Origin of vertigo due to disturbances in the body's balance system. Balance system of our body is divided into 2 vestibular system (central and peripheral) and non-vestibular (visual, and somatokinetik).
Vertigo can be caused by, among other things:
- Alcohol Lonsumsi
- Drugs such as streptomycin, quinine, salicylates, carbamazepine, indomethacin, aminoglycoside, etc.
- Migraine attacks
- Arthritis in the neck
- Bacterial infections of the ear
- Viral infections such as the flu that attacks the maze area
- Lack of oxygen to the brain.
- Abnormalities of vision
- Changes in blood pressure that occurs suddenly
- Disruption in the nerve that connects the ear to the brain
- Middle ear disorders and in
Pathophysiology of vertigoVertigo occurs if the afferent information conveyed to the center of consciousness is not appropriate. Composition of Afferent the most important in this system is the arrangement of vestibular or balance, which is continuously deliver impulses to the center of balance. Another arrangement is the role of optical systems and pro-prioseptik, which connects the vestibular nuclei with the nuclei N. III, IV and VI, the structure vestibuloretikularis and vestibulospinalis.
Useful information for the balance of the body would be arrested by the vestibular receptors, visual, and proprioseptik, vestibular receptors contribute the most, ie more than 50% followed the visual receptors and the smallest contribution is proprioseptik.
Under normal conditions, the information arrives at the center of integration tools from the balance receptors vestibular, visual and proprioseptik left and right will be compared, if everything is in a state of synchronous and reasonable, will be processed further. The response appears in the form of adjustment of the eye muscles, and drive the body in motion. In addition, people are aware of the position of the head and body to the surrounding environment. If the function of the tool body balance in the peripheral or central in abnormal condition, or there is excessive movement stimuli, the processing of information would be disturbed, resulting in symptoms of vertigo. In addition, the response of muscle to be not appropriate adjustments so that they appear to be abnormal movements nystagmus, unsteadiness, and other symptoms.
Vertigo symptoms such as:
- Dizziness was the most common complaint
- Head feels light
- Sense of floating or swinging
- Feeling as if he was moving or spinning or feeling as if the object moves or rotates around
- Nausea, sometimes vomiting
- Cold sweat
- Swaying while standing or walking
- Unable to focus the view
Classification of VertigoBased on the cause is divided into:
- Epileptica Vertigo is dizziness that accompanies or occurs after seizure
- Laryngea vertigo dizziness because of coughing
- Vertigo nocturna are feeling as if it would fall at the beginning of sleep
- Ocularis vertigo dizziness because of eye disease in particular because of paralysis or muscle activity imbalance eyeball
- Rotatoria vertigo dizziness as if all around the body swirling.
Based on the duration of the attack can be divided into:
- Vertigo Acute: sudden attack, the intensity slowly decreased but the patient had never experienced a period of perfect free of complaints
- Paroxysmal vertigo: occurs suddenly, lasts a few minutes or days, and then disappeared perfect. One time the attack may appear again. However, between attacks, the patient did not feel any symptoms
- Vertigo cronies: attack long settled and constant intensity.
Based on the nature of the vertigo symptoms or differentiate into:
- Vestibular vertigo, spun and triggered by head movement.
- Peripheral: vertigonya weight and degree of hearing loss may be accompanied by deafness or ringing in the ears
- Central: vertigo degrees milder and usually not accompanied by hearing loss.
- Non-vestibular vertigo, was floating or loss of balance and instigated by the movement of an object in the visual
