Recent updates from the World Health Organization (WHO) have brought the connection between hearing and brain health into sharp focus.
While health experts have recognized a link between hearing loss challenges and cognitive health for years, the latest WHO dementia risk reduction guidelines place a new emphasis on addressing hearing difficulties and using hearing aids as key interventions to help protect your cognitive health.
Hearing difficulties have been recognized as a potential risk factor since the WHO’s first dementia risk reduction guidelines in 2019. What’s significant about the latest update is that, for the first time, the WHO has specifically recommended the use of hearing aids as part of addressing this risk.
With September marking World Alzheimer’s Month, there’s no better time to understand this connection and consider the steps you can take to support your hearing and long-term brain health.
How Do Hearing Difficulties Affect the Brain?
Your brain is a powerful but busy organ. When your ears aren’t capturing sound clearly, your brain has to work harder to fill in the gaps. Think of it like trying to listen to a radio station with a fuzzy signal: you can still make out the song, but it takes much more concentration to follow it.
When you experience hearing difficulties, your brain is doing this constantly with the sounds around you. This extra effort is known as cognitive load, and it means that your brain diverts mental energy that could otherwise be used for important things such as memory, focus, and problem-solving toward interpreting and making sense of sound.
Over time, this additional mental effort places greater demands on your brain’s cognitive resources, which is one of the reasons why difficulty hearing is considered a potentially modifiable risk factor for dementia.
Hearing challenges can also affect how connected you feel to the people and activities around you. When conversations become difficult to follow, you may find yourself avoiding the social gatherings you once enjoyed, which can lead to reduced social interaction and isolation. Social isolation is an established risk factor for cognitive decline, creating a cycle that can be difficult to break.
What Does the WHO’s Update Mean for You?
The WHO’s updated guidelines recognize that proactively managing your hearing is an important part of supporting long-term brain health, placing greater emphasis on hearing care as a preventive health measure alongside other healthy lifestyle choices.
For you, this means that looking after your hearing can also help you remain socially connected, engaged in everyday life, and proactive about your long-term cognitive health.
The WHO classifies this as an emerging recommendation, meaning that the evidence linking hearing interventions to reduced dementia risk is still developing. However, this still represents a significant shift in how hearing care is viewed within the broader conversation around brain health.
Taking Control of Your Hearing Health
A comprehensive hearing assessment is a thorough evaluation designed to give you a clear picture of your hearing abilities and help identify any changes or challenges you may be experiencing. It allows our hearing care professionals to understand how well you hear different sounds, where you may be experiencing difficulties, and how your hearing could be affecting your everyday life.
Contact us today to schedule an assessment or request a callback. It’s a simple, proactive step toward understanding your hearing and supporting your long-term health.
Frequently Asked Questions About Hearing and Cognitive Health
Q: Can hearing aids reverse or cure dementia?
A: Hearing aids are not a cure for dementia or Alzheimer’s disease. However, the WHO guidelines and the increasing amount of supporting research suggest that by addressing hearing loss challenges, you can help reduce the risk of cognitive decline.
Treating hearing difficulties helps lessen the strain on your brain and makes it easier to stay socially engaged, both of which are vital for maintaining cognitive function.
Q: When should I get my hearing checked?
A: Have you noticed yourself asking people to repeat themselves more often? Do you find it harder to follow conversations in noisy restaurants, or have family members started commenting on how loud you have the TV? These can all be early signs of hearing difficulties, making now a good time to have your hearing checked.
As changes to your hearing often develop gradually, it can be easy to adapt without realizing how much you may be missing. Even if you feel your hearing is perfectly fine, a baseline hearing assessment gives you a clear picture of where your hearing is today and provides a valuable reference for monitoring any changes over time.
Q: I also have ringing in my ears. Is that related?
A: Many people with hearing loss challenges also experience tinnitus, which is a ringing or buzzing in the ears. If you think you're experiencing tinnitus, it’s another great reason to book an assessment; at York Hearing Clinic, we offer dedicated tinnitus treatment and management strategies.
