Focal cortical dysplasias (FCDs) are increasingly diagnosed as a cause of symptomatic focal epilepsy in paediatric and adult patients. However, little is known about the clinical characteristics of epilepsy in these patients. In order to elucidate the clinical characteristics of their epilepsy, 120 pharmacoresistant patients including children and adults(More)
OBJECTIVE Focal cortical dysplasia (FCD) is currently recognized as the most common cause of neocortical pharmacoresistant epilepsy. Epilepsy surgery has become an increasingly successful treatment option. Herein, the largest patient cohort reported to date is analyzed regarding long-term outcome and factors relevant for long-term seizure control. METHODS(More)
Depth recordings in patients with Parkinson's disease on dopaminergic therapy have revealed a tendency for oscillatory activity in the basal ganglia that is sharply tuned to frequencies of approximately 70 Hz and increases with voluntary movement. It is unclear whether this activity is essentially physiological and whether it might be involved in arousal(More)
Cardiac bradyarrhythmias may play a pivotal role in the pathophysiology of sudden unexpected death in epilepsy (SUDEP). We describe a patient with left temporal lobe epilepsy in whom high-grade atrioventricular conduction blocks were triggered by both spontaneous and stimulation-induced epileptic activity in the left temporal lobe. Electrophysiological data(More)
PURPOSE To evaluate the potential diagnostic value of a novel magnetic resonance image (MRI) postprocessing technique in subtle forms of subcortical band heterotopia (SBH). The method was introduced to improve the visualization of blurred gray-white matter junctions associated with focal cortical dysplasia but was found to be applicable also to SBH. (More)
The epileptologically informed in-depth analysis of auto- and heteroanamnestic historical sources supports the hypothesis that Hector Berlioz (1803-1869) might have suffered from a photosensitive idiopathic generalized epilepsy syndrome with absences, absence status, myoclonic seizures, and bilateral tonic-clonic seizures. The study outlines the possible(More)
OBJECTIVE Information on the relative timing of electroencephalography (EEG) seizure onset, ictal tachycardia (ITC), and first other clinical seizure manifestations is crucial for an understanding of the potential benefit of ITC-detection based closed-loop intervention systems for epilepsy treatment. This study analyzes the temporal relation of ITC, other(More)
Curvilinear reformatting of three-dimensional (3D) MRI data of the cerebral cortex is a well-established tool which improves the display of the gyral structure, permits a precise localization of lesions, and helps to identify subtle abnormalities difficult to detect in planar slices due to the brain's complex convolutional pattern. However, the method is(More)
PURPOSE To assess the efficacy and tolerability of chronic high-frequency deep brain stimulation (DBS) in adult patients with progressive myoclonic epilepsy (PME) syndromes. METHODS Five adult patients (four male, 28-39 years) with PME underwent chronic high-frequency DBS according to a study protocol that had been approved by the local ethics committee.(More)
