how hearing loss may affect dementia

There are lots of reasons why people develop dementia and there are different types of dementia too. It is not fully known why there is a link between but several studies have found an association between hearing loss and the risk of developing dementia. Hearing loss is a common problem among older adults and can be an early indicator of cognitive malfunctions. Recent aging research not only shows that the two are connected but have found that those with mild hearing loss are more likely to develop dementia. Living with both conditions can present challenges which can affect their ability to take part in everyday life and communicate. This is because the brain has to work harder in order to process sound, leading to an increase in cognitive effort.

Some theories state that because hearing aids help you hear more clearly, less ‘brain energy’ is required to figure out what is being said and to hold a conversation. The reduced listening effort, means there is less ‘strain’ on the brain and has more ‘energy’ to fight off weakening changes, which could go on to become dementia. People aged 65 years or older showed an increased dementia rate except for those using hearing aids.

Both identification and management of hearing loss are particularly important and without this, the dementia may appear worse. For example, if a person with dementia is having difficulty using their hearing aid then this is likely to make it harder for them to follow communication and may make them seem more confused and withdrawn.

Hearing loss is a large modifiable risk factor when it comes to lowering the risk of dementia.

Hearing loss might result in cognitive decline through reduced cognitive stimulation so it’s important for people with dementia to have regular hearing tests. Hearing aids are made to support your brain by helping you to process sound so that you can keep your brain mentally stimulated.

Treating hearing loss with hearing aids helps to keep you mentally stimulated and protects against cognitive decline; also, cochlear implants can help restore hearing and improve overall well-being. Continued research finds that, for people with hearing loss, wearing their hearing aid or having a cochlear implant may reduce their risk of long-term cognitive decline by up to 19%.

It is important for people with hearing difficulties to take steps to protect their brain health; early diagnosis and treatment of hearing loss can help reduce the risk of developing dementia later on in life.
