Join University of Sydney experts for fresh insights and evidence unlocking our understanding of healthy brain ageing. How might we all live – and stay – well, for longer, at any stage of life? Leading researchers at the Brain and Mind Centre are finding solutions for dementia, the second leading cause of death among all Australians and soon it will be the first, according to Dementia Australia. Neuroscientist Eleanor Drummond recently made some exciting headway in identifying proteins that are altered in the brain in the very first stages of Alzheimer’s disease and discovery of a new potential biomarker, and is currently working on translating this into the development of new drugs and biomarkers. Clinician and researcher Olivier Piguet specialises in frontotemporal dementia (FTD) and related younger-onset dementias. His successful intervention methods targeting behaviour and language have shown to improve quality of life and independence in patients and their families, reducing burden of care. Gilbert Knaggs is a researcher in sociology, and brings perspective on the ethics of dementia prevention, as well as concepts of ageing well and healthy ageing in society.

Is Australia still the Lucky Country? In public opinion polling, more and more Australians believe things are, on the whole, getting worse than better. Various data such as the longstanding Scanlon Social Cohesion Report point to society becoming polarised. A culture of suspicion continues to grow around our most important institutions, and loneliness and social isolation is common across our community. Against such concerning trends, what can be done? In this open discussion led by one of Australia’s foremost social researchers, author and University of Sydney alumna Dr Rebecca Huntley, we address three key, interconnected issues that will have a defining impact on national progress and prosperity, for generations to come. Featuring Dr Marlee Bower (Matilda Centre and Sydney Environment Institute), digital innovation expert Dr Raffaele F. Ciriello, refugee advocate and UN Women Australia MBA scholar ('24) Chantal Mousad, and economist Dr Suneha Seetahul (Australian Centre for Gender Equality and Inclusion at Work).
