Research led by Prof Tony Broe and Dr Kylie Radford has highlighted the high prevalence of dementia, particularly Alzheimer’s disease, in Aboriginal communities. We are working towards understanding the causes of cognitive decline and dementia, building capacity in dementia care and supporting Aboriginal family carers, and developing culturally appropriate strategies to promote healthy brain ageing.
The next decade will see a dramatic increase in the number and proportion of older people within the Aboriginal and Torres Strait Islander population. Close to 80% of these older people live in regional and urban parts of Australia (a third in our major cities). Recently, the Koori Growing Old Well Study (KGOWS) has shown that dementia prevalence in Aboriginal Australians across NSW is three times higher than the overall Australian population, at ages 60 years and older.
What is it that helps one person age successfully, and causes another to develop age-related diseases like dementia? Scientifically, we know too little about normal ageing and what factors influence some people, and not others, to develop diseases that affect the brain. Only by studying healthy elderly people, as well as those with problems, can we know what normal ageing looks like and learn more about staying healthy as we age. In collaboration with our Aboriginal community partners, our rigorous population- based approach allowed us to accurately assess the prevalence of dementia, not just those already ‘in the system’ and seeking treatment or care.
NeuRA’s Aboriginal health and ageing team, with collaborators, are now conducting a follow-up study (KGOWS-II) to determine the social and biomedical risk and protective factors for dementia across the lifespan. In 2016, NeuRA also initiated the Koori Active and Healthy Ageing Project. This research will develop effective, culturally appropriate, and accessible strategies to promote vitality and healthy brain ageing and prevent dementia in Aboriginal communities. This research is supported by NeuRA’s ongoing Koori Dementia Care Project, which aims to build capacity in dementia understanding and care with Aboriginal community controlled and mainstream service providers.
As one older Aboriginal participant observed: “Healthy ageing is your mind staying young”.
NeuRA researchers are stepping up their research with the introduction of a new perturbation treadmill aimed at preventing falls and improving balance. What is a perturbation treadmill? A perturbation treadmill is a treadmill, like those in the gym, but with two belts instead of one. We can control the speed of each belt independently. Each foot is placed on a […]
