Cognitive function and hearing loss

Home > Research > Clinical Research > Clinical Research Projects > Cognitive function and hearing loss

Currently a hot research topic worldwide, Ear Science is part of a large effort to understand the relationship between our hearing and our cognitive skills. Key questions are: What cognitive skills are associated with hearing loss? Does hearing loss contribute to a reduction in cognitive skills, and perhaps even dementia? And, will the use of a hearing aid or hearing implants restore cognitive skills? 

These are important questions, especially as the number of people with hearing loss grows and the number of people with dementia also grows with an ageing population. Our early findings confirm that indeed hearing loss affects some components of cognition.

Our team aims to leverage findings to potentially interrupt cognitive decline by improving hearing through hearing instruments and implants inspiring earlier and more widespread uptake.
