Abstract

BackgroundThe remarkable advances achieved in Parkinson's disease (PD) research across clinical science, genetics, molecular and cellular mechanisms, disease modeling, pathophysiology, biomarkers, and therapeutics reflect not only scientific innovation but also the evolution of collaborative research. The field has transitioned from single-investigator observations and isolated institutional efforts to regional networks and global consortia that now drive many of the most important PD discoveries.ObjectiveTo review the evolution of collaborative research approaches in PD, examine barriers and challenges to global research synergy, and discuss potential solutions to promote equitable and impactful international collaboration.State of the Art and Future DirectionsKey challenges to global PD research include funding inequities, regulatory and data-sharing complexities, difficulties in standardization and generalizability, language barriers, limited interdisciplinary communication, unequal resource allocation, insufficient training opportunities, regional mistrust, and the need to address diverse cultural contexts. Successful international initiatives have demonstrated the value of shared databases, harmonized protocols, cross-border funding mechanisms, and synergistic multidisciplinary, multicultural, and multinational partnerships. Future efforts should be grounded in trust, transparency, ethical reciprocity, equitable governance, and meaningful stakeholder engagement, while prioritizing capacity building, workforce development, and sustainable training opportunities.ConclusionsAccelerating progress in PD research requires collaborative frameworks that integrate diverse populations, disciplines, institutions, and regions. Strengthening research infrastructure, community engagement, culturally grounded education, participant-centered research practices, and scientific leadership, particularly in low- and middle-income countries, will be essential to ensure that all populations can contribute to and benefit from scientific advances, fostering a more equitable and effective global PD research ecosystem.
