Hearing loss and dementia: Are they linked?

Hearing loss and dementia are both considerable concerns for the ageing population across the UK and globally, but is there a connection between them? We know hearing loss does not directly cause dementia, the goal of this blog post is to explore the relationship between hearing loss and dementia, as well as discussing preventative measures.

What is dementia?

Dementia is a term that refers to the decline in cognitive functions like memory, thinking, language, and problem-solving. It can also affect mood and behaviour.  There are a few different forms of dementia, including Alzheimer’s disease, Lewy body, vascular, and frontotemporal.
There are various symptoms, although the main ones include:

• Short-term memory
• Reduced concentration
• Increased confusion
• Failure to do everyday chores
• Behavioural changes

The symptoms of dementia are progressive, meaning that cognitive impairment gets worse over time. Dementia is an extremely sensitive topic and if you recognise these symptoms in yourself or a loved one, don’t neglect them – speak to a professional.

How is dementia linked to hearing loss?

​Hearing loss and dementia often occur together in older individuals, but what’s the connection?
Individuals with hearing loss are at greater risk of acquiring dementia. Furthermore, some studies claim that hearing loss is an independent risk factor for dementia, accounting for 9% of cases.
One argument is that hearing loss results in someone being less socially engaged. As social time is critical to being intellectually stimulated, isolation and loneliness could lead your brain to be less active on a frequent basis.
Another way that hearing affects dementia is the way it depends on your brain to work harder. Indeed, the brain’s effort to compensate for hearing loss could divert resources away from cognitive functions. In turn, this could quicken cognitive deterioration.

​How can hearing aids help with dementia?

According to a study on hearing loss and dementia, hearing aids could slow cognitive decline in people of higher risk, such as individuals with dementia. By reducing the impact of hearing loss and keeping auditory pathways active, hearing aids can enhance hearing clarity and help people reengage with their surroundings. By being able to maintain social connections, individuals can continue stimulating their brains whilst avoiding isolation and depression, common challenges for people with untreated hearing loss.

​Early prevention advice for hearing loss and dementia

Early prevention measures can be critical in addressing hearing loss and its possible impacts on dementia. Let’s take a look at some simple actions you could carry out.

Regular hearing check-ups
Frequent hearing check-ups in older adults can help professionals detect hearing loss early on. Thus, by using hearing aids early on, individuals may be able to maintain cognitive function and enhance their overall well-being. Book a hearing test or full diagnostics with us online here.

Stay socially engaged
By making sure you stay socially active, you can keep yourself intellectually stimulated and ward off the potential challenges tied to isolation and loneliness.

Maintain a healthy lifestyle
Eating healthily, exercising regularly, and participating in mental and physical exercises can help support brain health, which is crucial to delay the weakening of cognitive functions.

Current research supports a case for audiologists providing cognitive screenings to meet the needs of certain patients. Find out more here.

Hearing aids help to slow the brain aging process

A recent study published by medicalexpress.com found that hearing aids helped slow the brain again process in adults with mild cognitive impairment! Read the study here.
