Can Hearing Aids Help Reduce Dementia Risk?
Aarti Raicha • May 24, 2025
It starts subtly. You’re in a crowded café, and you miss the punchline of a joke. You smile anyway, pretending you heard it. At dinner, you ask someone to repeat themselves for the third time. Even though you turn the TV volume as high as it goes, you notice it still sounds muffled, almost like you're wearing headphones. You tell yourself it’s nothing serious—just a bit of background noise, maybe some tired ears. But in the back of your mind, there’s a whisper: “What if it’s more?”
If you’re starting to notice these signs, you’re not alone. Hearing loss affects millions of people, especially as we get older. But what many people don’t realise is how closely hearing is tied to brain health. Researchers are now uncovering a powerful link between untreated hearing loss and dementia. The question is—can using hearing aids make a difference? The simple answer is yes. Let's examine how and why.
The Link Between Hearing and the Brain
Although your brain isn't responsible for hearing, it processes, remembers and understands all sounds the ear sends. But when the ear starts struggling with its duty and sends scrambled signals, it makes your brain work harder to interpret these sounds. Have you ever tried having a conversation at a party with the music blaring and, to top it off, the other person is whispering? That frustration you feel, yes, that's what your brain feels when you have untreated hearing loss.
Over time, this extra effort piles up (because your brain is running extra shifts it isn't built for). The longer this goes on, the harder it is to remember things and concentrate, which in turn affects your social connections.. You might find yourself withdrawing from conversations, avoiding social situations, and feeling more isolated. It’s not just a feeling—studies have shown that social isolation, often caused by hearing loss, is a major risk factor for dementia.
However, there’s another reason hearing matters so much: when the brain doesn’t get regular stimulation from sound, it begins to change. Areas that once processed sound start to shrink. Connections weaken. Memory suffers. This process is slow, but it’s real—and it’s one reason why hearing loss is now considered the number one modifiable risk factor for dementia.
So, Where Do Hearing Aids Come In?
If hearing loss increases your risk of dementia, then treating it might reduce that risk. That’s exactly what researchers have been looking into—and the findings are hopeful.
A major study published in 2023 found that people at risk of dementia who wore hearing aids had slower cognitive decline than those who didn’t. Other studies suggest that people who use hearing aids stay more socially engaged and mentally active, two important ways to protect the brain as we age.
When you wear hearing aids, you’re not just making sounds louder—you’re giving your brain the information it needs to stay sharp. Conversations become easier. You start picking up on little sounds again—the birds outside, the kettle boiling, the soft rustle of leaves. These sounds keep your brain active. They help you stay present.
And when you feel more confident hearing and engaging with others, you’re more likely to take part in life—to laugh, listen, share stories, and keep your mind busy. These small everyday moments are what protect memory and slow decline.
Early Action Makes the Biggest Difference
The key is not to wait.
Many people put off getting hearing aids, sometimes for years. Maybe it’s the stigma. Maybe it’s denial. But the longer hearing loss goes untreated, the harder it becomes for your brain to adjust. Those pathways that once processed sound grow quiet, and it takes more effort to wake them up again.
Getting help early means your brain doesn’t lose those connections. It means adapting more easily to hearing aids. And it means giving yourself the best chance to stay sharp, social, and independent.
You don’t need to wait until your hearing is “bad enough.” If you’ve noticed changes—struggling to follow conversations, avoiding noisy environments, feeling tired from listening—then it’s time to get a hearing test. It’s quick. It’s painless. And it could make more of a difference than you think.

