Australia's leading cause of death to change for the first time in decades

Australia is on the cusp of a significant shift in public health trends since the 1960s.

For decades, ischaemic heart disease has been the leading cause of death in the country.

However, recent data from the Australian Bureau of Statistics (ABS) indicated that this could change soon.


In 2023, ischaemic heart disease accounted for 9.2 per cent of all deaths.

However, dementia, including Alzheimer's disease, was a close second at 9.1 per cent.

'The latest data shows that there are now less than 250 deaths separating the top two leading causes,' ABS's Head of Mortality Statistics Lauren Moran stated.

This shift was more than just statistics; it also reflected profound changes in the society and healthcare system—both of which hold significant implications for how people approach health and ageing.

Dementia has been the leading cause of death for Australian women since 2016.

'Women have longer life expectancies than men and are more likely to live to an age when they have a heightened risk of developing dementia,' Ms Moran added.

Now, it is the leading cause of death in South Australia, the Australian Capital Territory, and, for the first time, New South Wales.


The increase in dementia-related deaths has been partly attributed to the success in combating heart disease.

The mortality rate for heart disease has decreased by nearly 90 per cent within 50 years, thanks to medical and healthcare advancements.

Yet, with increased longevity also came a higher risk of developing age-related conditions like dementia.

The mortality rate for dementia has skyrocketed by almost 850 per cent over the same period.

This stark increase became a wake-up call to prioritise brain health and support for patients affected by dementia.


About 421,000 Australians are currently living with dementia.

Dementia Australia's projections suggested that this number could double by 2054.

'As dementia edges closer to becoming the leading cause of death of Australians, we must act now to focus on the brain health of the nation as well as provide more targeted, effective support to those impacted by dementia,' Dementia Australia's CEO, Professor Tanya Buchanan, insisted.

As the nation's brain health becomes a priority, advocates started calling for more targeted and effective support for those impacted by dementia.

This includes better treatment options, increased funding for research, and enhanced care services for individuals and their families.

While dementia is on the rise, COVID-19—the third largest cause of death in 2022—fell to ninth place last year.

This drop reflected the success of vaccination campaigns and public health measures.

However, suicide remains the leading cause of premature death.

With over 3,000 lives lost to suicide, it's a stark reminder of the importance of mental health support and services across the country.

We encourage everyone to talk about brain health, seek regular medical advice, and support organisations that are working towards a future where dementia and other diseases no longer dominate our health landscape.

This article is really scary but working in mental health and supporting my friend with early onset dementia. The ‘help’ is always available statement is ironic. Help is available for educated, persistent and determined patient people who have advocates who understand the system. Having money helps. The paperwork, and privacy hoops to jump through are incredible, and at the end of the day, who is helping the affected person. It’s just shit!
 
My elder brother who I live with was diagnosed with delirium earlier this year and ended up spending 2 months in hospital....he has returned home and I am his official Carer. He is very fortunate that he is a Gold card holder with DVA ( Department of Veterans Affairs ) as he is a returned Vietnam veteran who suffers PTSD, because of this he is able to get home care and we have nurses visiting him three days per week. This helps immensely and helps relieve a bit of worry.....he is showing improvement since coming home to familiar surroundings and his delirium has eased somewhat mainly due to his medication....what the future holds for him is uncertain...it could lead to Dementia or Alzheimers in the longer term but for now he is far improved from his time in hospital. This came upon him very quickly in fact straight after us losing all in Cyclone Jasper at Christmas last year. The hospital doctors and his own GP suggest that this event may have been some sort of catalyst for his condition. Two weeks ago we lost our beloved 15 year old Jack Russell dog which was his ever loving companion....this set him back for sometime as his depression suddenly spiked again. He is better this week and I can only hope that he continues with his progress.

When autopsies are performed there is never the cause of death by parasites listed. Parasites are
endemic but don't tell anyone, horror of horrors. We all have parasites, from food, water, pets etc.
When these little critters take over it is silent and attributed to other diseases, liver, heart, dementia, and their toxins cause cancers too. Think about it!

MADE MY DAY,
Good on you, "Jest", keep going, girl. I certainly hope that I'm still here at your age with what I'm doing now.
The way you comment, I imagined that you'd be much younger.
No doubt, there'd be many of us who would have thought the same thing, about you. "Great".

Not surprised about heart disease being on the decline in the ratings. So much wonderful medical help. I
Meet people everyday who now have a pacemaker. Or an artificial
Valve. Sadly learnt today that Australia is not permitting a drug for dementia to be used here. If you are going to die or have a serious ailment why not try anything that might help.

Thank you Vicki for your kind words. You are so right about animals and the comfort they bring and become a cherished member of your Family. When they pass no matter how long you have had them it can be extremely devastating for their owners. My brother and myself are in that position now and miss our baby girl that has been with us for so long. Tomorrow she will be returned to us from the crematorium. We both are looking forward to her return. Love and thanks again. Pete.
