UNLABELLED The aim of this study was to investigate if sequential analysis of BOLD signal changes induced by seizures is useful for preoperative identification of the site of seizure onset in patients with pharmaco-resistant focal epilepsy. METHOD We analyzed BOLD raw data from 5 patients with focal medically refractory epilepsy who experienced partial(More)
PURPOSE The aim of this study was to introduce a new approach for analysis of functional magnetic resonance imaging (fMRI) data in order to illustrate the temporal development of the blood oxygenation level-dependent (BOLD) signal changes induced by epileptic seizures. METHOD In order to sequentially analyze the fMRI images acquired during epileptic(More)
UNLABELLED The purpose of our study was to evaluate the performance and clinical usefulness of an automated injector system (AIS) that administers an automated injection for ictal SPECT after calculating the volume of tracer to be injected over time. METHODS To test the AIS, repeated injections were performed at different times after tracer preparation.(More)
The unfolding process of the blue copper protein rusticyanin has been studied from the structural and the thermodynamic points of view at two pH values (pH 2.5 and 7.0). When Rc unfolds, copper ion remains bound to the polypeptide chain. Nuclear magnetic resonance data suggest that three of the copper ligands in the folded state are bound to the metal ion(More)
PURPOSE To evaluate the usefulness of ictal electroencephalography (EEG)-combined functional magnetic resonance imaging ( MRI) (EEG-fMRI) in localizing epileptogenic zone in refractory neocortical focal epilepsy. METHODS From the EEG-fMRI database of our institution including 62 adult patients, 14 (age 18-46 years) experienced some ictal event during the(More)
PURPOSE The aim of this study was to apply sequential analysis of electroencephalography-functional magnetic resonance imaging (EEG-fMRI) data to study the cortical substrates related to the generation of the interictal epileptiform activity (IEA) in patients with pharmacoresistant extratemporal epilepsy. METHODS We analyzed fMRI data from 21 children,(More)
An open-label, experimental, prospective 5-month follow-up study was performed with 19 patients with psychogenic nonepileptic seizures and anxiety disorder and/or depression who were treated with venlafaxine. The authors held monthly visits and evaluated changes in baseline Hamilton Depression Rating Scale scores, Hamilton Anxiety Rating Scale scores, and(More)
We aim to investigate whether temporal origin of epilepsy increases the risk of developing a psychiatric disorder and more specifically a major depressive disorder. The lack of standardized diagnostic instruments and the methodologic differences between studies highlight the fact that this issue warrants further, systematic, study. Three-hundred eight(More)
INTRODUCTION Cognitive disorders are common in patients with epilepsy. Their aetiology is multifactorial, being affected by the type and location of the epileptogenic lesion, epileptic syndrome, type of seizures, age of onset, frequency and severity. Timely diagnosis and treatment can help to reduce their impact on the patient's quality of life. RESULTS(More)
Intrauterine growth restriction (IUGR) is associated with a high risk of abnormal neurodevelopment. Underlying neuroanatomical substrates are partially documented. We hypothesized that at 12 months preterm infants would evidence specific white-matter microstructure alterations and gray-matter differences induced by severe IUGR. Twenty preterm infants with(More)
