What is dizziness?

Vertigo – so called true vertigo. This is a state where a person has a feeling that objects around him (or the whole world) rotate, or there is a feeling that he himself is spinning or moving, while standing still. To understand this, remember the feeling that you have, if you spin for a long time or ride on the carousel.

True vertigo is always a serious illness or damage to the nervous system or the vestibular system adjacent to it. The vestibular apparatus (it is located deep in the ear) is responsible for the position of the body in space, the control of posture, the stability of the person and the coordination of his movements.

However, coordinate the position of the body in the space of the eye and skin-muscle reflexes, and controls all sensations and actions – the brain. The receptors of responsible, coordinating, body-controlling systems are located in all parts of the body, from bones and muscles to internal organs. That is why, when a person is dizzy, he becomes sick.

The good news is that in the vast majority of cases, dizziness is not a symptom of a serious illness. Such attacks of vertigo arise spontaneously and just as spontaneously pass, they usually occur when sharp turns of the head or body in different directions.

The reason for this phenomenon is a sharp and unusual irritation of the nerves inside the vestibular apparatus with special substances. This usually happens after 50 years. The attack occurs when the head tilts back, turns in bed, sharp bends. At the same time can be sick. The attack lasts up to a couple of minutes and passes by itself. The basis of treatment is a set of special exercises, which trains the vestibular apparatus.

Psychogenic

Such attacks occur in overly emotional and impressionable people with phobias, and in this case there are no true disorders in the vestibular apparatus. At the same time, people describe dizziness as confusion, fog in the head, fear of falling and injuries, and circling of objects and bodies.
