Reduction of orbital frontal cortex volume in geriatric depression

Abstract

Background Postmortem studies have documented abnormalities in the medial orbital frontal cortex in depressed patients. In this study we evaluated whether atrophy of this region can be identified in older depressed patients using magnetic resonance imaging. Methods Twenty elderly patients meeting DSM-IV criteria for major depression and 20 matched control subjects were studied. The orbital frontal cortex was measured in both hemispheres using magnetic resonance imaging. Results Depressive patients had reduced volume in the total orbital frontal cortex, right orbital frontal cortex, and left orbital frontal cortex. Conclusions Our finding of a reduction in orbital frontal cortex volume in both sides of the brain suggests that this region of the brain may have a critical role in the development of depression and raises questions about the etiology of the changes.

  • Abnormal pathological dysfunctions, defects and alterations in these brain regions are significantly related to multiple psychiatric and mental health disorders, including depression and aggression.

    “abnormal pathological dysfunctions/defects and alterations in these brain regions are significantly related to multiple psychiatric and mental health disorders (Lai, Payne, Byrum, Steffens, & Krishnan, 2000; Tamminga & Buchsbaum, 2004; van Heukelum et al., 2021), including depression (Lai et al., 2000), and aggression (van Heukelum et al., 2021)”

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.
