Abstract:

Objective  To investigate the abnormalities of gray matter volume in obsessive-compulsive disorder(OCD) patients relative to controls using the method  of voxel-based morphometry(VBM), and to analyze the extent of change relative to clinical symptom.    Methods  Using VBM to compare the MRI images of 31 adult OCD patients with 31 healthy controls. Correlation analyses were conducted between the structural abnormalities of gray matter volume in each brain area among patients relative to their clinical scores.    Results  Compared with the healthy controls, the OCD patients showed reductions of gray matter volume in left putamen, insula, premotor area, superior parietal and right angular gyrus (P<0.01,Alphasim corrected). The gray matter volumes of left putamen and insular in the OCD patients showed a negative correlation with the Beck anxiety inventory(BAI) scores.    Conclusion  The changes in gray matter volumes of left putamen, insula, premotor area, superior parietal lobule and right angular gyrus may be related to the pathogenesis of OCD. The declines of left putamen and insula are related to the abnormal anxiety in the OCD patients.
