Abstract

We investigated patterns of white matter (WM) loss in 18 early onset (EO) and 24 late onset (LO) Alzheimer's disease (AD) patients compared with 42 healthy controls (HC), and explored relationships of WM atrophy and apolipoprotein E (ApoE) genotype. Subjects underwent magnetic resonance imaging (MRI). Patterns of WM were assessed using voxel-based morphometry. Compared with healthy controls, LOAD patients had a selective parahippocampal WM loss, while EOAD patients experienced a more widespread pattern of posterior WM atrophy. The distinct regional distribution of WM atrophy reflected the topography of gray matter (GM) loss. ApoE ε4 status was associated with a greater parahippocampal WM loss in both AD groups. The greater WM atrophy in EOAD than LOAD fits with the evidence that EOAD is a more aggressive form of the disease. The ApoE ε4 effect on WM damage in AD is restricted to specific WM regions and does not seem to be related to age of onset.

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.

Claims other papers make about this one

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

  • EOAD patients tend to show widespread cortical atrophy even in the early stage, especially in the posterior parietal and lateral temporal cortices, with relatively less involvement of the medial temporal structures.

    “EOAD patients tend to show widespread cortical atrophy even in the early stage, especially in the posterior parietal and lateral temporal cortices, with relatively less involvement of the medial temporal structures (Frisoni et al., 2005, 2007; Canu et al., 2012; Cho et al., 2013a).”

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.
