  1. A minimally invasive dried blood spot biomarker test for the detection of Alzheimer's disease pathology

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Nature medicine 2026-01-05 Biomarkers

    Blood biomarkers have emerged as accurate tools for detecting Alzheimer's disease (AD) pathology, offering a minimally invasive alternative to traditional diagnostic methods such as imaging and cerebrospinal fluid (CSF) analysis.

  2. Development of thresholds and a visualization tool for use of a blood test in routine clinical dementia practice

    ✓ Peer-reviewed alzhub usefulness score 59 out of 100. Alzheimer's & dementia : the journal of the Alzheimer's Association 2024-08-03 Biomarkers

    Our multimarker blood test interpretation tool is ready for testing in real-world clinical dementia settings.

  3. Mitochondrial DNA abundance in blood is associated with Alzheimer's disease- and dementia-risk

    ✓ Peer-reviewed alzhub usefulness score 69 out of 100. Molecular psychiatry 2024-07-15 Biomarkers

    The mitochondrial cascade hypothesis of Alzheimer's disease (AD) has been portrayed through molecular, cellular, and animal studies; however large epidemiological studies are lacking.

  4. Blood Derived Amyloid Biomarkers for Alzheimer's Disease Prevention

    ✓ Peer-reviewed alzhub usefulness score 52 out of 100. The journal of prevention of Alzheimer's disease 2022-01-01 Biomarkers

    We also explored economic viability of using two different plasma amyloid assays for pre-screening in AD prevention trials and as routine clinical diagnostic tool, versus amyloid PET alone.

  5. Transitioning from cerebrospinal fluid to blood tests to facilitate diagnosis and disease monitoring in Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Journal of internal medicine 2021-06-26 Biomarkers

    Alzheimer's disease (AD) is increasingly prevalent worldwide, and disease-modifying treatments may soon be at hand; hence, now, more than ever, there is a need to develop techniques that allow earlier and more secure diagnosis.

  6. Neurofilament Light Chain in Cerebrospinal Fluid and Blood as a Biomarker for Neurodegenerative Diseases: A Systematic Review and Meta-Analysis

    ✓ Peer-reviewed alzhub usefulness score 72 out of 100. Journal of Alzheimer's disease : JAD 2019-01-01 Biomarkers

    In our study, in addition to PD, NFL was suggested to be a global diagnostic biomarker for neurodegenerative diseases.

  7. Altered levels of blood proteins in Alzheimer's disease longitudinal study: Results from Australian Imaging Biomarkers Lifestyle Study of Ageing cohort

    ✓ Peer-reviewed alzhub usefulness score 67 out of 100. Alzheimer's & dementia (Amsterdam, Netherlands) 2017-04-23 Biomarkers

    These data suggest that apoJ may have potential in the context of use (COU) of AD diagnostics, I-309 may be specifically useful in the COU of identifying individuals at greatest risk for progressing toward AD.

  8. Blood Beta-Amyloid and Tau in Down Syndrome: A Comparison with Alzheimer's Disease

    ✓ Peer-reviewed alzhub usefulness score 47 out of 100. Frontiers in aging neuroscience 2017-01-17 Biomarkers

    The Aβ-40 and tau levels were higher and the Aβ-42 level and Aβ-42/Aβ-40 ratio were lower in DS than in the controls (all p < 0.001).

  9. Differential levels of p75NTR ectodomain in CSF and blood in patients with Alzheimer's disease: a novel diagnostic marker

    ✓ Peer-reviewed alzhub usefulness score 40 out of 100. Translational psychiatry 2015-10-06 Biomarkers

    Alzheimer's disease (AD) is the primary cause of dementia in the elderly.

  10. Multiplex biomarkers in blood

    ✓ Peer-reviewed alzhub usefulness score 40 out of 100. Alzheimer's research & therapy 2013-06-25 Biomarkers

    Advances in the field of blood biomarker discovery will help in identifying Alzheimer's disease in its preclinical stage, allowing treatment to be initiated before irreversible damage occurs.
