OBJECTIVE To investigate the efficacy and safety of once-daily eslicarbazepine acetate (ESL) when used as add-on treatment in adults with > or = 4 partial-onset seizures per 4-week despite treatment with 1 to 3 antiepileptic drugs (AEDs). METHODS This double-blind, parallel-group, multicenter study consisted of an 8-week observational baseline period,(More)
Background and Purpose: The purpose of this study was to analyse in detail the functional outcome and the neuropsychological deficits in patients with space-occupying infarction of the non-dominant hemisphere one year after surgery. Methods: Postoperative complications and retrospective consent to surgery were assessed in a semi-structured interview in 26(More)
PURPOSE To identify and characterize the mutation(s) causing nocturnal frontal lobe epilepsy in a German extended family. METHODS Neuronal nicotinic acetylcholine receptor (nAChR) subunit genes were screened by direct sequencing. Once a CHRNA4 mutation was identified, its biophysical and pharmacologic properties were characterized by expression(More)
From 1987 to 1992, invasive EEG studies using subdural strips, grids or depth electrodes were performed in a total of 160 patients with medically intractable epilepsy, in whom scalp EEG was insufficient to localize the epileptogenic focus. Dependent on the individual requirements, these different electrode types were used alone or in combination. Multiple(More)
Pilocarpine-induced status epilepticus (PCSE) is a widely used model to study neurodegeneration in limbic structures after prolonged epileptic seizures. However, mechanisms mediating neuronal cell death in this model require further characterization. Examining the expression time course and spatial distribution of activated caspase-3, we sought to determine(More)
OBJECTIVE To evaluate the long-term safety, tolerability and efficacy of once-daily eslicarbazepine acetate (ESL) as adjunctive therapy in adults with partial-onset seizures. METHODS One-year open-label extension (OLE) study with ESL in patients who completed a randomised, double-blind placebo-controlled trial (study BIA-2093-302; Epilepsy Res. 89 (2010)(More)
During the last decade multiple work has been done to determine the sources of epileptiform activity by means of dipole source localization based on recordings of the magnetoencephalogram (MEG) or the electroencephalogram (EEG). The actual available advanced volume conductor models and the multiple source reconstruction by regularization may give new(More)
Nicotinic acetylcholine receptors (nAChRs) are involved in a familial form of frontal lobe epilepsy, autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE). In several ADNFLE families, mutations were identified in the nAChR alpha4 or beta2 subunit, which together compose the main cerebral nAChR. Electrophysiological assessment using in vitro expression(More)
PURPOSE Headache is often ignored as a symptom of epileptic seizures. The purpose of this prospective study was to analyze frequency, classification, and characteristics of seizure-associated headache (SH) according to the criteria of the International Headache Society. METHODS Over a period of 15 months, 341 patients with epilepsy, consecutively(More)
Transient elevation of serum levels of prolactin has been observed following several types of epileptic seizures and after electrical stimulation of limbic temporal lobe structures via implanted electrodes. Transcranial magnetic stimulation has been found to selectively induce epileptiform afterdischarges in the epileptic focus of candidates for epilepsy(More)
