By taking part in a CHeBA research study, you'll be partaking in world-leading research and making a valuable contribution to changing the future of dementia.


The MetMemory Study is a placebo-controlled study aiming to slow cognitive decline, using a safe medication used to treat diabetes and metabolic conditions.

Our aim is to slow loss of memory and other aspects of cognition with ageing, and examine whether metformin affects other aspects of metabolism, inflammation and the ageing process.

We're recruiting volunteers for a 3-year study.

Rethink My Drink

Rethink My Drink is a study led by researchers at UNSW Sydney's Centre for Healthy Brain Ageing and the University of Sydney to evaluate whether an online intervention is effective in helping older adults make healthier decisions about their alcohol consumption. The study examines whether the program helps to reduce risky alcohol consumption, cognitive decline and other alcohol-related harms and to improve quality of life.

We are seeking volunteer participants aged 60-75 years who regularly consume alcohol. All study activities are conducted remotely online. Volunteers can receive up to $60 in gift vouchers for their participation.

CogSCAN - Computerised Testing

This study aims to investigate how useful computerised tests can be, particularly in identifying cognitive impairment in older adults.

This world first study will examine whether they are as good as the tests typically administered face to face by a neuropsychologist.

To register, if you are aged 60 years and older, speak English fluently, and speak and/or read a language other than English you might be eligible to participate.

We are seeking volunteer participants for two opportunities, an online survey which can be completed anywhere in Australia, or a visit on-campus do some computerised cognitive (‘thinking’) tasks on a touch screen tablet computer (iPad) and also face-to-face.

Older Australian Twins Study (OATS)

OATS Twins

The Older Australian Twins Study is a longitudinal study investigating healthy brain ageing in older twins. Identical and non-identical twin pairs, aged 65 and older, living in Australia are eligible to participate in our research. With few exceptions, twin pairs can participate regardless of whether or not they are experiencing any memory or health problems. The online assessment includes answering questions about your health, lifestyle, memory and thinking and a neuropsychological assessment (the core aspect). Where feasible, participants will also be invited to provide a blood sample for analysis, and in some instances to have an MRI scan.
