Hearing changes are common as people grow older, but they should not be ignored. Many seniors slowly adjust to hearing difficulties without realising how much it can affect daily communication, confidence, social connection, and overall wellbeing. In recent years, research has shown an association between untreated hearing loss and dementia risk. This does not mean hearing loss directly causes dementia. However, studies suggest that hearing loss in older adults may be linked with cognitive decline, reduced brain stimulation, increased listening effort, and social withdrawal. Because of this, early hearing checks are an important step in supporting healthy ageing. At Welfast Hearing, we provide professional hearing care and hearing tests for seniors across Bateau Bay, Morisset, Central Mangrove, and Woongarrah, helping older adults understand their hearing and take timely action.
What Is Age-Related Hearing Loss?
Age-related hearing loss, also known as presbycusis, is a gradual reduction in hearing that
happens as people get older. It often affects both ears and may develop slowly over many
years. Because the change is gradual, many older adults may not notice the early signs
immediately.
According to the National Institute on Deafness and Other Communication Disorders,
age-related hearing loss is one of the most common conditions affecting older adults, and
nearly half of people over 75 experience difficulty hearing.
Older adults may benefit from a hearing test if they notice:
Difficulty Following Conversations
Many seniors find it harder to follow conversations, especially when more than one person is
speaking.
Trouble Hearing in Background Noise
Restaurants, family gatherings, community events, and busy public spaces can become
challenging.
Frequently Asking People to Repeat Themselves
Repeatedly asking “What?” or “Can you say that again?” may be an early sign of hearing
difficulty.
Turning the TV or Phone Volume Up
Family members may notice the television or phone volume is louder than usual.
Avoiding Social Situations
Some older adults may withdraw from conversations because listening feels tiring or
frustrating.
Can Untreated Hearing Loss Affect Memory and
Thinking?
Research has found that hearing loss is associated with a higher risk of cognitive decline
and dementia in older adults. However, it is important to use careful medical wording:
hearing loss should not be described as a direct cause of dementia.
A Johns Hopkins study reported that older adults with greater severity of hearing loss were
more likely to have dementia, while dementia likelihood was lower among hearing aid users
compared with non-users.
Why the Link Between Hearing Loss and Cognitive Decline Matters
When hearing becomes difficult, the brain may need to work harder to understand speech.
This increased listening effort can make conversations mentally exhausting. Over time,
some researchers believe this may contribute to reduced cognitive reserve, lower social
engagement, and changes in how the brain processes sound.
A narrative review from Johns Hopkins explains that possible pathways linking hearing loss
and dementia include greater cognitive load, changes in brain structure and function, and
decreased social engagement.
How Reduced Sound Input May Affect Brain
Stimulation
Hearing is not only about the ears. The brain plays a major role in processing sound,
understanding speech, recognising voices, and interpreting the environment
When hearing loss is left untreated, the brain receives less clear sound information. This can
make listening more demanding, especially in noisy places or group conversations.
The Brain May Work Harder to Fill in the Gaps
When speech sounds are unclear, the brain may need to guess missing words or rely
heavily on context. This can make everyday communication tiring.
Example
A senior may hear parts of a sentence but miss important words. Instead of naturally
following the conversation, they may need to focus intensely, guess meaning, and ask for
repetition.
Over Time, This Can Affect Confidence
When conversations become difficult, some older adults may feel embarrassed, frustrated,
or less confident in social settings.
This Is Why Early Hearing Support Matters
A hearing test can identify hearing changes early and help seniors receive the right advice
before communication difficulties become more limiting.
Untreated Hearing Loss and Social Isolation
One of the most important concerns linked to untreated hearing loss is social withdrawal.
Seniors who struggle to hear may avoid phone calls, family events, community gatherings,
religious meetings, or group conversations.
How Hearing Loss Can Lead to Isolation
Hearing loss may cause older adults to:
- Avoid conversations because they are difficult to follow.
- Feel left out during family discussions and group conversations.
- Stop attending social events and community gatherings.
- Become less active in community life and daily activities.
- Feel frustrated or embarrassed when frequently asking others to repeat themselves.
Social connection is important for emotional wellbeing and healthy ageing. When hearing
loss makes communication difficult, it can affect both confidence and quality of life
Why Early Hearing Tests Are Important for Seniors
A hearing test is a simple and important step for older adults who notice changes in
hearing, communication, or listening comfort. It helps identify the type and level of hearing
loss and provides clear guidance on suitable next steps.
Benefits of a Hearing Test for Seniors
A senior hearing test can help:
- Detect hearing loss early.
- Understand whether hearing changes are mild, moderate, or more significant.
- Identify whether one or both ears are affected.
- Support better communication with family and friends.
- Guide hearing aid recommendations where suitable.
- Improve confidence in everyday listening situations.
When Should Seniors Book a Hearing Test?
Seniors should consider booking a hearing test if they:
- Struggle to hear speech clearly.
- Have difficulty hearing in noisy environments.
- Turn up the TV volume often.
- Miss doorbells, phone calls, or alarms.
- Feel tired after conversations.
- Avoid social situations due to hearing difficulties.
- Experience ringing or buzzing sounds in the ears (tinnitus).
When Hearing Aids May Support Communication
and Daily Confidence
Hearing aids do not cure dementia and should not be promoted as a guaranteed way to
prevent cognitive decline. However, for many people with hearing loss, hearing aids may
improve access to sound, support clearer communication, and reduce listening strain.
A 2024 cohort study published in JAMA Otolaryngology–Head & Neck Surgery found that
hearing loss was associated with increased dementia risk, particularly among people not
using hearing aids, while also noting the need for more high-quality long-term studies.
How Hearing Aids May Help Older Adults
When professionally fitted and adjusted, hearing aids may help seniors:
- Hear conversations more clearly.
- Participate more comfortably in family life.
- Feel more confident in social settings.
- Reduce the effort needed to follow speech.
- Stay more connected with people and activities.
- Improve day-to-day communication.
Hearing Support Should Be Personalised
Every person’s hearing needs are different. Some seniors may need hearing aids, while
others may need monitoring, ear wax management, tinnitus support, or communication
advice. A professional hearing test helps identify the most suitable path.

FAQs .
Can untreated hearing loss cause dementia?
Untreated hearing loss should not be described as directly causing dementia. However,
research has found an association between hearing loss and increased dementia risk in
older adults. The relationship may involve factors such as increased listening effort, reduced
sound input, and social isolation.
Does hearing loss affect memory?
Hearing loss may affect how easily a person follows conversations and processes spoken
information. When listening becomes difficult, the brain may need to work harder to
understand speech, which can make communication more tiring.
Are hearing tests important for seniors?
Yes. A hearing test for seniors can help detect hearing loss early and guide the right support.
Early hearing care may help improve communication, confidence, and daily quality of life.
Can hearing aids prevent dementia?
Hearing aids should not be promoted as a guaranteed way to prevent dementia. However,
they may support clearer communication and reduce listening difficulty for people with
hearing loss. Some studies suggest hearing aid use may be linked with lower dementia risk,
but more research is still needed.
What are the early signs of age-related hearing loss?
Early signs include difficulty hearing conversations, trouble hearing in background noise,
asking people to repeat themselves, increasing TV volume, missing phone calls, and
avoiding social situations.
