What causes dizziness?
When someone says that he has dizziness or vertigo, it is a disturbance of orientation in space. It manifests itself with the feeling that your head is constantly moving as if you were in a carousel. Illusions of movement in space also occur. These are mainly the descriptions given by those who suffer from vertigo. There is also a functional peripomotor disorder, which means a disorder of the walking condition, ie patients have a feeling of swinging and this whole condition causes nausea.
Reason for occurrence
It should be noted that dizziness or vertigo is not a disease. It is also a condition that can occur for a number of reasons. Among the most common causes of its occurrence are: inflammation of the vestibular nerve, changes in the tissue of the cervical spine, Meniere’s disease, disorders of blood flow to the brain, excessive muscle tension, various injuries, tumor of the auditory nerve, stress dizziness, tension etc.
People who suffer from vertigo most often describe this condition as a disturbance in the balance of motion in two ways, as a movement caused around the head or in it, or as a loss of orientation in space. These difficulties increase with each movement of the head as well as with each change in body position, and hearing loss, tinnitus, and nausea are also very common. Specific phenomena in the vertigo are the feeling of movement of objects, ie the feeling as if the object you want to reach escapes you, the feeling of movement of your own body in space, the feeling of losing in space, falling and carried to the side or forward – backward.
The most common types of dizziness
Otogenic vertigo, or dizziness caused by diseases of the inner ear, is manifested in such a way that the objects we see move horizontally from the diseased to the healthy ear, and the balance is extremely disturbed in the diseased ear.
False vertigo is characterized by the appearance of dark or shining stars suddenly in front of the eyes, often accompanied by fainting, strange pressure in the head or ears. The most common cause of this type of dizziness is short-term deficiency or reduced blood flow to the brain or neck.
Postural vertigo is the most common vertigo that occurs in 1 in 10 people. This type of dizziness is caused by inadequate movement or position of the head, and all this in a state of lying or moving the head backwards. This condition does not last more than 1 minute, and is accompanied by muffled hearing, rhythmic trembling of the eyes and can recur over a period of several days, or after several months.
Inflammation of the vestibular nerve is manifested so that this type of dizziness can last up to several days and then gradually disappear. Most doctors believe that this phenomenon is caused by inflammation of the vestibular nerve of the inner ear, although there is no scientific evidence for this claim.
Meniere’s disease. This is a microcirculation disorder in the inner ear. This disease is characterized by attacks of dizziness that last from several minutes to several hours. Also this attack of dizziness can be quite strong so that the person will not be able to stay on their feet for long. This condition is also accompanied by tinnitus, nausea, vomiting, loss of balance and the like.
Tumor of the auditory nerve. This condition is characterized by constant dizziness. This condition is also accompanied by hearing loss and impaired function of other nerves in the brain.
