While many people consider hearing loss a normal part of aging, it has shown strong links to brain health regardless of the person’s age. Hearing loss has been attributed to cognitive decline for many people, resulting in memory, focus, and thinking errors.
Here, we will explore how hearing and brain function are connected, as well as what people can do to protect both their hearing and their minds.
What Is Cognitive Decline?
Cognitive decline is when a person has a decreased ability for certain mental functions. This might include problems with:
- Memory
- Learning new things
- Problem-solving
- Paying attention
- Making decisions
Symptoms can be mild, like forgetting where you parked at the grocery store or where you left your car keys, or they can be more serious and result in Alzheimer’s or dementia.
As people age, some changes in brain function are normal. But when these changes happen quickly or affect daily life, it becomes a serious health concern.
How Hearing Loss Affects the Brain
Whether we realize it or not, our brain and ears function as a team. Ears pick up the noise and send it to the brain to help identify what it is and what it means. As hearing declines, the brain has to work harder to fill in the gaps. This extra effort can result in health problems.
Here are three main ways hearing loss may lead to cognitive decline:
Increased Mental Load
When people struggle to hear, the brain uses more energy to try and understand speech. This can lead to what is known as cognitive overload. The issue is that while the brain is expending so much energy to understand speech, other brain functions like storing new memories or learning new tasks become more difficult.
Social Isolation
With hearing loss, many people find it difficult to join in conversations or engage in social gatherings. This can lead them to self-isolate and stop going to those functions or engaging in conversations. As a result, they can experience loneliness, which has been linked to a higher risk of dementia.
Brain Shrinkage
Some studies have shown that hearing loss can result in faster brain shrinkage in the portions of the brain that process sound and speech. This lost brain tissue can impact the ability to store memories and a person’s thinking ability.
What the Research Says
There have been several studies providing a strong link between hearing loss and cognitive decline:
- One study showed that older adults with hearing loss were more likely to develop dementia than those with normal hearing.
- People with moderate hearing loss had three times the risk of dementia.
- Those with severe hearing loss had up to five times the risk.
While this information might be sobering, the important thing is that help is available. By treating hearing loss, people can help protect their brains.
Hearing and Brain Health
Here are steps you can take to care for your hearing and support cognitive health:
Get Your Hearing Checked
Just like vision or dental care, hearing should be tested, especially for adults over age 50. Early detection is key.
Use Hearing Aids When Necessary
It is important to use hearing aids if a hearing health professional has recommended them. This will help you to hear and to engage in conversations, which improves brain function. Those who use their hearing aids are able to:
- Stay more social
- Feel more confident
- Score better on memory tests
Stay Mentally Active
It is important to not stop doing the things you once enjoyed because of hearing loss. Keep your mind active by reading books, doing puzzles or word games, listening to music, or learning a new skill.
Stay Social
Do not remove yourself from social circles. Make sure to stay engaged with friends and family. To help widen your social interactions, consider:
- Joining a club or class
- Calling or visiting friends and family
- Volunteering in your community
If hearing loss makes this hard, ask your doctor about tools like captioned phones or communication apps.
Eat and Sleep Well
To improve brain health, the brain needs fuel. This includes a balanced diet and getting enough sleep so the body and brain can work in concert more efficiently.
Final Thoughts
Recognizing that the brain and hearing are so closely connected is the first step to a better quality of life. As hearing declines, the brain has to work harder, leading to cognitive decline. While the risks are real, the solutions are, too.
Having your hearing tested is so important to protecting your brain. Consulting with hearing health professionals to determine if hearing aids or other technologies can curb the hearing loss is essential.
If you or someone you care about is noticing signs of hearing loss or memory trouble, don’t wait. Talk to a healthcare provider. Early action can make a big difference in living a full, connected, and mentally sharp life.
