A startling revelation has emerged from the land down under: Alzheimer's has claimed the top spot as Australia's leading cause of death in 2024, surpassing even heart disease. But is this shift a cause for concern or a natural progression?
According to the Australian Bureau of Statistics (ABS), dementia, primarily Alzheimer's disease, has taken a devastating toll, with 17,549 deaths in 2024 alone. This figure represents a staggering 160% increase from 2006, when dementia-related deaths were significantly lower. The data reveals a concerning trend, especially among the elderly, as 85.2% of these deaths occurred in individuals aged 75 and above, a 63.3% rise since 2004. This age group accounted for 16,620 dementia-related deaths in 2024.
But here's where it gets intriguing: women are disproportionately affected, making up a striking 62.4% of dementia-related deaths. This disparity can be attributed to women's generally longer life expectancy. Dementia has been the primary cause of death for Australian women since 2016, and the overall mortality rate from dementia has risen by 39% in the last ten years.
Looking ahead, the Australian Institute of Health and Welfare's report from September 2025 paints a challenging picture. They predict a dramatic increase in dementia cases, reaching 1 million by 2065, up from 425,000 in 2024. ABS officials also shed light on the complex health landscape, revealing that many dementia patients also suffer from coronary heart disease, hypertension, and certain types of cancer. The survey found that approximately 80% of dementia-related deaths had other diseases listed on the death certificate.
But the story doesn't end there. Ischaemic heart disease remains a formidable adversary, claiming over 16,000 lives in 2024 and ranking as the second-highest killer in Australia. Chronic lower respiratory diseases and cerebrovascular diseases also took a heavy toll, causing 9,229 and 9,147 deaths, respectively. ABS data further highlights mental and behavioral disorders as the fifth-biggest cause of mortality, with nearly 9,000 deaths. Interestingly, the leading cause of death varies by region, with dementia dominating in major cities and inner regional areas, while ischaemic heart diseases prevail in outer regional, remote, and very remote locations.
This article raises important questions about the future of healthcare in Australia and the world. Is the healthcare system adequately prepared for the increasing burden of dementia? How can we address the complex interplay of diseases that often accompany dementia? And what steps can be taken to reduce the impact of these devastating conditions?
