For children with intractable epilepsy, surgery provides significant reduction in seizure frequency, with no significant declines in intellectual or behavioral functioning (Datta, et al., 2011). Prior to surgery, children must undergo a thorough assessment to determine the location of the seizure-focus and to evaluate risks of post-operative impairment (Lee, 2010). Currently, fMRI offers one of the most reliable and least invasive means of localizing language prior to surgery (McDonald, Saykin, William & Assaf, 2006). Dichotic listening, a behavioral task in which subjects are asked to listen to two competing stimuli simultaneously, offers a possible alternative for children who cannot complete fMRI studies. Previous studies have relied on research-based listening tasks and the type of quantitative analysis of the fMRI rarely available in the clinical setting. Instead, this study examined how well dichotic listening results predict language lateralization from fMRI within a clinical setting. Data were gathered through a records review of 13 children with intractable epilepsy referred to Austin Neuropsychology through the epilepsy treatment team at Dell Children’s Medical Center. Overall, children classified as atypical language dominance on the fMRI studies showed lower levels of right ear advantage on the dichotic listening measure. Despite this trend, a discriminant analysis using the dichotic listening results to predict fMRI classification showed no significant improvement over chance classification. A secondary analysis examined factors related to a child’s ability to complete an fMRI language study, comparing 12 children from the original sample with 6 children referred through the same process and over the same time period who could not obtain a successful fMRI determination of language lateralization. Overall, children who successfully completed the fMRI language studies showed a trend of lower levels of difficulty with behavioral regulation and higher levels of intelligence. Although the non-significant results highlight the limitations of dichotic listening as a clinical tool, the failure rate within the total sample, along with the information about the roles of intelligence and behavioral regulation, may help spur the development of alternative methods of language lateralization. / text

Objectives: To validate the revised 12-item revised Neurological Disorders Depression Inventory-Epilepsy for Youth (NDDI-E-Y), a self-report screening tool for depressive symptoms tailored to youth ages 12–17 with epilepsy. Methods: Youth at two sites completed the NDDI-E-Y during a routine epilepsy visit. Youth at one site also completed the Children's Depression Inventory-2 (CDI-2). Seizure and demographic data were abstracted from the electronic medical record. Exploratory factor analyses were conducted. Internal consistency, area under the curve (AUC), and construct validity were assessed. Results: NDDI-E-Y questionnaires were analyzed for 143 youth. The coefficient for internal consistency for the NDDI-E-Y was 0.92. Factor analyses suggested a one-factor solution with all 12 items loading on the factor. The NDDI-E-Y was positively correlated with the CDI-2 (N = 99). Sensitivity and specificity of the NDDI-E-Y were high. Significance: Reliability and construct validity were established for the revised 12-item NDDI-E-Y. The NDDI-E-Y is a brief, free measure of depressive symptoms that can be administered during a routine epilepsy visit.

