Abstract

Background Tau and beta-amyloid (Abeta) are proposed diagnostic biomarkers for Alzheimer disease (AD). Previous studies report their relationship to clinical diagnoses of AD and other dementias. To understand their value as predictors of disease-specific pathology, levels determined during life must be correlated with definitive diagnoses in mixed dementia groups and cognitively normal subjects. Objectives To correlate antemortem cerebrospinal fluid (CSF) tau and Abeta levels with definitive dementia diagnosis in a diverse group of patients; to calculate statistics for CSF tau and Abeta. Design Prospective study. Setting Ten clinics experienced in the diagnosis of neurodegenerative dementias. Patients One hundred six patients with dementia and 4 cognitively normal subjects with a definitive diagnosis, and 69 clinically diagnosed cognitively normal subjects. Main outcome measures Correlation of CSF tau and Abeta with final diagnosis. Results Mean tau level was 612 pg/mL for the 74 patients with AD, 272 pg/mL for 10 patients with frontal dementia, 282 pg/mL for 3 patients with dementia with Lewy bodies, and 140 pg/mL for 73 cognitively normal control subjects. Tau was less than 334 pg/mL for 20 patients with AD. Abeta42 was reduced in patients with AD (61 fmol/mL) compared with patients with frontal dementia (133 fmol/mL) and control subjects (109 fmol/mL), but not compared with patients with dementia with Lewy bodies (14 fmol/mL) or prion disease (60 fmol/mL). Conclusions Elev…

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Low concentrations of Aβ42 in the CSF reflect the presence of cerebral Aβ deposition, likely as a result of Aβ42 being sequestered into amyloid plaques, changing the equilibrium between the brain and CSF pools of Aβ.

    “low concentrations of Aβ42 in the cerebrospinal fluid (CSF) reflect the presence of cerebral Aβ deposition, likely as a result of Aβ42 being sequestered into amyloid plaques, changing the equilibrium between the brain and CSF pools of Aβ (20-22).”

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.
