Official title
Developmental and Epileptic Encephalopathy of Genetic Etiology: Natural History Through Reuse of Clinical Data / DEE-RETRO
Overview
Developmental and Epileptic Encephalopathy (DEE) are a heterogeneous group of neurodevelopmental disorders linked to both epilepsy and its underlying etiology, independently of epileptiform activity. The creation of a database with retrospective follow-up of a large number of patients on a national scale will enable better knowledge of specific biomarkers, and thus a better classification and understanding of the natural evolution of DEE according to their etiology. This will enable better, more personalized therapeutic management of patients, depending on etiology and the presence or absence of these biomarkers. The investigators will also be able to draw up management recommendations, which are currently non-existent.
Primary outcome measures
- Identification of diagnostic and early predictive biomarkers of a neurodevelopmental trajectory with epileptic and developmental encephalopathies [Time frame: Data 2002-2026]
Secondary outcome measures (5)
- Identification of patient subgroups presenting the identified biomarkers [Time frame: Data 2002-2026]
- Assessment of patients' quality of life [Time frame: Data 2002-2026]
- Assessment of age-related adaptive behavior [Time frame: Data 2002-2026]
- Assessment of behavioral disorders [Time frame: Data 2002-2026]
- Assessment of autism spectrum disorders [Time frame: Data 2002-2026]
