Abstract

Objectives To identify regional alterations of white matter integrity associated with apathy in Alzheimer disease (AD).Design Cross-sectional study.Setting University Dementia Clinic.Participants Fifty-one very mild or mild probable AD subjects.Intervention Volumetric magnetic resonance imaging with diffusion tensor imaging.Measurements Volume of interest analyses were performed to compare regional fractional anisotropy (FA) between apathy and apathy-free group, and to test linear relationship between regional FA and apathy severity. Apathy was assessed by the Neuropsychiatric Inventory.Results Apathy group showed significantly lower FA values than apathy-free group in the left anterior cingulum (A-C), regardless of concomitant depression and psychotropic medications. Left A-C FA values also had significant linear relationship with apathy-composite scores as a measure of apathy severity, even after controlling gray matter density of the ipsilateral anterior cingulate cortex.Conclusions Our findings support that communication failure between the anterior cingulate cortex and other brain structures via the A-C contributes to the development and aggravation of apathy in AD, additionally supporting the general notion of disconnection syndrome for clinical manifestation of AD.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

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?

  • Apathy in Alzheimer's disease is associated with decreased anterior cingulate cortex white matter integrity by diffusion tensor imaging.

    “Similarly apathy is associated with decreased perfusion in ACC (Benoit et al., 2004; Lanctôt et al., 2007; Robert et al., 2006), decreased ACC white matter integrity by DTI (Hahn et al., 2013; Kim et al., 2011; Ota et al., 2012) and increased amyloid burden in right ACC (Mori et al., 2014).”

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.
