Abstract

We surveyed a total of 570 cerebrospinal fluid (CSF) samples from a variety of diseases, including Alzheimer's disease (AD; n = 236), non‐AD‐demented and nondemented diseases (n = 239), and normal controls (n = 95) to quantitate levels of tau protein phosphorylated at serine 199 (CSF/phospho‐tau 199) by a recently established sandwich ELISA. The CSF/phospho‐tau 199 levels in the AD group were significantly elevated compared to those in all the other non‐AD groups. Receiver operating characteristics curves showed that the diagnostic sensitivity and specificity for the AD group versus all the other non‐AD groups using the CSF/phospho‐tau 199 were 85.2% and 85.0%, respectively. Furthermore, there was a significant positive correlation between CSF/phospho‐tau 199 and CSF/total‐tau levels in the AD group. Elevated CSF/phospho‐tau 199 in the AD group was noted irrespective of age, gender, dementia severity, and number of apolipoprotein E4 alleles. Thus, we suggest that CSF/phospho‐tau 199 may be a novel and logical biomarker in supporting antemortem diagnosis of AD.

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

  • Elevated CSF concentrations of total tau and tau phosphorylated at amino acids 181 and 217 are surprisingly AD-specific; tau-associated FTD subtypes do not have elevated CSF t-tau and p-tau concentrations, at least not to the levels present in AD.

    “It has been shown that elevated CSF concentrations of total tau (t‐tau) and tau phosphorylated at amino acids 181 and, more recently, 217 (p‐tau181 and p‐tau217, respectively) are surprisingly AD‐specific; tau‐associated FTD subtypes do not have elevated CSF t‐tau and p‐tau concentrations, 57 , 58 , 59 , 60 at least not to the levels present in AD.”

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.
