Sleep Related Memory Consolidation in Children With Age Related Focal Epilepsy.
Benign Epilepsy With Centro Temporal Spikes (BECTS)Atypical Benign Partial Epilepsy (ABPE)1 moreAge related focal epilepsies in children encompasses, according to the ILAE criteria, benign epilepsy with centro temporal spikes (BECTS), atypical benign partial epilepsy (ABPE) and epileptic encephalopathy with continuous spike and waves during sleep (ECSWS). These non structural epilepsies are associated with interictal sleep spike and waves activated by sleep. Moreover, high prevalence of learning disorders occur in children with age related epilepsies. A correlation is suspected between learning disorders and sleep activation of spike and waves. The investigators suppose that learning dysfunction is linked to loss of information during sleep of epileptic children, unlike for control patients. As sleep allows memory consolidation of words learned during wakefulness, an epileptic activity during sleep may disrupt this consolidation, leading to a loss of information. Hypothesis: the investigators hypothesize a disruption of memory consolidation after one night in children affected with ABPE and ECSWS (severe group) compared to memory consolidation in children affected with BECTS (benign group), and control group. Primary purpose: To demonstrate that the deficit of delayed recall in 15 word learning test after one night is higher for the "severe group", compared to the "benign group" and the control group. Secondary purposes: to study the evolution over time of memory consolidation to evaluate the correlation of the deficit of delayed recall with executive dysfunction, clinical factors of epilepsy, neurophysiological factors of epilepsy, and sleep architecture
Transcranial Magnetic Stimulation for BECTS
Benign Epilepsy With Centrotemporal SpikesLanguage Problems1 moreBenign epilepsy with centrotemporal spikes (BECTS) is the most common pediatric epilepsy syndrome. Affected children typically have a mild seizure disorder, but yet have moderate difficulties with language, learning and attention that impact quality of life more than the seizures. Separate from the seizures, these children have very frequent abnormal activity in their brain known as interictal epileptiform discharges (IEDs, or spikes), which physicians currently do not treat. These IEDs arise near the motor cortex, a region in the brain that controls movement. In this study, the investigators will use a form of non-invasive brain stimulation called transcranial magnetic stimulation (TMS) to determine the impact of IEDs on brain regions important for language to investigate: (1) if treatment of IEDs could improve language; and (2) if brain stimulation may be a treatment option for children with epilepsy. Participating children will wear electroencephalogram (EEG) caps to measure brain activity. The investigators will use TMS to stimulate the brain region where the IEDs originate to measure how this region is connected to other brain regions. Children will then receive a special form of TMS called repetitive TMS (rTMS) that briefly reduces brain excitability. The study will measure if IEDs decrease and if brain connectivity changes after rTMS is applied. The investigators hypothesize that the IEDs cause language problems by increasing connectivity between the motor cortex and language regions. The investigators further hypothesize that rTMS will reduce the frequency of IEDs and also reduce connectivity between the motor and language region
Sleep Spindles and Memory in Rolandic Epilepsy
Rolandic EpilepsyRolandic Epilepsy6 moreThe investigators are recruiting children with Rolandic epilepsy and children without epilepsy (aged 4 years old and above) for a non-invasive brain imaging study using Magnetic Resonance Imaging (MRI), Magnetoencephalography/Electroencephalography (MEG/EEG), and experimental tasks. The investigators hope to determine the brain circuits and brain rhythms affected in these children and ultimately identify new treatment options for childhood epilepsy patients.
HEAD-Study Optimizing the Treatment of Children With BECTS
EpilepsyRolandicThe investigators hypothesize that Levetiracetam is as effective as Sulthiame in the treatment of children with BECTS. Patients entering the HEAD-Studie are either treated with Leveitracetam or Sulthiame over a 6 months period. Patients are equally randomised to one of the two treatment regimens. Administration of medication as blinded capsules.
Imaging the Effect of Centrotemporal Spikes and Seizures on Language in Children
Benign Childhood Epilepsy With Centro-Temporal SpikesThis project examines how seizures, and abnormal brain activity, affect language skill in children with Benign Childhood Epilepsy with Centro-Temporal Spikes (BECTS). BECTS is a common type of childhood epilepsy, and while BECTS patients stop having seizures by their late teenage years, many studies have shown that these children have language problems that may lead to academic and social difficulties. Using standardized language testing, monitoring of brain activity, and MRI brain imaging, this project aims to determine what particular combination of BECTS symptoms put children most at risk for language problems and whether treatment with anti-epileptic medications may be helpful.
