The Australian Imaging Biomarkers and Lifestyle (AIBL) study

The Australian Imaging, Biomarker and Lifestyle (AIBL) study aims to investigate the natural history of Alzheimer’s disease (AD), from preclinical onset to development of dementia. The study collects biospecimens, brain images and clinical and cognitive data into its databank with the aim to discover which biomarkers, cognitive characteristics, and health and lifestyle factors predict development and progression of symptomatic AD.

Lifestyle data is also collected on AIBL participants, with an aim to find modifiable risk factors for disease onset and progression. Furthermore, disease onset and rates of change are investigated using extensive genetic datasets.


  • Investigate the natural history of Alzheimer’s disease, from preclinical onset to development of dementia.
  • Investigate biofluid test for diagnostic purposes.
  • Explore changes in hallmark pathologies within the brain environment using new PET tracers.

AIBL launched 14 November 2006 and is the largest study of its kind in Australia.

  • 15+ year prospective longitudinal study of cognition.
  • Large-scale cohort study: 3000+ participants (minimum age 50 years).
  • Participants with AD, mild cognitive impairment (MCI) and healthy volunteers.
  • Focus on early detection, towards lifestyle interventions.
  • All data is collected at two centres (40% subjects from Perth in Western Australia, 60% from Melbourne, Victoria).
  • Techniques used include diagnostics and imaging (PET, MRI).
  • A multidisciplinary research team is drawn from partner organisations in Perth, Sydney, Adelaide, Melbourne, Canberra and Brisbane.

The AIBL study has validated PET tracers to reveal the 30-year time scale of amyloid plaque accumulation in the brain in AD, and has supported development of cerebrospinal fluid (CSF) assays, culminating in receiving NATA accreditation to run the Roche Elecsys immunoassay for Amyloid beta 1-42, Phospho-tau and Total tau in CSF for Alzheimer’s disease. Now AIBL is looking for a less invasive and cheaper biofluid test for diagnostic purposes, for aiding disease staging, and for investigating underlying biochemical changes as potential therapeutic or diagnostic targets. Additionally, the AIBL study is introducing new PET tracers to investigate changes in hallmark pathologies within the brain environment.
