Objective To estimate brain grey matter volume changes and location of abnormal brain regions cerebrum in early stage of bipolar disorder I (BD),in order to provided objective basis for diagnosing early stages BD.Methods 1 7 cases of BD with duration less than 2 years and 1 7 normal controls were recruited in this study.The volumetric difference of grey matter between two groups were analyzed by using voxel-based morphometry(VBM)software.Statistical threshold was voxel> 100,P <0.001 (uncor-rected).Results Compared to the normal controls,the grey matter volume of BD patients decreased in the left dorcial anterior cingu-late cortex(ACC),left insular,right sub-genu ACC,left superior temporal cortex,bilateral hippocampus-parahippocampus-amydala and left posterior lobe of cerebellum(P <0.001).Conclusion The grey matter volume of early stage BD patients is decreased,main-ly locating in the bilateral limbic system,the superior temporal gyrus and the cerebellar cortex,which probably is the morphological appearance of pathomechanism in early stages of BD.
