  1. Profiling Plasma Biomarkers, Particularly pTau217 and pTau217/Aβ42, and Their Relation to Cognition in Memory Clinic Patients

    ✓ Peer-reviewed alzhub usefulness score 57 out of 100. Journal of neurochemistry 2025-08-01 Biomarkers

    Alzheimer's disease (AD) is characterized by brain protein depositions, impaired synaptic transmission, and progressive cognitive decline.

  2. Association of plasma biomarkers of Alzheimer's disease and related disorders with cognition and cognitive decline: The MYHAT population-based study

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Alzheimer's & dementia : the journal of the Alzheimer's Association 2024-05-16 Biomarkers

    These relatively non-invasive tests may be beneficial for clinical screening after replication in other populations and validation through neuroimaging or cerebrospinal fluid analysis.

  3. Association of plasma biomarkers with cognition, cognitive decline, and daily function across and within neurodegenerative diseases: Results from the Ontario Neurodegenerative Disease Research Initiative

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Alzheimer's & dementia : the journal of the Alzheimer's Association 2023-12-17 Biomarkers

    GFAP, NfL, and p-tau181 are valuable predictors of cognition and function across common neurodegenerative diseases, and may be useful in specialized clinics and clinical trials.

  4. Associations between Plasma Biomarkers and Cognition in Patients with Alzheimer's Disease and Amnestic Mild Cognitive Impairment: A Cross-Sectional and Longitudinal Study

    ✓ Peer-reviewed alzhub usefulness score 59 out of 100. Journal of clinical medicine 2019-11-06 Biomarkers

    Brain degeneration in patients with Alzheimer's disease (AD) results from the accumulation of pathological amyloid- (Aβ) plaques and tau protein tangles, leading to altered plasma levels of biomarkers.

  5. Associations between Cerebrospinal Fluid Biomarkers and Cognition in Early Untreated Parkinson's Disease

    ✓ Peer-reviewed alzhub usefulness score 52 out of 100. Journal of Parkinson's disease 2015-01-01 Biomarkers

    The association between reduced CSF α-synuclein concentrations and cognition suggests that α-synuclein pathology contributes to early cognitive impairment in PD, in particular to executive-attentional dysfunction.

  6. Cellular, synaptic, and biochemical features of resilient cognition in Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 36 out of 100. Neurobiology of aging 2012-05-02 Biomarkers

    Although neuritic plaques and neurofibrillary tangles in older adults are correlated with cognitive impairment and severity of dementia, it has long been recognized that the relationship is imperfect, as some people exhibit normal cognition despite high levels of Alzheimer's disease (AD) pathology.
