Hearing Loss and Memory: Insights from the Latest Research
If you or someone you love is experiencing hearing loss or memory difficulties, there is some encouraging news. New research suggests that treating hearing loss may help protect brain health, especially for people at higher risk of dementia.
The Lancet Commission on Dementia Prevention has identified hearing loss as one of the most important risk factors that can be addressed to reduce the risk of dementia. Now, a new NHS-based study is helping to show how supporting hearing could have a real-world impact on brain health.
How Are Hearing and Memory Connected?
Hearing loss and mild cognitive impairment (MCI), a condition that involves early memory and thinking problems, are both common in older adults. Each condition is linked to a higher chance of developing dementia. When they occur together, the risk may increase even further.
Despite this, many people do not receive hearing support. Globally, only a small percentage of people who could benefit from hearing aids actually use them.
For people with memory difficulties, managing hearing aids can be even more challenging. To help address this, researchers designed a personalised hearing support programme tailored specifically for people with MCI.
What Did the Study Involve?
The pilot study took place in NHS memory clinics in London. It involved 58 adults aged 55 and older who had both MCI and untreated hearing loss.
Participants were divided into two groups. One group received hearing aids and four home visits over three months, which included help with fitting, using the devices, and improving communication. The other group received general healthy ageing advice and a letter suggesting they speak to their GP about hearing care.
The goal was to see whether people with MCI would engage with hearing care and whether consistent hearing aid use could help with mood, memory, and overall wellbeing over six months.
What Did the Study Find?
The results were very promising.
- In the personalised support group, 83 percent of participants were fitted with hearing aids, compared to only 21 percent in the standard care group.
- In the same group, 75 percent reported using their hearing aids daily, compared to just 22 percent in the control group.
- Most participants in the support group attended multiple visits, showing strong engagement.
There were also signs of improvement in memory, mood, and quality of life among those receiving the hearing intervention. Although this was a small pilot study, the outcomes suggest that hearing support can make a meaningful difference for people with memory difficulties.
Why This Matters
This study shows that with the right support, people with MCI can successfully use hearing aids. It also suggests that addressing hearing loss could have broader benefits for brain health and wellbeing.
Importantly, it also highlights that standard NHS pathways (and comparable processes in Ontario’s healthcare system, such as relying solely on a GP referral) may not be sufficient.
A more personalised and supportive approach can help ensure that hearing loss is not overlooked.
What Happens Next?
Based on these encouraging results, researchers are planning a larger trial. This will include longer follow-up to assess whether hearing support can slow cognitive decline or delay the development of dementia. It will also explore the cost-effectiveness of offering this type of care more widely.
What Can You Do Now?
If you or someone close to you is noticing hearing changes or memory concerns:
- Book a hearing test, especially if you are over 55
- If you are prescribed hearing aids, try to wear them regularly, even if it takes time to get used to them
- Ask about extra support options, especially if memory is also a concern
Looking after your hearing is not just about hearing better. It can help you stay connected, improve how you feel, and may even help protect your brain.
