Vertigo is a sensation of spinning. When a sufferer of vertigo is tested in real time, the observer can see a typical movement of his eyes. In the medical nomenclature it is called nystagmus.
The nystagmus can be horizontal, vertical or rotatory. The patient can report of the direction of his movement in terms of: "the head is moving", "the room is moving". It is possible to hear a more detailed report such as: ""the room is moving from right to left", or "the head is in a vertical movement". The attacks of vertigo last minutes to hours, but may remain even more than one day.
Between the attacks the patient may remain steady, or report of unsteadiness, imbalance or dizziness. Attack of vertigo or sensations of dizziness unsteadiness or imbalance may precede the full clinical picture of Meniere's disease.
Motion sickness is a term for series of symptoms that are attributed to the vestibular system (including the CNS) and may occur in humans who experience motion or simulation of motion under various conditions.
The pathophysiological mechanism is thought to be the existence of a contradictory messages presented to the cortex of the central nervous system from two sources: (1) visual perception of motion. (2) vestibular system perception of motion.
The circumstances of the occurrence are associated with the terminology of the type of the sickness. Seasickness is considered the well known type, car sickness is a less known, travel sickness is the third, and was notable when the air crafts were smaller, simulation sickness, airsickness or space sickness are the six common ways to classify it.
On the contrary, similar symptoms may occur in a series of medical conditions such as vertigo, dizziness or meniere's disease without any apparent provoking stimuli of the eyes and the vestibular system of the inner ear.
The sufferer of the motion sickness (who, in Yiddish, is shouting Gevald!) is usually complaining of vertigo, dizziness and nausea.mMany of them are vomiting as a result of their nausea. When the sufferer feels fatigue or tiredness together with the motion sickness, the diagnosis of sopite syndrome is done. Sea Sickness is a form of motion sickness that became the most famous.
