  1. Potential utility of plasma pTau217 for assessing amyloid and tau biomarker profiles

    ✓ Peer-reviewed alzhub usefulness score 76 out of 100. European journal of nuclear medicine and molecular imaging 2025-08-06 Biomarkers

    Plasma pTau217 is effective for predicting A/T biomarker profile and cognitive decline, though further study is needed to better explain its association with Aβ and tau PET staging.

  2. Use of a Blood Biomarker Test Improves Economic Utility in the Evaluation of Older Patients Presenting with Cognitive Impairment

    ✓ Peer-reviewed alzhub usefulness score 48 out of 100. Population health management 2024-03-28 Biomarkers

    More than 16 million Americans living with cognitive impairment warrant a diagnostic evaluation to determine the cause of this disorder.

  3. Utility of Blood-Based Tau Biomarkers for Mild Cognitive Impairment and Alzheimer's Disease: Systematic Review and Meta-Analysis

    ✓ Peer-reviewed alzhub usefulness score 71 out of 100. Cells 2023-04-18 Biomarkers

    This paper highlights the growing evidence that blood-based tau biomarkers have early diagnostic utility for Alzheimer's disease.

  4. Potential Utility of Plasma P-Tau and Neurofilament Light Chain as Surrogate Biomarkers for Preventive Clinical Trials

    ✓ Peer-reviewed alzhub usefulness score 74 out of 100. Neurology 2023-03-06 Biomarkers

    Plasma p-tau181/NfL can potentially be used to monitor large-scale population interventions in CU individuals.

  5. Predictive Utility of Plasma Amyloid and Tau for Cognitive Decline in Cognitively Normal Adults

    ✓ Peer-reviewed alzhub usefulness score 62 out of 100. The journal of prevention of Alzheimer's disease 2023-01-01 Biomarkers

    Plasma Aβ1-42 and t-tau levels have predictive utility for cognitive decline, even in subjects with normal cognition.

  6. Digital biomarkers and sex impacts in Alzheimer's disease management - potential utility for innovative 3P medicine approach

    ✓ Peer-reviewed alzhub usefulness score 67 out of 100. The EPMA journal 2022-06-06 Cognitive tests and assessment

    Digital biomarkers are defined as objective, quantifiable physiological and behavioral data that are collected and measured by means of digital devices.

  7. An update on the utility and safety of cholinesterase inhibitors for the treatment of Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 38 out of 100. Expert opinion on drug safety 2020-01-28 Treatments

    Alzheimer's disease (AD) is the most common cause of major neurocognitive disorders with a prevalence in the US of about 5.7 million in 2018.

  8. Potential utility of soluble p3-alcadein α plasma levels as a biomarker for sporadic Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 36 out of 100. Journal of Alzheimer's disease : JAD 2012-01-01 Biomarkers

    Alcadeins (Alcs) constitute a family of neuronal type I membrane proteins (α, β, γ) that share identical localization and function to the amyloid-β protein precursor (AβPP) in the brain.
