundings are moving while they remain still. Vertigo usually occurs when a person is standing. But it sometimes occurs while a person is sitting, lying down, or changing position. People with vertigo may also have nausea, sometimes with vomiting, and abnormal jerky eye movements (nystagmus).
