How are Dementia, Hearing Loss & Hearing Aids Connected?

Dementia, generally defined as a decline in cognitive abilities, is a subject of extensive research. Present studies are investigating the possible connection between dementia and hearing loss. Research indicates that hearing aids can potentially enhance cognitive functions. At Applied Hearing Solutions, our audiologists provide a variety of hearing services and maintain best practices in fitting hearing aids.

What is Dementia?

Dementia mainly impacts cognitive abilities such as memory, problem-solving, and self-management. While it is most prevalent among the elderly, early signs can also appear in adults. There are many forms of dementia, with Alzheimer's being the most common. It's crucial to understand that dementia is typically irreversible, but steps can be taken to decelerate its progression. Treating hearing loss with the use of hearing aids is one crucial part.

The Intricate Connection Between Dementia and Hearing Loss

Recent studies suggest a possible connection between hearing loss and dementia. A French research project, which tracked 3,800 participants over a span of 25 years, discovered that older individuals with untreated hearing loss were more likely to develop dementia. This is a significant finding, given that nearly two-thirds of American seniors are diagnosed with hearing loss. However, it's crucial to note that hearing loss does not automatically result in dementia. The same research indicated that individuals using hearing aids were less susceptible to rapid cognitive decline.

The Role of Hearing Loss in Cognitive Decline

Untreated hearing loss is a barrier when socializing, especially in noisier settings. When it's difficult to hear, and you have to fake your way through a conversation, social interactions are not pleasant. This is just one of the challenges faced by those with untreated hearing loss. Behind the scenes, several things may be happening in this relationship between your hearing and your cognitive abilities.

1. Cognitive overload refers to a situation where the lack or absence of a particular sense - in this case, hearing - can trigger neurological stress. This typically occurs when the brain is forced to work overtime, exerting extra effort to comprehend its surroundings. In doing so, it diverts valuable resources away from other critical tasks, such as memory retention and recall. Over a prolonged period, this excessive diversion of resources can lead to a noticeable decline in these essential cognitive functions.
2. Neurological restructuring occurs naturally when our brains adjust to tackle challenges. As a sense begins to diminish, the brain restructures, drawing resources from other regions, potentially increasing the risk of dementia.
3. Social isolation is often a result of untreated hearing loss. Extended periods of isolation can lead to a deterioration in language and memory abilities, as well as other mental health problems such as depression. This, in turn, heightens the risk of dementia.

How Hearing Aids Can Support Your Brain

People who use hearing aids, prescribed and fitted by an audiologist, are generally at lower risk of developing dementia. Cognitively, their brains receive more stimulation from the use of such aids. Basic activities like conversations, hobbies, and outdoor pursuits play an essential role in maintaining overall health.

Hearing aids play a crucial role in supporting cognitive health by positively influencing the brain's function. When left untreated, hearing loss can lead to a reduced auditory input to the brain, contributing to cognitive decline and an increased risk of conditions like dementia. Hearing aids, by amplifying and enhancing sounds, provide a clearer and more complete auditory experience. This improved input stimulates the auditory pathways in the brain, preventing auditory deprivation and maintaining neural connections.

Studies have suggested that wearing hearing aids may contribute to better cognitive performance, memory retention, and overall brain health. By addressing hearing loss, these devices not only enhance one's ability to hear but also actively support the brain's cognitive functions, promoting a healthier and more engaged mind throughout life. A simple annual hearing test with an audiologist can be the first step toward strengthening your cognitive abilities.

If a hearing loss is detected, our audiologists will recommend the many exciting hearing aid options available to you. And this is an exciting time for hearing aids! Advances in technology have led to a number of features that not only enhance your hearing but also seamlessly connect with your tech devices. Many devices offer full connectivity, allowing users to stream audio and phone calls directly to their hearing aids. Sleeker, smaller design and portable rechargeability make hearing aids a more appealing choice than ever before.
