Since everything in the body is connected, hearing health also impacts other areas, including your memory and thinking skills. Keep reading to learn how untreated hearing loss could affect your mental health.

Is There a Link Between Hearing Loss and Cognitive Decline?

To put it simply, yes. Research shows a clear link between hearing loss and cognitive decline, which can impact thinking, memory, and problem-solving abilities.

Here’s the good news: hearing loss doesn’t automatically lead to cognitive decline. There are steps you can take to improve your hearing health and protect your brain from the effects of hearing loss. The more you care for your hearing, the better your cognitive function can be.

Are Dementia and Cognitive Decline the Same?

Cognitive decline and dementia are similar, but they aren’t exactly the same. Symptoms of cognitive decline can be mild and often happen naturally with age. It could be something as simple as forgetting a neighbor’s name or misplacing your keys.

Dementia involves more severe memory and thinking problems that make daily life difficult. Symptoms include severe memory loss, the inability to concentrate, poor judgment, and personality or mood changes.

So, can hearing loss cause dementia? The short answer is not directly, but there is a strong link between hearing loss and dementia.

The worse your hearing loss is, the higher your risk might be. Some experts believe that those with mild hearing loss increase their risk by 50%. With moderate to severe hearing loss, that number goes up to 60%.

3 Ways Hearing Loss Accelerates Cognitive Decline

There are three major ways that hearing loss can impact cognitive function:

Cognitive load: When you can’t hear well, your brain has to work extra hard to understand what people are saying. This takes energy away from other brain tasks, such as memory and thinking. Imagine trying to do a crossword puzzle while also trying to remember a grocery list. It’s hard to do both well!
Brain structure changes: Hearing loss can change parts of your brain over time. Just like a muscle, when you don’t use parts of your brain, they can become weaker.
Social isolation: When hearing becomes difficult, it’s normal to start avoiding social activities, such as family gatherings or meeting friends. Although this is a natural reaction to a stressful situation, we need social connections to help keep our brains active and healthy.

Recognizing the Signs: When to Seek Help

Seeking help as soon as you notice certain signs is the best way to protect yourself from the negative effects of hearing loss. Here are some signs of hearing issues:

Asking people to repeat themselves often
Finding it hard to follow conversations in noisy places
Turning up the TV or radio volume higher than before
Trouble hearing on the phone
Family members notice you don’t respond when they talk to you
Feeling confused during conversations
Avoiding social activities you used to enjoy
Finding it harder to remember things right after hearing them

How to Protect Your Brain: Treating Hearing Loss

If you’re dealing with hearing loss, you’re not alone! Here are some steps you can take to protect your brain from the effects of hearing loss and prevent it from negatively impacting your everyday life.

Get fitted for hearing aids to help make sounds louder and clearer.
Invest in assistive listening devices designed for specific situations, like watching TV.
Check to see if you’re eligible to receive a caption phone from ClearCaptions at no cost to you to make phone conversations easier to understand.

The key is to get help early. The longer you wait to treat hearing loss, the harder it can be for your brain to adjust.

Preventive Steps and What You Can Do

You don’t have to wait until you’re experiencing hearing loss to protect your hearing health. Here are some steps you can take now:

Protect your ears: Avoid very loud noises or wear ear protection when doing things like mowing the lawn or attending a concert.
Get regular hearing checks: Just as you check your blood pressure, your hearing should be checked regularly after the age of 60.
Stay socially active: Stay connected with friends and family, join clubs, or volunteer to keep your brain engaged and stimulated.
Exercise your brain: Do puzzles, read, learn new skills, or play games that make you think.
Manage health conditions: Control problems like high blood pressure and diabetes, which can affect both hearing and brain health.
Eat well: A heart-healthy diet rich in vegetables, fruits, and whole grains supports your ears and brain.

Taking care of your hearing is an important part of keeping your body and mind happy and healthy. If you’ve noticed changes in your hearing, don’t wait to get help. Your brain will thank you!

Frequently Asked Questions

Can hearing loss cause dementia?

Hearing loss doesn’t directly cause dementia, but it can increase your risk. When you can’t hear well, it can lead to your brain working harder, social isolation, and may cause changes in brain structure. All of this stress on your brain increases your risk of developing dementia.

Do hearing aids really help prevent cognitive decline?

Some studies have suggested that wearing hearing aids can help slow cognitive decline. Hearing aids help your brain process certain noises and sounds, reducing the extra work your brain has to do when you have hearing issues. When it’s easier for you to hear, you’re also more likely to stay connected with your friends and family, which is also important for brain health. While hearing aids can’t guarantee you won’t have memory problems, they’re an important tool for keeping your brain healthy as you age.
