Differences From Prior Studies Of Human Presbycusis

Most forms of acquired hearing loss, including presbycusis, arise in the inner ear, but understanding the underlying damage is limited by the inability to biopsy the inner ear or to reveal cellular detail noninvasively. Prior studies of human otopathology have been case-based, and the relations between histopathology and hearing loss have rarely been quantitatively examined. A rigorous understanding of these relationships is increasingly important, as biological therapeutics for inner ear disorders are on the horizon, and subject-inclusion criteria depend on predicting the degree and pattern of hair cell or neural loss from noninvasive tests of hearing function.

Almost all human presbycusis studies are based on light-microscopic evaluation of semiserial temporal-bone sections. However, prior studies have binarized the hair cell analysis, rating cell survival in each section as either 0% or 100% . Using high-power DIC objectives to optically section the slides, we assessed fractional survival of hair cells , and conclusions from the two approaches dramatically differ . In a binarized analysis, only complete hair cell loss is noted . Thus, Schuknecht’s influential studies of presbycusis concluded that hair cell loss rarely explains the audiometric pattern, and that strial degeneration or neuronal loss is more often responsible.

How Can I Tell If I Have A Hearing Problem

Ask yourself the following questions. If you answer “yes” to three or more of these questions, you could have a hearing problem and may need to have your hearing checked.

Diagnosis And Treatment Of Age

Visit your health care provider as soon as you experience any of the above-mentioned symptoms. They will use an otoscope to check whether there is any damage in the eardrum or blockage in the ear canal due to ear wax, inflammation, or infection. They will refer you to an audiologist if your condition is worse. The audiologist will perform a hearing test to determine the degree of your hearing loss and recommend the suitable hearing aid or treatment accordingly.

Your audiologist may perform one of these tests to diagnose your hearing loss:

  • Traditional pure tone test
  • Speech in noise test
  • Tympanometry test

The type of treatment you will require to overcome your hearing loss varies depending on your age and the degree of hearing loss you have. Hearing aids are considered the best solution for most types of hearing loss. Even adults aged 70 and older can benefit from wearing hearing aids. There are different types of hearing aids to select from. Discuss your options with your audiologist and choose the one that suits your lifestyle, hearing ability, and budget.

Hearing aids may be recommended for some individuals. Assistive listening devices can provide further improvement in hearing ability in certain situations.

One example of such a device is the built-in telephone amplifier. Another example is FM systems that make sounds clearer, with or without a hearing aid, by delivering sound waves like a radio.

Training in speechreading can help those with presbycusis to understand better what is being said in conversations or presentations.

Signs Of Hearing Loss

Some people have a hearing problem and dont realize it. You should see your doctor if you:

  • Have trouble hearing over the telephone
  • Find it hard to follow conversations when two or more people are talking
  • Often ask people to repeat what they are saying
  • Need to turn up the TV volume so loud that others complain
  • Have a problem hearing because of background noise
  • Think that others seem to mumble
  • Cant understand when women and children speak to you

Can I Prevent Hearing Loss Associated With Old Age

While you cant do anything about your relatives , you can take steps to prevent some lifestyle factors linked to hearing loss.

  • If youre diabetic, have heart disease or other circulatory problems, follow your doctors guidelines for diet and exercise. The hair cells in the inner ear depend on good blood flow to keep them healthy. Maintaining a healthy weight and exercising regularly can facilitate hearing health.
  • Ask your doctor about the medications youre taking. Are they linked to hearing loss? If so, ask if she can prescribe an alternative medication. If you take large amounts of aspirin or other pain relievers, cut back or try to find alternative methods of pain relief.
  • Be aware of loud noises in your environment. According to the NIDCD, noise-induced hearing loss is the only type of hearing loss that is completely preventable. Sounds measuring more than 85 decibels for long or repeated periods of time can permanently damage your hearing. Hearing health experts recommend wearing ear plugs or other hearing protection when youre working or playing around noisy equipment or recreational vehicles. If you cant reduce the noise or protect your ears, move away from it.

Is There A Cure For Presbycusis

Not hearing as well as you once did? Itcould be age-related hearing loss.

Like most types of sensorineural hearing loss, there is no cure. Fortunately, though, most cases of sensorineural hearing loss can be treated.

