As part of its activities, Paris Brain Institute provides a transparency portal for people who have participated in or participated in the research listed on this page. You may, on this portal, be informed about the use of personal data and biological samples collected in the course of studies in which you have participated or are participating, be informed about the results of studies we are conducting and in which we are participating and you may, if you wish, oppose the re-use of your personal data and/or biological samples for further research purposes.
Presentation
The existence of health databases or collections of biological samples now opens up new possibilities and the possibility of enhancing the quality of research results. National or international collaboration between teams of physicians and researchers is essential for scientific research. It allows for the exchange of ideas and saves time and efficiency. The results thus shared are more representative, therefore more robust and lead to faster progress in the acquisition of knowledge for the benefit of the health of all. This is particularly true for rare diseases that require a sufficient number of patients.
For this reason, it is necessary to encourage the reuse of data and biological samples already collected in the framework of research projects or databases set up for this purpose, in order to carry out projects of scientific interest and with the necessary supervision and information of the persons concerned.
Some research can be conducted by our research teams. There are other situations in which other researchers have specific expertise or in which we wish to participate in a collective effort to advance health knowledge. We can then carry out research in partnership with other researchers or transfer the data and biological samples needed for their own projects, while respecting the confidentiality of these data.
Each new research project conducted at Paris Brain Institute or by another organization will be conducted in accordance with the commitment made by the responsible organization to comply with a reference methodology developed by the CNIL to guide the research. Failing this, it will be the subject of an application for authorisation from the Commission.
Whatever the research project and in order to preserve their confidentiality, your data and/or biological samples will be entrusted to our public or private partners without your identity, but with a confidential code of which only the investigator centre holds the key of correspondence. Furthermore, only information strictly necessary to answer the scientific questions raised will be transmitted.
In the event of data transmission, we first draw up a contract in order to guarantee security, respect for the conditions of use of the data and respect for your rights. If the partner is located outside the European Union, the transfer of your coded personal data will be subject to appropriate and adapted safeguards to guarantee the security of your data.
You will be informed of the re-use of biological data and/or samples on this site, which will be updated with each research project. This page will detail all the information relating to the processing of your data within the framework of these new projects, in particular, for each project concerned, the identity of the controller and the purposes pursued justifying the re-use of your data which will necessarily be related to the initial study in which you participated. This will help you understand the context and issues of the research conducted on this data.
With this information, you can choose to exercise your rights in each subsequent search. The posting of projects on the website is considered as information for this re-use of data and therefore there are no plans to send you an individual letter of further information for each research project.
If you do not agree to the use of your data or biological samples for future research, please write to opposition.recherche@icm-institute.org. As soon as your request for objection is taken into account, we guarantee that your data and/or biological samples will never be made available and will therefore never be used for other scientific research projects.
You may also object to the re-use of your data and/or biological samples for a given scientific research project(s) by contacting the contact point mentioned in the description of each project. Your data and/or biological samples will not be used for the project(s) concerned but may be used for those for which you have not expressed opposition.
When your data is used, you can assert your rights:
- You can access your data and in case of error you can ask to correct your data. If it is medical information, it is best to go through your health care professional who alone can judge the accuracy of the information.
- You may ask to limit the use of your data, which temporarily prevents its use for projects, for example, while it is being rectified.
- You can have these data erased. However, you should be aware that useful data collected prior to the exercise of your right to erasure, your right to object or the withdrawal of your research consent may continue to be treated as confidential if their erasure would compromise the achievement of the research objectives.
These rights apply to the body responsible for processing such data at the contact address provided on each information sheet of the research project or database concerned. Your identity will be verified to protect you from spoofing.
In case of difficulty in exercising your rights, you can contact Paris Brain Institute Data Protection Officer by e-mail (dpo@icm-institute.org) or by post (DPO, Institut du Cerveau - Paris Brain Institute - Hôpital de la Pitié-Salpêtrière - 47, boulevard de l’Hôpital - 75013 Paris).
You also have the right to lodge a complaint with the Commission nationale de l’informatique et des libertés (cnil.fr).

Studies UCS
Clinical-genetic study of the pathologies of the basal ganglia
Promoter or Head of the initial research: Inserm, 101 rue de Tolbiac, 75013 Paris
The project brings together a national network of clinicians specializing in the ailments of the basal ganglia. Its objective is to advance our knowledge of the molecular basis of these diseases by collecting large-scale clinical and genetic data in a standardized manner.
The populations studied in this research are patients with anomalous movements due to UCS (i.e. Parkinson's Disease, Huntington's Disease, Essential Trembling…) as well as related relatives and healthy subjects.
The aim of the project is to identify the genetic susceptibility factors involved in the pathologies of the basal ganglia, those that modify their expression, identify biomarkers and determine the natural evolution of these diseases and their different manifestations.

Iceberg Study (Pr. Marie Vidailhet)
Investigation of factors predictive of onset and progression of Parkinson’s disease
Initial Study Sponsor/Processor: Inserm
Study population: the populations studied in this research are patients with Parkinson’s disease (PD), REM sleep disorders, and related relatives and healthy subjects.
Project objectives: the strategy is to identify early the evolutionary factors of the disease and to consider therapeutic measures to change its course or to identify risk groups requiring a personalized approach.
Thus, our approach aims to:
- Identify markers prior to the onset of motor signs
- Identify PD progression markers
- Isolate prognostic factors
The identification of sub-populations at risk of rapid evolution or with particular evolutionary profiles could lead to the development of targeted therapeutics.
This research is therefore intended to identify and validate markers for predicting and monitoring the progression of dopaminergic and non-dopaminergic PD lesions from the prodromal and clinical expression phases.
To this end, the following national and international collaborations have been established:

Collaboration with Nadya Pyatigorskaya https://n.neurology.org/content/96/3/e460.abstract
Nature of project: data sharing (longitudinal clinical and paraclinical)
Pathology: Parkinson's disease
The classical model of Braak’s neuropathological staging in Parkinson’s disease suggests that brain lesions progress from medullary oblongata to cortex. An alternative model in which neurodegeneration occurs first in the cortex has also been proposed. These two models may correspond to different patient phenotypes. To test these two models and determine if they were influenced by the presence of REM sleep behaviour disorders (RRDs), we used multimodal MRI and partial least squares trajectory modeling (PLS-PM) assuming that patients with RRDs had a distinct neurodegeneration pattern.

- DIGIPD : Validating DIGItal biomarkers for better personalized treatment of Parkinson's Disease
International collaboration with different research teams
(France, Allemagne, Luxembourg, Belgique) https://www.digipd.eu/en/objectives.html
Nature of the project: sharing of data (longitudinal clinical and paraclinical)
Pathology: Parkinson's disease
Objective: DIGIPD evaluates modern digital technology for impaired walking, voice, and facial movements. In evaluating these digital biomarkers, DIGIPD unravels the relationship between numerical measurements, established clinical questionnaires and molecular biomarkers by testing whether they can distinguish between patients with PD and control patients and whether they are relevant for predicting disease progression using artificial intelligence. In addition, it will allow pharmaceutical companies to use data from a group of patients with similar disease progression to increase the chances of clinical trials of new personalized drugs.
