Abstract

BACKGROUND: To identify changes in brain activation patterns in bipolar disorder (BD) and unipolar depression (UD) patients. METHODOLOGY/PRINCIPAL FINDINGS: Resting-state fMRI scans of 16 healthy controls, 17 BD and 16 UD patients were obtained. T-test of normalized regional homogeneity (ReHo) was performed in a voxel-by-voxel manner. A combined threshold of á = 0.05, minimum cluster volume of V = 10503 mm(3) (389 voxels) were used to determine ReHo differences between groups. In UD group, fMRI revealed ReHo increases in the left middle occipital lobe, right inferior parietal lobule, right precuneus and left convolution; and ReHo decreases in the left parahippocampalgyrus, right precentralgyrus, left postcentralgyrus, left precentralgyrus and left cingulated. In BD group, ReHo increases in the right insular cortex, left middle frontal gyrus, left precuneus, left occipital lobe, left parietal, left superior frontal gyrus and left thalamus; and ReHo decreases in the right anterior lobe of cerebellum, pons, right precentralgyrus, left postcentralgyrus, left inferior frontal gyrus, and right cingulate. There were some overlaps in ReHo profiles between UD and BD groups, but a marked difference was seen in the thalamus of BD. CONCLUSIONS/SIGNIFICANCE: The resting-state fMRI and ReHo mapping are a promising tool to assist the detection of functional deficits and distinguish clinical and pathophysiological signs of BD and UD.

  • Cerebellar abnormalities (reduced volumes, abnormal functional connectivity, abnormal metabolism) are present in bipolar disorder compared to neuronormative populations.

    “In bipolar disorder, subjects show reduced cerebellar volumes (Baldacara et al., 2011; DelBello et al., 1999; Mills et al., 2005), abnormal cerebellar functional connectivity (Liang et al., 2013), and abnormal cerebellar metabolism (Johnson et al., 2018; Magnotta et al., 2022) compared to neuronormative populations.”

    From A double-blind, randomized, sham-controlled clinical trial of cerebellar intermittent theta burst stimulation for bipolar disorder: Safety, tolerability, mood and cognitive effects (2025) · cites this paper as Liang et al., 2013

    Table 3 (Results, §2) reports decreased regional homogeneity (ReHo) in the right anterior cerebellum of bipolar-disorder patients compared with controls. The Introduction describes ReHo as local synchronization of fMRI signals, but the Discussion distinguishes this method from functional-connectivity analysis. The paper therefore supports a cerebellar functional abnormality, not a direct finding of abnormal cerebellar functional connectivity. (LLM, conf=0.84)

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.
