Abstract

Objective: To investigate neural activity in prefrontal cortex and amygdala during bipolar depression. Methods: Eleven bipolar I depressed and 17 normal subjects underwent functional magnetic resonance imaging (fMRI) while performing a task known to activate prefrontal cortex and amygdala. Whole brain activation patterns were determined using statistical parametric mapping (SPM) when subjects matched faces displaying neutral or negative affect (match condition) or matched a geometric form (control condition). Contrasts for each group for the match versus control conditions were used in a second‐level random effects analysis. Results: Random effects between‐group analysis revealed significant attenuation in right and left orbitofrontal cortex (BA47) and right dorsolateral prefrontal cortex (DLPFC) (BA9) in bipolar depressed subjects. Additionally, random effects analysis showed a significantly increased activation in left lateral orbitofrontal cortex (BA10) in the bipolar depressed versus control subjects. Within‐group contrasts demonstrated significant amygdala activation in the controls and no significant amygdala activation in the bipolar depressed subjects. The amygdala between‐group difference, however, was not significant. Conclusions: Bipolar depression is associated with attenuated bilateral orbitofrontal (BA47) activation, attenuated right DLPFC (BA9) activation and heightened left orbitofrontal (BA10) activation. BA47 attenuation has also been reported in mania and may thus represent a trait feature of the disorder. Increased left prefrontal (BA10) activation may be a state marker to bipolar depression. Our findings suggest dissociation between mood‐dependent and disease‐dependent functional brain abnormalities in bipolar disorder.

  • Because bipolar disorder pathophysiology is strongly associated with prefrontal cortex neurocircuitry, it is important to determine whether stimulating over this area has advantages compared with the vertex.

    “Because the pathophysiology of bipolar disorder is strongly associated with prefrontal cortex neurocircuitry, 28 it is important to determine if there are advantages to stimulating over this area compared with the vertex.”
  • Patients with mood disorders have substantial disruptions in interpersonal functioning.

    “On balance, patients with mood disorders experience substantial disruptions in interpersonal function, [30][31][32][33][34]”
  • Depressed patients with bipolar disorder have shown elevated amygdala activity and attenuated responses in the OFC and DLPFC to neutral and negative faces.

    “Depressed patients with bipolar disorder have also shown elevated activity in the amygdala 102 and attenuated responses in the OFC and DLPFC to neutral and negative (e.g., angry, fearful, sad) faces.”
  • On average, neural activity is most commonly decreased in the DLPFC and increased in the left amygdala, the fusiform gyrus and the inferior frontal gyrus in patients with mood disorders.

    “On average, neural activityis most commonly decreased in the DLPFC 30,59,68,76 and increased in the left amygdala, 55,74,76,79,98,99 the fusiform gyrus 82,93,98 and the inferior frontal gyrus 82,90,98 in patients with mood 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.
