Benign childhood epilepsy with occipital paroxysms is classified among childhood benign partial epilepsies. The absence of neurological and neuropsychological deficits has long been considered as a prerequisite for a diagnosis of benign childhood partial epilepsy. Much evidence has been reported in literature in the latest years suggesting a neuropsychological impairment in this type of epilepsy, particularly in the type with Rolandic paroxysms. The present work examines the neuropsychological profiles of a sample of subjects affected by the early-onset benign childhood occipital seizures (EBOS) described by Panayotopulos. The patient group included 22 children (14 males and 8 females; mean age 10.1+/-3.3 years) diagnosed as having EBOS. The patients were examined with a set of tests investigating neuropsychological functions: memory, attention, perceptive, motor, linguistic and academic (reading, writing, arithmetic) abilities. The same instruments have been given to a homogeneous control group as regards sex, age, level of education and socio-economic background. None of the subjects affected by EBOS showed intellectual deficit (mean IQ in Wechsler Full Scale 91.7; S.D. 8.9). Results show a widespread cognitive dysfunction in the context of a focal epileptogenic process in EBOS. In particular, children with EBOS show a significant occurrence of specific learning disabilities (SLD) and other subtle neuropsychological deficits. We found selective dysfunctions relating to perceptive-visual attentional ability (pmemory abilities (psupports the hypothesis that epilepsy itself plays a role in the development of neuropsychological impairment. Supported by other studies that have documented subtle neuropsychological deficits in benign partial epilepsy, we stress the importance of reconsidering its supposed "cognitive benignity", particularly in occipital types.

Full Text Available Despite the common assumption that genetic generalized epilepsies are characterized by a macroscopically normal brain on magnetic resonance imaging, subtle structural brain alterations have been detected by advanced neuroimaging techniques in Childhood Absence Epilepsy syndrome. We applied quantitative structural MRI analysis to a group of adolescents and adults with Juvenile Absence Epilepsy (JAE in order to investigate micro-structural brain changes using different brain measures. We examined grey matter volumes, cortical thickness, surface areas, and subcortical volumes in 24 patients with JAE compared to 24 healthy controls; whole-brain voxel-based morphometry (VBM and Freesurfer analyses were used. When compared to healthy controls, patients revealed both grey matter volume and surface area reduction in bilateral frontal regions, anterior cingulate, and right mesial-temporal lobe. Correlation analysis with disease duration showed that longer disease was correlated with reduced surface area in right pre- and post-central gyrus. A possible effect of valproate treatment on brain structures was excluded. Our results indicate that subtle structural brain changes are detectable in JAE and are mainly located in anterior nodes of regions known to be crucial for awareness, attention and memory.

To determine the origin and dynamic characteristics of the generalised hyper-synchronous spike and wave (SW) discharges in childhood absence epilepsy (CAE). We applied nonlinear methods, the error reduction ratio (ERR) causality test and cross-frequency analysis, with a nonlinear autoregressive exogenous (NARX) model, to electroencephalograms (EEGs) from CAE, selected with stringent electro-clinical criteria (17 cases, 42 absences). We analysed the pre-ictal and ictal strength of association between homologous and heterologous EEG derivations and estimated the direction of synchronisation and corresponding time lags. A frontal/fronto-central onset of the absences is detected in 13 of the 17 cases with the highest ictal strength of association between homologous frontal followed by centro-temporal and fronto-central areas. Delays consistently in excess of 4 ms occur at the very onset between these regions, swiftly followed by the emergence of "isochronous" (0-2 ms) synchronisation but dynamic time lag changes occur during SW discharges. In absences an initial cortico-cortical spread leads to dynamic lag changes to include periods of isochronous interhemispheric synchronisation, which we hypothesize is mediated by the thalamus. Absences from CAE show ictal epileptic network dynamics remarkably similar to those observed in WAG/Rij rats which guided the formulation of the cortical focus theory.

OBJECTIVE: To assess the influence of parental rheumatoid arthritis (RA) on risk of epilepsy. METHODS: We performed a nationwide cohort study including all singletons born in Denmark from 1977 to 2008 (n = 1,917,723) through individual linkage to nationwide Danish registries. The children were...... followed for an average of 16 years. Main outcome measures were adjusted hazard ratios (HRs) for epilepsy with onset in early childhood (29 days-4 years), late childhood (5-15 years), adolescence/adulthood (≥15 years), and at any age until the end of follow-up (December 31, 2010). RESULTS: Compared...... to unexposed children, children exposed to maternal RA had an increased risk of early and late childhood epilepsy (adjusted HRs 1.34 [95% confidence interval (CI) 1.13-1.60] and 1.26 [95% CI 1.13-1.41]), while children exposed to maternal RA had no increased risk of epilepsy in adolescence/adulthood (HR 1...

To investigate whether patients with typical absence seizures (TAS) starting in the first 3 years of life, conformed to Panayiotopoulos's definition of childhood absence epilepsy (CAE), show different electroclinical course than those not fulfilling CAE criteria. In this multicenter retrospective study, we choose a fixed duration follow-up of 36 months to examine the electroclinical course of epilepsy in all children with TAS starting before 3 years of age. The probands who fulfilled Panayiotopoulos's criteria for CAE were classified as having pure early onset absence epilepsy (P-EOAE), whereas those who did not as nonpure EOAE (NP-EOAE). In addition, these two groups of patients were further stratified according to the number of antiepileptic drugs taken to obtain initial seizure control (mono-, bi-, and tritherapy). Patients with P-EOAE (n = 111) showed earlier initial seizure control (p = 0.030) and better seizure-free survival curve (p = 0.004) than those with NP-EOAE (n = 77). No mutation in SLC2A1 gene or abnormal neuroimaging was observed in P-EOAE. Among patients with NP-EOAE, those receiving tritherapy showed increased risk of structural brain abnormalities (p = 0.001) or SLC2A1 mutations (p = 0.001) but fewer myoclonic features (p = 0.031) and worse seizure-free survival curve (p = 0.047) than those treated with mono- and bitherapy. Children with NP-EOAE had 2.134 the odds of having relapse during the follow-up compare to those with P-EOAE. Children with early onset TAS who did meet Panayiotopoulos's criteria showed a favorable course of epilepsy, whereas patients not fulfilling Panayiotopoulos's criteria showed increased risk of relapse at long-term follow-up.

Altered sensory sensitivity is generally linked to seizure-susceptibility in childhood epilepsy but may also be associated to the highly prevalent problems in behavioral adaptation. This association is further suggested by the frequent overlap of childhood epilepsy with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), conditions in which altered behavioral responses to sensory stimuli have been firmly established. A continuum of sensory processing defects due to imbalanced neuronal inhibition and excitation across these disorders has been hypothesizedthat may lead to common symptoms of inadequate modulation of behavioral responses to sensory stimuli. Here, we investigated the prevalence of sensory modulation disorders among children with epilepsy and their relation with symptomatology of neurodevelopmental disorders. We used the Sensory Profile questionnaire to assess behavioral responses to sensory stimuli and categorize sensory modulation disorders in children with active epilepsy (aged 4-17 years). We related these outcomes to epilepsy characteristics and tested their association with comorbid symptoms of ASD (Social Responsiveness Scale) and ADHD (Strengths and Difficulties Questionnaire). Sensory modulation disorders were reported in 49 % of the 158 children. Children with epilepsy reported increased behavioral responses associated with sensory "sensitivity," "sensory avoidance," and "poor registration" but not "sensory seeking." Comorbidity of ASD and ADHD was associated with more severe sensory modulation problems, although 27 % of typically developing children with epilepsy also reported a sensory modulation disorder. Sensory modulation disorders are an under-recognized problem in children with epilepsy. The extent of the modulation difficulties indicates a substantial burden on daily functioning and may explain an important part of the behavioral distress associated with childhood epilepsy.

2016-09-01

Findings of material-specific influences on memory performance in pediatric epilepsy are inconsistent and merit further investigation. This study compared 90 children (aged 6years to 16years) with childhood absence epilepsy (CAE), frontal lobe epilepsy (FLE), and temporal lobe epilepsy (TLE) to determine whether they displayed distinct list-learning and verbal memory profiles on the California Verbal Learning Test - Children's Version (CVLT-C). Group comparison identified greater risk of memory impairment in children with TLE and FLE syndromes but not for those with CAE. While children with TLE performed worst overall on Short Delay Free Recall, groups with TLE and FLE performed similarly on Long Delay Free Recall. Contrast indices were then employed to explore these differences. Children with TLE demonstrated a significantly greater retroactive interference (RI) effect compared with groups with FLE and CAE. Conversely, children with FLE demonstrated a significantly worse learning efficiency index (LEI), which compares verbal memory following repetition with initial recall of the same list, than both children with TLE and CAE. These findings indicated shallow encoding related to attentional control for children with FLE and retrieval deficits in children with TLE. Finally, our combined sample showed significantly higher rates of extreme contrast indices (i.e., 1.5 SD difference) compared with the CVLT-C standardization sample. These results underscore the high prevalence of memory dysfunction in pediatric epilepsy and offer support for distinct patterns of verbal memory performance based on childhood epilepsy syndrome.

2015-10-01

Full Text Available Background Epilepsy affects 1% of children worldwide. The highest incidence is in the first year of life, and perinatal factors, such as hypoxic-ischemic injury, infection, and cortical malformation may play etiologic roles. Breast milk contains optimal nutrients for human brain in early life. Breastfeeding has been associated with lower risk of infections, better cognitive and psychomotor development. However, the role of breastfeeding in preventing childhood epilepsy remains unclear. Objective To evaluate an association between exclusive breastfeeding and childhood epilepsy. Methods A case-control study conducted from 1 May to 3 July 2013 involving children with epilepsy aged 6 months to 18 years who were attending pediatric outpatient clinic of Dr. Sardjito Hospital, Yogyakarta. Neurologically normal children, individually matched by age and sex, visiting the same clinic were considered as controls. Exclusion criteria were children with structural brain abnormality, history of epilepsy in family, and who had history of neonatal seizure, intracranial infection, febrile seizure, and head trauma before onset of epilepsy. History of breastfeeding was obtained by interviewing the parents. The difference of exclusively breastfeeding proportion between cases and controls was analyzed by McNemar test. Results The total number of participants was 68 cases and controls each. Subjects with epilepsy had lower proportion of exclusively breastfed (48.5% compared with controls (54.4%, but the difference was not statistically significant (P=0.541. Exclusively breastfeeding showed no statistical significance in decreasing risk of epilepsy (OR=0.71; 95%CI 0.32 to 1.61. Conclusions Exclusive breastfeeding for 4-6 months has no effect against childhood epilepsy.

SUDEP and other causes of mortality in childhood-onset epilepsy.

There are few prospective studies on the causes of mortality in well-characterized cohorts with epilepsy and even fewer that have autopsy data that allow for reliable determination of SUDEP. We report causes of mortality and mortality rates in the Finnish cohort with childhood-onset epilepsy. A population-based cohort of 245 children with epilepsy in 1964 has been prospectively followed for almost 40 years. Seizure outcomes and mortality were assessed. Autopsy data were available in 70% of the cases. Sudden unexpected death in epilepsy (SUDEP) rates were assessed, and SUDEP was confirmed by autopsy. During the follow-up, 60 subjects died. The major risk factor for mortality was lack of terminal remission (p epilepsy-related including SUDEP in 23/60 (38%) using the Nashef criteria, status epilepticus in 4/60 (7%), and accidental drowning in 6/60 (10%). The nonepilepsy-related deaths occurred primarily in the remote symptomatic group and were often related to the underlying disorder or to medical comorbidities that developed after the onset of the epilepsy. Risk factors for SUDEP on multivariable analysis included lack of 5-year terminal remission and not having a localization-related epilepsy. In cryptogenic/idiopathic cases, SUDEP did not occur in childhood but begins only in adolescence. Childhood-onset epilepsy is associated with a substantial risk of epilepsy-related mortality, primarily SUDEP. In otherwise neurologically normal individuals, the increased SUDEP risk begins in adolescence. The higher mortality rates reported in this cohort are related to duration of follow-up as most of the mortality occurs many years after the onset of the epilepsy. Copyright © 2013 Elsevier Inc.

This study evaluated the effect of topiramate (TPM) on the quality of life (QOL) in childhood epilepsy, using the Korean quality of life in childhood epilepsy (K-QOLCE) questionnaire. An open label, prospective, observational study of the families of 664 children with epilepsy from 41 centers was conducted. The parents completed the K-QOLCE at the baseline visit and again 6months after starting TPM treatment. The parents reported the seizure frequency at both assessment dates. Statistically significant improvements in all K-QOLCE domains except social functioning were found at 6months after starting TPM treatment from the baseline-scores (P<0.05). However, improved QOL scores were not dependent on the reduction in seizure frequency. TPM significantly improved QOL in children with epilepsy, suggesting its potential clinical benefits.

Epilepsy is one of the most common neurological disorders prevalent in childhood period. There is scarcity of epidemiological data, required to plan services in resource constrained developing nations. To study the prevalence and treatment gap in childhood epilepsy in north Indian city, in the age group of 1-18 years. A two stage stratified cluster sampling; probability proportionate to size (PPS) was employed. A ten question screening questionnaire was employed to identify the presence of epilepsy. Definitions provided by International League against Epilepsy (ILAE) were used to classify screen positive subjects as epilepsy and to calculate the treatment gap. The prevalence rate for epilepsy was 6.24/1000 population. Febrile seizures and neurocysticercosis were most common causes of symptomatic seizures in childhood. This study of epidemiology of epilepsy provides valuable aid in optimizing effective community approach, thereby improving outcomes of childhood epilepsy.

Idiopathic photosensitive occipital lobe epilepsy (IPOE) is an idiopathic localization-related epilepsy characterized by age-related onset, specific mode of precipitation, occipital photic-induced seizures--frequently consisting of visual symptoms--and good prognosis. This uncommon epilepsy, which usually starts in childhood or adolescence, has rarely been observed in families in which idiopathic generalized epilepsy also affects other members. We describe a nuclear family in which the proband showed electro-clinical features of idiopathic photosensitive occipital lobe epilepsy in childhood, which subsequently evolved into absences and a single generalized tonico-clonic seizure in early adolescence. His mother had features suggestive of juvenile myoclonic epilepsy. This case illustrates a continuum between focal and generalized entities in the spectrum of the so-called idiopathic (genetically determined) epileptic syndromes.

2009-01-01

The International League Against Epilepsy (ILAE) Subcommittee for Pediatric Neuroimaging examined the usefulness of, and indications for, neuroimaging in the evaluation of children with newly diagnosed epilepsy. The retrospective and prospective published series with n ≥ 30 utilizing computed tomography (CT) and magnetic resonance imaging (MRI) (1.5 T) that evaluated children with new-onset seizure(s) were reviewed. Nearly 50% of individual imaging studies in children with localization-related new-onset seizure(s) were reported to be abnormal; 15-20% of imaging studies provided useful information on etiology or and seizure focus, and 2-4% provided information that potentially altered immediate medical management. A significant imaging abnormality in the absence of a history of a localization-related seizure, abnormal neurologic examination, or focal electro-encephalography (EEG) is rare. Imaging studies in childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, and benign childhood epilepsy with centro-temporal spikes (BECTS) do not identify significant structural abnormalities. Imaging provides important contributions to establishing etiology, providing prognostic information, and directing treatment in children with recently diagnosed epilepsy. Imaging is recommended when localization-related epilepsy is known or suspected, when the epilepsy classification is in doubt, or when an epilepsy syndrome with remote symptomatic cause is suspected. When available, MRI is preferred to CT because of its superior resolution, versatility, and lack of radiation. (authors)

2017-09-01

Childhood maltreatment has been shown to be a risk factor for the development of psychiatric disorders. Although the prevalence of psychiatric disorders is high in epilepsy patients, it is unknown if childhood maltreatment experiences are elevated compared to the normal population and if early maltreatment is a risk factor for current psychiatric comorbidities in epilepsy patients. This is the main purpose of this study. Structured interviews were used to assess current Axis I diagnoses in 120 epilepsy patients from a tertiary Epilepsy Center (34 TLE patients, 86 non-TLE patients). Childhood maltreatment in the family and peer victimization were assessed with validated questionnaires. Patients' maltreatment scores were compared with those of a representative matched control group. Logistic regression analysis was conducted to assess the potential impact of childhood maltreatment on current psychiatric comorbidity in epilepsy patients. Compared to a matched control group, epilepsy patients had higher emotional and sexual maltreatment scores. Patients with a current psychiatric diagnosis reported more family and peer maltreatment than patients without a psychiatric disorder. Family maltreatment scores predicted the likelihood of a current psychiatric disorder. TLE patients did not differ from non-TLE patients according to maltreatment experiences and rates of current psychiatric disorders. Our findings suggest that in epilepsy patients emotional and sexual childhood maltreatment is experienced more often than in the normal population and that early maltreatment is a general risk factor for psychiatric comorbidities in this group.

Improving health-related quality of life (HRQOL), rather than just reducing seizures, should be the principal goal in comprehensive management of childhood epilepsy. There is a lack of population-based data on predictors of HRQOL in childhood epilepsy. The Children with Epilepsy in Sussex Schools (CHESS) study is a prospective, population-based study involving school-aged children (5-15 years) with active epilepsy (on one or more AED and/or had a seizure in the last year) in a defined geographical area in the UK. Eighty-five of 115 (74% of eligible population) children underwent comprehensive psychological assessment including measures of cognition, behaviour, and motor functioning. Parents of the children completed the Quality of Life in Childhood Epilepsy (QOLCE).Clinical data on eligible children was extracted using a standardised pro forma. Linear regression analysis was undertaken to identify factors significantly associated with total Quality of Life in this population. Factors independently significantly associated (p QOLCE scores were seizures before 24 months, cognitive impairment (IQ QOLCE when children with IQ < 50 were excluded from analysis. The majority of factors associated with parent reported HRQOL in active childhood epilepsy are related to neurobehavioural and/or psychosocial aspects of the condition.

Cases were chosen from the Central League against Epilepsy's clinic in Bogotá, Colombia. Controls were selected from a private school and matched with cases by age, school year, and sex. Medical history, seizure frequency, antiepileptic treatment, and academic performance were assessed. Academic abilities were tested with Batería de Aptitudes Diferenciales y Generales (BADyG) (a Spanish-language test of differential and general aptitudes). Data were analysed using Student t-test. The sample consisted of 19 cases and 19 controls aged between 7 and 16. In 15 patients, seizures were controlled; all patients had received antiepileptic medication at some point and 78.9% were actively being treated. Although cases had higher rates of academic failure, a greater incidence of grade retention, and more therapeutic interventions than controls, these differences were not significant. Similarly, there were no significant differences on the BADyG test, except for the immediate memory subcategory on which cases scored higher than controls (P=.0006). Children treated pharmacologically for absence epilepsy, whose seizures are controlled, have normal academic abilities and skills for their age. Copyright © 2013 Sociedad Española de Neurología.

Gastaut type idiopathic childhood occipital epilepsy is an uncommon epileptic syndrome characterised by frequent seizures, most commonly presenting as elementary visual hallucinations or blindness. Other occipital (non-visual) symptoms may also occur. Interictal EEG typically shows occipital paroxysms, often with fixation-off sensitivity. Ictal EEG is usually characterised by interruption by paroxysms and sudden appearance of low-voltage, occipital, fast rhythm and/or spikes. Despite well described clinical and EEG patterns, to our knowledge, there are very few reports in the literature with video-EEG recording of either seizure semiology or fixation-off phenomena. We present a video-EEG recording of a 12-year-old girl with Gastaut type epilepsy, illustrating the interictal and ictal aspects of this syndrome. Our aim was to demonstrate the clinical and neurophysiological pattern of a typical seizure of Gastaut type epilepsy, as well as the fixation-off phenomena, in order to further clarify the typical presentation of this syndrome.

We aimed to compare long-term social outcomes in young adults with childhood-onset epilepsy (cases) with neurologically normal sibling controls. Long-term social outcomes were assessed at the 15-year follow-up of the Connecticut Study of Epilepsy, a community-based prospective cohort study of children with newly diagnosed epilepsy. Young adults with childhood-onset epilepsy with complicated (abnormal neurologic exam findings, abnormal brain imaging with lesion referable to epilepsy, intellectual disability (ID; IQ < 60) or informative history of neurologic insults to which the occurrence of epilepsy might be attributed), and uncomplicated epilepsy presentations were compared to healthy sibling controls. Age, gender, and matched-pair adjusted generalized linear models stratified by complicated epilepsy and 5-year seizure-free status estimated adjusted odds ratios (aORs) and 95% confidence intervals [CIs] for each outcome. The 15-year follow-up included 361 individuals with epilepsy (59% of initial cases; N = 291 uncomplicated and N = 70 complicated epilepsy; mean age 22 years [standard deviation, SD 3.5]; mean epilepsy onset 6.2 years [SD 3.9]) and 173 controls. Social outcomes for cases with uncomplicated epilepsy with ≥5 years terminal remission were comparable to controls; cases with uncomplicated epilepsy <5 years seizure-free were more likely to be less productive (school/employment < 20 h/week) (aOR 3.63, 95% CI 1.83-7.20) and not to have a driver's license (aOR 6.25, 95% CI 2.85-13.72). Complicated cases with epilepsy <5 years seizure-free had worse outcomes across multiple domains; including not graduating high school (aOR 24.97, 95% CI 7.49-83.30), being un- or underemployed (<20 h/week) (aOR 11.06, 95% CI 4.44-27.57), being less productively engaged (aOR 15.71, 95% CI 6.88-35.88), and not living independently (aOR 10.24, 95% CI 3.98-26.36). Complicated cases without ID (N = 36) had worse outcomes with respect to productive engagement (aOR 6.02; 95% CI 2

Objectives To describe the prevalence of epilepsy after 6 months-of-age in children with perinatal stroke and examine whether perinatal data predict epilepsy onset and resolution. Study design A retrospective review of 64 children with perinatal stroke. In children with at least 6 months of follow-up data, Kaplan-Meier curves, univariate log-rank tests, and Cox proportional hazards models were used to examine predictors of time to development of seizures, and time to resolution of seizures in children with epilepsy. The association of risk factors with the presence of epilepsy at any time after 6 months-of-age was examined using Fisher’s exact test. Results Forty-one of the 61 children with at least 6 months of follow-up data (67%) had epilepsy between 6 months-of-age and last follow-up, but in 13 of 41 seizures eventually resolved and anticonvulsants were discontinued. Infarct on prenatal ultrasound (p=0.0065) and family history of epilepsy (p=0.0093) were significantly associated with time to development of seizures after 6 months-of-age in the univariate analysis. No assessed variables were associated with time to resolution of epilepsy or with the presence of epilepsy after 6 months-of-age. Conclusions Childhood epilepsy is frequent after perinatal stroke. Evidence of infarction on prenatal ultrasound and a family history of epilepsy predict earlier onset of active seizures. PMID:17889079

Impact of Childhood Epilepsy on the Family

Full Text Available Whole family is affected when an illness appears in the family or when there is an uncertainty regarding the health of a member. Symptoms, therapy, course of the disorder, constraint of the daily activities and long term effects of childhood chronic diseases deeply impact health and structure of the families. Diagnosis of a chronic disease in children presents as a significant psychological and psychosocial risk factor to the parents and other family members. Despite these known facts, psychosocial problems of parents of epileptic children are often ignored and not even questioned. These parents frequently have to leave their jobs or ask for their elderly relatives to look after their children. This situation could lead to major financial and social problems, weakening in intrafamilial communication and disruption in family harmony. Childhood epilepsy brings a great strain on family’s resources as other chronic diseases do and alter the life of significant others. According to biopsychosocial model, schemas in family relations influence the psychological process of the family members while the biopsychosocial process of the sick individual affect the functionality of the family. In other words, epilepsy affects not only the sick individual but also the family union. The family has to face many problems after definite diagnosis of epilepsy. Majority of the studies conducted on this issue mainly focused on the quality of life and family relations of the sick child, whereas only a few studies searched for possible burden and resulting problems of family members caused by epilepsy. Physicians in charge should not only focus on physical and mental health of the sick children but also on the problems of other members in the family bearing in mind psychosocial influences of the disorder on them. Additionally, preventive methods should be administered to protect the family from developing mental health problems. A multidiscipline training program

Even if considered benign, absence epilepsy may alter memory and attention, sometimes subtly. Very little is known on behavior and cognitive functions in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model of absence epilepsy. We focused on different memory systems and sustained visual attention, using Non Epileptic Controls (NECs) and Wistars as controls. A battery of cognitive/behavioral tests was used. The functionality of reference, working, and procedural memory was assessed in the Morris water maze (MWM), 8-arm radial maze, T-maze and/or double-H maze. Sustained visual attention was evaluated in the 5-choice serial reaction time task. In the MWM, GAERS showed delayed learning and less efficient working memory. In the 8-arm radial maze and T-maze tests, working memory performance was normal in GAERS, although most GAERS preferred an egocentric strategy (based on proprioceptive/kinesthetic information) to solve the task, but could efficiently shift to an allocentric strategy (based on spatial cues) after protocol alteration. Procedural memory and visual attention were mostly unimpaired. Absence epilepsy has been associated with some learning problems in children. In GAERS, the differences in water maze performance (slower learning of the reference memory task and weak impairment of working memory) and in radial arm maze strategies suggest that cognitive alterations may be subtle, task-specific, and that normal performance can be a matter of strategy adaptation. Altogether, these results strengthen the "face validity" of the GAERS model: in humans with absence epilepsy, cognitive alterations are not easily detectable, which is compatible with subtle deficits.

2011-06-01

A great number of clinical observations show a relationship between epilepsy and depression. Idiopathic generalized epilepsy, including absence epilepsy, has a genetic basis. The review provides evidence that WAG/Rij rats can be regarded as a valid genetic animal model of absence epilepsy with comorbidity of depression. WAG/Rij rats, originally developed as an animal model of human absence epilepsy, share many EEG and behavioral characteristics resembling absence epilepsy in humans, including the similarity of action of various antiepileptic drugs. Behavioral studies indicate that WAG/Rij rats exhibit depression-like symptoms: decreased investigative activity in the open field test, increased immobility in the forced swimming test, and decreased sucrose consumption and preference (anhedonia). In addition, WAG/Rij rats adopt passive strategies in stressful situations, express some cognitive disturbances (reduced long-term memory), helplessness, and submissiveness, inability to make choice and overcome obstacles, which are typical for depressed patients. Elevated anxiety is not a characteristic (specific) feature of WAG/Rij rats; it is a characteristic for only a sub-strain of WAG/Rij rats susceptible to audiogenic seizures. Interestingly, WAG/Rij rats display a hyper-response to amphetamine similar to anhedonic depressed patients. WAG/Rij rats are sensitive only to chronic, but not acute, antidepressant treatments, suggesting that WAG/Rij rats fulfill a criterion of predictive validity for a putative animal model of depression. However, more and different antidepressant drugs still await evaluation. Depression-like behavioral symptoms in WAG/Rij rats are evident at baseline conditions, not exclusively after stress. Experiments with foot-shock stress do not point towards higher stress sensitivity at both behavioral and hormonal levels. However, freezing behavior (coping deficits) and blunted response of 5HT in the frontal cortex to uncontrollable sound stress

Epilepsy, febrile seizures, and attention-deficit/hyperactivity disorder (ADHD) are disorders of the central nervous system and share common risk factors. Our goal was to examine the association in a nationwide cohort study with prospective follow-up and adjustment for selected confounders. We hypothesized that epilepsy and febrile seizures were associated with subsequent ADHD. A population-based cohort of all children born in Denmark from 1990 through 2007 was followed up until 2012. Incidence rate ratios (IRRs) and 95% confidence intervals (95% CIs) for ADHD were estimated by using Cox regression analysis, comparing children with epilepsy and febrile seizure with those without these disorders, adjusted for socioeconomic and perinatal risk factors, as well as family history of neurologic and psychiatric disorders. A total of 906 379 individuals were followed up for 22 years (∼10 million person-years of observation); 21 079 individuals developed ADHD. Children with epilepsy had a fully adjusted IRR of ADHD of 2.72 (95% CI, 2.53-2.91) compared with children without epilepsy. Similarly, in children with febrile seizure, the fully adjusted IRR of ADHD was 1.28 (95% CI, 1.20-1.35). In individuals with both epilepsy and febrile seizure, the fully adjusted IRR of ADHD was 3.22 (95% CI, 2.72-3.83). Our findings indicate a strong association between epilepsy in childhood and, to a lesser extent, febrile seizure and subsequent development of ADHD, even after adjusting for socioeconomic and perinatal risk factors, and family history of epilepsy, febrile seizures, or psychiatric disorders.

Kavanaugh, Brian C; Scarborough, Vanessa Ramos; Salorio, Cynthia F

2015-01-01

The present study examined clinical and demographic risk factors associated with parent-rated emotional-behavioral and executive functioning in children and adolescents with epilepsy. The medical records of 152 children and adolescents with epilepsy referred for neuropsychological evaluation were reviewed. Results indicated that the sample displayed significantly elevated symptoms across the emotional-behavioral and executive domains assessed. Executive functioning and behavioral symptoms had the highest rates of clinically elevated scores, with lowest rates of elevated scores in internalizing and externalizing emotional problems. Only 34% of those participants with clinically significant emotional-behavioral or executive functioning difficulties had a history of psychological or counseling services, highlighting the underserved mental health needs of this population. In regard to clinical factors, the majority of seizure-related variables were not associated with emotional-behavioral or executive functioning. However, the frequency of seizures (i.e., seizure status) was associated with behavioral regulation aspects of executive functioning, and the age at evaluation was associated with externalizing problems and behavioral symptoms. Family psychiatric history (with the exception of ADHD) was associated with all domains of executive and emotional-behavioral functioning. In summary, emotional-behavioral and executive functioning difficulties frequently co-occur with seizures in childhood epilepsy, with both seizure-related and demographic factors contributing to the presentation of such neurobehavioral comorbidities. The present findings provide treatment providers of childhood epilepsy with important information to assist in better identifying children and adolescents who may be at risk for neurobehavioral comorbidities and may benefit from intervention.

To estimate long-term socioeconomic consequences and health care costs of epilepsy with onset in childhood and adolescence. A historical prospective cohort study of Danish individuals with epilepsy, age up to 20 years at time of diagnosis between January 1981 and December 2012. Information about marital status, parenthood, educational level, employment status, income, use of the health care system, and cost of medicine was obtained from nationwide administrative and health registers. We identified 12,756 and 28,319 people with diagnosed with epilepsy, ages 0-5 and 6-20 years at onset, respectively. Using follow-up data for a maximum of 30 years, 1,394 of those ages 0-5 years at onset were compared with 2,897 controls persons without epilepsy, and 10,195 of those ages 6-20 years at onset were compared with 20,678 controls without epilepsy. Compared with people without the epilepsy, those with epilepsy tended to have a lower level of education, to be less likely to be married, to be more likely to live alone, and to have higher divorce and unemployment rates, lower employment rates, and people with epilepsy were more likely to receive disability pension and social security. Income was lower from employment, which in part was compensated by social security, sick pay, disability pension and unemployment benefit, sick pay (public-funded), disability pension, and other public transfers. Predicted health care costs 30 years after epilepsy onset were significantly higher among persons with epilepsy onset at 0-5 and 6-20 years, including costs for outpatient and inpatient services (hospital services), emergency room use, primary health care sector (general practice), and use of medication. The long-term negative effects on all aspects of health care and social domains, including marital status, parental socioeconomic status, educational level, employment status, and use of welfare benefits compared with controls without epilepsy calls for increased awareness on

To study the relationship between seizure-related factors, non-verbal intelligence, and socio-economic status (SES) in a population-based sample of children with epilepsy. The latest ILAE International classifications of epileptic seizures and syndromes were used to classify seizure types and epileptic syndromes in all 6-12 year old children (N=198) with epilepsy in Hordaland County, Norway. The children had neuropediatric and EEG examinations. Of the 198 patients, demographic characteristics were collected on 183 who participated in psychological studies including Raven matrices. 126 healthy controls underwent the same testing. Severe non-verbal problems (SNVP) were defined as a Raven score at or Raven percentile group, whereas controls were highly over-represented in the higher percentile groups. SNVP were present in 43% of children with epilepsy and 3% of controls. These problems were especially common in children with remote symptomatic epilepsy aetiology, undetermined epilepsy syndromes, myoclonic seizures, early seizure debut, high seizure frequency and in children with polytherapy. Seizure-related characteristics that were not usually associated with SNVP were idiopathic epilepsies, localization related (LR) cryptogenic epilepsies, absence and simple partial seizures, and a late debut of epilepsy. Adjusting for socio-economic status factors did not significantly change results. In childhood epilepsy various seizure-related factors, but not SES factors, were associated with the presence or absence of SNVP. Such deficits may be especially common in children with remote symptomatic epilepsy aetiology and in complex and therapy resistant epilepsies. Low frequencies of SNVP may be found in children with idiopathic and LR cryptogenic epilepsy syndromes, simple partial or absence seizures and a late epilepsy debut. Our study contributes to an overall picture of cognitive function and its relation to central seizure characteristics in a childhood epilepsy population

We investigated the relationship between abnormal electroencephalogram (EEG) findings such as localized EEG paroxysmal abnormality (PA) and the perception of stigma to determine EEG factors associated with perceived stigma in childhood epilepsy. Participants comprised 40 patients (21 boys, 19 girls; mean age, 14.6 years) with epilepsy at enrollment. The criteria for inclusion were as follows: 1) age of 12-18 years, inclusive; 2) ≥6 months after epilepsy onset; 3) the ability to read and speak Japanese; and 4) the presence of EEG PA. Fifteen healthy seizure-free children were included as a control group. Participants were asked to rate how often they felt or acted in the ways described in the items of the Child Stigma Scale using a 5-point scale. Electroencephalogram paroxysms were classified based on the presence of spikes, sharp waves, or spike-wave complexes, whether focal or generalized. Participants showed significantly higher stigma scores than healthy subjects (pstigma. The average total scores of patients presenting with EEG PA at generalized, frontal, RD, midtemporal, and occipital regions were 2.3, 4.0, 2.4, 3.2, and 2.2, respectively. The scores of all questions were higher in the frontal group than those in other regions (pstigma than children presenting with nonfrontal EEG PA (pstigma. Further studies are needed to confirm whether frontal EEG PA may function as a mediator of emotional responses such as perceived stigma in childhood epilepsy. Copyright © 2015 Elsevier Inc.

Full Text Available Objective: To optimize the use of phenobarbital and/or phenytoin as frontline drugs for treatment of childhood epilepsy. Design: Before-and -after study. Setting: Epilepsy clinic at paediatric OPD, Sassoon General Hospital, Pune. Materials and Methods: Epilepsy is a condition in which seizures are triggered recurrently from within the brain. For epidemiological classification purpose epilepsy is considered to be present when two or more unprovoked seizures occur at an interval greater than twenty four hours apart. Seizures were classified as generalized and partial seizures, with underlying etiology investigated with EEG, CT scan in majority of the patients. Follow - up rate, seizure - control and antiepileptic drugs used among 151 children enrolled as on 31 March 2005 were compared with 106 children with new onset epilepsy enrolled as on February 2006. Eight children with breakthrough convulsion after a seizure free period of five to eighteen months were followed up after injection vitamin D. Nineteen children with poor control of seizures receiving polytherapy with newer antiepileptic drugs were assessed with frontline antiepileptic medication of phenobarbital and/or phenytoin. Serum calcium, phosphorus, alkaline phosphatase were done in seventy two consecutive children with seizure disorder. Results: During post protocol period good seizure control was achieved in 84.8% as against 80.7% and use of phenobarbital and/or phenytoin increased to 65.11% from 22.87%. Of the 8 cases with breakthrough seizures seven remained seizure free after vitamin D administration and with no dose enhancement of AED medications of the nineteen. Children receiving polytherapy thirteen children could be successfully switched to phenobarbital and/or phenytoin. Forty four (61% children had hypocalcemia (less than 9 mg%, fifty seven (79% children had raised alkaline phosphatase levels (more than 270 IU.

BACKGROUND: Adults with childhood-onset epilepsy experience poorer adult social outcomes than their peers. The relative roles of seizures over time versus learning and psychiatric problems are unclear. METHODS: We examined independent influences of psychiatric and learning disorders and of seizure course in 241 young adults (22–35 years old) with uncomplicated epilepsy in a longitudinal community-based cohort study. Social outcomes were ascertained throughout the study. A history of psychiatric and learning problems was ascertained ∼9 years after study entry. Seizure course was: “Excellent,” no seizures after the first year, in complete remission at last contact (N = 95, 39%); “Good,” seizures occurred 1 to 5 years after diagnosis, in complete remission at last contact (N = 56, 23%); “Fluctuating,” more complicated trajectories, but never pharmacoresistant (N = 70, 29%); “Pharmacoresistant,” long-term pharmacoresistant (N = 20, 8%). Multiple logistic regression was used to identify contributors to each social outcome. RESULTS: Better seizure course predicted college completion, being either employed or pursuing a degree, and driving, but was not substantially associated with other social outcomes. Poorer seizure course was associated with a greater likelihood of having offspring, particularly in women without partners. Learning problems, psychiatric disorders, or both negatively influenced all but 2 of the social outcomes. CONCLUSIONS: In young adults with uncomplicated epilepsy, the course of seizures contributed primarily to education, employment, and driving. A history of learning problems and psychiatric disorders adversely influenced most adult outcomes. These findings identify potential reasons for vocational and social difficulties encountered by young adults with childhood epilepsy and areas to target for counseling and transition planning.

Childhood epilepsy is a chronic neurological disorder associated with profound psychosocial limitations epileptic children's routine. Lack of information and inappropriate beliefs are still the factors that most contribute to the stigma and discrimination. This study aimed at characterizing teacher's beliefs and attitudes at regular and special schools in two cities of southeastern Brazil where students with epilepsy studied. Fifty-six teachers of public regular schools and specialized educational institutions for children with disabilities from two cities of Southeast Brazil who had epileptic children in their classroom completed the Brazilian version of The Epilepsy Beliefs and Attitudes Scale: Adult Version and answered a data sheet about sociodemographic characteristics. The results showed that no significant differences (P ≤ 0.05) have been found between the beliefs and attitudes of teachers in mainstream and special schools but both schoolteachers had more inappropriate beliefs and attitudes than appropriate ones against childhood epilepsy. These findings raise an important issue, providing us with the knowledge that epilepsy is still a condition which is surrounded by wrong beliefs. Also, educational programs could help reduce the gaps in knowledge about how such disease has been perceived worldwide.

The aim of this study was to adapt the Australian Quality of Life in Childhood Epilepsy Questionnaire (QOLCE) and determine its psychometric properties in a North American population. Participants were North American families with children diagnosed with epilepsy. Parents were asked to complete the American QOLCE (USQOLCE) and the Child Health Questionnaire (CHQ). Seventy-one families completed the USQOLCE. The internal consistency reliability of the subscales was good. USQOLCE subscales correlated highly with theoretically similar subscales contained in the CHQ. Theoretically dissimilar subscales on the two instruments did not correlate as well. USQOLCE correlated significantly with a parental rating of seizure severity and an independent measure of degree of postoperative seizure control. This study demonstrated that the USQOLCE is suitable for a North American population with evidence of its reliability and validity including its sensitivity to seizure burden.

The neurochemical basis of absence seizures is uncertain. A previous PET study has provided evidence for release of endogenous opioids from cerebral cortex at the time of absence seizures, but it is has not yet been established whether there is an abnormality of opiate receptor numbers interictally. In the present study, the non-specific opiate receptor ligand, [11C]diprenorphine, was used to measure cerebral opiate receptors interictally in patients with childhood and juvenile absence epilepsy. Eight patients and eight normal controls had a single scan after a high specific activity injection of [11C]diprenorphine. The cerebral volume of distribution (Vd) of [11C]diprenorphine relative to plasma was calculated on a pixel-by-pixel basis. There were no significant differences in [11C]diprenorphine Vd between patients and control subjects in either cortex or thalamus, structures thought to be involved in the pathogenesis of absence seizures. The results suggest that there is no overall abnormality of opioid receptors in patients with childhood and juvenile absence epilepsy. Studies with specific ligands may provide information about the different receptor subtypes.

To investigate what proportion of a regional cohort of cooled infants with neonatal encephalopathy develop epilepsy (determined by the International League Against Epilepsy [ILAE] definition and the number of antiepileptic drugs [AEDs]) up to 8 years of age. From 2006-2013, 151 infants with perinatal asphyxia underwent 72 h cooling. Clinical and amplitude-integrated electroencepalography (aEEG) with single-channel EEG-verified neonatal seizures were treated with AEDs. Brain magnetic resonance imaging (MRI) was assessed using a 0-11 severity score. Postneonatal seizures, epilepsy rates, and AED treatments were documented. One hundred thirty-four survivors were assessed at 18-24 months; adverse outcome was defined as death or Bayley III composite Cognition/Language or Motor scores <85 and/or severe cerebral palsy or severely reduced vision/hearing. Epilepsy rates in 103 children age 4-8 years were also documented. aEEG confirmed seizures occurred precooling in 77 (57%) 151 of neonates; 48% had seizures during and/or after cooling and received AEDs. Only one infant was discharged on AEDs. At 18-24 months, one third of infants had an adverse outcome including 11% mortality. At 2 years, 8 (6%) infants had an epilepsy diagnosis (ILAE definition), of whom 3 (2%) received AEDs. Of the 103 4- to 8-year-olds, 14 (13%) had developed epilepsy, with 7 (7%) receiving AEDs. Infants/children on AEDs had higher MRI scores than those not on AEDs (median [interquartile range] 9 [8-11] vs. 2 [0-4]) and poorer outcomes. Nine (64%) of 14 children with epilepsy had cerebral palsy compared to 13 (11%) of 120 without epilepsy, and 10 (71%) of 14 children with epilepsy had adverse outcomes versus 23 (19%) of 120 survivors without epilepsy. The number of different AEDs given to control neonatal seizures, aEEG severity precooling, and MRI scores predicted childhood epilepsy. We report, in a regional cohort of infants cooled for perinatal asphyxia, 6% with epilepsy at 2 years (2% on AEDs

Jones, Chloe; Reilly, Colin

2016-04-01

The aim was to systematically review studies that have focused on symptoms of anxiety reported by parents of children (0-18 years) with epilepsy. PubMed was used to identify relevant studies. Selected studies were reviewed with respect to prevalence of above threshold scores and comparisons with controls on standardized measures of anxiety. Studies are also reported with respect to factors associated with parental anxiety, impact on child outcomes, and comparisons with studies that have included equivalent measures of symptoms of depression. Fifteen studies that met inclusion criteria were identified. None of the studies were population based. The percentage of parents scoring above cutoffs on standardized measures of anxiety was 9-58%. In comparison with parents of healthy controls, parents of children with epilepsy had higher mean scores in two of three studies where this was measured. Possible correlates of parental anxiety in childhood epilepsy that were considered varied widely across studies. Factors such as seizure frequency and use of antiepileptic drugs (AEDs) have been associated with parental anxiety in some but not all studies. With respect to child outcome, increased parental anxiety has been associated with lower quality of life and lower scores on adaptive behavior domains. Symptoms of anxiety are common among parents of children with epilepsy. There is a need for more systematic, representative studies to identify the prevalence of clinically significant anxiety and track the course of symptoms. Such studies will help to identify more clearly factors associated with parental anxiety and impact of symptoms on child and parent outcomes. Intervention studies are needed to evaluate approaches that target a reduction in symptoms and the potential impact on parental and child functioning. Furthermore, there is a need to evaluate the impact of antiepileptic therapies and interventions that focus on child neurobehavioral comorbidities on parental anxiety

Advancing the management of childhood epilepsies.

Childhood epilepsies comprise a heterogeneous group of disorders and syndromes that vary in terms of severity, prognosis and treatment requirements. Effective management requires early, accurate recognition and diagnosis, and a holistic approach that addresses each individual's medical and psychosocial needs within the context of their overall health status and quality of life. With increasing understanding of underlying aetiologies, new approaches to management and treatment are emerging. For example, genetic testing is beginning to provide a tool to aid differential diagnosis and a means of predicting predisposition to particular types of epilepsy. Despite the availability of an increasing number of antiepileptic drugs (AEDs)--due not only to the development of new AEDs, but also to changes in regulatory requirements that have facilitated clinical development--seizure control and tolerability continue to be suboptimal in many patients, and there is therefore a continuing need for new treatment strategies. Surgery and other non-pharmacological treatments (e.g. vagus nerve stimulation, ketogenic diet) are already relatively well established in paediatric epilepsy. New pharmacological treatments include generational advances on existing AEDs and AEDs with novel modes of action, and non-AED pharmacological interventions, such as immunomodulation. Emerging technologies include novel approaches allowing the delivery of medicinal agents to specific areas of the brain, and 'closed-loop' experimental devices employing algorithms that allow treatment (e.g., electrical stimulation) to be targeted both spatially and temporally. Although in early stages of development, cell-based approaches (e.g., focal targeting of adenosine augmentation) and gene therapy may also provide new treatment choices in the future.