  • Hearing aids. Those with mild-to-moderate hearing loss may benefit from wearing hearing aids. After a thorough hearing evaluation, a hearing healthcare professional will recommend the type and style of hearing aid according to the severity of your hearing loss, lifestyle preferences and budget.
  • Cochlear implants, which can be given to older adults. If you are diagnosed with severe or profound hearing loss, you may benefit from using a cochlear implant. These medical devices are surgically implanted behind your ear to help detect sound and understand speech.
  • Assistive listening devices . Technology is available to amplify sound from your television, telephone and other personal electronic devices. ALDs can be used with or without hearing aids, depending on the type and severity of your hearing loss.

What Should I Do If I Have Trouble Hearing

Hearing problems can be serious. The most important thing you can do if you think you have a hearing problem is to seek advice from a health care provider. There are several types of professionals who can help you. You might want to start with your primary care physician, an otolaryngologist, an audiologist, or a hearing aid specialist. Each has a different type of training and expertise. Each can be an important part of your hearing health care.

  • An otolaryngologist is a doctor who specializes in diagnosing and treating diseases of the ear, nose, throat, and neck. An otolaryngologist, sometimes called an ENT, will try to find out why you’re having trouble hearing and offer treatment options. He or she may also refer you to another hearing professional, an audiologist.
  • An audiologist has specialized training in identifying and measuring the type and degree of hearing loss. Some audiologists may be licensed to fit hearing aids.
  • A hearing aid specialist is someone who is licensed by your state to conduct and evaluate basic hearing tests, offer counseling, and fit and test hearing aids.

Age Related Hearing Loss: Symptoms, Causes, Treatment in ...

Hearing loss often begins when you are in your thirties or forties and worsens over time. As the hearing loss is gradual, you may not realize it until it worsens. A combination of lifestyle, genetic, and environmental factors gradually wear down your ears’ delicate mechanics.

Factors that cause hearing loss include:

  • Exposure to loud noises
  • Impairment in the nerves responsible for hearing
  • Changes in the structures of the inner ear
  • Changes in the blood flow to the ear

Signs And Symptoms Of Age

What are the signs and symptoms of an age-related hearing loss? With age-related hearing impairment there are certain typical signs to look out for.

Age-related hearing loss develops slowly and gradually, so normally we do not notice the decline in our ability to hear. Most people with age-related hearing loss first experience a decline in their ability to hear high frequency sounds.

The Mechanisms Of Aging In The Peripheral Auditory System

The inner ear is more vulnerable to age-related changes than both the external and middle ear . Hence, pathophysiological changes related to cochlea and afferent neurons are discussed here. Based on underlying case history information, audiometric configurations, and temporal bone analyses, Schuknecht divided ARHL into four distinct classes: sensory , neural , strial , and cochlear conductive . Rapid high-frequency sloping hearing loss, flat hearing loss, poor word discrimination and gradual hearing loss with no pathological evidence are characteristics of sensory, strial, neural, and cochlear conductive presbycusis, respectively . Later, Schuknecht and Gacek added two more categories: mixed-consisting of a mixture of pathological characteristics and indeterminate-consisting of none of the aforementioned pathological characteristics. Contrary to the above-mentioned findings, Allen and Eddins reported that hearing phenotypes do not naturally form distinct classes of ARHL and rather form a continuum. However, subtypes of ARHL can still be identified if the distribution of data are in the extremes of either flat or sloping loss .

When To Contact A Medical Professional

Hearing loss should be checked as soon as possible. This helps rule out causes such as too much wax in the ear or side effects of medicines. Your provider should have you get a hearing test.

Contact your provider right away if you have a sudden change in your hearing or hearing loss with other symptoms, such as:

  • Headache

Types Of Hearing Loss

Age-Related Hearing Loss (Presbycusis)

Hearing loss comes in many forms. It can range from a mild loss, in which a person misses certain high-pitched sounds, such as the voices of women and children, to a total loss of hearing.

There are two general categories of hearing loss:

  • Sensorineural hearing loss occurs when there is damage to the inner ear or the auditory nerve. This type of hearing loss is usually permanent.
  • Conductive hearing loss occurs when sound waves cannot reach the inner ear. The cause may be earwax buildup, fluid, or a punctured eardrum. Medical treatment or surgery can usually restore conductive hearing loss.

