What this trial studies

This observational study aims to explore the clinical characteristics and progression of Parkinson's disease (PD) in a longitudinal cohort of patients in China. It focuses on identifying biomarkers that can predict disease evolution and prognosis, addressing the heterogeneity of PD symptoms and progression rates. Data will be collected at baseline and during routine follow-up visits, including detailed patient histories and environmental factors. The study seeks to enhance understanding of PD's clinical features and potential genetic and environmental influences.