There is increasing recognition that establishing a core set of outcomes to be evaluated and reported in trials of interventions for particular conditions will improve the usefulness of health research. There is no established core outcome set for childhood epilepsy. The aim of this work is to select a core outcome set to be used in evaluative research of interventions for children with rolandic epilepsy, as an exemplar of common childhood epilepsy syndromes. First we will identify what outcomes should be measured; then we will decide how to measure those outcomes. We will engage relevant UK charities and health professional societies as partners, and convene advisory panels for young people with epilepsy and parents of children with epilepsy. We will identify candidate outcomes from a search for trials of interventions for childhood epilepsy, statutory guidance and consultation with our advisory panels. Families, charities and health, education and neuropsychology professionals will be invited to participate in a Delphi survey following recommended practices in the development of core outcome sets. Participants will be able to recommend additional outcome domains. Over three rounds of Delphi survey participants will rate the importance of candidate outcome domains and state the rationale for their decisions. Over the three rounds we will seek consensus across and between families and health professionals on the more important outcomes. A face-to-face meeting will be convened to ratify the core outcome set. We will then review and recommend ways to measure the shortlisted outcomes using clinical assessment and/or patient-reported outcome measures. Our methodology is a proportionate and pragmatic approach to expediently produce a core outcome set for evaluative research of interventions aiming to improve the health of children with epilepsy. A number of decisions have to be made when designing a study to develop a core outcome set including defining the scope

Nearly 10 years after its introduction into the market, the significance of lacosamide in genetic generalized epilepsies is still unclear. Its new mode of action may qualify lacosamide as a therapeutic agent in this entity, but only a limited number of cases have been published so far. To describe the efficacy of lacosamide as treatment in a patient with the absence status epilepticus. We report on a 28-year-old woman with genetic generalized epilepsy who suffered recurrent absence status epilepticus during video-EEG-monitoring. After treatment failure of first- and second-line medication, lacosamide was administered. The outcome in this patient was evaluated, and a systematic literature review was performed for the use of lacosamide in the absence status epilepticus. After application of 400 mg lacosamide intravenously, the absence status epilepticus terminated within 30 minutes. No further seizures or epileptiform discharges reoccurred until the end of video-EEG-Monitoring 3 days later. The role of lacosamide as a therapeutic option in patients with the absence status epilepticus is unclear. Only two cases have been reported so far with conflicting results. Further randomized controlled studies are required to validate the relevance of lacosamide as treatment for status epilepticus in genetic generalized and the absence epilepsy. © 2018 John Wiley & Sons A/S.

Absence epilepsy (AE) in humans and the genetic AE model in WAG/Rij rats are both associated with abnormalities in sleep architecture that suggest insufficiency of the sleep-promoting mechanisms. In this study we compared the functionality of sleep-active neuronal groups within two well-established sleep-promoting sites, the ventrolateral and median preoptic nuclei (VLPO and MnPN, respectively), in WAG/Rij and control rats. Neuronal activity was assessed using c-Fos immunoreactivity and chron...

KANSL1 variation is not a major contributing factor in self-limited focal epilepsy syndromes of childhood.

Directory of Open Access Journals (Sweden)

Kenneth A Myers

Full Text Available KANSL1 haploinsufficiency causes Koolen-de Vries syndrome (KdVS, characterized by dysmorphic features and intellectual disability; amiable personality, congenital malformations and seizures also commonly occur. The epilepsy phenotypic spectrum in KdVS is broad, but most individuals have focal seizures with some having a phenotype resembling the self-limited focal epilepsies of childhood (SFEC. We hypothesized that variants in KANSL1 contribute to pathogenesis of SFEC.We screened KANSL1 for single nucleotide variants in 90 patients with SFEC. We then screened a cohort of 208 patients with two specific SFEC syndromes, childhood epilepsy with centrotemporal spikes (CECTS and atypical childhood epilepsy with centrotemporal spikes (ACECTS for KANSL1 variants. The second cohort was also used to evaluate minor allelic variants that appeared overrepresented in the initial cohort.One variant, p.Lys104Thr, was predicted damaging and appeared overrepresented in our 90-patient cohort compared to Genome Aggregation Database (gnomAD allele frequency (0.217 to 0.116, with no homozygotes in gnomAD. However, there was no difference in p.Lys104Thr allele frequency in the follow-up CECTS/ACECTS cohort and controls. Four rare KANSL1 variants of uncertain significance were identified in the CECTS/ACECTS cohort.Our data do not support a major role for KANSL1 variants in pathogenesis of SFEC.

Respiratory arrest at the onset of idiopathic childhood occipital epilepsy of Gastaut.

Occipital lobe epilepsy of childhood includes two entities: Panayiotopoulos syndrome in pre-school children, and idiopathic childhood occipital epilepsy of Gastaut (ICOEG) in school-age children. The typical initial manifestation of the former is vomiting, and that of the latter is visual hallucinations. Ictal cardiopulmonary arrest at initial presentation has been reported for Panayiotopoulos syndrome, but not for ICOEG. We document a 7-year-old previously healthy girl who experienced an acute elemental visual hallucination of seeing insects, followed by a new-onset generalized seizure. Upon arrival at the local hospital, she was unconscious and soon thereafter, developed respiratory arrest. She was resuscitated and initiated on mechanical ventilation. An electroencephalogram taken three days after seizure cessation showed frequent occipital spikes, consistent with the diagnosis of ICOEG. The sequence of acute elementary visual hallucination followed by a motor seizure, and then witnessed respiratory arrest illustrated occurrence of life-threatening autonomic involvement at initial onset in ICOEG. We speculate that the epileptic propagation from the occipital lobes eventually compromised the respiratory center in the brainstem. The possibility of occipital lobe epilepsy should be considered in school-age children presenting with acute visual hallucination followed by respiratory arrest. Such a presentation should prompt an urgent electroencephalogram and initiation of antiepileptic treatment if indicated. Copyright © 2017 The Japanese Society of Child Neurology.

Academic skills in the long term after epilepsy surgery in childhood.

Puka, Klajdi; Smith, Mary Lou

2016-09-01

We evaluated the progression of academic skills in a cohort of patients who underwent, or were considered for, epilepsy surgery in childhood, four to eleven years before. The few existing studies that have evaluated cognitive function in the long term after surgery have examined intelligence and memory. Participants were 97 patients with childhood-onset intractable epilepsy; 61 had undergone resective epilepsy surgery. Participants completed standardized tests of reading, spelling, arithmetic, and intelligence at baseline and, on average, 7years after. Surgical patients were additionally assessed one year postsurgery. At baseline and long-term follow-up, 61% and 69% of patients, respectively, scored at least one standard deviation below normative data in at least one academic domain. Evaluation of change over time while controlling for IQ showed that arithmetic scores were lower at long-term follow-up in comparison with those at baseline among all patient groups, whereas reading and spelling scores remained unchanged. Few advantages were associated with seizure control. Multiple regression analyses found that older age at surgery, cessation of antiepileptic medications, improved IQ, and low baseline scores were independently associated with improvement in some academic domains among all patient groups. We found that arithmetic scores were lower at long-term follow-up, suggesting a lack of ongoing development or deterioration in skills. Reading and spelling scores remained stable suggesting that patients made gains in abilities at a rate expected for their increase in age; this finding contrasts with recent short-term outcome studies identifying significantly lower scores over time in these areas.

To investigate the clinical, neurophysiologic characteristics and therapeutic considerations of epileptic negative myoclonus (ENM) in atypical benign partial epilepsy of childhood (ABPE). Video-EEG monitoring with outstretched arm tests were carried out in 17 patients, and 9 of them were examined with simultaneous electromyography (EMG). The ENM manifestations, electrophysiologic features and responses to antiepileptic drugs (AED) were analyzed. Seventeen patients were diagnosed as having benign childhood epilepsy with centrotemporal spikes (BECT) during the early course of the disease and were treated with AED. During the course of the disease, hand trembling, objects dropping, head nodding and instability during standing might be clues for ENM occurrence. ENM had been confirmed in our patients by outstretched arm tests during video-EEG recording. The ictal EEG showed that high-amplitude spikes followed by a slow wave over the contralateral motor areas. This was further confirmed by time-locked silent EMG in 9 patients. During ENM occurrence or recurrence, the habitual seizures and interictal discharges were exaggerated. Atypical absence seizures also occurred in 6 patients. The alteration of therapeutic options of AED relating to ENM appearance in some patients included the add-on therapy with carbamazepine (CBZ), oxcarbazepine, phenobarbital, or withdrawal of valproate (VPA). ENM was controlled in most cases by using VPA, clonazepam (CZP) and corticosteroid with different combination. ENM could occur during the course of ABPE. Outstretching arm tests during video-EEG monitoring in combination with EMG was essential to confirm ENM. The ENM occurrence was always associated with the frequency increasing of habitual seizures and the aggravation of interictal discharges. Some AED such as CBZ might induce ENM. VPA, benzodiazepines and corticosteroid with different combination were relatively effective in treatment of ENM.

The availability of glucose, and its glycolytic product lactate, for cerebral energy metabolism is regulated by specific brain transporters. Inadequate energy delivery leads to neurologic impairment. Haploinsufficiency of the glucose transporter GLUT1 causes a characteristic early onset encephalopathy, and has recently emerged as an important cause of a variety of childhood or later-onset generalized epilepsies and paroxysmal exercise-induced dyskinesia. We explored whether mutations in the genes encoding the other major glucose (GLUT3) or lactate (MCT1/2/3/4) transporters involved in cerebral energy metabolism also cause generalized epilepsies. A cohort of 119 cases with myoclonic astatic epilepsy or early onset absence epilepsy was screened for nucleotide variants in these five candidate genes. No epilepsy-causing mutations were identified, indicating that of the major energetic fuel transporters in the brain, only GLUT1 is clearly associated with generalized epilepsy.

Role of genetics in the etiopathogenesis of genetic generalized epilepsy: A review of current literature

Full Text Available Until recently, genetic generalized epilepsy (GGE was believed to be of presumed genetic etiology with no identifiable genetic mutation or demonstrable epigenetic abnormality. A wide range of epileptic disorders has clue for an inherited susceptibility. Monogenic disorders associated with epilepsy mental retardation and structural brain lesion typified by heterotopias, tuberous sclerosis, and progressive myoclonus epilepsies account for about 1% of epilepsies. This review focuses on the role of genetic mutations and epigenetic rearrangements in the pathophysiologic mechanism of GGE. To achieve this; PubMed, EMBASE, and Google Scholar were systematically and comprehensively searched using keywords (“epilepsy” “juvenile myoclonic epilepsy (JME,” “typical absences,” “idiopathic generalized epilepsy,” “JME,” “juvenile absence epilepsy,” “childhood absence epilepsy” “generalized tonic-clonic seizure” “GTCS”. Most GGE has evidence of underlying genetic inheritance. Recent animal studies have shown that early detection and treatment of genetic generalized epilepsies can alter the phenotypic presentation in rodents. These findings suggest a critical period in epileptogenesis, during which spike-and-wave seizures can be suppressed, leading to chronic changes in the brain (epileptogenesis and the preceding dysfunctions may, therefore, be targeted using therapeutic approaches that may either delay or inhibit the transition to active epileptic attack. The interplay between genetic mutations and epigenetic rearrangements play important roles in the development of GCE and that this process, especially at crucial developmental periods, is very susceptible to environmental modulations.

Understanding the transition of brain activity towards an absence seizure is a challenging task. In this paper, we use recurrence quantification analysis to indicate the deterministic dynamics of EEG series at the seizure-free, pre-seizure and seizure states in genetic absence epilepsy rats. The determinism measure, DET, based on recurrence plot, was applied to analyse these three EEG datasets, each dataset containing 300 single-channel EEG epochs of 5-s duration. Then, statistical analysis of the DET values in each dataset was carried out to determine whether their distributions over the three groups were significantly different. Furthermore, a surrogate technique was applied to calculate the significance level of determinism measures in EEG recordings. The mean (+/-SD) DET of EEG was 0.177+/-0.045 in pre-seizure intervals. The DET values of pre-seizure EEG data are significantly higher than those of seizure-free intervals, 0.123+/-0.023, (Pdeterminism in EEG epochs was present in 25 of 300 (8.3%), 181 of 300 (60.3%) and 289 of 300 (96.3%) in seizure-free, pre-seizure and seizure intervals, respectively. Results provide some first indications that EEG epochs during pre-seizure intervals exhibit a higher degree of determinism than seizure-free EEG epochs, but lower than those in seizure EEG epochs in absence epilepsy. The proposed methods have the potential of detecting the transition between normal brain activity and the absence seizure state, thus opening up the possibility of intervention, whether electrical or pharmacological, to prevent the oncoming seizure.

Thrombospondins, which are known to interact with the α 2 δ subunit of voltage-sensitive calcium channels to stimulate the formation of excitatory synapses, have recently been implicated in the process of epileptogenesis. No studies have been so far performed on thrombospondins in models of absence epilepsy. We examined whether expression of the gene encoding for thrombospondin-1 was altered in the brain of WAG/Rij rats, which model absence epilepsy in humans. In addition, we examined the frequency of genetic variants of THBS1 in a large cohort of children affected by idiopathic/genetic generalized epilepsies (IGE/GGEs). We measured the transcripts of thrombospondin-1 and α 2 δ subunit, and protein levels of α 2 δ, Rab3A, and the vesicular glutamate transporter, VGLUT1, in the somatosensory cortex and ventrobasal thalamus of presymptomatic and symptomatic WAG/Rij rats and in two control strains by real-time polymerase chain reaction (PCR) and immunoblotting. We examined the genetic variants of THBS1 and CACNA2D1 in two independent cohorts of patients affected by IGE/GGE recruited through the Genetic Commission of the Italian League Against Epilepsy (LICE) and the EuroEPINOMICS-CoGIE Consortium. Thrombospondin-1 messenger RNA (mRNA) levels were largely reduced in the ventrobasal thalamus of both presymptomatic and symptomatic WAG/Rij rats, whereas levels in the somatosensory cortex were unchanged. VGLUT1 protein levels were also reduced in the ventrobasal thalamus of WAG/Rij rats. Genetic variants of THBS1 were significantly more frequent in patients affected by IGE/GGE than in nonepileptic controls, whereas the frequency of CACNA2D1 was unchanged. These findings suggest that thrombospondin-1 may have a role in the pathogenesis of IGE/GGEs. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

PET has added valuable information to our knowledge of the human epilepsies. The most important observations have been the identification of localized regions of interictal cerebral dysfunction in patients with partial epilepsy, revealed with PET as local hypometabolism, hypoperfusion, or (in one study) enhanced {mu}opiate receptor binding. The following general conclusions about the anatomy of epilepsy can be drawn from interictal PET studies: (1) interictal neuronal dysfunction is not limited to the site of ictal onset, nor to brain areas immediately adjacent to structural damage, (2) temporal lobe dysfunction is most commonly encountered, usually in association with primary epileptogenic lesions in mesial temporal structures, but also on occasion with lateral temporal or extratemporal epileptogenic lesions which preferentially propagate to mesial temporal structures to give rise to complex partial seizures. It is now accepted that interictal {sup 18}F-FDG PET correctly lateralises the primarily epileptic temporal lobe in approximately 70% of patients. As a consequence of inclusion of PET into the UCLA presurgical evaluation protocol, Engel et al. were able to operate on 28% of the patients without using invasive methods, (3) local isolated neocortical dysfunction associated with simple partial seizures is only rarely revealed by PET, (4) remote interictal cerebral dysfunction associated with complex partial seizures is not necessarily limited to the involved TL, since contralateral temporal, extemporal neocortical and cerebral dysfunction may also be seen, (5) a variety of anatomical patterns of interictal cerebral dysfunction occur in secondary generalized epilepsies, which may be related to symptoms and signs, (6) no diffuse or localized interictal cerebral dysfunction has been identified by PET in patients with primary generalized childhood absence seizures.

To examine the association between autism spectrum disorder (ASD) and epilepsy in children. A total of 190 children with ASD were enrolled. A self-designed questionnaire, Childhood Autism Rating Scale, and Autism Behavior Checklist were used to determine the association between ASD and epilepsy. Among the 190 children with ASD, 20 (10.5%) had epileptic seizures and 12 (6.3%) were diagnosed with epilepsy. The rates of abnormal physical development and hearing disorders before the age of one year were significantly higher in ASD children with epileptic seizures than in those without epileptic seizures (Pchildren diagnosed with epilepsy and those receiving epilepsy treatment had a significantly increased rate of abnormal physical development before the age of one year (Pchildren with epileptic seizures had poorer sensory responses and behavioral competencies than those without epileptic seizures (PEpilepsy treatment have a positive effect on behavioral competencies in ASD children (Pepilepsy in children. The possibility of the comorbidity between ASD and epilepsy may be assessed according to the status of growth and development before the age of one year, sensory responses and behavioral competencies, and the presence or absence of epileptic seizures.

The role of intracellular proteins in the pathogenesis of absence epilepsy were mentioned. These proteins are thought to be related to energy generation, signal transduction, inflammation processes and membrane conductance. The investigation of protein profile of the genetically epileptic rat brains was the main subject of this study. For this, a 2D-gel electrophoresis based comparative proteome analysis was performed using thalamus tissue of genetic absence epileptic WAG/Rij and age matched Wistar rats. Regulated spots displaying differences in their abundance were identified using MALDI-TOF/TOF. Among the six spots (DHRS9, BR44, HINT1, CREM, SPRE and PDIA3/ERp57) the highest mascot score was attributed to ERp57 a neuroprotective/neurodegenerative system associated protein. Western Blot analyses were performed to validate changes occurring at ERp57 in thalamus and also identify changes in fronto-parietal cortex. Reductions in the expression levels of ERp57 were detected in the thalamic and the fronto-parietal brain regions of the WAG/Rij rats in comparison to Wistar rats. Such difference might be associated with the pathogenic mechanisms dictating the absence epilepsy.

Childhood absence epilepsy (CAE) is often comorbid with behavioral and cognitive symptoms, including impaired visual memory. Genetic Absence Epilepsy Rats from Strasbourg (GAERS) is an animal model closely resembling CAE; however, cognition in GAERS is poorly understood. Crossmodal object recognition (CMOR) is a recently developed memory task that examines not only purely visual and tactile memory, but also requires rodents to integrate sensory information about objects gained from tactile exploration to enable visual recognition. Both the visual and crossmodal variations of the CMOR task rely on the perirhinal cortex, an area with dense expression of T-type calcium channels. GAERS express a gain-in-function missense mutation in the Cav3.2 T-type calcium channel gene. Therefore, we tested whether the T-type calcium channel blocker Z944 dose dependently (1, 3, 10mg/kg; i.p.) altered CMOR memory in GAERS compared to the non-epileptic control (NEC) strain. GAERS demonstrated recognition memory deficits in the visual and crossmodal variations of the CMOR task that were reversed by the highest dose of Z944. Electroencephalogram recordings determined that deficits in CMOR memory in GAERS were not the result of seizures during task performance. In contrast, NEC showed a decrease in CMOR memory following Z944 treatment. These findings suggest that T-type calcium channels mediate CMOR in both the GAERS and NEC strains. Future research into the therapeutic potential of T-type calcium channel regulation may be particularly fruitful for the treatment of CAE and other disorders characterized by visual memory deficits.

Evaluation of quality of life has become a frequently used method in treatment effects supervision. Quality of Life Childhood Epilepsy (QOLCE) questionnaire, which is completed by patients' parents, has been prepared for children with epilepsy. It enables to determine the quality of life in children aged 4-18 years. The aim of the study was to show the usefulness of QOLCE questionnaire in evaluating the quality of life of children with epilepsy. 160 epileptic children, aged 8-18 years and their parents were examined in the Chair and Department of Developmental Neurology, K. Marcinkowski University of Medical Sciences in Poznań. QOLCE questionnaire was completed by parents and "Young people and epilepsy" questionnaire was designed for children. Reliability index of the complete questionnaire in own research and in the original amounted to 0.93 Cronbach alpha coefficient. Epileptic, drug-resistant children constituted 28% of the examined group. Parents of children with controlled seizures evaluated children's functioning in analyzed areas of quality of life higher. 1. QOLCE questionnaire is a suitable tool to evaluate the quality of children's and adolescents' life. 2. The most significant differences in functioning of epileptic, drug-resistant patients and those with controlled seizures were observed in areas of cognitive processes and social activity.

To evaluate the possibility of early syndrome classification of idiopathic partial epilepsies in children at the first seizure. In this observational study we prospectively evaluated 298 patients, aged between 1 month and 17 years and consecutively referred for the first unprovoked focal seizure. The whole cohort included 133 patients; the final analysis was carried out on 107 (59 males) individuals. Age at the first seizure ranged between 2.3 and 13.0 years. Clinical and EEG data of all patients were independently reviewed by two medical doctors. Patients were followed-up for at least 5 years, with a mean period of follow-up of 6.9 years. After the first seizure, a specific syndrome could be diagnosed in eighty (74.7%) children. In particular, Childhood Epilepsy with Centro-Temporal Spikes (CECTS) 42.9% of cases, Panayiotopoulos Syndrome (PS) 28.9%, idiopathic childhood occipital epilepsy of Gastaut (ICOE-G) 2.8%. Unclassified cases were 25.4%. At the end of the follow-up, the diagnosis was confirmed in 72 of 80 children (90%): BCECTS 89% of patients, PS 90% and ICOE-G 100%: among the unclassified cases, in 11 patients (40.7%) the diagnosis did not change, whereas 16 patients (59.3%) evolved into other syndromes or into atypical forms. At the onset an initial diagnosis is possible in the majority of cases; epilepsy syndromes can be identified at the time of the initial diagnosis and at follow up this diagnosis has not to be revised in 90% of the cases.

The potential cognitive and psychosocial effects of childhood epilepsy have significant implications for a child's self-image and academic achievement. This study focuses on a 10-week karate program for children and adolescents with epilepsy aimed at increasing social confidence, self-concept, and quality of life, as well as reducing parental anxiety. Eleven children (8-16 years old) and their parents participated in this questionnaire study, and complete data were available for nine of these families. Measures consisted of the Piers-Harris Children's Self-Concept Scale, the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire, and the Parental Stress Index. By parental report, significant improvement in memory function and largely positive trends in quality of life on multiple subscales were observed. By child report, intellectual self-esteem and social confidence also improved. Parental stress decreased, although not significantly, suggesting a potential benefit and indicating a role for future interventions targeting family anxiety.

Idiopathic generalised epilepsy (IGE) is subdivided into syndromes based on clinical and EEG features. PURPOSE: The aim of this study was to characterise all cases of IGE with supportive EEG abnormalities in terms of gender differences, seizure types reported, IGE syndromes, family history of epilepsy and EEG findings. We also calculated the limited duration prevalence of IGE in our cohort. METHODS: Data on abnormal EEGs were collected retrospectively from two EEG databases at two tertiary referral centres for neurology. Clinical information was obtained from EEG request forms, standardised EEG questionnaires and medical notes of patients. RESULTS: two hundred twenty-three patients met our inclusion criteria, 89 (39.9%) male and 134 (60.1%) females. Tonic clonic seizures were the most common seizure type reported, 162 (72.65%) having a generalised tonic clonic seizure (GTCS) at some time. IGE with GTCS only (EGTCSA) was the most common syndrome in our cohort being present in 94 patients (34 male, 60 female), with 42 (15 male, 27 female) patients diagnosed with Juvenile myoclonic epilepsy (JME), 23 (9 male, 14 female) with Juvenile absence epilepsy (JAE) and 20 (9 male, 11 female) with childhood absence epilepsy (CAE). EEG studies in all patients showed generalised epileptiform activity. CONCLUSIONS: More women than men were diagnosed with generalised epilepsy. Tonic clonic seizures were the most common seizure type reported. EGTCSA was the most frequent syndrome seen. Gender differences were evident for JAE and JME as previously reported and for EGTCSA, which was not reported to date, and reached statistical significance for EGTCA and JME.

Full Text Available Abstract Background Measuring quality of life (QOL helps to delineate mechanisms underlying the interaction of disease and psychosocial factors. In adults, epileptic foci in the left temporal lobe led to lower QOL and higher depression and anxiety as compared to the right-sided foci. No study addressed the development of QOL disturbances depending on the lateralization of epileptogenic focus. The objective of our study was to examine QOL in children with lateralized epileptiform discharges. Methods Thirty-one parents of children with epilepsy filled the Health-Related Quality of Life in Childhood Epilepsy Questionnaire (QOLCE. Fifteen children had foci in the left hemisphere and sixteen in the right, as verified with Electroencephalography (EEG examinations. Results We found a significant correlation between foci lateralization and reduced QOL (Spearman's rho = 0.361, p Conclusions We demonstrated for the first time that in children left- and right-hemispheric foci were associated with discordant QOL scores. Unlike in adults, foci in the right hemisphere led to worse emotional and social functioning demonstrating that seizures impact the brain differentially during development.

Benign occipital epilepsy of childhood: Panayiotopoulos syndrome in a 3 year old child

2014-11-01

Full Text Available Panayiotopoulos syndrome (PS is a relatively frequent and benign epileptic syndrome seen in children in the age group of 3-6 years and is characterised by predominantly autonomic symptoms and/or simple motor focal seizures followed or not by impairment of consciousness. Although multifocal spikes with high amplitude sharp-slow wave complexes at various locations can be present in the EEG, interictal electroencephalogram (EEG in children with this particular type of epilepsy characteristically shows occipital spikes. This syndrome has known to be a masquerader and can imitate gastroenteritis, encephalitis, syncope, migraine, sleep disorders or metabolic diseases. In the absence of thorough knowledge of types of benign epilepsy syndromes and their various clinical presentations, epilepsy such as PS can be easily missed. The peculiar aspects of this type of epilepsy in children should be known not only by paediatricians but also by general doctors because a correct diagnosis would avoid aggressive interventions and concerns on account of its benign outcome. In this case study, we report a case of PS in a 3 year old child.

The annual incidence of childhood and adolescence epilepsy ranges from 41 to 97 diagnoses per 100,000 people in western Countries, with a reported decline over time. We aimed at studying the incidence of epilepsy in children and adolescents (1 month to 14 years) and its temporal trend in the province of Ferrara, northern Italy. We implemented a community-based prospective multi-source registry. All children with newly diagnosed epilepsy in the period 1996-2005 were recorded. The incidence rate of newly diagnosed epilepsy in the considered age range was 57 per 100,000 person-years, (95% CI: 49.3-65.9), with a peak in the first year of life (109.4; 95% CI: 69.4-164.1), without differences between the two gender. The estimates were significantly lower than those observed previously (97.3; 95% CI: 81.9-115.7). Incidence rates for epilepsy in the Italian population aged 1 month to 14 years are in line with those of other European and Northern American Countries. The incidence of childhood epilepsy has declined over time in our area. A reduced impact of serious perinatal adverse events could partly explain the decline. © 2011 The Author(s).

The aim of this study was to validate the newly developed shortened Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) in a sample of children with drug-resistant epilepsy. Data came from 136 children enrolled in the Impact of Pediatric Epilepsy Surgery on Health-Related Quality of Life Study (PEPSQOL), a multicenter prospective cohort study. Confirmatory factor analysis was used to assess the higher-order factor structure of the QOLCE-55. Convergent and divergent validity was assessed by correlating subscales of the KIDSCREEN-27 with the QOLCE-55. Measurement equivalence of the QOLCE-55 was evaluated using multiple-group confirmatory factor analysis of children with drug-resistant epilepsy from PEPSQOL versus children with new-onset epilepsy from HERQULES (Health-Related Quality of Life in Children with Epilepsy Study). The higher-order factor structure of the QOLCE-55 demonstrated adequate fit: Comparative Fit Index (CFI) = 0.948; Tucker-Lewis Index (TLI) = 0.946; Root Mean Square of Approximation (RMSEA) = 0.060 (90% confidence interval [CI] 0.054-0.065); Weighted Root Mean Square Residuals (WRMR) = 1.247. Higher-order factor loadings were strong, ranging from λ = 0.74 to 0.81. Internal consistency reliability was excellent (α = 0.97, subscales α > 0.82). QOLCE-55 subscales demonstrated moderate to strong correlations with similar subscales of the KIDSCREEN-27 (ρ = 0.43-0.75) and weak to moderate correlations with dissimilar subscales (ρ = 0.25-0.42). The QOLCE-55 demonstrated partial measurement equivalence at the level of strict invariance - χ 2 (2,823) = 3,727.9, CFI = 0.961, TLI = 0.962, RMSEA = 0.049 (0.044, 0.053), WRMR = 1.834. The findings provide support for the factor structure of the QOLCE-55 and contribute to its robust psychometric profile as a reliable and valid measure. Researchers and health practitioners should consider the QOLCE-55 as a viable option for reducing respondent burden when assessing health-related quality of life

Attention-deficit/hyperactivity disorder (ADHD) is commonly observed in children with epilepsy. However, factors associated with the development of ADHD and which might help to guide its therapeutic management, remain an issue of debate. We conducted a multicenter prospective observational study that included children, aged 6-16 years, with both epilepsy and ADHD according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. After inclusion, patients entered a 12-16 week follow-up period during which they were either treated with methylphenidate or they did not receive specific ADHD treatment. ADHD was evaluated with the ADHD Rating Scale-IV. One hundred sixty-seven patients were included, of which 91 were seizure-free during the preinclusion baseline period. At inclusion, the ADHD Rating Scale-IV total score was 30.4 ± (standard deviation) 9.2, the inattentive subscore was 17.3 ± 4.4, and the hyperactive subscore was 13.2 ± 6.6. We did not detect any difference of ADHD Rating Scale-IV scores across patients' age or gender, age at epilepsy onset, epilepsy syndrome, seizure frequency, or number of ongoing antiepileptic drugs. Methylphenidate was initiated in 61 patients, including 55 in whom a follow-up evaluation was available. At the last follow-up, 41 patients (75%) treated with methylphenidate and 39 (42%) of those who did not received ADHD therapy demonstrated ≥25% decrease of ADHD Rating Scale-IV total score (p < 0.001). Response to methylphenidate was greater in girls but was not influenced by any epilepsy-related variables. We did not detect any epilepsy-related factor associated with the severity of ADHD. Twenty-five percent of patients did not respond to methylphenidate. A better understanding of the pathologic process that underlies ADHD development in childhood epilepsy might be required to improve therapeutic strategies.

Absence epilepsy (AE) in humans and the genetic AE model in WAG/Rij rats are both associated with abnormalities in sleep architecture that suggest insufficiency of the sleep-promoting mechanisms. In this study we compared the functionality of sleep-active neuronal groups within two well-established sleep-promoting sites, the ventrolateral and median preoptic nuclei (VLPO and MnPN, respectively), in WAG/Rij and control rats. Neuronal activity was assessed using c-Fos immunoreactivity and chronic single-unit recording techniques. We found that WAG/Rij rats exhibited a lack of sleep-associated c-Fos activation of GABAergic MnPN and VLPO neurons, a lower percentage of MnPN and VLPO cells increasing discharge during sleep and reduced firing rates of MnPN sleep-active neurons, compared to non-epileptic rats. The role of sleep-promoting mechanisms in pathogenesis of absence seizures was assessed in non-epileptic rats using electrical stimulation and chemical manipulations restricted to the MnPN. We found that fractional activation of the sleep-promoting system in waking was sufficient to elicit absence-like seizures. Given that reciprocally interrelated sleep-promoting and arousal neuronal groups control thalamocortical excitability, we hypothesize that malfunctioning of sleep-promoting system results in impaired ascending control over thalamocortical rhythmogenic mechanisms during wake-sleep transitions thus favoring aberrant thalamocortical oscillations. Our findings suggest a pathological basis for AE-associated sleep abnormalities and a mechanism underlying association of absence seizures with wake-sleep transitions.

Reoperations account for >10% in pediatric epilepsy surgery cohorts, and they are especially relevant in young children with catastrophic epilepsy. To determine surgical outcomes and their predictive factors in reoperations for refractory epilepsy in childhood. We retrospectively analyzed presurgical findings, resections, and outcomes of 23 consecutive children who underwent reoperations from 2000 to 2011. Etiology included cortical dysplasia with/without glioneuronal tumor in 19 patients (83%), sole glioneuronal tumor in 2, and tuberous sclerosis and Rasmussen encephalitis in 1 each. The reasons for the failure of the initial surgery were functional considerations in 8 (35%), incorrect delineation of the epileptogenic zone in 8 (35%), and resection not performed as initially planned in 7 (30%) cases. Final procedures included 8 (35%) intralobar, 8 (35%) multilobar resections, and 7 (30%) hemispherotomies. Following reoperations, 14 (61%) patients were seizure free, 6 (26%) showed significant or worthwhile improvement, and 3 (13%) did not respond to surgery. Six of 8 patients who underwent the first resection before the age of 3 years, 6 of 8 whose first resection was limited by functional considerations, and all 7 with hemispherotomy as the final resection achieved seizure freedom after reoperation. Reoperation is particularly beneficial for selected children with refractory epilepsy associated with cortical dysplasia that did not respond to an initial limited and/or early resection but achieved seizure freedom after extensive procedures. When indicated, reoperation should be performed at the youngest possible age to profit from higher functional plasticity in compensating for neurological deficit.

Estimate the causes and risk of death, specifically seizure related, in children followed from onset of epilepsy and to contrast the risk of seizure-related death with other common causes of death in the population. Mortality experiences from 4 pediatric cohorts of newly diagnosed patients were combined. Causes of death were classified as seizure related (including sudden unexpected death [SUDEP]), natural causes, nonnatural causes, and unknown. Of 2239 subjects followed up for >30 000 person-years, 79 died. Ten subjects with lethal neurometabolic conditions were ultimately excluded. The overall death rate (per 100 000 person-years) was 228; 743 in complicated epilepsy (with associated neurodisability or underlying brain condition) and 36 in uncomplicated epilepsy. Thirteen deaths were seizure-related (10 SUDEP, 3 other), accounting for 19% of all deaths. Seizure-related death rates were 43 overall, 122 for complicated epilepsy, and 14 for uncomplicated epilepsy. Death rates from other natural causes were 159, 561, and 9, respectively. Of 48 deaths from other natural causes, 37 were due to pneumonia or other respiratory complications. Most excess death in young people with epilepsy is not seizure-related. Mortality is significantly higher compared with the general population in children with complicated epilepsy but not uncomplicated epilepsy. The SUDEP rate was similar to or higher than sudden infant death syndrome rates. In uncomplicated epilepsy, sudden and seizure-related death rates were similar to or higher than rates for other common causes of death in young people (eg, accidents, suicides, homicides). Relating the risk of death in epilepsy to familiar risks may facilitate discussions of seizure-related mortality with patients and families.

This study examined patterns of syndrome-specific problems in behavior and competence in children with new- or recent-onset epilepsy compared with healthy controls. Research participants consisted of 205 children aged 8-18, including youth with recent-onset epilepsy (n=125, 64 localization-related epilepsy [LRE] and 61 idiopathic generalized epilepsy [IGE]) and healthy first-degree cousin controls (n=80). Parents completed the Child Behavior Checklist for children aged 6-18 (CBCL/6-18) from the Achenbach System of Empirically Based Assessment (ASEBA). Dependent variables included Total Competence, Total Problems, Total Internalizing, Total Externalizing, and Other Problems scales. Comparisons of children with LRE and IGE with healthy controls were examined followed by comparisons of healthy controls with those having specific epilepsy syndromes of LRE (BECTS, Frontal/Temporal Lobe, and Focal NOS) and IGE (Absence, Juvenile Myoclonic, and IGE NOS). Children with LRE and/or IGE differed significantly (pcompetence (Total Competence including School and Social). Similarly, children with specific syndromes of LRE and IGE differed significantly (pcompetence (Total Competence including School). Only on the Thought Problems scale were there syndrome differences. In conclusion, children with recent-onset epilepsy present with significant behavioral problems and lower competence compared with controls, with little syndrome specificity whether defined broadly (LRE and IGE) or narrowly (specific syndromes of LRE and IGE).

LGI2 truncation causes a remitting focal epilepsy in dogs.

Directory of Open Access Journals (Sweden)

Full Text Available One quadrillion synapses are laid in the first two years of postnatal construction of the human brain, which are then pruned until age 10 to 500 trillion synapses composing the final network. Genetic epilepsies are the most common neurological diseases with onset during pruning, affecting 0.5% of 2-10-year-old children, and these epilepsies are often characterized by spontaneous remission. We previously described a remitting epilepsy in the Lagotto romagnolo canine breed. Here, we identify the gene defect and affected neurochemical pathway. We reconstructed a large Lagotto pedigree of around 34 affected animals. Using genome-wide association in 11 discordant sib-pairs from this pedigree, we mapped the disease locus to a 1.7 Mb region of homozygosity in chromosome 3 where we identified a protein-truncating mutation in the Lgi2 gene, a homologue of the human epilepsy gene LGI1. We show that LGI2, like LGI1, is neuronally secreted and acts on metalloproteinase-lacking members of the ADAM family of neuronal receptors, which function in synapse remodeling, and that LGI2 truncation, like LGI1 truncations, prevents secretion and ADAM interaction. The resulting epilepsy onsets at around seven weeks (equivalent to human two years, and remits by four months (human eight years, versus onset after age eight in the majority of human patients with LGI1 mutations. Finally, we show that Lgi2 is expressed highly in the immediate post-natal period until halfway through pruning, unlike Lgi1, which is expressed in the latter part of pruning and beyond. LGI2 acts at least in part through the same ADAM receptors as LGI1, but earlier, ensuring electrical stability (absence of epilepsy during pruning years, preceding this same function performed by LGI1 in later years. LGI2 should be considered a candidate gene for common remitting childhood epilepsies, and LGI2-to-LGI1 transition for mechanisms of childhood epilepsy remission.

Measuring quality of life (QOL) helps to delineate mechanisms underlying the interaction of disease and psychosocial factors. In adults, epileptic foci in the left temporal lobe led to lower QOL and higher depression and anxiety as compared to the right-sided foci. No study addressed the development of QOL disturbances depending on the lateralization of epileptogenic focus. The objective of our study was to examine QOL in children with lateralized epileptiform discharges. Thirty-one parents of children with epilepsy filled the Health-Related Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). Fifteen children had foci in the left hemisphere and sixteen in the right, as verified with Electroencephalography (EEG) examinations. We found a significant correlation between foci lateralization and reduced QOL (Spearman's rho = 0.361, p < 0.046). Children with right hemispheric foci exhibited lower overall QOL, particularly in five areas: anxiety, social-activities, stigma, general-health, and quality-of-life. We demonstrated for the first time that in children left- and right-hemispheric foci were associated with discordant QOL scores. Unlike in adults, foci in the right hemisphere led to worse emotional and social functioning demonstrating that seizures impact the brain differentially during development.

In this study, we aimed to evaluate the attentional and executive functions in patients with benign childhood epilepsy with centrotemporal spikes (BCECTS) with and without attention-deficit hyperactivity disorder (ADHD) compared with controls and compared with patients with ADHD without epilepsy. We evaluated 12 patients with BCECTS and ADHD (66.7% boys; mean age of 9.67years); 11 children with non-ADHD BCECTS (63.6% boys; mean age of 11.91years); 20 healthy children (75% boys; mean age of 10.15years); and 20 subjects with ADHD without epilepsy (60% boys; mean age of 10.9years). We used a comprehensive battery of neuropsychological tests to evaluate attentional and executive functions in their broad domains. Patients with BCECTS and ADHD had worse performance in Conners' Continuous Performance Test II (reaction time standard error [p=0.008], variability [p=0.033], perseverations [p=0.044] and in reaction time interstimuli interval [p=0.016]). Patients with ADHD showed worse performance in Trail Making Test B errors [p=0.012]. In conclusion, patients with BCECTS and ADHD had worse executive and attentional performance compared with controls than non-ADHD patients with BCECTS. Regardless of the presence of epilepsy, ADHD also negatively impacted executive and attentional functions but in different executive subdomains compared with patients with epilepsy.

The aim of this study was to examine measurement equivalence of the newly developed Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) across age, sex, and time in a representative sample of children with newly diagnosed epilepsy. Data come from 373 children enrolled in the Health-related Quality of Life in Children with Epilepsy Study (HERQULES), a multisite prospective cohort study. Measurement equivalence was examined using a multiple-group confirmatory factor analysis framework, whereby increasingly stringent parameter constraints are imposed on the model. Comparison groups were stratified based on age (4-7 years vs. 8-12 years), sex (male vs. female), and time (measurement of health-related quality of life at diagnosis vs. 24 months later). The QOLCE-55 demonstrated measurement equivalence at the level of strict invariance for each model tested--age: χ(2) (3,123) = 4,097.3, p QOLCE-55 are perceived similarly among groups stratified by age, sex, and time and provide further evidence supporting the validity of the scale in children with epilepsy. Health professionals and researchers should be confident that group comparisons made using the QOLCE-55 are unbiased and that any group differences detected are meaningful; that is, not related to differences in the interpretation of items by informants. Future research replicating these findings is encouraged. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

Full Text Available Background Epilepsy remains one of the most frequently occurring pediatric problems. Approximately 10-15% patients do not respond to conventional therapy. Topiramate as a novel antiepileptic drug has a broad spectrum activity, presumably indicative of multiple anti-seizure mechanisms. Previous studies of topiramate as adjunctive and monotherapy in adults have shown beneficial effects. The objective of this research was to evaluate the efficacy and tolerability of topiramate sprinkle monotherapy in pediatric epilepsy. Methods This experimental research was conducted in the Pediatric Neurology outpatient clinic department, Soetomo hospital, Surabaya, involving 18 consecutive subjects. Subjects meeting the inclusion criteria were treated with topiramate sprinkle adjusted dose. Seizure frequency and side effects were observed in weeks 1, 4, 8, 12, 16, 20 and 24, respectively. Electro encephalogram (EEG and laboratory examinations were performed prior to and after 6 months of treatment. The t-test for related samples and McNemar test were utilized for statistical analysis. Results A total of 15 subjects completed the study. Topiramate-treated patients showed a statistically significant difference of seizure frequency reduction from 2.7 ± 1.16 to 0.13 ± 0.51 (p=0.000 with 93.7% patients being seizure free in 20 weeks. EEG recordings did not differ statistically in decrement of epileptiform activity in 20% subjects. About 7% subjects developed drowsiness and 33.3% subjects suffered from appetite suppression in the initial treatment. Laboratory results showed no abnormalities. Conclusions There was reduction of seizure frequency and no EEG recording alterations after topiramate sprinkle monotherapy. Topiramate as a monotherapy is highly effcicacious in childhood epilepsy.

A Japanese version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-J) was developed using international guidelines as a QOL scale for childhood epilepsy; its reliability and validity were examined, focusing on Japanese pediatric epilepsy patients applicability. A pilot test questionnaire survey was conducted; involving parents of pediatric epilepsy patients aged 4-15 undergoing outpatient treatment. 278 responses were obtained and analyzed. Internal consistency for the 16 QOLCE-J subscales, except for , was sufficient, and a high overall coefficient α was obtained. The intraclass correlation coefficient was also high, supporting the test-retest reliability of this version. Associations among the subscales, high correlations of r>0.7 were observed among , , and , representing cognitive and behavioral aspects, and among these and . In contrast, correlations among others were moderate or weaker. Furthermore, correlations of r>0.35 were observed among the subscales of the SDQ (Strength and Difficulties Questionnaire) used as an external criterion and the QOLCE-J, confirming the criterion validity of the study version. Analysis of associations between the total QOLCE-J score and pathology of epilepsy, found significant correlation with age of onset and frequency of seizures, ADL, and antiepileptics side effects' symptoms. QOLCE has mostly been used in treatment resistant pediatric patients, the influence of interictal period presently observed, like antiepileptic side effects' symptoms; suggest usefulness for pediatric patients with seizures under control. The QOLCE-J with sufficient reliability and validity may be applicable as a QOL scale for Japanese children with epilepsy. Copyright © 2015 The Japanese Society of Child Neurology.

