Focal cortical dysplasias (FCD) which represent a composite group of cortical malformations are increasingly recognized as morphological substrate for severe therapy-refractory epilepsy in children and young adults. However, presurgical evaluation remains challenging as not all FCD variants can be reliably detected by high-resolution magnetic resonance(More)
Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon application of the dopamine uptake inhibitor nomifensine. The acetylcholine esterase inhibitor eserine(More)
The actions of opioid receptor agonists on stimulus evoked dopamine overflow in rat neostriatal slices were investigated using fast cyclic voltammetry. Activation of delta and mu receptors reversibly depressed striatal dopamine efflux induced by intrastriatal stimulation. The inhibitory effect of DADLE (D-Ala2, D-Leu5-enkephalin, delta/mu agonist), DPDPE(More)
OBJECTIVE To analyze and to discuss whether by paying attention to the many recent advancements in the field of pediatric epilepsy surgery catastrophic childhood epilepsies caused by definitive or suspected structural lesions can be prevented more often these days in comparison to the past. METHODS Based on data from the literature and supplemented by the(More)
Focal Cortical Dysplasias (FCDs) present with a large clinicopathological spectrum. FCDs are believed to relate directly to an epileptogenic condition, although seizure control by surgical resection is variable. This applies in particular to young children with multilobar FCDs, suffering from severe epilepsies and psychomotor retardation. Herein, we(More)
The histopathological spectrum of human epileptogenic brain lesions is widespread including common and rare variants of cortical malformations. However, 2-26% of epilepsy surgery specimens are histopathologically classified as nonlesional. We hypothesized that these specimens include also new diagnostic entities, in particular when presurgical magnetic(More)
Patients with hemispheric malformations of cortical development (such as polymicrogyria) often develop medically intractable epilepsies for which hemispherotomy can be an excellent treatment option. Transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) are noninvasive methods used to evaluate the sensorimotor system in(More)
In recent years, intrathecal baclofen (ITB) has attained an important role in the treatment of severe spasticity and dystonia in children. There are principal differences between the use of ITB in children and its use in neurology and oncology in adults. Here, we present a consensus report on best practice for the treatment of severe spastic and dystonic(More)
Hemidisconnections (i.e. hemispherectomies or hemispherotomies) invariably lead to contralateral hemiparesis. Many patients with a pre-existing hemiparesis, however, experience no deterioration in motor functions, and some can still grasp with their paretic hand after hemidisconnection. The scope of our study was to predict this phenomenon. Hypothesizing(More)
Breast cancer resistance protein (BCRP) functions as a major molecular gatekeeper at the blood-brain barrier. Considering its impact on access to the brain by therapeutic drugs and harmful xenobiotics, it is of particular interest to elucidate the mechanisms of its regulation. Excessive glutamate concentrations have been reported during epileptic seizures(More)
