Quick Summary: Hearing loss becomes increasingly common with age, but its effects may extend beyond everyday communication. This guide from Jewish Community Housing Corporation (JCHC) uncovers the link between dementia and hearing loss, why hearing changes may affect memory and thinking, and whether hearing aids can help support cognitive health. It also covers signs of hearing loss in seniors and practical ways families can make communication easier.
Maybe your parent has started turning the television up louder. They ask you to repeat yourself more often, have trouble following conversations at family gatherings, or seem to withdraw when several people are talking at once.
Because hearing loss is so common, it can be easy to dismiss it as simply part of getting older. But its effects may go beyond turning up the television or asking someone to repeat themselves. Research has also found a connection between hearing loss and cognitive decline, including changes in memory, attention, and other thinking skills.
At Jewish Community Housing Corporation (JCHC), we know that healthy aging involves looking at the whole person. Understanding how hearing, social connection, and cognitive health may be related can help older adults and families make more informed decisions about their well-being.
Is There a Connection Between Hearing Loss and Dementia?
Yes. Research has found a clear connection between dementia and hearing loss, but that does not mean hearing loss directly causes dementia.
The 2024 Lancet Commission on dementia prevention noted hearing loss as one of 14 risk factors for dementia that may be possible to address or manage. The Commission also estimated that around 7% of dementia cases at a population level were associated with hearing loss.
That number may sound alarming; however, it is important to put it in perspective. Treating hearing loss will not automatically prevent 7% of dementia cases, nor does it mean that someone with hearing loss will develop dementia.
What the research tells us is simpler: hearing health and brain health appear to be connected. A recent scientific review published in Frontiers on Dementia also notes that hearing loss is associated with a higher risk of cognitive decline and dementia, but researchers are still working to understand exactly why that relationship exists.
Why Is Hearing Loss Linked to Cognitive Decline?
Researchers are still studying exactly why hearing and brain health appear to be connected. There may be several factors involved.
The Brain Has to Work Harder to Listen
When sounds are unclear, the brain has to put more effort into understanding speech. Researchers sometimes call this cognitive load. Put simply, more mental energy is being used just to follow what someone is saying, which may leave fewer resources available for memory and thinking.
Hearing Loss Can Make Socializing Harder
Imagine trying to follow a family dinner when you can hear only parts of every conversation. Over time, someone may begin avoiding gatherings, restaurants, activities, or visits with friends because listening feels frustrating or exhausting.
Johns Hopkins Medicine notes that hearing loss can contribute to this kind of withdrawal, and social isolation itself has also been associated with poorer cognitive health and a higher risk of dementia.
The Brain May Receive Less Stimulation
Hearing does more than help us follow conversations. Sounds from people, music, television, nature, and everyday surroundings continually give the brain information to process. When hearing loss reduces that input, parts of the brain involved in processing sound may receive less stimulation over time, explained Dr. Dylan Wint, MD, of the Cleveland Clinic in a conversation on the connection between hearing loss and dementia.
“When you lose auditory input, when you lose sound, you’re not just depriving your ears of sound, you’re depriving your brain, specifically your auditory cortex, the area that’s responsible for processing sounds into meanings. The auditory cortex is linked to language and memory networks in the brain,” Wint said.
Researchers are studying whether these changes may help explain the connection between hearing loss and cognitive decline.
Signs of Hearing Loss in Seniors to Watch For
Age-related hearing loss usually develops gradually, which means your loved one may not immediately recognize that their hearing has changed.
Common signs can include:
- Frequently asking people to repeat themselves
- Turning the television or radio louder than others prefer
- Struggling to follow conversations in groups or noisy places
- Thinking people sound like they’re mumbling
- Missing phone calls, doorbells, alarms, or other sounds
- Becoming quieter or avoiding conversations and social gatherings
These changes do not mean your loved one has dementia. They may simply be signs that it is time to have their hearing checked.
Can Hearing Aids Help Protect Cognitive Health?
Research findings are promising, but it’s too early to say whether hearing aids prevent dementia.
One of the strongest studies so far is the NIH-funded ACHIEVE trial, which followed 977 adults ages 70-84 with untreated hearing loss for three years. When researchers examined everyone in the study together, hearing intervention did not significantly slow cognitive decline compared with a health-education program.
However, among participants who entered the study with more risk factors for cognitive decline, those receiving the hearing intervention experienced an almost 50% slower rate of cognitive decline over three years.
These results are encouraging, but we still don’t have definitive proof that hearing aids can prevent dementia. Researchers are continuing to follow participants to better understand the long-term effects of treating hearing loss on brain health.
What we do know is that addressing hearing loss can make communication easier and can help older adults stay more involved in conversations and daily life.
