About this trial
The Parkinson's Disease Case-Control Study is a study of healthy volunteers and patients with Parkinson's disease aged 50-75 years living in Hangzhou, China. This study aims to systematically investigate the differences in intestinal fungi between patients and healthy volunteers, find the key strains, and explore the molecular mechanism of Parkinson's disease with multi-omics data. Another aim of this study is to explore the association between intestinal fungi and brain structure and function from the perspective of the gut-brain axis by combining brain image data.
