A balance disorder is a disturbance that causes an individual to feel unsteady, giddy, woozy, or have a sensation of movement, spinning, or floating.
By the way, an organ in our inner ear, the labyrinth, is an important part of our vestibular system. Basically the labyrinth interacts with other systems in the body, similar to the visual and skeletal systems, to maintain the body’s position. These systems, together with the brain and the nervous system, can be the source of balance problems. Three the labyrinth structures, the semicircular canals, we shall know when we are in a rotary motion. Semicircular canals, the superior, posterior, and horizontal, are fluid filled. With all that said… Motion of the fluid tells us if we are moving. Essentially, the semicircular canals and the visual and skeletal systems have specific functions that determine an individual’s orientation. Besides, the vestibule is the region of the inner ear where the semicircular canals converge, close to the cochlea. On p of this, the vestibular system works with the visual system to keep objects in focus when the head is moving. Furthermore, joint and muscle receptors also are important in maintaining balance.
Basically the brain receives, interprets, and processes the information from these systems that control our balance.
Whether we are nodding our head up and down or looking from right to left, movement of fluid in the semicircular canals signals the brain about the direction and speed of rotation of the head as an example.
Any semicircular canal has a bulbed end, or enlarged portion, that contains hair cells. Rotation of the head causes a flow of fluid, that in turn causes displacement of the p portion of the hair cells that are embedded in the jellylike cupula. You should take it into account. Two other organs that are part of the vestibular system are the utricle and saccule. Then again, we are talking about called the otolithic organs and are responsible for detecting linear acceleration, or movement in a straight line. Basically the hair cells of the otolithic organs are blanketed with a jellylike layer studded with tiny calcium stones called otoconia. It is the displacement of the stones causes the hair cells to bend, when the head is tilted or the body position is changed with respect to gravity.
By the way, the balance system works with the visual and skeletal systems to maintain orientation or balance.
Visual signals are sent to the brain about the body’s position in relation to its surroundings.
These signals are processed by the brain, and compared to information from the vestibular and the skeletal systems. Besides, an example of interaction between the visual and vestibular systems is called the vestibular ocular reflex. Of course the nystagmus that occurs when a person is spun around and hereupon suddenly stops is an example of a ‘vestibularocular’ reflex. Did you know that an individual has difficulty maintaining orientation, when balance is impaired. Individual may experience the room spinning and may not be able to walk without staggering, or may not even be able to arise. Remember, most of the symptoms a person with a balance disorder may experience are. Sensation of dizziness or vertigo. Falling or a feeling of falling. Lightheadedness or feeling woozy. Visual blurring. Disorientation. Symptoms may appear and disappear over short time periods or may last for a longer term. Infections, head injury, disorders of blood circulation affecting the inner ear or brain, certain medications, and aging may change our balance system and result in a balance problem. Individuals who have illnesses, brain disorders, or injuries of the visual or skeletal systems, similar to eye muscle imbalance and arthritis, may also experience balance difficulties. Conflict of signals to the brain about the sensation of movement can cause motion sickness. Let me tell you something.a big problem in the brain or its connecting nerves.
Systemic disorder, a significant problem of the body except the head and brain. Vascular disorder, or blood flow problems. Benign Paroxysmal Positional Vertigo -a brief, intense sensation of vertigo that occurs because of a specific positional change of the head. Now, an individual may experience BPPV when rolling over to the left or right upon getting out of bed in the morning, or when looking up for an object on a high shelf. This is the case. Albeit it might be caused by an inner ear infection, the cause of BPPV ain’t known, head injury, or aging. Labyrinthitis an infection or inflammation of the inner ear causing dizziness and loss of balance. Needless to say, while fluctuating hearing loss, tinnitus, and the sensation of fullness in the ear, s diseasean inner ear fluid balance disorder that causes episodes of vertigo. Therefore the cause of Ménière’s disease is unknown. Vestibular neuronitis an infection of the vestibular nerve, generally viral. Now look. Perilymph ‘fistulaa’ leakage of inner ear fluid to the middle ear.
Without a known cause, it can occur after head injury. Rarely.
Diagnosis of a balance disorder is complicated as long as there are many kinds of balance disorders and as long as other medical conditionsincluding ear infections, blood pressure changes, and some vision problemsand person experiencing dizziness should see a physician for an evaluation. Actually the primary physician may request the opinion of an otolaryngologist to neck. Anyway, s/he will usually obtain a detailed medical history and perform a physical examination to start to sort out possible causes of the balance disorder.
