Fenfluramine below the age of 2 years in Dravet syndrome: What about safety and efficacy? Epilepsia 2024; 65:e7-e13. [PMID: 38065833 DOI: 10.1111/epi.17854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 12/06/2023] [Accepted: 12/07/2023] [Indexed: 12/22/2023]
Abstract
Dravet syndrome (DS) is a rare developmental and epileptic encephalopathy. Infants with DS are especially vulnerable to the detrimental effects of prolonged and frequent seizures on development. Fenfluramine (FFA) is approved for the treatment of DS in patients aged 2 years and older. This study aims to evaluate the safety and efficacy of FFA in patients with DS younger than 2 years. We analyzed safety, tolerability, seizure, and neuropsychological outcome in a real-world setting. Developmental profile was investigated using Griffiths Mental Development Scales (GMDS). Five patients received FFA at a mean age of 14.9 months (9.6-18.6). Median follow-up was 13 months (interquartile range [IQR] = 12.9-24.4). All patients showed good tolerance to FFA. No significant variation of body mass index or echocardiographic issue was observed. Monthly median convulsive seizure frequency (MCSF) was 1.71 (IQR = 1.56-3.27) at the 6-month baseline period and .92 (IQR = .43-1.28) at last follow-up, with a median 54.43 (IQR = 40.91-60.83) percentage reduction in MCSF. Two of five patients had a performance improvement on GMDS subscales. Overall, the use of FFA below the age of 2 years in our small sample of patients was safe and represents a promising opportunity for seizure control and for protection of the neurodevelopmental outcome.

Abstract
The cerebellum is involved in motor and non-motor functions. Cerebellar lesions can underlie the disruption of various executive functions. The violation of executive functions in cerebellar lesions is a serious problem, since children, after completing treatment, must return to school, finish their education, and get a profession. One of the important executive functions is working memory, which contributes to academic success. Deficits of verbal working memory in cerebellar tumors have been studied, in contrast to visual-spatial working memory. To assess this issue, 101 patients who survived cerebellar tumors and 100 healthy control subjects performed a visual-spatial working memory test. As a result, in children who survived cerebellar tumors, visual-spatial working memory is impaired compared to the control group. Moreover, with age, and hence the time since the end of treatment, the number of elements that children can retain in visual-spatial working memory increases, but still remains smaller compared to the control group. Our findings complement the idea of cerebellar involvement in visual-spatial working memory and suggest that it is disrupted by cerebellar lesions in children.

Abstract
The present study compared parent-rated executive functioning in pediatric medulloblastoma (MB) and pilocytic astrocytoma (PA) survivors. Although standard care for both includes surgical resection, children with MB additionally receive chemotherapy and craniospinal irradiation. Given well-documented neurocognitive late effects associated with the latter, we anticipated poor parent-reported executive functioning in MB survivors. Parents/guardians of 36 MB survivors and 20 PA survivors completed the Behavior Rating Inventory of Executive Functioning (BRIEF). PA survivors were younger at diagnosis (t[51.97] = 3.07, p < .001, d = 0.86) and demonstrated higher IQ (t[54] = -3.51, p < .001, d = 0.95). However, relative to the MB group, the PA group was rated as having significantly more problems on all BRIEF scales (all p ≤ .05; d = 0.30 - 1.10), except the Shift scale. Additionally, all mean BRIEF scores for MB survivors were within normal limits, whereas for PA survivors, all mean BRIEF scores except for Organization of Materials were significantly discrepant from normative means. Overall, PA survivors were rated as demonstrating poorer executive function than MB survivors. Five theories are discussed as possible explanations for these surprising findings: two related to group differences, two related to potential sources of parental bias, and one related to the nature of questionnaire-based assessment. All these theories represent directions for future research. Parent questionnaires such as the BRIEF may have real-world implications for pediatric brain tumor survivors. Future research should explore factors affecting parent ratings of executive functioning in these populations, along with comparison to performance-based measures.

