Abstract

Rationale Abnormal amygdala and frontocortical responses to emotional stimuli are implicated in bipolar disorder (BD) and have been proposed as potential treatment targets.Objectives The aim of this study was to investigate amygdala and frontocortical responses to emotional face stimuli in BD and the influences of mood-stabilizing medications on these responses.Methods Functional magnetic resonance imaging was performed while 17 BD participants (5 unmedicated) and 17 healthy comparison (HC) participants viewed faces with happy, sad, fearful, or neutral expressions.Results The group by stimulus-condition interaction was significant (p<0.01) for amygdala activation, with the greatest effects in the happy face condition. Relative to HC, amygdala increases were greater in unmedicated BD, but lower in medicated BD. Rostral anterior cingulate (rAC) activation was decreased in unmedicated BD compared to HC; however, BD participants taking medication demonstrated rAC activation similar to HC participants.Conclusions Although the sample sizes were small, these preliminary results suggest that BD is associated with increased amygdala and decreased rAC response to emotional faces. The findings also provide preliminary evidence that mood-stabilizing medications may reverse abnormalities in BD in the response of an amygdala-frontal neural system to emotional stimuli.

  • In a sample of bipolar patients with mixed illness states, amygdala activity in response to happy faces was greater in unmedicated patients but lower in medicated patients compared with controls.

  • During passive viewing paradigms, patients with bipolar disorder and those with MDD demonstrate hypoactivity in the DLPFC and OFC and hyperactivity in the amygdala and anterior cingulate (subgenual and pregenual), although evidence is less consistent for subcortical regions such as the amygdala and paralimbic 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.