Thesis advisor: Judith A. Vessey / Background: Parents of children with epilepsy and other neurological conditions live with a feeling of constant uncertainty. The uncertainty associated with caring for a child with epilepsy and other neurological conditions produces stress, which leads to decreased parental belief in caregiving skills, anxiety, and depression, ultimately altering parental functioning resulting in an increase in child behavioral problems. The stress associated with caring for a child with epilepsy and other neurological conditions is unlike caring for children with other chronic conditions. Epilepsy and other neurological conditions are unpredictable and there are often no warning signs prior to an acute event. This unpredictability accompanied with stigma results in social isolation and impacts family functioning. In addition, children with epilepsy have a higher rate of psychological co-morbidities and behavior problems when compared to children with other chronic conditions. This produces an additional burden on the parents and family. Study Design: This randomized controlled trial tested the efficacy of the COPE intervention for parents of children with epilepsy and other neurological conditions. This intervention was administered at three intervals: 1) during hospital admission in writing and by audiotape, MP3 download, or Podcast; 2) three days following hospital discharge by telephone; and 3) four to six weeks after hospital discharge in writing and by audiotape, MP3 download, or Podcast. Results: Forty-six parents of children admitted to the inpatient neuroscience unit at Boston Children's Hospital participated in the study. Several study limitations resulted in an inadequate sample size to obtain the power necessary to reach statistically significant results for a majority of the research questions. A one-between, one-within multivariate analysis of variance (MANOVA) revealed that the main effect of time was significant for differences in state anxiety for both the Usual Care Group and the Intervention Group, F, (1, 20) = 9.86, p = .005, indicating that state anxiety for both groups combined was more pronounced during the hospitalization. A one-between, one-within MANOVA demonstrated that the effect of the interaction between time and group was significant for internalized behavior assessment system score only (p=.037) as the Usual Care Group reported a significant decrease in internalizing behavior scores in their children over time. Conclusions: Findings from this study have significant implications for clinical practice and future research. Parents of children with neurological conditions often struggle to manage a constant feeling of uncertainty in their daily lives. Nurses possess the knowledge and expertise necessary to identify the psychosocial needs of these parents and provide education and support as needed. Future research should focus on designing interventions to meet the needs of these families and develop strategies to help improve the quality of life for both the parent and child living with a neurological condition. / Thesis (PhD) — Boston College, 2013. / Submitted to: Boston College.

The primary objective of this proposal was to determine whether mitochondrial oxidative stress and variation in a particular mtDNA lineage contribute to the risk of developing cortical dysplasia and are potential contributing factors in epileptogenesis in children. The occurrence of epilepsy in children is highly associated with malformations of cortical development (MCD). It appears that MCD might arise from developmental errors due to environmental exposures in combination with inherited variation in response to environmental exposures and mitochondrial function. Therefore, it is postulated that variation in a particular mtDNA lineage of children contributes to the effects of mitochondrial DNA damage on MCD phenotype. Quantitative PCR and dot blot were used to examine mitochondrial oxidative damage and single nucleotide polymorphism (SNP) in the mitochondrial genome in brain tissue from 48 pediatric intractable epilepsy patients from Miami Children’s Hospital and 11 control samples from NICHD Brain and Tissue Bank for Developmental Disorders. Epilepsy patients showed higher mtDNA copy number compared to normal health subjects (controls). Oxidative mtDNA damage was lower in non-neoplastic but higher in neoplastic epilepsy patients compared to controls. There was a trend of lower mtDNA oxidative damage in the non-neoplastic (MCD) patients compared to controls, yet, the reverse was observed in neoplastic (MCD and Non-MCD) epilepsy patients. The presence of mtDNA SNP and haplogroups did not show any statistically significant relationships with epilepsy phenotypes. However, SNPs G9804A and G9952A were found in higher frequencies in epilepsy samples. Logistic regression analysis showed no relationship between mtDNA oxidative stress, mtDNA copy number, mitochondrial haplogroups and SNP variations with epilepsy in pediatric patients. The levels of mtDNA copy number and oxidative mtDNA damage and the SNPs G9952A and T10010C predicted neoplastic epilepsy, however, this was not significant due to a small sample size of pediatric subjects. Findings of this study indicate that an increase in mtDNA content may be compensatory mechanisms for defective mitochondria in intractable epilepsy and brain tumor. Further validation of these findings related to mitochondrial genotypes and mitochondrial dysfunction in pediatric epilepsy and MCD may lay the ground for the development of new therapies and prevention strategies during embryogenesis.

Understanding pathways of neurological disorders requires extensive research on both functional and structural characteristics of the brain. This dissertation introduced two interrelated research endeavors, describing (1) a novel integrated approach for constructing functional connectivity networks (FCNs) of brain using non-invasive scalp EEG recordings; and (2) a decision aid for estimating intracranial volume (ICV). The approach in (1) was developed to study the alterations of networks in patients with pediatric epilepsy. Results demonstrated the existence of statistically significant (p

