Dementia overtakes heart disease as Australia's leading cause of death

Dementia has become Australia's leading cause of death, surpassing heart disease. The report indicates a significant rise in dementia deaths over the past decade, while heart disease fatalities have decreased. Mental health issues are also increasing, particularly among young people. Australians are living longer but spending more years in poor health. Chronic conditions are prevalent, with obesity now a greater risk factor for disease than smoking.
