Importance Plasma phosphorylated tau (p-tau) has proven to be an accurate biomarker for
Alzheimer disease (AD) pathologic characteristics, offering a less expensive and less …

Blood‐based phosphorylated tau (Ptau) 181 and 217 biomarkers are sensitive and specific
for Alzheimer's disease. In this racial/ethnically diverse cohort study, participants were …

Abstract Objective Plasma phosphorylated‐tau‐181 (p‐tau181) reliably detects clinical
Alzheimer's disease (AD) as well as asymptomatic amyloid‐β (Aβ) pathology, but is …

Background Increasing evidence supports the use of plasma biomarkers of
neurodegeneration and neuroinflammation to screen and diagnose patients with dementia …

Background Phosphorylated tau (p-tau) epitopes in cerebrospinal fluid (CSF) are accurate
biomarkers for a pathological and clinical diagnosis of Alzheimer's disease (AD) and are …

Plasma phosphorylated tau181 (P-tau181) might be increased in Alzheimer's disease (AD),
but its usefulness for differential diagnosis and prognosis is unclear. We studied plasma P …

Background Plasma tau phosphorylated at threonine 217 (p-tau217) and plasma tau
phosphorylated at threonine 181 (p-tau181) are associated with Alzheimer's disease tau …

We examined whether plasma p-tau181 and p-tau217 are specific biomarkers of
pathologically confirmed Alzheimer's disease (AD). In particular, we investigated the utility of …

Importance There are limitations in current diagnostic testing approaches for Alzheimer
disease (AD). Objective To examine plasma tau phosphorylated at threonine 217 (P-tau217) …

Importance There is an urgent need for inexpensive and minimally invasive blood
biomarkers for Alzheimer disease (AD) that could be used to detect early disease changes …
