Hearing loss and dementia are two conditions that can be common among aging adults, but recent research suggests the two may be more interconnected than previously thought.
Recent studies have shown that untreated hearing loss can lead to cognitive decline and, in some cases, dementia, but fortunately, there are things that can be done to slow this decline and protect brain health.
Let’s explore who is most at risk for dementia due to hearing loss, why this link exists, and how a visit to your local audiologist can help mitigate your risk.
In 2011, experts at Johns Hopkins University conducted a study that tracked 639 adults for nearly 12 years and found that individuals with mild hearing loss were nearly twice as likely to develop dementia, while those with severe hearing loss had up to five times the risk.
A separate study published in 2020 found that hearing loss is responsible for 8% of global dementia cases, which also makes it the most preventable risk factor in a given population.
While the evidence for this connection between hearing loss and dementia is vast, researchers are not exactly sure why this connection exists in the first place, but most agree that social isolation plays a major role.
Our brains evolved for social interaction, and studies show that reduced participation in social events can lead to cognitive decline. As a result, individuals with moderate to severe hearing loss are subject to reduced stimulation in the brain’s auditory cortex, which can then lead to a higher likelihood of dementia.
While hearing loss and dementia can affect anyone, certain groups, like older adults and individuals with untreated hearing loss, are at a much higher risk because
It may seem like the dangers are exceptionally high, but the good news is that research suggests that treating hearing loss with hearing aids can slow down or even reduce the risk of dementia.
The sad case is that many people don’t realize they have hearing loss until it significantly impacts their daily lives, and the earlier it is detected and treated, the better the chances of mitigating its effects on cognition.
Here are some signs that it may be time for a hearing test include:
- Frequently asking people to repeat themselves
- Struggling to hear in noisy environments
- Turning the TV or radio volume up higher than others prefer
- Feeling exhausted after conversations
- Avoiding social situations due to difficulty hearing
If you or a loved one are diagnosed with hearing loss, then it is imperative that you address it by taking proactive steps to reduce your risk of dementia and other cognitive health concerns.
If you’re struggling to hear and don’t yet have hearing aids, consider getting them, but if you already have hearing aids, wear them consistently. If they aren’t functioning properly, stop in to get them cleaned and if worst comes to worst, repaired or replaced.
Beyond addressing your hearing, staying socially active is crucial. Engage in conversations, participate in group activities, and maintain an active lifestyle because these simple actions not only protect your cognitive health but also promote a more positive lifestyle.
