Prevalence

According to the National Institute of Health, nearly 90 million Americans report episodes of dizziness at some point in their lives. This figure translates into more than 8 million physician visits per year from people seeking help for their dizziness problems. As we get older, balance disorders are even more prevalent. The National Institute on Aging reports one third of people over the age of 65 falls at least once per year. Other studies indicate that balance and mobility disorders are the most frequent cause of chronic disability among the elderly and that 60% of all emergency room visits by the elderly are due to falls.

Disorders of balance and dizziness can have a significant impact on peoples’ lives beyond the obvious feeling of instability. Many patients report an inability to concentrate on various tasks, experience memory problems, as well as having increased tension due to fear of falling. These added problems occur because for most individuals, maintaining balance is an automatic function, requiring very little active thought process or energy. In contrast, people suffering from dizziness and imbalance allocate a great amount of energy to avoid falling. In some cases, dizziness and balance problems can result in withdrawal and isolation. Many people are hesitant to move in certain positions because it results in dizziness. Their overall activity level diminishes, which in turn causes more deterioration of their functional mobility. This creates a cycle of increased dependence on others which can lead to other psycho-social difficulties.

Diagnosis and Management

Unfortunately, the diagnosis and treatment of dizziness and balance problems is extremely challenging. People with chronic long-term dizziness see an average of five physicians for their condition. This is because dizziness can result from many different causes including interaction of medications, disturbances within the inner ear, diseases of the respiratory or cardiac systems, or tumors in the central nervous system. That’s why there needs to be a coordinated effort between your physician and medical experts specifically trained to handle the diagnosis and management of dizziness problems.

By virtue of their training and experience the otolaryngologists at The Ear, Nose & Throat Associates of Manatee are uniquely qualified to handle disorders of balance and dizziness. By obtaining a comprehensive medical history, clinical evaluation, laboratory tests and diagnostic evaluations these specialists can diagnose and treat your problems with success.

No Simple Task

We’ve all heard of the clumsy kid in high school who “can’t walk and chew gum at the same time”. However, the more we know about this process, the greater appreciation we have for the complexity of this task. Balance is an interaction of sensory centers within the inner ear or vestibular system, vision, and somatosensory input (information coming from the legs, feet and sensors within tendons and joints). All of this information is processed within the brain so that the appropriate interpretation of the world around you can take place. If there is damage or compromised function of one or more of these sensory systems, the brain misinterprets the information which results in instability. Fortunately, with recent advances in diagnostic equipment and therapy techniques, there is now help for those suffering from the debilitating effects of dizziness.

Vestibular Rehabilitation

Vestibular rehabilitation is an individualized approach of specific therapy protocols to help the patient overcome problems of dizziness and imbalance. Following a battery of diagnostic testing and examination by a physician, deficits within the various systems contributing to balance (vestibular, vision and somatosensory) are determined and a specific program is developed. This approach is a “symptom driven” program to help the individual overcome or improve in the areas of daily living where they are having problems. A thorough history, as well as, functional exam of current abilities and disabilities is completed. Vestibular rehabilitation also differs from many standard treatments of dizziness in that the use of medications to treat the symptoms is discouraged. Long-term use of medications under certain conditions, can even have the effect of making symptoms worse or delaying recovery.

Candidacy

Patients who seem to respond best to vestibular rehabilitation are those with a history of a generalized state of disequilibrium, motion provoked dizziness caused by changes in head or body position “every time I roll over to the right in bed, I get dizzy”, or have documented vestibular deficits within the inner ear system based on test results. Chronic conditions that have been present for a long period of time can also respond well to treatment.

Does Therapy Hurt?