Abstract
BACKGROUND Urea cycle disorders (UCDs) cause impaired conversion of waste nitrogen to urea leading to rise in glutamine and ammonia. Elevated ammonia and glutamine have been implicated in brain injury. This study assessed relationships between biomarkers of metabolic control and long-term changes in neuropsychological test scores in participants of the longitudinal study of UCDs. The hypothesis was that elevated ammonia and glutamine are associated with neuropsychological impairment. METHODS Data from 146 participants who completed 2 neuropsychological assessments were analyzed. Neuropsychological tests that showed significant changes in scores over time were identified and associations between score change and interim metabolic biomarker levels were investigated. RESULTS Participants showed a significant decrease in performance on visual motor integration (VMI) and verbal learning immediate-recall. A decrease in scores was associated with experiencing interim hyperammonemic events (HAE) and frequency of HAE. Outside of HAE there was a significant association between median ammonia levels ≥50µmol/L and impaired VMI. CONCLUSION VMI and memory encoding are specifically affected in UCDs longitudinally, indicating that patients experience difficulties when required to integrate motor and visual functions and learn new information. Only ammonia biomarkers showed a significant association with impairment. Preventing HAE and controlling ammonia levels is key in UCD management. IMPACT The Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI) and List A Trial 5 of the California Verbal Learning Test (CVLT) may be good longitudinal biomarkers of treatment outcome in urea cycle disorders (UCD). This is the first report of longitudinal biomarkers for treatment outcome in UCD. These two biomarkers of outcome may be useful for clinical trials assessing new treatments for UCD. These results will also inform educators how to design interventions directed at improving learning in individuals with UCDs.

Fenfluramine treatment is associated with improvement in everyday executive function in preschool-aged children (<5 years) with Dravet syndrome: A critical period for early neurodevelopment. Epilepsy Behav 2023; 138:108994. [PMID: 36463826 DOI: 10.1016/j.yebeh.2022.108994] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 10/29/2022] [Accepted: 11/05/2022] [Indexed: 12/03/2022]
Abstract
OBJECTIVE To evaluate whether fenfluramine (FFA) is associated with improvement in everyday executive function (EF)-self-regulation-in preschool-aged children with Dravet syndrome (DS). METHODS Children with DS received placebo or FFA in one of two phase III studies (first study: placebo, FFA 0.2 mg/kg/day, or FFA 0.7 mg/kg/day added to stiripentol-free standard-of-care regimens; second study: placebo or FFA 0.4 mg/kg/day added to stiripentol-inclusive regimens). Everyday EF was evaluated at baseline and Week 14-15 for children aged 2-4 years with parent ratings on the Behavior Rating Inventory of Executive Function®-Preschool (BRIEF®-P); raw scores were transformed to T-scores and summarized in Inhibitory Self-Control Index (ISCI), Flexibility Index (FI), Emergent Metacognition Index (EMI), and Global Executive Composite (GEC). Clinically meaningful improvement and worsening were defined using RCI ≥ 90% and RCI ≥ 80% certainty, respectively. The associations between placebo vs FFA combined (0.2, 0.4, and 0.7 mg/kg/day) or individual treatment groups and the likelihood of clinically meaningful change in BRIEF®-P indexes/composite T-scores were evaluated using Somers'd; pairwise comparisons were calculated by 2-sided Fisher's Exact tests (p ≤ 0.05) and Cramér's V. RESULTS Data were analyzed for 61 evaluable children of median age 3 years (placebo, n = 22; FFA 0.2 mg/kg/day, n = 15; 0.4 mg/kg/day [with stiripentol], n = 10; 0.7 mg/kg/day, n = 14 [total FFA, n = 39]). Elevated or problematic T-scores (T ≥ 65) were reported in 55% to 86% of patients at baseline for ISCI, EMI, and GEC, and in ∼33% for FI. Seventeen of the 61 children (28%) showed reliable, clinically meaningful improvement (RCI ≥ 90% certainty) in at least one BRIEF®-P index/composite, including a majority of the children in the FFA 0.7 mg/kg/day group (9/14, 64%). Only 53% of these children (9/17) also experienced clinically meaningful reduction (≥50%) in monthly convulsive seizure frequency, including 6/14 patients in the FFA 0.7 mg/kg/day group. Overall, there were positive associations between the four individual treatment groups and the likelihood of reliable, clinically meaningful improvement in all BRIEF®-P indexes/composite (ISCI, p = 0.001; FI, p = 0.005; EMI, p = 0.040; GEC, p = 0.002). The FFA 0.7 mg/kg/day group showed a greater likelihood of reliable, clinically meaningful improvement than placebo in ISCI (50% vs 5%; p = 0.003), FI (36% vs 0%; p = 0.005), and GEC (36% vs 0%; p = 0.005). For EMI, the FFA 0.7 mg/kg/day group showed a greater likelihood of reliable, clinically meaningful improvement than the FFA 0.2 mg/kg/day group (29% vs 0%; p = 0.040), but did not meet the significance threshold compared with placebo (29% vs 5%; p = 0.064). There were no significant associations between treatment and the likelihood of reliable, clinically meaningful worsening (p > 0.05). SIGNIFICANCE In this preschool-aged DS population with high baseline everyday EF impairment, FFA treatment for 14-15 weeks was associated with dose-dependent, clinically meaningful improvements in regulating behavior, emotion, cognition, and overall everyday EF. These clinically meaningful improvements in everyday EF were not entirely due to seizure frequency reduction, suggesting that FFA may have direct effects on everyday EF during the early formative years of neurodevelopment.

