French national reference center for rare epilepsies (CRéER)
The Reference Center for Rare Epilepsies (CRéER) at Necker-Enfants malades hospital is a constituent site of the national network of centers dedicated to the care of patients with rare epilepsies. CREER is made up of a coordinating center (Hôpital de la Timone, AP-HM) and several constituent and competence sites in partnership with patient associations extending throughout the national territory (metropolitan France and DOM).
Our reference center has integrated the DéfiScience rare diseases healthcare network, which brings together resources and expertises in the field of brain development and intellectual disability rare diseases.
Our Necker site is a founding and board member of the EpiCARE european network dedicated to rare and complex epilepsies (European Reference Network for Rares and Complex Epilepsies).

CRéER’s objective is to improve knowledge of rare epilepsies, their diagnoses, their causes, their social and societal impacts and to offer the best overall care including specific therapies, whether by using drugs, surgery or dietetics. We offer a translational clinical-research vision for all our areas of work in order to get back to the patient and his family with the appropriate and optimal care.
Particular importance is given to monitoring the cognitive development of patients, and neuropsychiatric disorders, the majority of rare epilepsies can be accompanied by cognitive, behavioral or psychological difficulties.
The transition to adulthood is another major focus of our network, our centers including pediatric and adult experts have the mission of preparing and improving this transition.
In order to achieve these objectives, our reference center aims to promote:
- improving patient care by ensuring early diagnosis of the type of epilepsy or syndrome;
- the proposal of different treatment modalities (medication, surgery, ketogenic diet, vagus nerve stimulator);
- multidisciplinary follow-up of patients taking into account developmental problems, psychiatric disorders and behavior;
- improving local care;
- the transition from pediatrics to the adult sector;
- the promotion of therapeutic trials and research around its themes at the national and international level;
- training for doctors and paramedical professionals.

Professor Rima Nabbout heads the epilepsies program and develops healthcare of excellence and research in order to carry out these missions for patients with rare epilepsies, in different areas of activity:



- Therapeutic pathway of the child with rare epilepsies and his parents
- Therapeutic pathway for infants and adolescents and their families with Bourneville tuberous sclerosis
The national diagnostic and care protocols (PNDS) are good practice guidelines for rare diseases. The objective of a PNDS is to explain to concerned professionals the optimal diagnostic and therapeutic care and the care pathway of a patient suffering from a given rare disease.
As planned in the second national rare diseases plan 2011-2014, they are developed by the rare diseases reference and competence centers using a method proposed by the Haute Autorité de Santé (HAS).
The PNDS include a « summary for the attending physician » section
- Dravet syndrome (2021)
- Tuberous sclerosis complex (2021)
- Epileptic encephalopathy with continuous spike-and-wave during slow sleep (2021)
- Infant myoclonic epilepsy (2019)
- Sturge Weber Syndrome – co-authored with the rare diseases health sector FIMARAD (in preparation)

Sturge-Weber syndrome: causes, symptoms, evolution, everything you need to know about this rare pathology
Doctissimo | 06.23.2023
A congenital vascular disease affecting the skin and nervous system, Sturge-Weber syndrome is characterized by abnormal growth of small blood vessels. It manifests as a flat angioma of the face, a leptomeningeal angioma and possible neurological damage. Prof. Rima Nabbout, pediatric neurologist and coordinator of the CRéER (Reference center for rare epilepsies) at the Necker-Enfants malades hospital, tells us more about the management of this rare pathology.

September 25-27, 2024 – Workshop/Symposium: « How to improve the use of orphan drugs from pediatric to adulthood? »
As part of the work led by Prof. Rima Nabbout’s team, in close collaboration with the Rare Diseases Reference Center (CRMR) teams, special attention is being given to the transition and transfer of care for patients with developmental and epileptic encephalopathies (DEE) as they move into adult healthcare services. This process presents significant challenges, particularly due to the lack of awareness among adult practitioners regarding recently identified DEE with genetic etiologies, as well as the difficulty of ensuring multidisciplinary care that addresses cognitive, psychiatric, and motor disorders, alongside social, educational, and societal needs.
To tackle these challenges, a meeting was organized under the framework of the transition working group coordinated by Prof. Nabbout within the International League Against Epilepsy. This event brought together over 20 physicians and researchers, 8 patient associations, and 4 pharmaceutical industry representatives. Participants shared experiences and solutions to empower patients, families, and both pediatric and adult neurologists, aiming to ensure a smooth and coordinated transition.
These discussions laid the groundwork for improved collaboration among stakeholders and identified strategies for more tailored and effective care during this critical stage of the patient care journey.

July 2, 2024 – Innov4-ePiK: A New Approach for Developmental and Epileptic Encephalopathies
Coordinated by Institut Imagine (Inserm, AP-HP, Université Paris Cité), the Innov4-ePiK project aims to revolutionize the diagnosis and treatment of rare developmental and epileptic encephalopathies through 4P medicine (Personalized, Predictive, Preventive, Participatory).
Supported by €9.9 million in funding, it brings together 10 partners to develop diagnostic tools, biomarkers, and innovative therapies, offering personalized solutions for patients.
