Initially, with complaints of dizziness, you need to see a neurologist. Do not be surprised if the doctor starts with "addiction" to elicit from you the details of this phenomenon. The fact is that subjectively the patient may feel that he is dizzy, but in fact it may just be a feeling of faintness or malaise. This kind of "whirling of the head" is called false. The criterion of true dizziness will be the aforementioned sensation of rotation of either your body or surrounding objects. Also, you should tell in detail when and against which these feelings arose. Only in this case the doctor will be able to make a correct diagnosis. Understand that the correct diagnosis can help not to delay with treatment, but immediately go to recovery. Due to this you will less suffer from side effects from the disease. This will have a positive effect on the whole body.
As additional research methods, it may be necessary to perform electroencephalography, ultrasound of the vessels of the neck and head, and, perhaps, more serious methods, such as computed tomography and magnetic resonance imaging.
In our body there is a whole system responsible for the sense of balance. It is called vestibular and includes three anatomical structures: the organ of vision, the actual vestibular apparatus located in the inner ear, and the muscular, or proprioceptive, analyzer. From them, the signal on the nerve fibers, as on telephone wires, enters the "coordination center" - the brain. There, the reverse signal-indication is deciphered and formed, what to do next.
Violation of signal transmission at any of the listed levels can lead to the appearance of a phenomenon of dizziness, or scientifically veritigo. Depending on the exact location of the damage, the symptoms may change. Thus, the defeat of the central zones, that is, the brain, leads to the emergence of a "central type" of dizziness. Then the person will clearly feel the rotation of his body or surrounding objects around him. When nerve fibers or the vestibular apparatus are affected, there are sensations of "sea rolling", this type of dizziness is called peripheral.
With rare exception, dizziness brings a lot of additional unpleasant symptoms. Nausea, vomiting, excessive sweating, dry mouth often accompany the vertigo, these reactions include psycho vegetative disorders. A similar phenomenon arises from the close interrelationship of the two systems - vestibular and vegetative. As a consequence, any defeat of the vestibular system leads to the development of autonomic disorders.
Causes of dizziness are diverse and numerous. Depending on the level of lesion, there are such reasons:
- damage to the brain;
- defeat of the peripheral analyzer (visual or vestibular proper);
- damage to peripheral and central nerve fibers.