We All Lose Our Hearing

One of the major causes of hearing loss is ageing. Hearing loss is a natural consequence of getting older. As you get older, the hair cells in your inner ear begin to die and when more and more hair cells die our hearing gets worse and worse. This happens to all of us and we all begin to lose our hearing when we are in our 30’s and 40’s.Some people lose their hearing and get an age-related hearing loss earlier and faster than others. Around the age of 50, we see that more and more people get age-related hearing loss. Age-related hearing loss is especially common among people in their 60’s and 70’s. Age-related hearing loss is also called Presbyacusis. The treatment for age-related hearing loss is always hearing aids.

Causes Of Hearing Loss

Loud noise is one of the most common causes of hearing loss. Noise from lawn mowers, snow blowers, or loud music can damage the inner ear, resulting in permanent hearing loss. Loud noise also contributes to tinnitus. You can prevent most noise-related hearing loss. Protect yourself by turning down the sound on your stereo, television, or headphones moving away from loud noise or using earplugs or other ear protection.

Earwax or fluid buildup can block sounds that are carried from the eardrum to the inner ear. If wax blockage is a problem, talk with your doctor. He or she may suggest mild treatments to soften earwax.

A punctured ear drum can also cause hearing loss. The eardrum can be damaged by infection, pressure, or putting objects in the ear, including cotton-tipped swabs. See your doctor if you have pain or fluid draining from the ear.

Health conditions common in older people, such as diabetes or high blood pressure, can contribute to hearing loss. Viruses and bacteria , a heart condition, stroke, brain injury, or a tumor may also affect your hearing.

Hearing loss can also result from taking certain medications. Ototoxic medications damage the inner ear, sometimes permanently. Some ototoxic drugs include medicines used to treat serious infections, cancer, and heart disease. Some antibiotics are ototoxic. Even aspirin at some dosages can cause problems. Check with your doctor if you notice a problem while taking a medication.

Deafness And Hearing Loss: Age

In the initial stages, a person with hearing loss may have difficulty in understanding words. He/she is often able to hear the sounds but unable to make out the words. This may be more evident when the background noise is high .

Such a person may also start speaking in a louder voice than normal, without being aware of it.

A ringing sensation in the ear and inability to hear high pitched sounds can also indicate presbycusis.

You should get your ears tested if:

  • you often have to ask people to repeat themselves
  • find yourself raising the volume of the television to higher than normal levels
  • regularly miss parts of conversations
  • experience a ringing sensation in the ear
  • people tell you that you are speaking loudly.

What Are The Symptoms Of Age

Age Related Hearing Loss Symptoms, Causes

The following are the most common symptoms of age-related hearing loss:

  • Speech of others sounds mumbled or slurred

  • High-pitched sounds, such as “s” or “th” are hard to distinguish

  • Conversations are difficult to understand, particularly when there is background noise

  • Men’s voices are easier to hear than women’s

  • Some sounds seem overly loud and annoying

  • Tinnitus may occur in one or both ears

The symptoms of age-related hearing loss may look like other conditions or medical problems. Always consult your health care provider for a diagnosis.

Can I Prevent Age

At this time, scientists don’t know how to prevent age-related hearing loss. However, you can protect yourself from noise-induced hearing loss by protecting your ears from sounds that are too loud and last too long. It’s important to be aware of potential sources of damaging noises, such as loud music, firearms, snowmobiles, lawn mowers, and leaf blowers. Avoiding loud noises, reducing the amount of time you’re exposed to loud noise, and protecting your ears with ear plugs or ear muffs are easy things you can do to protect your hearing and limit the amount of hearing you might lose as you get older.

The 3 Most Common Causes Of Hearing Loss

About one in eight Americans have hearing loss in both ears, according to the National Institute on Deafness and Other Communication Disorders. But there are three types of hearing loss that are the most common.

The Centers for Disease Control and Prevention reports that 1.7 in 1,000 babies screened for hearing loss will have hearing issues. Genetic hearing loss is the most common cause of hearing loss in babies and children. In adults, age-related hearing loss becomes increasingly common, with 8.5% of adults aged 55 to 64 experiencing disabling hearing loss. Knowing the most common causes of hearing loss can help you seek treatment as early as possible.