Sleep spindles are known to appear spontaneously in the thalamocortical neuronal network of the brain during slow-wave sleep; pathological processes in the thalamocortical network may be the reason of the absence epilepsy. The aim of the present work is to study developed changes in the time-frequency structure of sleep spindles during the progressive development of the absence epilepsy in WAG/Rij rats. EEG recordings were made at age 7 and 9 months. Automatic recognition and subsequent analysis of sleep spindles on the EEG were performed using the continuous wavelet transform. The duration of epileptic discharges and the total duration of epileptic activity were found to increase with age, while the duration of sleep spindles, conversely, decreased. In terms of the mean frequency, sleep spindles could be divided into three classes: `slow' (mean frequency 9.3Hz), `medium' (11.4Hz), and `fast' (13.5Hz). Slow and medium (transitional) spindles in five-month-old animals showed increased frequency from the beginning to the end of the spindle. The more intense the epilepsy is, the shorter are the durations of spindles of all types. The mean frequencies of `medium' and `fast' spindles were higher in rats with more intense signs of epilepsy. Overall, high epileptic activity in WAG/Rij rats was linked with significant changes in spindles of the transitional type, with less marked changes in the two traditionally identified types of spindle, slow and fast.

2018-03-01

In this article, we have traced back the history of typical absence seizures, from their initial clinical description to the more recent nosological position. The first description of absence seizures was made by Poupart in 1705 and Tissot in 1770. In 1824, Calmeil introduced the term "absences", and in 1838, Esquirol for the first time used the term petit mal. Reynolds instead used the term "epilepsia mitior" (milder epilepsy) and provided a comprehensive description of absence seizures (1861). In 1854, Delasiauve ranked absences as the seizure type with lower severity and introduced the concept of idiopathic epilepsy. Otto Binswanger (1899) discussed the role of cortex in the pathophysiology of "abortive seizures", whereas William Gowers (1901) emphasized the importance of a detailed clinical history to identify nonmotor seizures or very mild motor phenomena which otherwise may go unnoticed or considered not epileptic. At the beginning of the 20th Century, the term pyknolepsy was introduced, but initially was not universally considered as a type of epilepsy; it was definitely recognized as an epileptic entity only in 1945, based on electroencephalogram (EEG) recordings. Hans Berger, the inventor of the EEG, made also the first EEG recording of an atypical absence (his results were published only in 1933), whereas the characteristic EEG pattern was reported by neurophysiologists of the Harvard Medical School in 1935. The discovery of EEG made it also possible to differentiate absence seizures from so called "psychomotor" seizures occurring in temporal lobe epilepsy. Penfield and Jasper (1938) considered absences as expression of "centrencephalic epilepsy". Typical absences seizures are now classified by the International League Against Epilepsy among generalized nonmotor (absence) seizures. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available Management of epilepsy in elderly requires understanding the unique biochemical and pharmacological characteristics of these patients. Management decisions must be based on accurate classification of seizures or epilepsy syndromes, a thorough neurological assessment to define etiology, and a comprehensive assessment of the patient’s health and living situation. Concomitant illnesses such as neurological, psychiatric, metabolic, or cardiac disorders will require individualization of plans and instructions. Specific problems of treatment of epilepsy in the elderly compared to childhood patients are as follows: distinctive range of causes of epilepsy, distinctive differential diagnosis, concurrent pathologies unrelated to epilepsy, pharmacokinetic and pharmacodynamic differences, and distinctive psychosocial effects.

Epilepsy is a frequent chronic disease in children, having a strong impact on a child's psychosocial functioning. Effective therapy must take into account the wide range of physical, psychological and social needs of patients. The importance of assessing patients' quality of life is becoming increasingly acknowledged. In addition to providing better health care, it may reveal how the disease and its psychosocial outcome interact. Quality of life in epilepsy can be assessed most reliably by disease-specific measures. Health-Related Quality of Life in Childhood Epilepsy (QOLCE) is an English parental questionnaire for children aged between 4 and 18 years. It contains 87 questions that fall into five domains: physical function, emotional well-being, cognitive function, social function and behavioural function. The original scale has a well-grounded theoretical background and good psychometric properties. The aim of the study was to create a Polish version of QOLCE and evaluate its psychometric properties. Parents of 87 patients suffering from epilepsy were recruited in neurological clinics in the Warsaw area. Reliability was very high (Cronbach's alpha = 0.97). The construct validity was confirmed by the correlation between subscales of QOLCE and the Child Behaviour Checklist, as well as selected clinical measures of child's health (duration of disease: r=-0.22, p=0.02; duration of treatment: r=-0.20, p=0.04; number of hospitalizations: r=-0.24, p=0.02). All the psychometric properties were similar to those of the original scale. A Polish scale examining the quality of life was created that takes into account a wide range of psychosocial problems. We confirmed very high reliability and good validity, and thus we recommend the inventory for both research on and clinical diagnostics of Polish children with epilepsy.

This is the third of three papers that summarize the second symposium on Transition in Epilepsies held in Paris in June 2016. This paper focuses on treatment issues that arise during the course of childhood epilepsy and make the process of transition to adult care more complicated. Some AEDs used during childhood, such as stiripentol, vigabatrin, and cannabidiol, are unfamiliar to adult epilepsy specialists. In addition, new drugs are being developed for treatment of specific childhood onset epilepsy syndromes and have no indication yet for adults. The ketogenic diet may be effective during childhood but is difficult to continue in adult care. Regional adult epilepsy diet clinics could be helpful. Polytherapy is common for patients transitioning to adult care. Although these complex AED regimes are difficult, they are often possible to simplify. AEDs used in childhood may need to be reconsidered in adulthood. Rescue medications to stop prolonged seizures and clusters of seizures are in wide home use in children and can be continued in adulthood. Adherence/compliance is notoriously difficult for adolescents, but there are simple clinical approaches that should be helpful. Mental health issues including depression and anxiety are not always diagnosed and treated in children and young adults even though effective treatments are available. Attention deficit hyperactivity disorder and aggressive behavior disorders may interfere with transition and successful adulthood but these can be treated. For the majority, the adult social outcome of children with epilepsy is unsatisfactory with few proven interventions. The interface between pediatric and adult care for children with epilepsy is becoming increasingly complicated with a need for more comprehensive transition programs and adult epileptologists who are knowledgeable about special treatments that benefit this group of patients.

The term idiopathic focal epilepsies of childhood (IFE) is not formally recognised by the ILAE in its 2010 revision (Berg et al., 2010), nor are its members and boundaries precisely delineated. The IFEs are amongst the most commonly encountered epilepsy syndromes affecting children. They are fascinating disorders that hold many "treats" for both clinicians and researchers. For example, the IFEs pose many of the most interesting questions central to epileptology: how are functional brain networks involved in the manifestation of epilepsy? What are the shared mechanisms of comorbidity between epilepsy and neurodevelopmental disorders? How do focal EEG discharges impact cognitive functioning? What explains the age-related expression of these syndromes? Why are EEG discharges and seizures so tightly locked to slow-wave sleep? In the last few decades, the clinical symptomatology and the respective courses of many IFEs have been described, although they are still not widely appreciated beyond the specialist community. Most neurologists would recognise the core syndromes of IFE to comprise: benign epilepsy of childhood with centro-temporal spikes or Rolandic epilepsy (BECTS/RE); Panayiotopoulos syndrome; and the idiopathic occipital epilepsies (Gastaut and photosensitive types). The Landau-Kleffner syndrome and the related (idiopathic) epilepsy with continuous spikes and waves in sleep (CSWS or ESES) are also often included, both as a consequence of the shared morphology of the interictal discharges and their potential evolution from core syndromes, for example, CSWS from BECTS. Atypical benign focal epilepsy of childhood also has shared electro-clinical features warranting inclusion. In addition, a number of less well-defined syndromes of IFE have been proposed, including benign childhood seizures with affective symptoms, benign childhood epilepsy with parietal spikes, benign childhood seizures with frontal or midline spikes, and benign focal seizures of adolescence.

Genetic generalized epilepsy (GGE) is a common epilepsy syndrome that encompasses seizure disorders characterized by spike-and-wave discharges (SWDs). Pacemaker hyperpolarization-activated cyclic nucleotide-gated channels (HCN) are considered integral to SWD genesis, making them an ideal gene candidate for GGE. We identified HCN2 missense variants from a large cohort of 585 GGE patients, recruited by the Epilepsy Phenome-Genome Project (EPGP), and performed functional analysis using two-electrode voltage clamp recordings from Xenopus oocytes. The p.S632W variant was identified in a patient with idiopathic photosensitive occipital epilepsy and segregated in the family. This variant was also independently identified in an unrelated patient with childhood absence seizures from a European cohort of 238 familial GGE cases. The p.V246M variant was identified in a patient with photo-sensitive GGE and his father diagnosed with juvenile myoclonic epilepsy. Functional studies revealed that both p.S632W and p.V246M had an identical functional impact including a depolarizing shift in the voltage dependence of activation that is consistent with a gain-of-function. In contrast, no biophysical changes resulted from the introduction of common population variants, p.E280K and p.A705T, and the p.R756C variant from EPGP that did not segregate with disease. Our data suggest that HCN2 variants can confer susceptibility to GGE via a gain-of-function mechanism. © 2017 Wiley Periodicals, Inc.

Role of Neuroinflammation in Evolution of Childhood Epilepsy.

Science.gov (United States)

Koh, Sookyong

2018-01-01

Until a decade ago, epilepsy research had focused mainly on alterations of neuronal activities and excitability. Such neurocentric emphasis has neglected the role of glia and involvement of inflammation in the pathogenesis of epilepsy. It is becoming clear that immune and inflammatory reactions do occur in the brain despite the brain's lack of conventional lymphatic drainage and graft acceptance and the presence of vascular brain barrier that tightly regulates infiltration of blood monocytes and lymphocytes. The critical roles of brain-resident immune mediators and of brain-infiltrating peripheral leukocytes are increasingly recognized. Inflammatory processes, including activation of microglia and astrocytes and production of proinflammatory cytokines and related molecules, occur in human epilepsy as well as in experimental models of epilepsy. Immune mechanism that underlies evolution of drug-resistant epilepsy and epileptic encephalopathy represents a new target and will aid in development of novel immunotherapeutic drugs and therapies against the key constituents in immune pathways.

Age at epilepsy onset has a broad impact on brain plasticity and epilepsy pathomechanisms. Prolonged febrile seizures in early childhood (FS) constitute an initial precipitating insult (IPI) commonly associated with mesial temporal lobe epilepsy (MTLE). FS-MTLE patients may have early disease onset, i.e. just after the IPI, in early childhood, or late-onset, ranging from mid-adolescence to early adult life. The mechanisms governing early (E) or late (L) disease onset are largely unknown. In order to unveil the molecular pathways underlying E and L subtypes of FS-MTLE we investigated global gene expression in hippocampal CA3 explants of FS-MTLE patients submitted to hippocampectomy. Gene coexpression networks (GCNs) were obtained for the E and L patient groups. A network-based approach for GCN analysis was employed allowing: i) the visualization and analysis of differentially expressed (DE) and complete (CO) - all valid GO annotated transcripts - GCNs for the E and L groups; ii) the study of interactions between all the system’s constituents based on community detection and coarse-grained community structure methods. We found that the E-DE communities with strongest connection weights harbor highly connected genes mainly related to neural excitability and febrile seizures, whereas in L-DE communities these genes are not only involved in network excitability but also playing roles in other epilepsy-related processes. Inversely, in E-CO the strongly connected communities are related to compensatory pathways (seizure inhibition, neuronal survival and responses to stress conditions) while in L-CO these communities harbor several genes related to pro-epileptic effects, seizure-related mechanisms and vulnerability to epilepsy. These results fit the concept, based on fMRI and behavioral studies, that early onset epilepsies, although impacting more severely the hippocampus, are associated to compensatory mechanisms, while in late MTLE development the brain is less able to

After a seizure, individuals with epilepsy have reported diverse symptoms in the postictal period, especially motor and cognitive dysfunction. However, these phenomena have not been well characterized in children, and their impact on patient well-being is not understood. We hypothesized that in a subset of epilepsy patients, postictal symptoms would affect their ability to return to normal childhood activities. To test our hypothesis, a survey-based approach was used to characterize the type, frequency, and duration, as well as the impact of these symptoms on the ability of these children to return to their normal activities. In this prospective study, data were analyzed from 208 patients seen in the pediatric neurology outpatient clinic at the Alberta Children's Hospital. We found that 86% (179 out of 208) of respondents reported postictal symptoms, with the most common symptom category being fatigue, sleepiness, and/or tiredness (90%; 161 of 179). The greatest impact resulted from weakness or being unable to move normally, which prevented 78% of those affected (71 of 91) from returning to normal activities after a seizure. Children who had focal seizures were more likely to experience postictal fatigue, sleepiness, or tiredness (P = 0.01; Bonferroni corrected), but no other postictal symptoms were significantly associated with a specific seizure type or epilepsy syndrome. The results of this study further our understanding of the frequency, type, and duration of symptoms experienced in the postictal period and how these symptoms impact children with epilepsy. It is clear that postictal phenomena often occur after epileptic seizures and have a significant impact on the lives of children with epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

The early and late benign occipital epilepsies of childhood (BOEC) are described as two discrete electro-clinical syndromes, eponymously known as Panayiotopoulos and Gastaut syndromes. The purpose of this study was to identify predictors of failure to respond to the initial antiepileptic drug (AED). A total of 42 children with BOEC were enrolled. Predictive factors were analyzed by survival methods. Among the 42, 25 patients (59.5%) were boys and 17 (40.5%) were girls and the mean age at the seizure onset was 7.46 ± 2.65 years (4-14 years). Of the 42 patients, 34 (81.0%) were treated relatively successfully with the first AED treatment, and 8 (19.0%) were not responded initial AED treatment. There was no correlation between response to initial AED treatment and sex, consanguinity, epilepsy history of family, age of seizure onset, frequency of seizures, history of status epilepticus, duration of starting first treatment, findings on electroencephalogram. However, history of febrile seizure and type of BOEC were significantly associated with failure risk. Factors predicting failure to respond to the AED were history of febrile seizure and type of BOEC in children with BOEC.

A study of epilepsy, according to the age at onset of the crisis and its causes, monitored by a Paediatric Neurology Unit over a period of three years. Historical cohorts study was conducted by reviewing the Paediatric Neurology medical records data base of epileptic children followed-up from 1 January 2008 to 31 December 2010. A total of 4,595 children were attended during the study period. The diagnosis of epilepsy was established in 605 (13.17%): 277 (45.79%) symptomatic, 156 (25.79%) idiopathic, and 172 (28.43%) with cryptogenic epilepsy. Absence epilepsy and benign childhood epilepsy with centro-temporal spikes are the idiopathic epileptic syndromes most prevalent, and the most prevalent symptomatic epilepsies are prenatal encephalopathies. More than one-quarter (26.12%) of epilepsies began in the first year of life, and 67.72% were symptomatic. Refractory epilepsy was observed in 25.29%, 42.46% with cognitive impairment, 26.45% with motor involvement, and 9.92% with an autism spectrum disorder, being more frequent at an earlier age of onset. The absence of a universally accepted classification of epileptic syndromes makes tasks like this difficult, starting with the terminology. A useful classification would be aetiological, with two groups: a large group with established aetiology, or very likely genetic syndromes, and another with no established cause. The age of onset of epilepsy in each aetiological group helps in the prognosis, which is worsened by refractoriness and associated neurodevelopmental disorders, and are generally worse at an earlier onset and in certain aetiologies.

To determine whether refractory epilepsy affects the health-related quality of life (HRQOL) of children with or without intellectual disability (ID), and if the presence of ID independently compromises HRQOL in children with refractory epilepsy. Subjects were parents of children with refractory epilepsy, whose syndrome had been defined using ILAE (International League Against Epilepsy) criteria and video-EEG monitoring. Children had the presence or absence of ID determined by formal neuropsychological or educational assessment. The relative effect of epilepsy on the two intellectual ability groups was determined using relevant clinical variables. Parents completed a valid epilepsy-specific HRQOL questionnaire for children, the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE), and, depending on intellectual ability level, the Child Behaviour Checklist or Developmental Behaviour Checklist. Both intellectually normal children with epilepsy and children with epilepsy and ID were more likely to have psychosocial problems compared with their respective intellectual ability reference populations. The results also revealed that children with ID had reduced HRQOL compared with intellectually normal children; a result independent of epilepsy. Analysis of the relationship between epilepsy variables and HRQOL revealed that the QOLCE was the most sensitive in detecting variation in age at onset, seizure frequency, and medications taken. The HRQOL of children with refractory epilepsy is greatly affected, regardless of intellectual ability level. The presence of ID in children with epilepsy independently depresses HRQOL outcomes. Compared with two generic HRQOL measures, the QOLCE was the most sensitive measure to variation in epilepsy variables.

Our prospective study aimed at the validation of EpiTrack Junior, a neuropsychological screening tool for attention and executive functions in children with epilepsy. Twenty-two children with absence epilepsy aged 8-17 years underwent comprehensive neuropsychological evaluation including EpiTrack Junior and measures of intelligence, verbal and nonverbal memory, word fluency and visuoconstructive organization. Concurrent and discriminant validity of EpiTrack Junior subtests and total score as well as sensitivity and specificity of the total score were analyzed. EpiTrack Junior total score was impaired in 59% of participants. Concurrent validity was demonstrated in 4/6 subtests and for the total score. Discriminant validity was shown with respect to verbal and nonverbal long-term memory. Sensitivity was higher than specificity and highest for the "working memory index". EpiTrack Junior is recommended as a sensitive and time-efficient screening tool for attention and executive functions in children with epilepsy. Impaired results should be followed up with detailed evaluation including information from the parents and school as well as counseling where indicated. © 2013.

Academic difficulties are common in children with epilepsy, although little is known about the effect of various seizure-related and cognitive variables. Given that persistent seizures may negatively impact academics, and that working memory is predictive of academic abilities, we examined the effects of recent seizures and working memory on word reading, spelling, and arithmetic in pediatric epilepsy. We hypothesized that persistent seizures would be associated with lower working memory ability, which would in turn result in poorer academic performance. Our sample consisted of 91 children with epilepsy being treated at the Hospital for Sick Children in Toronto, Canada, who underwent neuropsychological testing between 2002 and 2009 to help determine surgical candidacy. Four to 11 years later, follow-up testing was conducted on both surgical (n=61) and non-surgical (n=30) patients. Seizure status was defined by the presence or absence of seizures within the preceding 12 months. 5000 bias-corrected bootstrap resamples with replacement were used to calculate the 95% confidence intervals (CIs) for the indirect effect of seizure status on academics through working memory, controlling for baseline academic functioning. Persistent seizures were associated with reduced working memory, which was in turn associated with lower reading (B=-4.64, 95% CI [-10.21, -1.30]), spelling (B=-7.09, 95% CI [-13.97, -2.56], and arithmetic scores (B=-8.04, 95% CI [-13.66, -3.58] at follow-up. For children with intractable epilepsy, working memory deficits present a significant barrier to the development of academic skills. Working memory interventions may be a helpful adjunct to academic remediation in this population to facilitate academic progress. (JINS, 2017, 23, 594-604).

There is growing concern about the long-term neurologic effects of prenatal exposure to maternal overweight and obesity. The causes of epilepsy are poorly understood and, in more than 60% of the patients, no definitive cause can be determined. To investigate the association between early pregnancy body mass index (BMI) and the risk of childhood epilepsy and examine associations between obesity-related pregnancy and neonatal complications and risks of childhood epilepsy. A population-based cohort study of 1 441 623 live single births at 22 or more completed gestational weeks in Sweden from January 1, 1997, to December 31, 2011, was conducted. The diagnosis of epilepsy as well as obesity-related pregnancy and neonatal complications were based on information from the Sweden Medical Birth Register and National Patient Register. Multivariate Cox proportional hazards regression models were used to estimate adjusted hazard ratios (HRs) and 95% CIs after adjusting for maternal age, country of origin, educational level, cohabitation with partner, height, smoking, maternal epilepsy, and year of delivery. Data analysis was conducted from June 1 to December 15, 2016. Risk of childhood epilepsy. Of the 1 421 551 children born between January 1, 1997, and December 31, 2011, with covariate information available, 7592 (0.5%) were diagnosed with epilepsy through December 31, 2012. Of these 3530 (46.5%) were female. The overall incidence of epilepsy in children aged 28 days to 16 years was 6.79 per 10 000 child-years. Compared with offspring of normal-weight mothers (BMI 18.5 to epilepsy by maternal BMI categories were as follows: overweight (BMI 25.0 to epilepsy were considerably increased for children with malformations of the nervous system (adjusted HR, 46.4; 95% CI, 42.2-51.0), hypoxic ischemic encephalopathy (adjusted HR, 23.6; 95% CI, 20.6-27.1), and neonatal convulsions (adjusted HR, 33.5; 95% CI, 30.1-37.4).

The aim of this study was to develop and validate a brief version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). A secondary aim was to compare the results described in previously published studies using the QOLCE-55 with those obtained using the new brief version. Data come from 373 children involved in the Health-related Quality of Life in Children with Epilepsy Study, a multicenter prospective cohort study. Item response theory (IRT) methods were used to assess dimensionality and item properties and to guide the selection of items. Replication of results using the brief measure was conducted with multiple regression, multinomial regression, and latent mixture modeling techniques. IRT methods identified a bi-factor graded response model that best fits the data. Thirty-nine items were removed, resulting in a 16-item QOLCE (QOLCE-16) with an equal number of items in all 4 domains of functioning (Cognitive, Emotional, Social, and Physical). Model fit was excellent: Comparative Fit Index = 0.99; Tucker-Lewis Index = 0.99; root mean square error of approximation = 0.052 (90% confidence interval [CI] 0.041-0.064); weighted root mean square = 0.76. Results that were reported previously using the QOLCE-55 and QOLCE-76 were comparable to those generated using the QOLCE-16. The QOLCE-16 is a multidimensional measure of health-related quality of life (HRQoL) with good psychometric properties and a short-estimated completion time. It is notable that the items were calibrated using multidimensional IRT methods to create a measure that conforms to conventional definitions of HRQoL. The QOLCE-16 is an appropriate measure for both clinicians and researchers wanting to record HRQoL information in children with epilepsy.

Learning Disorders (LD) are defined as disorders that interfere with academic performance or with daily activities that require reading, writing or mathematical skills in subjects with a normal intelligence quotient (IQ). The prevalence of LD in the general population has been found to be 2-10%, and reading disorders are the most frequent subtype. Epilepsy is one of the most common serious neurological disorders in childhood. LD are more common in children with epilepsy than in the general population. As a consequence, the risk of cognitive impairment in children with epilepsy is high, and a review of the literature needs to be fully presented. Narrative review including articles regarding LD in children with various epileptic syndromes published in the international medical literature. LD are more frequent among children with epilepsy. The etiology is multifactorial, being affected by the type of epileptic syndrome, the age of onset and the antiepileptic treatment being selected. LD can be either permanent or state-dependent. Each category has different treatment protocols and prognosis. Despite the fact that the findings of the studies discussed in our article support the evidence that epilepsy in childhood impairs the cognitive function, we should not underestimate the role of demographic and psychosocial factors on academic performance of children with epilepsy. Despite the high prevalence of LD, a healthy family and school environment can help reduce its impact on the patient's quality of life. © Springer-Verlag 2010

Musical and poetic creativity and epilepsy.

Science.gov (United States)

Hesdorffer, Dale C; Trimble, Michael

2016-04-01

Associations between epilepsy and musical or poetic composition have received little attention. We reviewed the literature on links between poetic and musical skills and epilepsy, limiting this to the Western canon. While several composers were said to have had epilepsy, John Hughes concluded that none of the major classical composers thought to have had epilepsy actually had it. The only composer with epilepsy that we could find was the contemporary composer, Hikari Oe, who has autism and developed epilepsy at age 15years. In his childhood years, his mother found that he had an ability to identify bird sound and keys of songs and began teaching him piano. Hikari is able to compose in his head when his seizures are not severe, but when his seizures worsen, his creativity is lost. Music critics have commented on the simplicity of his musical composition and its monotonous sound. Our failure to find evidence of musical composers with epilepsy finds parallels with poetry where there are virtually no established poets with epilepsy. Those with seizures include Lord George Byron in the setting of terminal illness, Algernon Swinburne who had alcohol-related seizures, Charles Lloyd who had seizures and psychosis, Edward Lear who had childhood onset seizures, and Vachel Lindsay. The possibility that Emily Dickinson had epilepsy is also discussed. It has not been possible to identify great talents with epilepsy who excel in poetic or musical composition. There are few published poets with epilepsy and no great composers. Why is this? Similarities between music and poetry include meter, tone, stress, rhythm, and form, and much poetry is sung with music. It is likely that great musical and poetic compositions demand a greater degree of concentration and memory than is possible in epilepsy, resulting in problems retaining a musical and mathematical structure over time. The lack of association between recognizable neuropsychiatric disorders and these skills is a gateway to

As opposed to focal epilepsy, absence seizures do not exhibit a clear seizure onset zone or focus since its ictal activity rapidly engages both brain hemispheres. Yet recent graph theoretical analysis applied to absence seizures EEG suggests the cortical focal presence, an unexpected feature for this type of epilepsy. In this study, we explore the characteristics of absence seizure by classifying the nodes as to their source/sink natures via weighted directed graph analysis based on connectivity direction and strength estimation using information partial directed coherence (iPDC). By segmenting the EEG signals into relatively short 5-sec-long time windows we studied the evolution of coupling strengths from both sink and source nodes, and the network dynamics of absence seizures in eight patients.

Absence epilepsy is a neurological disorder that causes a recurrent loss of consciousness and generalized spike-and-wave discharges on an electroencephalogram (EEG). The role of metabotropic glutamate receptors (mGluRs) and associated scaffolding proteins in absence epilepsy has been unclear to date. We investigated a possible role for these proteins in absence epilepsy, focusing on the mGluR7a receptor and its PDZ-interacting protein, protein interacting with C kinase 1 (PICK1), in rats and ...

Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. Prospective cohort study conducted between March 1, 2007, and January 1, 2012. Three tertiary care pediatric hospitals. Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal (≥37 weeks' gestation to 28 days) and 53 childhood subjects (>28 days to Acute symptomatic seizures (clinically evident and electrographic-only seizures within 7 days), remote symptomatic seizures, and epilepsy. Acute symptomatic seizures occurred in 35 subjects (48%). Acute symptomatic seizures as a presenting symptom of ICH occurred in 12 perinatal (60%) and 19 childhood (36%) subjects (P = .07). Acute symptomatic seizures after presentation occurred in 7 children. Electrographic-only seizures were present in 9 of 32 subjects (28%) with continuous electroencephalogram monitoring. One-year and 2-year remote symptomatic seizure-free survival rates were 82% (95% CI, 68-90) and 67% (95% CI, 46-82), respectively. One-year and 2-year epilepsy-free survival rates were 96% (95% CI, 83-99) and 87% (95% CI, 65-95), respectively. Elevated intracranial pressure requiring acute intervention was a risk factor for seizures after presentation (P = .01; Fisher exact test), remote symptomatic seizures, and epilepsy (P = .03, and P = .04, respectively; log-rank test). Presenting seizures are common in perinatal and childhood ICH. Continuous

is without a doubt one of the most ancient and enigmatic conditions in the history of medicine, as it was already described in remote times. From the ancestral obscure understanding of epilepsy to the present, there have been important scientific advances in the knowledge of its diagnosis and treatment. The management of a child with epilepsy requires following a protocol that includes a detailed clinical and laboratory evaluation. All chronic diseases, and also epilepsy, are felt as a double aggression: 1 Internal, related to the changes that the disease causes, and 2 external, related to the tests, medications, excessive protection, and all the rules and prohibitions that are applied. The doctor (pediatrician, pediatric neurologist or epileptologist, when initiating a relationship with the child with epilepsy, is going to propose "a new code", often hard to accept. He is going to intervene far away from the crisis, or soon after it happened, in an environment characterized by significant anguish for the family. There is no question that the disease is difficult for the child, as it is also for the parents, who become responsible for a different type of care, are preoccupied daily about their son taking the medication regularly, and suffer awaiting for another crisis to happen. Epilepsy, more than other conditions, creates a high level of restlessness because of the spectacular, dramatic nature of its presentation and for the ancestral myths still attributed to it. For all these reasons, the diagnosis of epilepsy is frequently accompanied by three relevant reactions in the family: anxiety, guilt and aggressiveness. The intervention of the doctor in the treatment of childhood epilepsy must be "global". With mystic devotion, the doctor must embrace the true Hippocratic concept of patient care.

To investigate the clinical and neurophysiological characteristics, particularly therapeutic considerations, of epileptic negative myoclonus (ENM) in atypical benign partial epilepsy (ABPE) of childhood. From 1998 to 2006, 14/242 patients with benign children epilepsy with centrotemporal spikes (BECTS) were diagnosed as having ABPE with ENM. In all 14 patients, we performed video-EEG monitoring along with tests with the patient's arms outstretched; 6/14 patients were also simultaneously underwent surface electromyogram (EMG). ENM manifestations, electrophysiological features, and responses to antiepileptic drugs were analyzed. In all cases, ENM developed after the onset of epilepsy and during antiepileptic drug therapy, and the appearance of ENM were corresponding to EEG findings of high-amplitude spikes followed by a slow wave in the contralateral motor areas with secondary generalization. This was further confirmed by time-locked silent EMG. During ENM occurrence or recurrence, habitual seizures and interictal discharges were exaggerated. In some patients, the changes in antiepileptic drug regimens in relation to ENM appearance included add-on therapy with carbamazepine, oxcarbazepine, and phenobarbital or withdrawal of valproate. ENM was controlled in most cases by administration of various combinations of valproate, clonazepam, and corticosteroids. The incidence of ENM or ABPE in our center was approximately 5.79%. A combination of video-EEG monitoring with the patient's arms outstretched and EMG is essential to identify ENM. The aggravation of habitual seizures and interictal discharges indicate ENM. Some antiepileptic drugs, such as carbamazepine, oxcarbazepine, and phenobarbital, may be related to ENM occurrence during spontaneous aggravation of ABPE. Various combinations of valproate, benzodiazepines, and corticosteroids are relatively effective for treating ENM that occurs in ABPE.

Full Text Available Background: The early and late benign occipital epilepsies of childhood (BOEC are described as two discrete electro-clinical syndromes, eponymously known as Panayiotopoulos and Gastaut syndromes. The purpose of this study was to identify predictors of failure to respond to the initial antiepileptic drug (AED. Materials and Methods: A total of 42 children with BOEC were enrolled. Predictive factors were analyzed by survival methods. Results: Among the 42, 25 patients (59.5% were boys and 17 (40.5% were girls and the mean age at the seizure onset was 7.46 ± 2.65 years (4-14 years. Of the 42 patients, 34 (81.0% were treated relatively successfully with the first AED treatment, and 8 (19.0% were not responded initial AED treatment. There was no correlation between response to initial AED treatment and sex, consanguinity, epilepsy history of family, age of seizure onset, frequency of seizures, history of status epilepticus, duration of starting first treatment, findings on electroencephalogram. However, history of febrile seizure and type of BOEC were significantly associated with failure risk. Conclusions: Factors predicting failure to respond to the AED were history of febrile seizure and type of BOEC in children with BOEC.

Recent clinical trials indicate that cannabidiol (CBD) may reduce seizure frequency in pediatric patients with certain forms of treatment-resistant epilepsy. Many of these patients experience significant impairments in quality of life (QOL) in physical, mental, and social dimensions of health. In this study, we measured the caregiver-reported Quality of Life in Childhood Epilepsy (QOLCE) in a subset of patients enrolled in a prospective, open-label clinical study of CBD. Results from caregivers of 48 patients indicated an 8.2 ± 9.9-point improvement in overall patient QOLCE (p < 0.001) following 12 weeks of CBD. Subscores with improvement included energy/fatigue, memory, control/helplessness, other cognitive functions, social interactions, behavior, and global QOL. These differences were not correlated to changes in seizure frequency or adverse events. The results suggest that CBD may have beneficial effects on patient QOL, distinct from its seizure-reducing effects; however, further studies in placebo-controlled, double-blind trials are necessary to confirm this finding.

Reports of childhood epilepsies in temporal association with vaccination have had a great impact on the acceptance of vaccination programs by health care providers, but little is known about this possible temporal association and about the types of seizures following vaccinations. For these reasons the Italian League Against Epilepsy (LICE), in collaboration with other Italian scientific societies, has decided to generate Guidelines on Vaccinations and Epilepsy. The aim of Guidelines on Vaccinations and Epilepsy is to present recent unequivocal evidence from published reports on the possible relationship between vaccines and epilepsy in order to provide information about contraindications and risks of vaccinations in patients with epilepsy. The following main issues have been addressed: (1) whether contraindications to vaccinations exist in patients with febrile convulsions, epilepsy, and/or epileptic encephalopathies; and (2) whether any vaccinations can cause febrile seizures, epilepsy, and/or epileptic encephalopathies. Diphtheria-tetanus-pertussis (DTP) vaccination and measles, mumps, and rubella vaccination (MMR) increase significantly the risk of febrile seizures. Recent observations and data about the relationships between vaccination and epileptic encephalopathy show that some cases of apparent vaccine-induced encephalopathy could in fact be caused by an inherent genetic defect with no causal relationship with vaccination.

Children with benign epilepsy with centrotemporal spikes (BECTS) have traditionally been considered to have a uniformly good prognosis. However, benign may be a misnomer because BECTS is linked to cognitive deficits, a more severe phenotype with intractable seizures, and the potential for sudden unexpected death in epilepsy (SUDEP). To determine if cases of BECTS are present in the North American SUDEP Registry (NASR). The NASR is a clinical and biospecimen repository established in 2011 to promote SUDEP research. The NASR database, which includes medical records, results of electroencephalographic tests, and interviews with family members of patients with epilepsy who died suddenly without other identifiable causes of death, was queried from June 3, 2011, to June 3, 2016, for cases of BECTS. The patients with epilepsy had died suddenly without other identifiable causes of death (eg, drowning, trauma, exposure to toxic substances, or suicide); SUDEP classification was determined by the consensus of 2 epileptologists. Cases of SUDEP among children who received a diagnosis of BECTS among patients reported in the NASR. Three boys (median age at death, 12 years; range, 9-13 years) who received a diagnosis of BECTS by their pediatric epileptologist or neurologists were identified among 189 cases reported in the NASR. The median age of epilepsy onset was 5 years (range, 3-11 years), and the median duration of epilepsy was 4 years (range, 1-10 years). Two deaths were definite SUDEP, and 1 was probable SUDEP. Independent review of clinical and electroencephalographic data supported the diagnosis of BECTS in all 3 patients. None of the patients was prescribed antiseizure drugs, either owing to physician recommendation or mutual decision by the physician and parents. All 3 patients were found dead in circumstances typical of SUDEP. The 3 patients spanned the spectrum of BECTS severity: 1 had only a few seizures, 1 had more than 30 focal motor seizures, and 1 had 4 witnessed

Benign epilepsy of childhood with centrotemporal spikes (BECTS) is the most frequent focal epilepsy in children; however, the pattern of affected memory processes remains controversial. Previous studies in BECTS imply deficits in complex working memory tasks, but not in simple modality-specific tasks. We studied working memory processes in children with BECTS by comparing performance in memory binding tasks of different complexities. We compared 17 children with BECTS (aged 6 to 13 years) to 17 healthy children matched for age, sex, and intelligence quotient. We measured spatial and verbal memory components separately and jointly on three single-binding tasks (binding of what and where; what and when; and where and when) and a combined-binding task (integration of what, where, and when). We also evaluated basic visuospatial memory functions with subtests of the Children's Memory Scale, and intellectual abilities with verbal tasks of the Wechsler Intelligence Scale for Children-Fourth Edition and the Raven Progressive Matrices. We found no difference between the BECTS and control groups in single-binding tasks; however, the children with BECTS performed significantly worse on the combined task, which included integration of spatial, verbal, and temporal information. We found no deficits in their intellectual abilities or basic visuospatial memory functions. Children with BECTS may have intact simple maintenance processes of working memory, but difficulty with high-level functions requiring attentional and executive resources. Our findings imply no specific memory dysfunction in BECTS, but suggest difficulties in integrating information within working memory, and possible frontal lobe disturbances.

Purpose To determine the incidence and classification of new-onset epilepsy, as well as the distribution of epilepsy syndromes in a population-based group of children, using the newly proposed Report of the ILAE Commission on Classification and Terminology 2005–2009. Methods We identified all children residing in Olmsted County, MN, 1 month through 17 years with newly diagnosed epilepsy from 1980–2004. For each patient, epilepsy was classified into mode of onset, etiology, and syndrome or constellation (if present). Incidence rates were calculated overall and also separately for categories of mode of onset and etiology. Results The adjusted incidence rate of new-onset epilepsy in children was 44.5 cases per 100,000 persons per year. Incidence rates were highest in the first year of life and diminished with age. Mode of onset was focal in 68%, generalized/bilateral in 23%, spasms in 3% and unknown in 5%. Approximately half of children had an unknown etiology for their epilepsy, and of the remainder, 78 (22%) were genetic and 101 (28%) were structural/metabolic. A specific epilepsy syndrome could be defined at initial diagnosis in 99/359 (28%) children, but only 9/359 (3%) had a defined constellation. Conclusion Nearly half of childhood epilepsy is of “unknown” etiology. While a small proportion of this group met criteria for a known epilepsy syndrome, 41% of all childhood epilepsy is of “unknown” cause with no clear syndrome identified. Further work is needed to define more specific etiologies for this group. PMID:21482075

Epilepsy is the tendency to have unprovoked epileptic seizures. Anything causing structural or functional derangement of brain physiology may lead to seizures, and different conditions may express themselves solely by recurrent seizures and thus be labelled “epilepsy.” Worldwide, epilepsy is the most common serious neurological condition. The range of risk factors for the development of epilepsy varies with age and geographic location. Congenital, developmental and genetic conditions are mostly associated with the development of epilepsy in childhood, adolescence and early adulthood. Head trauma, infections of the central nervous system (CNS) and tumours may occur at any age and may lead to the development of epilepsy. Infections of the CNS are a major risk factor for epilepsy. The reported risk of unprovoked seizures in population-based cohorts of survivors of CNS infections from developed countries is between 6.8 and 8.3 %, and is much higher in resource-poor countries. In this review, the various viral, bacterial, fungal and parasitic infectious diseases of the CNS which result in seizures and epilepsy are discussed. The pathogenesis of epilepsy due to brain infections, as well as the role of experimental models to study mechanisms of epileptogenesis induced by infectious agents, is reviewed. The sterile (non-infectious) inflammatory response that occurs following brain insults is also discussed, as well as its overlap with inflammation due to infections, and the potential role in epileptogenesis. Furthermore, autoimmune encephalitis as a cause of seizures is reviewed. Potential strategies to prevent epilepsy resulting from brain infections and non-infectious inflammation are also considered.

The aim of this study was to identify the different influencing patterns of demographic and epilepsy-related variables on various aspects of psychosocial function in pediatric epilepsy. Five hundred ninety-eight patients with pediatric epilepsy between the ages of 4 and 18 years (boys=360, 60% and girls=238, 40%) and their parents participated in the study. Parents completed the Social Maturity Scale (SMS), the Korean version of the Child Behavior Checklist (K-CBCL), and the Korean version of the Quality of Life in Childhood Epilepsy Questionnaire (K-QOLCE) to assess daily living function, behavior, and quality of life. The Children's Global Assessment Scale (CGAS) was completed by clinicians to assess general adaptive function. Demographic variables, such as age and sex of child, and epilepsy-related clinical variables, including seizure type, seizure frequency, duration of epilepsy, and number of medications, were obtained from medical records. Demographic and epilepsy-related clinical variables had a strong influence (22-32%) on the cognition-related domain such as general adaptive function, school/total competence, and quality of life for cognitive function while a comparatively smaller effect (2-16%) on the more psychological domain including behavioral, emotional, and social variables. Younger age, shorter duration of illness, and smaller number of medications showed a strong positive impact on psychosocial function in pediatric epilepsy, particularly for adaptive function, competence, and quality-of-life aspects. Given the wide range of impact of demographic and clinical variables on various facets of psychosocial functions, more specific understanding of the various aspects of factors and their particular pattern of influence may enable more effective therapeutic approaches that address both the medical and psychological needs in pediatric epilepsy.

Typical childhood development is characterized by the emergence of intrinsic connectivity networks (ICNs) by way of internetwork segregation and intranetwork integration. The impact of childhood epilepsy on the maturation of ICNs is, however, poorly understood. The developmental trajectory of ICNs in 26 children (8-17 years) with localization-related epilepsy and 28 propensity-score matched controls was evaluated using graph theoretical analysis of whole brain connectomes from resting-state functional magnetic resonance imaging (fMRI) data. Children with epilepsy demonstrated impaired development of regional hubs in nodes of the salience and default mode networks (DMN). Seed-based connectivity and hierarchical clustering analysis revealed significantly decreased intranetwork connections, and greater internetwork connectivity in children with epilepsy compared to controls. Significant interactions were identified between epilepsy duration and the expected developmental trajectory of ICNs, indicating that prolonged epilepsy may cause progressive alternations in large-scale networks throughout childhood. DMN integration was also associated with better working memory, whereas internetwork segregation was associated with higher full-scale intelligence quotient scores. Furthermore, subgroup analyses revealed the thalamus, hippocampus, and caudate were weaker hubs in children with secondarily generalized seizures, relative to other patient subgroups. Our findings underscore that epilepsy interferes with the developmental trajectory of brain networks underlying cognition, providing evidence supporting the early treatment of affected children.

Full Text Available Objective. Herbal medicine has been widely used to treat drug resistant epilepsy. Shihogyejitang (SGT has been commonly used to treat epilepsy. We investigated the effect and safety of SGT in children with drug resistant epilepsy. Design. We reviewed medical records of 54 patients with epilepsy, who failed to respond to at least two antiepileptic drugs and have been treated with SGT between April 2006 and June 2014 at the Department of Pediatric Neurology, I-Tomato Hospital, Korea. Effect was measured by the response rate, seizure-free rate, and retention rate at six months. We also checked adverse events, change in antiepileptic drugs use, and the variables related to the outcome. Results. Intent-to-treat analysis showed that, after six months, 44.4% showed a >50% seizure reduction, 24.1% including seizure-free, respectively, and 53.7% remained on SGT. Two adverse events were reported, mild skin rash and fever. Focal seizure type presented significantly more positive responses when compared with other seizure types at six months (p=0.0284, Fisher’s exact test. Conclusion. SGT is an effective treatment with excellent tolerability for drug resistant epilepsy patients. Our data provide evidence that SGT may be used as alternative treatment option when antiepileptic drug does not work in epilepsy children.

