Major depressive disorder (MDD) is one of the most common psychiatric disorders, and present various symptoms such as the dysregulation of mood, cognition, and behavior. The purpose of the present study was to investigate the morphometric change in MDD patients by voxel-based morphometry (VBM) and sulcal depth analyses. Forty-six MDD patients (mean age, SD; 36.07±14.34), and 23 age- and sex-matched normal controls (NML) (mean age, SD; 36.78±14.42) were included. Coronal 3D T1 magnetic resonance imaging (MRI) was obtained with the resolution of isotropic 1.0 mm. To check morphological changes of brain, T1 MRIs were objectively processed by VBM and sulcal depth methods. In sulcal depth analysis, depressed patients showed reduced sulcal depth in the areas of left posterior ramus of the lateral sulcus, superior frontal sulcus, supramarginal gyrus, central sulcus (Rolando's fissure), and Heschl's gyrus. And right posterior ramus of the lateral sulcus, temporal plane of the superior temporal gyrus, anterior transverse collateral sulcus, and central sulcus (Rolando’s fissure) were also reduced compared to NML. But, VBM analyses did not showed significant finding. Reduced sulcal depth in the motor and emotion related areas were found in patients with MDD. Especially reduced sulcal depth in bilateral central sulci which are connecting between primary motor cortex and primary sensory cortex seems to be related with social and physical anhedonia in MDD.
