Dementia is not just memory loss

It is crucial to raise awareness and expand public understanding of Alzheimer’s disease and other types of dementia. Over 55 million people are currently living with dementia, a number that continues to grow. This condition is projected to affect at least 250 million people globally, with societal costs exceeding 1.3 trillion dollars annually.

Dementia, once seen merely as 'forgetfulness in the elderly,' is now recognised as a serious condition that goes beyond normal aging. It includes various progressive brain disorders that affect memory, cognition, behavior, and emotions, with Alzheimer's disease being the most common, accounting for up to 60% of cases. Symptoms often include memory loss, difficulty with communication, trouble performing routine tasks, and changes in personality and mood.

Hearing loss key contributor to Dementia

Hearing loss is increasingly acknowledged as a significant risk factor for dementia, with the Lancet Commission identifying it as the most notable modifiable risk factor. Approximately 8% of the modifiable risk for dementia is attributed to hearing loss. However, while research is ongoing, and the connection between hearing loss and cognitive decline is not yet fully understood, hearing aids can improve communication and overall well-being.

Although dementia is currently incurable, there are treatments and support options available to manage symptoms and maintain quality of life. Lifestyle changes and societal adjustments can help reduce the risk of dementia. Research highlights 12 modifiable risk factors, which, if addressed, could potentially prevent or delay up to 40% of dementia cases.

Hearing aids effectively manage hearing loss

To support healthy aging and living, it is essential to improve public and medical understanding of dementia and related conditions like hearing loss. The World Health Organization recommends hearing screening and the provision of hearing aids for older adults to manage hearing loss effectively and potentially mitigate its impact on brain health.

Australian Government recommends regular hearing checks for over 50s

Turning 50 is a good time to think about your future, and how you can stay healthier for longer. This includes your brain health and reducing your risk of dementia.

Dementia can affect memory, thinking and mood. Some cases can’t be avoided, but did you know that nearly half of all dementia cases could be prevented or delayed? There are things you can do that can make a real difference – you may already be doing some of them.

It’s never too early, or too late, to reduce your dementia risk