To develop and validate a shortened version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). A secondary aim was to compare baseline risk factors predicting health-related quality of life (HRQoL) in children newly diagnosed with epilepsy, as identified using the original and shortened version. Data came from the Health-Related Quality of Life in Children with Epilepsy Study (HERQULES, N = 373), a multicenter prospective cohort study. Principal component analysis reduced the number of items from the original QOLCE, and factor analysis was used to assess the factor structure of the shortened version. Convergent and divergent validity was assessed by correlating the Child Health Questionnaire (CHQ) with the shortened QOLCE. Multiple regression identified risk factors at diagnosis for HRQoL at 24 months. A four-factor, higher-order, 55-item solution was obtained. A total of 21 items were removed. The final model represents functioning in four dimensions of HRQoL: Cognitive, Emotional, Social, and Physical. The shortened QOLCE demonstrated acceptable fit: Bentler's Comparative Fit Index = 0.944; Tucker-Lewis Index = 0.942; root mean square approximation = 0.058 (90% CI: 0.056-0.061); weighted root mean square residuals (WRMR) = 1.582, and excellent internal consistency (α = 0.96, subscales α > 0.80). Factor loadings were good (first-order: λ = 0.66-0.93; higher-order λ = 0.66-0.85; p QOLCE scores correlated strongly with similar subscales of the Child Health Questionnaire (ρ = 0.38-0.70) while correlating weakly with dissimilar subscales (ρ = 0.30-0.31). While controlling for HRQoL at diagnosis, predictors for better HRQoL at 24 months were the following: no cognitive problems reported (p = 0.001), better family functioning (p = 0.014), fewer family demands (p = 0.008), with an interaction between baseline HRQoL and cognitive problems (p = 0.011). Results offer initial evidence regarding reliability and validity of the proposed 55-item shortened

To explore the influence of several estimates of family socioeconomic status on the long-term clinical course and social outcomes of children with epilepsy. The Nova Scotia childhood epilepsy cohort is population based and includes all children in this Canadian province who developed epilepsy between 1977 and 1985. Eligible patients had ≥10 years of follow-up. Children with childhood absence epilepsy were excluded. Total family income at seizure onset was assessed at seizure onset and classified as "poor" (first quintile), "adequate" (second to third quintiles), and "well-off" (fourth to fifth quintiles). We also assessed parental education and home ownership. Social outcome was assessed in those with normal intelligence who were ≥18 years of age at the end of follow-up using a semistructured interview that explored eight adverse effects. Of 584 patients, 421 (72%) were included. Average follow-up was 26 ± 5.6 years. Overall 137 families (33%) had "poor" income, 159 (38%) had "adequate income," and 125 (30%) were "well-off." Terminal remission of epilepsy occurred in 65% of the poor, 61% of the adequate, and 61% of the well-off (p = ns). Intractable epilepsy, status epilepticus, number of antiepileptic drugs (AEDs) used, and the number of generalized tonic-clonic or focal with secondary generalization seizures through the clinical course was the same in all groups. Home ownership did not predict remission. Neither paternal nor maternal education was associated with remission. Poor children had significantly more adverse social outcomes including failure to graduate from high school, unemployment, personal poverty, inadvertent pregnancy, and psychiatric diagnoses. In Nova Scotia with universal health care, coming from a poor or more affluent family does not seem to affect the clinical course or long-term seizure outcome of childhood epilepsy. Unfortunately children from poor families are less likely to have a good social outcome. Wiley Periodicals, Inc

Permanent freedom from fits can be achieved in a large proportion of children with a history of epilepsy through precise individual adjustment and careful maintenance of the therapeutic regimen. A review of the cases treated at the Pediatric Clinic, out-Patient-Department for Epileptics, University of Vienna, reveals that at present about 70% of the patients have a good prognosis (the figures vary from 50 to 85%, depending on the seizure type). An important question which has received only scant attention in the literature arises in the case of patients who have remained free from epileptic fits over a period of many years, namely whether longterm antiepileptic therapy can be terminated and, if so, then when and how. Only very few studies deal specifically with this problem and even these do not provide entirely satisfactory answers to all the posed questions, not only with regard to the optimum time and mode of drug reduction, but also with regard to the principles underlying the choice of apparently suitable candidates for attempted termination of therapy. An attempt is made in this retrospective study comprising 375 patients who have been followed up over a period of at least 5 years, to throw some light on these problems. Indeed, results of statistical significance were obtained by the use of a new mathematical technique, which enables the formulation of new guiding principles in the resolution of all three above-mentioned questions. In consequence, it now appears within the power of the pediatrician to markedly reduce the risk of relapse, which in the case of childhood epilepsies, is about 20%, at present. In general, several basic principles must be adhered to. Total freedom from convulsions over an uninterrupted period of at least 3 years' duration is an absolute prerequisite for consideration of cessation of therapy. Reduction in antiepileptic drug dosage should be carried out as a stepwise procedure over a period of about 2 years. Regular clinical and EEG

Common comorbidity of epilepsy: a review of new progress

2012-10-01

Full Text Available A range of medical and neurologic disorders occurs more frequently in people with epilepsy than in the general population and constitutes somatic comorbidity. Common examples include migraine, depression, schizophrenia, attention-deficit hyperactivity disorder (ADHD, sleep disorder, cognitive damage, developmental abnormality and so on. There are more interesting clinical features in some special types of patients with benign epilepsy of childhood with centrotemporal spikes (BECT, temporal epilepsy and mitochondrial encephalomyopathy. The association between epilepsy and other conditions can be due to a variety of interacting genetic, biologic structural, functional, pharmacological and environmental factors. Co-existence of other disorders in a person with epilepsy can complicate diagnosis, induce adverse prognostic implications and attenuate health?related quality of life. Therefore, recognition and management of comorbidity of epilepsy may facilitate the treatment of epilepsy. In this article, we review recent pathophysiologic and clinical studies to elucidate the etiology, mechanisms, clinical characteristics, differential diagnosis and treatment of common comorbidity of epilepsy.

The incidence and prevalence of adults diagnosed with epilepsy is higher compared to those diagnosed in childhood, yet the experience of living with adult-onset epilepsy has rarely been examined. Hence, the current study took a phenomenological approach to examining the experience of living with epilepsy following diagnosis in adulthood. Semi-structured interviews were conducted with 39 people from across the UK, diagnosed with epilepsy between the ages of eighteen and sixty, at two points in time, six months apart. Phenomenological analysis identified three central themes: the unpredictability of seizure occurrence; the ripple effect; and re-evaluating the future. Despite the accepted consensus in the epilepsy literature that living and coping with epilepsy becomes more difficult the older a person is diagnosed, the current findings indicated that this is inadequate. Rather, it is more suitable to consider that those living with adult-onset epilepsy have a specific experience of the condition and particular support needs, given that they once lived their lives as people without epilepsy.

Genetic mechanisms explain the pathophysiology of many forms of epilepsy and other paroxysmal disorders such as alternating hemiplegia of childhood, familial hemiplegic migraine, and paroxysmal dyskinesias. Epilepsy is a key feature of well-defined genetic syndromes including Tuberous Sclerosis Complex, Rett syndrome, Angelman syndrome, and others. There is an increasing number of singe gene causes or susceptibility factors associated with several epilepsy syndromes, including the early onset epileptic encephalopathies, benign neonatal/infantile seizures, progressive myoclonus epilepsies, genetic generalized and benign focal epilepsies, epileptic aphasias, and familial focal epilepsies. Molecular mechanisms are diverse, and a single gene can be associated with a broad range of phenotypes. Additional features, such as dysmorphisms, head size, movement disorders, and family history may provide clues to a genetic diagnosis. Genetic testing can impact medical care and counseling. We discuss genetic mechanisms of epilepsy and other paroxysmal disorders, tools and indications for genetic testing, known genotype-phenotype associations, the importance of genetic counseling, and a look towards the future of epilepsy genetics.

Sleep and Epilepsy: Strange Bedfellows No More.

2011-09-01

Ancient philosophers and theologians believed that altered consciousness freed the mind to prophesy the future, equating sleep with seizures. Only recently has the bidirectional influences of epilepsy and sleep upon one another received more substantive analysis. This article reviews the complex and increasingly recognized interrelationships between sleep and epilepsy. NREM sleep differentially activates interictal epileptiform discharges during slow wave (N3) sleep, while ictal seizure events occur more frequently during light NREM stages N1 and N2. The most commonly encountered types of sleep-related epilepsies (those with preferential occurrence during sleep or following arousal) include frontal and temporal lobe partial epilepsies in adults, and benign epilepsy of childhood with centrotemporal spikes (benign rolandic epilepsy) and juvenile myoclonic epilepsy in children and adolescents. Comorbid sleep disorders are frequent in patients with epilepsy, particularly obstructive sleep apnea in refractory epilepsy patients which may aggravate seizure burden, while treatment with nasal continuous positive airway pressure often improves seizure frequency. Distinguishing nocturnal events such as NREM parasomnias (confusional arousals, sleep walking, and night terrors), REM parasomnias including REM sleep behavior disorder, and nocturnal seizures if frequently difficult and benefits from careful history taking and video-EEG-polysomnography in selected cases. Differentiating nocturnal seizures from primary sleep disorders is essential for determining appropriate therapy, and recognizing co-existent sleep disorders in patients with epilepsy may improve their seizure burden and quality of life.

Ideal epilepsy surgery would eliminate seizures without causing any functional deficits. The aim of the present study was to assess seizure outcomes and complications after epilepsy surgery in children with intractable epilepsy. Data obtained in 134 children (75 boys and 59 girls) age 17 years or younger who underwent epilepsy surgery at Seoul National University Children's Hospital between 1993 and 2005 were retrospectively reviewed. Epilepsy surgery included temporal resection (59 cases), extratemporal resection (56 cases), functional hemispherectomy (7 cases), callosotomy (9 cases), multiple subpial transection (1 case), and disconnection of a hamartoma (2 cases). The mean follow-up duration was 62.3 months (range 12-168 months). The overall seizure-free rate was 69% (93 of 134 cases). The seizure-free rate was significantly higher in children who underwent temporal resection than in those in whom extratemporal resection was performed (88 vs 55%, p surgery is an effective and safe therapeutic modality in childhood. In children with extratemporal epilepsy, more careful interpretation of clinical and investigative data is needed to achieve favorable seizure outcome.

Full Text Available The childhood epilepsy is a chronic disease that can have an impact in various spheres of life of the child, including academic performance and school attendance. This study aimed to describe and compare the school attendance of children with epilepsy who attend mainstream and special schools. Participants were 56 children aged between 7 and 14 years who attended regular or special schools located in two Brazilian cities of medium size. To collect the information we used two instruments: Data sheet of identification and characterization of the child and Data sheet to record the attendance school. The results showed that children in special schools had higher rates of absenteeism compared to students in regular schools. Additionally, we observed that these children use more drugs and have implications on health more severe than children in regular schools. Thus, it is the childhood epilepsy as a disease complex that brings substantial effects on various areas of children’s lives by reinforcing the need for studies that might expand the knowledge to and the experiences associated with the education of these children.

Electroencephalographic precursors of spike-wave discharges in a genetic rat model of absence epilepsy: Power spectrum and coherence EEG analyses.

Sitnikova, Evgenia; van Luijtelaar, Gilles

2009-04-01

Periods in the electroencephalogram (EEG) that immediately precede the onset of spontaneous spike-wave discharges (SWD) were examined in WAG/Rij rat model of absence epilepsy. Precursors of SWD (preSWD) were classified based on the distribution of EEG power in delta-theta-alpha frequency bands as measured in the frontal cortex. In 95% of preSWD, an elevation of EEG power was detected in delta band (1-4Hz). 73% of preSWD showed high power in theta frequencies (4.5-8Hz); these preSWD might correspond to 5-9Hz oscillations that were found in GAERS before SWD onset [Pinault, D., Vergnes, M., Marescaux, C., 2001. Medium-voltage 5-9Hz oscillations give rise to spike-and-wave discharges in a genetic model of absence epilepsy: in vivo dual extracellular recording of thalamic relay and reticular neurons. Neuroscience 105, 181-201], however, theta component of preSWD in our WAG/Rij rats was not shaped into a single rhythm. It is concluded that a coalescence of delta and theta in the cortex is favorable for the occurrence of SWD. The onset of SWD was associated with strengthening of intracortical and thalamo-cortical coherence in 9.5-14Hz and in double beta frequencies. No features of EEG coherence can be considered as unique for any of preSWD subtype. Reticular and ventroposteromedial thalamic nuclei were strongly coupled even before the onset of SWD. All this suggests that SWD derive from an intermixed delta-theta EEG background; seizure onset associates with reinforcement of intracortical and cortico-thalamic associations.

2017-05-01

Death in children with epilepsy is profoundly disturbing, with lasting effects on the family, community, and health care providers. The overall risk of death for children with epilepsy is about ten times that of the general population. However, the risk of premature death for children without associated neurological comorbidities is similar to that of the general population, and most deaths are related to the cause of the epilepsy or associated neurological disability, not seizures. The most common cause of seizure-related death in children with epilepsy is sudden unexpected death in epilepsy (SUDEP). SUDEP is relatively uncommon in childhood, but the risk increases if epilepsy persists into adulthood. Although the direct cause of SUDEP remains unknown, most often death follows a generalized convulsive seizure and the risk of SUDEP is strongly related to drug-resistant epilepsy and frequent generalized tonic-clonic seizures. The most effective SUDEP prevention strategy is to reduce the frequency of seizures, although a number of seizure detection devices are under development and in the future may prove to be useful for seizure detection for those at particularly high risk. There are distinct benefits for health care professionals to discuss mortality with the family soon after the diagnosis of epilepsy. An individual approach is appropriate. When a child with epilepsy dies, particularly if the death was unexpected, family grief may be profound. Physicians and other health care professionals have a critical role in supporting families that lose a child to epilepsy. This review will provide health care providers with information needed to discuss the risk of death in children with epilepsy and support families following a loss. Copyright © 2017 Elsevier Inc.

Patients with epilepsy, including children, have an increased mortality rate when compared to the general population. Only few studies on causes of mortality in childhood epilepsy exist and pediatric SUDEP rate is under continuous discussion. To describe general mortality, incidence of sudden unexpected death in epilepsy (SUDEP), causes of death and age distribution in a pediatric epilepsy patient population. The study retrospectively examined the mortality and causes of death in 1974 patients with childhood-onset epilepsy at a tertiary epilepsy center in Denmark over a period of 9 years. Cases of death were identified through their unique civil registration number. Information from death certificates, autopsy reports and medical notes were collected. 2.2% (n = 43) of the patient cohort died during the study period. This includes 9 patients with SUDEP (8 SUDEP cases per 10,000 patient years). 9 patients died in the course of neurodegenerative disease and 28 children died of various causes. Epilepsy was considered drug resistant in more than 95% of the deceased patients, 90% were diagnosed with intellectual disability. Mortality of patients that underwent dietary epilepsy treatment was slightly higher than in the general cohort. There were no epilepsy-related deaths due to drowning. This study confirms that SUDEP must not be disregarded in the pediatric age group. The vast majority of SUDEP cases in this study displays numerous risk factors similar to those described in adult epilepsy patients. Including SUDEP, only 30% of the mortality was directly seizure related. Copyright © 2013 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

Few studies have utilized both categorical and dimensional measures of psychopathology in children with epilepsy. We evaluated 173 children (88 males, 85 females; mean age 11.7y [SD 1.8]; range 9-14y) who had epilepsy (generalized 36%, partial 61%) for at least 6 months. The primary caregiver completed a dimensional measure, the Child Behavior…

Impairments in executive skills broadly span across multiple childhood epilepsy syndromes and can adversely affect quality of life. Bilingualism has been previously shown to correlate with enhanced executive functioning in healthy individuals. This study seeks to determine whether the bilingual advantage in executive functioning exists in the context of pediatric epilepsy. We retrospectively analyzed neuropsychological data in 52 children with epilepsy and compared executive function scores in monolingual versus bilingual children with epilepsy, while controlling for socioeconomic status and ethnicity. Bilingual children performed significantly better on the Working Memory scale than did monolingual children. There were no significant differences on the remaining executive function variables. The bilingual advantage appears to persist for working memory in children with epilepsy. These findings suggest that bilingualism is potentially a protective variable in the face of epilepsy-related working memory dysfunction. PMID:26720703

It has been theorized that conversion disorder is the result of emotion that cannot be experienced consciously as feeling states or put into words (i.e., alexithymia), but there is little confirming empirical evidence. We sought to characterize subjects with conversion disorder compared to subjects with a distinct medical illness, using the model of psychogenic non-epileptic seizures (PNES) vs. epilepsy (ES), on measures of childhood traumatic experience, alexithymia and maturity of psychological defensive strategies. All subjects admitted to the Epilepsy Monitoring Unit of the University of Cincinnati Medical Center were offered self-report questionnaires (Childhood Trauma Questionnaire, Toronto Alexithymia Scale-20 and Response Evaluation Measure-71) at the outset of evaluation. Diagnosis of each subject was confirmed by video-EEG and we compared subjects with PNES to those with ES on these measures. 82 subjects had ES AND 96 had PNES. Those with PNES were significantly more likely to have experienced childhood trauma in all domains (p=.005 to p=.05), and were significantly more likely to have alexithymia (p=.0267). There was a significant difference in the capacity to identify feelings, and a trend towards significance in capacity to describe feelings. There were no differences in defensive styles between the two groups. PNES diagnosis was associated with female sex, higher alexithymia scores and higher rates of childhood trauma, but not with differences in defensive styles compared to ES. These findings add empirical evidence for theories regarding the cause of conversion disorder and may aid in the design of prospective treatment trials in patients with conversion disorder.

To report on long-term clinical course in patients with symptomatic occipital lobe epilepsy secondary to neonatal hypoglycemia. Six patients with neonatal hypoglycemia and symptomatic occipital lobe epilepsy were studied in our hospital through reviewing their medical records retrospectively. The median onset age of epilepsy was 2 years 8 months and median follow-up period was 12 years and 4 months. Initial seizure types were generalized convulsions in 4 patients, hemiconvulsion in 1, and infantile spasms in 1. Ictal manifestations of main seizures were identical to occipital lobe seizures, such as eye deviation, eye blinking, ictal vomiting, and visual hallucination. Seizure frequency was maximum during infancy and early childhood and decreased thereafter with no seizure in 2 patients, a few seizures a year in 3, and once a month in 1. All patients had status epilepticus in the early course of epilepsy. EEGs showed parieto-occipital spikes in all patients. MRI revealed cortical atrophy and T2 prolongation parieto-occipitally in 4 patients, hippocampal atrophy in 1, and unremarkable in 1. This study indicates that epilepsy secondary to neonatal hypoglycemia is intractable during infancy and early childhood with frequent status epilepticus but tends to decrease in older age.

Purpose: To investigate childhood benign partial epilepsy (BPE) with SPECT. Methods: Double SPECT imaging was performed on 21 cases of BPE at the stage of wake (interval spike discharge) and sleep (spike discharge), under EEG monitoring. The transverse images were reconstructed after digital image subtraction. The quantitative analysis was conducted with brain flow change rate (BFCR) % mathematical model. Results: EEG monitoring demonstrated approximately normal background of 21 cases of BPE during the stage of wake, and spike discharge frequency markedly increased during the stage of sleep, 117 foci were showed by SPeCT in cases of BPE, and the average was 5.6 +- 1.6 foci/case. The characteristics of SPECT transverse images were 1) multiple foci of mirror, 2) mostly seen in Rolandic region, 3) circular symbol, 4) the radioactivity in foci decreased during the stage of wake (interval spike discharge) and increased during the stage of sleep (spike discharge). The concordance of SPECT and EEG was 93.1% (109/117 foci). The BFCR% of all epileptogenic foci exceeded normal limit (99% confidence interval). There was no correlation between the spike discharge frequency and BFCR% (r = 0.45, P>0.05). Conclusions: Regional cerebral blood flow and function were abnormal during the epileptogenic foci were discharging abnormally in BPE

Epilepsy can be divided into idiopathic epilepsy and symptomatic epilepsy according to the existence of underlying organic brain disease. It has been said that the incidence of the symptomatic epilepsy caused by underlying organic brain disease is higher in late-onset epilepsy after the age of 20 than in childhood-onset epilepsy. CT is very sensitive and non-invasive method for detection of organic brain disease. 168 cases of late-onset epilepsy after the age of of 20 were studied by CT in recent 2 years were analyzed. The results were as follows: 1. The 3rd decade was the most frequent age group, and the ratio of male to female was 2.5 : 1. 2. Structural abnormality on brain CT was demonstrated in 51.8% of the patient. 3. The older onset of age was, the higher the ratio of abnormal CT findings, except 5th decade which showed less CT abnormality than 4th decade. 4. The most frequent history related to epilepsy was trauma. 63.1% of patients had no relevant history: and they showed CT findings of brain tumor, atrophy and infraction in decreasing order of frequency. 5. Abnormal CT findings was demonstrated in 49.2% of normal neurologic examination and in 46.4% of normal EEG study. 6. The most frequent lesion of abnormal CT scan in late-onset epilepsy was 30 cases (18.4%) of brain atrophy. The next frequent lesion was 18 cases (10.7%) of brain tumor. Infarction, parasites and calcification were other frequent lesions

Few studies have been carried out in the same area at different times, allowing an assessment of the incidence of epilepsy (E.), including all ages, over time. The available data on temporal trend show a decrease in E. incidence in childhood and an increase in the elderly. We sought to update the incidence of E. in the province of Ferrara, where a previous study estimated an incidence rate of 33.1 per 100,000, 35.8, if standardized to the European population. Newly diagnosed patients aged up to 14 years were drawn from a community-based prospective multi-source registry, and adult onset E. cases were collected through multiple overlapping sources of case collection. Cases were included and classified according to ILAE recommendations. During the study period (2007-2008), 141 newly diagnosed cases (66 men and 75 women) living in the study area were identified. The crude incidence rate was 46.1 per 100,000 person-years (95 % CI 39.0-54.5), 35.5 (95 % CI 28.0-43.0) if adjusted to the European population. The incidence of childhood and adolescence epilepsy was 57.0 per 100,000 person-years (95 % CI 33.8-90.0), lower than that reported in our previous study, and it was 44.8 (95 % CI 37.4-53.6) for adult onset E., which is significantly higher as compared to our previous study. The overall incidence of E. in northern Italy is stable over time. We detected a significant decrease in incidence of childhood and adolescence E. and an increase in adult-onset E. The burden of epilepsy will increase as the population continues to age.

Up to 14% of children with epilepsy continue to experience seizures despite having appropriate medical therapy and develop medically refractory epilepsy (MRE). Assessing clinical outcomes and therapeutic efficacy in children with MRE undergoing palliative epilepsy surgery has been challenging because of the lack of a quantitative instrument capable of estimating the clinical status of these patients. The ideal instrument would at once consider seizure control, neurodevelopment, caregiver burden, and quality of life. The purpose of this study was to develop and pilot the Pediatric Refractory Epilepsy Questionnaire (PREQ), a quantitative instrument to assess the severity and individual burden of epilepsy in children with MRE undergoing palliative epilepsy treatments. The caregivers of 25 patients with MRE completed the PREQ and the Quality of Life in Childhood Epilepsy (QOLCE) measure and participated in a semistructured interview. Medical records of the patients were reviewed, an Early Childhood Epilepsy Severity Scale (E-CHESS) score was calculated, and a Global Assessment of Severity of Epilepsy (GASE) score was obtained for each patient. The initial PREQ was modified based on the analysis of responses, association with previously validated scales, comments from caregivers, and expertise of the PREQ panelists. Pediatric Refractory Epilepsy Questionnaire subscale scores were calculated based on clinical paradigm and compared with independent measures of seizure severity and quality of life. Significant correlations were observed between the seizure severity subscale and the GASE score (r=0.55) and between the mood subscale and the well-being score (r=0.61) on the QOLCE. Significant correlations were also observed between the caregiver rating of seizure severity and the GASE score (r=0.53), the social activity score (r=0.57), and the behavior score (r=0.43) on the QOLCE. Correlations between the caregiver rating of quality of life and the quality of life score (r=0

Single-Photon Emission Computed Tomography (SPECT) in childhood epilepsy

Gulati, Sheffali; Kalra, Veena; Bal, C.S.

The success of epilepsy surgery is determined strongly by the precise location of the epileptogenic focus. The information from clinical electrophysiological data needs to be strengthened by functional neuroimaging techniques. Single photon emission computed tomography (SPECT) available locally has proved useful as a localising investigation. It evaluates the regional cerebral blood flow and the comparison between ictal and interictal blood flow on SPECT has proved to be a sensitive nuclear marker for the site of seizure onset. Many studies justify the utility of SPECT in localising lesions to possess greater precision than interictal scalp EEG or anatomic neuroimaging. SPECT is of definitive value in temporal lobe epilepsy. Its role in extratemporal lobe epilepsy is less clearly defined. It is useful in various other generalized and partial seizure disorders including epileptic syndromes and helps in differentiating pseudoseizures from true seizures. The need for newer radiopharmaceutical agents with specific neurochemical properties and longer shelf life are under investigation. Subtraction ictal SPECT co-registered to MRI is a promising new modality. (author)

Elevated rates of affective disturbance in children with benign childhood epilepsy with centrotemporal spikes (BCECTS) have been reported. However, it remains unclear how anxiety and depression are related to epilepsy, and it is unknown whether these mood disorders are influenced by the use of antiepileptic drugs. In the present report, we performed a prospective study designed to evaluate affective disorders (anxiety and depression) without the bias of antiepileptic drug treatment in 89 children with BCECTS, based on self-reporting. Furthermore, we sought to determine whether clinical factors, such as age, disease course, seizure frequency, and spike wave index (SWI), were related to the psychological profiles. Patients with BCECTS (n = 89) and healthy matched controls (n = 75) were included in this study. The Depression Self-Rating Scale for Children (DSRSC) and the Screen for Child Anxiety-Related Emotional Disorders (SCARED) were completed by the children. None of the children met criteria for clinically significant anxiety or depression. However, the children with BCECTS had significantly higher depression and anxiety scores compared with children in the control group. We found no significant differences in depression or anxiety between the left, right, and bilateral lobe groups. The DSRSC scores were similar between the children with partial seizures and those with secondarily generalized seizures. Similarly, there were no significant differences in the SCARED scores between these two groups. However, the DSRSC and SCARED scores were positively correlated with age, seizure frequency, SWI, and disease course. The children with BCECTS had an increased likelihood of depression and anxiety, and these higher rates were unrelated to seizure type or epileptic focus, but were positively correlated with age, seizure frequency, SWI, and disease course.

In an retrospective uncontrolled long-term study in 30 children with intractable epilepsy, it was found that treatment with vigabatrin resulted in a seizure reduction of more than 50% at 1-year follow-up in 40% of the children. The responders were all children with partial seizures. Side effects...... were mild and did not lead to discontinuation of the drug. Increased numbers of seizures were seen in three cases. A moderate weight increase was seen in 27% of the children. At 5-year follow-up 7 children (23%) still maintained a seizure reduction of more than 50%. Trials of monotherapy in three...... seizure-free patients were unsuccessful. No further side effects were observed. A study of evoked potentials in 12 children showed no alteration in latency and amplitudes of VEP following treatment with vigabatrin. Our results show that in children vigabatrin seems to have a stable effect even though...

Dietary Therapies for Epilepsy

Full Text Available Since their introduction in 1921, high-fat, low-carbohydrate "ketogenic" diets have been used worldwide for refractory childhood epilepsy. Approximately half of the children have at least half their seizures reduced, including 15% who are seizure free. The mechanisms of action of dietary therapies are under active investigation and appear to involve mitochondria. Once perceived as a last resort, modifications to initiation and maintenance, as well as the widespread use of pre-made ketogenic formulas have allowed dietary treatment to be used earlier in the course of epilepsy. For infantile spasms (West syndrome specifically, the ketogenic diet is successful about 50% of the time as a first-line treatment. New "alternative" diets such as the modified Atkins diet were created in 2003 and can be started more easily and are less restrictive. They may have particular value for countries in Asia. Side effects include constipation, dyslipidemia, growth slowing, acidosis, and kidney stones. Additionally, neurologists are studying ketogenic diets for conditions other than epilepsy, including Alzheimer's disease, autism, and brain tumors.

As surgical treatments for adult and pediatric forms of epilepsy have become more refined, methods for noninvasive localization of epileptogenic foci have become increasingly important. Detection of focal brain metabolic or flow abnormalities is now well recognized as an essential step in the presurgical evaluation of many patients with epilepsy. Positron emission tomography (PET) scanning is most beneficial when used in the context of the total clinical evaluation of patients, including scalp EEG, invasive EEG, neuropsychologic testing, etc. Metabolic PET studies also give insight into pathophysiologic mechanisms of epilepsy. The dynamic nature of the interictal hypometabolism observed with 18(F)FDG in some patients suggests that excitatory or inhibitory neurotransmitters and their receptors may be involved. An exciting current application of PET scanning is the use of tracers for neurotransmitter receptors in the study of epilepsy patients. Mu and non-mu opiate receptors have been extensively studied and are beginning to give new insights into this disorder. Increased labeling of mu receptors in temporal neocortex using 11C-carfentanil has been demonstrated and, in some patients, supplements the clinical localization information from 18(F)FDG studies. Increased mu opiate receptor number or affinity is thought to play a role in anticonvulsant mechanisms. Specificity of increased mu receptors is supported by the absence of significant changes in non-mu opiate receptors. Other brain receptors are also of interest for future studies, particularly those for excitatory neurotransmitters. Combined studies of flow, metabolism, and neuroreceptors may elucidate the factors responsible for initiation and termination of seizures, thus improving patient treatment.95 references.

Hippocampal Sclerosis (HS) is widely recognized as a significant underlying cause of drug-resistant temporal lobe epilepsy (TLE) in adults. In contrast, HS is a rare finding in pediatric surgical series, and a higher incidence of HS associated with cortical dysplasia (i.e. FCD type IIIa according to the new ILAE classification) than in adult series has been reported. Data about the electro-clinical characteristics of this subgroup are scarce. We studied 15 children and adolescents with drug-resistant TLE and HS who had anterior temporal lobe resection at our center with regard to electroclinical characteristics, MRI features and histopathology. Children in whom histopathology was consistent with Focal Cortical Dysplasia (FCD) type IIIa (n = 7) were compared with those who had HS only (n = 8). Clinical characteristics associated with this highly selective subset of patients with FCD type IIIa were: the presence of febrile seizures during infancy, a shorter duration of active epilepsy and a lower age at epilepsy surgery. In addition, there were non-significant trends towards more extended abnormalities on both EEG and neuroimaging. We were, however, not able to find group differences with respect to neuropathologic subtyping of the HS. We present the first detailed description and comprehensive data analysis of children with FCD type IIIa. According to our results, this patient group seems to show a distinct clinical phenotype.

Full Text Available Vitamin D (VD is implicated in multiple aspects of human physiology and vitamin D receptor (VDR polymorphisms are associated with a variety of neuropsychiatric disorders. Although VD deficiency is highly prevalent in epilepsy patients and converging evidence indicates a role for VD in the development of epilepsy, no data is available on the possible relationship between epilepsy and genetic variations of VDR. In this study, 150 controls and 82 patients with temporal lobe epilepsy (TLE were genotyped for five common VDR polymorphisms (Cdx-2, FokI, BsmI, ApaI and TaqI by the polymerase chain reaction-ligase detection reaction method. Our results revealed that the frequency of FokI AC genotype was significantly higher in the control group than in the patients (p = 0.003, OR = 0.39, 95% CI = 0.21–0.73, whereas the AA genotype of ApaI SNP was more frequent in patients than in controls (p = 0.018, OR = 2.92, 95% CI = 1.2–7.1. However, no statistically significant association was found between Cdx-2, BsmI and TaqI polymorphisms and epilepsy. Additionally, in haplotype analysis, we found the haplotype GAT (BsmI/ApaI/TaqI conferred significantly increased risk for developing TLE (p = 0.039, OR = 1.62, 95% CI = 1.02–2.56. As far as we know, these results firstly underline the importance of VDR polymorphisms for the genetic susceptibility to epilepsy.

The absence epilepsies are presumed to be caused by genetic factors, but the influence of environmental exposures on epilepsy development and severity, and whether this influence is transmitted to subsequent generations, is not well known. We assessed the effects of environmental enrichment on epilepsy and anxiety outcomes in multiple generations of GAERS - a genetic rat model of absence epilepsy that manifests comorbid elevated anxiety-like behaviour. GAERS were exposed to environmental enrichment or standard housing beginning either prior to, or after epilepsy onset, and underwent EEG recordings and anxiety testing. Then, we exposed male GAERS to early enrichment or standard housing and generated F1 progeny, which also underwent EEG recordings. Hippocampal CRH mRNA expression and DNA methylation were assessed using RT-PCR and pyrosequencing, respectively. Early environmental enrichment delayed the onset of epilepsy in GAERS, and resulted in fewer seizures in adulthood, compared with standard housed GAERS. Enrichment also reduced the frequency of seizures when initiated in adulthood. Anxiety levels were reduced by enrichment, and these anti-epileptogenic and anxiolytic effects were heritable into the next generation. We also found reduced expression of CRH mRNA in GAERS exposed to enrichment, but this was not due to changes in DNA methylation. Environmental enrichment produces disease-modifying effects on genetically determined absence epilepsy and anxiety, and these beneficial effects are transferable to the subsequent generation. Reduced CRH expression was associated with these phenotypic improvements. Environmental stimulation holds promise as a naturalistic therapy for genetically determined epilepsy which may benefit subsequent generations. Copyright © 2016 Elsevier Inc. All rights reserved.

Age at onset in patients with medically refractory temporal lobe epilepsy and mesial temporal sclerosis: impact on clinical manifestations and postsurgical outcome.

To evaluate the demographic and clinical manifestations and postsurgical outcome of childhood-onset mesial temporal sclerosis and temporal lobe epilepsy (MTS-TLE) and establishing the potential differences as compared to the patients with adult-onset MTS-TLE. In this retrospective study all patients with a clinical diagnosis of medically refractory TLE due to mesial temporal sclerosis, who underwent epilepsy surgery at Jefferson comprehensive epilepsy center, were recruited. Patients were prospectively registered in a database from 1986 through 2014. Postsurgical outcome was classified into two groups; seizure-free or relapsed. Clinical manifestations and outcome were compared between patients with childhood-onset MTS-TLE (i.e., age at onset of the first afebrile habitual seizure below 10 years) and those with adult-onset MTS-TLE (i.e., age at onset of the first afebrile habitual seizure 20 years or above). One hundred and twelve patients had childhood-onset MTS-TLE and 76 had adult-onset MTS-TLE. Demographic, clinical, EEG and MRI characteristics of these two groups were similar. Postoperative outcome was not statistically different between these two groups of patients (P=0.9). Temporal lobe epilepsy due to mesial temporal sclerosis is a common cause of epilepsy that can start from early childhood to late adulthood. The etiology of MTS-TLE may be different in various age groups, but it seems that when mesial temporal sclerosis is the pathological substrate of TLE, clinical manifestations and response to surgical treatment of patients are very similar in patients with childhood-onset MTS-TLE compared to those with adult-onset disease.

Background: There is a complex interaction between female and male sex hormones and the risk of epilepsy. Whether prenatal exposure to higher levels of sex hormones affects the development of epilepsy in childhood or later in life is not well known. The sex hormone environment of fetuses may...... be affected by the sex of the co-twin. We estimated the risk of epilepsy for twins with an opposite-sex (OS) co-twin compared with twins with a same-sex (SS) co-twin.

Full Text Available Background: Ketogenic diet in children with epilepsy has a considerable impact on daily life and is usually adopted for at least 3 months. Our aim was to evaluate whether the introduction of an all-liquid ketogenic diet in an outpatient setting is feasible, and if an earlier assessment of its efficacy can be achieved. Methods: The authors conducted a prospective, observational study in a consecutive group of children with refractory epilepsy aged 2 to 14 years indicated for ketogenic diet. Ketogenic diet was started as an all-liquid formulation of the classical ketogenic diet, KetoCal 4:1 LQ, taken orally or by tube. After 6 weeks, the liquid diet was converted into solid meals. The primary outcome parameter was time-to-response (>50% seizure reduction. Secondary outcome parameters were time to achieve stable ketosis, the number of children showing a positive response, and the retention rate at 26 weeks. Results: Sixteen children were included. Four of them responded well with respect to seizure frequency, the median time-to-response was 14 days (range 7-28 days. The mean time to achieve stable ketosis was 7 days. The retention rate at 26 weeks was 50%. Of the 8 children who started this protocol orally fed, 6 completed it without requiring a nasogastric tube. Conclusions: Introduction of ketogenic diet with a liquid formulation can be accomplished in orally fed children without major complications. It allowed for fast and stable ketosis.

The incidence of epilepsy in Ethiopia is high compared with industrialised countries, but in most cases the cause of epilepsy is unknown. Childhood malnutrition remains widespread. We performed a case-control study to determine whether epilepsy is associated with poverty and markers of early under-nutrition. Patients with epilepsy (n=112), aged 18-45years, were recruited from epilepsy clinics in and around two towns in Ethiopia. Controls with a similar age and gender distribution (n=149) were recruited from patients and relatives attending general outpatient clinics. We administered a questionnaire to define the medical and social history of cases and controls, and then performed a series of anthropometric measurements. Unconditional logistic regression was used to estimate multivariate adjusted odds ratios. Multiple linear regression was used to estimate adjusted case-control differences for continuously distributed outcomes. Epilepsy was associated with illiteracy/low levels of education, odds ratio=3.0 (95% confidence interval: 1.7-5.6), subsistence farming, odds ratio=2.6 (1.2-5.6) and markers of poverty including poorer access to sanitation (p=0.009), greater overcrowding (p=0.008) and fewer possessions (ppoor education and markers of poverty. Patients with epilepsy also had evidence of stunting and disproportionate skeletal growth, raising the possibility of a link between early under-nutrition and epilepsy.

Ketogenic diet for epilepsy treatment

Directory of Open Access Journals (Sweden)

Letícia Pereira de Brito Sampaio

Full Text Available ABSTRACT The ketogenic diet (KD, a high-fat, low-carbohydrate, and adequate-protein diet is an established, effective nonpharmacologic treatment option for intractable childhood epilepsy. The KD was developed in 1921 and even though it has been increasingly used worldwide in the past decade, many neurologists are not familiar with this therapeutic approach. In the past few years, alternative and more flexible KD variants have been developed to make the treatment easier and more palatable while reducing side effects and making it available to larger group of refractory epilepsy patients. This review summarizes the history of the KD and the principles and efficacy of the classic ketogenic diet, medium-chain triglyceride(s (MCT ketogenic diet, modified Atkins diet, and low glycemic index treatment.

The objective of this study was to identify two-year trajectories of epilepsy-specific health-related quality of life (HRQOL) among children newly diagnosed with epilepsy and to evaluate the predictive value of a comprehensive set of medical, psychosocial, and family factors. Ninety-four children with epilepsy (8.14 ± 2.37 years of age and 63% male) and their caregivers participated in this study. Caregivers completed the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE) and measures of psychological and family functioning at one month postdiagnosis. The QOLCE was also given at eight additional time points during the subsequent two years as a part of a large observational study in children with epilepsy. Adherence data were collected via MEMS TrackCaps, and medical information was collected through chart review. Unique trajectories were identified for the overall QOLCE scale, as well as the subscales. Most trajectory models for the QOLCE subscales contained at least one at-risk trajectory for children, indicating that there is a subgroup of children experiencing poor long-term HRQOL. Health-related quality-of-life trajectories remained predominantly stable during the two-year period following treatment initiation. The number of AEDs, internalizing problems, and externalizing problems emerged as the most consistent predictors across the HRQOL domains. Medical and psychosocial interventions, such as cognitive-behavioral strategies, should target modifiable factors (e.g., internalizing symptoms, externalizing symptoms, number of AEDs trialed) shortly after diagnosis to improve HRQOL for children with epilepsy over the course of their disease.

Full Text Available Benign childhood epilepsy with centrotemporal spikes (BECTS is associated with cognitive and language problems. According to recent studies, disruptions in brain structure and function in children with BECTS are beyond a Rolandic focus, suggesting atypical cortical development. However, previous studies utilizing surface-based metrics (e.g., cortical gyrification and their structural covariance networks at high resolution in children with BECTS are limited. Twenty-six children with BECTS (15 males/11 females; 10.35 ± 2.91 years and 26 demographically matched controls (15 males/11 females; 11.35 ± 2.51 years were included in this study and subjected to high-resolution structural brain MRI scans. The gyrification index was calculated, and structural brain networks were reconstructed based on the covariance of the cortical folding. In the BECTS group, significantly increased gyrification was observed in the bilateral Sylvain fissures and the left pars triangularis, temporal, rostral middle frontal, lateral orbitofrontal, and supramarginal areas (cluster-corrected p < 0.05. Global brain network measures were not significantly different between the groups; however, the nodal alterations were most pronounced in the insular, frontal, temporal, and occipital lobes (FDR corrected, p < 0.05. In children with BECTS, brain hubs increased in number and tended to shift to sensorimotor and temporal areas. Furthermore, we observed significantly positive relationships between the gyrification index and age (vertex p < 0.001, cluster-level correction as well as duration of epilepsy (vertex p < 0.001, cluster-level correction. Our results suggest that BECTS may be a condition that features abnormal over-folding of the Sylvian fissures and uncoordinated development of structural wiring, disrupted nodal profiles of centrality, and shifted hub distribution, which potentially represents a neuroanatomical hallmark of BECTS in the

The diagnosis of epilepsy in children is known to impact the trajectory of their health-related quality of life (HRQOL) over time. However, there is limited knowledge about variations in longitudinal trajectories across multiple domains of HRQOL. This study aims to characterize the heterogeneity in HRQOL trajectories across multiple HRQOL domains and to evaluate predictors of differences among the identified trajectory groups in children with new-onset epilepsy. Data were obtained from the Health Related Quality of Life in Children with Epilepsy Study (HERQULES), a prospective multi-center study of 373 children newly diagnosed with new-onset epilepsy who were followed up over 2years. Child HRQOL and family factors were reported by parents, and clinical characteristics were reported by neurologists. Group-based multi-trajectory modeling was adopted to characterize longitudinal trajectories of HRQOL as measured by the individual domains of cognitive, emotional, physical, and social functioning in the 55-item Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55). Multinomial logistic regression was used to assess potential factors that explain differences among the identified latent trajectory groups. Three distinct HRQOL trajectory subgroups were identified in children with new-onset epilepsy based on HRQOL scores: "High" (44.7%), "Intermediate" (37.0%), and "Low" (18.3%). While most trajectory groups exhibited increasing scores over time on physical and social domains, both flat and declining trajectories were noted on emotional and cognitive domains. Less severe epilepsy, an absence of cognitive and behavioral problems, lower parental depression scores, better family functioning, and fewer family demands were associated with a "Higher" or "Intermediate" HRQOL trajectory. The course of HRQOL over time in children with new-onset epilepsy appears to follow one of three different trajectories. Addressing the clinical and psychosocial determinants identified

Full Text Available Anxiety disorders represent a prevalent psychiatric comorbidity in both adults and children with epilepsy for which the etiology remains controversial. Neurobiological contributions have been suggested, but only limited evidence suggests abnormal brain volumes particularly in children with epilepsy and anxiety. Since the brain develops in an organized fashion, covariance analyses between different brain regions can be investigated as a network and analyzed using graph theory methods. We examined 46 healthy children (HC and youth with recent onset idiopathic epilepsies with (n = 24 and without (n = 62 anxiety disorders. Graph theory (GT analyses based on the covariance between the volumes of 85 cortical/subcortical regions were investigated. Both groups with epilepsy demonstrated less inter-modular relationships in the synchronization of cortical/subcortical volumes compared to controls, with the epilepsy and anxiety group presenting the strongest modular organization. Frontal and occipital regions in non-anxious epilepsy, and areas throughout the brain in children with epilepsy and anxiety, showed the highest centrality compared to controls. Furthermore, most of the nodes correlating to amygdala volumes were subcortical structures, with the exception of the left insula and the right frontal pole, which presented high betweenness centrality (BC; therefore, their influence in the network is not necessarily local but potentially influencing other more distant regions. In conclusion, children with recent onset epilepsy and anxiety demonstrate large scale disruptions in cortical and subcortical brain regions. Network science may not only provide insight into the possible neurobiological correlates of important comorbidities of epilepsy, but also the ways that cortical and subcortical disruption occurs.

Variegate porphyria is an autosomal dominant disorder that usually presents with photosensitivity and acute neurological crises in adulthood. It is caused by heterozygous mutations in the protoporphyrinogen oxidase gene (PPOX). A rarer variant, homozygous variegate porphyria (HVP), presents in childhood with recurrent skin blisters and scarring. More variable features of HVP are short stature, brachydactyly, nystagmus, epilepsy, developmental delay and mental retardation. We describe a child who presented with nystagmus, developmental delay and ataxia, combined with a photosensitive eruption. Analysis of porphyrins in plasma, urine and stool supported a clinical diagnosis of HVP. DNA from the patient showed that he is compound heterozygous for two novel missense mutations in the PPOX coding region: c.169G>C (p.Gly57Arg) and c.1259C>G (Pro420Arg). Interestingly, cranial magnetic resonance imaging showed an absence of myelin, a feature not previously reported in HVP, which expands the differential diagnosis of childhood hypomyelinating leucoencephalopathies. © 2013 British Association of Dermatologists.

