Canberra, Feb 5 (NationPress) The projected increase in the number of Australians under 65 affected by dementia is set to rise by 40% by the year 2054, based on new statistics released on Thursday.
The figures from Dementia Australia, the national organization dedicated to assisting individuals living with dementia and their families, indicate that the count of Australians estimated to have dementia has climbed to 446,500, an increase from 433,300 in 2025.
According to Dementia Australia, 29,000 Australians aged 18-65 are currently living with young-onset dementia, a number anticipated to surge by over 40% to approximately 41,000 by 2054.
Moreover, it is estimated that 1,500 children in Australia are diagnosed with childhood dementia.
Dementia emerged as the leading cause of death in Australia for the first time in 2024, constituting 9.4% of all fatalities, as per official statistics.
The Australian Institute of Health and Welfare (AIHW) highlighted in a report published in December that the figure of Australians living with dementia is projected to more than double to over one million by 2065.
Tanya Buchanan, the CEO of Dementia Australia, stated in a media release on Thursday that there is an urgent need for a national initiative aimed at promoting brain health and enhancing the quality of care and support services for individuals of all ages affected by dementia, according to the Xinhua news agency.
“Australia is globally recognized for its capabilities in dementia care, support, and research, yet the system still has areas requiring enhancement,” she remarked.
The organization has urged the federal government to launch a comprehensive brain health campaign, establish a national network of support services, and build workforce capacity to care for those living with dementia.
Dementia is a syndrome resulting from various diseases that progressively damage nerve cells and the brain, typically leading to a decline in cognitive function beyond what is normally expected from aging. While consciousness remains intact, cognitive decline is often accompanied, and sometimes preceded, by alterations in mood, emotional regulation, behavior, or motivation.
Point of View
It is our responsibility to highlight the rising prevalence of dementia in Australia, particularly among younger populations. With projections indicating a significant increase in cases, we must advocate for improved support and care systems to address this growing public health crisis.
