TRIAD multi‐dimensional biobank for biomarker discovery

The Translational Biomarkers in Aging and Dementia (TRIAD) is a longitudinal, biomarker‐based cohort designed to study interactions between the pathophysiological processes driving to dementia. Currently, 50 million people worldwide have dementia [1]. PET and MRI imaging have been widely used to assess disease stage, though expensive and not readily accessible [2]. More recently though, breakthroughs in blood‐based biomarkers have proven a useful, available, and more cost‐effective way of evaluating amyloid and tau positivity. The TRIAD Biobank provides a unique framework to study disease stage using blood‐based biomarkers in conjunction with PET and CSF studies. Our cohort allows for validation of novel biomarkers as we simultaneously acquire gold standard second generation imaging acquisitions with full spectrum fluid biomarkers (CSF, saliva, plasma, urine). Importantly, the data acquired is integrated in a database compliant to multi‐dimensional biomarker analysis.
