Understanding Hearing Loss Among Older Adults
Hearing loss is a common issue among older adults, particularly age-related hearing loss (presbycusis), which occurs gradually due to the aging process. According to the National Institute on Aging, it is one of the most prevalent conditions affecting this age group.
A July 2023 study published in JAMA Open Network reported that over 65 percent of individuals aged 71 and older experience hearing loss, with this number rising to over 96 percent by age 90. Despite the high prevalence, fewer than one in three people use hearing aids to address their hearing loss. This is concerning, as untreated hearing loss is linked to various health risks, including dementia and falls.
A December 2023 report in Lancet Healthy Longevity highlighted that regular use of hearing aids among adults with hearing loss is associated with a 24 percent reduction in the risk of early death.
The Impact of Hearing Loss
Balance and Falls: Hearing plays a crucial role in maintaining balance. Research by Dr. Frank Lin and colleagues at Johns Hopkins found that even mild hearing loss can triple the risk of falls, with the risk increasing as hearing loss worsens. Falls among older adults can significantly reduce their independence.
Cognitive Function: Mild hearing impairment doubles the likelihood of developing dementia compared to those with normal hearing. The risk increases threefold for moderate hearing loss and fivefold for severe impairment. Dr. Frank Lin’s research suggests that hearing loss makes the brain work harder to decode sounds, increasing cognitive load and potentially accelerating brain aging and cognitive decline. Additionally, hearing loss can lead to social isolation, further impacting brain health.
A January 2024 study in JAMA Otolaryngology-Head & Neck Surgery, the largest of its kind, found that untreated hearing loss is associated with a higher risk of dementia, while using hearing aids can reduce this risk.
Heart Health: Decades of research indicate a link between cardiovascular health and hearing. Dr. Raymond Hull analyzed 70 studies and found that cardiovascular problems could negatively affect hearing due to insufficient oxygen-rich blood supply to the inner ear. Dr. David R. Friedland’s research suggests that hearing loss may be an early indicator of cardiovascular disease, emphasizing the importance of maintaining heart health to prevent hearing decline.
Diabetes: According to the National Institutes of Health, hearing loss is twice as common in individuals with diabetes compared to those without. Additionally, prediabetes is associated with a 30 percent higher rate of hearing loss. Diabetes may damage the nerves and blood vessels of the inner ear, contributing to hearing impairment.
Kidney Health: A 2010 Australian study found that more than half of patients with moderate chronic kidney disease had some degree of hearing loss. Researchers believe this link is due to similarities between inner ear and kidney tissues and the potential ototoxic effects of some kidney treatments.
Protecting Your Hearing Health
Regardless of age or the cause, untreated hearing loss can adversely affect overall health. Modern Audiology Lakewood recommends regular hearing tests and the use of hearing aids when necessary. If you experience difficulties with hearing, balance, or tinnitus, schedule a visit with an audiologist or hearing aid expert.
Causes of Age-Related Hearing Loss: The National Institute on Deafness and Other Communication Disorders (NIDCD) identifies several causes of age-related hearing loss, including changes in the inner ear, middle ear, and nerve pathways, as well as prolonged noise exposure. Other factors include infections, cardiovascular conditions, head injuries, tumors, and certain medications.
Age-related hearing loss typically affects both ears equally and progresses gradually, often going unnoticed by the individual. Common signs include needing to increase the TV volume, missing words in conversations, and having difficulty using the phone.
