AAIC 2023 | The link between hearing loss and dementia: increased cognitive load

Dona Jayakody, PhD, University of Western Australia, Perth, Australia, speaks on the role of increased cognitive load in the association between hearing loss and dementia. It is well established that hearing loss is a risk factor for dementia, but a causal mechanism remains unclear. One explanation could be enhanced listening effort in individuals with hearing loss, leading to an increased cognitive load. Hearing loss is particularly common with regards to high frequency sounds, meaning individual must ‘fill in’ the auditory information at these pitches. This requires extra effort from the individual, therefore increasing cognitive load. This interview took place at the Alzheimer’s Association International Conference (AAIC) 2023 in Amsterdam, Netherlands.
