Previous studies have shown the link between hearing loss and dementia¹, but a new report suggests that caring for your hearing health may help protect against cognitive decline.

Medical journal The Lancet published a report on 30 July 2020 which indicates that hearing loss is a significant modifiable risk factor against dementia.²

The Lancet study states that “hearing loss might result in cognitive decline through reduced cognitive stimulation”. The journal encourages taking measures to manage hearing loss.

Being proactive and managing hearing loss as soon as possible, may reduce the risk for cognitive decline and dementia.^{1, 2, 3, 4}

Modifiable risk factors

There are 12 lifestyle factors, including hearing loss, which account for around 40% of dementia cases worldwide.

The Lancet study suggests that reducing these risk factors may decrease the risk of developing dementia.

These risk factors include:

• Less education
• Hypertension
• Excessive alcohol consumption
• Obesity
• Smoking
• Depression
• Social isolation
• Physical inactivity
• Air pollution
• Diabetes
• Hearing loss.

Modifying these risk factors might prevent or delay up to 40% of dementia cases.²

Keeping the brain mentally stimulated

As one of our most important senses, hearing allows us to connect with others and live an active lifestyle.

Studies have linked untreated hearing loss to withdrawal from social situations, social isolation, stress, depression, and reduced performance at work or during education.

Another study notes that “hearing impairment is associated with a 30-40% rate of cognitive decline”.⁴ Managing your hearing loss and making sure your brain stays mentally stimulated is one way you can help protect yourself against the risk of cognitive decline.^{2, 4}

Keeping the gateways to communication open by managing your hearing loss could help facilitate a healthy and active lifestyle through all stages of life – especially in mid to later stages of life where the risk for dementia increases.^{1, 5}

Improve your long-term heath

It is important to take good care of your ears. Protecting your ears from excessive loud noise could help prevent hearing loss.¹ If you think you might have hearing loss, it’s a good idea to get your hearing checked so that you can manage it.
