Filter by:Epilepsy with centrotemporal spikes (ECTS) is the most common epilepsy syndrome in children. Language impairment has been widely investigated in patients with ECTS, but little is known about the cognitive dysfunction of processing speed and its neuroimaging mechanism.
Rolandic 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.
The 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.
This original article is a novel investigation on the metabolic characteristics of different patterns of antiepileptic drug (AED) responses in benign epilepsy with centrotemporal spikes (BECTS) patients using 18F-FDG PET imaging. In this study, we demonstrated remitting-relapsing group showed more widespread hypo-metabolism regions than AED responders. Results indicated that metabolic differences had the ability to distinguish the remitting-relapsing patients from AED responders. 18F-FDG PET could be used as a marker to infer the current seizure activity of BECTS. We think that the established hybrid model based on PET and clinical features may be a critical reference for better personalized medication in patients with BECTS.
Benign 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
Age 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
We have discovered a small change in the genetic code which increases the risk of the brainwave abnormality that is found in rolandic epilepsy. We now wish to confirm this using a second much larger sample of patients. We will investigate the other genetic changes that cause people with the brainwave abnormality to develop seizures, as well as problems with speech, coordination, attention and learning.
Benign 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.
The social processes depend on complex cognitive mechanisms, which involve mainly the frontal and temporal lobe regions. Patients with early onset frontal and temporal lobe lesions might later develop important deficits in social integration. Accordingly, children with early onset temporal lobe epilepsy (TLE) demonstrate altered emotion recognition.
This 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.
