As many Australians start the year with a New Year’s resolution to increase their physical activity, Dementia Australia is cheering them on. Physical inactivity is the nation’s largest contributing modifiable risk factor for dementia – a significant motivation to get active in the new year.
A 2023 study [1] found that in Australia, physical inactivity was the largest modifiable risk factor for developing dementia – exceeding smoking, alcohol consumption and traumatic brain injury.
Additionally, in 2024, the Dementia Lancet Commission reported that midlife physical inactivity is a risk factor for dementia [2] .
Dementia Australia CEO Professor Tanya Buchanan said it is vital Australians know the importance of being physically active, not only for their bodies, but their brains too.
“A sedentary lifestyle or low levels of physical activity has consistently been linked to an increased risk for neurodegenerative diseases, including dementia,” Professor Buchanan said.
“Dementia Australia is calling on the Australian Federal Government to fund a national discussion about brain health and how to lower our dementia risk – including getting physically active.
“In the meantime, it is important that Australians of all ages know the importance of being active. The Dementia Australia library has information and tips for being physically active both before and after a dementia diagnosis.”
Dementia Australia Dementia Advocate Heather Cooper, who lives with dementia, enjoys the benefits of regular movement as someone who exercises multiple times a week at age 80.
“I run four times a week,” Heather said.
“The other two days I do cross training and then I have a rest on one day. The community bus takes us once a week to where there's a pool, so I swim a kilometre there.
“And of course, I walk every day!
“I really structure my exercise around keeping my body really limber and looking after it in every way.”
For those looking for a way to get active in the new year consider getting involved in Dementia Australia’s largest annual fundraising event – Memory Walk & Jog. With 28 events running across the country in 2025, Memory Walk & Jog is a great way to get active and raise funds in support of people impacted by dementia.
