Description du projet
Une cartographie précise des changements sous-corticaux dans l’épilepsie focale
L’épilepsie focale est une maladie neurologique caractérisée par des crises qui commencent dans une ou plusieurs régions et se propagent ensuite rapidement dans le cerveau. De nombreuses recherches se sont concentrées sur la matière grise externe, mais nous savons désormais que les structures cérébrales internes, sous-corticales, sont également impliquées dans les crises. Pourtant, l’effet exact de l’épilepsie focale sur la matière grise sous-corticale est resté relativement peu étudié. Avec le soutien du programme Actions Marie Skłodowska-Curie, le projet SUCCEED utilisera des données d’imagerie à haute résolution et multimodales acquises par IRM à 7 T pour caractériser les altérations sous-corticales chez des patients atteints d’épilepsie focale.
Objectif
Focal epilepsy is a chronic neurological disorder characterized by repeated spontaneous seizures that originate from one or several confined regions. After onset, these seizures often propagate towards networks of regions spread across the brain, negatively affecting whole-brain dynamics and cognitive functioning in these patients. Despite evidence advocating the involvement of subcortical areas in seizure organisation in some patients, the exact mechanisms are still poorly understood. Therefore, I anticipate that multimodal, high resolution characterization of the subcortex using 7 Tesla MRI data provides an important, missing link to enhance our understanding of changes within, and differences between focal epilepsy patients. I will explore this in three aims that focus on network integrity, tissue integrity and disease heterogeneity. Successful completion of the objectives is maximized by a two-way transfer of knowledge by combining my proficiency in quantitative brain mapping and computational neuroimaging with the host’s expertise related to brain network analyses in epilepsy. Together these techniques provide a platform for ‘SUbCortical Characterization to Enhance Epilepsy Differentiation’ (SUCCEED) and will advance the development of non-invasive subcortical biomarkers towards personalized diagnosis and treatment of focal epilepsy. Results will be communicated to the scientific and non-scientific public through scientific publications, conference presentations, via Twitter, workshops and open days. With the host lab situated at the forefront of epilepsy research, it will provide the ideal environment to improve my scientific network, and receive the relevant technical and personal training. Together with the innovative and interdisciplinary nature of the project, this will give me the unique opportunity to mature further towards an independent researcher both during and after the fellowship.
