TAKE PART IN RESEARCH
Research explained in everyday language. Explore what teams around the world are trying to learn, who can take part and how to get in touch.
Browse worldwide registries ↓Registry records retrieved 2026-10-11 (UTC). Individual records may have older updates. Recruitment and eligibility must be confirmed with the study team.
A location is a starting point. Ask the team whether that site is accepting people and whether you can take part from where you live.
Introductions are AI-written from the registry in everyday language and have not been independently checked by a clinician. Open any study for its full name, original description and participation rules.
Studies name Parkinson’s or a related condition. Some include other conditions or healthy volunteers. Country filters include sites with matching or unreported recruitment status and exclude known closed sites.
