Quick Answer
Research shows a link between hearing loss and dementia risk, but the evidence is still developing and hearing aids are not proven to prevent dementia. What is well established is that treating hearing loss helps you stay connected, engaged and communicating well, which supports healthy ageing in general. If you’re concerned about your hearing, a hearing test is a sensible place to start.
There has been a lot of coverage in the news about the link between hearing loss and dementia, and it’s a subject we get asked about often. Trevor Chapman, Lead Audiologist at angli-EAR Hearing, has spent over 22 years helping people hear better, and here he sets out what the evidence currently says, and just as importantly, what it doesn’t say.
What is dementia?
Dementia describes a group of symptoms, including memory loss and difficulty with thinking, problem solving or language, that build up gradually over time. It mainly affects people over 65, though it isn’t an inevitable part of ageing. The early changes are often small and easy to miss, but dementia is progressive and can eventually affect daily life quite significantly. If you or someone close to you is noticing these kinds of changes, the first step is booking an appointment with your GP.
Is there a link between hearing loss and dementia?
Yes, researchers have found an association between hearing loss and a higher risk of dementia, though exactly how the two are connected isn’t fully understood yet. The World Health Organisation’s 2026 guidelines list hearing loss among a number of factors that may be linked to cognitive decline. One possible explanation is that when hearing takes more effort, the brain has to work harder to fill in the gaps, and this extra strain may affect brain health over time. There’s a social side to it too. When conversations become tiring or hard to follow, it’s common to withdraw from social situations, and social isolation is itself linked to a higher dementia risk.
Do hearing aids reduce the risk of dementia?
Here it’s worth being honest about what the evidence can and can’t tell us. The WHO’s own guidance rates the evidence behind hearing aids and dementia risk as low certainty, meaning the true effect could turn out to be quite different from early estimates, and it stops short of saying hearing aids prevent dementia. In 2026 the British Society of Audiology, British Academy of Audiology and British Society of Hearing Aid Audiologists issued a joint statement making the same point clearly: hearing aids may have some role in supporting brain health, but they shouldn’t be presented as a guaranteed way to reduce dementia risk, and that association shouldn’t be used to persuade people into buying hearing aids.
What we can say with confidence is that hearing aids help with things we can measure and feel the benefit of every day. If you’re not sure whether your hearing needs attention, our FREE Hearing Screening is a straightforward, no-pressure way to find out where you stand.
What are the proven benefits of treating hearing loss?
Whatever the dementia research eventually settles on, treating hearing loss brings benefits that are already well established and easy to notice day to day, including:
- Easier, less tiring conversations
- More confidence in social situations
- Staying involved in the things you enjoy, rather than sitting them out
- Reduced listening effort
- A general improvement in quality of life
These benefits matter in their own right. They also support the kind of active, connected life that’s generally good for brain health, whatever role hearing loss specifically turns out to play in dementia risk.
How is hearing loss treated?
Treatment depends on the cause and severity of your hearing loss. Options include:
- Earwax removal. Earwax blockage is a common and reversible cause of hearing loss, which an audiologist can remove by flushing, scooping or suctioning.
- Hearing aids. If your hearing loss is due to damage in the middle or inner ear, a hearing aid can make sounds stronger and clearer. An audiologist can talk through the options with you, recommend a device, and fit it properly.
- Implantable devices. Depending on the cause of your hearing loss, options such as cochlear implants, middle ear implants, auditory brainstem implants or bone-anchored hearing aids may be suitable. Your audiologist can work alongside an ENT specialist to discuss the risks and benefits.
- Surgical procedures. Surgery may be needed after a traumatic ear injury, or for repeated infections that require small tubes to help the ear drain.
Our 30-day no-obligation hearing aid trial lets you experience the benefits for yourself before committing to anything.
What should I do if I think I have hearing loss?
If you’re noticing memory or thinking changes alongside hearing concerns, start with your GP, who can look at the fuller picture. The Alzheimer’s Society also has a helpful symptoms checklist if that would help you prepare for the conversation.
For your hearing itself, you’re welcome to come to us directly. Book a FREE Ear Health Check or FREE Hearing Screening and we’ll give you clear, honest information about your hearing and the options available, and we’re happy to share the results with your GP if that’s useful for you.
Frequently Asked Questions
Do hearing aids prevent dementia?
No. Current evidence suggests hearing aids may play some role in supporting brain health, but they are not proven to prevent dementia, and no audiologist should suggest otherwise.
Is hearing loss a direct cause of dementia?
Researchers have found an association between the two, but a direct causal link hasn’t been established. Dementia risk depends on a wide range of factors, of which hearing is just one.
Should I get a hearing test if I’m worried about dementia?
It’s a sensible step either way. Even without any dementia concerns, treating hearing loss brings real, measurable benefits for communication and day-to-day quality of life.
What is Dementia Action Week?
Dementia Action Week is a national awareness campaign led by the Alzheimer’s Society, held every May, encouraging people to act early on memory and thinking concerns.
