INTRODUCTION Electroencephalography (EEG) has a central role in the outcome prognostication in subjects with anoxic/hypoxic encephalopathy following a cardiac arrest (CA). Continuous EEG monitoring (cEEG) has been consistently developed and studied; however, its yield as compared to repeated standard EEG (sEEG) is unknown. METHODS We studied a prospective(More)
OBJECTIVE To evaluate an automated seizure detection (ASD) algorithm in EEGs with periodic and other challenging patterns. METHODS Selected EEGs recorded in patients over 1year old were classified into four groups: A. Periodic lateralized epileptiform discharges (PLEDs) with intermixed electrical seizures. B. PLEDs without seizures. C. Electrical seizures(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)
BACKGROUND AND PURPOSE Locating the epileptogenic zone (EZ) in patients with neocortical epilepsy presents major challenges. Our aim was to assess the accuracy of arterial spin labeling (ASL), an emerging non-invasive magnetic resonance imaging (MRI) perfusion technique, to locate the EZ in patients with drug-resistant neocortical epilepsy. METHODS(More)
BACKGROUND AND PURPOSE Vagus nerve stimulation (VNS) has been reported to be a safe and effective treatment for drug-resistant epilepsy. The aim of this study is to describe the effect of VNS in patients with a history of repeated episodes of status epilepticus (SE) before implantation. METHODS From a total of 83 adult patients with drug-resistant(More)
INTRODUCTION The widespread application of magnetic resonance imaging (MRI) has brought with it an increase in the detection of alterations in the white matter of the central nervous system. AIM. To investigate the evolution of patients with no previous neurological symptoms, but in whom MRI findings are highly suggestive of multiple sclerosis (MS). (More)
BACKGROUND AND PURPOSE Statins display anti-inflammatory and anti-epileptogenic properties in animal models, and may reduce the epilepsy risk in elderly humans; however, a possible modulating role on outcome in patients with status epilepticus (SE) has not been assessed. METHODS This cohort study was based on a prospective registry including all(More)
This study aims to demonstrate the reliability of the diagnosis of epilepsy after a new onset seizure, supported by a detailed anamnesis and the complementary tests accessible at the emergency room (ER), such as CT-scan and video-EEG. It was a prospective study including 131 adult patients (55% males, medium age 52.42 (±21.5)[16-98] years-old, follow-up(More)