Safety and Efficacy of Topamax Versus Carbamazepine in Benign Rolandic Epilepsy
EpilepsyRolandicThe purpose of this study is to determine the efficacy and safety of Topiramate in comparison to Carbamazepine in Benign rolandic epilepsy.
The Effect of Music Periodicity on Interictal Epileptiform Discharges
Rolandic EpilepsyBenign Childhood Epilepsy With Centrotemporal Spikes2 moreThe purpose of this study is to determine if having children listen to the music of Wolfgang Amadeus Mozart (Sonata for Two Pianos in D Major, K. 448) will lessen the amount of spike discharges on his/her Electroencephalography (EEG). These spike discharges often occur during a 24 hour period in the EEG of a child with Benign Childhood Epilepsy with Centrotemporal Spikes (BCECTS), or Rolandic Epilepsy. Should there be a decrease in the amount of spike discharges after listening to Mozart's music, this information may lead to new understanding and possible treatments for epilepsy.
Changing Agendas on Sleep, Treatment and Learning in Epilepsy
Rolandic EpilepsyRolandic epilepsy (RE) is the most common type of epilepsy. Children with RE have seizures and can often find that their learning, sleep, behaviour, self-esteem and mood are affected. As part of standard NHS care, children diagnosed with RE may be treated with standard anti-epileptic medicines, like carbamazepine, or no medicine at all. The medicines used to treat epilepsy often slow down a child's thinking and learning. In the past, doctors believed this was an acceptable price to pay to reduce seizures. However, with RE, where the seizures usually stop in teenage years, investigators do not know if it is better to treat these children with medicines or not, especially if the medicines might have a negative effect on their learning. A newer medicine called levetiracetam has also been found to work in children with RE and has shown less problems with thinking and learning in adults. However, it is still no known if this is also the case for children and it has not been proven which of the three options (carbamazepine, levetiracetam or no treatment) would be best for RE patients. The CASTLE study aims to find this out. In addition, it has been found that seizures often happen when a child has had poor sleep and they often come at night or early in the morning. It has been shown that sleep can be improved through practice without the need of medicines. There are established guidelines to help toddlers go to sleep, but nothing available that helps young people with epilepsy and their parents improve their sleep quality. In the CASTLE study, a sleep training plan has been developed for children with epilepsy and the trial aims to find out whether following this sleep training plan results in less seizures than using no sleep training at all.
Electroclinical Effect of Steroid in Patients With Benign Childhood Epilepsy With Centrotemporal...
Benign Childhood Epilepsy With Centrotemporal SpikesBenign epilepsy with centro-temporal spikes is the most common type of focal epilepsy in children. It is known to be age-dependent and presumably genetic. Age of onset ranges from one to fourteen years and it represents fifteen percent to twenty five percent of epilepsy in children under 15 years of age.
Brain Maturation in Children With Localization Related Epilepsy
Benign Childhood Epilepsy With Centro-temporal Spikes (BCECTS)Focal Cryptogenic Epilepsy of Childhood1 moreThis project intends to investigate children with idiopathic and cryptogenic localization related epilepsies, using a longitudinal assessment of structural and functional MRI data, in relation to neuropsychological evaluation. The rationale is primarily based on: 1) the frequent observation of selective cognitive dysfunctions in such children, the pathophysiology of which remains largely uncertain; 2) the recent major advances in the MRI investigation of brain maturation showing striking age and region dependant patterns. The primary hypothesis is that some children with localization related epilepsies suffer from altered maturation in the epileptic brain regions, and that this abnormal maturation affects their cognitive abilities. 100 children with localization related epilepsies and 100 matched controls will be prospectively enrolled during the first two years of the disease (for patients) and benefit from a comprehensive phenotypic and neuropsychological evaluation once a year for 5 years. The brain maturation of these children will be longitudinally assessed using structural and functional MRI, and correlated with neuropsychological data. Investigators hope to demonstrate that children with localization related epilepsies and cognitive dysfunctions suffer from an abnormal brain maturation in regions underlying the epileptic activity and the altered cognitive processes. The finding could partly bridge the gap between these two abnormalities and help better understand their interaction and respective dynamic. Once validated, the study of regional brain maturation in children with epilepsy might be further used as a reliable surrogate marker or predictor of associated cognitive dysfunction.
