Making sense of hearing-related neurocognitive impairment: The Auditory Ageing and Cognitive Impairment Study (AUDACIOUS)

Dr Kim Kiely (Lead Investigator), Professor Kaarin Anstey (Associate Investigator) and Dr Ranmalee Eramudugolla (Associate Investigator)

With increasing age, nearly all adults experience progressive, irreversible, and bilateral declines in hearing ability. As a result, hearing loss is one of the most common chronic health conditions affecting older adults and if unmanaged its impacts are wide ranging and long lasting.

There is good evidence indicating that older adults with significant hearing difficulties are more likely to experience cognitive decline and dementia, but reasons for this association are unknown.

This project will investigate how hearing loss is related to cognitive impairment. Firstly, it will compare levels of hearing function and use of hearing services by cognitive status. Second, it will examine if the relationship between poor hearing and impaired cognitive functioning is explained by lower levels of participation in activities that are good for brain health. Third, it will investigate if hearing rehabilitation services and hearing aids protect against poorer levels of cognitive function.


The project is funded by a Dementia Australia Research Foundation (DARF) Project Grant
