Fecal Microbiota Transplantation in Parkinson's Disease.

Starting soon · Not applicable

Conditions studied: Parkinson's Disease

In brief

Fecal microbiota transplantation (FMT) is an effective and safe treatment for Clostridioides difficile infection (CDI). Though CDI is the only indication for FMT, more and more preliminary data on FMT in neurological disorders are reported due to gut-brain axis. This study is a pilot study to apply FMT on patients with Parkinson's disease (PD). The effect of FMT on motor and non-motor symptoms in PD will be also evaluated.
