Several scientific studies have found that there is a close relationship between untreated hearing loss and the risk of developing dementia.
A large French scientific study, which has followed nearly 3,800 people over a 25 year period, has found that seniors and elderly people who say that they have a hearing loss and do not use hearing aids are at a much higher risk of dementia.
Earlier results from the same French study documented that self-reported hearing loss is independently associated with accelerated cognitive decline in elderly adults.
A large Australian study has also found that there is a strong relationship between hearing loss and dementia. The study found that older Australian men had a 69% increased risk of dementia for those who report having a hearing loss.
A British study has confirmed the association between hearing loss, dementia and cognitive decline. Two American studies have also confirmed a relationship between hearing loss and general cognitive decline.