What Can Seniors and Families Do About Hearing Loss?
If you notice hearing changes in yourself or someone you love, addressing them early can make communication easier and help clarify whether certain behaviors are related to hearing or memory.
1. Get Their Hearing Checked
Hearing loss in seniors is common, but it shouldn’t be ignored. A primary care provider or audiologist, a healthcare professional specializing in hearing, can evaluate hearing loss and recommend appropriate support, including hearing aids when needed.
2. Make Sure They Heard You
This is especially important when families are also concerned about memory.
If you tell your father about an appointment from across the room and he later says he doesn’t remember it, consider whether he clearly heard the conversation in the first place. Get his attention, face him when speaking, reduce background noise, and confirm that he understood what was said.
These small changes can help families distinguish between difficulty hearing information and difficulty remembering it.
3. Make Conversations Easier
Shouting isn’t necessarily the best way to help. Instead, speak clearly and naturally, face the person so they can see your expressions, and avoid talking from another room.
At family gatherings, turn down background music or the television and choose a quieter place for conversation. If several people are talking at once, slowing things down and taking turns can make it much easier for your loved one to participate.
4. Notice Social Changes
Sometimes hearing loss shows up in someone’s behavior before they talk about their hearing.
A parent who once enjoyed family dinners may start sitting quietly. Someone who loved going out may begin declining invitations. They may appear uninterested when, in reality, keeping up with conversation has simply become exhausting.
Rather than assuming they no longer want to socialize, ask what would make these situations more comfortable. A smaller gathering, quieter restaurant, or one-on-one conversation may help them stay connected.
5. Give Your Loved One Time to Adjust
If hearing aids are recommended, adjusting to them may take time. Encourage your loved one to work with their hearing professional if they’re uncomfortable or aren’t helping as expected.
One change shouldn’t wait: Sudden or rapidly worsening hearing loss isn’t a normal part of aging. The National Institute on Deafness and Other Communication Disorders(NIDCD) considers sudden hearing loss a medical emergency and recommends seeking medical attention promptly.
Supporting Cognitive Wellness and Connection at JCHC
Hearing changes, memory concerns, and the changes that often come with aging can sometimes make a person’s world feel smaller. Conversations may become harder to follow, social gatherings may feel tiring, and families may begin wondering what kind of support would help without taking away the independence their loved one values.
At JCHC’s Lester Senior Living in Whippany, New Jersey, care is shaped around the individual. Whether someone lives independently, needs some assistance, or requires memory care, the goal is to provide the right level of support while respecting their autonomy, dignity, routines, and personal choices.
Connection is an important part of that experience, too. Residents can choose from opportunities such as fitness and art classes, games, lifelong learning, cultural outings, religious services, and intergenerational programs. Residents aren’t expected to participate in everything. Instead, residents can decide what feels right for them while having regular opportunities to share conversations, build friendships, and remain part of a community. For someone who has begun withdrawing because of hearing or cognitive changes, those everyday moments of connection can be especially meaningful.
If you’re noticing changes in your loved one’s hearing, memory, or ability to stay connected, you don’t need to figure out everything on their own. Talk with their healthcare providers, ask questions, and take time to understand what they may need. And if you’re beginning to explore senior living or memory care, schedule a visit to Lester Senior Living. Our friendly, warm community may be the right fit and help your loved one feel like they’re being heard.
Frequently Asked Questions
Q: Does hearing loss cause dementia?
A: Hearing loss does not necessarily cause dementia, according to current research.
Many people with hearing loss never develop dementia, and many people with dementia do not have significant hearing loss. It is more accurate to think of hearing loss as one factor that may be linked to a higher risk of cognitive decline.
This distinction can be especially helpful for families. Sometimes an older adult may seem forgetful, distracted, or confused simply because they did not hear the full question or conversation. The National Institute on Aging notes that hearing problems can sometimes make an older adult appear confused or unresponsive when hearing loss may actually be the root cause.
Q: Can wearing hearing aids prevent dementia?
A: Research is promising, but hearing aids have not been proven to prevent dementia. Studies suggest that treating hearing loss may help support cognitive health in some older adults while also making it easier to communicate and stay socially connected.
Q: Can hearing loss be mistaken for dementia?
A: Sometimes, families may mistake hearing loss for dementia. An older adult who doesn’t hear a question or conversation clearly may appear forgetful, confused, or unresponsive. If you notice changes in both hearing and memory, consider having their hearing evaluated and discussing cognitive concerns separately with their healthcare provider.
Q: Is JCHC Open to All Seniors?
A: Yes! JCHC is open to seniors of all faiths, cultures, and backgrounds. Residents do not need to be Jewish to call JCHC home, and everyone is welcomed as a valued part of the community.
