Abstract

Background Previous structural imaging studies found evidence of brain morphometric changes in major depression (MD) patients, but they rarely excluded compounding effects of some important factors, such as medication and brain degeneration. This study sought to explore the brain morphometric changes of first-episode, drug-naïve, non-late-life adult MD patients with optimized voxel-based morphometry (VBM) method.Methods Twenty-three first-episode, drug-naïve, non-late-life adult depressed patients and 23 healthy control subjects were enrolled in this study. Subjects underwent high-resolution magnetic resonance imaging, and optimized VBM was performed to analyze the morphometric data. A partial correlation model was used to analyze associations of morphometric changes with Hamilton Depression Rating Scale scores and illness duration.Results Depressed patients showed significant gray matter volume reduction in the bilateral limbic system, especially in hippocampus. These changes did not significantly correlate with symptom severity or illness duration.Conclusions Our findings provided new evidence of gray matter deficits in first-episode, drug-naïve, non-late-life adult MD patients. It supported that the reduction of hippocampal volume is a trait for MD patients and further highlighted the important role of the limbic system, particularly hippocampus in the pathophysiology of MD.

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.
