Abstract

Pattern of diffusion tensor MRI (DTI) alterations were investigated in pathologically-staged Alzheimer's disease (AD) patients (n = 46). Patients with antemortem DTI studies and a range of AD pathology at autopsy were included. Patients with a high neurofibrillary tangle (NFT) stage (Braak IV-VI) had significantly elevated mean diffusivity (MD) in the crus of fornix and ventral cingulum tracts, precuneus, and entorhinal white matter on voxel-based analysis after adjusting for age and time from MRI to death (p < 0.001). Higher MD and lower fractional anisotropy in the ventral cingulum tract, entorhinal, and precuneus white matter was associated with higher Braak NFT stage and clinical disease severity. There were no MD and fractional anisotropy differences among the low (none and sparse) and high (moderate and frequent) β-amyloid neuritic plaque groups. The NFT pathology of AD is associated with DTI alterations involving the medial temporal limbic connections and medial parietal white matter. This pattern of diffusion abnormalities is also associated with clinical disease severity.

  • A combined ante-mortem DTI and post-mortem histochemical analysis in cognitively normal participants found amyloid and tau pathology to be associated with ante-mortem DTI alterations selectively in the medial temporal and parietal white matter.

    “In a similar vein, a combined ante-mortem DTI and post-mortem histochemical analysis in brains from cognitively normal participants found amyloid and tau pathology to be associated with ante-mortem DTI alterations selectively in the medial temporal and parietal white matter (Kantarci et al., 2017).”

  • The observed pattern of decreased FA and increased MD, RD, and AD in P301L mice is in good agreement with DTI changes observed in human tauopathies such as progressive supranuclear palsy, frontotemporal dementia, mild cognitive impairment, and Alzheimer's disease.

    “In this regard, the observed pattern of decreased FA and increased MD, RD, and AD values in P301L mice in the current study are in good agreement with DTI changes observed in human tauopathies such as progressive supranuclear palsy [21], frontotemporal dementia [22], mild cognitive impairment [24], and Alzheimer`s disease [18,25].”

    From Diffusion tensor imaging reveals whole-brain microstructural changes in the P301L mouse model of tauopathy. (2020) · cites this paper as [21]

    The Results (section 3.3) and Discussion (section 4) report higher MD and lower FA in specific white-matter regions with more advanced Alzheimer’s pathology, supporting the Alzheimer’s disease comparison. The paper does not report increased RD or AD, so it does not support the full four-measure pattern attributed to the human findings. The other named conditions have separate citations in the citing sentence. (LLM, conf=0.88)

  • DTI is a powerful noninvasive method widely used for detecting brain microstructural abnormalities associated with Alzheimer's disease.

    “DTI is a powerful noninvasive method widely used for detecting brain microstructural abnormalities associated with AD (Kantarci et al., 2017; Falangola et al., 2020; Bergamino et al., 2023).”
  • Based on previous findings and preliminary data, no significant asymmetry in DTI measures at any timepoints was expected in untreated mice.

    “Based on previous findings and preliminary data, we did not expect to see any significant asymmetry in DTI measures at any timepoints in untreated mice 29.”

    From Amyloid-beta induced retrograde axonal degeneration in a mouse tauopathy model (2019) · cites this paper as [29]

    The Introduction describes a study of DTI and Alzheimer’s pathology in older adults; its mention of a mouse model concerns myelin loss, not asymmetry. Searches for asymmetry, untreated or control mice, and longitudinal DTI measures found no passage addressing the cited expectation. No page numbers are available in our copy. (LLM, conf=0.76)

  • Previous work from the authors' lab found no axonal damage in the optic tract or optic nerves after Aβ injection into the LGN of wild type mice.

    “Our lab previously has explored the degeneration induced by an Aβ injection in LGN of wild type mice, and we did not find axonal damage in optic tract or optic nerves 29”

    From Amyloid-beta induced retrograde axonal degeneration in a mouse tauopathy model (2019) · cites this paper as [29]

    The Introduction describes a study of DTI findings in older adults followed to autopsy, not Aβ injections in wild-type mice. Searches for LGN injections, optic tracts, optic nerves, and axonal damage found no passage in our copy reporting the claimed experiment or its result. (LLM, conf=0.76)

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.
