• Hearing loss can make the brain work harder to fill in missing sounds, reducing cognitive resources and causing fatigue, concentration problems, and social withdrawal.
• Long-term studies link hearing loss to increased risk of cognitive decline; even mild hearing loss has been associated with a doubled dementia risk.
• Hearing health is a modifiable dementia risk factor. Addressing it alongside social, cardiovascular, and physical health may reduce risk.
• Ear360 is a 10-point hearing assessment (now including Sonde Health cognitive and wellbeing measures) that evaluates hearing impacts on memory, sleep, balance, tinnitus, and daily mental fitness.

It is natural to feel worried if you’ve noticed changes in your memory or ability to concentrate. These changes can be linked to hearing, even if that’s not obvious at first. There is a well-researched link between hearing loss and how the brain processes information, so it’s often helpful to look at hearing and cognition together rather than separately.

Is it hearing loss or is it memory loss?

When you have a hearing loss, your brain doesn’t receive the information it expects and must work extra hard to fill in the gaps, pulling resources away from the “thinking” (cognitive) parts of your brain.

Over time, more of your brain’s energy is spent on everyday tasks, such as following conversations, especially in noisy environments. That extra effort can lead to accelerated cognitive decline, social isolation, and leave you feeling mentally exhausted.

In real life, this could look like:

• Feeling unusually drained after social situations
• Struggling to concentrate or keep track of details
• Withdrawing from conversations without really meaning to

The connection between hearing loss and cognition

Long-term studies have shown a strong link between hearing loss and cognitive decline. Research from Johns Hopkins University found that even mild hearing loss doubled the risk of dementia. This does not mean that hearing loss automatically causes dementia, but it can increase your risk of cognitive decline.

The Lancet Commission on Dementia Prevention has identified hearing loss as one of the most significant modifiable risk factors for dementia. This means that looking after your hearing health is an important step in reducing risk, alongside maintaining social connections, managing cardiovascular health, and staying physically active.

Find out what’s really going on

The connection between hearing and your overall wellbeing is why we created Ear360, our 10-point hearing health assessment. Ear360 goes far beyond the sounds you can hear and looks at how it affects other areas of your life, including memory, sleep, balance and tinnitus.

In 2025, we enhanced the assessment to include new mental and cognitive fitness wellbeing factors, powered by Sonde Health, helping you better understand how your brain processes sound and how it leaves you feeling throughout the day.
