Among cognitively normal older women, hearing loss in the right ear is associated with cortical thinning, a surrogate marker for neurodegeneration.
Why this matters
Although hearing loss is an established risk factor for dementia, the association between hearing loss and neurodegeneration is unknown. Previous studies investigating the link between hearing loss and cortical thinning show inconsistent results. Understanding this association may help to contribute to the prevention of dementia through management of hearing loss.
