Abstract

Objective Anxious depression is a distinct clinical subtype of major depressive disorder (MDD) characterized by palpitations, somatic complaints, altered interoceptive awareness, high risk of suicide, and poor response to pharmacotherapy. However, the neural mechanisms of anxious depression are still not well understood. In this study we investigated changes in neural oscillation during the resting-state of patients with anxious depression by measuring differences in the amplitude of low-frequency fluctuation (ALFF).Methods Resting-state functional magnetic resonance imaging was acquired in 31 patients with anxious depression, 18 patients with remitted depression, as well as 68 gender- and age-matched healthy participants. We compared the differences both in the ALFF and fractional ALFF (fALFF) among the three groups. We also examined the correlation between the ALFF/fALFF and the severity of anxiety as well as depression.Results Anxious depression patients showed increased ALFF/fALFF in the right dorsal anterior insular cortex and decreased ALFF/fALFF in the bilateral lingual gyrus relative to remitted depression patients and healthy controls. The increased ALFF in the dorsal anterior insula was also positively correlated with stronger anxiety in the anxious depression group. Anxious depression patients also displayed increased fALFF in the right ventral anterior cingulate cortex (ACC) compared to remitted depression patients and healthy controls.Conclusions Our results suggest that alterations of the cortico-limbic networks, including the right dorsal anterior insula and right ventral ACC, may play a critical role in the physiopathology of anxious depression.

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.