The purpose of this study was to examine the feasibility of a behavioral health referral protocol and barriers to behavioral health care in a pediatric epilepsy clinic. A sample of 93 youth with epilepsy ages 10–17 and caregivers completed behavioral health and seizure severity measures during a routine epilepsy clinic visit. Key findings are that 47 (50.5%) of the youth screened positive for a behavioral health referral, and 35 of these youth were referred for behavioral health services. However, only 20% made and presented for the behavioral health appointment. The most commonly cited barrier for accessing and utilizing behavioral health care was stigma related- a mental health label for the child. The significance of this study lies in the revelation that solely screening for and educating caregivers about behavioral health symptoms and providing behavioral health referral information is not an ideal model. Instead, stigma related barriers point to the necessity of continued integrated physical and behavioral health care within the pediatric epilepsy visit.

Objective: Proper assessment and early identification of depressive symptoms are essential to initiate treatment and minimize the risk for poor outcomes in youth with epilepsy (YWE). The current study examined the predictive utility of the Neurological Disorders Depression Inventory-Epilepsy for Youth (NDDI-E-Y) and the Neuro-QOL Depression Short Form (Neuro-QOL SF) in explaining variance in overall depressive symptoms and specific symptom clusters on the gold standard Children's Depression Inventory-2 (CDI-2). Methods: Cross-sectional study examining 99 YWE (female 68, mean age 14.7 years) during a routine epilepsy visit, who completed self-report measures of depressive symptoms, including the NDDI-E-Y, CDI-2, and the Neuro-QOL SF. Caregivers completed a measure of seizure severity. All sociodemographic and medical information was evaluated through electronic medical record review. Results: After accounting for seizure and demographic variables, the NDDI-E-Y accounted for 45% of the variance in the CDI-2 Total score and the CDI-2 Ineffectiveness subscale. Furthermore, the NDDI-E-Y predicted CDI-2 Total scores and subscales similarly, with the exception of explaining significantly more variance in the CDI-2 Ineffectiveness subscale compared to the Negative Mood subscale. The NDDI-E-Y explained greater variance compared to Neuro-QOL SF across the Total (48% vs. 37%) and all CDI-2 subscale scores; however, the NDDI-E-Y emerged as a stronger predictor of only CDI-2 Ineffectiveness. Both the NDDI-E-Y and Neuro-QOL SF accounted for the lowest amount of variance in CDI-2 Negative Mood. Sensitivity was poor for the Neuro-QOL SF in predicting high versus low CDI-2 scores. Significance: The NDDI-E-Y has strong psychometrics and can be easily integrated into routine epilepsy care for quick, brief screening of depressive symptoms in YWE.

