Multimodal Image Technologies Investigate the Role and Mechanism of Probiotics in Improving RBD with Parkinson's Disease

Rapid eye movement sleep behavior disorder (RBD) is important non-movement feature, and also the important risk factor of Parkinson's disease (PD). In our previous work, we found that the movement features and RBD of PD patients improved after taking probiotics. The later was not reported before and the mechanism not clear. To investigate its role and mechanism, we plan to enroll patients of PD-RBD, idiopathic RBD, and healthy control, collect data of multimodal image technology before and after probiotic treatment，including resting state functional MRI，1H-MRS，123I-MIBG; analyze these data with clinical features, including UPDRS -III score, RBD-HK score , as well as the bacteria abundance and level of glutamate，GABA in blood and stool. Then, construct PD mouse model by fecal transplantation of PD patient, give or not give mouse probiotics treatment, and detect the level of glutamate, GABA, and so on, as well as α-synuclein of each brain area of each group, to explore the role and mechanism of probiotics in improving RBD and movement disorder of PD.
