Untreated hearing loss in older adults has been linked to faster cognitive decline and even increased dementia risk. When the brain has to work overtime to hear, it takes a toll on memory, focus, and mental clarity, often leaving a person tired at the end of the day. Add in social isolation, and the impact is even greater.
But here’s the good news. Treating hearing loss may actually slow down cognitive decline. Lets explore this in more detail.
What is dementia?
Dementia is a group of symptoms that can affect memory, problem-solving, language, and behaviour, making it hard for someone to carry out activities alone. Alzheimer’s disease is the most common type of dementia.
Is there an association between adult-onset hearing loss and dementia?
Yes, there is. However, an association means that someone with a hearing loss is more likely to have dementia, and likewise, someone with dementia is more likely to have a hearing loss.
Is hearing loss a big problem in the world?
The World Health Organisation (WHO) states hearing loss is the third leading cause of disability worldwide.
What are the consequences of untreated hearing loss?
Hearing loss can lead to communication difficulties, which can lead to social isolation and withdrawal, depression, and ultimately a reduced quality of life. Adults often overlook hearing tests and, on average, wait around 7 years from first noticing a problem to get their hearing tested.
Is there any evidence that getting help with hearing is a good thing
Yes, there is. In 2024, Lancet (which is a highly regarded medical science journal) published a report which essentially stated that treating a person’s hearing loss can reduce the chances of acquiring dementia or reduce its impact if it is acquired.
Will wearing hearing aids reduce my risk of getting dementia?
Hearing aids are amazing devices that allow people to hear better in many different situations. This leads to more social engagement, less tiredness, better quality of life, and increased well-being, which can only be a good thing. Research is still looking at whether using hearing aids reduces the risk of dementia; however, current findings are encouraging.
What is the take-home message?
Hearing loss is one of the most significant health issues in the world. Left untreated, hearing loss can lead to social withdrawal and reduce a person’s quality of life. Modern hearing aids are incredibly beneficial and can massively improve a person’s ability to hear and quality of life. They connect to smartphones, allow music and audio streaming from many devices, including the TV, and use the latest technology to help people hear in even the most challenging environments.
If you feel you are not hearing as well as you used to, or you know someone who would benefit from a hearing assessment, do not delay. Book a hearing test and find out if there is a hearing problem. With the right audiologist, you can start your journey to better hearing.