Angelman syndrome, cause of epilepsy in infants

Several chromosomal syndromes include brain dysfunction symptoms as mental retardation, developmental speech disorders and epilepsy. Authors present a case report of Angelman syndrome – neuro behavioral disorder associated with deletion in the maternal chromosome 15q 11-g13 causing mutation of the UBE3A gene. The main features consist of psychomotor retardation, developmental speech disorder, ataxia, tremor, hyperactivity, clapping hands, inadequate laughter and happiness, attention deficit and epilepsy. The later starts before the 3rd year of age in form of atypical absences, myoclonic and generalized tonic-clonic seizures. EEG typically shows episodes of slow activity with sharp waves occipitally. Prognosis is poor. Genetic syndromes importantly contribute to the etiology of epilepsy with early seizures. (author)

Disrupted sleep patterns in children with epilepsy and their parents are commonly described clinically. A number of studies have shown increased frequency of sleep disorders among pediatric epilepsy patients; however, few have characterized the association between epilepsy and parental sleep quality and household sleeping arrangements. The purpose of this study was to explore the effect of pediatric epilepsy on child sleep, parental sleep and fatigue, and parent-child sleeping arrangements, including room sharing and cosleeping. Parents of children 2 to 10 years of age with and without epilepsy completed written questionnaires assessing seizure history, child and parent sleep, and household sleeping arrangements. Children's Sleep Habits Questionnaire (CSHQ) scores were used to evaluate sleep disturbances for the child. The Pittsburgh Sleep Quality Index (PSQI) and the Iowa Fatigue Scale (IFS) were used to evaluate parental sleep and fatigue, respectively. The Early Childhood Epilepsy Severity Scale (E-Chess) was used to assess epilepsy severity. One hundred five households with a child with epilepsy and 79 controls participated in this study. Households with a child with epilepsy reported increased rates of both parent-child room sharing (p Children with epilepsy were found to have greater sleep disturbance by total CSHQ score (p Parents of children with epilepsy had increased sleep dysfunction (p = 0.005) and were more fatigued (p parental sleep dysfunction (0.273, p = 0.005), and parental fatigue (0.324, p = 0.001). Antiepileptic drug polytherapy was predictive of greater childhood sleep disturbances. Nocturnal seizures were associated with parental sleep problems, whereas room sharing and cosleeping behavior were associated with child sleep problems. Within the epilepsy cohort, 69% of parents felt concerned about night seizures and 44% reported feeling rested rarely or never. Finally, 62% of parents described decreased sleep quality and/or quantity with

Research suggests an increased risk for cognitive impairment in childhood epilepsy with memory being one area of cognition most likely to be affected. Understanding the prevalence and predictors of memory difficulties may help improve awareness of the difficulties and allow efficacious supports to be put in place. A systematic review was carried out using the search terms 'memory', 'children' and 'epilepsy' in the database PUBMED. Eighty-eight studies met inclusion criteria. The review focuses on comparisons of memory scores of children with epilepsy and controls, and comparison of memory scores of children with epilepsy to normative scores. Predictors of memory impairment and the effect of surgery on memory functioning are also reviewed. The majority (78%) of studies reviewed revealed that children with epilepsy scored lower than controls and normative scores on measures of memory. Post-surgery, memory scores were reported to improve in 50% of studies. Predictors of memory impairment included a greater number of AEDs used, younger age of onset, increased seizure frequency and longer duration of epilepsy. Children with epilepsy have a high frequency of memory impairments. However, the exact prevalence of difficulties is not clear due to the lack of population-based data. Most studies have not controlled for IQ and thus it is unclear if difficulties are always related to global cognitive difficulties. There is need for future population-based studies and studies focussing on the neurobiology of memory problems in children with epilepsy. Copyright © 2014 British Epilepsy Association.

Epilepsy, Cognition, and Behavior: The clinical picture

Science.gov (United States)

Berg, Anne T.

2010-01-01

Although epilepsy is defined by the occurrence of spontaneous epileptic seizures, a large body of evidence indicates that epilepsy is linked to a spectrum behavioral, psychiatric, and cognitive disorders as well as to sudden death. Explanations for these associations include: (1) The effects of structural lesions which may impair the functions subserved by the regions of the brain involved in the lesion. (2) The effects of seizure activity which may begin well before a clinical seizure occurs and may persist long after it is over raising questions about what truly constitutes “interictal.” In addition, encephalopathic effects of epilepsy in infancy during critical periods in development may be particularly severe and potentially irreversible. (3) Shared mechanisms underlying seizures as well as these other disorders in the absence of structural lesions or separate diseases of the CNS. Epidemiological and clinical studies demonstrate the elevated risk of cognitive, psychiatric, and behavioral disorders not just during but also prior to the onset of epilepsy (seizures) itself. These may outlast the active phase of epilepsy as well. The mounting evidence argues strongly for the recognition of epilepsy as part of a spectrum of disorders and against the notion that even uncomplicated epilepsy can a priori be considered benign.

The objective of this study was to evaluate the cortical thickness and the volume of deep gray matter structures, measured from 3D T1-weighted gradient echo imaging, and white matter integrity, by diffusion tensor imaging (DTI) in patients with typical absence epilepsy (AE). Patients (n = 19) with typical childhood AE and juvenile AE, currently taking antiepileptic medication, were compared with control subjects (n = 19), matched for gender and age. 3D T1 magnetization-prepared rapid gradient echo-weighted imaging and DTI along 30 noncolinear directions were performed using a 1.5-T MR scanner. FreeSurfer was used to perform cortical volumetric reconstruction and segmentation of deep gray matter structures. For tract-based spatial statistics analysis of DTI, a white matter skeleton was created, along with a permutation-based inference with 5000 permutations. A threshold of p < 0.05 was used to identify abnormalities in fractional anisotropy (FA). The mean, radial, and axial diffusivities were also projected onto the mean FA skeleton. Patients with AE presented decreased FA and increased mean diffusivity and radial diffusivity values in the genu and the body of the corpus callosum and right anterior corona radiata, as well as decreased axial diffusivity in the left posterior thalamic radiation, inferior cerebellar peduncle, right cerebral peduncle, and right corticospinal tract. However, there were no significant differences in cortical thickness or deep gray matter structure volumes between patients with AE and controls. Abnormalities found in white matter integrity may help to better understand the pathophysiology of AE and optimize diagnosis and treatment strategies. (orig.)

In the current study, we explored the prevalence of physician-confirmed seizure clusters. We also investigated potential clinical factors associated with the occurrence of seizure clusters overall and by epilepsy type. We reviewed medical records of 4116 adult (≥16years old) outpatients with epilepsy at our centers for documentation of seizure clusters. Variables including patient demographics, epilepsy details, medical and psychiatric history, AED history, and epilepsy risk factors were then tested against history of seizure clusters. Patients were then divided into focal epilepsy, idiopathic generalized epilepsy (IGE), or symptomatic generalized epilepsy (SGE), and the same analysis was run. Overall, seizure clusters were independently associated with earlier age of seizure onset, symptomatic generalized epilepsy (SGE), central nervous system (CNS) infection, cortical dysplasia, status epilepticus, absence of 1-year seizure freedom, and having failed 2 or more AEDs (Pepilepsy (16.3%) and IGE (7.4%; all Pepilepsy type showed that absence of 1-year seizure freedom since starting treatment at one of our centers was associated with seizure clustering in patients across all 3 epilepsy types. In patients with SGE, clusters were associated with perinatal/congenital brain injury. In patients with focal epilepsy, clusters were associated with younger age of seizure onset, complex partial seizures, cortical dysplasia, status epilepticus, CNS infection, and having failed 2 or more AEDs. In patients with IGE, clusters were associated with presence of an aura. Only 43.5% of patients with seizure clusters were prescribed rescue medications. Patients with intractable epilepsy are at a higher risk of developing seizure clusters. Factors such as having SGE, CNS infection, cortical dysplasia, status epilepticus or an early seizure onset, can also independently increase one's chance of having seizure clusters. Copyright © 2017.

Epilepsy is a chronic medical condition with many co-morbid features. It has been observed that children with epilepsy (CWE) have a compromised quality of life (QOL). To assess the QOL in CWE and to study the various factors affecting QOL among CWE. The sample consisted of 102 CWE aged 5-15 years of either sex. QOL was measured by Quality of Life in Childhood Epilepsy (QOLCE) questionnaire, a 76-item, parent-reported questionnaire. Cronbach alpha was used to determine the internal consistency of the subscales and Pearson correlation to determine construct validity. The t-test and analysis of variance were used to compare mean QOLCE scores. Factors affecting QOL included age, place of residence, socioeconomic condition, maternal education, seizure type and frequency and number of antiepileptic drugs. CWE have a relatively compromised QOL and comprehensive care needs to go beyond the attempt of controlling seizures.

The objectives of the current study were to examine whether eating in the absence of hunger (EAH) at age 7 predicted reports of self-reported binge eating at age 15 and to identify factors among girls with high-EAH that moderated risk of later binge eating. Subjects included 158 girls assessed at age 7 and age 15. Logistic regression was used to predict binge eating at age 15 from calories consumed during EAH at age 7. A series of logistic regressions were used to examine the odds of reporting binge eating given levels of risk factors (e.g., anxiety) among those with high-EAH in childhood. Girls' EAH intake predicted reports of binge eating at age 15; after adjusting for age 7 BMI, for each additional 100kcal consumed, girls were 1.7 times more likely to report binge eating in adolescence. Among those with high-EAH, BMI, anxiety, depression, dietary restraint, emotional disinhibition, and body dissatisfaction all predicted binge eating. EAH during childhood predicted reports of binge eating during adolescence; girls with elevated BMI, negative affect, and maladaptive eating- and weight-related cognitions were at increased risk. High-EAH in childhood may be useful for indicating those at risk for developing binge eating. Copyright © 2016 Elsevier Ltd. All rights reserved.

Children with epilepsy are reported to be at a greater risk of injuries compared with their peers who do not have epilepsy. We set out to determine the frequency and pattern of seizure-related injuries in children with epilepsy seen at the University College Hospital (UCH), Ibadan, Nigeria. Consecutive cases of epilepsy seen at the pediatric neurology clinic of the UCH, Ibadan over a period of 6months were evaluated for injuries in the preceding 12months using a structured questionnaire. These were compared with age- and sex-matched controls. A total of 125 children with epilepsy and 125 age- and sex-matched controls were studied. Injuries occurred more frequently in children with epilepsy than in their peers (p=0.01, OR 1.935, 95% CI 1.142-3.280). Epilepsy was generalized in 80 (64.0%), and localization-related in 45 (36.0%). Idiopathic epilepsy accounted for 74 (59.2%), and the remaining 51 (40.8%) had remote symptomatic epilepsy. Fifty-seven (45.6%) children had suffered seizure-related injuries with multiple injuries in 31 (24.8%). The most frequent were skin/soft tissue lacerations (26.4%), injuries to the tongue and soft tissues of the mouth (19.2%), minor head injuries (15.2%), and dental injuries with tooth loss (8.0%). There was a statistically significant association between seizure frequency and seizure-related injuries (p=0.002). Children on polytherapy had a significantly higher frequency of seizure-related injuries (pEpilepsy is a major risk factor for injuries in childhood.

The understanding of causation of epilepsy, especially in resource poor African countries where prevalence rates are very high, would aid strategies for primary prevention. This study sought to determine the causes of epilepsy in Nigerian Africans and health-itinerary of patients with epilepsy. This was an observational, cross-sectional descriptive study of consecutive newly diagnosed adult patients with epilepsy using a mixed-methods approach of face-to-face in-depth interview of patients' parents and relations, health care personnel who had given medical attention at any time and telephone interview. A structured interview schedule was used to obtain demographic information, details of seizure variables, health seeking itinerary and history of previous hospitalizations. Data was analyzed descriptively with SPSS version 17. Three hundred and forty-two patients with epilepsy with a mean age of 31.4±11.98 years participated in the study. Most of the patients (68.1%; 233/342) were unemployed and students. There were 270 (78.9%) patients with generalized epilepsy. No identifiable etiology was found in 37.7%, but of the remaining 62.3%, the commonest causes included post traumatic (19.6%), recurrent childhood febrile convulsions (13.2%), post-stroke (6.7%), brain tumors (5.9%), neonatal jaundice (5.3%), birth-related asphyxia (5%) and history of previous CNS infections (4.7%). Family history of epilepsy was obtained in 9.9%, all of whom had primarily generalized seizures. 61.4% of them sought initial attention from the traditional healers or in prayer houses. This study showed the pattern of causes of epilepsy in Nigerian Africans. The health seeking behavior and itinerary of the PWE revealed a preference for traditional healers. There is need for health policies and epilepsy awareness campaigns to prevent causes of seizures and improve the knowledge of the public respectively. Copyright © 2013 British Epilepsy Association.

Full Text Available Background: Epilepsy is a chronic medical condition with many co-morbid features. It has been observed that children with epilepsy (CWE have a compromised quality of life (QOL. Objective: To assess the QOL in CWE and to study the various factors affecting QOL among CWE. Materials and Methods: The sample consisted of 102 CWE aged 5-15 years of either sex. QOL was measured by Quality of Life in Childhood Epilepsy (QOLCE questionnaire, a 76-item, parent-reported questionnaire. Cronbach alpha was used to determine the internal consistency of the subscales and Pearson correlation to determine construct validity. The t-test and analysis of variance were used to compare mean QOLCE scores. Results: Factors affecting QOL included age, place of residence, socioeconomic condition, maternal education, seizure type and frequency and number of antiepileptic drugs. Conclusion: CWE have a relatively compromised QOL and comprehensive care needs to go beyond the attempt of controlling seizures.

Magnetic resonance imaging in the brain was performed in 293 patients with childhood-onset (<15 y.o.) epilepsy who had been classified into 4 groups, idiopathic localization-related epilepsy (ILRE), 78 patients; idiopathic generalized epilepsy (IGE), 116 patients; symptomatic localization-related epilepsy (SLRE), 68 patients and symptomatic generalized epilepsy (SGE), 31 patients, with the Classification of Epilepsies and Epileptic Syndrome (1989 International League Against Epilepsy). The examination was performed with a 1.5 T magnet. One hundred twenty-five patients (42.7%) showed abnormal findings, and the incidence in each group was as follows: Idiopathic epilepsy: The rate of abnormal findings in the ILRE and IGE groups was 21.8% and 20.7%, respectively. Most of the abnormal findings were secondary changes, such as diffuse or localized brain atrophy. Of the congenital abnormalities, the main finding was arachnoid cyst. Symptomatic epilepsy: The rate of abnormality in the SLRE patients was 88.2%, and 85% of the findings were secondary changes, i.e., brain atrophy, or degeneration of the white matter. In the SGE group, the rate was 77.4%, with an almost equal percentage of congenital and secondary changes. Of 255 patients who were examined by electroencephalography (EEG) on the same day as MRI, about 50% showed a correlation between the EEG records and the MRI abnormalities. However, only 8 patients showed a correlation in localization between the EEG and MRI abnormalities. (author)

2015-10-01

The aim of this prospective blinded study was to evaluate an automated algorithm for spike-and-wave discharge (SWD) detection applied to EEGs from genetic absence epilepsy rats from Strasbourg (GAERS). Five GAERS underwent four sessions of 20-min EEG recording. Each EEG was manually analyzed for SWDs longer than one second by two investigators and automatically using an algorithm developed in MATLAB®. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for the manual (reference) versus the automatic (test) methods. The results showed that the algorithm had specificity, sensitivity, PPV and NPV >94%, comparable to published methods that are based on analyzing EEG changes in the frequency domain. This provides a good alternative as a method designed to mimic human manual marking in the time domain.

Epilepsy and Autism: Is there a special relationship?

Science.gov (United States)

Berg, Anne T.; Plioplys, Sigita

2012-01-01

Increasingly, there has been an interest in the association between epilepsy and autism. The high frequency of autism in some of the early-onset developmental encephalopathic epilepsies is frequently cited as evidence of the relationship between autism and epilepsy. While these specific forms of epilepsy carry a higher than expected risk of autism, most if not all of the association may be due to intellectual disability (ID). The high prevalence of interictal EEG discharges in children with autism is also cited as further evidence although errors in the diagnosis of epilepsy seem to account for at least part of those findings. The prevalence of ID is substantially elevated in children with either epilepsy or autism. In the absence of ID, there is little evidence of a substantial, if any, increased risk of autism in children with epilepsy. Further, although the reported prevalence of autism has increased over the last several years, much of this increase may be attributable to changes in diagnostic practices, conceptualization of autism in the presence of ID, and laws requiring provision of services for children with autism. In the context of these temporal trends, any further efforts to tease apart the relationships between epilepsy, ID, and autism will have to address head-on the accuracy of diagnosis of all three conditions before we can determine whether there is indeed a special relationship between autism and epilepsy.

Full Text Available Introduction: Epilepsy is one of the most common neurological illnesses occurring in children. In approximately 20–30% of cases it is drug-resistant. Aim of the research: To assess the already-known risk factors, analyse the rarely described ones, and find new causes of epilepsy drug resistance in children, taking into account the level of impact of each factor. Material and methods : The study comprised 152 of all 383 children hospitalised in 2012 at the Neurology Department of the Polish Mother’s Memorial Hospital in Lodz due to epilepsy. Based on medical documentation, neurological examination, and our own questionnaire, we divided patients into two groups: drug-resistant epilepsy or drug-sensitive epilepsy. We compared the type, level of influence, and prevalence of different factors. For statistical analysis, the 2 test was used. Statistical significance was set at p < 0.05. Results: Drug-resistant epilepsy was found in 64 patients (42.1%, and drug-sensitive epilepsy was found in 88 patients (57.9%. Factors that were most probable to cause drug resistance included: high prevalence of seizures (Cramer’s V = 0.66, type of epileptic syndrome (V = 0.62, psychomotor developmental delay (V = 0.62, and occurrence of status epilepticus (V = 0.6. Factors such as infections of CNS in early childhood, repeated severe infections of airways in childhood, and mother’s infectious diseases with high fever during pregnancy were rare or non occurring (Cramer’s V = 0.41, 0.32, and 0.31, respectively. Conclusions : The study confirmed the previously known causes of drug resistance and indicated the significance of underestimated inflammatory and infectious factors involving pyrexia, in children and also in mothers during pregnancy.

Epilepsy in patients with autism: links, risks and treatment challenges

Full Text Available Frank MC Besag Neurodevelopmental Team, East London Foundation NHS Trust, Family Consultation Clinic, Bedford, UK Abstract: Autism is more common in people with epilepsy, approximately 20%, and epilepsy is more common in people with autism with reported rates of approximately 20%. However, these figures are likely to be affected by the current broader criteria for autism spectrum disorder (ASD, which have contributed to an increased prevalence of autism, with the result that the rate for ASD in epilepsy is likely to be higher and the figure for epilepsy in ASD is likely to be lower. Some evidence suggests that there are two peaks of epilepsy onset in autism, in infancy and adolescence. The rate of autism in epilepsy is much higher in those with intellectual disability. In conditions such as the Landau–Kleffner syndrome and nonconvulsive status epilepticus, the epilepsy itself may present with autistic features. There is no plausible mechanism for autism causing epilepsy, however. The co-occurrence of autism and epilepsy is almost certainly the result of underlying factors predisposing to both conditions, including both genetic and environmental factors. Conditions such as attention deficit hyperactivity disorder, anxiety and sleep disorders are common in both epilepsy and autism. Epilepsy is generally not a contraindication to treating these conditions with suitable medication, but it is important to take account of relevant drug interactions. One of the greatest challenges in autism is to determine why early childhood regression occurs in perhaps 25%. Further research should focus on finding the cause for such regression. Whether epilepsy plays a role in the regression of a subgroup of children with autism who lose skills remains to be determined.

Epilepsy after cerebral infection: review of the literature and the potential for surgery.

Science.gov (United States)

Ramantani, Georgia; Holthausen, Hans

2017-06-01

The risk of unprovoked seizures in population-based cohorts of cerebral infection survivors is 7-8% in developed countries, rising to considerably higher rates in resource-poor countries. The main risk factors for epilepsy after cerebral infection, besides acute seizures, are infection-associated brain lesions and status epilepticus during the acute phase. Despite the high prevalence of pharmacoresistant epilepsies after cerebral infections, especially in patients with MRI-identifiable lesions, only a small minority undergoes epilepsy surgery. However, excellent surgical candidates are particularly those with a history of meningitis or encephalitis in early childhood, hippocampal sclerosis on MRI, as well as a history, seizure semiology, and EEG-findings compatible with the diagnosis of a mesial temporal lobe epilepsy syndrome. More challenging are patients with neocortical/extratemporal lobe epilepsies post cerebral infection. Finally, patients with a severe hemispheric injury with contralateral hemiparesis are candidates for hemispherectomy/hemispherotomy. This review attempts to shed some light on this frequent cause of symptomatic focal epilepsy, with an emphasis on the chances offered by epilepsy surgery.

Basal levels of metabolic activity are elevated in Genetic Absence Epilepsy Rats from Strasbourg (GAERS): measurement of regional activity of cytochrome oxidase and lactate dehydrogenase by histochemistry.

The Genetic Absence Epilepsy Rats from Strasbourg (GAERS) are considered an isomorphic, predictive, and homologous model of human generalized absence epilepsy. It is characterized by the expression of spike-and-wave discharges in the thalamus and cortex. In this strain, basal regional rates of cerebral glucose utilization measured by the quantitative autoradiographic [(14)C]2-deoxyglucose technique display a widespread consistent increase compared to a selected strain of genetically nonepileptic rats (NE). In order to verify whether these high rates of glucose metabolism are paralleled by elevated activities of the enzymes of the glycolytic and tricarboxylic acid cycle pathways, we measured by histochemistry the regional activity of the two key enzymes of glucose metabolism, lactate dehydrogenase (LDH) for the anaerobic pathway and cytochrome oxidase (CO) for the aerobic pathway coupled to oxidative phosphorylation. CO and LDH activities were significantly higher in GAERS than in NE rats in 24 and 28 of the 30 brain regions studied, respectively. The differences in CO and LDH activity between both strains were widespread, affected all brain systems studied, and ranged from 12 to 63%. The data of the present study confirm the generalized increase in cerebral glucose metabolism in GAERS, occurring both at the glycolytic and at the oxidative step. However, they still do not allow us to understand why the ubiquitous mutation(s) generates spike-and-wave discharges only in the thalamocortical circuit.

ABSTRACT The ketogenic diet (KD), a high-fat, low-carbohydrate, and adequate-protein diet is an established, effective nonpharmacologic treatment option for intractable childhood epilepsy. The KD was developed in 1921 and even though it has been increasingly used worldwide in the past decade, many neurologists are not familiar with this therapeutic approach. In the past few years, alternative and more flexible KD variants have been developed to make the treatment easier and more palatable whi...

The study was designed to evaluate the efficacy, safety, and tolerability of the ketogenic diet (KD) whether classic 4:1 formula or the modified Atkins diet (MAD) in intractable childhood epilepsy. Anthropometric measurements and serum lipid profile were measured upon enrollment and after 3 and 6 months in 40 patients with symptomatic intractable epilepsy. Fifteen were given MAD diet, ten were kept on classic 4:1 ketogenic liquid formula, and the rest were allowed to eat as desired. The liquid ketogenic formula group showed significantly higher body mass index compared with those who did not receive KD after 6 months. The lipid profile of KD patients was within normal limits for age and sex during the study period. The rate of change of frequency and severity of seizures showed best improvement in ketogenic liquid formula patients followed by the MAD group than the patients on anti-epileptic medications alone. The KD whether classic 4:1 or MAD is a tolerable, safe, and effective adjuvant therapy for intractable symptomatic childhood epilepsy with limited adverse effects on the growth parameters and accepted changes in the lipid profile. The liquid ketogenic formula patients showed better growth pattern and significantly more seizure control. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Children and adolescents with epilepsy often show higher rates of executive functioning deficits and are at an increased risk of diminished health-related quality of life (HRQOL). The purpose of the current study was to determine the extent to which executive dysfunction predicts HRQOL in youth with epilepsy. Data included parental ratings on the Behavior Rating Inventory of Executive Function (BRIEF) and the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire for 130 children and adolescents with epilepsy (mean age=11years, 6months; SD=3years, 6months). Our results identified executive dysfunction in nearly half of the sample (49%). Moderate-to-large correlations were identified between the BRIEF and the QOLCE subscales of well-being, cognition, and behavior. The working memory subscale on the BRIEF emerged as the sole significant predictor of HRQOL. These results underscore the significant role of executive function in pediatric epilepsy. Proactive screening for executive dysfunction to identify those at risk of poor HRQOL is merited, and these results bring to question the potential role of behavioral interventions to improve HRQOL in pediatric epilepsy by specifically treating and/or accommodating for executive deficits.

Considerable disease variability exists between patients with epilepsy, and the societal costs for epilepsy care are overall high, because of high frequency in the general population especially in children from developing countries. A cross-sectional study where children with established diagnosis of epilepsy were interviewed using a semi-structured questionnaire. Prevalence-based costs were stratified by patients' sociodemographic characteristics and socioeconomic scores (SES). The 'bottom-up' and 'human capital' approaches were used to generate estimates on the direct and indirect (productivity losses) costs of epilepsy, respectively. All estimates of the financial burden of epilepsy were analyzed from the 'societal perspective' using IBM SPSS statistics software, version 20.0. The study had 103 enrollees with most in the age group of 0-5years (45.6%). Majority (61.3%) belong to the low socioeconomic class (Ogunlesi SES class IV and V) and reside (80.6%) in an urban setting. The total direct and indirect costs per month were ₦2,149,965.00 ($8497.88) and ₦363,187.80 ($1435.52), respectively. The cost of care per patient per annum was ₦292,794.50 ($1157.29), and the total cost for all the patients per year was ₦30,157,833.60 ($119,200.92). Investigative procedures are the principal cost drivers (₦15,861.17 or $18.15) comprising approximately 58.7% of the total direct costs per patient. Cost of investigations contributed immensely to the total direct cost of care in our study. With the present economic situation in the country, out-of-pocket payments may contribute significantly to catastrophic expenditures and worsening of secondary treatment gap in children with epilepsy.

2016-06-01

To provide a review on the spectrum of migraine-epilepsy disorders in children. The migraine-epilepsy continuum covers a fascinating array of disorders that share many clinical similarities but also differ fundamentally in pathophysiology. In the pediatric population, its study can be complicated by the young age of those affected and the lack of clear understanding of the neurobiology of these disorders within the developing brain. This review serves to discuss the borderland of migraine and epilepsy in children. It will focus on epidemiology and comorbidity of the two disorders, possible mechanisms for shared pathophysiology informed by basic and translational science, and an overview of clinical similarities and differences. It will also discuss differentiation of migraine aura from childhood occipital epilepsies. Finally, the review concludes with a discussion of current classification methods for capturing cases on the migraine-epilepsy spectrum and a call for a united approach towards a better definition of this spectrum of disorders. Recent advances examining the migraine-epilepsy spectrum show clinicopathological similarities between the two disorders in children. Epidemiology demonstrates reciprocally increased incidences of epilepsy in migraineurs and of migraines in children with epilepsy, however, prospective longitudinal in children are currently lacking. Clinically, the two disorders show similarity in preictal, ictal, and postictal phenomena, with close temporal association of the two conditions described by the controversial term of "migralepsy." Basic science research has contributed significant improvements in understanding the generation of both of these episodic neurological conditions, with common links seen at a cellular level involving synaptic glutamate release and the provocation of varying propagation methods including cortical spreading depression in migraine and the paroxysmal depolarizing shift in epilepsy. Despite these significant

Dilemmas in diagnostics and therapy of rolandic epilepsy

Directory of Open Access Journals (Sweden)

Škrijelj Fadil

2011-01-01

Full Text Available Introduction. It is considered that around 20%-30% of patients of all ages and in all continents have wrong epilepsy diagnoses. Diagnostic and consequential therapeutic errors appear, most often, when an adequate diagnostics is not applied. Benign focal epilepsy of childhoods with centrotemporal spikes-rolandic epilepsy, brings very often to diagnostic and therapeutic problems because of persistence of epilepticforms changes in an electroencephalography (EEG recording, several years after establishment of good control over seizures. Case report. We presented 8.5 years-old girl, with the first and the only epileptic seizure at the age of 5, during her sleep. With a clear correlation of EEG record, benign rolandic epilepsy was diagnosed, so the therapy with valproate was introduced. There were no seizures after three years of its implementation. Because of epileptic-forms changes that still persisted in EEG record during her sleep, it was suggested to further use valproate. However, after reconsidering all circumstances it was concluded that the AED should bee slowly reduced up to its exclusion. After a complete stoppage of the therapy, the patient did not have any epileptic seizure for nine months, although EEG still remained pathologically changed during her sleep. Conclusion. A changed EEG record in a patient with rolandic epilepsy must not be a predictor of continuation of antiepileptic drugs therapy, after 2-3 years of successful seizures remission.

Controlling absence seizures by deep brain stimulus applied on substantia nigra pars reticulata and cortex

International Nuclear Information System (INIS)

Hu, Bing; Wang, Qingyun

2015-01-01

Epilepsy is a typical neural disease in nervous system, and the control of seizures is very important for treating the epilepsy. It is well known that the drug treatment is the main strategy for controlling the epilepsy. However, there are about 10–15 percent of patients, whose seizures cannot be effectively controlled by means of the drug. Alternatively, the deep brain stimulus (DBS) technology is a feasible method to control the serious seizures. However, theoretical explorations of DBS are still absent, and need to be further made. Presently, we will explore to control the absence seizures by introducing the DBS to a basal ganglia thalamocortical network model. In particular, we apply DBS onto substantia nigra pars reticulata (SNr) and the cortex to explore its effects on controlling absence seizures, respectively. We can find that the absence seizure can be well controlled within suitable parameter ranges by tuning the period and duration of current stimulation as DBS is implemented in the SNr. And also, as the DBS is applied onto the cortex, it is shown that for the ranges of present parameters, only adjusting the duration of current stimulation is an effective control method for the absence seizures. The obtained results can have better understanding for the mechanism of DBS in the medical treatment.

There is a recently well-documented association between childhood epilepsy and earlysymptomaticsyndromeselicitingneurodevelopmentalclinicalexaminations (ESSENCE) including autism spectrum disorder, but the relationship between febrile seizures and ESSENCE is less clear. The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing population-based study targeting twins born in Sweden since July 1, 1992. Parents of 27,092 twins were interviewed using a validated DSM-IV-based interview for ESSENCE, in connection with the twins' ninth or twelfth birthday. Diagnoses of febrile seizures (n = 492) and epilepsy (n = 282) were based on data from the Swedish National Patient Register. Prevalence of ESSENCE in individuals with febrile seizures and epilepsy was compared with prevalence in the twin population without seizures. The association between febrile seizures and ESSENCE was considered before and after adjustment for epilepsy. Age of diagnosis of febrile seizures and epilepsy was considered as a possible correlate of ESSENCE in febrile seizures and epilepsy. The rate of ESSENCE in febrile seizures and epilepsy was significantly higher than in the total population without seizures (all P epilepsy, a significant association between febrile seizures and autism spectrum disorder, developmental coordination disorder, and intellectual disability remained. Earlier age of onset was associated with all ESSENCE except attention-deficit/hyperactivity disorder in epilepsy but not with ESSENCE in febrile seizures. In a nationally representative sample of twins, there was an increased rate of ESSENCE in childhood epilepsy and in febrile seizures. Febrile seizures alone could occur as a marker for a broader ESSENCE phenotype. Copyright © 2017 Elsevier Inc. All rights reserved.

Parental coping and childhood epilepsy: the need for future research.

2011-02-01

Parents of children with epilepsy, like parents of children with many other chronic conditions, are faced with a constant feeling of uncertainty about their child's condition. This uncertainty can lead to a decreased ability to cope as evidenced by increased stress levels, negative mood states, and impaired family functioning. Because altered coping in the parent may have a profound negative impact on the child's psychosocial adjustment to living with a chronic condition, it is important to identify ways to facilitate positive coping skills in the parent. The purpose of this review was to critically analyze the existing literature related to the challenges associated with parenting a child who has epilepsy. Interventions geared toward facilitating coping in parents will also be reviewed, and gaps in the literature will be identified. Lastly, future implications for nursing research will be discussed.

The effects of epilepsy may disturb the ability of the child and family to function and has detrimental effects on health-related quality of life (HRQOL). We determined HRQOL and related factors in children and adolescents with epilepsy in Iran. This cross-sectional study was performed in a private neurology pediatric clinic in Guilan Province (North of Iran). We evaluated 108 children and adolescents with epilepsy. Data were collected by interview with parents and review of medical records. Generic and specific HRQOL was evaluated by Child Health Questionnaire and QOL in Childhood Epilepsy Questionnaire, respectively. The mean of overall generic HRQOL score was 71.05 ± 11.31. The lowest score was related to parental impact: emotional (52.59 ± 15.49). The average total specific HRQOL score was 71.95 ± 11.16. The lowest score dedicated to general health (51.21 ± 18.25). In multivariate regression analysis, duration of epilepsy (p epilepsy (p epilepsy (p epilepsy duration was the strongest predictor of both generic and specific HRQOL in children and adolescents with epilepsy. This will be useful for clinicians in epilepsy management, which will enhance HRQOL.

Full Text Available Tics are the most common forms of hyperkinesis among children and adolescents, the etiology of which is not fully clear. A study has shown a high comorbidity of tic disorders and epilepsy, as evidenced by video-EEG monitoring. In patients with tics even in the absence of epileptic seizures, epileptiform activity is an adverse predictor and a determinant of the potential risk of comorbid epilepsy especially during neuroleptic therapy. Antiepileptic drugs are the drugs of choice to treat this category of patients.

Peri-ictal water drinking (PIWD) has been reported as the action of drinking during or within two minutes of an electroclinical seizure. It is considered a peri-ictal vegetative symptom, evident both during childhood and adulthood epilepsy. The aim of this paper was to describe the clinical and electroencephalographic features of two new adult subjects suffering from symptomatic temporal lobe epilepsy with episodes of PIWD recorded by VIDEO-EEG and to review literature data in order to better define this peculiar event during seizures, a rare and probably underestimated semiological sign. To date, 51 cases with focal epilepsy and seizures associated with PIWD have been reported. All patients presented with temporal lobe epilepsy. All cases but one had symptomatic epilepsy. Most of the patients had an involvement of the right hemisphere. Water drinking was reported as an ictal sign in the majority of patients, and less frequently was reported as postictal. We believe that PIWD might be considered a rare automatic behaviour, like other automatisms. Automatisms are more frequently described in patients with temporal lobe epilepsy. PIWD was reported also to have lateralizing significance in the non-dominant temporal lobe, however, because of its rarity, this finding remains unclear.

The aim of the study was to compare sleep patterns in children with epilepsy with those of their non-epileptic siblings and to determine which epilepsy-specific factors predict greater sleep disturbance. We conducted a case-control study of 55 children with epilepsy (mean age 10y, range 4 to 16y; 27 males, 28 females) and their nearest-aged non-epileptic sibling (mean age 10y, range 4 to 18y; 26 males, 29 females). Epilepsy was idiopathic generalized in eight children (15%), symptomatic generalized in seven (13%), and focal in 40 (73%); the mean duration was 5 years 8 months. Parents or caregivers completed the Sleep Behavior Questionnaire (SBQ) and Child Behavior Checklist (CBCL) for patients and controls, and the Quality of Life in Childhood Epilepsy (QOLCE) for patients. Patients had a higher (more adverse) Total Sleep score (p<0.001) and scored worse than controls on nearly all subscales of the SBQ. In patients, higher Total Sleep scores were correlated with higher scores on the Withdrawn, Somatic complaints, Social problems, and Attention subscales of the CBCL, and significantly lower Total Quality of Life Scores. Refractory epilepsy, mental retardation, and remote symptomatic etiology predicted greater sleep problems in those with epilepsy. We conclude that children with epilepsy in this current study had significantly greater sleep problems than their non-epileptic siblings.

Temporal lobe encephaloceles can be associated with temporal lobe epilepsy. The authors report on the case of an adolescent with multiple microencephaloceles, in the anterolateral middle fossa floor, identified at surgery (temporal lobectomy) for intractable partial-onset seizures of temporal origin. Magnetic resonance imaging revealed only hippocampal atrophy. Subdural electrodes demonstrated ictal activity arising primarily from the anterior and lateral temporal lobe, close to the microencephaloceles, spreading to the anterior and posterior mesial structures. Pathological examination revealed diffuse temporal gliosis involving the hippocampus, together with microdysgenesis of the amygdala. The literature on epilepsy secondary to encephaloceles is reviewed and the contribution of the microencephaloceles to the seizure disorder in this patient is discussed.

Classification of childhood epilepsies in a tertiary pediatric neurology clinic using a customized classification scheme from the international league against epilepsy 2010 report.

2013-01-01

In its 2010 report, the International League Against Epilepsy Commission on Classification and Terminology had made a number of changes to the organization, terminology, and classification of seizures and epilepsies. This study aims to test the usefulness of this revised classification scheme on children with epilepsies aged between 0 and 18 years old. Of 527 patients, 75.1% only had 1 type of seizure and the commonest was focal seizure (61.9%). A specific electroclinical syndrome diagnosis could be made in 27.5%. Only 2.1% had a distinctive constellation. In this cohort, 46.9% had an underlying structural, metabolic, or genetic etiology. Among the important causes were pre-/perinatal insults, malformation of cortical development, intracranial infections, and neurocutaneous syndromes. However, 23.5% of the patients in our cohort were classified as having "epilepsies of unknown cause." The revised classification scheme is generally useful for pediatric patients. To make it more inclusive and clinically meaningful, some local customizations are required.

[Social aspects of epilepsy: marriage, pregnancy, driving, antiepileptic drug withdrawal and against social stigma].

2004-11-01

Persons with epilepsy need adequate advice and effective counselling about issues such as marriage, pregnancy, risks of inheriting epilepsy, driving, employment and antiepileptic drug withdrawal, because these persons are not receiving important information and education about their condition and possible adverse effects of treatment. Furthermore, women with epilepsy have increased rates of pregnancy complications and poor fetal outcomes including congenital malformations and developmental delay related to both their epilepsy and antiepileptic drugs. However, approximately 90% of all women with epilepsy undergo normal pregnancy and give birth to children free of birth defects. Pregnancy is generally safe in women with epilepsy. The study of long-term prognosis of childhood-onset epilepsy in Japan shows that the majority of these patients have lower levels of educational background as well as employment and marital status compared with the general population (Wakamoto H. et al). Of patients with epilepsy, 60% to 70% achieve control with antiepileptic medication. However, several antiepileptic drug withdrawal studies show variable rates of success, with relapse rates ranging from 12% to 63% (Britton J.W.). Driving is listed as major problem in persons with epilepsy. However, the patients with seizure-free more than two years have been able to get the driver's license since June, 2002. Social attitudes towards epilepsy cause more distress to the patient than the disease itself. We should realize that persons with epilepsy are normal or near-normal. To ameliorate the social stigma against epilepsy, continuous and repetitive educational efforts would be needed.

The abilities to identify facial expression from another person's face and to attribute mental states to others refer to preserved function of the temporal lobes. In the present study, we set out to evaluate emotion recognition and social cognition in presurgical and postsurgical patients with unilateral refractory temporal lobe epilepsy (TLE). The aim of our study was to investigate the effects of TLE surgery and to identify the main risk factors for impairment in these functions. We recruited 30 patients with TLE for longitudinal data analysis (14 with right-sided and 16 with left-sided TLE) and 74 patients for cross-sectional data analysis (37 with right-sided and 37 with left-sided TLE) plus 20 healthy controls. Besides standard neuropsychological assessment, we administered an analog of the Ekman and Friesen test and the Faux Pas Test to assess emotion recognition and social cognition, respectively. Both emotion recognition and social cognition were impaired in the group of patients with TLE, irrespective of the focus side, compared with healthy controls. The performance in both tests was strongly dependent on the intelligence level. Beyond intelligence level, earlier age at epilepsy onset, longer disease duration, and history of early childhood brain injury predicted social cognition problems in patients with TLE. Epilepsy surgery within the temporal lobe seems to have neutral effect on patients' performances in both domains. However, there are a few individual patients who appear to be at risk of postoperative decline, even when seizure freedom is achieved following epilepsy surgery. Copyright © 2014 Elsevier Inc.

2001-01-01

Full Text Available OBJECTIVE: To verify the effectiveness of the support group in the identification of family variables linked to epilepsy. METHOD: Pre-test were applied to parents of 21 children with benign epilepsy of childhood recently diagnosed, from 5 to 15 years, who participated in the groups at HC/Unicamp. There was a presentation of an educational video, discussion and application of the post-test 1. After six months, the post-test 2 was applied. RESULTS: The beliefs were: fear of swallowing the tongue during the seizures (76.19% and of a future mental disease (66.67%. Facing the epilepsy, fear and sadness appeared. 76.19% of the parents presented overprotection and 90.48%, expected a new seizure. In the post-test 1, the parents affirmed that the information offered had modified the beliefs. In the post-test 2, 80.95% didn't report great doubts about epilepsy and 90.48% considered their relationship with their children better. CONCLUSIONS: The demystification of beliefs supplied from the groups influenced the family positively, prevented behavior alterations and guaranteed effective care in the attendance to the child with epilepsy.

To determine if epilepsy surgery is effective in improving the quality of life (QOL) of children with intractable seizures using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The authors conducted a prospective study of the families of 35 children with intractable epilepsy who underwent epilepsy surgery. Parents completed the QOLCE preoperatively and again 6 to 18 months after surgery. At both assessment dates parents indicated the severity of their child's seizures during the past 6 months and the frequency of their child's seizures during the past 4 weeks on Likert-type scales. Children were split into two groups according to surgery outcome: seizure free vs persistent seizures. Statistical analyses were conducted to determine if children rendered seizure free showed a greater improvement in QOL compared to those with persistent seizures postoperatively. Greater improvement in QOL was documented for children rendered seizure free vs children with persistent seizures. This was significant for the overall QOLCE QOL score and subscales assessing cognitive, social, emotional, behavioral, and physical domains of life. Epilepsy surgery improves the quality of life of children rendered seizure free. Families can be counseled preoperatively of the potential benefits of surgery beyond seizure reduction.

Full Text Available This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.

The importance of consanguinity and its association with epilepsy has been suggested in some studies, but in one study the risk contributed to consanguinity for childhood epilepsy was not significanta. In the present study, there was an attempt to determine if consanguinity has any important association with epilepsy. All the epileptic children and adolescents up to the age of 18 years, who had been referred to Motahary Clinic in Shiraz, Iran, during a six-month period, were included in this cross-sectional study. The percentage of consanguinity in parents of the epileptic patients was compared to a sample of the general population in the same geographical area. In total, 181 unrelated epileptic children were included in this study. The mean age of these children was 7+/-4.6 years. The male/female ratio in these patients was 1.29. Overall, 61(33.7%) of the parents were first cousins (OR=2.264, 95%-CI: 1.618-3.169 in comparison to the general population), 37 (20.4%) were second cousins (OR=3.557, 95%-CI: 2.389-5.296), and 83 (45.9%) were not related. The percentage of consanguinity in parents of the epileptic patients was significantly higher in comparison to a sample of the general population (OR=2.612, 95%-CI: 1.929-3.536, Pmarriages (at least by 2.2 folds), as well as pre-marriage counseling for couples who have a family history of epilepsy are necessary as an effective preventive program.

Uncovering genomic causes of co-morbidity in epilepsy: gene-driven phenotypic characterization of rare microdeletions.

Directory of Open Access Journals (Sweden)

Dalia Kasperavičiūtė

Full Text Available Patients with epilepsy often suffer from other important conditions. The existence of such co-morbidities is frequently not recognized and their relationship with epilepsy usually remains unexplained.We describe three patients with common, sporadic, non-syndromic epilepsies in whom large genomic microdeletions were found during a study of genetic susceptibility to epilepsy. We performed detailed gene-driven clinical investigations in each patient. Disruption of the function of genes in the deleted regions can explain co-morbidities in these patients.Co-morbidities in patients with epilepsy can be part of a genomic abnormality even in the absence of (known congenital malformations or intellectual disabilities. Gene-driven phenotype examination can also reveal clinically significant unsuspected condition.

The epilepsy of Fyodor Mikhailovitch Dostoevsky (1821-1881).

Voskuil, P H

1983-12-01

Over 100 years ago, on the 27th of January 1881, Fyodor Mikhailovitch Dostoevsky died. Since that time, many biographies, monographs, memoirs, and, to a lesser extent, articles in the medical literature have discussed the fact that Dostoevsky was a patient with epilepsy. An attempt is made here to integrate the details of his illness into a medical case history, as we now do for every patient who visits a physician for the first time. The information pertinent to the case history includes: a description of all seizures, frequency of seizures, provocative factors, course of the disease, treatment, and family history. Even though we do not have the benefits of the results of electroencephalography (invented by Hans Berger in 1929), classification of the type of epilepsy Dostoevsky had is attempted. The existence or absence of the so-called ecstatic aura is crucial to such classification. Based on the data, it is likely that Dostoevsky suffered from partial complex epilepsy with secondarily generalized nocturnal seizures rather than primary generalized epilepsy.

