Dementia is rapidly emerging as one of the most pressing health challenges of our time, yet it remains one of the most misunderstood. According to the World Health Organization (WHO), more than 55 million people worldwide are currently living with dementia, with an additional ten million new cases diagnosed every year. These figures predominantly reflect recent trends in Western nations.
According to Dementia Australia, currently an estimated 433,300 Australians are living with dementia, and around 29,000 under the age of 65 years are diagnosed with younger-onset dementia. The condition is now the leading cause of death among Australian women, who are twice as likely as men to develop it. In 2024, dementia was on track to surpass heart disease as the leading cause of death for all Australians, as reported by the Australian Bureau of Statistics in 2023.
Dementia is an umbrella term for a range of symptoms caused by various brain disorders, with Alzheimer’s disease being the most common, accounting for 60-80 per cent of cases. While symptoms and severity vary, dementia typically involves a progressive cognitive decline, affecting memory, reasoning, decision-making, and mood. It is a debilitating condition with no known cure, though treatments exist to help manage certain symptoms and improve quality of life for both individuals living with dementia and their caregivers.
Complex causes
For decades, Alzheimer’s disease has been viewed as irreversible and largely untreatable, with research and treatment strategies centred on slowing its progression by targeting amyloid plaques and tau tangles – abnormal protein accumulations in the brain. However, as these proteins often appear years before symptoms surface, some scientists have questioned whether they are the root cause or merely indicators of a more complex underlying process.
What can you do?
In recent years, a growing body of research has pointed to other potential contributing factors. A landmark 2020 Lancet Commission report on dementia prevention, intervention, and care highlighted a series of modifiable risk factors that may play a significant role in the onset of Alzheimer’s disease. These include excessive alcohol consumption, smoking, obesity, air pollution, poor diet, hypertension, diabetes, certain medications, physical inactivity, sleep disturbances, and social isolation. The report estimated that addressing these factors could prevent or delay up to 40 per cent of dementia cases worldwide.
This growing emphasis on prevention and lifestyle interventions signals a promising shift in dementia research. Scientists are now exploring alternative theories, such as the potential role of bacterial infections in triggering Alzheimer’s disease. While many questions remain unanswered, this evolving body of work offers fresh hope that advances in prevention, treatment – and ultimately a cure – may be closer than once believed.
With awareness on the rise, so too is the urgency to invest in research, expand public education, and provide meaningful support to the millions impacted by this devastating condition.
Let’s Talk Dementia
Let’s Talk Dementia is a community event in Byron Bay to raise awareness.

Attendees will gain a deeper understanding of dementia, practical strategies for care and support, and information on lifestyle changes that can help protect brain health. Whether you are living with dementia, caring for someone who is, or simply want to learn more, this event offers a welcoming space for conversation and connection.
Join the Let’s Talk Dementia event at the Byron Community Centre, 69 Jonson Street, Byron Bay on Thursday, April 10 from 6pm to 7:30pm. Tickets are $15 / $10 concession. For more information and tickets, visit events.humanitix.com/let-s-talk-dementia.
