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.
See worldwide coverage and update dates ↓Studies with early results appear under “Results reported” even if recruitment continues.
Registry records retrieved 2026-10-13 (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 use sites with matching or unreported status. A country recorded by WHO does not confirm an open local site.

WORLDWIDE COVERAGE
Studies are imported from ClinicalTrials.gov, WHO’s international collection and the European CTIS registry. WHO brings together national and regional registries, including records from Asia, Africa and Latin America. Recruiting and upcoming listings have English introductions; older records awaiting an introduction show their registry title.
We aim for broad worldwide coverage, but no registry includes every study. Unregistered studies, reporting delays and missing translations can leave gaps. A missing paper does not mean that no results exist.
