Specific neurobiological link identified between hearing loss and cognitive decline

Presbycusis is a prevalent form of age-related hearing loss that also hinders speech recognition. While scientists have linked hearing loss to an increased risk of cognitive decline, the biological "bridge" between the two has remained unclear.

How age-related hearing loss may affect the brain and memory

Age-related hearing loss, known as presbycusis, affects millions of older adults and often makes it difficult to understand speech, especially in noisy environments. Scientists have long observed that people with hearing loss are more likely to experience cognitive decline, including problems with memory and thinking. However, the biological link between the two has remained unclear. […] The post How age-related hearing loss may affect the brain…

Why hearing loss can be a sign of cognitive decline - Health Care Today

A new study finds an association between hearing loss and cognitive decline via shared changes in the brain. Structural atrophy and functional decline coupled together in specific areas of the brain correlated with both ‘worsening hearing thresholds and cognitive impairment.‘ The study authors propose the ‘Functional-Structural Ratio’ or FSR as a way to measure these coupled changes, which could potentially become a tool for assessing dementia r…

Identifying the Neural Link Between Hearing Loss and Dementia

Researchers identify the Functional-Structural Ratio (FSR) as the biological link between age-related hearing loss and cognitive decline, offering a potential new biomarker for dementia risk.
