Our knowledge of longer term outcome in psychogenic nonepileptic seizures (PNESs) patients is limited; we know less still about factors predicting prognosis. This study was intended to describe outcome in a large cohort and to identify predictive clinical and psychological factors to generate new ideas for treatment. One hundred sixty-four adult patients(More)
Cognitive profiles in epilepsy are as heterogenous as the epileptic syndromes themselves; causes, topography of epileptogenic areas, pathogenetic mechanisms, and the diverse features characterising the clinical course all contribute to the effect on cognition. Chronic epilepsy generally impairs cognition, but it also induces processes of functional(More)
Previous studies have shown that left temporal lobectomy for intractable epilepsy can lead to verbal memory deficits. However, patients with left temporal lobe epilepsy (LTLE) frequently have impaired verbal memory preoperatively. The present analysis of 144 patients who underwent temporal lobe resections for either left (n = 68) or right (n = 76) temporal(More)
Myotonic dystrophy types 1 and 2 are progressive multisystemic disorders with potential brain involvement. We compared 22 myotonic dystrophy type 1 and 22 myotonic dystrophy type 2 clinically and neuropsychologically well-characterized patients and a corresponding healthy control group using structural brain magnetic resonance imaging at 3 T(More)
It remains unclear whether uncontrolled epilepsy causes mental decline. This longitudinal study contrasts change of memory and nonmemory functions in 147 surgically and 102 medically treated patients with temporal lobe epilepsy. All participants were evaluated at baseline (T1) and after 2 to 10 years (T3). Surgical patients underwent additional testing 1(More)
Depression is a frequent psychiatric symptom in epilepsy and has been related to epilepsy of temporal origin, especially of left-sided foci. No study differentiated the precise localization of the epileptogenic lesion within the temporal lobe. Regarding this issue, we evaluated depression assessed by the Beck Depression Inventory in 60 patients with(More)
Animal experiments and lesion studies have shown the importance of temporal lobe structures for language and memory. We recorded intracranial cognitive potentials from the human lateral and medial temporal lobe in 26 patients with temporal lobe epilepsy undergoing presurgical evaluation, using a word- and a picture-recognition paradigm. Neuropsychological(More)
PURPOSE In a previous study we reported clinically significant memory declines 3 months after selective amygdalohippocampectomy (SAH) in 140 patients with mesial temporal lobe epilepsy, particularly if the resection was left-sided. We supposed that the observed postoperative impairments might have reflected acute effects of surgery. Therefore we evaluated(More)
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)
While most neuropsychological studies in focal epilepsies are concerned with temporal lobe epilepsy (TLE), only few investigations aim cognitive functioning in unresected patients with frontal lobe epilepsy (FLE). Following functional models arising from lesional studies, we evaluated patients with TLE (21 left, 17 right) and FLE (6 left, 17 right) with(More)
