These counts and lists are worked out from the library itself each time the page loads. A score rates how much weight a study can bear — its design, journal, evidence and recency — not whether its result is good news. How we score a study.

The 20 highest-scoring studies

  1. Brain MRI signatures across sex and CSF Alzheimer's disease biomarkers Brain communications · 2025-05-30 · · Peer-reviewed
  2. CSF biomarker concordance with amyloid PET in Phase 3 studies of aducanumab Alzheimer's & dementia : the journal of the Alzheimer's Association · 2023-02-16 · · Peer-reviewed
  3. Sex Differences in Apolipoprotein E and Alzheimer Disease Pathology Across Ancestries JAMA network open · 2025-03-03 · · Peer-reviewed

    This meta-analysis examined how the APOE gene, sex and ancestry relate to three core CSF Alzheimer's biomarkers. It is about understanding risk and biomarker patterns across groups, not about treating or preventing Alzheimer's.

  10. Diagnostic performance and prediction of clinical progression of plasma phospho-tau181 in the Alzheimer’s Disease Neuroimaging Initiative Molecular psychiatry · 2020-07-16 · · Peer-reviewed
  11. Slowing gait speed precedes cognitive decline by several years Alzheimer's & dementia : the journal of the Alzheimer's Association · 2022-02-09 · · Peer-reviewed
  12. Association between CSF biomarkers of Alzheimer's disease and neuropsychiatric symptoms: Mayo Clinic Study of Aging Alzheimer's & dementia : the journal of the Alzheimer's Association · 2022-02-09 · · Peer-reviewed
  13. Association of white matter hyperintensities with cognitive decline and neurodegeneration Frontiers in aging neuroscience · 2024-09-12 · · Peer-reviewed
  14. Association of Altered Liver Enzymes With Alzheimer Disease Diagnosis, Cognition, Neuroimaging Measures, and Cerebrospinal Fluid Biomarkers JAMA network open · 2019-07-03 · · Peer-reviewed

    This cohort study examined whether blood markers of liver function are associated with cognitive dysfunction and with amyloid, tau, and neurodegeneration biomarkers for Alzheimer disease. It reports associations only and does not show that any liver-related treatment, cure, or prevention works.

  15. Increased Medial Temporal Tau Positron Emission Tomography Uptake in the Absence of Amyloid-β Positivity JAMA neurology · 2023-10-01 · · Peer-reviewed

    This study examined the course of medial temporal tau deposition seen on PET in older individuals without amyloid-beta pathology and its link to Alzheimer's disease. It is an observational cohort study and does not test any treatment, cure, or prevention.

  16. Core CSF Biomarker Profile in Cerebral Amyloid Angiopathy: Updated Meta-Analysis Neurology · 2024-09-13 · · Peer-reviewed

    This meta-analysis compared five core cerebrospinal fluid biomarkers in people with sporadic cerebral amyloid angiopathy versus controls and/or patients with Alzheimer disease. It is about characterizing biomarkers of cerebral amyloid angiopathy, not about treating, curing or preventing Alzheimer disease.

  17. Progression of Subjective Cognitive Decline to MCI or Dementia in Relation to Biomarkers for Alzheimer Disease: A Meta-analysis Neurology · 2022-08-26 · · Peer-reviewed

    This meta-analysis examined whether people with subjective cognitive decline who have Alzheimer's disease biomarkers are more likely to progress to mild cognitive impairment or dementia. It is a review of observational studies and does not test any treatment, cure, or prevention.

  18. Liver-Specific Polygenic Risk Score Is Associated with Alzheimer's Disease Diagnosis Journal of Alzheimer's disease : JAD · 2023-01-01 · · Peer-reviewed
  19. Association of Extracellular Vesicle Biomarkers With Alzheimer Disease in the Baltimore Longitudinal Study of Aging JAMA neurology · 2019-11-01 · · Peer-reviewed

    This case-control study tested whether markers in plasma neuronal-enriched extracellular vesicles could predict Alzheimer disease in cognitively normal participants who later developed it. It is a validation study of a blood-based predictor, not a treatment, cure, or prevention.

  20. Relevance of Minor Neuropsychological Deficits in Patients With Subjective Cognitive Decline Neurology · 2023-10-11 · · Peer-reviewed

    In people with subjective cognitive decline, minor deficits on neuropsychological tests were related to Alzheimer's CSF biomarkers and progression to mild cognitive impairment. This may help identify who is at higher risk earlier, but it does not test a treatment or prevention.
