Falls and balance disorders are severe threats to longevity, especially as we age. Our staff at Pelican Family Medicine is sensitive to these disorders and offers patients of all ages balance assessments and rehabilitation through our comprehensive Fall Prevention Program. Please alert your Physician if you suffer from balance disorders or experience a fall. Learn more about your balance system and associated disorders below.

The Balance System
What is a balance disorder?
A balance disorder is a disturbance that causes an individual to feel unsteady, giddy, woozy, or have a sensation of movement, spinning, or floating. An organ in our inner ear, the labyrinth, is an important part of our vestibular (balance) system. The labyrinth interacts with other systems in the body, such as the visual (eyes) and skeletal (bones and joints) systems, to maintain the body’s position. These systems, along with the brain and the nervous system, can be the source of balance problems.

There are three structures in the labyrinth called the semicircular canals that let us know when we are in a rotary (circular) motion. The semicircular canals, the superior, posterior, and horizontal, are fluid-filled with a fluid called endolymph. Motion of the fluid tells us if we are moving. The semicircular canals and the visual and skeletal systems have specific functions that determine an individual’s orientation. The vestibule is the region of the inner ear where the semicircular canals converge, close to the cochlea (the hearing organ). The vestibular system works with the visual system to keep objects in focus when the head is moving. Joint and muscle receptors are also important in maintaining balance. The brain receives, interprets, and processes the information from these systems that control our balance.

How Does the Balance System Work?
Movement of fluid (endolymph) in the semicircular canals signals the brain about the direction and speed of rotation of the head like when we are nodding our head up and down or looking from right to left. Each semicircular canal has a bulbed end, or enlarged portion called the cupula, that contains hair cells. Rotation of the head causes a flow of the fluid, which in turn causes displacement of the top portion of the hair cells that are embedded in the jelly-like cupula.

Two other organs that are part of the vestibular system are the utricle and saccule. These are called the otolithic organs and are responsible for detecting linear acceleration, or movement in a straight line. The hair cells of the otolithic organs are blanketed with a jelly-like layer studded with tiny calcium crystals called otoconia. When the head is tilted or the body position is changed with respect to gravity, the displacement of the crystals causes the hair cells to bend.

The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation and balance. For example, 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. An example of interaction between the visual and vestibular systems is called the vestibular-ocular reflex. The nystagmus (an involuntary rhythmic eye movement) that occurs when a person is spun around and then suddenly stops is an example of a vestibular-ocular reflex. The nystagmus is the basis for which most diagnostic testing is measured. The intensity and the direction are key components for differentiating different dizziness and balance conditions.

What Are the Symptoms of a Balance/Dizziness Disorder?
When balance is impaired, an individual has difficulty maintaining orientation. For example, an individual may experience the “room spinning” and may not be able to walk without staggering, or may not even be able to arise. Some of the symptoms a person with a balance disorder may experience are:

A sensation of dizziness or vertigo (spinning)
Falling or a feeling of falling
Lightheadedness or feeling woozy
Visual blurring
Some individuals may also experience nausea and vomiting, diarrhea, faintness, changes in heart rate and blood pressure, fear, anxiety, or panic. Some reactions to the symptoms are fatigue, depression, and decreased concentration. The symptoms may appear and disappear over short time periods or may last for a longer period of time.

What Causes a Balance/Dizziness Disorder?
Infections (viral or bacterial), 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, such as eye muscle imbalance and arthritis, may also experience balance difficulties. A conflict of signals to the brain about the sensation of movement can cause motion sickness (for instance, when an individual tries to read while riding in a car). Some symptoms of motion sickness are dizziness, sweating, nausea, vomiting, and generalized discomfort. Balance disorders can be due to problems in any of the following four areas:

Peripheral vestibular disorder, a disturbance in the labyrinth
Central vestibular disorder, a problem in the brain or its connecting nerves
Systemic disorder, a problem of the body other than the head and brain
Vascular disorder, or blood flow problems
What Are Some of The Common Balance Disorders?
Benign Paroxysmal Positional Vertigo (BPPV)
A brief, intense sensation of vertigo that occurs because of a specific positional change of the head. 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. The cause of BPPV is not known, although it may be caused by an inner ear infection, head injury, or aging.

An infection or inflammation of the inner ear causing dizziness and loss of balance.

Ménière’s disease
An inner ear fluid balance disorder that causes episodes of vertigo, fluctuating hearing loss, tinnitus (a ringing or roaring in the ears), and the sensation of fullness in the ear. The cause of Ménière’s disease is unknown.

Vestibular neuronitis
An infection of the vestibular nerve, generally viral.

Perilymph fistula
A leakage of inner ear fluid to the middle ear. It can occur after head injury, physical exertion or, rarely, without a known cause.

How Are Balance Disorders Diagnosed?
Diagnosis of a balance disorder is complicated because there are many kinds of balance disorders and because other medical conditions, including ear infections, blood pressure changes, and some vision problems and some medications may also contribute to a balance disorder. A person experiencing dizziness should see a physician for an evaluation.

The primary physician may request the opinion of a specialist at a National Dizzy and Balance Center (NDBC) to help evaluate a balance problem. A National Dizzy and Balance Center is a clinic that specializes in diagnosing diseases and disorders of the ear, with an expertise in balance disorders. They will usually obtain a detailed medical history and perform a physical examination in order to sort out possible causes of the balance disorder. The physician may require tests to assess the cause and extent of the disruption of balance. The types of testing needed may vary based on the patient’s symptoms and health status. Because there are so many variables, not all patients will require every test.

Some examples of diagnostic tests they may request are a hearing examination, a videonystagmography (VNG–a test of the vestibular system), or imaging studies of the head and brain. A caloric test may be performed as part of the VNG. In this test, each ear is stimulated with warm and then cool air or water one ear at a time; the amount of nystagmus resulting from the stimula is measured. Weak nystagmus or the absence of nystagmus may indicate an inner ear disorder. Another test of the vestibular and balance systems is the computerized dynamic posturography (CDP). This requires the individual to stand on a special platform capable of movement within a controlled visual environment; body sway is recorded in response to movement of the platform and/or the visual environment.

How Are Balance Disorders Treated?
There are various options for treating balance disorders.

One option includes treatment for a disease or disorder that may be contributing to the balance problem, such as ear infection, stroke, or multiple sclerosis. Individual treatment will vary and will be based upon symptoms, medical history, general health, an examination by a physician, and the results of medical tests.

Another treatment option includes balance retraining exercises called vestibular rehabilitation. These exercises include movements of the head and body specifically developed for the patient. This form of therapy is thought to promote compensation for the disorder and has been proven to be very effective for most patients. Vestibular rehabilitation programs are administered by professionals with knowledge and understanding of the vestibular system and its relationship to other systems in the body.

For people diagnosed with Ménière’s disease, dietary changes such as reducing intake of sodium may help. For some people, reducing alcohol, caffeine, and/or avoiding nicotine may be helpful. Some aminoglycoside antibiotics, such as gentamicin and streptomycin, are used to treat Ménière’s disease. Systemic streptomycin (given by injection) and topical gentamicin (given directly to the inner ear) are useful for their ability to affect the hair cells of the balance system. Gentamicin can also affect the hair cells of the cochlea and cause hearing loss. In cases where medical management is not effective, surgery may be recommended.
