Dizziness

it seems that things are floating in the same direction, in the third - it appears that his body moves in space. At the same time as there is instability when walking and standing, so sometimes in a sitting position. The above-described vertigo are classified as systemic and are a direct consequence of the defeat of the vestibular apparatus or vestibular nuclei in the brain.
When nonsystem vertigo in a patient the feeling that he is on the deck of the ship, rocking in the waves. Such giddiness is not so painfully tolerated, often appear as though imperceptibly and gradually increase.
occurrence of dizziness shows a certain trouble in the vestibular system is responsible for balance. Therefore, an imbalance in the form of instability when standing, staggering when walking accompanied by tase vertigo. You always have to add the "tase" vertigo, as many patients under vertigo understand anything: and the feeling of heaviness in the head, and "blurred" vision, and suddenly arose a general weakness, and pre-fainting, and feeling light intoxication (not related with alcohol).
vestibular system consists of:
• vestibular system, located adjacent to the organ of hearing;
• vestibular nerve, which is located next to the auditory nerve, and connects the vestibular apparatus in the brain;
• vestibular nuclei in the medulla brain (part of the brain that connects the brain to the spinal) and routes of transmission of momentum from the vestibular nuclei to various areas of the brain responsible for balance and motor coordination (cerebellum), with vision (occipital lobe) for the reception and processing of sensations of body position in space.
vestibular system is very sensitive to any malfunction in the body. She responds to the lack of red blood cells in the blood, which with the help they contain hemoglobin supply all body tissue of oxygen necessary for him (this is possible in acute blood loss or chronic anemia - anemia), and brain injury, and poisoning (alcohol, carbon monoxide , food poisons, etc.).
most often occurs when dizziness of Meniere's disease and circulatory insufficiency in the vertebral arteries supply blood to the vestibular apparatus, vestibular nerve and vestibular nuclei.
Meniere's disease is characterized by sudden, usually against a background of overall health, the development of systemic vertigo (as if the whole room was turned upside down "), accompanied by disequilibrium (often, not only when walking and standing, but also in the sitting position), the feeling of fullness in the ear or noise or hearing loss in one ear, nausea, vomiting, and various autonomic disorders (cold sweats, blanching of the skin, decreased or increased blood pressure). These attacks occur suddenly and suddenly (within minutes or hours) to an end, but tend to repeat: some may be repeated a week later, others - in a year. In some patients after the attack remains a sense of fullness in the ear, the noise in it, and sometimes hearing loss in one ear. The development of Meniere's disease is associated with impaired circulation of the endolymph in the semicircular canal of the labyrinth.
muchmorelikely to occur when vertigo of circulatory failure in the vertebral arteries. The reason for this may be and atherosclerosis, which leads to a narrowing of the vascular lumen, and a violation of the vascular tone (that is, in some cases increasing and in others - lowering blood pressure), and compression of the vertebral artery at the site of its passage in the bone canal of the cervical spine osteophytes ( bony outgrowth). With the development of acute circulatory failure in the vertebral arteries vertigo comes on suddenly and may resemble the pattern of disease observed in menerovskom attack, although as a asle, it is less pronounced, but the attack ismoredurable. In chronic circulatory failure in the vertebral artery dizziness often is non-systemic in nature, less pronounced, accompanied by a staggering when walking (I was on the street make for a dasnk "- complaining about such patients).
Dizziness can occur in a complex of symptoms that characterize the vegetative crises (abroad often use the term "panic attack"). In addition to dizziness, with vegetative crises arise heartbeat, numbness or cooling hands and feet, lack of air, oznobopodobnoe jitter, which is usually accompanied by a feeling of fear (panic). Such conditions have been reported in patients with vegetative-vascular dystonia, depression, or neurosis.
causes of vertigo may be inflammatory (primarily in the middle and inner ear), and tumors in areas where there are certain sections of the vestibular system. That's why should not engage in self, and be sure even if not strong vertigo refer to a neurologist and undergo a full examination.
But particularly frightened, you should not, since the majority of patients suffering from vertigo, a so-called benign positional vertigo that occurs when moving the head or a change in head position (eg, by turning his back on his side) and lasting for a few seconds . Of course, only a detailed neurological and otonevrologicheskoe (and where not otonevrologa - ENT) examination will determine whether there is a benign positional vertigo or dizziness when turning his head due to serious illness.
vertigo non-system, combined with a sense of blackout and the instability that occurs during the transition from horizontal to vertical, it is noted for orthostatic hypotension when there is a decrease in systolic (upper) blood pressure by 20 mmHg. Art. and more, and usually at the same time is reduced and diastolic (lower) pressure. The sharp reduction in pressure is usually offset by increased frequency of cardiac rhythm. Orthostatic hypotension is possible with diabetic polyneuropathy and other endocrine disorders, prolonged and often uncontrolled taking psychotropic dasgs and money, lowers blood pressure, the syndrome of Shy - Dreydzhera in which blood pressure can drop from 160/90 mm Hg. Art. Lying to 60/20-40/0 mm Hg. Art. standing (with increased frequency of heart rate does not occur, there are often faint). The diagnosis of orthostatic hypotension may put the patient himself, by measuring the pressure in the supine and standing, which of course does not relieve him from seeking medical attention.
Treatment of vertigo - is primarily a disease treatment that caused them. In cases where there is no definitive therapy, such as, for example, Meniere's disease, help dasgs that reduce the excitability of the vestibular system and prevent attacks. Among these means occupies an important place betahistine. In combination with cardiovascular dasgs it is effective not only for Meniere's disease, but also for circulatory failure in the vertebral arteries. However, it should be taken only after consulting your doctor.
patients with chronic vertigo, should be particularly scaspulous respect the work and rest, to spendmoretime outdoors, normalize sleep and meals (to limit salt, fat, spicy, high-calorie foods, alcohol, coffee, and eatmorefasits, fresh vegetables , low-fat dairy products). Developed special facilities vestibular exercises, holding that it is desirable to begin under the guidance of an experienced practitioner.
