Abstract

INTRODUCTION: Individuals in early stages of Alzheimer's disease are a targeted population for secondary prevention trials aimed at preserving normal cognition. Understanding within-person biomarker(s) change over time is critical for trial enrollment and design. METHODS: Longitudinal cerebrospinal fluid samples from the Alzheimer's Disease Neuroimaging Initiative were assayed for novel markers of neuronal/synaptic injury (visinin-like protein 1, Ng, and SNAP-25) and neuroinflammation (YKL-40) and compared with β amyloid 42, tau, and phospho-tau181. General linear mixed models were used to compare within-person rates of change in three clinical groups (cognitively normal, mild cognitive impairment, and Alzheimer's disease) further defined by β amyloid status. RESULTS: Levels of injury markers were highly positively correlated. Despite elevated baseline levels as a function of clinical status and amyloid-positivity, within-person decreases in these measures were observed in the early symptomatic, amyloid-positive Alzheimer's disease group. DISCUSSION: Knowledge of within-person biomarker change will impact interpretation of biomarker outcomes in clinical trials that are dependent on disease stage.

  • At the time of tau positivity, during neurodegeneration and cognitive abnormalities phases, CSF p-tau epitopes have largely reached a plateau.

    “At the time of tau positivity, during neurodegeneration and cognitive abnormalities phases, CSF p-tau epitopes have largely reached a plateau.66”

    From Cerebrospinal fluid p-tau231 as an early indicator of emerging pathology in Alzheimer's disease (2022) · cites this paper as [66]

    The Discussion reports no statistically significant change in CSF pTau in amyloid-positive MCI, which is consistent with a plateau during that early symptomatic stage. But the Results (Elecsys pTau; page not provided) report a significant decline in the AD+ group, not a plateau across the later cognitive-abnormality phase. The paper also does not establish when pTau first becomes positive. (LLM, conf=0.84)

  • Neurogranin, synaptogamin, and SNAP-25 are the strongest candidates for in vivo tracking of synaptic homeostasis.

    “Neurogranin (a key regulator of the calcium-binding protein calmodulin), synaptogamin (a calcium sensor protein), and SNAP-25 (a component of the SNARE [soluble N-ethylmaleimide sensitive factor attachment protein receptor] complex) are the strongest candidates for in vivo tracking synaptic homeostasis (131–133).”

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.
