Hearing loss and dementia


In light of World Hearing Day which is coming up on the 3rd March, we thought it was the perfect time to discuss hearing loss. Currently, around 500 million people worldwide have moderate to profound hearing loss. This number is predicted to grow to around 900 million by 2050. Hearing loss affects 1 in 3 older adults and has debilitating effects on communication, quality of life and well-being.

Audiologists, the professionals who assess, diagnose, and treat hearing loss, have shown for some time how hearing loss can result in social isolation, loneliness, and depression.

Recent research from the Lancet Commission on Dementia suggests hearing loss acquired in mid-life, that is not recognised or well managed, is a potentially modifiable risk factor for dementia – and social isolation and depression are additional risk factors. Here at the Wicking Centre, we are working on helping people understand the consequences of hearing loss and the relationship to dementia risk. With thanks to 7,442 ISLAND Project participants who responded to a survey about hearing loss, 17% (1,274 participants) reported they had a hearing loss, with 43% of these participants (n=548) stating that their hearing loss had not been corrected or corrected to their satisfaction. These 548 participants also reported more difficulties with social isolation, lack of social support, anxiety, and depression.

Recent data from the National Health and Aging Trends Study in the United States shows that self-report of hearing loss underestimates actual hearing loss, highlighting the importance of going to see an audiologist whenever you have any concerns about changes in your hearing. Our ongoing research seeks to assist in uncovering the relationship between hearing loss and dementia, including uncorrected hearing loss being a source of chronic stress, and whether improved prevention and management of hearing loss could indeed prevent some cases of dementia or certainly slow the progression of this condition.
