The primary objectives of this study are to explore the effects and mechanisms of probiotic intervention on improving REM sleep behavior disorder (RBD) in patients with Parkinson's disease (PD) from both clinical and animal experimental levels. The study aims to elucidate the scientific hypothesis that "probiotic intervention improves RBD in PD patients through a neuroendocrine mechanism," providing a theoretical basis for the mechanism by which probiotic intervention alleviates RBD symptoms in PD patients.
Research Content:
Establishing imaging detection technical processes and parameters for RBD.Collecting pre- and post-probiotic treatment imaging parameters and comparing them with RBD improvement to explore the mechanism by which probiotics improve PD patient RBD.Detecting fecal microbiota abundance and blood and fecal metabolite concentrations to discuss the biochemical mechanism by which probiotics improve PD motor symptoms and RBD.
Research Methods:
Patient Recruitment:
Enrolling PD-RBD, iRBD, and healthy control subjects, with specific inclusion and exclusion criteria based on clinical diagnosis and symptomatology.
Clinical Assessments and Tests:
Utilizing standardized scales such as RBDSQ, RBD-HK, UPDRS-III, and Hoehn-Yahr staging for symptom evaluation. Conducting polysomnography (PSG) for RBD diagnosis and exclusion of other sleep disorders.
Multimodal Imaging Data Collection:
Employing 3.0T MRI for high-precision anatomical imaging, resting-state functional MRI (rs-fMRI), and proton magnetic resonance spectroscopy (1H-MRS) for glutamate, GABA, and other metabolites in specific brain regions.
Performing 123I-MIBG cardiac scintigraphy to assess cardiac sympathetic nerve function.
Laboratory Tests:
Measuring concentrations of glutamate, GABA, acetylcholine, and other metabolites in blood and fecal samples. Assessing fecal microbiota abundance through 16S rRNA gene sequencing.
