Abstract

BACKGROUND: The differentiation of Alzheimer's disease (AD) from vascular dementia (VaD) is hampered by clinical diagnostic criteria with disappointing sensitivity and specificity. The objective of this study was to investigate whether cerebrospinal fluid (CSF) levels of total tau protein (t-tau), amyloid beta42 protein (Abeta42), and tau phosphorylated at threonine 181 (p-tau181) are useful biomarkers to distinguish AD patients from VaD patients. METHODS: We measured CSF levels of p-tau181, Abeta42, and t-tau in 86 patients with a clinical diagnosis of AD or VaD and in 30 control participants. RESULTS: Optimal differentiation between AD and VaD was achieved by using the ratio of the CSF levels of Abeta42 and p-tau181 (Q Abeta42/p-tau) with sensitivity, specificity, positive and negative predictive values all > or = 85%. CONCLUSIONS: Our results support further efforts to prospectively validate the use of Q Abeta42/p-tau as a biomarker to discriminate between AD and VaD.

  • The CSF tau/Aβ ratio is a powerful predictor of cognitive decline and can distinguish vascular dementia from Alzheimer's disease.

    “We hypothesized that CLU levels were also associated with CSF tau/Aβ ratio, a powerful predictor of cognitive decline that can be used to discriminate between vascular dementia and AD (de Jong, et al., 2006,Fagan, et al., 2007,Harari, et al., 2014)”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
