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)
Numerous patients who are prescribed antiepileptic drugs (AEDs) for epileptic seizures are already receiving other agents for the treatment of co-morbid conditions, which frequently occur alongside epilepsy. This raises additional clinical considerations and makes the use of AEDs with good safety profiles and fewer drug-drug interactions attractive. Second(More)
Alzheimer's disease (AD) depicts dynamic changes in regional brain function from early stages of the disease. Arterial spin labeling- (ASL-) based MRI methods have been applied for detecting regional cerebral blood flow (rCBF) perfusion changes in patients with AD and mild cognitive impairment (MCI). Nevertheless, the results obtained from ASL studies in AD(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)