Psychopathology in children and youth with epilepsy has previously been related to executive dysfunction, but the nature of the association is uncertain. We sought to explore risk factors for psychiatric disorders in children and youth with epilepsy, with emphasis on executive dysfunction, along with seizure-related and psychosocial factors. The cohort consisted of one hundred and one consecutive patients aged 10-19 years with focal (n=52) or genetic generalized (n=49) epilepsy. All were screened for psychiatric symptoms, using part of an extensive questionnaire, the Strengths and Difficulties Questionnaire (SDQ) for both patients and their parents. Participants scoring in the borderline or abnormal range on the SDQ received a psychiatric interview (Kiddie-SADS-PL). All participants underwent a neuropsychological examination, and those with general cognitive abilities (IQ)epilepsy-related or psychosocial factors were not significantly associated with psychiatric disorders. Multiple factors are associated with psychiatric problems in children and youth with epilepsy. In this study, executive dysfunction, male gender, and early epilepsy onset were independent risk factors for having a psychiatric disorder. An evaluation of psychiatric and cognitive problems is important to enable a positive long-term outcome in childhood epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

Epilepsy-Related Mortality is Low in Children: A 30 Year Population-Based Study in Olmsted County, MN

Nickels, Katherine C.; Grossardt, Brandon R.; Wirrell, Elaine C.

2013-01-01

Purpose Epilepsy is a common childhood neurologic disorder, affecting 0.5 to1% of children. Increased mortality occurs due to progression of underlying disease, seizure-related accidents, suicide, status epilepticus, aspiration during seizures, and sudden unexplained death in epilepsy (SUDEP). Previous studies show mortality rates of 2.7 to 6.9 per 1000 person-years (Berg et al., 2004, Sillanpaa & Shinnar, 2010). Potential risk factors include poor seizure control, intractable epilepsy, status epilepticus, tonic-clonic seizures, mental retardation, and remote symptomatic cause of epilepsy (Berg et al., 2004, Sillanpaa & Shinnar, 2010, Walczak et al., 2001). Few population-based studies of mortality and SUDEP in childhood-onset epilepsy have been published. The purpose of this study is to report mortality and SUDEP from a 30 year population-based cohort of children with epilepsy. Methods The Medical Diagnostic Index of the Rochester Epidemiology Project was searched for all codes related to seizure and convulsion in children living in Olmsted County, Minnesota and of ages birth through 17 years from 1980 through 2009. The medical records of these children were reviewed to identify all those with new-onset epilepsy, and to abstract other baseline and follow-up information. Potential risk factors including seizure type, epilepsy syndrome, history of status epilepticus, the presence and severity of neurologic impairment, and epilepsy outcome was reviewed. Epilepsy outcome was characterized by seizure frequency, number of anti-seizure medications (AEDs) used, and number of AEDs failed due to lack of efficacy, and epilepsy intractability at 1, 2, 3, 5, 10, 15, and 20 years after epilepsy onset. We followed all children through their most recent visit to determine vital status, cause of death, and whether autopsy was performed. Key Findings From 1980 to 2009, there were 467 children age birth through 17 years diagnosed with epilepsy while residents of Olmsted County, MN

To describe the phenomenology of monitored sudden unexpected death in epilepsy (SUDEP) occurring in the interictal period where death occurs without a seizure preceding it. We report a case series of monitored definite and probable SUDEP where no electroclinical evidence of underlying seizures was found preceding death. Three patients (two definite and one probable) had SUDEP. They had a typical high SUDEP risk profile with longstanding intractable epilepsy and frequent generalized tonic-clonic seizures (GTCS). All patients had varying patterns of respiratory and bradyarrhythmic cardiac dysfunction with profound electroencephalography (EEG) suppression. In two patients, patterns of cardiorespiratory failure were similar to those seen in some patients in the Mortality in Epilepsy Monitoring Units Study (MORTEMUS). SUDEP almost always occur postictally, after GTCS and less commonly after a partial seizure. Monitored SUDEP or near-SUDEP cases without a seizure have not yet been reported in literature. When nonmonitored SUDEP occurs in an ambulatory setting without an overt seizure, the absence of EEG information prevents the exclusion of a subtle seizure. These cases confirm the existence of nonseizure SUDEP; such deaths may not be prevented by seizure detection-based devices. SUDEP risk in patients with epilepsy may constitute a spectrum of susceptibility wherein some are relatively immune, death occurs in others with frequent GTCS with one episode of seizure ultimately proving fatal, while in others still, death may occur even in the absence of a seizure. We emphasize the heterogeneity of SUDEP phenomena. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

Definition and classification of epilepsy. Classification of epileptic seizures 2016

Directory of Open Access Journals (Sweden)

2017-01-01

Full Text Available Epilepsy is one of the most common neurological diseases, especially in childhood and adolescence. The incidence varies from 15 to 113 cases per 100 000 population with the maximum among children under 1 year old. The prevalence of epilepsy is high, ranging from 5 to 8 cases (in some regions – 10 cases per 1000 children under 15 years old. Classification of the disease has great importance for diagnosis, treatment and prognosis. The article presents a novel strategy for classification of epileptic seizures, developed in 2016. It contains a number of brand new concepts, including a very important one, saying that some seizures, previously considered as generalized or focal only, can be, in fact, both focal and generalized. They include tonic, atonic, myoclonic seizures and epileptic spasms. The term “secondarily generalized seizure” is replace by the term “bilateral tonic-clonic seizure” (as soon as it is not a separate type of epileptic seizures, and the term reflects the spread of discharge from any area of cerebral cortex and evolution of any types of focal seizures. International League Against Epilepsy recommends to abandon the term “pseudo-epileptic seizures” and replace it by the term “psychogenic non-epileptic seizures”. If a doctor is not sure that seizures have epileptic nature, the term “paroxysmal event” should be used without specifying the disease. The conception of childhood epileptic encephalopathies, developed within this novel classification project, is one of the most significant achievements, since in this case not only the seizures, but even epileptiform activity can induce severe disorders of higher mental functions. In addition to detailed description of the new strategy for classification of epileptic seizures, the article contains a comprehensive review of the existing principles of epilepsy and epileptic seizures classification.

Using a group of young healthy individuals and patients with multiple sclerosis (pMS), we aimed to investigate whether the physical attractiveness judgment affects perception of epilepsy. We tested hypothesis that subjects, in the absence of relevant clues, would catch upon the facial attractiveness when asked to speculate which person suffers epilepsy and select less attractive choices. Two photo-arrays (7 photos for each gender) selected from the Chicago Face Database (180 neutral faces of Caucasian volunteers with unknown medical status) were shown to study participants. Photos were evenly distributed along a continuum of attractiveness that was estimated by independent raters in prestudy stage. In each photo-array, three photos had rating 1-3 (unattractive), one photo had rating 4 (neutral), and three photos had rating 5-7 (attractive). High-quality printed photo-arrays were presented to test subjects, and they were asked to select one person from each photo-array "who has epilepsy". Finally, all subjects were asked to complete questionnaire of self-esteem and 19-item Scale of stereotypes toward people with epilepsy. In total, 71 students of psychology, anthropology, or andragogy (mean age: 21.6±1.7years; female: 85.9%) and 70 pMS (mean age: 37.9±8years; female: 71.4%) were tested. Majority of students or pMS had no previous personal experience with individuals with epilepsy (63.4%; 47.1%, p=0.052). Male photo was selected as epileptic in the following proportions: students - 84.5% unattractive, 8.5% neutral, and 7% attractive; pMS - 62.9% unattractive, 8.6% neutral, and 28.6% attractive (p=0.003). Female photo was selected as epileptic in the following proportions: students - 38% unattractive, 52.1% neutral, and 9.9% attractive; pMS - 32.9% unattractive, 34.3% neutral, and 32.9% attractive (0.003). Both groups showed very low potential for stigmatization: significantly lower in pMS in 10 items. Patients with multiple sclerosis showed significantly higher

We aimed to investigate the long-term seizure outcome of children and adolescents who were undergoing epilepsy surgery in the parietooccipital cortex and determine their predictive factors. We retrospectively analyzed the data of 50 consecutive patients aged 11.1 (mean) ± 5.1 (standard deviation) years at surgery. All patients but one had a magnetic resonance imaging (MRI)-visible lesion. Resections were parietal in 40%, occipital in 32%, and parietooccipital in 28% cases; 24% patients additionally underwent a resection of the posterior border of the temporal lobe. Etiology included focal cortical dysplasia in 44%, benign tumors (dysembryoplastic neuroepithelial tumor, ganglioglioma, angiocentric glioma, and pilocystic astrocytoma) in 32%, peri- or postnatal ischemic lesions in 16%, and tuberous sclerosis in 8% cases. At last follow-up (mean 8 years, range 1.5-18 years), 60% patients remained seizure-free (Engel class I): 30% had discontinued and 20% had reduced antiepileptic drugs. Most seizure recurrences (71%) occurred within the first 6 months, and only three patients presented with seizures ≥2 years after surgery. Independent predictors of seizure recurrence included left-sided as well as parietal epileptogenic zones and resections. Longer epilepsy duration to surgery was identified as the only modifiable independent predictor of seizure recurrence. Our study demonstrates that posterior cortex epilepsy surgery is highly effective in terms of lasting seizure control and antiepileptic drug cessation in selected pediatric candidates. Most importantly, our data supports the early consideration of surgical intervention in children and adolescents with refractory posterior cortex epilepsy.

Partial epilepsy is a very important problem of epileptology in childhood including clinical and therapeutic aspect especially surgery treatment. The aim of this study is to assess clinical value of neuroimagine techniques (structural MRI, MRI angiography) in partial epilepsy diagnostics in children. The relation between results of examinations with these methods and congenital and acquired risk factors related to partial epilepsy, age of its onset and clinical assessment of patients was analyzed. The study group consisted of 140 children with partial epilepsy hospitalized between 1998 and 2004 in Department of Pediatric Neurology, Collegium Medicum Jagiellonian University, Krakow. The group included 70 girls and 70 boys, the age ranged from 2 months to 17 years. In study group statistical analysis included different factors as which can be related with results of neuroimaging as age, load of pregnancy and birth period, familiar epilepsy, patient's risk factors for appearance of epilepsy, acquired risk factors of epilepsy, results of neurological examination, type of epilepsy, status epilepticus, and signs according epileptic attacks which can be related with neuroimaging results. The primary method of neuroimagine in all patients was structural MRI, in 16 cases Magnetic Resonance Angiography (MRA). The parametric tests (t-student), nonparametric Mann-Whitney's test were used in statistical analysis. The bilateral Fisher test was used to check rate in groups. There was assessed sensitivity, specificity, positive predictive value, negative predictive value; the 95% confidence interval was calculated for these parameters. Abnormalities in neurological examination in children with partial epilepsy were strongly correlated with MRI findings. The structural changes in MRI were found in younger children, whose course of epilepsy was longer than children without MRI changes. Changes in hippocampus ere the most common in children with partial epilepsy with abnormalities in

[Contemporary opinions on classification, pathogenesis and treatment of drug-resistant epilepsy].

Epilepsy is one of the most frequent neurological disorders, both in children and adult persons. About 0.5-1% of general population suffer from epilepsy, which means that about 50 million people in the world are affected. First years of life and very late adulthood are periods in human's life particularly predisposing to epilepsy. Repetitive epileptic seizures may cause many life-threatening situations and significantly lower patient's quality of life. To the most serious complications belong status epilepticus and sudden unexpected deaths due to epilepsy (SUDEP). Absences from work or school caused by seizures, difficulties in social life, frequent injuries and necessity of polytherapy are also important for patients. All these factors result in low self-esteem and poor quality of life. The main aim of the treatment was control of epileptic seizures. However, despite of new antiepileptic drugs developed almost every year, in one third of all patients with epilepsy seizures remain out of control. Those patients are regarded to have "drug-resistant epilepsy". Despite of significant scale of the problem, there is no one definition of the phenomenon. In the presented review the authors outline current definitions, recent opinions on pathogenesis and risk factors, and provide practical rules of pharmacotherapy of epilepsy, which should help to restrict drug-resistancy.

Epilepsy is a chronic disorder that is associated with numerous psychological challenges, especially in children. Drawings have been underutilized as a method to obtain insight into psychological issues in children with epilepsy. We asked 105 children with epilepsy, ages 5 to 18 years, to draw a picture of what it is like to have a seizure. Across ages and epilepsy syndromes, the drawings showed evidence of impaired self-concept, low self-esteem, and a sense of helplessness and vulnerability. Overall, the drawings of human figures were less developed than expected for chronological age. In some drawings, indicators of underlying depression were found. When considered by epilepsy syndrome or seizure type, some specific artistic features were noted. Children with simple partial (motor) seizures drew distorted body parts, especially limbs. Those with complex partial seizures depicted sensory symptoms and mental status changes such as confusion. Children with generalized tonic-clonic seizures showed shaking extremities. Drawings by children with absence seizures illustrated mainly staring. In conclusion, drawings are a powerful method to examine the self-concept of children with epilepsy and gain insight into their feelings about themselves and their world.

Full Text Available Introduction. The treatment of epilepsy is still a major challenge. Despite the introduction of many new antiepileptic drugs, approximately 30% of patients still remain drug resistant. In the absence of a satisfactory therapy outcome, which is sometimes associated with numerous side effects, there is a need for new and effective drugs with low toxicity. Cannabinoids have been shown in preliminary animal model studies and in studies of patients with epilepsy to have antiepileptic activity.

We have examined the value of prophylactic epilepsy surgery in diseases leading to intractable epilepsy. We reviewed 11 glioneuronal tumors (GNT) including gangliogliomas and dysembryoplastic neuroepithelial tumors, 11 cortical dysplasia (CD), and 33 cavernous angiomas (CA) diagnosed with MRI between the years 2000 and 2008 at the Department of Neurosurgery of Juntendo University in this study. We analyzed retrospectively the followings. Age of seizure onset and seizure severity. Region of each disease leading to intractable epilepsy. Seizure outcome after the surgery. Surgical morbidity. Ages of seizure onset of GNT, CD, and CA were 21.0±12.1, 1.3±7.5, 24.8±18.1 years, respectively. 81.8% of CD and GNT were intractable, however CA progresses to intractable epilepsy in 48.5%. The 66.7% of GNT with intractable seizures located in the mesial temporal lobe and 66.7% of CD had entra-temporal location. CA located in the mesial temporal lobe progressed to intractable epilepsy in 80%. Seizure free ratios of GNT, CD, and CA were 87.5%, 50.0%, 81.3%, respectively. In CDs where was impossible to carry out complete resection resulted in residual seizures. Neurological sequelae after surgery were observed in 3 cases. Morbidity ratios of motor weakness, speech difficulty, and memory disturbances are 4.6%, 4.6%, 2.3%, respectively. Majority of CD, GNT, and CA located in the mesial temporal lobe progress towards intractable epilepsy. Prophylactic epilepsy surgery by experienced surgeon with low complication rates can be an acceptable alternative for these pathological conditions. Seizure outcome of surgery for CD does not reach the success rates of those in GNT and CA. The cause of the unfavorable result in CD is the inapplicability to eloquent areas. Aggressive early surgery for CD may improve outcome considering neuronal plasticity of childhood. (author)

IQSEC2 is an X-linked gene associated with intellectual disability (ID) and epilepsy. Herein we characterize the epilepsy/epileptic encephalopathy of patients with IQSEC2 pathogenic variants. Forty-eight patients with IQSEC2 variants were identified worldwide through Medline search. Two patients were recruited from our early onset epileptic encephalopathy cohort and one patient from personal communication. The 18 patients who have epilepsy in addition to ID are the subject of this study. Information regarding the 18 patients was ascertained by questionnaire provided to the treating clinicians. Six affected individuals had an inherited IQSEC2 variant and 12 had a de novo one (male-to-female ratio, 12:6). The pathogenic variant types were as follows: missense (8), nonsense (5), frameshift (1), intragenic duplications (2), translocation (1), and insertion (1). An epileptic encephalopathy was diagnosed in 9 (50%) of 18 patients. Seizure onset ranged from 8 months to 4 years; seizure types included spasms, atonic, myoclonic, tonic, absence, focal seizures, and generalized tonic-clonic (GTC) seizures. The electroclinical syndromes could be defined in five patients: late-onset epileptic spasms (three) and Lennox-Gastaut or Lennox-Gastaut-like syndrome (two). Seizures were pharmacoresistant in all affected individuals with epileptic encephalopathy. The epilepsy in the other nine patients had a variable age at onset from infancy to 18 years; seizure types included GTC and absence seizures in the hereditary cases and GTC and focal seizures in de novo cases. Seizures were responsive to medical treatment in most cases. All 18 patients had moderate to profound intellectual disability. Developmental regression, autistic features, hypotonia, strabismus, and white matter changes on brain magnetic resonance imaging (MRI) were prominent features. The phenotypic spectrum of IQSEC2 disorders includes epilepsy and epileptic encephalopathy. Epileptic encephalopathy is a main clinical

Previous studies suggest a link between parental separation or divorce and risk of depression in adolescence. There are, however, few studies that have prospectively examined the effects of timing of biological father absence on risk for depressive symptoms in adolescence while controlling for a range of confounding factors. We examine the association between father absence occurring in early (the first 5 years) and middle childhood (5-10 years) and adolescent depressive symptoms in a sample comprising 5631 children from the UK-based Avon Longitudinal Study of Parents and Children (ALSPAC). Self-reported depressive symptoms at 14 years were assessed using the Short Mood and Feelings Questionnaire (SMFQ). Father absence was assessed from maternal questionnaires completed at regular intervals from the birth of the study child up to 10 years. There was evidence for an association between father absence in early childhood and increased odds of depressive symptoms at 14 years. This association was stronger in girls than in boys and remained after adjusting for a range of socio-economic, maternal and familial confounders assessed prior to the father's departure. Conversely, there was no evidence for an association between father absence in middle childhood and depressive symptoms at 14 years. Father absence in early childhood increases risk for adolescent depressive symptoms, particularly in girls. Future research should be aimed at identifying possible biological and psychosocial mechanisms linking father absence to depressive symptomatology to enable the development of family-based early prevention and intervention programmes targeting young children at risk.

Epilepsy in patients with Angelman syndrome

Directory of Open Access Journals (Sweden)

Fiumara Agata

2010-04-01

Full Text Available Abstract Angelman syndrome (AS is a neuro-behavioural, genetically determined condition, characterized by ataxic jerky movements, happy sociable disposition and unprovoked bouts of laughter in association with seizures, learning disabilities and language impairment. Most of the cases are hardly diagnosed during infancy as jerky movements, the cardinal sign, appear later in childhood. AS is caused by a variety of genetic mechanisms involving the 15q 11-13 chromosome. About 70% of cases are due to a "de novo" interstitial deletion in the long arm region, arising on the maternally inherited chromosome. The diagnosis is confirmed by methylation test or by mutation analysis of UBE3A gene. The deletion phenotype is generally linked to a more severe clinical picture in that 95% of patients manifest more severe seizures, severe mental and motor retardation, dysmorphic features and microcephaly. The pathogenesis of epilepsy in AS is still not fully understood. The presence in the commonly deleted region of a cluster of genes coding for 3 subunits of the GABAa receptor complex has lead to the hypothesis that GABA neurotransmission is involved. Epilepsy, often severe and hard to control, is present in 85% of patients within the first three years of life, although less than 25% develop seizures during the first year. It was observed that febrile seizures often precede the diagnosis. Most frequent types are atypical absences, generalized tonic-clonic, atonic or myoclonic seizures, with multiple seizure types occurring in 50% of deleted patients. There is still some doubt about the association with West syndrome. The EEG abnormalities are not themselves pathognomonic of AS and both background activity and epileptic discharges vary even in the same patient with time. Nevertheless, the existence of some suggestive patterns should facilitate the early diagnosis allowing the correct genetic counselling for the family. Some drugs seems to act better than others

Children with epilepsy are vulnerable to executive dysfunction, but the relationship between executive functioning (EF) and quality of life (QOL) in children with epilepsy is not fully delineated. This exploratory study elucidated the relationship between ecological EF and QOL in pediatric intractable epilepsy. Fifty-four consecutively referred pediatric epilepsy surgery candidates and their parents were administered IQ measures, the Behavior Rating Inventory of Executive Function (BRIEF), and the Quality of Life in Childhood Epilepsy (QOLCE) as part of a comprehensive neuropsychological evaluation. A significant difference was found in QOL between those with and without clinical impairments on the BRIEF [t(52)=3.93; p<.001]. That is, children with executive dysfunction had lower overall QOL. All seizure variables and BRIEF scales were associated with overall QOL [F(12, 40)=6.508; p=.001; R 2 =.661]. Working memory from the BRIEF was the most frequently elevated scale in our sample (57%). Those with executive dysfunction had 9.7 times the risk of having poor QOL. Poor EF control according to behavior ratings is significantly related to QOL in intractable pediatric epilepsy. Identification of executive dysfunction in home environments is an essential component of presurgical evaluations and target for intervention, which may improve QOL. Copyright © 2016 Elsevier Inc.

The aim of this qualitative study was to explore the challenges that parents of children with epilepsy experienced when engaging in dialog with their child about epilepsy and epilepsy-related issues. Using a qualitative exploratory approach, interviews were conducted with 34 parents of children with epilepsy (aged 6-16 years), consisting of 27 mothers and 7 fathers. Data were transcribed verbatim and thematically analyzed. Findings revealed five main themes: normalizing epilepsy, the invisibility of epilepsy, information concealment, fear of misinforming the child, and difficulty in discussing particular epilepsy-related issues. Many of the communicative challenges experienced by parents impacted on their ability to engage openly in parent-child dialog about epilepsy in the home. Parents face specific challenges when choosing to communicate with their child about epilepsy, relating to creating a sense of normality, reducing fear of causing their child worry, and having a lack of epilepsy-related knowledge. Healthcare professionals who work closely with families living with epilepsy should remain mindful of the importance of discussing family communication surrounding epilepsy and the challenges parents of children with epilepsy face when talking about epilepsy within the home.

Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management. Keywords: abdominal migraine, recurrent abdominal pain, abdominal epilepsy, cyclical vomiting

The medical students' knowledge about basic medical neuroscience in the preclinical level may be fragmented and incomplete. Evaluate the knowledge of students prior to a lecture on epilepsy in clinical level. One hundred ten fourth-year medical students' knowledge was accessed by a self-administered questionnaire. The presented results revealed that 91.8% of respondents knew that epilepsy arose from a transient dysfunction in the brain. Generalized tonic-clonic seizures (GTCs) were the most common type (91.5%) they knew and absence seizures were the least common type (33.6%) they knew. All of them knew that eating pork and punishment of gods did not cause epilepsy. However 50% thought that genetics was a cause and 80.3% did not know that stroke and sleep deprivation (92.7%) cause epilepsy. About treatment and prognosis, only 28.2% of respondents thought epilepsy can be cured and patients should take antiepileptic drugs (AEDs) for seizure free 2-5 years (48.2%), life long (33.6%). They knew that the patients should be prohibited from driving (80%), working on machinery (74.5%), and (27.3%) avoid drinking. However, they knew that the patients could marry (100%), get pregnant (98.2%), and lactate (91.9%). Regarding the first aid management, 50.9% of them recommended that placing a piece of wood between the teeth during a seizure and perform chest compressions (20.0%). Means knowledge scores is about 60%, the highest score is the definition of epilepsy (90.2%) and the lowest is type of seizure (43%). The findings indicated that lecturers should review aspects ofpathophysiology and emphasize on type of seizure, cause, consequences, and prognosis including first-aid management.

Catarina A. Guimarães

2014-03-01

Full Text Available In children with temporal lobe epilepsy (TLE, memory deficit is not so well understood as it is in adults. The aim of this study was to identify and describe memory deficits in children with symptomatic TLE, and to verify the influence of epilepsy variables on memory. We evaluated 25 children with TLE diagnosed on clinical, EEG and MRI findings. Twenty-five normal children were compared with the patients. All children underwent a neuropsychological assessment to estimate intellectual level, attention, visual perception, handedness, and memory processes (verbal and visual: short-term memory, learning, and delayed recall. The results allowed us to conclude: besides memory deficits, other neuropsychological disturbances may be found in children with TLE such as attention, even in the absence of overall cognitive deficit; the earlier onset of epilepsy, the worse verbal stimuli storage; mesial lesions correlate with impairment in memory storage stage while neocortical temporal lesions correlate with retrieval deficits.

This study aimed to compare the self-esteem of Brazilian adolescents with epilepsy and Brazilian adolescents without this condition and the correlations between self-esteem of these adolescents with depression and anxiety symptoms. Study participants were 101 adolescents of both sexes, aged 10-19years old, from elementary and high school education. Fifty patients diagnosed with uncomplicated epilepsy attending the pediatric epilepsy clinic of University Hospital composed the case group. The other fifty-one adolescents without this diagnosis were attending public schools in Campinas-SP region. The instruments used were: identification card with demographics and epilepsy data, Multidimensional Self-Esteem Scale, Beck Depression Inventory and Inventory of State-Trait Anxiety - IDATE. A statistically significant result was found in the Responsibility Self-esteem Dimension favoring the control group. Significant correlations between self-esteem scores and anxiety and depression symptoms were also found. The development of a chronic disease such as epilepsy leads to a change in the way the individual perceives himself and the social environment he is inserted, influencing his behavior. The way people with epilepsy experience their seizures is a subjective measure that will control his/her well-being. Childhood and adolescence form the basis for a healthy emotional development; thus, our results show the importance of studying how subjective variables relate to the physical aspects of a chronic disease in these life stages.

BACKGROUND: The ketogenic diet (KD) is an established, effective non-pharmacologic treatment for drug resistant childhood epilepsy. For a long time, the KD was not recommended for use in infancy (under the age of 2 years) because this is such a crucial period in development and the perceived high risk of nutritional inadequacies. Indeed, infants are a vulnerable population with specific nutritional requirements. But current research shows that the KD is highly effective and well tolerated in ...

Rapid advances in genetic research and increased use of genetic testing have increased the emphasis on genetic causes of epilepsy in patient encounters. Research in other disorders suggests that genetic causal attributions can influence patients' psychological responses and coping strategies, but little is known about how epilepsy patients and their relatives will respond to genetic attributions of epilepsy. We investigated the possibility that among members of families containing multiple individuals with epilepsy, depression, the most frequent psychiatric comorbidity in the epilepsies, might be related to the perception that epilepsy has a genetic cause. A self-administered survey was completed by 417 individuals in 104 families averaging 4 individuals with epilepsy per family. Current depression was measured with the Patient Health Questionnaire. Genetic causal attribution was assessed by three questions addressing the following: perceived likelihood of having an epilepsy-related mutation, perceived role of genetics in causing epilepsy in the family, and (in individuals with epilepsy) perceived influence of genetics in causing the individual's epilepsy. Relatives without epilepsy were asked about their perceived chance of developing epilepsy in the future, compared with the average person. Prevalence of current depression was 14.8% in 182 individuals with epilepsy, 6.5% in 184 biologic relatives without epilepsy, and 3.9% in 51 individuals married into the families. Among individuals with epilepsy, depression was unrelated to genetic attribution. Among biologic relatives without epilepsy, however, prevalence of depression increased with increasing perceived chance of having an epilepsy-related mutation (p = 0.02). This association was not mediated by perceived future epilepsy risk among relatives without epilepsy. Depression is associated with perceived likelihood of carrying an epilepsy-related mutation among individuals without epilepsy in families containing

Magnetic resonance imaging (MRI), single photon emission tomography (SPET), and positron emission tomography (PET) using [18F]fluorodeoxyglucose were used in combination with scalp and scalp-video EEGs in a group of 30 pediatric patients with drug resistant epilepsy (DRE) in order to identify patients who could benefit from neurosurgical approach. Seizures were classified according to the consensus criteria of The International League Against Epilepsy. In three patients infantile spasms (IS) were diagnosed; 13 subjects were affected by different types of generalized seizures, associated with complex partial seizures (CPS) in three. In the other 14 patients partial seizures, either simple (SPS) or complex, were present. A localized abnormality was demonstrated in one patient with IS and in three patients with generalized seizures. Of the group of 14 subjects with CPS, MRI and CT were normal in 7, but SPET or PET indicated focal hypoperfusion or hypometabolism concordant with the localization of the EEG abnormalities. In 5 of the other 7 patients anatomical and functional imaging and EEG findings were concordant for a localized abnormality. It can be concluded that functional imaging combined with scalp EEGs appears to be superior to the use of only CT and MRI for selecting children with epilepsy in whom a surgical approach can be considered, in particular when CPS resistant to therapy are present.

When a child is diagnosed with epilepsy, not only has the child's life been disrupted but also the family's sense of normalcy. Although there is considerable literature discussing family concerns and social support issues in families with chronically ill children, a major gap lies in the exploration of how the specifics of childhood epilepsy affect parents and family operations. The purpose of this study was to identify psychosocial care needs of parents of children with epilepsy. Utilizing the Family Systems Nursing theory as a framework, this correlation study examined the relationships among social and community support, family needs, family empowerment, and family quality of life in 29 primary caregivers of a child with epilepsy. These families felt highly supported; they had low needs and high perceptions of empowerment. There was a negative association between social supports and the total family needs survey scale and the subscales of financial support, help regarding explaining to others, and professional support. There was no association between family empowerment or quality of life with parental perceptions of social support. In general, as parental perceptions of family needs increased, perceptions of familial social supports decreased. Further research is recommended to investigate varying socioeconomic status effects in families with children with pediatric epilepsy.

Background Mutations in the KIAA2022 gene have been reported in male patients with X-linked intellectual disability, and related female carriers were unaffected. Here, we report 14 female patients who carry a heterozygous de novo KIAA2022 mutation and share a phenotype characterised by intellectual disability and epilepsy. Methods Reported females were selected for genetic testing because of substantial developmental problems and/or epilepsy. X-inactivation and expression studies were performed when possible. Results All mutations were predicted to result in a frameshift or premature stop. 12 out of 14 patients had intractable epilepsy with myoclonic and/or absence seizures, and generalised in 11. Thirteen patients had mild to severe intellectual disability. This female phenotype partially overlaps with the reported male phenotype which consists of more severe intellectual disability, microcephaly, growth retardation, facial dysmorphisms and, less frequently, epilepsy. One female patient showed completely skewed X-inactivation, complete absence of RNA expression in blood and a phenotype similar to male patients. In the six other tested patients, X-inactivation was random, confirmed by a non-significant twofold to threefold decrease of RNA expression in blood, consistent with the expected mosaicism between cells expressing mutant or normal KIAA2022 alleles. Conclusions Heterozygous loss of KIAA2022 expression is a cause of intellectual disability in females. Compared with its hemizygous male counterpart, the heterozygous female disease has less severe intellectual disability, but is more often associated with a severe and intractable myoclonic epilepsy.

The current study aimed to evaluate the clinical characteristics and outcome of hemispherotomy in children with refractory hemispherical epilepsy. Retrospective analysis of data in twenty one children aged ≤12 years who underwent hemispherotomy and had at least two years post surgery follow-up was performed. Sixteen children underwent Delalande's vertical para-sagittal hemispherotomy (VPH), while lateral peri-insular functional hemispherotomy was performed in the rest. The average age of onset for epilepsy in the study population was 2.9 ± 2.4 years; the average duration of epilepsy was 4.0 ± 2.9 years. The mean age at surgery of the study population was 6.8 ± 2.8 years. Six (28.5%) children were girls. Gliosis due to presumed childhood infarct was most common etiology, observed in 13 (62.0%) of the children, followed by Rasmussen's encephalitis in six (28.5%). There was no significant difference between the surgery groups for the reported acute post operative seizures (APOS) (20.0% vs. 25.0%; p = 1.000). At last follow up 90.5% patients were seizure free; there was no difference between the groups for seizure freedom (60.0% vs. 87.5%; p = 0.228). When analyzed for outcome between the etiologies, seizure freedom was similar for gliosis due to infarct (76.9%), Rassmussens encephalitis (83.3%) and malformations of cortical development (MCD) (100.0%). Moreover, improved quality of life in epilepsy (QOLIE) scores was observed in 80.0% of the lateral peri-insular functional hemispherotomy group and 87.5% children in VPH group at the last follow-up. Gliosis due to presumed childhood infarct was the leading cause of medically refractory epilepsy caused by hemispheric lesions in the current study. Encouragingly, hemispherotomy offers seizure freedom (in 90.5% patients) and improvement in QOLIE scores at two years follow up. Copyright © 2015 IJS Publishing Group Ltd. Published by Elsevier Ltd.

To evaluate measures of epilepsy-specific impact currently available for use with children and adolescents. The relative merits of the different measures are examined. Four published epilepsy-specific impact measures, the Epilepsy and Learning Disabilities Quality of Life Scale (ELDQOL), the Health-related Quality of Life in Children with Epilepsy (HRQoLCE); the Impact of Childhood Neurologic Disability Scale (ICND), the Quality of Life in Epilepsy Inventory for Adolescents (QOLIE-AD-48), and the Quality of Life for Children with Epilepsy (QOLCE) were reviewed. There exist several shortcomings with the available measures on various psychometric criteria with not one of the currently available measures reaching acceptable psychometric standards in terms of reliability and validity. Of note are the particular inadequacies in the validation of scale content; with there being no investigation of the existence of age or ability effects for the items in any of the questionnaires reviewed. There is a clear demand for a psychometrically robust measure of subjective impact of epilepsy for children and adolescents, which is applicable to a wide age and ability range. At present, the efforts of the Canadian Pediatric Epilepsy Network with the recent publication of a novel measure holds much promise for the future. It is advocated that further efforts are made to further establish the psychometric properties of these scales and for their integration within a comprehensive outcome model for use in the evaluation of clinical interventions.

To assess the role of resective brain surgery in childhood epilepsy. We retrospectively analysed the seizure outcomes in 55 children with epilepsy who had resective brain surgery between 1997 and 2012, at our centre. The children were 1.5-18 years at the time of surgery; their seizure onset was between 0.2 andto 15 years of age. 48 had refractory epilepsy. One child died of tumour progression. Follow-up duration in the survivors ranged from 2 to -16 years (mean: 9).Presurgical evaluation included clinical profiles, non-invasive V-EEG monitoring, neuroimaging with MRIs in all; SPECT and PET in selected patients. 54 had intraoperative ECoG. An Engel Class 1 outcome was seen in 78% of the cohort, with 67% being off all AEDs at the most recent follow-up. Children with tumours constituted the majority (56%), with 87% of this group showing a Class 1 outcome and 84% being off AEDs. Children with cortical dysplasia had a Class 1 outcome in 56%. Resective brain surgery is an efficacious option in some children with epilepsy. We found ECoG useful to tailor the cortical resection and in our opinion ECoG contributed to the good seizure outcomes. Copyright © 2015 European Paediatric Neurology Society.

The objective of this study was to examine the association between convulsive status epilepticus (CSE) and health-related quality of life (HRQL) during a 24-month follow-up in a multisite incident cohort of children with epilepsy. Data were collected in the Health-Related Quality of Life Study in Children with Epilepsy Study from 374 families of children with newly diagnosed epilepsy. The Quality of Life in Childhood Epilepsy (QOLCE) Questionnaire was used to evaluate parent-reported child HRQL. Hierarchical linear regression was used to examine the relationship between CSE and HRQL at 24 months postepilepsy. A total of 359 families completed the 24-month assessment. Twenty-two children (6.1%) had experienced CSE during the follow-up. Children with and without CSE were similar, except a larger proportion of children with CSE had partial seizures (p QOLCE scores. The findings suggested that not only do children with CSE have significantly poorer HRQL compared with their non-CSE counterparts, but that this factor is independent of the effects of demographic and clinical features known to affect HRQL. © 2014 American Academy of Neurology.

Panayiotopoulos syndrome (PS) is an age-related seizure susceptibility syndrome that affects the central autonomic system. Although the majority of the few ictal recordings obtained so far suggest an occipital origin, semiological and interictal EEG data appear to favour more extensive involvement. In this study, the characteristics (including those based on semiology and EEG) of children with Panayiotopoulos syndrome (n=24) and those with lesion-related, symptomatic occipital lobe epilepsy (SOLE) (n=23) were compared. Detailed semiological information and EEG parameters including the localisation, distribution, density (n/sec), reactivity, and morphological characteristics of spike-wave foci and their relationship with different states of vigilance were compared between the two groups. The age at seizure onset was significantly younger in patients with symptomatic occipital lobe epilepsy than in those with PS (mean age at onset: 3.4 versus 5.6 years, respectively; p=0.044). Autonomic seizures (p=0.001) and ictal syncope (p=0.055) were more frequent in PS than in symptomatic occipital lobe epilepsy (87.5% and 37.5% versus 43.5% and 13%, respectively). The interictal spike-wave activity increased significantly during non-rapid eye movement (non-REM) sleep in both groups. The spike waves in non-REM seen in PS tended to spread mainly to central and centro-temporal regions. The results indicate that although common features do exist, Panayiotopoulos syndrome differs from symptomatic occipital lobe epilepsy and has a unique low epileptogenic threshold related to particular brain circuits.

The idiosyncratic aspects of the epilepsy of Fyodor Dostoevsky.

Science.gov (United States)

Hughes, John R

2005-11-01

The goal of this article is to review the idiosyncratic aspects of the epilepsy of Fyodor Dostoevsky, one of the greatest writers of all time. The onset of his seizures is controversial, with some evidence pointing to his childhood and other reports that would place the onset in his teens or his twenties. His life in prison in Siberia and then in the Russian army is reviewed. His lifestyle included many factors that exacerbated his epilepsy, especially stress and sleep deprivation. His compulsion for gambling played an important role in producing great stress in his life, as he tried to reverse his poverty in the casinos. The most idiosyncratic aspect of his epilepsy was his so-called ecstatic aura. The etiology of his seizures was probably inherited as revealed by the seizures of his father and the status epilepticus and death of his young son. This great writer died from lung hemorrhages in 1891. Discussed in this review is that he did not likely have an aura of ecstasy; only a few such possible cases can be found in the world literature. For those few cases, evidence from electrical self-stimulation studies in animals and humans, investigating "pleasure centers," can be found to involve the limbic system, especially the septal nucleus. Data from the human amygdala provide evidence why almost all auras are, in fact, unpleasant and not pleasant. A review of recent data on the risks to offspring of epileptic fathers confirms that the etiology of Dostoevsky's epilepsy was probably inherited and that he probably had an idiopathic generalized epilepsy with minor involvement of the temporal lobe. A relationship is seen between his severe obsession with gambling and his epilepsy. Finally, Fyodor Dostoevsky is an excellent example of the "temporal lobe personality."

Statistical parametric mapping (SPM) quantification and analysis has been successfully applied to functional imaging studies of partial epilepsy syndromes in adults. The present study evaluated whether localisation of the epileptogenic zone (determined by SPM) improves upon visually examined single-photon emission tomography (SPET) imaging in presurgical assessment of children with temporal lobe epilepsy (TLE) and frontal lobe epilepsy (FLE). The patient sample consisted of 24 children (15 males) aged 2.1-17.8 years (9.8±4.3 years; mean±SD) with intractable TLE or FLE. SPET imaging was acquired routinely in presurgical evaluation. All patient images were transformed into the standard stereotactic space of the adult SPM SPET template prior to SPM statistical analysis. Individual patient images were contrasted with an adult control group of 22 healthy adult females. Resultant statistical parametric maps were rendered over the SPM canonical magnetic resonance imaging (MRI). Two corresponding sets of ictal and interictal SPM and SPET images were then generated for each patient. Experienced clinicians independently reviewed the image sets, blinded to clinical details. Concordance of the reports between SPM and SPET images, syndrome classification and MRI abnormality was studied. A fair level of inter-rater reliability (kappa=0.73) was evident for SPM localisation. SPM was concordant with SPET in 71% of all patients, the majority of the discordance being from the FLE group. SPM and SPET localisation were concordant with epilepsy syndrome in 80% of the TLE cases. Concordant localisation to syndrome was worse for both SPM (33%) and SPET (44%) in the FLE group. Data from a small sample of patients with varied focal structural pathologies suggested that SPM performed poorly relative to SPET in these cases. Concordance of SPM and SPET with syndrome was lower in patients younger than 6 years than in those aged 6 years and above. SPM is effective in localising the potential

Epilepsy represents the third most common neurological disorders in the elderly after cerebrovascular disorders and dementias. The incidence of new-onset epilepsy peaks in this age group. The most peculiar aetiologies of late-onset epilepsy are stroke, dementia, and brain tumours. However, aetiology remains unknown in about half of the patients. Diagnosis of epilepsy may be challenging due to the frequent absence of ocular witnesses and the high prevalence of seizure-mimics (i.e. transient ischemic attacks, syncope, transient global amnesia or vertigo) in the elderly. The diagnostic difficulties are even greater when patients have cognitive impairment or cardiac diseases. The management of late-onset epilepsy deserves special considerations. The elderly can reach seizure control with low antiepileptic drugs (AEDs) doses, and seizure-freedom is possible in the vast majority of patients. Pharmacological management should take into account pharmacokinetics and pharmacodynamics of AEDs and the frequent occurrence of comorbidities and polytherapy in this age group. Evidences from double-blind and open-label studies indicate lamotrigine, levetiracetam and controlled-release carbamazepine as first line treatment in late-onset epilepsy.

Current position of phenobarbital in epilepsy and its future.

Brodie, Martin J; Kwan, Patrick

2012-12-01

This article reviews the current position of phenobarbital using articles published since 2000 and speculates on its likely future contribution to epilepsy care. Over the last decade there have been no major double-blind randomized placebo-controlled or comparative trials with phenobarbital. Previous studies have suggested that phenobarbital is as effective in monotherapy as phenytoin and carbamazepine. Several observational studies undertaken in developing countries over the last decade have confirmed its efficacy and safety for the common epilepsies. This was particularly so in the substantial demonstration project undertaken in rural China under the auspices of the World Health Organization in partnership with the International League Against Epilepsy and International Bureau for Epilepsy. Phenobarbital is still widely used for neonatal and childhood seizures and for drug-resistant convulsive and nonconvulsive status epilepticus. Recent data have confirmed in a prospective cohort of women taking phenobarbital as monotherapy that the drug can be associated with a range of congenital defects in exposed infants. Much effort has gone into exploring the apparent contradiction of higher withdrawal rates due to cognitive and behavioral side effects in studies undertaken in developed countries but not in those sited in the developing world. A raft of data over the last 10 years, including a systematic review, showed no important differences between the tolerability of phenobarbital compared to that with other antiepileptic drugs. Finally, cognitive test scores and mood ratings in 136 people with epilepsy receiving phenobarbital for a year were similar to those in 137 age-, sex-, and education-matched controls in a number of Chinese villages. Indeed, there were some cognitive gains in the patients possibly due to improved seizure control. Phenobarbital is still the most cost-effective pharmacologic treatment for epilepsy. All these data predict a healthy future for

Childhood epilepsy not only significantly impacts a child's social relationships and psychosocial wellbeing, but it can also cause disruptions in family relations. Children living with epilepsy often rely on parental figures for guidance in relation to their condition. A paucity of research has examined the challenges for children when communicating about epilepsy with parental figures. This qualitative study explored the challenges faced by children when talking about epilepsy with their parent(s). Semi-structured interviews were conducted with 29 children (aged 6-16 years) living with epilepsy. Participants were recruited from a neurology department of a major pediatric hospital and from a national epilepsy association. Interviews were transcribed verbatim and thematically analyzed. Findings revealed four themes: communication impeding normalcy, parental overprotection, parental reactions to epilepsy-related communication, and restriction of activities as a consequence of epilepsy-related communication. The study highlights the need for a greater understanding of parent-child dialogue surrounding epilepsy and where challenges lie for children in conversing about their condition. Parents and health care professionals play a pivotal role in facilitating an environment where children feel comfortable talking about epilepsy. This information will be instrumental in the development of a communication-based intervention for families living with epilepsy. © The Author(s) 2016.

