About

The aim of NS-PARK cohort are to describe the natural history of Parkinson's disease (PD), and to propose patients stratification models based on PD pathophysiological mechanisms. Patients are included at all PD expert centers in France. Standardized demographic, diagnosis, motor and non-motor symptoms evaluation, and treatment information are collected, and clinical data are updated at each visit of the patient at the center. A blood sampling is perform at baseline for genetic testing and implement an associated biocollection.

Full description

The national clinical research network for Parkinson's disease (NS-PARK/FCRIN) reassembles all expert centers in Parkinson's disease (PD) in France. Its aim is to promote clinical research in Parkinson's disease and movement disorder, to better understand the pathophysiology of PD, foster the development of new therapeutic strategies, and move towards personalized medicine. To help centers for prescreening, a national registry of PD patients followed in each centers has been implemented in 2016 to collect minimal relevant clinical information of patients followed in each center including demographic data, age at diagnosis, standardized motor and non-motor symptoms evaluation, and treatment. Data are updated at each visit of the patient in the center. De facto, this registry became a longitudinal cohort of PD patients followed in NS-PARK centers. In 2020, NS-PARK received funding to associate a biocollection to this clinical cohort.

The aim of NS-PARK cohort are to describe the natural history of PD progression in clinical routine in France, to develop new models of PD describing the different progression profiles, and to propose patients stratification based on PD pathophysiological mechanisms. The cohort will also serve as a platform to discover new PD genes and genetic modifiers of disease progression or response to treatment.
