Research Progress on the Effect and Mechanism of Probiotics in Relieving Parkinson's Disease Related Symptoms

Abstract

Parkinson's disease (PD) is a common neurological disorder of the brain. In recent years, there is increasing evidence that intestinal flora dysbiosis is closely related to the occurrence and development of PD. This suggests that intestinal microorganisms may be a new strategy for the treatment of PD. Probiotics are a group of active microorganisms that can colonize the host gut and play a beneficial role in the health of the body, and are of great significance to maintaining the intestinal microecological balance. Studies have shown that probiotics can effectively prevent and improve PD through the gut-brain axis, and the potential mechanisms of action include regulating intestinal microecology, alleviating inflammatory response and oxidative stress damage, and promoting the expression of neurotrophic factors. This article reviews the changes of intestinal flora in PD, the mechanisms of intestinal flora in the pathogenesis of PD, and the improvement effect and mechanisms of probiotics on PD-related symptoms, in order to provide a theoretical basis for probiotics to prevent and alleviate PD.
