PURPOSE Simultaneous interictal EEG and magnetoencephalography (MEG) recordings were used for noninvasive analysis of epileptogenicity in focal cortical dysplasia (FCD). The results of two different approach methods (multiple source analysis of averaged spikes and single dipole peak localization of single spikes) were compared with pre- and postoperative(More)
When evaluating interictal spikes using dipole source analysis it is important to account for multiple sources and the overlapping background EEG. Analyses of spike peaks may be modeling only propagated sources. Careful filtering of averaged spike data and multiple source analysis can provide useful information about the onset of epileptiform activity. A(More)
The comparative sensitivity of EEG and magnetoencephalography (MEG) in the visual detection of focal epileptiform activity in simultaneous interictal sleep recordings were investigated. The authors examined 14 patients aged 3.5 to 17 years with localization-related epilepsy. Simultaneous 122-channel whole-head MEG and 33-channel EEG were recorded for 20 to(More)
The purpose of this study was to assess whether the histological subtype of focal cortical dysplasia and dual pathology affect surgical outcome in patients with medically intractable epilepsy due to focal cortical dysplasia (FCD). We retrospectively analysed the outcome of 67 patients from 2 to 66 years of age at follow-up periods of 6 to 48 months after(More)
Rhombencephalosynapsis is a rare congenital abnormality characterised by dorsal fusion of the cerebellar hemispheres, agenesis or hypogenesis of the vermis, fusion of dentate nuclei and superior cerebellar peduncles. We describe 9 children, aged 1.5 to 6 years, with rhombencephalosynapsis. Isolated rhombencephalosynapsis was found in 2 patients,(More)
OBJECTIVE The aim of the study was to explore the effectiveness and tolerability of rufinamide in a heterogeneous group of patients with refractory epilepsies in Europe, immediately after the drug became available as an orphan drug for the adjunctive treatment of Lennox-Gastaut syndrome (LGS). METHODS This observational study was conducted as a collection(More)
A total of 120 patients with histologically proven focal cortical dysplasias (FCD) were retrospectively analysed for prognostic factors for successful epilepsy surgery. Multivariate data analyses showed that older age at epilepsy surgery, occurrence of secondarily generalised seizures and a multilobar extent of the dysplasia were significant negative(More)
OBJECTIVE Recently, we published the first postmarketing European experience with rufinamide (RUF) in a retrospective 12-week observational study. This follow-up report summarizes the long-term effectiveness and tolerability of RUF after 18 months for the same patient sample. METHODS In total, 52 of 60 initially included patients from eight centers in(More)
PURPOSE To evaluate the effects of sulthiame (Ospolot; STM) monotherapy compared with placebo on the EEG in children with benign childhood epilepsy with centrotemporal spikes (BECTS). METHODS Sixty-six patients (aged 3-11 years) entered a 6-month double-blind trial and were randomized to either STM (n = 31) or placebo (n = 35). Clinical data and general(More)
PURPOSE To gain new insights into the clinical presentation, causes, treatment and prognosis of epilepsia partialis continua (EPC), and to develop hypotheses to be tested in a prospective investigation. METHODS In this retrospective multicenter study, all cases were included that fulfilled these criteria: constantly repeated fragments of epileptic(More)
