Summary

Parkinson's disease(PD) may cause the autonomic nervous system's improper functioning, which is responsible for regulating the intestinal tract movement. A certain degree of degeneration of digestive system function can cause PD patients to constipation symptoms. Studies have shown that up to 63 percent of people with Parkinson's disease experience constipation. What is more, medications for PD, including levodopa and dopamine agonist, can also cause constipation. In recent years, an increasing number of studies have been conducted to investigate gut microflora and their influence on the central nervous system. Furthermore, some studies of Parkinson's disease have confirmed that gut microflora plays a vital role in the occurrence and development of Parkinson's disease.

The purpose of this study is to evaluate the efficacy and safety of fecal microbiota transplantation in the treatment of constipation symptoms in patients with Parkinson's disease receiving a steady dose of levodopa. We will also analyze intestinal flora diversity in patients with Parkinson's disease with constipation. The investigation of the gut microbiome may emerge as a new therapeutic measure to treat constipation associate with Parkinson's disease.
