A wealth of animal and human research has pointed to a significant involvement of the temporal lobes in memory processing, and yet the different functional roles of temporal cortical vs. mesial structures remain unclear. We studied verbal declarative memory, by using a word list paradigm that differentiates among learning (immediate recall), memory (delayed(More)
OBJECTIVES Existing speculations regarding the cognitive functions of the right hippocampus suggest a special involvement in non-verbal memory functions. However, all supporting evidence in epileptic patients came from postoperative studies that did not consider the preoperative functioning level. The present study investigates in patients with right(More)
The purpose of our study is to evaluate whether children recover better than adults from memory deficits as a consequence of temporal lobe surgery. We compared 3 and 12 month outcomes obtained in children and adults with medically refractory epilepsy. Each candidate underwent temporal lobe resection for seizure control and children were matched with regard(More)
We report the effects of hippocampal and non-hippocampal temporal-lobe dysfunction on verbal fluency performance. Quantitative aspects of semantic and phonemic fluency performance were examined in 46 patients with right- or left-temporal-lobe epilepsy and 20 healthy controls. A pattern of fewer words generated on semantic rather than phonemic fluency tasks(More)
BACKGROUND AND AIMS Mediotemporal lobe (MTL) epilepsy (MTLE) is particularly frequent among human localisation related epilepsies. MTLE usually starts before adulthood and is most frequently associated with hippocampal sclerosis (HS). Here, aetiologies, disease courses and outcomes of adult onset MTLE patients treated at this tertiary epilepsy centre are(More)
PURPOSE The technique of selective amygdalohippocampectomy (SAH) was originally developed in epilepsy surgery to spare unaffected brain tissue from surgery, thus minimizing the cognitive consequences of temporal lobe surgery. The results of previous studies, however, are equivocal in this regard. This study evaluated memory after SAH in a large sample of(More)
Weak relationships have been reported between subjective complaints of memory deficits and memory performance in neuropsychological tests in patients with temporal lobe epilepsy (TLE). This study investigated whether the individual exposure to cognitive demands in daily life contributes to cancel out the performance-complaint relationship in such a way that(More)
Seven patients with Rasmussen encephalitis (RE) were treated with the immunosuppressant tacrolimus and followed for a median of 22.4 months. They were compared with 12 historical untreated RE patients (median follow-up 13.9 months). The tacrolimus-treated patients had a superior outcome regarding neurologic function and progression rate of cerebral(More)
OBJECTIVE Hemispheric neurosurgery is an established treatment for severe epilepsy caused by extended unilateral brain pathology. However, it is still an unresolved question at which age surgery should best be performed. In light of decreasing plasticity and the cumulative impact of seizures and anticonvulsants on neurodevelopment, early surgery appears(More)
