Abstract

Mechanisms underlying phenotypic heterogeneity in young onset Alzheimer disease (YOAD) are poorly understood. We used diffusion tensor imaging and neurite orientation dispersion and density imaging (NODDI) with tract-based spatial statistics to investigate apolipoprotein (APOE) ε4 modulation of white-matter damage in 37 patients with YOAD (22, 59% APOE ε4 positive) and 23 age-matched controls. Correlation between neurite density index (NDI) and neuropsychological performance was assessed in 4 white-matter regions of interest. White-matter disruption was more widespread in ε4+ individuals but more focal (posterior predominant) in the absence of an ε4 allele. NODDI metrics indicate fractional anisotropy changes are underpinned by combinations of axonal loss and morphological change. Regional NDI in parieto-occipital white matter correlated with visual object and spatial perception battery performance (right and left, both p = 0.02), and performance (nonverbal) intelligence (WASI matrices, right, p = 0.04). NODDI provides tissue-specific microstructural metrics of white-matter tract damage in YOAD, including NDI which correlates with focal cognitive deficits, and APOEε4 status is associated with different patterns of white-matter neurodegeneration.

  • A post mortem AD study in humans revealed a decrease in NDI in the white matter of APOE4 carriers, suggesting a loss of axons.

    The Results report reduced white-matter NDI in APOE ε4-positive patients with young-onset Alzheimer’s disease relative to controls, and the Discussion interprets reduced NDI as modeling axonal loss. But this was a clinical MRI study, not a post-mortem study; the Discussion says post-mortem verification is needed. (LLM, conf=0.91)

  • In young-onset Alzheimer's disease, NDI is reduced in the parieto-occipital WM in both ε4+ and ε4- patients relative to controls, with the reduction more widespread in ε4+ patients.

    “With NODDI, (Slattery et al., 2017) reported reduced NDI in the parieto-occipital WM in both ε4+ and ε4-patients with young-onset Alzheimer's disease relative to controls, with the reduction more widespread in ε4+ patients.”

  • NODDI has improved sensitivity over DTI in young-onset Alzheimer's disease, with parallel reductions of NDI and ODI in some WM regions that had no observable changes in FA.

    “(Slattery et al., 2017) also demonstrated improved sensitivity of NODDI over DTI, reporting parallel reductions of NDI and ODI in some WM regions that had no observable changes in FA.”

  • NDI of the parieto-occipital WM is correlated with visuospatial and visuoperceptual cognitive performance in young-onset Alzheimer's disease.

    “NDI of the parieto-occipital WM was also correlated with visuospatial and visuoperceptual cognitive performance, a marker of parietal cortex function.”

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.
