Abstract:
Objective:To investigate the alteration of glymphatic system based on diffusion tensor image-analysis along the perivascular space(DTI-ALPS)in bipolar disorder Ⅰ(BD-Ⅰ).Methods:A total of 44 BD-Ⅰ patients(BD-Ⅰ group) admitted to the Affiliated Brain Hospital of Guangzhou Medical University from January 2012 to December 2017 were selected.In addition, totally 30 healthy controls (HC group) were recruited. The diffusion tensor image data were analyzed retrospectively, and along the perivascular space (ALPS) index was calculated. Hamilton anxiety scale (HAMA), 17-item Hamilton depression rating scale (HAMD-17), Young mania rating scale (YMRS) and global assessment function (GAF) were used to evaluate the severity of anxiety, depression, mania and social function respectively. SPSS 25.0 software was used for t-test, Z-test and chi-square test, and the differences in clinical data and DTI-ALPS index between the two groups were compared. The partial correlation test was used to analyze the correlations between DTI-ALPS index and the clinical indicators such as HAMA, HAMD-17, YMRS and GAF. Results:The DTI-ALPS indexes in left(1.69±0.17), right(1.44±0.15) and bilateral cerebral hemispheres(1.56±0.15) of BD-Ⅰ group were lower than those in HC group ((1.71±0.15), (1.46±0.13) and (1.58±0.12)), but the differences were not statistically significant ( t=-0.441, -0.545, -0.556, all P>0.05). After controlling for gender, age, years of education and course of disease, there were significant negative correlations between bilateral average DTI-ALPS index and somatic anxiety ( r=-0.334, P=0.038), as well as between right DTI-ALPS index and somatic anxiety( r=-0.349, P=0.030) in BD-Ⅰ group. Conclusion:The dysfunction of cerebral glymphatic system is not obvious in BD-Ⅰ patients, but their anxiety may be related to dysfunction cerebral glymphatic system.
