Abstract

As the global population continues to age, the prevalence of dementia-related illnesses is escalating at an unprecedented rate. This paper explores the intersection of demographic ageing, the inherent rise in dementia diagnoses, and the resulting strain on care systems, families, and government resources. The objective of this study is to critically examine projected trends in dementia prevalence, assess the economic burden on both individuals and public healthcare systems, and evaluate current service responses and policy frameworks in Australia. A mixed-methods approach was used, incorporating population health data, economic modelling, and literature review of policy documents and care outcomes. Quantitative projections indicate a doubling of dementia cases by 2050, with direct and indirect costs expected to exceed $25 billion annually in Australia alone. These figures include health care, aged care, and productivity losses, placing significant pressure on formal care systems and unpaid family carers. Our findings underscore that the current trajectory is unsustainable without substantial reform. Table 1 summarises projected dementia prevalence and cost implications by decade, while Figure 1 illustrates the proportional increase in care hours required per capita. Key recommendations include increased investment in community-based dementia care, integration of informal carers into health planning, and policy reform to strengthen workforce capacity. In conclusion, the ageing population is not only a health challenge but a complex socio-economic issue that demands coordinated, forward-thinking strategies. Urgent action is required to mitigate future costs and to support a quality care framework for those living with dementia and their families.