According to a 2023 review published in the British Journal of General Practice , roughly 2.3 million people in the UK need professional treatment for troublesome earwax every year, making it one of the most common reasons people see a GP about their ears. Despite how common it is, a lot of people still imagine the same scene when they think about having their ears cleaned, a large metal syringe, a tilted head over a bowl, a few uncomfortable minutes, and that picture is years out of date at most reputable clinics now. If “ear syringing near me” is the search that brought you here, here’s what’s actually changed, and why. Why syringing fell out of favour That same British Journal of General Practice review notes that manual water-filled syringes are no longer recommended in the UK, largely because of the risk of damage to hearing and the legal exposure that came with it. The old method relied on a clinician judging water pressure by hand, which left very little margin for error in a part of the body as delicate as the ear canal. Even the controlled, electronic irrigation that replaced it carries a real complication rate. A study published in BJGP Open put the risk of an ear infection called otitis externa following irrigation at around 3 per cent, which sounds modest until it’s scaled up. Across England and Wales, that works out to roughly 69,000 additional cases a year. None of this makes irrigation dangerous in the way the old manual method could be, but it does explain why so many clinics, ours included, have shifted toward an approach with a lower risk profile altogether. What’s actually recommended now NICE , the body that sets clinical guidance across the NHS, recognises three accepted methods for clearing earwax: electronic irrigation, microsuction, and manual removal using small instruments. Its guidance also rules irrigation out for some patients, including those with a history of a perforated eardrum, a current ear infection, or only one working ear. That’s a real shift from the old assumption that syringing was a one-size-fits-all fix for anyone with blocked ears. Whether the right method for you is microsuction, irrigation, or something else depends on your own ear history, and a proper look inside the canal first is what actually determines that, not which service happens to be advertised. Why microsuction has become the default At Ealing Hearing Centre, microsuction is our standard approach, and the reason comes down to control. The clinician can see the ear canal under magnification for the entire procedure, using gentle suction rather than water, so there’s no flushing and no pressure against the eardrum. It also sidesteps most of the reasons irrigation gets ruled out, which is part of why it’s become the preferred option for ear wax removal in London and well beyond it, not just within private practice. For most people, the whole procedure takes around twenty minutes, and the change in hearing is immediate once the blockage clears. So is “ear syringing” still a thing? In everyday language, the term has stuck around even though the original method largely hasn’t. Call most clinics today and ask for ear syringing, and what you’ll actually be offered is either electronic irrigation or microsuction, assessed against your ear history first rather than handed out by default. Whether you’d call it ear syringing, ear cleaning, or professional ear cleaning, the underlying decision is the same one: what’s actually in the canal, and which method suits it. Anywhere still offering the old hand-syringe method without checking your history first is worth being cautious of, given what the evidence now says about it. Getting it looked at properly Whichever approach ends up being right for your ears, that’s a decision worth making after an otoscopic examination, not before one. At Ealing Hearing Centre, we examine the ear canal before recommending anything, and where professional ear cleaning or ear wax removal in Ealing, Stanmore, or the wider London area turns out to be the right next step, it can usually be arranged the same day.

A 2023 review in the British Journal of General Practice notes that earwax build-up can happen to anyone, but it shows up more often in older adults and in people who wear hearing aids or earbuds regularly, with around 2.3 million people across the UK needing professional help for troublesome earwax in a given year. For hearing aid users specifically, that build-up doesn’t always behave the way it does for everyone else, and it’s worth understanding the difference before assuming a device has simply stopped working properly. Why hearing aids change how earwax behaves Earwax normally makes its own way out of the ear canal, helped along by jaw movement and the slow outward migration of skin cells. A hearing aid dome, mould, or receiver sitting inside that canal gets in the way of that process, partly by physically blocking the path wax would otherwise take, and partly because the ear can respond to anything sitting inside it by producing more wax than usual. Devices that place more hardware directly in the canal, such as receiver-in-canal models or custom moulds, tend to be affected by this more than behind-the-ear styles with a more open fit. Signs it’s the wax, not the device A lot of people spend weeks troubleshooting a hearing aid before considering that earwax might be the actual cause. A few signs worth paying attention to: Whistling or feedback that wasn’t there before, even at the usual volume Sound that feels muffled or distant despite fresh batteries or a full charge A dome or mould that suddenly feels tighter or less comfortable than it used to Itching or a sense of fullness around where the device sits in the ear None of these confirm earwax on their own, since hearing aid components can fail for other reasons too, but they’re a reasonable prompt to get the ear looked at properly before adjusting settings or replacing parts. Why this needs a proper look rather than a home fix Cotton buds are a bad idea for anyone, but they’re a particular risk for hearing aid users, since the canal already has less space to work with and a bud can push wax further in more quickly than it would otherwise. Softening drops can help with mild build-up, but once wax has compacted against a mould or receiver that’s been blocking its way out for a while, drops alone usually aren’t enough. An otoscopic examination is the only reliable way to tell whether the issue is earwax, debris caught around the device itself, or a genuine hardware fault, and getting that distinction right saves you from troubleshooting the wrong problem for weeks. A routine that keeps things clearer for longer Wiping the device down daily, replacing wax guards on schedule rather than waiting for them to fail, and having the ear canal checked periodically rather than only after a problem develops all make a noticeable difference over time. For patients who find getting to a clinic difficult, mobile earwax removal brings the same otoscopic-led approach to the home, which matters particularly for older hearing aid users, who are also the group most likely to be affected by build-up in the first place. Looking after both together Because Ealing Hearing Centre fits hearing aids and treats earwax build-up under one roof, we can look at both sides of the problem in the same appointment rather than sending you elsewhere for half the picture. If your hearing aids have felt less effective lately, or you’ve been searching for ear wax removal near me without realising the two issues might be connected, it’s worth finding out which one is actually responsible.

