Recent studies suggest a potential link between tinnitus and dementia. However, the connection is still unclear and more research on this topic is required to support this claim.
What we do know is that hearing loss is a known risk factor of cognitive decline and that people with tinnitus have some degree of hearing loss. However, there is no evidence to suggest that tinnitus itself has any effect on cognitive decline.
While researchers are still trying to fully understand the relationship between tinnitus and dementia, some studies have suggested that people with severe tinnitus may have a higher risk of developing early-stage dementia. However, this is likely because individuals who experience severe tinnitus are much more likely to have severe hearing loss.
