The effect of executive function on health related quality of life in children with self-limited epilepsy with centrotemporal spikes.

Aim: The current study aims to investigate the effect of Executive Functions (EFs) on Health Related Quality of Life (HRQoL) in a cohort of children with self-limited epilepsy with centrotemporal spikes (SeLECTS) and to identify possible factors that impact HRQoL specifically related to epilepsy-related variables and EFs skills.

Material And Method: The Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL) and The Behavior Rating Inventory of Executive Function (BRIEF-2 and BRIEF-P) were completed by the parents of 129 patients with SeLECTS.

WISC-IV intellectual profiles in Italian children with self-limited epilepsy with centrotemporal spikes.

Objective: This study aimed to describe the intellectual profile based on the Wechsler Intelligence Scale for Children 4th edition (WISC-IV) in children with self-limited epilepsy with centrotemporal spikes (SeLECTS), with an attempt to define possible predictive epilepsy-related variables of cognitive performance.

Methods: The WISC-IV was assessed in 161 children with SeLECTS and their cognitive profiles were compared to a matched sample of healthy control children.

Results: Children with SeLECTS performed within normal range across all indices, demonstrating particular strength based on the Perceptual Reasoning Index.

Mapping the Effect of Interictal Epileptic Activity Density During Wakefulness on Brain Functioning in Focal Childhood Epilepsies With Centrotemporal Spikes.

Childhood epilepsy with centrotemporal spikes (CECTS) is the most common type of "self-limited focal epilepsies." In its typical presentation, CECTS is a condition reflecting non-lesional cortical hyperexcitability of rolandic regions. The benign evolution of this disorder is challenged by the frequent observation of associated neuropsychological deficits and behavioral impairment.

Overall cognitive profiles in patients with GLUT1 Deficiency Syndrome.

Introduction: Glucose Transporter Type I Deficiency Syndrome (GLUT1DS) classical symptoms are seizures, involuntary movements, and cognitive impairment but so far the literature has not devoted much attention to the last.

Methods: In our retrospective study involving 25 patients with established GLUT1DS diagnosis, we describe the cognitive impairment of these patients in detail and their response to the ketogenic diet in terms of cognitive improvement.

Results: We outlined a specific cognitive profile where performance skills were more affected than verbal ones, with prominent deficiencies in visuospatial and visuomotor abilities.

West syndrome in three patients with brain injury and a benign course.

Infants with West Syndrome and underlying structural pathology typically experience persistent symptomatic focal seizures and intellectual disability. We performed a retrospective case review of 84 patients with West Syndrome evaluated at one institution between 1990 and 2013. From this group we identified three patients with West syndrome and congenital hemiplegia who later developed genetic epilepsy features and had normal intellectual development.

Neurobehavioral consequences of continuous spike and waves during slow sleep (CSWS) in a pediatric population: A pattern of developmental hindrance.

Introduction: Continuous spike and waves during slow sleep (CSWS) is a typical EEG pattern defined as diffuse, bilateral and recently also unilateral or focal localization spike-wave occurring in slow sleep or non-rapid eye movement sleep. Literature results so far point out a progressive deterioration and decline of intellectual functioning in CSWS patients, i.e.

Mismatch Negativity Recording in Children With Duchenne Muscular Dystrophy: A Preliminary Study Integrating Neurophysiological and Neuropsychological Results.

Many studies on Duchenne muscular dystrophy children support the hypothesis of a specific neuropsychological phenotype affecting mostly phonological skills. This prospective study aimed to shed light on the role of phonological abilities. Fourteen Duchenne muscular dystrophy children and 7 healthy children underwent mismatch negativity.

Extrastriate visual cortex in idiopathic occipital epilepsies: The contribution of retinotopic areas to spike generation.

Objectives: To provide insight into the pathophysiology of idiopathic childhood occipital epilepsies (ICOEs), by mapping the contribution of retinotopic visual areas to the generation and sustainment of epileptic activity.

Methods: Thirteen patients affected by ICOEs (mean age = 10.9 years) underwent a video electroencephalography-functional magnetic resonance imaging (EEG-fMRI) study.

Neuropsychological profile in new-onset benign epilepsy with centrotemporal spikes (BECTS): Focusing on executive functions.

Purpose: Increased evidence of subnormal neuropsychological functioning in new-onset childhood epilepsy has been obtained, although results are still rare and controversial. With a prospective study, we aimed to define the very early neuropsychological profile of children with benign epilepsy with centrotemporal spikes (BECTS), including executive functions (EF) because of their key role in learning. Additionally, we enrolled drug-naïve children, with a NREM sleep frequency of discharges <85% and with a Performance Intelligence Quotient equal or superior to 85, in order to exclude additional effects on the neuropsychological functioning.

