About the research project

In Australia, roughly 500,000 people are living with dementia, at a cost of around $15 billion per year. Roughly 40% of dementia cases could be prevented through modifiable risk factors, yet we are currently not intervening early enough in the disease spectrum. Tasmania has the highest median age of any Australian state or territory, and a high prevalence of chronic conditions that are also risk factors for dementia.

Language is a window into the brain. Recently, new evidence has shown how spoken language can reveal an individual’s cognitive status, and automated audio analysis of speech may offer cost-effective, accessible and scalable avenues to early detection of Alzheimer’s disease and other forms of dementia. This project will investigate the potential of speech analysis to detect the earliest signals of dementia, measured against validated blood-based biomarkers and cognitive tests that are biological and cognitive markers of dementia risk.

Using existing baseline data collected from ISLAND (Island Study Linking Ageing and Disease), a longitudinal study of roughly 14,000 Tasmanians over 50 years of age, this project will analyse how spoken language relates to cognitive and biological markers of dementia. It will also provide an opportunity for prospective data collection, and the development of a custom testing platform to administer a specific speech task the wider ISLAND cohort.
