The Effects of Hearing Loss
Hearing loss is a common condition that affects millions of people worldwide.
A 2020 Lancet study found that untreated hearing loss is associated with a higher risk of cognitive decline and dementia. The study followed over 8,000 adults for 25 years and found that those with untreated hearing loss had a 33% higher risk of developing dementia compared to those without hearing loss.The link between hearing loss and cognitive decline is further supported by a 2023 JAMA article, which suggests that hearing loss can affect brain function, leading to decreased cognitive abilities.
The article highlights the importance of early identification and treatment of hearing loss to prevent or delay cognitive decline. Hearing loss can have a significant impact on cognitive function in several ways. It can lead to difficulty in understanding speech, especially in noisy environments. This can cause mental exhaustion and a decline in cognitive function over time. Additionally, the brain's ability to recognize and distinguish between different sounds may decrease as hearing loss progresses, leading to difficulties in understanding and remembering speech.
The effects of hearing loss on cognitive function can be prevented or delayed by early identification and treatment.
The use of hearing aids is an effective way to improve hearing ability and prevent the negative effects of hearing loss on cognition. Multiple studies have shown that the use of hearing aids can improve cognitive function and quality of life for individuals with hearing loss. It is crucial to raise awareness about the connection between hearing loss and cognitive decline and encourage regular hearing checks, especially for older adults.
By identifying and treating hearing loss early, individuals can prevent or delay cognitive decline, improving their quality of life and maintaining their independence.In conclusion, hearing loss has a significant impact on cognitive function, and it's essential to address it early to prevent or delay cognitive decline.
The current research suggests that untreated hearing loss increases the risk of developing dementia, but the use of hearing aids can help maintain cognitive function and quality of life. Regular hearing checks are critical, and early identification and treatment of hearing loss can make a significant difference in an individual's overall health and well-being.
Since most hearing loss develops gradually over time, it can be difficult to know how well you are hearing now compared with how well you used to hear. Only an accurate hearing test can reveal if you are having difficulty with specific sounds, and if so, how you might be able to hear better.
Social Effects of Hearing Loss
Those suffering from hearing loss often begin to notice their difficulty in the following circumstances:
- Hearing conversations in large groups
- Participating in conversation in restaurants or other settings with background noise
- Hearing on the telephone
- Understanding women’s and children’s voices
Party settings and even small family gatherings can strain hearing to the point where the additional mental effort required to decode what seems like broken speech can become tiresome. Eventually such social situations can become so difficult that those experiencing hearing loss may begin to withdraw from them altogether. Individuals instead begin to prefer less demanding, quieter settings — often away from the precious social contact that enriches our lives and draws us closer to the ones we love.
The stress of living with hearing loss, too, can have its own consequences:
- Distrust of others
- Anger at not feeling understood
- Feeling socially marginalized
Reluctance to seek treatment or to wear hearing aids can cause additional stress when individuals — often unconsciously — wish to conceal their hearing loss, and potentially miss out on important communications. Compromised hearing in the workplace, for instance, can have significant effects on job performance and even earning potential.
Physical Effects of Hearing Loss
Untreated hearing loss over extended periods of time can have damaging physical effects, as well, when the auditory system goes unused. Auditory deprivation, as audiologists refer to it, leaves nerves and portions of the brain underused, and — like other parts of the body — if the auditory system goes unused, it can begin to atrophy. Without fail, in our experience, the longer a patient waits to address their hearing loss, the more difficult it is to recover one’s ability to communicate.
Increasing Evidence Connects Hearing Loss to Dementia
Additionally, increasing evidence points to a connection between hearing loss and cognitive decline in older adults. According to a study published in January 2013 in JAMA Internal Medicine, adults in their 70s and 80s with hearing loss developed cognitive problems at a rate 30 to 40 percent faster than those without hearing loss. While the reason for this apparent connect remains unknown, researchers have speculated that social isolation might be a factor. The additional mental demands of having to constantly decode speech might also be a contributing factor to the types of cognitive changes that, over time, can lead to the onset of dementia.
