Rapid Eye Movement Sleep Behavior Disorder

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.

Rapid eye movement (REM) sleep behaviour disorder (RBD) is a parasomnia that is characterized by abnormal behaviours occurring during REM sleep（a sleep stage）, often as dream enactments that can cause injury. Treatment options are limited. Pharmacological treatments include melatonin and clonazepam, but they have varying degrees of adverse reactions. Acupuncture is a green and safe means of treatment and has therapeutic value in sleep disorders. Using the theory of traditional Chinese medicine, the acupuncture treatment of RBD group points was formulated, and good clinical effect was obtained in the early clinical practice.This study was designed to explore the clinical efficacy of acupuncture in the treatment of RBD. Thirty patients with RBD who met the inclusion and exclusion criteria were randomly divided into acupuncture group and sham acupuncture group, and were subjected to a 2-week screening period, a 4-week treatment period, and a 2-week follow-up period.The investigators will primarily observe whether there is a reduction in the number of weekly RBD events recorded by the wCIRUS-RBD questionnaire before and after treatment, and the reduction in the RWA index recorded by video polysomnography (vPSG).
