Participant registry

The registry is a bank of participants that centralizes people with Parkinson's disease who wish to participate in research projects.

This first infrastructure is of decisive use in the operation of the 3 axes of the QPN. It ensures optimal recruitment for the faster acquisition of data that will be included in the various QPN databases.

The system for storing and centralizing these potential participants allows for their selection according to inclusion and exclusion criteria specific to each study.
