Tóm tắt

AbstractIntroductionWe aimed to estimate the frequency of each AT(N) (β‐amyloid deposition [A], pathologic tau [T], and neurodegeneration [N]) profile in different clinical diagnosis groups and to describe the longitudinal change in clinical outcomes of individuals in each group.MethodsLongitudinal change in clinical outcomes and conversion risk of AT(N) profiles are assessed using linear mixed‐effects models and multivariate Cox proportional‐hazard models, respectively.ResultsParticipants with A+T+N+ showed faster clinical progression than those with A−T−N− and A+T±N−. Compared with A−T−N−, participants with A+T+N± had an increased risk of conversion from cognitively normal (CN) to incident prodromal stage of Alzheimer's disease (AD), and from MCI to AD dementia. A+T+N+ showed an increased conversion risk when compared with A+T±N−.DiscussionThe 2018 research framework may provide prognostic information of clinical change and progression. It may also be useful for targeted recruitment of participants with AD into clinical trials.
