Dementia-related deaths in Australia more than doubled between 2009 and 2024, according to the latest available data, making the condition one of the nation's most urgent public health issues. The peak body Dementia Australia warns that without significant intervention, more than 1 million Australians will be living with dementia by 2065.
Rising toll and long-term projections
The doubling of dementia deaths over the 15-year period reflects, in part, a population living longer. However, experts emphasize that age is not a cause of dementia, nor does age or improved screening fully explain the rise of a condition that remains complicated and difficult to treat.
Dementia is not a single illness. It can affect anybody, including children, though it is more common in those over 65. The condition is caused by more than 100 different illnesses and conditions, which complicates research into treatments. Alzheimer's disease, which itself has many types, is just one cause of dementia.
Varied symptoms and impact
Dementia may present with very different symptoms depending on the form. Some types affect speech, while others have a greater impact on memory, coordination, or the senses. Dementia is a major cause of disability and dependence among older Australians.
In 2026, an estimated 446,500 Australians are living with dementia. Dementia Australia is seeking input from those affected to guide a new series on living with dementia, focusing on the supports and awareness needed.
Seeking public input and support resources
Individuals living with dementia are encouraged to share their experiences to help shape the series. All questions are optional, and participation is voluntary.
For anyone with questions or concerns about dementia, the National Dementia Helpline is available at 1800 100 500, operating 24 hours a day, seven days a week. Additional information can be found through Dementia Australia.
