Hearing loss isn't just about struggling to hear conversations—it may significantly impact brain health. Emerging research reveals a critical link between hearing and cognitive function, suggesting potential long-term implications for mental well-being.
Why it matters
Untreated hearing loss can negatively impact cognitive abilities. However, this study found that long-term hearing aid use may reduce that risk.
In a nutshell
The study investigated how hearing loss severity relates to cognitive function and whether hearing aid use influences cognitive performance.
- Researchers compared people 55 and older with hearing loss. They divided them into those who had never used hearing aids and those who had used them for over three years.
- They assessed hearing levels and cognitive function using the Mini-Mental State Examination (MMSE) and the Symbol Digit Modalities Test (SDMT). Then, they analyzed the data to determine how these factors were related.
By the numbers
- 117: The total number of participants with hearing loss involved in the study.
- 55: Participants who had no prior experience with hearing aids.
- 62: Participants who were long-term hearing aid users.
- 38.75 dB HL: The hearing threshold (in decibels) identified as potentially impacting cognitive function in those not using hearing aids. People with hearing loss worse than this cutoff had lower scores on cognitive tests.
The takeaway
- Early Intervention: A hearing threshold above 38.75 dB HL was associated with lower cognitive function scores for those who haven’t used hearing aids. This suggests earlier intervention with hearing aids would be beneficial.
- Long-Term Benefits: The most encouraging finding is that long-term hearing aid users didn't show the same negative correlation between hearing loss and cognitive function. This supports the idea that consistent hearing aid use helps protect cognitive abilities.
- Yes, but: More studies are necessary to fully understand the long-term impact of hearing aids on cognitive health, especially using more sensitive cognitive assessments and larger sample sizes.
