World Alzheimer’s Month: Exploring the Connection Between Hearing and Cognitive Health
Have you ever found yourself nodding along at a family dinner, only to realize later that you can’t quite remember the conversation? Perhaps you’ve noticed that understanding the voices of your grandchildren is becoming more difficult, even when they’re sitting right beside you.
It’s easy to dismiss these moments as being tired or distracted or as simply part of getting older. Yet when you regularly find yourself struggling to follow conversations, especially in noisy environments, your hearing may be trying to tell you something.
This year, there is an important reason to pay closer attention to your hearing: The World Health Organization (WHO) has updated its dementia risk-reduction guidelines to include hearing aids, where clinically appropriate, as an intervention that may be offered as part of strategies to reduce dementia risk.
Understanding the WHO’s New Guidelines on Hearing Health
The connection between hearing and cognitive health is not new. In its 2019 dementia risk-reduction guidance, the WHO recognized hearing loss challenges as an important factor to address as part of supporting healthy aging and reducing dementia risk.
Since then, the guidance has evolved alongside the growing body of research. In its 2026 update, the WHO has gone a step further by including hearing aids, where clinically appropriate, as a key intervention that may help reduce the risk of cognitive decline and dementia.
This reflects a broader recognition of the role hearing care can play in supporting your long-term brain health.
How Untreated Hearing Challenges Affect Your Brain
Imagine your brain as a busy office. When sound signals are clear, each department can focus on its job, but when hearing difficulties make speech muffled or unclear, your brain has to devote more attention to working out what was said. This leaves fewer resources available for other functions, such as memory, focus, and problem-solving.
Researchers believe that this additional effort, known as an increased cognitive load, may be one of the factors contributing to the connection between hearing difficulties and an increased risk of cognitive decline.
Hearing difficulties can also affect how connected you feel to the people and activities around you. When following conversations becomes tiring or frustrating, you may start turning down invitations or avoiding busy environments. Over time, this reduction in social engagement can affect your overall well-being and is also associated with an increased risk of dementia.
Your First Step: A Comprehensive Hearing Assessment
The idea of having your hearing evaluated can feel intimidating, but a hearing assessment is a simple and painless first step toward understanding your hearing health.
During your comprehensive hearing assessment, you’ll have the opportunity to talk openly about what you’ve been experiencing and how your hearing may be affecting your everyday life. Your audiologist will take the time to understand your concerns, assess how well you hear and understand speech, and explain your results to you in clear, easy-to-understand language.
Most importantly, you’ll have the information you need to understand your options and decide what feels right for you.
Taking this first step can give you greater confidence in your hearing and help you stay connected to the people and activities that matter most to you. Contact our team at Holland Hearing Center to get started on your hearing health journey today!
Frequently Asked Questions (FAQs)
Q: What are the first signs of hearing loss challenges I should look for?
A: Early signs can be subtle; you might find yourself frequently asking people to repeat themselves or feeling that others are mumbling. Difficulty hearing in noisy environments like restaurants is another classic sign.
Other indicators include needing to turn up the TV volume louder than others prefer or struggling to follow conversations in a group. You may also notice you have a harder time hearing high-pitched voices, such as those of women and children.
Q: Can hearing aids stop dementia?
A: Hearing aids are not a cure for Alzheimer’s or dementia. However, by addressing your hearing difficulties, you reduce the cognitive load on your brain and make it easier to stay socially engaged. Both of these factors are known to support better brain health and may help slow the progression of cognitive decline.
Q: How often should I have my hearing checked?
A: How frequently you should have your hearing checked can vary based on factors such as your age, hearing history, general health, and how often you are exposed to loud sounds.
Having an initial hearing assessment gives you a baseline to refer back to, while future assessments can help track any gradual changes over time. It’s also important to seek an appointment sooner if you notice a sudden change in your hearing, a significant difference between your ears, or new symptoms, such as tinnitus.
