Wearing Hearing Aids Could Significantly Reduce Your Risk of Alzheimer’s Disease
January 28, 2026
Hearing aids serve as a crucial tool for individuals experiencing hearing loss. Despite their benefits, many who could gain from these devices often choose not to wear them, frequently due to feelings of embarrassment associated with using such technology.
But here’s an intriguing reason to reconsider: wearing hearing aids could potentially lessen the risk of developing Alzheimer’s disease. A recent study conducted by researchers in Australia revealed that while hearing aids did not seem to enhance memory or cognitive skills in those with moderate hearing loss, they were linked to a reduced likelihood of Alzheimer's and other forms of dementia.
Joanne Ryan, a researcher from Monash University in Melbourne, Australia, emphasized the importance of this finding: "As we age, hearing loss becomes increasingly common, and prior research indicates it may elevate the risk of cognitive issues, including dementia. However, the effects of treating hearing loss with hearing aids on brain health have been less explored. Our study monitored individuals with hearing loss, some of whom received hearing aids while others did not. Although we found similar cognitive scores between both groups, those with hearing aids showed a lower risk of developing dementia."
In conducting this study, researchers examined 2,777 men and women in Australia, with an average age of 75, all of whom reported moderate hearing loss but did not use hearing aids. Importantly, none had been diagnosed with Alzheimer's disease or any type of dementia at the start of the study.
Over the course of seven years, participants took annual assessments to evaluate their memory and cognitive abilities. During this period, 117 individuals received a diagnosis of Alzheimer’s or another form of dementia, while 664 were given hearing aids.
When comparing the two groups, researchers found it surprising that, generally speaking, the use of hearing aids did not correlate with improved memory or cognitive test scores. One potential explanation for this could be that most participants began the study with relatively good cognitive health, which might limit the extent of improvement achievable through hearing aids.
However, after controlling for various risk factors like age and other medical conditions, such as diabetes and heart disease, the study illuminated a significant finding: those prescribed hearing aids had only a 5 percent risk of developing dementia during the study, in contrast to an 8 percent risk among those who did not use hearing aids. This represents a substantial 33 percent reduction in the risk of dementia. Furthermore, as the frequency of hearing aid usage increased, so did the decrease in dementia risk.
Additionally, the researchers noted that the group using hearing aids had a 36 percent chance of experiencing any cognitive impairment—including cognitive decline and dementia—compared to 42 percent in the non-users. This corresponded to a 15 percent reduced risk of cognitive deterioration.
"While we didn’t observe differences in cognitive scores, our findings suggest that for older adults suffering from hearing loss, utilizing hearing aids could lower the chances of dementia and cognitive impairments, thereby promoting better brain health," Dr. Ryan stated. The results of this research were published in Neurology, the esteemed medical journal of the American Academy of Neurology.
It's important to note that the study only established a correlation between receiving hearing aids and a decreased risk of dementia. Nonetheless, a growing body of evidence supports that maintaining good hearing is vital for preserving brain health as we age. Effective hearing can foster greater social interactions, which are believed to play a critical role in sustaining cognitive function. Among modifiable risk factors for dementia, inadequate hearing appears to pose a more significant threat than smoking, hypertension, or insufficient physical activity.
The positive aspect is that high-quality over-the-counter hearing aids are becoming increasingly accessible and affordable, with many designs being discreet and unobtrusive. If you think you might benefit from hearing aids, don’t hesitate to consult your doctor about what options might suit you best. Investing in a quality hearing aid could not only enhance your quality of life but may also contribute to maintaining your mental acuity for years to come.
