Do You Have Presbycusis - Age-Related Hearing Loss?

Mar 13, 2023

As we age, it's natural for our bodies to experience some wear and tear. One of the most common age-related conditions is hearing loss. If left untreated, this hearing condition can make it difficult for seniors to understand speech, engage in social activities which can lead to social isolation, depression and other negative health outcomes.

Presbycusis, or age-related hearing loss is a gradual and progressive hearing loss that occurs as a result of aging. It primarily affects the ability to hear high-frequency sounds, making it difficult to understand speech and distinguish certain sounds. This type of hearing loss is often associated with natural wear and tear of the sensory cells in the inner ear and changes in the auditory pathways that transmit sound signals to the brain.

Causes of Presbycusis

While the exact cause of presbycusis is still not fully understood, there are several factors that contribute to its development. These include:

  1. Age-related Changes: As we age, the structures of the inner ear, including the hair cells, are responsible for converting sound vibrations into electrical signals, which become less efficient and can deteriorate over time.
  2. Genetics: Genetic factors can play a role in determining an individual's susceptibility to age-related hearing loss. If there is a family history of presbycusis, the chances of developing the condition may be higher.
  3. Noise Exposure: Prolonged exposure to loud noises throughout one's life can damage the delicate structures of the inner ear and contribute to hearing loss.
  4. Medical Conditions: Certain medical conditions, such as diabetes, cardiovascular disease, and high blood pressure, can increase the risk of developing presbycusis.

Risk Factors of Age-Related Hearing Loss

According to the World Health Organization (WHO), it is estimated that around one in three people between the ages of 65 and 74 have some degree of hearing loss, and this number increases to almost half of the population over the age of 75.

While the exact cause of presbycusis is not fully understood yet, here are the most common risk factors:

  • Aging: As we age, the tiny hair cells in the inner ear which are responsible for sending sound signals to the brain can become damaged and die off, leading to hearing loss.
  • Gender: Men are more likely to experience age-related hearing loss than women. One study found that men were 1.5 times more likely to have hearing loss than women. This may be due to a combination of factors, including occupational noise exposure and genetic differences.
  • Genetics: Hearing loss can run in families. Those with a family history of hearing loss may be more likely to develop presbycusis themselves.
  • Exposure to Loud Noises: People who are frequently exposed to loud noise with hearing protection, whether through occupational or recreational activities can damage the delicate hair cells in the inner ear which are responsible for transmitting sound to the brain. Those who regularly attend concerts, listening to loud music using headphones are also at an increased risk of developing early onset of presbycusis.
  • Smoking: The chemicals in cigarettes can damage the delicate hair cells in the inner ear, leading to permanent hearing loss.
  • Pre-Existing Medical Conditions: Certain medical conditions, such as high blood pressure, diabetes, and cardiovascular disease can affect blood flow to the ears, which can lead to hearing loss.
  • Poor Nutrition: The cochlea is a part of the inner ear that is responsible for transmitting sound signals to the brain. It requires proper nutrition to function effectively. Poor nutrition can lead to damage to the cochlea, which may result in hearing loss.
  • Ototoxic Medications: Antibiotics and chemotherapy drugs can increase the risk of presbycusis by causing oxidative stress in the body. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. This imbalance can lead to cellular damage, including damage to the hair cells in the inner ear. It is important to note that not all medications are toxic to the ear.

Signs and Symptoms of Hearing Loss in Elderly

Here are some common symptoms of age-related hearing loss:

  • Asking people to repeat themselves or speak louder.
  • Avoiding social situations because of difficulty hearing.
  • Difficulty hearing women's or children's voices.
  • Difficulty understanding speech, especially in noisy environments.
  • Feeling like people are mumbling or speaking unclearly most of the time.
  • Feeling like sounds are muffled or distorted.
  • Misunderstanding or misinterpreting conversations
  • Tinnitus, or ringing in the ears.
  • Turning up the volume on the television or radio.
  • Trouble hearing high-pitched sounds, such as a ringing phone or doorbell.

Diagnosis and Treatment Options for Presbycusis

If you suspect you may have presbycusis, it is essential to consult a hearing care professional for a comprehensive evaluation. They will conduct various tests, including a hearing test, to assess the extent and nature of your hearing loss. Based on the results, they will recommend suitable treatment options, which may include:

  • Hearing Aids: These are small electronic devices that amplify sounds, making them easier to hear. Modern hearing aids come in various styles and can be customized to meet individual needs.
  • Assistive Listening Devices: These devices are designed to enhance specific listening situations, such as hearing loops, FM systems, or Bluetooth-enabled accessories that connect to televisions or smartphones.
  • Communication Strategies: Learning effective communication techniques, such as using visual cues or lip-reading, can help improve understanding in challenging listening environments.

  • Cochlear Implants: In severe cases of hearing loss where hearing aids don't provide any benefit after 6 months of hearing aid trials, implants may be considered. These devices bypass damaged portions of the inner ear and stimulate the auditory nerve directly.
If you or a loved one is experiencing any of these symptoms, it is essential to see a hearing care professional to evaluate the degree and type of hearing loss. Early intervention can improve communication, enhance overall quality of life, and reduce the risk of social isolation and depression.
