Abstract

Despite considerable interest in improving clinical and neurobiological characterisation of frontotemporal dementia and in defining the role of brain network disintegration in its pathogenesis, information about white matter pathway alterations in frontotemporal dementia remains limited. Here we investigated white matter tract damage using an unbiased, template‐based diffusion tensor imaging (DTI) protocol in a cohort of 27 patients with the behavioral variant of frontotemporal dementia (bvFTD) representing both major genetic and sporadic forms, in relation both to healthy individuals and to patients with Alzheimer's disease. Widespread white matter tract pathology was identified in the bvFTD group compared with both healthy controls and Alzheimer's disease group, with prominent involvement of uncinate fasciculus, cingulum bundle and corpus callosum. Relatively discrete and distinctive white matter profiles were associated with genetic subgroups of bvFTD associated with MAPT and C9ORF72 mutations. Comparing diffusivity metrics, optimal overall separation of the bvFTD group from the healthy control group was signalled using radial diffusivity, whereas optimal overall separation of the bvFTD group from the Alzheimer's disease group was signalled using fractional anisotropy. Comparing white matter changes with regional grey matter atrophy (delineated using voxel based morphometry) in the bvFTD cohort revealed co‐localisation between modalities particularly in the anterior temporal lobe, however white matter changes extended widely beyond the zones of grey matter atrophy. Our findings demonstrate a distributed signature of white matter alterations that is likely to be core to the pathophysiology of bvFTD and further suggest that this signature is modulated by underlying molecular pathologies.

  • Prior machine learning studies achieved moderate to high accuracy distinguishing bvFTD.

    “In general, they achieved moderate to high accuracy distinguishing bvFTD.”

    From MRI data-driven algorithm for the diagnosis of behavioural variant frontotemporal dementia (2021) · cites this paper as [10]

    The Results (Comparison of Diffusivity Metrics; page unavailable) report sensitivity and specificity ranging from moderate to high when distinguishing bvFTD from healthy controls or patients with Alzheimer’s disease. However, the paper reports its own diffusion-metric ROC analysis, not accuracy achieved by prior machine-learning studies. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Machine learning techniques have been applied to distinguish bvFTD from cognitively normal controls, Alzheimer Disease or other psychiatric and neurologic disorders on an individual level using MRI-based features.

    “Recently, machine learning techniques have been applied to distinguish between bvFTD and Cognitively Normal Subjects (CNCs), Alzheimer Disease or other psychiatric and neurologic disorders on an individual level using MRI-based features. 9-17”

    From MRI data-driven algorithm for the diagnosis of behavioural variant frontotemporal dementia (2021) · cites this paper as [10]

    The Methods section, “Sensitivity and Specificity of Diffusion Metrics in Predicting Group Membership” (page unavailable), describes ROC analysis of MRI-derived diffusivity metrics to classify individual participants as bvFTD, healthy controls, or Alzheimer’s disease. It does not describe a machine-learning technique or classification against other psychiatric or neurologic disorders. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Previous studies classified bvFTD from a control group.

    “Previous studies classified bvFTD from a control group. 9-13”
  • The cingulum is affected in many neurological conditions, including multiple sclerosis, Parkinson's disease, behavioural variant frontotemporal dementia, Mild Cognitive Impairment, and Alzheimer's disease.

    “The cingulum is affected in many neurological conditions, including multiple sclerosis, Parkinson’s disease, the behavioural variant of frontemporal dementia (Mahoney et al., 2014), Mild Cognitive Impairment (MCI), and Alzheimer’s disease (AD).”

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.
