Abstract

BACKGROUND: Apathy is the most common noncognitive symptom in Alzheimer's disease (AD). The structural correlates of apathy in AD have not yet been described. METHODS: We analyzed magnetic resonance imaging data of 35 AD patients with and without apathy. RESULTS: There was a significant linear association between apathy severity and cortical gray matter atrophy in the bilateral anterior cingulate [Brodmann area (BA) 24; r = 0.39-0.42, p = 0.01] and left medial frontal cortex (BA 8 and 9; r = 0.4, p < 0.02). Left mean cingulate cortical thinning predicted the presence/absence of apathy at the trend level of significance. CONCLUSION: Our study demonstrates a strong association between apathy and the integrity of medial frontal regions in AD.

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 volume loss in anterior cingulate cortex, including reduced gray matter volume and cortical thinning.

    “Structural imaging studies report volume loss in ACC, including reduced gray matter volume (Apostolova et al., 2007; Bruen et al., 2008; Stanton et al., 2013) and cortical thinning (Tunnard et al., 2011).”
  • Apathy in Alzheimer's disease is associated with volume loss and/or cortical thinning in frontal cortex.

    “There are also links between apathy and volume loss and/or cortical thinning in frontal cortex (Apostolova et al., 2007; Bruen et al., 2008; Stanton et al., 2013; Tunnard et al., 2011), though there is no strict concordance on the specific regions of frontal cortex which include medial, lateral, and orbital regions.”

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.
