Whole brain resting-state analysis reveals decreased functional connectivity in major depression

Abstract

Recently, both increases and decreases in resting-state functional connectivity have been found in major depression. However, these studies only assessed functional connectivity within a specific network or between a few regions of interest, while comorbidity and use of medication was not always controlled for. Therefore, the aim of the current study was to investigate whole-brain functional connectivity, unbiased by a priori definition of regions or networks of interest, in medication-free depressive patients without comorbidity. We analyzed resting-state fMRI data of 19 medication-free patients with a recent diagnosis of major depression (within 6 months before inclusion) and no comorbidity, and 19 age- and gender-matched controls. Independent component analysis was employed on the concatenated data sets of all participants. Thirteen functionally relevant networks were identified, describing the entire study sample. Next, individual representations of the networks were created using a dual regression method. Statistical inference was subsequently done on these spatial maps using voxel-wise permutation tests. Abnormal functional connectivity was found within three resting-state networks in depression: (1) decreased bilateral amygdala and left anterior insula connectivity in an affective network, (2) reduced connectivity of the left frontal pole in a network associated with attention and working memory, and (3) decreased bilateral lingual gyrus connectivity within ventromedial visual regions. None of these effects were associated with symptom severity or gray matter density. We found abnormal resting-state functional connectivity not previously associated with major depression, which might relate to abnormal affect regulation and mild cognitive deficits, both associated with the symptomatology of the disorder.

  • Other studies in major depressive disorder reported decreased functional connectivity between more dorsal areas of the frontolimbic network compared with subcortical and limbic areas.

    “Conversely, other studies in MDD reported decreased functional connectivity between more dorsal areas of the frontolimbic network compared with subcortical and limbic areas within the frontolimbic (57,60-62).”
  • Abnormal resting-state functional connectivity of the primary visual area, including the occipital cortex and calcarine gyrus and extending into the lingual gyrus, has been reported previously.

    “The abnormality of the restingstate functional connectivity related to the primary visual area, including the occipital cortex and calcarine gyrus and extending into the lingual gyrus, has been reported before (Veer et al., 2010) and may be related to impaired selective attention and working memory in major depression (Borkowska and Rybakowski, 2001;Phillips et al., 2003;Desseilles et al., 2009).”
  • The study demonstrated aberrant connectivity of visual cortical areas with regions involved in visual processing, including the lingual gyrus, fusiform gyrus, inferior occipital gyrus and calcarine gyrus.

    “Aberrant connectivity of the visual cortical areas with regions known to be involved in visual processing, such as the lingual gyrus, fusiform gyrus, inferior occipital gyrus and calcarine gyrus, has been demonstrated in this study (Beckmann et al., 2005;Damoiseaux et al., 2006;Veer et al., 2010).”

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.
