Abstract

Increasing evidence demonstrates that there is marked damage and dysfunction not only in the gray matter but also in the white matter in Alzheimer's disease (AD). In this study, transgenic mice overexpressing beta-amyloid precursor protein (APP) under control of the platelet-derived growth factor promoter (PDAPP mice) were examined using diffusion tensor magnetic resonance imaging (DTI) to evaluate the extent of white matter injury before and following the development of AD-like pathology. The profile of DTI parameters was significantly different in old PDAPP mice compared to that of old control mice following the development of AD-like pathology. No difference in DTI parameters was observed between the young PDAPP and control mice. Our results suggest that as amyloid beta (Abeta) deposition and levels increase over time in PDAPP mice, these changes lead to primary or secondary white matter injury that can be detected by DTI.

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

  • The effects of amyloid plaques have been investigated in previous studies where differences in DTI parameters have been observed at late time points after the appearance of amyloid plaques.

    “The effects of amyloid plaques, the other hallmark pathology of AD, have been investigated in previous studies (Song et al., 2004, Sun et al., 2005) where differences in DTI parameters have been observed at late time points after the appearance of amyloid plaques.”

  • Degeneration could be initiated through synaptic or axonal mechanisms, independent of apoptosis.

    “These observations raise the prospect that degeneration could be initiated through synaptic or axonal mechanisms, independent of apoptosis, a mechanism which has been widely studied in other model systems, such as spinal cord injury and Multiple Sclerosis 59–61.”

  • The authors' dMRI results are generally consistent with those reported using other mouse models of AD.

    “Our dMRI results are generally consistent with those reported using other mouse models of AD [31–35].”

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.
