The OPDC Discovery cohort is a prospective, longitudinal study that has recruited patients with early idiopathic Parkinson Disease, healthy controls and participants at risk of PD. The study also includes participants with REM Sleep Behaviour Disorder. Over 1500 subjects have been recruited to the cohort, including 1087 people with Parkinson’s, 300 healthy controls, 111 First degree PD relatives and 151 PSG-diagnosed REM sleep behaviour disorder, thought to be ‘at-risk’ of developing future Parkinson’s. All patients have a clinical assessment repeated every eighteen months so we can better understand the progression of Parkinson’s over time. Over 500 patients have been seen for a second visit which has allowed us to identify some important differences in the way Parkinson’s progresses in different people.
