Topic: Amyloid, tau and blood-test diagnosis

Plain-language summary

During the past decade, a conceptual shift occurred in the field of Alzheimer's disease (AD) considering the disease as a continuum. Thanks to evolving biomarker research and substantial discoveries, it is now possible to identify the disease even at the preclinical stage before the occurrence of the first clinical symptoms. This preclinical stage of AD has become a major research focus as the field postulates that early intervention may offer the best chance of therapeutic success. To date, very little evidence is established on this "silent" stage of the disease. A clarification is needed about the definitions and lexicon, the limits, the natural history, the markers of progression, and the ethical consequence of detecting the disease at this asymptomatic stage. This article is aimed at addressing all the different issues by providing for each of them an updated review of the literature and evidence, with practical recommendations.

What this study adds

Evidence grade: Not rated

Reviews the evidence on preclinical Alzheimer's disease, the stage before symptoms appear, covering definitions, natural history, markers of progression and the ethics of detecting the disease at this stage. It offers practical recommendations.

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on strength of evidence, so that was left out: it earned 56 of the 95 points we could judge it on, which is 59 out of 100.