Physician may require tests to assess the cause and extent of the disruption of balance.
The kinds of tests needed will vary depending on the patient’s symptoms and health status.
Not all patients will require each test, because there’re so many variables. You see, By the way, the caloric test might be performed as part of the ENG. And therefore the amount of nystagmus resulting is measured, In this test, any ear is flushed with warm and later cool water, usually one ear at a time. Weak nystagmus or the absence of nystagmus may indicate an inner ear disorder.
Body sway is recorded in response to movement of the platform as well as the visual environment, Another test of the vestibular system, posturography, requires the individual to stand on a special platform capable of movement within a controlled visual environment.
Mostly there’re various options for treating balance disorders.
One option includes treatment for a disease or disorder that should be contributing to the balance problem, just like ear infection, stroke, or multiple sclerosis. Then, individual treatment will vary and going to be based upon symptoms, medical history, general health, examination by a physician, and the results of medical tests. Another treatment option includes balance retraining exercises. Anyways, the exercises include movements of the head and body specifically developed for the patient. Now this form of therapy is thought to promote compensation for the disorder. Therefore, vestibular retraining programs are administered by professionals with knowledge and understanding of the vestibular system and its relationship with other systems in the body. For people diagnosed with Ménière’s disease, dietary changes like reducing intake of sodium may help. For example, while reducing alcohol, caffeine, as well as avoiding nicotine might be helpful, for many. Some aminoglycoside antibiotics, like gentamicin and streptomycin, are used to treat Ménière’s disease.
Systemic streptomycin and pical gentamicin are useful for their ability to affect the hair cells of the balance system.
Gentamicin also can affect the hair cells of the cochlea, though, and cause hearing loss.
In cases that do not respond to medical management, surgery should be indicated. Program of talk therapy as well as physical rehabilitation can be recommended for people with anxiety. Fact, you can take the following steps that should be helpful to your physician in determining a diagnosis and treatment plan. Bring a written list of symptoms to your doctor. Bring a list of medications currently being used for balance disorders to your doctor. I’m sure it sounds familiar. Be specific when you describe the nature of your symptoms to your doctor. Although, describe how, when, and where you experience dizziness. Lastly, remember to write down any instructions or tips your doctor gives you.
Scientists are working to have a grasp of the various balance disorders and the complex interactions between the labyrinth, other ‘balancesensing’ organs, and the brain.
Scientists are studying eye movement to know the changes that occur in aging, disease, and injury.
Scientists are collecting data about eye movement and posture to improve diagnosis and treatment of balance disorders. Scientists are also studying the effectiveness of certain exercises as a treatment option. Recent findings from studies supported by the National Institute on Deafness and Other Communication Disorders suggest that the vestibular system plays an important role in modulating blood pressure. Now pay attention please. Basically the information from these studies has potential clinical relevance in understanding and managing orthostatic hypotension. Other studies of the otolithic organs, the detectors of linear movement, are exploring how these organs differentiate between downward motion from linear motion. Other projects supported by NIDCD include studies of the genes essential to normal development and function in the vestibular system.
Scientists are also studying inherited syndromes of the brain that affect balance and coordination.
The Institute supports research to develop new tests and refine current tests of balance and vestibular function.
Scientists have developed ‘computer controlled’ systems to measure eye movement and body position by stimulating specific parts of the vestibular and nervous systems. As well as new physical rehabilitation strategies, other tests to determine disability are under investigation in clinical and research settings. NIDCD, gether with other Institutes at the National Institutes of Health, joined the National Aeronautics and Space Administration for Neurolab, a research mission dedicated to the study of life sciences. Certainly, neurolab focused on the most complex and least understood part of the human body, the nervous system. Exposure to the weightlessness of space is known to temporarily disrupt balance on return to Earth and to gravity.
These studies did not include an aged individual, A team of NIDCD and NASA investigators had previously studied the effects of microgravity exposure on balance control in astronauts who had returned from ‘shortduration’ space flight missions.
Throughout the October 29 November 7, 1998, Space Shuttle Discovery mission, NIDCD and NASA collaborated in another study of postflight balance control.
Now elderly astronaut, Senator John Glenn, participated, for the first time, a previously experienced. As a result, data collected during this mission, that are still being analyzed, may a similar occurrence among people with balance disorders, particularly as they grow older.
