In a groundbreaking revelation, recent research reveals a critical link between hearing loss and cognitive decline. Previously thought to be an isolated issue, hearing loss is now a marker for future cognitive impairments.
Early intervention with amplification-based assistance, coupled with proactive hearing care, can help mitigate the risks associated with cognitive impairments.
A comprehensive study published in Ageing Research Reviews analysed data from over 1.5 million participants. The findings are alarming and conclude a link between an individual’s hearing ability/hearing loss, and their risk of future cognitive decline. The study concluded the following:
- 35% increased risk of dementia (HR=1.35)
- 29% increased risk of mild cognitive impairment (MCI) (HR=1.29)
- 56% increased risk of Alzheimer’s disease (HR=1.56)
- Every 10-decibel worsening of hearing was associated with a 16% increase in dementia risk.
These statistics highlight the urgency of addressing hearing loss not just as a communication issue, but as a significant factor in brain health and longevity.
Early intervention and offsetting the loss is key
Addressing hearing loss isn’t just about improving communication; it’s about safeguarding your brain health and enhancing your longevity.
Untreated hearing loss can lead to social isolation, depression, and now we know it is also associated with significantly increased risks of cognitive decline and dementia. Adopting hearing aids or at least taking part in some form of amplification-based assistance via readily available products, to offset the difficulty experienced earlier rather than later, can make a significant difference.
This growing body of evidence highlights the necessity for early adoption of hearing aids, which are essential tools in maintaining cognitive function and quality of life.
Using hearing aids early can reduce the negative impacts of hearing loss on the brain, supporting better mental health and long-term wellness.
Prioritising hearing health is a vital component of a comprehensive approach to longevity and cognitive well-being. The evidence is clear: addressing hearing loss early with appropriate interventions like hearing aids not only improves hearing but also plays a significant role in maintaining cognitive function and overall brain health.
Practical Advice for Better Hearing and Cognitive Health
Here are some steps for individuals to protect their hearing and in the long term, their cognitive health.
1. Early adoption of hearing aids or amplification-based stimulation is crucial
Begin using hearing aids or apply amplification-based stimulation at the first sign of hearing loss or hearing difficulty. Research shows that early use can significantly reduce the risk of cognitive decline by maintaining brain stimulation and preventing auditory deprivation.
2. Use of Assistive Listening Devices (ALDs)
In the absence of a hearing aid, incorporate ALDs like amplified telephones, TV listening systems and headphones, and personal FM systems into your daily routine. These devices can help you hear better in various environments, reducing cognitive strain.
3. Whatever you choose to use, use it frequently.
Consistency is key, and the quality of what you hear is also important. Ensure your chosen hearing aid or hearing device is functioning correctly, with regular maintenance to ensure correct operation. Clean them regularly and replace batteries or parts as needed to ensure optimal performance and continued cognitive benefits.
4. Broad spectrum stimulation is important.
The human hearing range covers a broad range of frequencies. It’s important to receive amplification across this broad spectrum of sounds. It’s also important to experience a wide variety of sounds, ranging from music to human speech, and even the things that are happening all around you, such as environmental sounds.
5. Direct-to-you hearing devices, known as ‘pocket aids,’ are now available online, allowing people to choose ready-to-use hearing aids at a more cost-effective price than traditional options.
Thanks to lowering costs of high-end hearing aid technology, cost is no longer a reason to prevent you from getting a great hearing device. People now have access to a large range of cost-effective hearing aids or what is being called a ‘pocket aid’, which is a very low-cost, yet highly effective hearing device. Often, they are just as small, or even smaller than the world’s most advanced hearing aids.
6. Choose technology that has a great reputation for sound quality, and comfort.
Advanced technology in hearing devices can help focus on specific sounds and reduce background noise, supporting better cognitive processing and reducing mental fatigue.
7. Get regular hearing check-ups.
Schedule annual hearing tests, especially if you’re over 50 or notice any hearing difficulties. Early detection of hearing loss can help you address the issue before it impacts cognitive health.
8 Avoid loud noises and protect your hearing.
Protect your hearing from further damage by avoiding loud environments and using ear protection when necessary, such as earplugs or headphones. Reducing exposure to loud noises can help maintain your current hearing levels and prevent additional cognitive risks associated with worsening hearing.
9. Stay socially engaged.
Engage in social activities and communicate regularly with friends and family. Social interaction can stimulate your brain and help prevent the isolation and depression associated with hearing loss, which are linked to cognitive decline.
10: Seek professional advice for a solution that meets your needs.
Consult with hearing specialists or take the advice of a trained hearing professional, to tailor hearing solutions that fit your lifestyle. Personalised or adjustable devices, can ensure optimal hearing support, promoting better mental health and cognitive function.
Prioritise your hearing health for longevity
The evidence is clear: addressing hearing loss early with appropriate interventions not only improves hearing but also plays a significant role in maintaining cognitive function and overall brain health.
