- Brief Summary
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 mechan...
- Detailed Description
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 thro...