No, however, it does require effort on your part. During vestibular rehabilitation, through a systematic and progressively more challenging series of head, body and eye movements, the brain learns to interpret new input from the ears, eyes and legs. At first, many individuals feel worse before they get better because they are being asked to do some of the things that bring on their symptoms of dizziness. However, with repetition, the central nervous system learns to interpret this new information, and symptoms of disequilibrium and dizziness improve. Therapy is done in an outpatient setting with individuals coming in once or twice a week. The program typically lasts only 6-10 weeks with “homework exercises” being done on a daily basis. As you might imagine, progress depends on the patients’ initial condition, motivation, and compliance with the program.

Does It Work?

Studies from major medical centers around the country reveal that improvement in functional balance and daily living activities can occur regardless of age. Although progress may be somewhat slower for someone in their 80’s, the actual amount of improvement that can be expected from this program is similar regardless of age. Approximately 75% of the patients enrolled in a vestibular rehabilitation program have significant improvement in their symptoms. This is good news for people suffering from dizziness and balance problems who are willing to invest time and energy into trying to get better.

This therapy is not for everyone. There are literally dozens of reasons why people may feel dizzy, many of which would not be appropriate for vestibular rehabilitation therapy. However, by working closely with your doctor and with referrals to specialists trained in the management of dizziness and balance, there is help for many individuals that was not available just a few short years ago.

Hearing Loss, Dizziness and Balance Disorders in the Elderly

Adults are now living longer.  But with increased longevity comes a corresponding increase in the incidence of hearing loss, dizziness and balance problems.  Each of these conditions are common problems among the senior population.  Some revealing statistics from the National Institute on Aging include: 

  • Approximately one-third of Americans between the ages of 65 and 74 have hearing problems. 
  • Nearly half the people who are 75 or older have hearing loss. 
  • As many as 40% of all adults will experience dizziness severe enough to warrant reporting it to their doctor. 

In fact, according to the National Institutes of Health, over 90 million Americans will experience dizziness or vertigo in their lifetime.  Dizziness or vertigo is the #1 complaint of patients over the age of 70, and is the third most frequent complaint among all patients after headache and back pain.  Approximately 85% of all vertigo and balance problems are due to an inner-ear incident.

Neil Aiello, Au.D., Doctor of Audiology | Columbia Basin Hearing & Balance CenterHearing loss can have many causes including aging of the auditory system, overexposure to loud noises over a period of time, infections, ear wax buildup in the ear canal, heart conditions or stroke, head injuries, tumors, certain medicines and heredity.  Common symptoms of hearing loss include; if you often can hear people talking, but simply have difficulty understanding them; struggling to hear conversations clearly in background noise or in group situations; having difficulty hearing over the telephone or needing to turn the TV volume higher so that others complain.  These Sound Voids ™ are the result of some form of hearing loss, either temporary or permanent, and may result in situations where an individual’s hearing loss does not permit them to detect or understand important sound and speech cues.  Individuals often find that Sound Voids result in tiring, frustrating, and embarrassing situations.

Dizziness is a symptom with a multitude of possible causes.  Determining the underlying cause is one of the biggest challenges for physicians.  The most common causes are related to the inner ear; therefore, referral to an audiologist is highly recommended.  Other causes include central nervous system problem in the brain or brainstem, related heart conditions, medications, as well as infections of the inner-ear or vestibular nerve.  Specificity is the key to finding the source of the problem.  The more specific you can be about when the symptoms began, when they are most likely to occur and exactly what they feel like will help the audiologist or physician develop a more accurate diagnosis.  Be aware that determining the source of dizziness is very complex and difficult to localize.  In fact, many times the exact source of the dizziness is never found.  However, more serious sources of the problem are ruled out.

According to a distinguished expert in the field of dizziness and balance disorders; Doctors of Audiology have an educational and clinical advantage in the identification and diagnosis of many forms of dizziness and vertigo problems.  The high incidence of inner ear symptoms with balance and vertigo disorders, in conjunction with the increasing number of elderly patients that need our expertise is on the rise.  In fact, many insurance companies are seeing the proven benefits and under-utilization of Doctors of Audiology who specialize in dizziness, vertigo and balance disorders.