Fundamentação e Objetivo: A epilepsia é a doença neurológica mais comum em crianças. A avaliação da qualidade de vida destas crianças é importante para otimizar o tratamento delas. É importante para obter os pontos de vista das próprias crianças e seus pais. No entanto, existem poucos instrumentos que avaliem a qualidade de vida através da visão das crianças e dos seus pais. O objetivo deste estudo foi desenvolver e validar uma nova ferramenta para avaliação da qualidade de vida em crianças com epilepsia através de seus pais e dos pacientes. Material e Métodos: Baseada no trabalho anterior de Arunkumar e colaboradores, foi elaborada uma escala de múltipla escolha com 20 questões independentes para as crianças e seus pais: A Quality-of-Life in Pediatric Epilepsy Scale (QLPES). A análise fatorial com rotação VARIMAX foi usada para identificar possíveis áreas para as 20 questões propostas e alfa de Cronbach foi utilizado para testar a consistência das escalas. As respostas dadas pelos pacientes e seus pais ou cuidadores foram correlacionadas com frequência e gravidade das crises e com outras variáveis relacionadas com a epilepsia. Resultados: No total, 171 pacientes e seus pais participaram deste estudo. Setenta e quatro pacientes (43,3%) eram do sexo feminino, com médias de 13,3 (DP = 3,0) anos de idade e de 5,1 (DP = 3,1) anos de escolaridade. O alfa de Cronbach para cada domínio isolado sugerido pela analise fatorial foi abaixo de 0,7 para cada grupo. Entretanto, o alfa de Cronbach para todas as perguntas na escala dos pais foi de 0,83, e de 0,74 para as crianças. Para os pais ou cuidadores, as pontuações do QLPES foram menores para as mães/cuidadoras, para as crianças que usavam dois ou mais medicamentos antiepilépticos, para crianças com mais tempo de epilepsia, com maior duração de crises, ou aquelas com maior número de crises. Para as crianças, a pontuação QLPES foi menor para pacientes do sexo feminino, para as crianças que usavam dois ou mais medicamentos antiepilépticos, para aquelas com maior frequência de crises, e para crianças com EEG normal. Conclusão: A QLPES apresenta validade interna, consistência interna, confiabilidade teste-reteste e boa sensibilidade. A QLPES é um instrumento útil, preciso, rápido e fácil de usar, que reflete adequadamente a forma como a epilepsia afeta a qualidade de vida de crianças/adolescentes, assim como ele reflete como a epilepsia pediátrica afeta a qualidade de vida dos pacientes na perspectiva de seus pais ou cuidadores. / Background and Purpose: Epilepsy is the most common neurological condition in children. The evaluation of the quality of life of these children is important to optimize the treatment of them. It is important to obtain the views of the children themselves and of their parents. However, there are few scales assessing quality of life through both. The purpose of this study was to develop and validate a new parent- and patient- tool for evaluating health-related quality-of-life in pediatric epilepsy. Design and Methods: Based on previous work of Arunkumar and colleagues, we created a multiple choice scale with 20 independent questions for children and their parents. The Quality-of-Life in Pediatric Epilepsy Scale (QLPES). Factor analysis with VARIMAX rotation was used to identify possible areas for the 20 proposed questions, and Cronbach's alpha was used to test the scale’s consistency. The answers given by patients and their parents or caregivers were correlated with frequency and severity of the seizures and with other epilepsy-related variables. Results: A total of 171 patients and their parents participated in this study. Seventy four (43.3%) patients were female, with mean of 13.3 (SD=3.0) years of age and 5.1 (SD=3.1) years of schooling. The Cronbach's alpha of isolated domains suggested by the factor analysis were less than 0.7 for each group. However, alpha Cronbach for all the questions in the parents’ scale was 0.83 and 0.74 for children. For parents or caregivers, QLPES scores were lower for females responders, for children using two or more antiepileptic drugs, for children with longer time of epilepsy, longer seizure duration, or those with higher number of seizures. For children, QLPES scores were lower for female patients, for children using two or more antiepileptic drugs, for those with higher frequency of seizures, and for children with normal EEG. Conclusion: QLPES exhibits internal validity, internal consistency, test–retest reliability, and good sensitivity. QLPES is a useful, accurate, brief and easy to use instrument that adequately reflects the way epilepsy affects the quality of life of children/adolescents, as well as it reflects how pediatric epilepsy affects quality of life in the perspective of their parents or caregivers.

Epilepsy represents the most common neurological disease, its prevalence reaching up to 1%, and around 30% of patients become refractory to treatment. In these patients, epilepsy surgery is often their only chance for disease-free life. Aetiology of epilepsy is heterogenous; we recognize genetic, structural- metabolic epilepsy and epilepsy with unknown aetiology. Patients with focal pharmacoresistant epilepsy may become candidates for epilepsy surgery; the same does not apply to patients with metabolic or neurodegenerative disease. Multiple factors influence decision about epilepsy surgery, the most important ones being (i) the type of known or presumed structural lesion and (ii) the possibility to precisely delineate the epileptogenic zone (the area of seizure generation). Another factor that needs to be accounted for is the proximity of epileptogenic zone to the eloquent cortical areas (the areas with important neurological functions, e.g. motor or speech functions). Epilepsy surgery principally aims for complete removal the epileptogenic zone, and subsequently for complete freedom from seizures. Hypothesis on the localization of the epileptogenic zone arises from the combined information gained from various diagnostic, mostly neuroimaging, methods. Cognitive profile examination includes...
