WebAlzheimer's disease (AD) is as a continuum entailing a preclinical phase, where individuals are cognitively unimpaired but amyloid-β (Aβ) and tau pathology have begun, followed by a clinical phase (including mild cognitive impairment and dementia). In the preclinical Alzheimer stage, Aβ and tau progressively accumulate over 2 decades or more. On top … WebConclusive development of potential disease-modifying treatments for preclinical AD may still need confirmation of AD through robustly validated biomarkers, such as CSF and PET. 31 We noted that in the unselected analysis, the predictive performance of plasma P-tau231 had improved compared with its performance in the main analysis, in which it ...