Comparing cortical auditory processing in children with typical and atypical benign epilepsy with centrotemporal spikes: Electrophysiologic evidence of the role of non-rapid eye movement sleep abnormalities.

Objective: The mismatch negativity (MMN) is an objective measure of central auditory discrimination. MMN alterations have been shown in children with language and/or developmental disorders. In benign focal epilepsies, neuropsychological disorders are often reported and linked to interictal epileptic discharges (IEDs) during non-rapid eye movement (NREM) sleep.

Neuropsychological approaches to epileptic encephalopathies.

The International League Against Epilepsy (ILAE) Commission report on classification and terminology indicates that "diagnosing an individual as having an encephalopathic course requires demonstration of a failure to develop as expected relative to the same-aged peers or to regress in abilities." In this chapter, basing our discussion on the theoretical framework of neuroconstructivism, on the latest results deriving from functional neuroimaging and on the concept of system epilepsy, we use continuous spike-waves during slow-wave sleep (CSWS) as an example of how non-rapid eye movement (NREM) sleep spikes interfere with the organization and consolidation of neuropsychological networks in the sensitive phase of development, affecting also interconnected systems. Indeed, recent discoveries show that the normal overnight downscaling of slow wave activity (SWA) from the first to the last hours of sleep is absent in electrical status epilepticus during sleep (ESES) patients, thus impairing the neural process and possibly the local plastic changes associated with learning and other cognitive functions.

Memory impairment and Benign Epilepsy with centrotemporal spike (BECTS): a growing suspicion.

Benign Epilepsy with centrotemporal spikes (BECTS) is considered a benign type of epilepsy; nevertheless a significant number of children present clear and heterogeneous cognitive deficits such as memory disturbances. Thus far, evidence about memory impairment has been less than conclusive. To clarify the quality of memory functioning in BECTS children, an analysis of existing findings has been conducted trying to identify the type of memory deficits and their underlying factors.

Neuropsychological development in children belonging to BECTS spectrum: long-term effect of epileptiform activity.

Benign epilepsy with centrotemporal spikes (BECTS) is an idiopathic focal epileptic syndrome in childhood. It is called "benign" because the seizure and cognitive outcomes are usually favorable, but a significant number of children with BECTS present heterogeneous cognitive deficits correlated to NREM sleep epileptiform discharges. The atypical evolutions of BECTS form a spectrum of conditions suggesting that slow sleep nocturnal interictal epileptiform discharges (IEDs) specifically determine the neuropsychological deficit.

Neuropsychological findings in Rolandic epilepsy and Landau-Kleffner syndrome.

In an attempt to correlate neuropsychological deficits and various neurophysiological aspects of focal epileptic activity in benign childhood epilepsy, we have reviewed the findings of a longitudinal group study of benign childhood epilepsy with centrotemporal spikes (BCECTS) and several case studies of continuous spike-waves during slow sleep syndrome (CSWS). We first distinguish the temporary neuropsychological impairments often observed in the natural history of BCECTS from the more long-lasting and more specific neuropsychological deficits associated with CSWS, of which the Landau-Kleffner syndrome (LKS) is the most studied clinical form. A series of metabolic findings from (18)FDG-PET studies in BCECTS and CSWS children have shown that specific cognitive impairment is related to increased glucose uptake in cortical areas restricted to the associative cortex coincident with the focus of spike-wave discharges.

The spectrum of idiopathic Rolandic epilepsy syndromes and idiopathic occipital epilepsies: from the benign to the disabling.

Benign childhood epilepsy with centrotemporal spikes (BCECTS) is an idiopathic focal epilepsy syndrome, the benign characteristics of which are debated; in fact, stable or intermittent specific neuropsychological deficits are frequent and may affect scholastic or adaptive abilities. Cognitive dysfunction may be related to a marked increment of the interictal epileptic discharges in NREM sleep: different degrees of neuropsychological deficits depend on the extent of awake and sleep activity and the predominant discharge localization. The age of onset and duration of atypical sleep EEG patterns may correlate with permanent cognitive impairments.

Neuropsychological findings: myoclonic astatic epilepsy (MAE) and Lennox-Gastaut syndrome (LGS).

Purpose: To identify a specific neuropsychological profile associated with myoclonic astatic epilepsy (MAE) and Lennox-Gastaut syndrome (LGS).

Methods: Seven patients diagnosed with MAE and four patients diagnosed with LGS were selected from patients referred to our Child Neurology Unit. The patients were assessed both clinically (awake, sleep, Holter EEG, seizures frequency, and semiology) and neuropsychologically (IQ, language, attention, visuospatial and visuomotor abilities, and behavior).
