Primary | Study microbiome composition to explain the exact nature of the dysbiosis (microbial imbalance) | The investigators anticipate confirming their prior findings that patients with PD have dysbiosis, and further identifying the nature of the dysbiosis including changes at the species and strain level. | 4 years | |
Secondary | Identify the potential contributing factors for dysbiosis in PD | It is well established that environmental factors such as diet, as well as genetics, impact microbiome composition.Currently, there are no data for how environment impacts the microbiome in PD. | 4 years | |
Secondary | Determine how dysbiosis promotes PD | The investigators will determine SCFA (Short chain fatty acids) concentrations in serum and stool from early onset PD patients and healthy controls. The investigators will correlate serum, stool data, PD symptoms and disease severity obtained through validated PD questionnaires. | 4 years |
