The experimental antiepileptic drug, levetiracetam (UCB L059), a piracetam analogue has been investigated in photosensitive patients in the "photosensitivity model", an early phase II study. A total of 12 patients (10 females, 2 males) with a mean age of 21.5 years (range 13-38) were investigated during a 3 day period in 3 centres (France, The Netherlands,(More)
A technique to record from the mesio-basal aspect of the temporal lobe by a subdural electrode inserted through the foramen ovale (FO) is described. For this purpose a special electrode was developed that, in addition, allowed epicortical DC recording. After having tested its value experimentally in dogs with penicillin-induced hippocampal seizure foci,(More)
Several reports have described that a positive vertex peak of an evoked potential varied in amplitude and latency specifically when images of faces were the eliciting stimulus. The scalp topography and the possible underlying dipole sources of this peak are the subject of this report. We presented black-and-white photographs of human faces, flowers and(More)
Mnestic deficits represent the core cognitive impairment of patients with temporal lobe epilepsy (TLE), irrespective of the existence of overt morphological lesions. Compared to controls, patients with symptomatic TLE show altered functional activation patterns in fMRI studies on memory processes. But, so far, such studies have rarely investigated patients(More)
Near Infrared Spectroscopy (NIRS) was employed to noninvasively and continuously (temporal resolution 0.5 s) assess changes in cerebral hemodynamics and oxygenation during various functional states of the adult human brain. During cognitive stimulation (performing calculations) a frontal increase in local cerebral blood volume and oxygenated hemoglobin(More)
The effect of acute treatment with the new antiepileptic drug (AED) levetiracetam (Keppra) on the frequency of interictal epileptiform discharges (IEDs) was evaluated in a double-blind, placebo-controlled, crossover study with therapeutic drug monitoring and serial electroencephalographic (EEG) observations. Acute (500 mg twice daily) and chronic(More)
OBJECT The authors propose a novel surgical approach for amygdalohippocampectomy (AH) in patients with temporal lobe epilepsy. Via a transsylvian-transcisternal route, the parahippocampal gyrus is directly exposed from its medial aspect, thus allowing a standardized en bloc resection of the temporomesial epileptogenic structures--the amygdala, anterior(More)
Transcranial magnetic stimulation (TMS) of the human brain is mainly used for the diagnosis of diseases with disturbed central motor conduction. Recent studies revealed controversial results concerning the possibility of a TMS-induced specific activation of epileptogenic foci in patients with localization-related epilepsies, which would make TMS an(More)
Oxcarbazepine (OXC) is considered to be a promising new antiepileptic drug with similar efficacy and better tolerability compared to carbamazepine (CBZ). However, hyponatremia is supposed to occur even more often than with CBZ. We report on a patient who developed hyponatremic coma under OXC with a serum sodium level of 115 mmol/l, the second published case(More)
