Competencies
Research
Despite great activity to understand the mechanisms behind dementia and find a curative cure or disease-modifying treatment, no one has succeeded. This has led to an increased focus on alternative methods – e.g. modifiable risk factors.
Hearing and risk of dementia
Background
Although hearing loss is considered an important modifiable risk factor for dementia, the evidence for the link between hearing loss and dementia is still limited. Recent literature reviews of the connection between hearing loss and dementia conclude that hearing loss is associated with a higher incidence of dementia.
Aims and objectives
Hearing loss has been identified as perhaps the most important modifiable risk factor for dementia with a potential risk reduction of 9% if it were removed. The project aims to map impaired hearing in mid-life as a risk factor for dementia.
Method
This is a cohort study. Data from the hearing study in HUNT2 (1995) and HUNT4 (2019), HUNT4 70+ and data from the HUNT biobank (HUNT1 1984, HUNT3 2006) will be used in the analyses.
Results
The results of the study are published in eClinicalMedicine: "We found a moderate association between objectively measured hearing impairment and dementia in the younger age group (<85 years). The findings of no association in the older age group (≥85 years) might be due to the competing risk of death. The present study adds to the literature showing that acquired hearing impairment is a risk for dementias over a period which is too long for reverse causation, and with thorough consideration of confounders. Further research is needed to investigate associations between the different aetiologies of hearing loss and dementia subtypes, and risk differences for sexes."
