Abstract

Generalized anxiety disorder (GAD) and panic disorder (PD) are most common anxiety disorders with high lifetime prevalence while the pathophysiology and disease‐specific alterations still remain largely unclear. Few studies have taken a whole‐brain perspective in the functional connectivity (FC) analysis of these two disorders in resting state. It limits the ability to identify regionally and psychopathologically specific network abnormalities with their subsequent use as diagnostic marker and novel treatment strategy. The whole brain FC using a novel FC metric was compared, that is, scaled correlation, which they demonstrated to be a reliable FC statistics, but have higher statistical power in two‐sample t ‐test of whole brain FC analysis. About 21 GAD and 18 PD patients were compared with 22 matched control subjects during resting‐state, respectively. It was found that GAD patients demonstrated increased FC between hippocampus/parahippocampus and fusiform gyrus among the most significantly changed FC, while PD was mainly associated with greater FC between somatosensory cortex and thalamus. Besides such regional specificity, it was observed that psychopathological specificity in that the disrupted FC pattern in PD and GAD correlated with their respective symptom severity. The findings suggested that the increased FC between hippocampus/parahippocampus and fusiform gyrus in GAD were mainly associated with a fear generalization related neural circuit, while the greater FC between somatosensory cortex and thalamus in PD were more likely linked to interoceptive processing. Due to the observed regional and psychopathological specificity, their findings bear important clinical implications for the potential treatment strategy.

  • Hippocampus function, structure, and functional connectivity with other regions is compromised in individuals with PTSD, GAD, and PD.

    “The hippocampus is another brain structure within the medial temporal lobe whose function, structure, and functional connectivity with other regions is comprised in individuals with PTSD, GAD, and PD (Cui et al, 2016;Fani et al, 2012b;Woon et al, 2010).”

    The FC Alterations in GAD and PD section reports altered hippocampus/parahippocampus connectivity in GAD. The Introduction also reports prior findings of reduced hippocampal volume in GAD and increased hippocampal activation during agoraphobia-specific stimuli in PD. The paper does not establish hippocampal structural or connectivity changes in PD, and it does not address PTSD; page numbers are unavailable in our copy. (LLM, conf=0.87)

  • Regions of the medial prefrontal cortex (mPFC), including the rostral anterior cingulate cortex, subgenual ACC, and medial frontal gyrus, are heavily connected to the amygdala and hippocampus, and critically involved in emotion regulation, attention bias, and fear extinction in individuals with PTSD and other anxiety disorders.

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.
