A Head-to-Head Comparison Between Plasma pTau181 and Tau PET Along the Alzheimer’s Disease Continuum

Abstract

Both plasma tau phosphorylated at threonine-181 (pTau181) and tau positron emission tomography (tau-PET) show potential for detecting Alzheimer's disease (AD) pathology and predicting clinical progression. In this study, we performed a head-to-head comparison between plasma pTau181 and tau-PET along the AD continuum.
