  1. Alzheimer's disease neuropathology plasma biomarkers and cognition in midlife: a community-based cohort study

    ✓ Peer-reviewed alzhub usefulness score 74 out of 100. Lancet (London, England) 2026-05-01 Biomarkers

    Alzheimer's disease neuropathology positivity was present in 86 (6%) participants based on p-tau217/Aβ42, 196 (15%) based on Aβ42/40, and 48 (4%) based on p-tau217, and was associated with worse performance on processing speed (standardised cognitive difference comparing Alzheimer's disease neuropathology positive to negative for Aβ42/40, p-tau217, and p-tau217/Aβ42 -0·54 to -0·25; p values 0·0001 to 0·0048) and executive function (-0·42 to -0·19; p values 0·0070 to 0·049).

  2. Evaluation of plasma p-tau217 for detecting amyloid pathology in a heterogeneous community-based cohort

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Alzheimer's & dementia : the journal of the Alzheimer's Association 2025-07-01 Biomarkers

    Plasma p-tau217 is an accurate indicator of amyloid pathology in a heterogeneous cohort and is superior to other plasma biomarkers assessed.

  3. Characterization of plasma AT(N) biomarkers among a racial and ethnically diverse community-based cohort: an HABS-HD study

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Alzheimer's & dementia (New York, N. Y.) 2025-01-01 Biomarkers

    Our findings indicate differential relationships between comorbidities (demographic, medical, diagnostic) across NHB, Hispanic, and NHW participants.

  4. The impact of kidney function on plasma neurofilament light and phospho-tau 181 in a community-based cohort: the Shanghai Aging Study

    ✓ Peer-reviewed alzhub usefulness score 45 out of 100. Alzheimer's research & therapy 2024-02-12 Biomarkers

    Considering renal function and age is crucial when interpreting AD biomarkers in the general aging population.
