Vertigo
Vertigo is a feeling as if the patient moves or rotates, or as if the object moves around the patient or spinning, which is usually accompanied by nausea and loss of balance.Vertigo may last only a few moments or may continue for several hours or even days. Patients often feel better when lying still, but the vertigo can continue even if the patient does not move at all.
Benign paroxysmal Positional Vertigo.
Benign paroxysmal Positional Vertigo is a disease that is often found, where the vertigo occurs suddenly and lasts less than 1 minute. Change the position of the head (usually occurs when patients lie down, get up, rolling over on the bed or turning back) is usually triggered this episode of vertigo. The disease is apparently caused by the existence of calcium deposits in one of the semicircular canal in the inner ear.
This kind of horrible vertigo, but it is harmless and usually disappears by itself within a few weeks or months. Not accompanied by loss of hearing or ringing in the ears.
CAUSE
Body position and control the sense of balance through the balance organs located in the inner ear. This organ has a nerve associated with a specific area in the brain. Vertigo can be caused by abnormalities in the ear, in the nerve connecting the brain and telingan in the brain itself. Vertigo can also be associated with abnormalities of vision or change in blood pressure that occurs suddenly.
Common causes of vertigo:
1. Environmental conditions: Motion sickness (car sick, sea-sickness)
2. Drugs: Alcohol, Gentamicin
3. Circulation disorders: Transient ischemic attack (temporary disruption of brain function due to reduced blood flow to one part of the brain) in the vertebral arteries and arteries basiler
4. Ear disorders: Deposits of calcium in one semicircular canal in the inner ear (cause benign paroxysmal positional vertigo), Inner ear infection because of bacteria, Herpes zoster, Labirintitis (infection of the labyrinth in the ear), Inflammation of the vestibular nerve, Meniere’s disease
5. Neurological disorders: Multiple sclerosis, Skull fracture with injury to the labyrinth, or both innervation, Brain tumors, The tumor is pressing the nerve vestibularis.
SYMPTOMS
Patients feel as if he moves or rotates; or the patient feels as if it moves around or spinning.
Diagnosis
Before starting treatment, must be determined the nature and causes of vertigo. Abnormal eye movements showed abnormalities in the function of the inner ear or the nerves that connect it to the brain. Nistagmus is rapid eye movement from left to right or from top to bottom. The direction of movement can help in diagnosis. Nistagmus can be stimulated by moving the patient’s head suddenly or with cold water dripping into teling.
To test the balance, the patient was asked to stand and then walk in a straight line, beginning with his eyes open, then with eyes closed. Hearing test can often determine the ear abnormalities that affect balance and hearing. Other tests are CT or MRI head, which can show abnormalities of bone or a tumor pressing nerves.
If suspected of an infection, fluid samples can be taken from the ear or sinuses or of the spine. If suspected to have decreased blood flow to the brain, the angiogram examination, to see any blockages in blood vessels leading to the brain.
TREATMENT
Treatment depends on the cause. Medications to reduce mild vertigo that is meklizin, dimenhidrinat, perfenazin and skopolamin. Skopolamin primarily serves to prevent motion sickness, which is in the form of tape with the old skin for a few days work. All of the above drugs can cause drowsiness, especially in old age. In the form of a plaster Skopolamin effect of the least sleep.
Now still developed a new treatment techniques for the SCA, by gene therapy. Genetic therapy is the technique of planting a normal gene into precursor cells (cells that produce blood cells). However, this technique is still in the research phase and only tested on mice. Although the researchers concerned about the difficulty of applying gene therapy in humans, they believe that this new therapy will become an important treatment for sickle cell anemia disease.
