revolutionary approach to cognitive testing that allows for an unprecedented number of performance features to be easily collected and mined for meaning. The results of this study indicate that DCTclock performance is associated with both gold-standard metrics of cognition (i.e., the PACC) and brain markers of amyloid and tau pathology amongst unimpaired older adults. The development and validation of such digitized measures may increase detection of subtle changes related to preclinical AD and more efficiently gather cognitive data through automated systems.
