Parkinson's Institute and Clinical Center
Introduction
The Parkinson's Institute and Clinical Center (commonly known as The Parkinson's Institute or PI) is a nonprofit research institute and clinical center dedicated exclusively to Parkinson's disease research and patient care. Founded in 2002 in Sunnyvale, California, it represents one of the few institutions in the world focused solely on Parkinson's disease, combining basic science research with comprehensive clinical care under one roof[@parkinsons].
The institute was established to bridge the critical gap between laboratory science and patient care, recognizing that Parkinson's disease research benefits from close integration of clinical observation and basic investigation. This approach has enabled the institute to make significant contributions to understanding disease mechanisms, identifying biomarkers, and developing novel therapeutic approaches[@pifi-research].
In 2019, the Parkinson's Institute merged with the Parkinson's Foundation, creating the largest organization in the world dedicated to Parkinson's disease research, care, and advocacy. This merger enhanced the institute's capacity for large-scale clinical research and expanded access to experimental therapies through the Parkinson's Foundation's network of centers.
Historical Background
Foundation and Early Years
The Parkinson's Institute was founded in 2002 by the Parkinson's Disease Foundation (now the Parkinson's Foundation), with support from the Michael J. Fox Foundation and other donors. The founding vision was to create a dedicated center that would accelerate progress toward better treatments and ultimately a cure for Parkinson's disease.
The institute was initially housed in facilities in Sunnyvale, California, adjacent to the El Camino Hospital. This location provided access to clinical facilities while maintaining proximity to the vibrant biotechnology and pharmaceutical industry in the San Francisco Bay Area.
Leadership and Development
The institute's first Scientific Director was Dr. J. William Langston, a renowned Parkinson's disease researcher whose work had established the parkinsonian syndrome caused by MPTP contamination. Dr. Langston's vision shaped the institute's research programs and established its focus on translational research.
Key milestones in the institute's history include:
- 2004: Launch of the Parkinson's Institute Brain Bank
- 2006: Establishment of the Clinical Trials Unit
- 2008: Opening of the Movement Disorders Clinic
- 2012: Start of the Parkinson's Progression Markers Initiative (PPMI) site
- 2015: Development of biomarker laboratory
- 2019: Merger with Parkinson's Foundation
Research Programs

The Parkinson's Institute maintains a robust clinical research program encompassing multiple aspects of Parkinson's disease. The Clinical Research Unit coordinates approximately 30 active studies at any given time, ranging from observational biomarker studies to Phase II therapeutic trials[@pifi-clinical].
Clinical Trials Program
The institute's clinical trials program has been central to its mission. As a leading enrollment site for Parkinson's disease clinical trials, the institute has participated in studies of:
