Dizziness (vertigo) is a feeling of disrupting the orientation of the body in space. It seems to a person that he or she is rotating or objects that surround him or her. Everyone experiences different impressions from a feeling of intoxication to faintness & instability.

There are more than 80 causes of this disorder. Some of them are combined, so it is not always easy to determine why the head is spinning. Most often the reasons are rather harmless – fatigue, hunger, motion sickness. But in some cases, this can be a sign of a serious illness. Causes of dizziness

Classification

This disorder doctors divided into two large groups:

  • central dizziness – is caused by disorders & diseases of the brain. These can be traumas, tumors, hemorrhages
  • peripheral – occurs as a result of the impact or damage of the inner ear or vestibular nerve.

Also distinguish systemic & non-systemic (physiological):

  • systemic dizziness occurs in the event that one of the systems responsible for orientation in space has failed: visual, vestibular or muscular. This type requires careful diagnosis & comprehensive treatment
  • non-systemic (physiological) can be caused by neurogenic causes – stress, overwork, lack of glucose, low-carbohydrate diets, starvation. Sometimes the reason lies on the surface: the child has long been riding a carousel or a person experiences sickness during a sea voyage. In this case, the cause is the discrepancy between visual images & physical sensations. Such an attack passes by itself & there is no need to conduct a diagnosis of the organism.

To help understand which disease caused the vertigo, additional symptoms & various laboratory methods of investigation may occur.

Types of dizziness in various diseases

In order to correctly determine the cause & to prescribe adequate treatment, it is necessary to know what kind are various diseases & what signs are accompanied. Here are several most common variants:

  1. During the cerebral hemorrhage, the vertigo begins acutely. It is persistent & long-lasting. It is accompanied by doubled vision, severe weakness, speech impairment, muscle sensitivity & poor coordination in space.
  2. Cervical osteochondrosis. Dizziness in cervical osteochondrosis increases with movement, especially with sharp turns & head rises. Also, patients are unstable in gait & disorientation in space, pain & limited movements in the cervical spine.
  3. Injury of head or spine. Also accompanied by nausea & weakness.
  4. Benign positional dizziness. Characterized by increased attack when changing the position of the body in space. There is a special test to confirm this disease.
  5. Basilar migraine. Dizziness begins an hour before the attack & is accompanied by various neurological symptoms, as well as noise in the ears, darkening in the eyes, nausea & vomiting.
  6. Pathology of the eye muscles. The reason is a quick change of pictures. It passes independently in a few minutes.
  7. Reception of antibiotics & other medications. Sometimes vertigo is a side effect of medications: anticonvulsant, sedative, pressure-lowering, cardiac. Also, the drugs Cialis, Viagra & their analogs can cause dizziness. Typically, this is indicated in the instructions. In this case, you need to reduce the dose or stop taking the drug after consulting a doctor.
