Causes and mechanisms of dizziness in cervical osteochondrosis, various types of dizziness, as well as diagnosis and treatment.
Dizziness is one of the most common symptoms of a disorder of the vestibular apparatus associated with cervical osteochondrosis.
Causes and mechanisms of dizziness in cervical osteochondrosis
The cause of vestibular disorders, including dizziness, is the combined effect of three components - the vascular, muscular and articular sensation, as well as the pain factor with the prevalence of some of them.
For example, a violation of movement in the joints of the cervical spine causes the appearance of pathological nerve impulses (absent in normal), going to the vestibular apparatus and the cerebellum.
On the other hand, these organs on the affected side are not sufficiently enriched with oxygen and nutrients due to impaired blood circulation.
All this promotes a subjective feeling of dizziness, which is even more so, the more pronounced described changes.
Another possible mechanism for the development of dizziness in cervical osteochondrosis is the direct effect of one-sided lesion of the cervical nerve plexus on the nuclei of the vestibular apparatus from the corresponding side.
There are other possible mechanisms of development of dizziness, the implementation of which depends on the features of the structure of the cervical spine, blood supply to the brain (and in particular the vestibular apparatus) and other reasons.
Types of dizziness
There are three types of germs:
- Systemic dizziness, which manifests itself as a sense of rotation of surrounding objects or of the body, sometimes describes feelings as "rotation within the head";
- Dizziness, manifested in the form of instability and stinging, is sometimes described as a feeling of failure;
- Combined dizziness combining signs of both types.
Depending on the mechanism that caused dizziness in cervical osteochondrosis, different variants of the clinical picture are possible.
Reflex angiospastic formosteochondrosis
Symptoms are caused by reflex spasm of the vessels of the cervical spine. The type of dizziness is systemic or combined.
Dizziness is often accompanied by a change in the color of the face of the face, increased sweating, nausea or vomiting, noise in the ears (high tone), sometimes there is a forewarness.
Dizziness attacks occur several times a week, and usually last no more than 10 minutes.
Compression and irritative form of osteochondrosis
Symptoms of dizziness are due to mechanical disturbances of blood circulation on the vertebral artery. Characterized by a non-systemic and mixed type of dizziness, greatly enhanced at cornering of the head.
Often dizziness is accompanied by noise in the ears, pain in the ear on the side of the lesion, as well as hearing loss.
Approximately a quarter of people who suffer from this form of cervical osteochondrosis, there is an appearance of attacks of dizziness and nausea when looking at moving objects.
The clinical picture of cervical osteochondrosis is extremely diverse, and a large number of possible variants for the development of disorders in the work of the vestibular apparatus does not allow the qualitative use of such an important symptom for the diagnosis of diseases.
To clarify the causes of dizziness, including cervical osteochondrosis, the following methods are used:
- Collecting information about subjective feelings of a person;
- Definition of neurological status;
- X-ray examination methods (with the contrast of neck vessels);
- Ultrasound dopplerography;
- Magnetic resonance imaging (allows you to determine the state of the problem areas of the brain).
To relieve the symptoms of dizziness should be clarified their nature and start the therapy of the underlying disease. It is possible to use sedative and other means after consultation with a neurologist.
