Brief summary (registry, in English)
Background Our understanding of PD has stagnated, partly due to the limited patient diversity and brief followup captured in most study cohorts. Additionally, potentially valuable biomarkers derived from different types of measurements are rarely analyzed in an integrated fashion. Objective This study aims to create a longitudinal dataset of clinical, molecular, imaging, and continuous wearable sensor-based data from a representative Parkinson's disease (PD) cohort. Data will be made available to researchers worldwide to accelerate the discovery of novel etiological insights, development of new therapeutic approaches, and personalized disease management. For this purpose, an extensible norm for sharing research data will be developed, meeting the latest data privacy and security standards. Methods Supported by a multinational, public-private partnership, a prospective cohort study was designed to include 650 representative PD patients (disease duration \<5 years). Comprehensive follow-up for at least 2 years includes: (1) annual assessment at the study center for acquisition of detailed clinimetric data, magnetic resonance imaging, and biospecimens (plasma, serum, cerebrospinal fluid (CSF), stool) and (2) collection of data from the home environment, using self-assessments and an advanced wrist-worn wearable device to continuously measure biological and environmental signals. Collection, storage, and sharing of these research data will be facilitated by a new method to protect privacy and enhance security using polymorphic encryption and pseudonymization (PEP), a methodology that combines advanced encryption with distributed pseudonymization and data access management. Conclusion This study is unique, as it includes a cohort of unbiased subjects with recently diagnosed PD, creating an unprecedented dataset that combines longitudinally collected clinical, molecular, imaging, and data from wearable sensors using state of the art technology. The single-center study design minimizes measurement variability. Finally, the innovative methodology for data privacy and protection might serve as a new international standard for sharing research data.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Contraindicated for MRI, e.g. claustrophobia, presence of an active implant, pacemaker, insulin pump, neurostimulator, ossicle prosthesis, and/or other medical device or other non-removable metal part incompatible with MRI.
- For lumbar puncture:
- Allergy to local anesthetic agents
- Medical history of compression of spinal cord, current local skin infection at the site of the lumbar puncture, developmental abnormalities in lower spine, blood coagulopathy, anticoagulant medication (Acenocoumarol, Warfarin, Dabigatran).
- Clinical (or previous MRI) evidence of structural cerebral abnormalities that are not compatible with the performance of a lumbar puncture such as malignancies, abscess, or obstructive hydrocephalus.
Other illness
- Subject is allergic to nickel.
Other
- Subject is pregnant or breastfeeding.
- Subject has co-morbidities that would hamper interpretation of parkinsonian disability, such as coincident musculoskeletal abnormalities, in the opinion of the Investigator.
Who the study is looking for
- Subject has Parkinson's disease of ≤5 years duration, defined as time since diagnosis made by a neurologist.
- Subject is an adult, at least 18 years of age.
- Subject can read and understand Dutch.
- Subject has completed the Informed Consent form, as approved by the Ethics Committee.
- Subject is willing, competent, and able to comply with all aspects of the protocol, including follow-up schedule and biospecimen collection.
