Ulster University | 16 February 2021 | Hearing aids may protect against progression to dementia, study shows
The journal Alzheimer’s & Dementia: Translational Research & Clinical Interventions, has this week published a paper which is the first to examine the effect of the use of hearing aids on the conversion from mild cognitive impairment (MCI) to dementia and risk of death. An international team of scientists led by an academic at Ulster Universiity, Dr Magda Bucholc, analysed data from the National Alzheimer’s Coordinating Center (NACC). A little over 2 000 adults aged 50 and over with hearing impairments participated in this piece of research. Their cognitive status ranged from MCI to dementia. This study is novel as it is the first of its kind to . MCI involves decline in cognitive abilities greater than normal age-related changes but not severe enough to meet diagnostic criteria for dementia. Many individuals with MCI do not progress to dementia and may even regain normal cognitive ability.
The experts tested if the use of hearing aids is independently associated with a decreased risk of incident all‐cause dementia diagnosis for MCI patients and reduced risk of death in individuals with dementia. This study also examined if the rate of cognitive decline is slower for hearing aid users when compared to those not using hearing aids.
They report that among hearing‐impaired adults, hearing aid use was independently associated with reduced dementia risk have (Sources: University of Ulster; Bucholc et al, 2021).
