  1. Blood-based biomarkers for Alzheimer's disease: influence of kidney function

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Alzheimer's research & therapy 2026-02-02 Biomarkers

    KD was associated with higher plasma concentrations of p-Tau217, p-Tau181, Aβ42, Aβ40, and NfL, not with the Aβ42/Aβ40 ratio.

  2. Kidney Function and Blood and Cerebrospinal Fluid Biomarkers in Alzheimer's Disease and Related Dementias: Systematic Review and Meta-Analysis

    ✓ Peer-reviewed alzhub usefulness score 86 out of 100. Journal of the American Society of Nephrology : JASN 2026-01-26 Biomarkers

    Key points Lower kidney function is associated with higher concentrations of blood biomarkers for Alzheimer's disease and related dementia.

  3. 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.

  4. Influence of kidney function and CSF/serum albumin ratio on plasma Aβ42 and Aβ40 levels measured on a fully automated platform in patients with Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 50 out of 100. Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology 2023-06-07 Biomarkers

    Plasma Aβ42 and Aβ40 are critically influenced by kidney function; however, their ratio is advantageously spared from this effect.
