Dementia Research

PREVALENCE OF DEMENTIA IN INDIGENOUS COMMUNITIES

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”.

FEEL THE BUZZ IN THE AIR? US TOO.

Ten siblings. One third live (or have passed away) with dementia.

The scourge of dementia runs deep in Lorna Clement's family. Of the eleven children her dear parents raised, four live (or have passed away) with complications of the disease. Her mother also died of Alzheimer's disease, bringing the family total to five. This is the mystery of dementia - One family, with two very different ageing outcomes. You will have read that lifestyle is an important factor in reducing the risk of dementia. We also know diet is a key factor, and an aspect that Dr Ruth Peter's is exploring at NeuRA. Along with leading teams delivering high profile evidence synthesis work in the area of dementia risk reduction, Dr Peters has a particular interest in hypertension (that is, high blood pressure) and in the treatment of hypertension in older adults. “We have known for a while that treating high blood pressure reduces the risk of cardiovascular disease and stroke, but it is becoming clearer that controlling blood pressure may also help to reduce the risk of cognitive decline and dementia. Now we need to know what the best blood pressure is to protect brain health.” You are invited to read more about Lorna's story and Dr Peter's work, by clicking 'Read the full story' below. Please support dementia research at NeuRA Will you consider a gift today to help Dr Peter's unlock the secrets of healthy ageing and reduce the risk of dementia? Research into ageing and dementia at NeuRA will arm doctors and other medical professionals with the tools they need to help prevent dementia in our communities. Thank you for your support.
