Age-related hearing loss and cognitive decline. The potential mechanisms linking the two.
- Dementia: One of the largest modifiable risk factor for dementia.
- Mid-life hearing loss, if eliminated, might reduce the risk of dementia by 9%.
- Theory: Hearing loss causes the brain to put extreme effort into listening diverting it from cognitive tasks. Therefore, continually reducing the amount of cognitive function.
- Age-related hearing loss is associated with smaller brain volume and that hearing impairment causes accelerated rates of brain atrophy.
- Studies have found that elderly individuals with audiometric-defined hearing loss have decreased volumes in their primary auditory cortex and or total brain volume.
- Use-it-or-lose-it. If one does not continue to use his or her listening and processing abilities, he or she might lose those abilities.