Startle epilepsy is a syndrome of reflex epilepsy in which the seizures are precipitated by a sudden and surprising, usually auditory, stimulus. We describe herein a girl who had been suffering with startle-induced seizures since 2 years of age. She had focal, tonic and tonic-clonic seizures, refractory to antiepileptic treatment. Daily tonic seizures led to very frequent falls and morbidity. Neurologically, she had no deficit. Interictal EEG showed slow waves and epileptiform discharges in central and fronto-central regions. Video-polygraphic recordings of seizures, triggered by stimuli, showed generalised symmetric tonic posturing with ictal EEG, characterised by an abrupt and diffuse electrodecremental pattern of fast activity, followed by alpha-theta rhythm superimposed by epileptic discharges predominantly over the vertex and anterior regions. Magnetic resonance imaging showed no abnormalities. Corpus callosotomy was performed when the patient was 17. Since surgery, the patient (one year follow-up) has remained seizure-free. Corpus callosotomy may be considered in patients with startle epilepsy and tonic seizures, in the absence of focal lesions amenable to surgery. [Published with video sequences].

Children and youth with epilepsy have long been subjected to excessive restrictions on extracurricular activities due to concerns over risk of injury. Over time physicians and medical regulatory associations have liberalized the advice given for people with epilepsy to promote independence, self-esteem and general health benefits of physical activity. Current evidence suggests that few restrictions are needed for children with epilepsy beyond water-related precautions and avoidance of very high-risk activities. However, more stringent restrictions on daily activities may be imposed by caregivers. This study was aimed at exploring current perceptions of parents regarding restrictions on activity for children with epilepsy and the child's perspective on restrictions related to the diagnosis. A self-administered questionnaire was offered to a sample of parent-child dyads of children/youth with epilepsy attending summer camp for children with epilepsy age 8-18years. A 10-item validated HARCES Parent Scale of Childhood Epilepsy was completed by the parent/guardian and a modified-HARCES completed by the child. The primary objective was to assess the degree of restrictions placed on children with epilepsy from the perspective of child and parent assessed independently. Agreement of perceived restrictions between parent-child dyads was also determined. 21 parent/guardian-child pairs were recruited with mean age of children/youth 12.7years (range 9-16years). Total HARCES scores for parents and guardians ranged from 11-26 (x=16.5; SD 4.9) while total scores for children with epilepsy similarly ranged from 10-25 (x=15.2; SD 4.9). There were no differences in total parent scores when analyzed by child's age (13years), gender, age of seizure onset, seizure frequency or seizure type. Total HARCES scores showed no agreement between parent and child pairs with correlation of 0.2798 (95% CI -0.173-0.635). Children and youth with epilepsy often face activity restrictions based on

The Managing Epilepsy Well (MEW) Network was established in 2007 by the Centers for Disease Control and Prevention Epilepsy Program to expand epilepsy self-management research. The network has employed collaborative research strategies to develop, test, and disseminate evidence-based, community-based, and e-Health interventions (e-Tools) for epilepsy self-management for people with epilepsy, caregivers, and health-care providers. Since its inception, MEW Network collaborators have conducted formative studies (n=7) investigating the potential of e-Health to support epilepsy self-management and intervention studies evaluating e-Tools (n=5). The MEW e-Tools (the MEW website, WebEase, UPLIFT, MINDSET, and PEARLS online training) and affiliated e-Tools (Texting 4 Control) are designed to complement self-management practices in each phase of the epilepsy care continuum. These tools exemplify a concerted research agenda, shared methodological principles and models for epilepsy self-management, and a communal knowledge base for implementing e-Health to improve quality of life for people with epilepsy. © 2013.

A CLINICAL CASE OF SYNGAP1 GENE MUTATION IN A GIRL WITH EPILEPSY, MENTAL RETARDATION, AUTISM, AND MOTOR DISORDERS

Full Text Available The introduction of the latest genetic techniques into practice could discover a basis for the comorbidity of genetic epilepsies and behavioral disturbances with cognitive impairments. Some chromosomal syndromes are characterized by a specific electroencephalogram (EEG pattern, the type of seizures, and the variant of the course of epilepsy. This paper describes a case of synaptic RAS GTP-ase-activating protein 1 (SYNGAP1 gene mutation in a 9-year-old female patient with eyelid myoclonic epilepsy, atypical absences, and atypical autism with mental retardation. The patient’s parents visited a physician for epilepsy (myoclonic absences, markedly delayed psycho-speech development, and specific communication problems in the child. The characteristics of autistic behavior were manifested from birth; routine EEG recorded epileptiform activity at the age of 2 years; epileptic seizures appeared at 5 years. Valproic acid and levetiracetam in this patient exerted a good effect on seizures; however, a clinical and encephalographic remission was achieved by a combination of levetiracetam and ethosuximide. The clinical case including the neurological and psychic statuses, logopedic characteristics, the result of psychological testing, and video-EEG monitoring findings are analyzed in detail.The SYNGAP1 gene is located on chromosome 6p21.3. About 50 cases of SYNGAP1 syndrome are now known worldwide. After normal maternal pregnancy and delivery, the patients show delayed psychomotor development with pronounced regression at 1 to 3 years of age. At this age, there are diffuse polyspike discharges on the EEG or an onset of generalized epileptic seizures (atonic, myoclonic, eyelid myoclonic, and absence seizures, commonly photosensitivity and autoinduction, mental development stops, speech regresses, behavioral disorders that are typical of autism develop. Drug-resistant epilepsy is noted in approximately half of the described cases. There is a correlation

The history of eponyms for epilepsy in the lands of the Eastern globe present the portrait of the attitudes of both the laymen and skilled people towards the disease and patient, as well as to the Nature itself. As opposed to the West which during the Middle ages changed its concepts of epilepsy as the organic brain disease for the sublime 'alchemic' position, the people of the East were more prone to consider from the beginning of their civilization till the XIX century that epilepsy is the consequence of the evanescent spiritual and extracorporal forces which by themselves were out of their reach. As compared to the western civilization, the historical resources are, often as a consequence of a linguistic barriers, more scarce-as consequently is the number of eponyms, but are nevertheless picturesque. The medical science from Babylonian period presumed that epileptic manifestations are the consequence of the demonic or ill spiritual actions. There existed an attitude that at the beginning of an epileptic attack the patient was possessed by a demon (the Akkadic, i.e., Babylonian verb "sibtu" denoting epilepsy, had the meaning "to seize" or "to be obsessed"); at the end of the clonic phase the demon departed from the body. Different demons were responsible for different forms of epilepsy such as nocturnal and children epilepsy, absence epilepsy and pure convulsions, simple and complex automatisms, and gelastic epilepsy. Thus, the doctors from the period of Babylon aside from making primordial classification of epilepsies, knew about their clinical picture (prodromal symptoms and aura, Jackson's epilepsy. Todd's paralysis), postictal phenomena and intericatl emotional instability; provocative factors were also known (sleep deprivation, emotions, as well as alcohol, albeit in a negative sense-as a cure for epilepsy). There is no doubt than in the period of Babylon the clinical picture of serial fits and its progress to status epilepticus were clearly recognized and

The purpose of this study was to examine: 1) the course of perceived epilepsy-related stigma among children newly-diagnosed with epilepsy (n=39) and their caregivers (n=97) over a two year period, 2) the influence of seizure absence/presence on children and caregivers’ perception of epilepsy-related stigma, and 3) congruence of child and caregiver perception of child epilepsy-related stigma. Participants completed a measure of perceived epilepsy-related stigma at three time points, and seizure status was collected at the final time point. Results indicated both caregivers (t1,76 = − 2.57 pstigma from diagnosis to two years post-diagnosis. No significant differences were found in caregiver and child report of perceived stigma for children experiencing seizures as compared to children who have been seizure-free for the past year. Results revealed poor caregiver-child agreement of perceived epilepsy-related stigma at all three time points. These data suggest that while children with epilepsy initially perceive epilepsy-related stigma at diagnosis, their perception of stigma decreases over time. Having a better understanding of the course of epilepsy-related stigma provides clinicians with information regarding critical times to support families with stigma reduction interventions.

Importance Valproate is used for the treatment of epilepsy and other neuropsychological disorders and may be the only treatment option for women of childbearing potential. However, prenatal exposure to valproate may increase the risk of autism. Objective To determine whether prenatal exposure to valproate is associated with an increased risk of autism in offspring. Design, Setting, and Participants Population-based study of all children born alive in Denmark from 1996 to 2006. National registers were used to identify children exposed to valproate during pregnancy and diagnosed with autism spectrum disorders (childhood autism [autistic disorder], Asperger syndrome, atypical autism, and other or unspecified pervasive developmental disorders). We analyzed the risks associated with all autism spectrum disorders as well as childhood autism. Data were analyzed by Cox regression adjusting for potential confounders (maternal age at conception, paternal age at conception, parental psychiatric history, gestational age, birth weight, sex, congenital malformations, and parity). Children were followed up from birth until the day of autism spectrum disorder diagnosis, death, emigration, or December 31, 2010, whichever came first. Main Outcomes and Measures Absolute risk (cumulative incidence) and the hazard ratio (HR) of autism spectrum disorder and childhood autism in children after exposure to valproate in pregnancy. Results Of 655 615 children born from 1996 through 2006, 5437 were identified with autism spectrum disorder, including 2067 with childhood autism. The mean age of the children at end of follow-up was 8.84 years (range, 4-14; median, 8.85). The estimated absolute risk after 14 years of follow-up was 1.53% (95% CI, 1.47%- 1.58%) for autism spectrum disorder and 0.48% (95% CI, 0.46%-0.51%) for childhood autism. Overall, the 508 children exposed to valproate had an absolute risk of 4.42% (95% CI, 2.59%-7.46%) for autism spectrum disorder (adjusted HR, 2.9 [95% CI, 1

The mechanisms of the ketogenic diet remain unclear, but several predictors of response have been proposed. We aimed is to study the relationship between the etiology of epilepsy, cerebrospinal fluid neurotransmitters, pterins, and amino acids, and response to a ketogenic diet. We studied 60 patients who began classic ketogenic diet treatment for refractory epilepsy. In 24 of 60 individuals, we analyzed cerebrospinal fluid neurotransmitters, pterins, and amino acids in baseline conditions. Mean age at epilepsy onset was 24 months, 83.3% were focal epilepsies, and in 51.7% the etiology of the epilepsy was unknown. Six months after initiating the ketogenic diet, it was effective (greater than a 50% reduction in seizure frequency) in 31.6% of patients. We did not find a link between rate of efficacy for the ketogenic diet and etiologies of epilepsy, nor did we find a link between the rate of efficacy for the ketogenic diet and cerebrospinal fluid pterins and biogenic amines concentrations. However, we found statistically significant differences for lysine and arginine values in the cerebrospinal fluid between ketogenic diet responders and nonresponders, but not for the other amino acids analyzed. The values of some amino acids were significantly different in relationship with the ketogenic diet efficacy; however, the epilepsy etiology and the cerebrospinal fluid biogenic amine and pterin values were not.

Full Text Available The epilepsy treatment is to be based on existing general principles and standards of therapy with differential approach to each patient. Besides peculiarities of treatment of different types of seizures and forms of epilepsy there are also differential approaches to special groups of patients. To one of such groups are referred to women of reproductive age. These patients are referred to special group of risk due to the development of certain side effects of antiepileptic drugs (АED. This article focuses in details on peculiarities of treatment of women of reproductive age with epilepsy with accent made on tolerability and safety of the antiepileptic therapy. It is necessary to take into consideration, that at women neuroendocrinal disorders can be caused both by the disease itself – epilepsy (in such case disorders depend on the starting age, form of epilepsy, focal localization, duration of disorder and other factors, referred to the disease, as well as by the undertaken therapy. The articlehereunder considers only issues, referred to the treatment, i. e. AED side effects and its input in the decrease of life quality of women with epilepsy. As women’s reproductive function starts forming long ago before childbearing age, it is necessary for this category to comprise not only women and adolescents, but girls as well. Notwithstanding the fact that so called benign forms of epilepsy pass before the pubescence period (idiopathic focal epilepsies, several forms of idiopathic generalized epilepsy, in many cases the epilepsy, which has started in childhood, continues in the adult age as well. In the same time there can be possible remote negative consequences of the antiepileptic therapy, which can show at a woman of a reproductive age. The data, given in the article, witnesses the need of the right AED selection at women of reproductive age, suffering from epilepsy. The AED should be selected not only depending on the form of the

The origin of the concept of partial epilepsy.

The International League Against Epilepsy has devised classifications which subdivide both epileptic seizures and the epilepsies and epileptic syndromes into two main types: generalized and partial. Epileptogenesis in the partial variety is believed to originate in a localized part of the cerebral cortex and results in clinical manifestations which appear to commence in only a restricted part of the sufferer's body. Use of the term 'partial' in relation to these entities has often been said to date back to James Cowles Prichard (1786-1849) who was the author of the second major work on epilepsy to be written in the UK. While Prichard certainly described 'partial epilepsy', he stated that he intended the words to refer to the fact that the disorder he described under that designation was only partly, and not fully, epileptic in nature. He did not refer to the fact that it affected only part of the body as his basis for using the term. In the absence of knowledge of localization of function in the cerebral cortex at Prichard's time of writing, he had no basis for deducing that the underlying epileptic process arose in only part of the brain. However, there is an earlier mention of the use of the word 'partial' in relation to epilepsy. This is to be found in the writings of the great Scottish physician William Cullen (1710-1790), and there is reason to believe that Prichard should have been aware of this. Cullen used 'partial' with an intention similar to the modern one, employing the word to refer to seizures which affected only part of the body. Credit for the origin of the idea of a 'partial' epilepsy should belong to Cullen; not only did he have priority over Prichard but his concept was closer to the modern one than was Prichard's.

This qualitative study explored the challenges that Greek parents/caregivers of children with controlled epilepsy (CwE) face regarding the disorder. Interviews were conducted based on open-ended questions guided by a review of the literature. A total of 91 parents/caregivers were recruited by neurologists at the neurology clinics of two Athens public hospitals. A hermeneutic phenomenological approach was used to explore parent/caregiver experiences. The data were grouped and analyzed through a textual interpretation. Two key challenges were identified for parents of CwE: the disclosure of epilepsy and the absence of adequate information about coping with epilepsy. Parents in Greece were hesitant to reveal their child's epilepsy to school staff and their wider social milieu. Also, although satisfied with the patient-centered approach they experienced with their hospital doctor, parents/caregivers found that they needed more education about the existing sources of psychosocial and emotional support to cope with their child's epilepsy personally and as a family. Finally, the parents/caregivers who let their child know about the epilepsy and discussed the implications with the child found that parent-child communication improved. This study provides valuable insight into the impact of epilepsy on parents of CwE, which might help hospital and school staff support families with greater understanding, sensitivity, and skill. The findings suggest that Greek authorities should staff hospitals and schools with experts and more systematically advertise sources of information about epilepsy and ways to cope with it.

Investigate if quality of life (QOL) normalizes on long-term follow-up after surgery for partial epilepsy in children. This is a cohort study with controls in which a consecutive cohort of nineteen 2-14-year-old children who underwent focal resections for intractable partial seizures between 1996 and 2006, were matched with 19 non-surgery intractable partial epilepsy patients, and with 19 healthy subjects. The two epilepsy groups were matched for age, sex, socio-economic status (SES), cognitive level, seizure type, and seizure frequency. The healthy group was matched with the two epilepsy groups for age, sex, SES, and cognitive level. QOL was assessed using the QOLCE (Quality of Life in Childhood Epilepsy Questionnaire). In the surgery group (follow-up 3.84+/-2.26 years), 78.9% had Engel class-I versus 21.1% in non-surgery (p=0.01) (follow-up 3.44+/-2.95 years). Surgery patients were similar to healthy subjects in the social, emotional, cognitive, behavioral, and overall QOL (p>0.05) but had lower scores in the total QOL, physical, and health domains (p0.05, power>0.8). Our data indicate that epilepsy surgery for partial seizures in children is associated with better QOL as compared to children with intractable epilepsy who are not operated on, and suggest that in those who achieve seizure freedom normal QOL may at least potentially be possible.

In a previous study we demonstrated children with Benign Rolandic Epilepsy have normal intelligence and language ability. However, difficulties in verbal and visual memory and aspects of phonological awareness were found compared to normative data. To address the methodological limitations related to the use of normative data, we compared the same cohort of children with Benign Rolandic Epilepsy to a matched control group. Controls (n=40) matched on age and gender to the Benign Rolandic Epilepsy cohort underwent neuropsychological assessment. The life functioning of the control group was assessed using a modified version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The study confirmed the previous findings of memory and phonological awareness difficulties. In addition, the children with Benign Rolandic Epilepsy had significantly lower IQ scores than the matched control group. Paired sample t-tests showed that on 8 of 11 QOLCE scales, children with Benign Rolandic Epilepsy were rated by parents as having poorer life functioning compared to matched controls, including lower parental ratings on the subscales of memory and language. Benign Rolandic Epilepsy has an excellent seizure prognosis, but this study further emphasizes potential cognitive difficulties. Using an age and gender matched control group, the previous findings of memory and phonological awareness difficulties were validated. These problems in cognition were also identified by parents of children with Benign Rolandic Epilepsy as problematic and impacting upon the child's quality of life.

This study investigated the possible presence of sensory-motor developmental impairments in preschool children with epilepsy and explored epilepsy impact on their activities and quality of life and on the stress load of their family. Study participants were children aged 2-6years diagnosed with epilepsy without any other comorbidities (epi-only children). The instruments used for assessment included the Neurological, Sensory, Motor, Developmental Assessment (NSMDA) scale for sensory-motor development, the Impact of Childhood Neurologic Disability Scale (ICNDS), and the Impact of Pediatric Epilepsy Scale (IPES) for disease impact on disability and Quality of Life (QoL), as well as the Pediatric Outcomes Data Collection Instrument (PODCI) for functional health status, and the Parental Stress Scale (PSS) for the family stress load. Required data were obtained from direct testing or observation of children's activities and mother-supplied answers to questions. Eighty-two children were investigated. The NSMDA scores were in the normal development range 6-8. Significant moderate impact of the disease on disability and QoL was estimated with the ICNDS and IPES instruments. The PODCI scores were similar to healthy population levels except for the happiness dimension which was better for children with epilepsy. PSS were significantly above normal. The functional health and QoL of the children as well as their family stress were found to be positively correlated with increasing age. It is found that epilepsy does not degrade neuromotor development and functional health status of preschool epi-only children, though it has a significant impact on their neurological disability and QoL and the stress level of their families; this impact seems to decrease with age.

Mutations in the KIAA2022 gene have been reported in male patients with X-linked intellectual disability, and related female carriers were unaffected. Here, we report 14 female patients who carry a heterozygous de novo KIAA2022 mutation and share a phenotype characterised by intellectual disability and epilepsy. Reported females were selected for genetic testing because of substantial developmental problems and/or epilepsy. X-inactivation and expression studies were performed when possible. All mutations were predicted to result in a frameshift or premature stop. 12 out of 14 patients had intractable epilepsy with myoclonic and/or absence seizures, and generalised in 11. Thirteen patients had mild to severe intellectual disability. This female phenotype partially overlaps with the reported male phenotype which consists of more severe intellectual disability, microcephaly, growth retardation, facial dysmorphisms and, less frequently, epilepsy. One female patient showed completely skewed X-inactivation, complete absence of RNA expression in blood and a phenotype similar to male patients. In the six other tested patients, X-inactivation was random, confirmed by a non-significant twofold to threefold decrease of RNA expression in blood, consistent with the expected mosaicism between cells expressing mutant or normal KIAA2022 alleles. Heterozygous loss of KIAA2022 expression is a cause of intellectual disability in females. Compared with its hemizygous male counterpart, the heterozygous female disease has less severe intellectual disability, but is more often associated with a severe and intractable myoclonic epilepsy.

Epilepsy: Indian perspective

Full Text Available There are 50 million people living with epilepsy worldwide, and most of them reside in developing countries. About 10 million persons with epilepsy are there in India. Many people with active epilepsy do not receive appropriate treatment for their condition, leading to large treatment gap. The lack of knowledge of antiepileptic drugs, poverty, cultural beliefs, stigma, poor health infrastructure, and shortage of trained professionals contribute for the treatment gap. Infectious diseases play an important role in seizures and long-term burden causing both new-onset epilepsy and status epilepticus. Proper education and appropriate health care services can make tremendous change in a country like India. There have been many original researches in various aspects of epilepsy across India. Some of the geographically specific epilepsies occur only in certain regions of our country which have been highlighted by authors. Even the pre-surgical evaluation and epilepsy surgery in patients with drug-resistant epilepsy is available in many centers in our country. This article attempts to provide a complete preview of epilepsy in India.

The purpose of this study was to examine the following: 1) the course of perceived epilepsy-related stigma among children newly diagnosed with epilepsy (n=39) and their caregivers (n=97) over a two-year period, 2) the influence of seizure absence/presence on children and caregivers' perception of epilepsy-related stigma, and 3) the congruence of child and caregiver perception of child epilepsy-related stigma. Participants completed a measure of perceived epilepsy-related stigma at three time points, and seizure status was collected at the final time point. Results indicated that both caregivers (t(1,76)=-2.57, pstigma from diagnosis to two years postdiagnosis. No significant differences were found in caregiver and child reports of perceived stigma for children experiencing seizures compared with children who have been seizure-free for the past year. Results revealed poor caregiver-child agreement of perceived epilepsy-related stigma at all three time points. These data suggest that while children with epilepsy initially perceive epilepsy-related stigma at diagnosis, their perception of stigma decreases over time. Having a better understanding of the course of epilepsy-related stigma provides clinicians with information regarding critical times to support families with stigma reduction interventions.

The concept of symptomatic epilepsy and the complexities of assigning cause in epilepsy.

Science.gov (United States)

Shorvon, Simon

2014-03-01

The concept of symptomatic epilepsy and the difficulties in assigning cause in epilepsy are described. A historical review is given, emphasizing aspects of the history which are relevant today. The historical review is divided into three approximately semicentenial periods (1860-1910, 1910-1960, 1960-present). A definition of symptomatic epilepsy and this is followed by listing of causes of symptomatic epilepsy. The fact that not all the causes of idiopathic epilepsy are genetic is discussed. A category of provoked epilepsy is proposed. The complexities in assigning cause include the following: the multifactorial nature of epilepsy, the distinction between remote and proximate causes, the role of nongenetic factors in idiopathic epilepsy, the role of investigation in determining the range of causes, the fact that not all symptomatic epilepsy is acquired, the nosological position of provoked epilepsy and the view of epilepsy as a process, and the differentiation of new-onset and established epilepsy. The newly proposed ILAE classification of epilepsy and its changes in terminologies and the difficulties in the concept of acute symptomatic epilepsy are discussed, including the inconsistencies and gray areas and the distinction between idiopathic, symptomatic, and provoked epilepsies. Points to be considered in future work are listed. Copyright © 2013 Elsevier Inc. All rights reserved.

2016-10-01

The intention of our study was to identify predictive characteristics for long-term seizure control and running down phenomenon after surgical treatment of pharmacoresistant mesiotemporal lobe epilepsy (mTLE) with and without associated cortical dysplasia. Our study comprises a consecutive series of 458 patients who underwent surgical treatment for intractable mTLE at the Epilepsy Center Freiburg. Data evaluated included semiology, duration and frequency of seizures, results of presurgical diagnostics including video-EEG monitoring, MRI, PET and SPECT as well as postoperative seizure outcome. Results were evaluated forming two groups: Group A consisted of isolated mesiotemporal lesions. Group B comprised patients with mTLE and additional focal cortical dysplasia (FCD). Statistical evaluation was based on the Kaplan Meier survival analysis, using log-rank-tests and a multivariate regression model. Postoperative running down phenomenon was defined as seizure freedom after a period of gradual reduction of postoperative seizure frequency. This was compared to patients with ongoing epilepsy. Complete seizure freedom was achieved in 65.0% of investigated patients at 1year and in 56.5% at long-term follow-up of ≥5 years after surgery. Corresponding results were 64.2% and 56.8% at 1 and ≥5 years, respectively in group A and 66.4% and 56.0%, respectively in group B. Predictive for favorable postoperative outcome in the total group were younger age at surgery, shorter duration of epilepsy, absence of secondarily generalized tonic-clonic seizures (SGTCS), presence of strictly ipsilateral temporal interictal epileptiform discharges (IEDs), complete resection of the lesion as well as absence of postoperative epileptiform activity and of early postoperative seizures. In subgroup analyses, patients of group A demonstrated longer postoperative seizure-free intervals with adolescent age at surgery, short duration of epilepsy before surgery and absence of SGTCS, whereas in

The majority of patients with complex partial seizures of unilateral temporal lobe origin have interictal temporal hypometabolism on [18F]fluorodeoxyglucose positron emission tomography (FDG PET) studies. Often, this hypometabolism extends to ipsilateral extratemporal sites. The use of accurately quantified metabolic data has been limited by the absence of an equally reliable method of anatomical analysis of PET images. We developed a standardized method for visual placement of anatomically configured regions of interest on FDG PET studies, which is particularly adapted to the widespread, asymmetric, and often severe interictal metabolic alterations of temporal lobe epilepsy. This method was applied by a single investigator, who was blind to the identity of subjects, to 10 normal control and 25 interictal temporal lobe epilepsy studies. All subjects had normal brain anatomical volumes on structural neuroimaging studies. The results demonstrate ipsilateral thalamic and temporal lobe involvement in the interictal hypometabolism of unilateral temporal lobe epilepsy. Ipsilateral frontal, parietal, and basal ganglial metabolism is also reduced, although not as markedly as is temporal and thalamic metabolism

The aim of this study was to clarify characteristics of post-encephalopathic epilepsy (PEE) in children after acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), paying particular attention to precise diagnosis of seizure types. Among 262 children with acute encephalopathy/encephalitis registered in a database of the Tokai Pediatric Neurology Society between 2005 and 2012, 44 were diagnosed with AESD according to the clinical course and magnetic resonance imaging (MRI) findings and were included in this study. Medical records were reviewed to investigate clinical data, MRI findings, neurologic outcomes, and presence or absence of PEE. Seizure types of PEE were determined by both clinical observation by pediatric neurologists and ictal video-electroencephalography (EEG) recordings. Of the 44 patients after AESD, 10 (23%) had PEE. The period between the onset of encephalopathy and PEE ranged from 2 to 39 months (median 8.5 months). Cognitive impairment was more severe in patients with PEE than in those without. Biphasic seizures and status epilepticus during the acute phase of encephalopathy did not influence the risk of PEE. The most common seizure type of PEE on clinical observation was focal seizures (n = 5), followed by epileptic spasms (n = 4), myoclonic seizures (n = 3), and tonic seizures (n = 2). In six patients with PEE, seizures were induced by sudden unexpected sounds. Seizure types confirmed by ictal video-EEG recordings were epileptic spasms and focal seizures with frontal onset, and all focal seizures were startle seizures induced by sudden acoustic stimulation. Intractable daily seizures remain in six patients with PEE. We demonstrate seizure characteristics of PEE in children after AESD. Epileptic spasms and startle focal seizures are common seizure types. The specific seizure types may be determined by the pattern of diffuse subcortical white matter injury in AESD and age-dependent reorganization of the brain

Differentiating between occipital lobe epilepsy (OLE) and temporal lobe epilepsy (TLE) is often challenging. This retrospective case-control study compares OLE to TLE and explores markers that suggest the diagnosis of OLE. We queried the Jefferson Epilepsy Center surgery database for patients who underwent a resection that involved the occipital lobe. For each patient with OLE, three sequential case-control patients with TLE were matched. Demographic characteristics, symptoms, electrophysiological findings, imaging findings, and surgical outcome were compared. Nineteen patients with OLE and 57 patients with TLE were included in the study. Visual symptoms were unique to patients with OLE (8/19) and were not reported by patients with TLE (P Occipital interictal spikes (IIS) were found only in one-third of the patients with OLE (6/19) and in no patients with TLE (P lobe were found in five of 19 patients with OLE vs one of 57 patients with TLE (P = 0.003). IIS involved more than one lobe of the brain in most patients with OLE (11/19) but only in nine of 57 the TLE group.

To evaluate the phenotypic spectrum associated with mutations in TBC1D24. We acquired new clinical, EEG, and neuroimaging data of 11 previously unreported and 37 published patients. TBC1D24 mutations, identified through various sequencing methods, can be found online (http://lovd.nl/TBC1D24). Forty-eight patients were included (28 men, 20 women, average age 21 years) from 30 independent families. Eighteen patients (38%) had myoclonic epilepsies. The other patients carried diagnoses of focal (25%), multifocal (2%), generalized (4%), and unclassified epilepsy (6%), and early-onset epileptic encephalopathy (25%). Most patients had drug-resistant epilepsy. We detail EEG, neuroimaging, developmental, and cognitive features, treatment responsiveness, and physical examination. In silico evaluation revealed 7 different highly conserved motifs, with the most common pathogenic mutation located in the first. Neuronal outgrowth assays showed that some TBC1D24 mutations, associated with the most severe TBC1D24-associated disorders, are not necessarily the most disruptive to this gene function. TBC1D24-related epilepsy syndromes show marked phenotypic pleiotropy, with multisystem involvement and severity spectrum ranging from isolated deafness (not studied here), benign myoclonic epilepsy restricted to childhood with complete seizure control and normal intellect, to early-onset epileptic encephalopathy with severe developmental delay and early death. There is no distinct correlation with mutation type or location yet, but patterns are emerging. Given the phenotypic breadth observed, TBC1D24 mutation screening is indicated in a wide variety of epilepsies. A TBC1D24 consortium was formed to develop further research on this gene and its associated phenotypes. © 2016 American Academy of Neurology.

Epilepsy and driving

Directory of Open Access Journals (Sweden)

Full Text Available Epilepsy poses a risk for all participants in road traffic; therefore people with epilepsy do not meet the criteria for an unlimited driving license. Their driving is affected not only by epileptic seizures causing impaired consciousness and involuntary movements, but also by antiepileptic drugs with their many unwanted affects. The experts have not yet agreed on whether people with epilepsy have an increased risk of experiencing a road traffic accident. However, recent data suggests that the overall risk is lower compared to other medical conditions. Scientific evidence forms the basis of legislation, which by limiting people with epilepsy, enables all participants in road traffic to drive in the safest possible environment. The legislation that governs epilepsy and driving in Slovenia has been recently thoroughly reformed and thus allows a less discriminatory management of people with epilepsy. Although people with epilepsy experience many issues in their daily life, including their personal relationships and employment, they often list the need for driving as a top concern in surveys. General physicians play an important role in managing the issues of people with epilepsy.

Drug resistance in epilepsy is common despite many antiepileptic drugs (AEDs) available for treatment. The development of drug resistant epilepsy may be a result of multiple factors. Several previous studies reported that the major vault protein (MVP) was significantly increased in epileptogenic brain tissues resected from patients with partial-onset seizures, indicating the possible involvement of MVP in drug resistance. In this article, we aimed to identify the association between single nucleotide polymorphisms (SNPs) of MVP gene and drug resistance of partial epilepsy in a Chinese Han population. A total of 510 patients with partial-onset seizures and 206 healthy controls were recruited. Among the patients, 222 were drug resistant and 288 were responsive. The selection of tagging SNPs was based on the Hapmap database and Haploview software and the genotyping was conducted on the Sequenom MassARRAY iPLEX platform. For the selected loci rs12149746, rs9938630 and rs4788186 in the MVP gene, there was no significant difference in allele or genotype distribution between the drug resistant and responsive groups, or between all of the patients and healthy controls. Linkage disequilibrium between any two loci was detected but there was no significant difference in haplotype frequency between the drug resistant and responsive groups. Our results suggest that MVP genetic polymorphisms and haplotypes may not be associated with drug resistance of partial epilepsy in the Chinese Han population. Copyright © 2015 Elsevier B.V.

Little is known about subgroups of children with epilepsy who may experience less favorable outcomes over time. The objectives of this study were to document trajectories of health-related quality of life (HRQL) and to identify predictors of the trajectory group in children with new-onset epilepsy. Data were obtained from the Health Related Quality of Life in Children with Epilepsy Study, a prospective multisite study of children 4-12 years old with new-onset epilepsy followed for 24 months. Health-related quality of life was measured using the Quality of Life in Childhood Epilepsy questionnaire. Trajectories of HRQL were investigated using latent class trajectory modeling. Multinomial logistic regression was used to identify child, parent, and family predictors of HRQL trajectories. A total of 374 families responded at baseline and 283 (76%) completed the study. Five HRQL trajectories were observed: low-increasing (4%), moderate-decreasing (12%), moderate-increasing (22%), high-increasing (32%), and high-stable (30%). Many children in the low-increasing, moderate-increasing, high-increasing, and high-stable had clinically meaningful improvements in HRQL: 82%, 47%, 63%, and 44%, respectively. In contrast, the majority of children in the moderate-decreasing group (56%) experienced clinically meaningful declines in their HRQL. Factors predicting trajectories were number of antiepileptic drugs prescribed, presence of comorbid behavior or cognitive problems, parent depression, and family functioning and demands. Results suggested that children with epilepsy are not homogenous but rather consist of groups with different trajectories and unique predictors of HRQL. Problems associated with child behavior and cognition were the strongest predictors identified. Given that several risk factors are modifiable, it is important to examine these as potential targets within a family-centered framework to improve HRQL of children with new-onset epilepsy.

The objective of the study was to compare the psychiatric and behavioral side effect (PBSE) profiles of both older and newer antiepileptic drugs (AEDs) in children and adolescent patients with epilepsy. We used logistic regression analysis to test the correlation between 83 non-AED/patient related potential predictor variables and the rate of PBSE. We then compared for each AED the rate of PBSEs and the rate of PBSEs that led to intolerability (IPBSE) while controlling for non-AED predictors of PBSEs. 922 patients (≤18 years old) were included in our study. PBSEs and IPBSEs occurred in 13.8% and 11.2% of patients, respectively. Overall, a history of psychiatric condition, absence seizures, intractable epilepsy, and frontal lobe epilepsy were significantly associated with increased PBSE rates. Levetiracetam (LEV) had the greatest PBSE rate (16.2%). This was significantly higher compared to other AEDs. LEV was also significantly associated with a high rate of IPBSEs (13.4%) and dose-decrease rates due to IPBSE (6.7%). Zonisamide (ZNS) was associated with significantly higher cessation rate due to IPBSE (9.1%) compared to other AEDs. Patients with a history of psychiatric condition, absence seizures, intractable epilepsy, or frontal lobe epilepsy are more likely to develop PBSE. PBSEs appear to occur more frequently in adolescent and children patients taking LEV compared to other AEDs. LEV-attributed PBSEs are more likely to be associated with intolerability and subsequent decrease in dose. The rate of ZNS-attributed IPBSEs is more likely to be associated with complete cessation of AED. Copyright © 2017 European Paediatric Neurology Society. Published by Elsevier Ltd.

This systematic review examines the effectiveness of Mozart's music in decreasing seizures in children with epilepsy (Mozart Effect) using the Johns Hopkins Nursing Evidence-Based Practice rating scale © . A search for articles with "Mozart Effect," "child*," and "epilepsy" was conducted in CINAHL Complete, Science Direct, Cochrane, and PubMed databases. Eight studies were selected based on the exclusion and inclusion criteria after removal of duplicates ( n = 17) and others ( n = 46). Studies included were English language, peer reviewed, published between April 2010 and February 2017, and available in full text with an abstract. Quasi-experimental studies demonstrate that the Mozart Effect May reduce epileptiform discharges or seizures in children and has potential as an adjunct to medical management of seizure activity or alone when medication or surgery is not accepted. A causal relationship between the music of Mozart and decreased seizure activity has yet to be demonstrated.

The diagnosis of epilepsy should be made as early as possible to give a child the best chance for treatment success and also to decrease complications such as learning difficulties and social and behavioral problems. In this study, we aimed to assess the ability of magnetic resonance spectroscopy (MRS) in detecting the lateralization side in patients with Temporal lobe epilepsy (TLE) in correlation with EEG and MRI findings. This was a case-control study including 40 patients diagnosed (clinically and by EEG) as having temporal lobe epilepsy aged 8 to 14 years (mean, 10.4 years) and 20 healthy children with comparable age and gender as the control group. All patients were subjected to clinical examination, interictal electroencephalography and magnetic resonance imaging (MRI). Proton magnetic resonance spectroscopic examination (MRS) was performed to the patients and the controls. According to the findings of electroencephalography, our patients were classified to three groups: Group 1 included 20 patients with unitemporal (lateralized) epileptic focus, group 2 included 12 patients with bitemporal (non-lateralized) epileptic focus and group 3 included 8 patients with normal electroencephalography. Magnetic resonance spectroscopy could lateralize the epileptic focus in 19 patients in group 1, nine patients in group2 and five patients in group 3 with overall lateralization of (82.5%), while electroencephalography was able to lateralize the focus in (50%) of patients and magnetic resonance imaging detected lateralization of mesial temporal sclerosis in (57.5%) of patients. Magnetic resonance spectroscopy is a promising tool in evaluating patients with epilepsy and offers increased sensitivity to detect temporal pathology that is not obvious on structural MRI imaging.

Television as an external stimulation can precipitate epileptic seizures. Today this kind of epilepsy is known as television epilepsy. As children spend much of their time watching television, it is important to study this type of epilepsy in this age group. This study was designed to describe the clinical and some demographic characteristics of television epilepsy in Iranian children. Patients who were diagnosed as having television epilepsy with an age less than 12 years were recruited from outpatient neurology clinics in Isfahan, Iran, from September 2002 through September 2006. We collected the case-related information including electroencephalograms, radiologic findings, and patients' history. Thirty patients with television epilepsy with the age less than 12 years were identified. Of whom 17 (56.7%) were females and 13 (43.3%) were males. The mean age at the onset of seizure was 9.9+/-2.1 years. Children had absence (3.3%), myoclonic (3.3%), and generalized tonic-clonic (93.3+/-) seizures in response to intermittent photic stimulations. Interictal epileptiform discharges in electroencephalograms were detected in 83.3%. In addition, neuroimaging findings were normal in 96.7% of the patients. In our study, 56.7% of the children had pure television epilepsy and 43.3% experienced other types of generalized seizure. During the follow-up period after initiation of variable drug treatments including valproic acid, carbamazepine, phenobarbital, clonazepam, ethosuximide, and lamotrigine all the patients had complete seizure remission. The clinical and demographic differences of our patients compared with other reports are probably due to genetic differences. In our study, it was demonstrated that carbamazepine could be used in children with television epilepsy because it had successfully terminated seizures in 43.3% of the patients.

Purpose To examine whether family history of unprovoked seizures is associated with behavioral disorders in epilepsy probands, thereby supporting the hypothesis of shared underlying genetic susceptibility to these disorders. Methods We conducted an analysis of the 308 probands with childhood onset epilepsy from the Connecticut Study of Epilepsy with information on first degree family history of unprovoked seizures and of febrile seizures whose parents completed the Child Behavior Checklist (CBCL) at the 9-year follow-up. Clinical cut-offs for CBCL problem and DSM-Oriented scales were examined. The association between first degree family history of unprovoked seizure and behavioral disorders was assessed separately in uncomplicated and complicated epilepsy and separately for first degree family history of febrile seizures. A subanalysis, accounting for the tendency for behavioral disorders to run in families, adjusted for siblings with the same disorder as the proband. Prevalence ratios were used to describe the associations. Key findings In probands with uncomplicated epilepsy, first degree family history of unprovoked seizure was significantly associated with clinical cut-offs for Total Problems and Internalizing Disorders. Among Internalizing Disorders, clinical cut-offs for Withdrawn/Depressed, and DSM-Oriented scales for Affective Disorder and Anxiety Disorder were significantly associated with family history of unprovoked seizures. Clinical cut-offs for Aggressive Behavior and Delinquent Behavior, and DSM-Oriented scales for Conduct Disorder and Oppositional Defiant Disorder were significantly associated with family history of unprovoked seizure. Adjustment for siblings with the same disorder revealed significant associations for the relationship between first degree family history of unprovoked seizure and Total Problems and Agressive Behavior in probands with uncomplicated epilepsy; marginally significant results were seen for Internalizing Disorder

Diagnosis of epilepsy is known to impact health-related quality of life (HRQOL) of children with new-onset epilepsy and can also influence their conceptualization and valuation of HRQOL construct, also known as response shift. This study investigates the presence of response shift in a cohort of children with new-onset epilepsy. Data are from the HEalth-Related QUality of Life in children with Epilepsy Study, a prospective cohort study of 373 children with new-onset epilepsy. Hypotheses about the presence of reconceptualization, reprioritization, and recalibration response shift were tested in the Quality of Life in Childhood Epilepsy (QOLCE-55) Questionnaire, a parent-reported, disease-specific HRQOL measure, using Oort's structural equation model between baseline and 1-year follow-up. Model fit was assessed using log-likelihood ratio test, root mean square error of approximation, and comparative fit index. Small positive uniform recalibration response shift effects were observed on physical, emotional, and social functioning domains of the QOLCE-55, but negligibly small negative nonuniform recalibration response shift effect was observed on social functioning domain. There was no significant change in overall QOLCE-55 scores over time after adjusting for response shift effects. Parents of children with new-onset epilepsy are likely to positively recalibrate (upward bias) their assessments of their children's HRQOL over a 1-year period after diagnosis. This study highlights the potential benefits of response shift as a desired consequence in parents' perception of changes in HRQOL of children with new-onset epilepsy. Copyright © 2017 Elsevier Inc.

Potegal, Michael; Drewel, Elena H; MacDonald, John T

2018-01-01

We explored associations between EEG pathophysiology and emotional/behavioral (E/B) problems of children with two types of epilepsy using standard parent questionnaires and two new indicators: tantrums recorded by parents at home and brief, emotion-eliciting situations in the laboratory. Children with Benign Rolandic epilepsy (BRE, N = 6) reportedly had shorter, more angry tantrums from which they recovered quickly. Children with Complex Partial Seizures (CPS, N = 13) had longer, sadder tantrums often followed by bad moods. More generally, BRE correlated with anger and aggression; CPS with sadness and withdrawal. Scores of a composite group of siblings ( N = 11) were generally intermediate between the BRE and CPS groups. Across all children, high voltage theta and/or interictal epileptiform discharges (IEDs) correlated with negative emotional reactions. Such EEG abnormalities in left hemisphere correlated with greater social fear, right hemisphere EEG abnormalities with greater anger. Right hemisphere localization in CPS was also associated with parent-reported problems at home. If epilepsy alters neural circuitry thereby increasing negative emotions, additional assessment of anti-epileptic drug treatment of epilepsy-related E/B problems would be warranted.

Neurocognitive impairment represents one of the most common comorbidities occurring in children with idiopathic epilepsy. Diagnosis of the idiopathic form of epilepsy requires the absence of any macrostructural abnormality in the conventional MRI. Though changes can be seen at the microstructural level imaged using advanced techniques such as the Diffusion Tensor Imaging (DTI). The aim of this work is to study the correlation between the microstructural white matter DTI findings, the electroencephalographic changes and the cognitive dysfunction in children with active idiopathic epilepsy. A comparative cross-sectional study, included 60 children with epilepsy based on the Stanford-Binet 5th Edition Scores was conducted. Patients were equally assigned to normal cognitive function or cognitive dysfunction groups. The history of the epileptic condition was gathered via personal interviews. All patients underwent brain Electroencephalography (EEG) and DTI, which was analyzed using FSL. The Fractional Anisotropy (FA) was significantly higher whereas the Mean Diffusivity (MD) was significantly lower in the normal cognitive function group than in the cognitive dysfunction group. This altered microstructure was related to the degree of the cognitive performance of the studied children with epilepsy. The microstructural alterations of the neural fibers in children with epilepsy and cognitive dysfunction were significantly related to the younger age of onset of epilepsy, the poor control of the clinical seizures, and the use of multiple antiepileptic medications. Children with epilepsy and normal cognitive functions differ in white matter integrity, measured using DTI, compared with children with cognitive dysfunction. These changes have important cognitive consequences. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available Objective. To evaluate the perceived social stigma of people with epilepsy with regard to the question of employability. Methods. A structured questionnaire was given to two groups of people with chronic diseases: those with epilepsy (study group and those with heart disease (control group. The questions concerned employability. Results. Having epilepsy was more strongly associated with higher unemployment rates (p<0.0001; job layoffs (p=0.001; being unfit to work (p<0.0001; feeling shame for having the disease (p=0.014; absence of partners (p=0.026; and depression (p=0.004. The tendency to hide their disease from their employers was similar for the two groups. Conclusion. The age discrepancy between groups was an important limiting factor of this study. However, despite the limited number of participants and the age difference between the groups, there is no impediment in stating that people with epilepsy show high rates of unemployment, depression, and stigma.

