The functional neuroanatomy of bipolar disorder

Abstract

In this manuscript, research articles using functional magnetic resonance imaging (fMRI) to study adult patients with bipolar disorder were reviewed. The findings from these studies identify altered brain activation in five regions in cortico-limbic pathways responsible for emotional regulation: portions of the prefrontal cortex; anterior cingulate cortex; amygdala; thalamus; and striatum. The most consistent findings were overactivation of amygdala, striatum, and thalamus. Findings in prefrontal cortex were less consistent, but most studies also showed increased activation in ventrolateral and dorsolateral prefrontal cortical areas. Excessive activation in brain regions associated with emotional regulation may contribute to the affective symptoms of bipolar disorder. However, there are several important limitations in this body of research. Even when similar tasks were used, brain activation was often discrepant among studies. Most fMRI studies examined small samples (ten or fewer bipolar subjects) limiting statistical power. Additionally, most studies were confounded by patients taking psychotropic medications. Nonetheless, from this work an anterior limbic over-activation model of bipolar disorder is emerging.

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.
