There is growing evidence that suggests a link between hearing loss and dementia. Research indicates that individuals with untreated hearing loss are at a higher risk of developing cognitive decline and dementia compared to those without hearing loss. The exact mechanisms behind this relationship are still being studied, but it is believed that the brain's increased effort to process sound may divert resources from other cognitive functions, leading to cognitive decline. Additionally, social isolation and reduced cognitive stimulation, often associated with hearing loss, can contribute to the development of dementia. Early detection and treatment of hearing loss may help reduce the risk of cognitive decline.
