Impact of Epileptic Discharge on the Structural Connectivity of the Developing Brain

Focal epilepsy is associated with widespread alterations in structural brain connectivity, often present at the disease onset and related to learning disabilities. Whether ongoing seizure activity contributes to network pathology is a matter of debate. This study intends to measure the impact of seizures on structural connectivity on a local and on a global level. In children examined with intracerebral electrodes to evaluate whether a surgical cure can be proposed, we combine intracerebral stereotactic electroencephalography (EEG) recordings with diffusion weighted imaging of white matter fibers. On the local level, the study will quantify the number of deficient connections in the seizure onset zone. On a global level, the study will compare the white matter fibers of the left and right hemisphere to probe whether physiological language lateralization is preserved.

Home Ultra-long Term EEG Monitoring for Rare Epilepsies and Developmental and Epileptic Encephalopathies

With this study the Investigator expects to develop a precise patient-centered model of care by means of home ultra-long-term EEG monitoring with a minimally invasive wearable EEG device (sqEEG). The following aims will be pursued: 1. to assess the sensitivity, reliability, and safety of sqEEG to record seizures over prolonged periods; 2. to verify sensitivity and reliability of automated seizure detection algorithms and to assess circadian and ultradian seizure/interictal epileptic discharges; distribution for the development of personalized seizure action plan; 3. to evaluate whether data collected with sqEEG can improve the clinical management of the patients and treatment outcomes. The investigator expects to use this wearable at-home EEG device to obtain an objective quantification of electrographic and electro-clinical seizures over a twelve-week period up to twenty-four weeks at home. The precise quantification of seizures is essential for a tailored treatment approach and to effectively monitor the response to treatment adjustments. The potential innovation of this approach relies on the possibility of managing the patient at home, reducing the side effects related to hospitalization and objectively quantifying the disease burden in the real-life setting with the aim of improve globally the patients' quality of life.