According to the RNID , the average person in the UK waits ten years between first noticing symptoms of hearing loss and actually doing something about it. A 2024 analysis published in the International Journal of Audiology , drawing on the most recent UK census data, found that as many as one in three adults aged 18 to 80 has some degree of hearing loss, and most of them have not had it assessed. If you have been putting off a hearing test in London, this article covers what a professional assessment involves, what it can identify, and how to know when it is time to book one. Why people put off hearing tests Hearing loss tends to develop gradually, which makes it easy to adjust to rather than address. The brain compensates over time, filling in gaps in conversation or sound. By the time the problem becomes obvious to other people, it has often been present for years. There is also a common assumption that hearing tests are only for older people, or only necessary once hearing has deteriorated significantly. Neither is accurate. Hearing assessments are useful at any age and often identify issues that are straightforward to address when caught early. What a hearing test actually involves A professional hearing assessment is not a single test. It is a structured process designed to build an accurate picture of how the ears and auditory system are functioning. At a hearing centre in London such as Ealing Hearing Centre, appointments typically include the following: Initial consultation Before any testing begins, the audiologist will ask about your hearing history, any specific symptoms you have noticed, your noise exposure history, and any relevant medical background. This helps place the test results in proper context rather than treating the numbers in isolation. Ear examination The audiologist will examine the ear canal and eardrum using an otoscope. This step is important because a number of common issues, including ear wax build-up, can affect test results or require treatment before accurate testing is possible. Wax in ears symptoms such as muffled hearing or a feeling of fullness can mimic hearing loss, and identifying this early prevents unnecessary concern or misinterpretation. Pure tone audiometry This is the core of most hearing assessments. You will wear headphones and respond to a series of tones played at different frequencies and volumes. The results are plotted on an audiogram, which maps the quietest sounds you can hear across a range of pitches. The pattern this produces tells the audiologist a great deal about the nature and degree of any hearing loss. Speech recognition testing Pure tone results show what you can hear in terms of volume and frequency, but speech recognition testing shows how well the brain processes what it hears. Two people with similar audiograms can have very different experiences of conversation, particularly in noisy environments, and this test helps explain that gap. Tympanometry This measures how well the eardrum and middle ear are functioning by creating small changes in air pressure in the ear canal. It helps identify issues such as fluid behind the eardrum or problems with the middle ear bones, which would not be detected by tone testing alone. What happens after the test Once the assessment is complete, the audiologist will explain the results clearly and in plain terms. If no hearing loss is detected, you will leave with a clear baseline and confidence that things are functioning as they should. If hearing loss is identified, the audiologist will explain its degree and nature, and discuss the options available, whether that means monitoring, treatment, hearing aids, or a referral. If wax build-up is identified during the examination, ear wax removal in Ealing can often be carried out at the same appointment or arranged promptly, removing a potential barrier to accurate results and immediate comfort. When you should actually book a hearing test in London There is no single threshold that makes a hearing test necessary. The following situations are all reasonable reasons to book an assessment: You frequently ask people to repeat themselves, particularly in background noise You find phone calls, television, or group conversations harder to follow than they used to be You have noticed ringing, buzzing, or other sounds in your ears that others cannot hear Someone close to you has commented on your hearing You have a history of significant noise exposure through work or leisure Your hearing feels muffled or blocked and it has not cleared on its own You have not had a hearing test before and want to establish a baseline Hearing tests in Stanmore are available at Ealing Hearing Centre for patients based in and around the Stanmore area, alongside appointments for patients across West London. Why earlier is better The relationship between untreated hearing loss and wider health outcomes is increasingly well documented. Research has identified associations between persistent untreated hearing loss and cognitive decline, social withdrawal, and reduced quality of life. The earlier hearing loss is identified and addressed, the greater the opportunity to manage those downstream effects. There is also a practical dimension. Hearing aids and other interventions work more effectively when fitted earlier, before the auditory pathways have spent years compensating for diminished input. A test that comes back with no concerns is still a useful data point. A test that identifies a problem early gives you options that may not be available later. What if ear wax is the problem rather than hearing loss? Not every hearing difficulty signals permanent loss. Ear wax build-up is one of the most common and most overlooked causes of muffled hearing, and it is entirely reversible. If you have been putting off a hearing test because you suspect wax may be involved, the answer is still to get assessed rather than to wait. For patients who cannot easily travel to a clinic, mobile earwax removal brings professional assessment and treatment directly to the home. The same standard of care applies, with otoscopic examination carried out before any wax removal takes place. Same-day ear wax removal in Stanmore is available for patients in the area who need prompt relief from blocked hearing or discomfort, without having to travel into central London. Book a hearing assessment at Ealing Hearing Centre Ealing Hearing Centre provides hearing tests in London for patients across West London and the surrounding areas, including Stanmore, Ruislip, and Ealing. Appointments include full audiological assessment, otoscopic examination, and clear explanation of results. Where ear wax removal in Ealing is needed as part of the appointment, this can typically be arranged on the same day.
