As we approach Dementia Action Week this month, it is crucial to shed light on the link between dementia and hearing loss, particularly in the context of social isolation.

Australians aged 60 years or older need to be aware of the potential risks associated with untreated hearing loss and the steps they can take to ensure they remain an active part of their communities.

The link between hearing loss and dementia 

Studies have shown a significant connection between untreated hearing loss and the development of dementia. 

In fact, moderate hearing impairment can increase one’s dementia risk three-fold. Moreover, the decline in memory and cognitive abilities can occur up to 40% faster in individuals with hearing loss compared to their counterparts with normal hearing. 

The exact reasons behind this link are still being studied, but one potential explanation researchers have suggested is overtaxing of the brain. When the ears receive sounds, they transmit them to the brain for processing. However, if the messages from the ears are unclear, the brain must work harder to understand them, which can lead to an overworked and weakened working memory. Additionally, social isolation, which is more common among people with hearing loss, could further heighten the risk of dementia.

The importance of managing your hearing loss

The good news is that managing hearing loss is thought to help reduce the risk of developing dementia. Whether you currently have a hearing loss or not, regular hearing checks are essential for monitoring any changes in your hearing ability. If a hearing loss is detected, seeking appropriate management may benefit your cognitive health.

Embracing community and social connections

Apart from managing hearing loss, staying socially engaged is a powerful way to combat isolation and promote overall well-being. Being part of a community and maintaining social connections can have a positive impact on mental health and cognitive function. Engaging in various social activities, joining clubs, attending events, or participating in volunteer work are excellent ways to foster a sense of belonging and strengthen bonds with others. 

Incorporating regular physical activity

Physical activity is not only beneficial for maintaining physical health but also plays a role in cognitive well-being. Regular exercise has been shown to help improve memory and cognitive function and may also help to reduce the risk of dementia. Activities such as walking, swimming, dancing, or participating in group exercise classes can be enjoyable ways to incorporate physical activity into daily life.

Cognitive stimulation

Keeping the mind active through cognitive stimulation can also contribute to cognitive resilience. Engaging in activities that challenge the brain, such as puzzles, games, reading, or learning new skills, can help maintain mental sharpness and cognitive abilities.

Encouraging community support

As part of Dementia Action Week (18-24 September, 2023), we want to emphasise the importance of community support and understanding. Supporting individuals with dementia and their families is vital in fostering a compassionate and inclusive society. By raising awareness and promoting understanding, we can create a more dementia-friendly community that values and respects individuals living with dementia.

In conclusion, the link between hearing loss and dementia highlights the significance of addressing hearing impairment early on to help protect cognitive health. By managing hearing loss, we can help reduce the risk of isolation and promote overall well-being. Let's make this Dementia Action Week a time to come together, embrace our community, and support each other on this journey.

As you take steps to stay connected and look after your cognitive health, remember to prioritise your hearing health too.
