Dementia Australia wishes to acknowledge the generous contribution made by volunteers to the development of a blood test for Alzheimer’s disease following an announcement recently by The Florey Institute of Neuroscience & Mental Health.

Dementia Australia CEO Maree McCabe said that volunteers are the unsung heroes contributing to the success of studies, such as these, that aim to provide improved health and lifestyle outcomes for people impacted by dementia.

In this instance the 273 volunteers from Australia and Japan have shared their time for over ten years with either the Japanese National Centre for Geriatrics and Gerontology (NCGG) or the Australian Imaging, Biomarker and Lifestyle Study of Ageing (AIBL), the two studies on which the blood test was designed and then validated.

Christina Ratcliffe, an AIBL study participant in the cognitively healthy group, said that she is overjoyed by the results announced last week.

“My time in the study involved regular memory tests, brain scans and three lumbar punctures to detect amyloid indicators in the brain,” Ms Ratcliffe said.

“It feels great to have had made an impact on dementia research, and this easier and quicker test will be very welcome.”

“We are so grateful to the study participants. We want them to know that their contribution is genuinely making a difference. It is invaluable and it will have a lasting impact for generations to come,” Ms McCabe said.

“Volunteering for research is not just about drug testing and trials but also includes social research and in this study the collection and analysis of biomarkers over time.

“It would be wonderful if this inspires others to become involved in research.”

Professor Colin Masters, Laureate Professor of Dementia Research at the Florey Institute of Neuroscience and Mental Health and The University of Melbourne said the new blood test, although still in a research stage, is a game-changer for researchers and may allow clinicians to more easily detect Alzheimer’s disease and at a larger scale– an important step when conducting research.

“It is an honour to be working with the study participants and we would like to join Dementia Australia in acknowledging all the volunteers for their important contribution to dementia research,” Professor Masters said.
