Filter by:The purpose of this study is to determine whether omega-3 is effective in the treatment of medically intractable epilepsy as adjunctive therapy.
Brain somatic mutations in genes belonging to the mTOR signaling pathway are a frequent cause of cortical malformations, including focal cortical dysplasia or hemimegalencephaly. The present study aims to search for brain somatic mutations in paired blood-brain samples and perform functional validation in children with drug-resistant focal epilepsy
Increasing evidences showed the microbiota effects on neuropsychiatric disorders. This clinical trial aims to evaluate the efficacy and safety of fecal microbiota transplantation for epilepsy.
When focal epilepsies become drug-resistant, it could be eligible for cortical surgical resection. Therefore, an invasive EEG monitoring with depth electrodes is often needed during presurgical evaluation. Some of these children can have access to thermocoagulation inside the ictal onset zone, at the end of the monitoring and before to remove the electrodes. These thermocoagulations can disorganize the epileptogenic network thanks to millimetric cortical lesions around the electrodes. The aim is to stop or at least, to reduce the seizure frequency for few weeks or months. This could be a benefit for the child, and also a confirmation of the ictal onset zone and guide the surgeon. This technique is currently used in adult population for years, but remains very rare in children.
The knowledge of encephalitis associated with antibodies targeting intracellular antigens, and neuronal surface antibody syndromes has expanded considerably in recent times. The primary purpose of the investigators protocole is to determine the incidence of anti-neuronal antibodies (blood and CSF) in a population of patients suffering from focal epilepsy of unknown cause to guide the management of these patients. The investigators hypothesis is that dysimmune encephalitis is more common than is suggested by the current literature, and that sometimes forms of encephalitis dysimmune "at minimum" can be observed only in the form of focal epilepsy without further manifestation associated.
The purpose is to evaluate specific capacities of face detection of individual neurons by comparison with their capacity of object detection in medial temporal lobe and ventral temporal cortex in epileptic patients. Secondary purpose is to evaluate specific capacities of detection of known faces of individual neurons by comparison with their capacity of detection of unknown faces in medial temporal lobe and ventral temporal cortex in epileptic patients.
Electroencephalograhy (EEG) is used as a tool for diagnosing epilepsy/convulsions. During the recording, especially for childen who are suspected of having abbcence epilepsy the investigators will perform an EEG recording including a provocation test of hyperventilation in order to induce epileptic discharges. There is no clear instruction about the position of the child during performing this hyperventilation provocation. Clinical observations showed that this provocation is more effective when it's performed in the siiting position. No study was previously performed to investigate this issue
To determine the utility of diffusion tensor magnetic resonance imaging in the preoperative workup of children with intractable epilepsy referred for surgery.
Epilepsy is a devastating chronic disease due to multiple causes that affect close to 50% of the world's population. Although effective, epilepsy surgery fails in many cases, the percentage of patients free from crisis on a long term (≥ 5 years) varies from 27% to 66% according to the kind of epilepsy. It is in this context that EPISTIM is interesting, and its aims isb a better electrophysiology delimiting of cortical networks that imply the genesis of seizures with the aim to improove surgery results. This study will rely on the intracerebral records and on corticales electrical stimulation as they are currently routinely used by epileptic patients candidates for surgery.
Epilepsy in children is a major public health issue. It is the first neurological disease of the child.