2016-07-01

The objective of this study was to compare the seizure characteristics and treatment outcomes in patient groups with temporal lobe epilepsy (TLE) identified with isolated amygdala enlargement (AE) on magnetic resonance imaging studies. PubMed, Embase, and the Cochrane Library were searched for relevant studies using the keywords 'amygdala enlargement', 'epilepsy', and 'seizures' in April 2015. Human studies, written in English, that investigated cohorts of patients with TLE and AE were included. Of 204 abstracts initially identified using the search strategy, 14 studies met the inclusion criteria (11 epilepsy studies and 3 psychiatry studies). Ultimately, 8 full studies on AE and TLE involving 107 unique patients were analyzed. Gender distribution consisted of 50 males and 57 females. Right amygdala enlargement was seen in 39 patients, left enlargement in 58 patients, and bilateral enlargement in 7 patients. Surgical resection was performed in 28 patients, with the most common finding being dysplasia/hamartoma or focal cortical dysplasia. Most studies involved small samples of less than 12 patients. There was a wide discrepancy in the methods used to measure amygdala volume, in both patients and controls, hindering comparisons. Most TLE with AE studies observed a later age of seizure onset (mean: 32.2years) compared with studies involving TLE with HS (mean of mid- to late childhood). A higher frequency of complex partial seizures compared with that of convulsive seizures is seen in patients with AE (67-100% vs. 26-47%), and they have an excellent response to antiepileptic drugs (81.8%-100% of seizure-free patients). All studies that included controls also found a significant difference in frequency of seizure types between their cases and controls. Reliable assessment of amygdala volume remains a critical issue hindering better understanding of the clinical management and research of this focal epilepsy syndrome. Within these limitations, the literature suggests

Pharmacogenomics in epilepsy.

There is high variability in the response to antiepileptic treatment across people with epilepsy. Genetic factors significantly contribute to such variability. Recent advances in the genetics and neurobiology of the epilepsies are establishing the basis for a new era in the treatment of epilepsy, focused on each individual and their specific epilepsy. Variation in response to antiepileptic drug treatment may arise from genetic variation in a range of gene categories, including genes affecting drug pharmacokinetics, and drug pharmacodynamics, but also genes held to actually cause the epilepsy itself. From a purely pharmacogenetic perspective, there are few robust genetic findings with established evidence in epilepsy. Many findings are still controversial with anecdotal or less secure evidence and need further validation, e.g. variation in genes for transporter systems and antiepileptic drug targets. The increasing use of genetic sequencing and the results of large-scale collaborative projects may soon expand the established evidence. Precision medicine treatments represent a growing area of interest, focussing on reversing or circumventing the pathophysiological effects of specific gene mutations. This could lead to a dramatic improvement of the effectiveness and safety of epilepsy treatments, by targeting the biological mechanisms responsible for epilepsy in each specific individual. Whilst much has been written about epilepsy pharmacogenetics, there does now seem to be building momentum that promises to deliver results of use in clinic. Copyright © 2017 The Authors.

Stigma of epilepsy.

Science.gov (United States)

Bandstra, Nancy F; Camfield, Carol S; Camfield, Peter R

2008-09-01

Epilepsy directly affects 50 million people worldwide. Most can achieve excellent seizure control; however, people living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions and misunderstandings that have persisted for thousands of years. This paper reviews the frequency and nature of stigma toward epilepsy. Significant negative attitudes prevail in the adolescent and adult public worldwide leading to loneliness and social avoidance both in school and in the workplace. People with epilepsy are often wrongly viewed as having mental health and antisocial issues and as being potentially violent toward others. Twenty-five percent of adults having epilepsy describe social stigma as a result of their epilepsy. They fear rejection and often feel shame or loneliness from this diagnosis. The psychosocial and social impact of epilepsy is significant. Yet few specific interventions have been demonstrated to alter this perception. The effect on public education is primarily short-term, while change over the long-term in attitudes and inaccurate beliefs have not presently been proven effective. School education programming demonstrates improved knowledge and attitude a month after a classroom intervention, but persisting change over a longer period of time has not been evaluated. In-depth adult psycho-educational programs for adults with epilepsy improves knowledge, coping skills and level of felt stigma. However these gains have not demonstrated persistence over time. Myths, misconceptions and misunderstandings about epilepsy continue and programs aimed at increasing knowledge and reducing negative public attitudes should be enhanced.

Epilepsy, a complex spectrum of disorders, affects about 2.9 million people in the U.S. Similar to other chronic disorders, people with epilepsy face challenges related to management of the disorder, its treatment, co-occurring depression, disability, social disadvantages, and stigma. Two national conferences on public health and epilepsy (1997, 2003) and a 2012 IOM report on the public health dimensions of epilepsy highlighted important knowledge gaps and emphasized the need for evidence-based, scalable epilepsy self-management programs. The Centers for Disease Control and Prevention translated recommendations on self-management research and dissemination into an applied research program through the Prevention Research Centers Managing Epilepsy Well (MEW) Network. MEW Network objectives are to advance epilepsy self-management research by developing effective interventions that can be broadly disseminated for use in people's homes, healthcare providers' offices, or in community settings. The aim of this report is to provide an update on the MEW Network research pipeline, which spans efficacy, effectiveness, and dissemination. Many of the interventions use e-health strategies to eliminate barriers to care (e.g., lack of transportation, functional limitations, and stigma). Strengths of this mature research network are the culture of collaboration, community-based partnerships, e-health methods, and its portfolio of prevention activities, which range from efficacy studies engaging hard-to-reach groups, to initiatives focused on provider training and knowledge translation. The MEW Network works with organizations across the country to expand its capacity, help leverage funding and other resources, and enhance the development, dissemination, and sustainability of MEW Network programs and tools. Guided by national initiatives targeting chronic disease or epilepsy burden since 2007, the MEW Network has been responsible for more than 43 scientific journal articles, two

Population-based studies have demonstrated that the increased mortality is often related to the cause of the epilepsy. Common etiologies include neoplasia, cerebrovascular disease, and pneumonia. Deaths in selected cohorts, such as sudden unexpected death in epilepsy (SUDEP), status epilepticus (SE), suicides, and accidents are more frequently epilepsy-related. SUDEP is a particular cause for concern in younger people, and whether and when SUDEP should be discussed with patients with epilepsy remain problematic issues. Risk factors for SUDEP include generalized tonic-clonic seizures, increased seizure frequency, concomitant learning disability, and antiepileptic drug polypharmacy. The overall incidence of SE may be increasing, although case fatality rates remain constant. Mortality is frequently secondary to acute symptomatic disorders. Poor compliance with treatment in patients with epilepsy accounts for a small proportion of deaths from SE. The incidence of suicide is increased, particularly for individuals with epilepsy and comorbid psychiatric conditions. Late mortality figures in patients undergoing epilepsy surgery vary and are likely to reflect differences in case selection. Future studies of mortality should be prospective and follow agreed guidelines to better quantify risk and causation in individual populations.

Health-related quality of life (HRQL) is compromised in children with epilepsy. The current study aimed to identify correlates of HRQL in children with drug resistant epilepsy. Data came from 115 children enrolled in the Impact of Pediatric Epilepsy Surgery on Health-Related Quality of Life Study (PEPSQOL), a multicenter prospective cohort study. Individual, clinical, and family factors were evaluated. HRQL was measured using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE), a parent-rated epilepsy-specific instrument, with composite scores ranging from 0 to 100. A series of univariable linear regression analyses were conducted to identify significant associations with HRQL, followed by a multivariable regression analysis. Children had a mean age of 11.85 ± 3.81 years and 65 (56.5%) were male. The mean composite QOLCE score was 60.18 ± 16.69. Child age, sex, age at seizure onset, duration of epilepsy, caregiver age, caregiver education, and income were not significantly associated with HRQL. Univariable regression analyses revealed that a higher number of anti-seizure medications (p = 0.020), lower IQ (p = 0.002), greater seizure frequency (p = 0.048), caregiver unemployment (p = 0.010), higher caregiver depressive and anxiety symptoms (p < 0.001 for both), poorer family adaptation, fewer family resources, and a greater number of family demands (p < 0.001 for all) were associated with lower HRQL. Multivariable regression analysis showed that lower child IQ (β = 0.20, p = 0.004), fewer family resources (β = 0.43, p = 0.012), and caregiver unemployment (β = 6.53, p = 0.018) were associated with diminished HRQL in children. The results emphasize the importance of child cognition and family variables in the HRQL of children with drug-resistant epilepsy. The findings speak to the importance of offering comprehensive care to children and their families to address the nonmedical features that impact on HRQL. Wiley Periodicals, Inc. © 2016

Full Text Available Introduction: Epilepsy is a common disorder worldwide, commonly starting during childhood. Despite the high impact of psychiatric comorbidities in these patients, little is known about Iranian children with epilepsy. Methods: This cross sectional study was carried out in the tertiary clinics of the Tabriz University of Medical Sciences, Tabriz, Iran. All of the children (aged between 6 and 18 with a diagnosis of epilepsy were enrolled in this study. A semi-structured psychiatric interview was carried out using the Farsi (Persian version of the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL. Results: From a total of 298 participants, 270 (90.6% completed the process, including 120 (44.4% girls and 150 (55.6% boys. At least one psychiatric diagnosis was made in 222 (82.2% patients. The most prevalent psychiatric disorders in children and adolescents with epilepsy were attention deficit/hyperactivity disorder (34.4%, major depressive disorder (MDD (29.6%, social phobia (14.8% and oppositional defiant disorder (ODD (14.8%. Agoraphobia and anorexia nervosa were significantly more prevalent among girls. The following disorders were more prevalent in children aged between 13 and 18: MDD (47.5%, psychotic disorder (2.5%, social phobia (23.7%, generalized anxiety disorder (GAD (15.3%, conduct disorder (13.6%, chronic motor tic disorder (13.6% and substance related disorders (4.8%. Separation anxiety (15.1% and enuresis (1.5%, on the other hand, were more prevalent among younger children. A logistic regression model showed that psychiatric disorders in parents or siblings could independently predict at least one psychiatric comorbidity in children with epilepsy.Conclusion: Iranian children with epilepsy face a high burden of psychiatric and behavioral comorbidities compared to same aged general population that should be considered for comprehensive care.

The ketogenic diet is an effective therapy for childhood epilepsy, but its important impacts on families could affect successful treatment. We assessed medical and psychosocial factors associated with successful ketogenic diet treatment. A total of 23 families of patients treated with ketogenic diet completed questionnaires (30% response), including inquiries about challenges to successful dietary treatments and validated family functioning scales. Of these, 14 were considered successful (diet discontinued once the child was seizure-free or continued as clinically indicated). Family-identified challenges were food preparation time (n = 11) and that the diet was too restrictive (n = 9). Neither Medicaid insurance nor family functioning scale scores were significantly associated with successful treatment. Lower seizure frequency prior to ketogenic diet initiation (P = .02) and postdiet seizure improvement (P = .01) were associated with increased odds of success. Effective ketogenic diet treatment is dictated both by psychosocial and epilepsy-related influences. A focus on understanding the psychosocial issues may help to improve families' experiences and success with the ketogenic diet.

Epilepsy has long been associated with cognitive dysfunction and educational underachievement. The purpose of the study was to describe the baseline findings from a larger prospective study. New cases of epilepsy aged 6-16 years seen at a paediatric neurology clinic in Ibadan, Nigeria were evaluated for any evidence of cognitive impairment. Intelligence quotient (IQ) of the participants was measured using the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Scores on cognitive subtests and Full Scale IQ (FSIQ) were computed and association between the subsets scores and seizure variables were calculated. 40 children, 24 males and 16 females were studied and their ages ranged from 6 to 16 years with a mean of 10.8 (SD=3.0) years. Global intellectual functioning as measured by the WISC-IV was in the normal range (FSIQ scores intellectual disability. The strongest correlation was between 'caregiver's assessment of school performance' and FSIQ, (r = 0.70; p< 0.001). Age at onset of epilepsy and seizure type had no significant association with scores on the WISC-IV composite scores. There is a high prevalence of significant cognitive dysfunction in Nigerian children with epilepsy, even in the absence of any known brain insult. All children with epilepsy should have routine IQ assessment following diagnosis, in order to allow for early intervention when indicated, and thus, improved outcomes.

Epilepsy and seizures are reported among the neurological manifestations of antiphospholipid syndrome (APS) at a prevalence rate of approximately 8%, which is nearly 10 times the prevalence of epilepsy in the general population. The association of seizures with antiphospholipid antibodies (aPL) is even more significant in the presence of systemic lupus erythematosus (SLE). In this review, we discuss the epidemiological, pathophysiological, laboratory, clinical, and radiological aspects of this association, and derive suggestions on when to consider testing for aPL in epileptic patients and how to manage seizures secondary to APS based on literature data. Epilepsy due to APS should be considered in young patients presenting with seizures of unknown origin. Temporal lobe epilepsy seems to be particularly prevalent in APS patients. The pathogenesis is complex and may not only involve micro-thrombosis, but also a possible immune-mediated neuronal damage. Patients with seizures and positive aPL tend to develop thrombocytopenia and livedo racemosa more frequently compared with those without aPL. Magnetic resonance imaging (MRI) remains the imaging modality of choice in these patients. The presence of SLE and the presence of neurological symptoms significantly correlate with the presence of white matter changes on MRI. In contrast, the correlation between aPL positivity and the presence of white matter changes is very weak. Furthermore, MRI can be normal in more than 30-40% of neuropsychiatric lupus patients with or without aPL. aPL testing is recommended in young patients presenting with atypical seizures and multiple hyper-intensity lesions on brain MRI in the absence of other possible conditions. New MRI techniques can better understand the pathology of brain damage in neuro-APS. The therapeutic management of epileptic APS patients relies on anti-epileptic treatment and anticoagulant agents when there is evidence of a thrombotic event. In the absence of consensual

Epilepsy: Is there hope?

Full Text Available Epilepsy is a highly prevalent chronic neurologic disorder and leads to social, behavioural, health and economic consequences. 'Treatment gap' varies from 10 per cent in developed countries to 75 per cent in low-income countries. Stigma and discrimination related to epilepsy are prevalent worldwide. Electroencephalography (EEG is considered the most important tool for evaluating the patient with epilepsy. Video-EEG monitoring is an important tool for confirming the seizure type and estimating the epileptogenic zone in the brain. Neuroimaging evaluation is important to determine the aetiology of the epilepsies. Genetic testing has increased the probability of identifying the causes of some types of epilepsies. Epilepsy can be treated in an affordable way with low-cost medications. Refractory epilepsies occur in approximately one-third of recently diagnosed patients with epilepsy. For this group of patients, there are options of surgical treatment, diets and neurostimulation to improve seizure control and quality of life. In poorly organized societies, there is a lack of prioritization of epilepsy in national health policies, limited resources for trained personnel and a shortage of basic antiepileptic medications. There is evidence of improvement in the understanding of epilepsy and a clear progress in the management of epileptic seizures in recent times.

Purpose Epilepsy is common in sub-Saharan Africa (SSA), but the clinical features and consequences are poorly characterized. Most studies are hospital-based, and few studies have compared different ecological sites in SSA. We described active convulsive epilepsy (ACE) identified in cross-sectional community-based surveys in SSA, to understand the proximate causes, features, and consequences. Methods We performed a detailed clinical and neurophysiologic description of ACE cases identified from a community survey of 584,586 people using medical history, neurologic examination, and electroencephalography (EEG) data from five sites in Africa: South Africa; Tanzania; Uganda; Kenya; and Ghana. The cases were examined by clinicians to discover risk factors, clinical features, and consequences of epilepsy. We used logistic regression to determine the epilepsy factors associated with medical comorbidities. Key Findings Half (51%) of the 2,170 people with ACE were children and 69% of seizures began in childhood. Focal features (EEG, seizure types, and neurologic deficits) were present in 58% of ACE cases, and these varied significantly with site. Status epilepticus occurred in 25% of people with ACE. Only 36% received antiepileptic drugs (phenobarbital was the most common drug [95%]), and the proportion varied significantly with the site. Proximate causes of ACE were adverse perinatal events (11%) for onset of seizures before 18 years; and acute encephalopathy (10%) and head injury prior to seizure onset (3%). Important comorbidities were malnutrition (15%), cognitive impairment (23%), and neurologic deficits (15%). The consequences of ACE were burns (16%), head injuries (postseizure) (1%), lack of education (43%), and being unmarried (67%) or unemployed (57%) in adults, all significantly more common than in those without epilepsy. Significance There were significant differences in the comorbidities across sites. Focal features are common in ACE, suggesting identifiable and

Tantrums, Emotion Reactions and Their EEG Correlates in Childhood Benign Rolandic Epilepsy vs. Complex Partial Seizures: Exploratory Observations

Full Text Available We explored associations between EEG pathophysiology and emotional/behavioral (E/B problems of children with two types of epilepsy using standard parent questionnaires and two new indicators: tantrums recorded by parents at home and brief, emotion-eliciting situations in the laboratory. Children with Benign Rolandic epilepsy (BRE, N = 6 reportedly had shorter, more angry tantrums from which they recovered quickly. Children with Complex Partial Seizures (CPS, N = 13 had longer, sadder tantrums often followed by bad moods. More generally, BRE correlated with anger and aggression; CPS with sadness and withdrawal. Scores of a composite group of siblings (N = 11 were generally intermediate between the BRE and CPS groups. Across all children, high voltage theta and/or interictal epileptiform discharges (IEDs correlated with negative emotional reactions. Such EEG abnormalities in left hemisphere correlated with greater social fear, right hemisphere EEG abnormalities with greater anger. Right hemisphere localization in CPS was also associated with parent-reported problems at home. If epilepsy alters neural circuitry thereby increasing negative emotions, additional assessment of anti-epileptic drug treatment of epilepsy-related E/B problems would be warranted.

Sleep has been shown to be important to memory. Both sleep and memory have been found to be abnormal in patients with epilepsy. In this study, we explored the effects that nocturnal epileptiform discharges and the presence of a hippocampal lesion have on sleep patterns and memory. Twenty-five patients with focal epilepsy who underwent a 24-hr ambulatory EEG also completed the Everyday Memory Questionnaire (EMQ). The EEG record was scored for length of time spent in the various sleep stages, time spent awake after sleep onset, and rapid eye movement (REM) latency. Of these sleep variables, only REM latency differed when the epilepsy patients were divided on the bases of either presence/absence of nocturnal discharges or presence/absence of a hippocampal lesion. In both cases, presence of the abnormality was associated with longer latency. Furthermore, longer REM latency was found to be a better predictor of EMQ score than either number of discharges or presence of a hippocampal lesion. Longer REM latency was associated with a smaller percentage of time spent in slow-wave sleep in the early part of the night and may serve as a particularly sensitive marker to disturbances in sleep architecture.

Research has previously found a number of apparently contradictory patterns in the relationship between 'father absence' (having a non-resident father during childhood) and the expression of gender roles, as well as other sexually dimorphic traits such as aggression. In the current study we measured a battery of sexually differentiated traits in relation to family background. 133 men and 558 women from the United States and Australia completed the Bem Sex Role Inventory, the Barrett Impulsivity Scale, the Fear Survey Schedule and the Buss & Perry Aggression Questionnaire. Principal components analysis found two main axes of variation in these traits. Firstly, a general 'reactivity' factor, on which aggression, impulsivity, and fear all loaded positively, was weakly associated with father absence in women. Secondly, 'masculinity' (consisting of high scores on masculine traits, low fear, and physical and verbal aggression) was not associated with father absence. Participants (except American males) reporting a poor childhood relationship with their parents also had high 'reactivity' but not higher 'masculinity'. We found some evidence of a link between father absence and earlier age of first coitus in American females (although not in Australia), but there was no link with age of menarche in either country. Overall, the current results suggest that previous findings linking gender development with father absence in girls may have arisen from a tendency towards greater externalising and reactive behaviour rather than a change in gender development per se.

The objective of the following study is to assess parent reported quality of life (QOL) in children with epilepsy and to assess the demographic and clinical factors, which influence the QOL in children with epilepsy. We consecutively enrolled 40 children aged from 2 years to 14 years with active epilepsy who had undergone a comprehensive evaluation for epilepsy. Parents were enquired on baseline demographic variables including age, gender, socio-economic status and parental education. Clinical details of epilepsy including the type of epilepsy, seizure frequency were assessed. QOL was evaluated with the parent reported quality of life in childhood epilepsy (QOLCE) questionnaire. A total of 40 children were enrolled of which 55% (22/40) were males and the mean (standard deviation [SD]) age of enrolled children was 10.6 (2.7) years. The majority came from a rural background (80% [32/40]), were from lower (15 [37.5%]) or middle (23 [57.5%]) socio-economic status, with almost half (22 [55%]) of mothers being educated until high school. The overall mean (SD) QOL score was 66.7 (4.83). Lowest mean (SD) scores were observed in self-esteem (45.2 [7.3]) subscale and subscales with higher QOL scores included control/helplessness (82.1 [8.51]), anxiety (81.6 [12.55]) and social stigma (95.0 [11.6]). Parental education, socio-economic status (P = 0.96), frequency of seizure (P = 0.34) or type of epilepsy (P = 0.92) did not significantly affect the overall QOL among children with epilepsy. Our study concluded that overall QOL was compromised in Indian children with epilepsy. Demographic factors like parental education, socio-economic status and clinical factors like frequency of seizure or type of seizure did not significantly affect the QOL of epileptic children.

Imaging of epilepsy patients is challenging, since epileptogenic lesions (defined as structural lesions causally related to the epilepsy syndrome) may be small and often do not change during life. Prior clinical information about the epilepsy syndrome and the semiology of the seizures is needed in order to plan the examination properly. The effort to detect an epileptogenic lesion is directed to partial (focal) epilepsy syndromes whereas - by definition - no lesion is identified in idiopathic epilepsies. Most patients with partial epilepsies suffer from mesial temporal lobe epilepsies. In these patients, 2- to 3-mm-thick T2-weighted and fluid-attenuated inversion-recovery (FLAIR) fast spin echo slices along or perpendicular to the temporal lobe length axis have the highest diagnostic efficacy. In contrast, in patients with extratemporal lobe epilepsies perpendicular FLAIR slices through the anatomic region, from which, due to clinical and EEG criteria, the seizures are likely to originate, are preferred. The imaging features of common epileptogenic lesions (hippocampal sclerosis, long-term epilepsy-associated tumours, focal cortical dysplasias, vascular malformations, encephalitis including limbic and Rasmussen's encephalitis, gyral scarring including ulegyria) are detailed in the second section of this paper.

Epileptic seizures have been known from time immemorial. Throughout the ages, however, ideas concerning the aetiology and treatment of epilepsy have changed considerably. Epilepsy is mentioned many times in the Pentateuch, where it is portrayed as a mysterious condition, whose symptoms, course and contingencies evade rational laws and explanations. In the Middle Ages, the accepted view which prevailed in social consciousness was that patients with epilepsy were possessed by Satan and other impure spirits. One common method of treatment of epileptic seizures was to submit the patient to cruel exorcisms. Patients were frequently injured in the process and some of them even died. Our understanding of epilepsy and its social consequences has improved considerably within the last century. The most significant progress as far as diagnosis and treatment of epilepsy is concerned took place in the last four decades of the twentieth century. Although we now know much more about epilepsy than we used to, this knowledge is still insufficiently popularized.

Juvenile myoclonic epilepsy as a spectrum disorder: A focused review.

Science.gov (United States)

Baykan, Betül; Wolf, Peter

2017-07-01

In consequence of newer research juvenile myoclonic epilepsy (JME) is no longer seen as a homogeneous disease. The causes of the existing variance are only partially known yet. We discuss to what extent the phenotypical spectrum of this polygenetically determined disorder expresses genetically defined endophenotypes, or is due to mere quantitative differences in the expression of the core phenotype. Of the three common seizure types of JME, myoclonic, generalized tonic-clonic and absences, absences also occur independently and are strong candidates for an endophenotype. Focal features may in some patients be seen in clinical seizures or the EEG but rarely in both. They have no morphological correlates. In a system epilepsy, local manifestations are possible, and some are due to reflex mechanisms. Of the four reflex epileptic traits common in JME, photosensitivity and praxis induction appear related to basic mechanisms of the core syndrome, whereas language-induced orofacial reflex myocloni and eye closure sensitivity are also seen in other clinical contexts and therefore seem to represent endophenotypes. Cognitive abnormalities indicating slight frontal lobe dysfunction seem to be ubiquitous in JME and are also seen in unaffected siblings of patients. Cluster B personality disorder is found in 1/3 of patients, representing a more severe expression of the underlying pathology. Treatment response and prognosis seem to be affected by an interplay of the described factors producing the severest end of the JME spectrum. The spectrum appears to be due to an interaction of stronger or weaker expression of the core phenotype with various endophenotypes. Copyright © 2017 British Epilepsy Association.

Epilepsy is one of the most common neurological disorders. Global neurological knowledge is essential for differential diagnosis of epileptic syndromes due to the diversity of ictal semiology, causes and syndromes. Neurologists play an important role in planning the medical care for patients with epilepsy, as medication is the most fundamental therapeutic strategy. Some patients with early-onset epilepsy require joint care by pediatric neurologists, those with intractable epilepsy by neurosurgeons, and those with psychological comorbidity by psychiatrists, and neurologists should play a coordinating role. While there is a great need for neurologists to participate in epilepsy care, neurologists in Japan currently do not participate substantially in the epilepsy management system. It is necessary to train more neurologists who can provide epilepsy care and conduct basic and clinical research on epilepsy by providing continuous education on epilepsy for general neurologists as well as pre- and post-graduate medical students. Most of the patients who require long-term treatment experience many medical problems and social handicaps, such as adverse effects of medication, social stigma, educational disadvantages and difficulties in obtaining driver's license. To improve the quality of life of patients with epilepsy, it is desirable to build broad medical-social networks participated by patients, doctors, neurological nurses, psychologists, social workers, school teachers, managers of employment support facilities and care givers.

For youth with epilepsy, comorbid psychiatric conditions, such as depression and anxiety, require further examination as they carry increased risk for reduced health-related quality of life (HRQOL). The current study assessed whether rates of depression, anxiety, and withdrawal behaviors differed based on seizure location. Data included parental ratings on the Behavior Assessment System for Children (BASC-2) and the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire for 132 children and adolescents (mean age=11.34, SD=3.95) with generalized or partial (i.e., frontal [FLE] or temporal lobe epilepsy [TLE]) epilepsy. Our results identified clinically significant internalizing psychopathology in nearly half of our sample (41%). Although rates of internalizing behavior were similar between generalized and partial groups, children and adolescents with TLE demonstrated higher rates of depression compared to youth with FLE. No effects of laterality on internalizing behaviors were identified between TLE and FLE groups. Finally, for youth with TLE, parental depression ratings along with current number of antiepileptic medications (AEDs) were found to be significant barriers to HRQOL above and beyond anxiety, withdrawal, and epilepsy-specific variables. Temporal lobe epilepsy was associated with a two-fold risk of clinically significant depression ratings. These findings highlight the high prevalence of internalizing psychopathology features in pediatric epilepsy and offer further support for the relationship between depression and TLE in children and adolescents with epilepsy.

Spike-wave discharges, underlying absence seizures, are generated within a cortico-thalamo-cortical network that involves the somatosensory cortex, the reticular thalamic nucleus, and the ventrobasal thalamic nuclei. Activation of T-type voltage-sensitive calcium channels (VSCCs) contributes to the

Injuries in epilepsy: a review of its prevalence, risk factors, type of injuries and prevention

Full Text Available Currently, there is intense clinical research into various aspects of the medical risks relating to epilepsy, including total and cause-specific mortality, accidents and injuries in patients with epilepsy and mortality related with seizures. Seizures occurring in precarious situations and resulting in injuries are still an important concern for patients with epilepsy, their employers and their caregivers. Submersion injuries, motor vehicle accidents, burns, and head injuries are among the most feared epilepsy-related injuries. These concerns seem valid because the hallmark of epilepsy, episodic impairment of consciousness and motor control, may occur during interictal EEG epileptiform discharges, even in the absence of a clinical seizure. In addition, psychomotor comorbidity and side effects of antiepileptic drugs may contribute to the risk of injuries in patients with epilepsy. Published risk factors for injuries include the number of antiepileptic drugs, history of generalized seizures, and seizure frequency. In general, epidemiological information about incidence of injuries has been conflicting and sparse. In general, studies focusing on populations with more severe forms of epilepsy tend to report substantially higher risks of injuries than those involving less selected populations. On the other hand, studies based on non-selected populations of people with epilepsy have not shown an increased frequency of injuries in people with epilepsy compared with the general population. Some studies have shown that patients with epilepsy are more frequently admitted to the hospital following an injury. Possible explanations include: more cautious attitude of clinicians toward injuries occurring in the setting of seizures; hospitalization required because of seizures and not to the injuries themselves; and hospitalization driven by other issues, such as comorbidities, which are highly prevalent in patients with epilepsy. Potentially the high rate of

Recurrent diarrhea as a manifestation of temporal lobe epilepsy

Full Text Available A woman with temporal lobe epilepsy manifesting with repeated episodes of sudden diarrhea and loss of consciousness is reported. A 63-year-old, right-handed female presented with chief complaints of sudden diarrhea and loss of consciousness for almost three decades. The first attack occurred in her 30s, and similar attacks repeated several times in a year. Her attacks comprised abrupt abdominal discomfort, diarrhea, sudden emergence of old memories relating to when she had played with her brother in her childhood, and loss of consciousness during defecation. She had no convulsion or automatism and fully recovered in a few minutes. Every time she was transferred to emergency hospital by ambulance, she had examinations such as blood test, head computed tomography, electrocardiogram, abdominal ultrasound, and electroencephalography (EEG, but no specific diagnosis was made. On admission to our hospital, vital signs, neurological examination, and blood tests did not show abnormal findings. During long-term video-EEG monitoring for 40 h, she had no habitual event. Interictal EEG showed intermittent irregular delta waves and sharp regional transients in the left anterio-midtemporal area. Sharp transients were not as outstanding from background activities as to be defined as epileptiform discharges, but they were reproducible in morphology and distribution and appeared not only in sleep but also in wakefulness. Brain magnetic resonance imaging was unremarkable. Single-photon emission computed tomography showed a decrease of blood flow in the left frontal and temporal lobes. Wechsler Adult Intelligence Scale—III showed a decline of verbal comprehension. We concluded that the patient was suffering from partial epilepsy originating from the left temporal lobe. Carbamazepine markedly improved her seizures. Temporal lobe epilepsy can manifest with diverse autonomic symptoms and signs. Abdominal sensations often herald the onset of epileptic seizures

Epilepsy after stroke

Development of epilepsy was studied prospectively in a group of 77 consecutive stroke patients. Included were stroke patients less than 75 years old admitted within the first 3 days after the stroke. Excluded were patients with subarachnoid hemorrhage, vertebrobasilar stroke, and patients...... with other severe diseases. Cerebral angiography, CT, and EEG were performed in all patients. The patients were followed clinically for 2 to 4 years. Seven patients (9%) developed epilepsy. Of 23 patients with lesions involving the cortex, 6 (26%) developed epilepsy. Of 54 patients in whom the cortex...... was not involved, only 1 (2%) developed epilepsy. Patients with persisting paresis and cortical involvement seem to be at particularly high risk of developing epilepsy, as 50% of such patients (6 of 12) developed the disease....

Our objective was to examine the relationships of factors associated with children's emotional well-being 2 years after diagnosis, and to examine if these relationships are mediated or moderated by family factors. Data came from a multicenter prospective cohort study of children with newly diagnosed epilepsy from across Canada (Health-Related Quality of Life in Children with Epilepsy Study; HERQULES, n = 373). Emotional well-being was assessed using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55). The relationships between clinical factors, family factors, and emotional well-being were assessed using multiple regression analyses. Family functioning, family stress, and repertoire of resources that the families had to adapt to stressful events were significantly associated with poor emotional well-being 2 years after diagnosis (p < 0.05) in the multivariable analysis. The effect of parental depressive symptoms was partially mediated by family functioning and family stress (p < 0.01 and p = 0.02, respectively). Family resources acted as a moderator in the relationship between severity of epilepsy and emotional well-being (p < 0.05). Based on our findings, efforts to strengthen the family environment may warrant attention. We suggest that clinicians take a family centered care approach by including families in treatment planning. Family centered care has been shown to improve family well-being and coping and in turn may reduce the impact of clinical factors on emotional well-being to improve long-term health-related quality of life.

Epilepsy and Mood Disorders

Sermin Kesebir

2012-03-01

Full Text Available Mood disorders are the most common psychiatric comorbid disorder that affects quality of life and prognosis in epilepsy. The relation between depression and epilepsy is bidirectional. Not only the risk of having a depression among epilepsy cases is more than the healthy control cases, but also the risk of having epilepsy among depressive cases is more than the healthy control cases. People diagnosed with epilepsy are five times more likely than their peers to commit suicide. Moreover it seems that some epilepsy types like temporal lobe epilepsy have a much higher risk (25 times for suicide. Risk of suicide in epilepsy, which is independent from depression, increases more with the presence of depression. The common pathway between epilepsy, depression and suicide is hypofrontality and irregularity of serotonin metabolism. Contrary to depression, data on relationship between bipolar disorder and epilepsy is limited. However, mood disorder, mixed episodes with irritable character and mania are more frequent than assumed. As a matter of fact, both disorders share some common features. Both are episodic and can become chronic. Kindling phenomenon, irregularities in neurotransmitters, irregularities in voltage gate ion channels and irregularities in secondary messenger systems are variables that are presented in the etiologies of both disorders. Anticonvulsant drugs with mood regulatory effects are the common points of treatment. Understanding their mechanisms of action will clarify the pathophysiological processes. In this article, the relationhip between epilepsy and mood disorders, comorbidity, secondary states and treatment options in both cases have been discussed.

Children and adolescents with epilepsy often show higher rates of anxiety, which carries an increased risk for reduced health-related quality of life (HRQOL). The current study assessed the role of parental psychiatric history (i.e., anxiety, depression, and/or bipolar disorder) on the rate of anxiety features in youth seen in a tertiary epilepsy clinic. Data included parental ratings on the Behavior Assessment System for Children (BASC-2) and the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire for 180 children and adolescents (mean age=11.40, SD=3.98). Our results identified clinically elevated anxiety ratings in nearly half the sample (47%) with previous psychiatric history endorsed by 48% of parents. The effect of parental psychiatric history on youth anxiety was found to be significant and associated with a threefold increase in the rate of youth anxiety features. This risk increased to fourfold in refractory epilepsy, and the impact of family psychiatric history is greater in adolescent females and in families that report higher levels of stress. In those families who reported no psychiatric history, anxiety was best predicted by epilepsy-specific factors above and beyond sociodemographic factors. Parental psychiatric history was also identified as a significant risk factor for diminished patient HRQOL, even after accounting for seizure control. These findings highlight the impact of family and epilepsy factors on psychological functioning and offer further support for the strong relationship between parental adjustment and child outcome in pediatric epilepsy.

Positron emission tomography (PET) with [ 18 F]fluoro-D-deoxyglucose (FDG) has been used to detect seizure foci and evaluate surgical resection with localization related epilepsies. However, few investigations have focused on generalized epilepsy in children. To reveal the pathophysiology of generalized epilepsy, we studied 11 patients with generalized epilepsy except West syndrome, and 11 patients with localization related epilepsy without organic disease. The FDG PET was performed by simultaneous emission and transmission scanning. We placed regions of interest (ROI) on bilateral frontal lobe, parietal lobe, occipital lobe, temporal lobe, basal ganglia, thalamus and cerebellum. Standardized uptake value (SUV) was measured and normalized to SUV of ipsilateral cerebellum. Then, we compared the data of generalized epilepsy to those of localization related epilepsy. FDG PET revealed significant interictal glucose hypometabolism in bilateral basal ganglia in generalized epilepsy compared to that in localization related epilepsy (right side: p=0.0095, left side: p=0.0256, Mann-Whitney test). No other region showed any significant difference (p>0.05) between the two groups. These findings indicate that the basal ganglia is involved in the outbreak of generalized seizures or is affected secondarily by the epileptogenicity itself. (author)

Birth weight is an important indicator of prenatal/in-utero environment. Variations in birth weight have been reportedly associated with risks for cognitive problems. The National Longitudinal Survey of Children and Youth (NLSCY) dataset was explored to examine relationships between birth weight, academic school readiness and epilepsy. A population based sample of 32,900 children of the NLSCY were analyzed to examine associations between birth weight, and school readiness scores in 4-5-year-old children. Logistic and Linear regression was used to examine associations between having epilepsy and these outcomes. Gestation data was available on 19,867 children, full-term children represented 89.67% (gestation >259days), while 10.33% of children were premature (gestation children with reported epilepsy in the sample. Effects of confounding variables (diabetes in pregnancy, smoking in pregnancy, high blood pressure during pregnancy, and gender of the infant) on birth weight and epilepsy were controlled using a separate structural equation model. Logistic regression analysis identified an association between epilepsy and lower birth weights, as well as an association between lower birth weight, having epilepsy and lower PPVT-R Scores. Model results show the relationship between low birth weight and epilepsy remains statistically significant even when controlling for the influence of afore mentioned confounding variables. Low birth weight appears to be associated with both epilepsy and academic school readiness. The data suggest that an abnormal prenatal environment can influence both childhood onset of epilepsy and cognition. Additional studies with larger sample sizes are needed to verify this relationship in detail. Copyright © 2017 Elsevier B.V. All rights reserved.

Epilepsy affects people in all ages with the highest incidence in small children, particularly before age one year, and in elderly aged 65 years and older. In Sweden, between 4500-5000 persons develop epilepsy annually. Based on studies from North America and Europe, including the Nordic countries, the number of people with active epilepsy in Sweden is between 60000-70000. The lifetime risk for epilepsy up to age 85 years is 4-5 %, i.e. approximately every 25th person. The new epilepsy classification divides etiology into the following groups: structural, genetic, infectious, metabolic, immune and unknown. The majority (70%) of people with epilepsy eventually become seizure free. Epilepsy increases the risk of psychosocial problems and accidents. People with epilepsy have up to a 3-fold increase in mortality, mainly due to the underlying causes and epilepsy related deaths, e.g. status epilepticus, SUDEP and accidents. Somatic, psychiatric and neuropsychiatric comorbidities are common in epilepsy.

The purpose of this study was to characterize 132 children and adolescents (mean age = 10 years, 11 months) with epilepsy in terms of psychosocial functioning and to determine the extent to which adaptive skills and psychological functioning predict health-related quality of life (HRQOL), above and beyond demographic and epilepsy-specific characteristics. A chart review was conducted to obtain demographic and epilepsy-specific information as well as caregiver responses on the Behavior Assessment System for Children, Second Edition (BASC-2) Parent Report and the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). In addition to Full Scale IQ and age at seizure onset, the BASC-2 Clinical and Adaptive Skills subscales also predicted HRQOL, indicating that this measure may be particularly helpful in predicting HRQOL above and beyond information routinely collected in a medical setting. It is imperative to evaluate children with epilepsy for psychosocial difficulties and diminished HRQOL to ensure the provision of comprehensive quality care and intervention services.

Father absence and reproduction-related outcomes in Malaysia, a transitional fertility population.

Sheppard, Paula; Snopkowski, Kristin; Sear, Rebecca

Father absence is consistently associated with children's reproductive outcomes in industrialized countries. It has been suggested that father absence acts as a cue to particular environmental conditions that influence life history strategies. Much less is known, however, about the effects of father absence on such outcomes in lower-income countries. Using data from the 1988 Malaysian Family Life Survey (n = 567), we tested the effect of father absence on daughters' age at menarche, first marriage, and first birth; parity progression rates; and desired completed family size in Malaysia, a country undergoing an economic and fertility transition. Father absence during later childhood (ages 8 to 15), although not during earlier childhood, was associated with earlier progressions to first marriage and first birth, after controlling for other confounders. Father absence does not affect age at menarche, desired family size, or progression from first to second birth. The patterns found in this transitional population partly mirror those in developed societies, where father absence accelerates reproductive events. There is, however, a notable contrast between the acceleration in menarche for father-absent girls consistently found in developed societies and the lack of any association in our findings. The mechanisms through which father absence affects reproduction may differ in different ecological contexts. In lower-income contexts, direct paternal investment or influence may be of more importance in determining reproductive behavior than whether fathers act as a cue to environmental conditions.

Previous studies have documented associations between mental and physical health problems in cross-sectional studies, yet little is known about these relationships over time or the specificity of these associations. The aim of the current study was to examine the relationship between mental health problems in childhood at age 8 years and physical disorders in adulthood at ages 18-23 years. Multiple logistic regression analyses were used to examine the relationship between childhood mental health problems, reported by child, parent and teacher, and physical disorders diagnosed by a physician in early adulthood. Significant linkages emerged between childhood mental health problems and obesity, atopic eczema, epilepsy and asthma in early adulthood. Specifically, conduct problems in childhood were associated with a significantly increased likelihood of obesity and atopic eczema; emotional problems were associated with an increased likelihood of epilepsy and asthma; and depression symptoms at age 8 were associated with an increased risk of asthma in early adulthood. Our findings provide the first evidence of an association between mental health problems during childhood and increased risk of specific physical health problems, mainly asthma and obesity, during early adulthood, in a representative sample of males over time. These data suggest that behavioral and emotional problems in childhood may signal vulnerability to chronic physical health problems during early adulthood.

Epilepsy is one of the most prevalent chronic disorders of childhood which can threaten child development and mental health. Among cognitive disorders, dyscalculia is one of the most important. In this study, 39 children and adolescents with idiopathic epilepsy underwent clinical and neuropsychological assessment to determine the intellectual level, math skills, reading and writing performance and neuropsychological profile. It was observed that the mathematical ability was below schooling expectations in a higher frequency than expected. There were no significant differences in mathematical performance among groups divided by number of antiepileptic drugs used, duration of disease and types and frequency of seizures. There was a positive correlation with intelligence quotient and attentional and reading level. These results suggest the existence not only of dyscalculia, but the concurrence of attentional and reading problems for the poor mathematical performance in this population.

Childhood epilepsy is common in Africa. However, there are little data on the developmental and behavioral problems experienced by children living with epilepsy, especially qualitative data that capture community perceptions of the challenges faced by these children. Identifying these perceptions using qualitative approaches is important not only to help design appropriate interventions but also to help adapt behavioral tools that are culturally appropriate. We documented the description of these problems as perceived by parents and teachers of children with or without epilepsy. The study involved 70 participants. Data were collected using in-depth interviews and focus group discussions and were analyzed using NVIVO to identify major themes. Our analysis identified four major areas that are perceived to be adversely affected among children with epilepsy. These included internalizing and externalizing problems such as aggression, temper tantrums, and excessive crying. Additionally, developmental delay, especially cognitive deficits and academic underachievement, was also identified as a major problematic area. There is a need to supplement these findings with quantitative estimates and to develop psychosocial and educational interventions to rehabilitate children with epilepsy who have these difficulties.

Severe childhood epilepsies are characterized by frequent seizures, neurodevelopmental delays, and impaired quality of life. In these treatment-resistant epilepsies, families often seek alternative treatments. This survey explored the use of cannabidiol-enriched cannabis in children with treatment-resistant epilepsy. The survey was presented to parents belonging to a Facebook group dedicated to sharing information about the use of cannabidiol-enriched cannabis to treat their child's seizures. Nineteen responses met the following inclusion criteria for the study: a diagnosis of epilepsy and current use of cannabidiol-enriched cannabis. Thirteen children had Dravet syndrome, four had Doose syndrome, and one each had Lennox-Gastaut syndrome and idiopathic epilepsy. The average number of antiepileptic drugs (AEDs) tried before using cannabidiol-enriched cannabis was 12. Sixteen (84%) of the 19 parents reported a reduction in their child's seizure frequency while taking cannabidiol-enriched cannabis. Of these, two (11%) reported complete seizure freedom, eight (42%) reported a greater than 80% reduction in seizure frequency, and six (32%) reported a 25-60% seizure reduction. Other beneficial effects included increased alertness, better mood, and improved sleep. Side effects included drowsiness and fatigue. Our survey shows that parents are using cannabidiol-enriched cannabis as a treatment for their children with treatment-resistant epilepsy. Because of the increasing number of states that allow access to medical cannabis, its use will likely be a growing concern for the epilepsy community. Safety and tolerability data for cannabidiol-enriched cannabis use among children are not available. Objective measurements of a standardized preparation of pure cannabidiol are needed to determine whether it is safe, well tolerated, and efficacious at controlling seizures in this pediatric population with difficult-to-treat seizures. © 2013.
