[Abstract] Objective To explore the abnormal patterns of brain functional networks in type 2 diabetes comorbid depression (T2DD) by using Degree Centrality (DC) method of resting state functional magnetic resonance imaging. To further elucidate the neuroimaging mechanisms of T2DD.Materials and Methods Fifty-six T2DD patients, 59 type 2 diabetes mellitus (T2DM) patients without depression and 57 healthy volunteers were prospectively enrolled. The whole brain DC values of the three groups were compared, and the correlation analysis between the DC values of the brain regions with significant differences and clinical variables and cognitive psychological scale was extracted.Results Compared with control group and T2DM without depression group, T2DD group had lower cognitive score, depression score and anxiety score. Compared with the control group, the DC value of the right posterior cingulate gyrus decreased in T2DM without depression group, and the DC value of the right transverse temporal gyrus increased in T2DD group (GRF correction, voxel P<0.001, cluster P<0.05), no correlation was found between the DC values of these brain regions and the clinical data and the cognitive psychosocial scale scoring.Conclusions T2DD patients are associated with more severe emotional abnormalities and cognitive impairment. In resting state, abnormal topology of the functional network of the right transverse temporal gyrus may be a potential neuroimaging biological marker of T2DD brain damage.