Preschool neurodevelopment in Zika virus-exposed children without congenital Zika syndrome. Pediatr Res 2022:10.1038/s41390-022-02373-5. [PMID: 36446920 PMCID: PMC10227180 DOI: 10.1038/s41390-022-02373-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 08/19/2022] [Accepted: 08/24/2022] [Indexed: 12/05/2022]
Abstract
BACKGROUND Children with in utero Zika virus (ZIKV) exposure without congenital Zika syndrome (CZS) are at risk for abnormal neurodevelopment. Preschool-age outcomes for children with antenatal ZIKV exposure have not yet been established. METHODS Children with in utero ZIKV exposure and non-exposed controls had neurodevelopmental evaluations at age 3-5 years in Sabanalarga, Colombia. Cases did not have CZS and were previously evaluated prenatally through age 18 months. Controls were born before ZIKV arrival to Colombia. Neurodevelopmental assessments included Pediatric Evaluation of Disability Inventory (PEDI-CAT), Behavior Rating Inventory of Executive Function (BRIEF-P), Bracken School Readiness Assessment (BSRA), and Movement Assessment Battery for Children (MABC). Family demographics and child medical history were recorded. RESULTS Fifty-five ZIKV-exposed children were evaluated at mean age 3.6 years and 70 controls were evaluated at 5.2 years. Family demographics were similar between groups. BRIEF-P t-scores were higher for cases than controls in shift and flexibility domains. Cases had lower PEDI-CAT mobility t-scores compared to controls. There was no difference in MABC between groups. In 11% of cases and 1% of controls, parents reported child mood problems. CONCLUSIONS Children with in utero ZIKV exposure without CZS may demonstrate emerging differences in executive function, mood, and adaptive mobility that require continued evaluation. IMPACT Preschool neurodevelopmental outcome in children with in utero Zika virus exposure is not yet known, since the Zika virus epidemic occurred in 2015-2017 and these children are only now entering school age. This study finds that Colombian children with in utero Zika virus exposure without congenital Zika syndrome are overall developing well but may have emerging differences in executive function, behavior and mood, and adaptive mobility compared to children without in utero Zika virus exposure. Children with in utero Zika virus exposure require continued multi-domain longitudinal neurodevelopmental evaluation through school age.

Abstract
Pediatric brain tumor survivors have more executive dysfunction than controls. White matter hyperintensities are positively associated with executive dysfunction. White matter hyperintensities are positively associated with apathy. Multivariate regression supports white matter hyperintensity associations. Survivors appear to drive white matter hyperintensities associations.
White matter hyperintensities (WMHs) have been related to executive dysfunction, apathy and disinhibition in a wide range of neurological populations. However, this relationship has not been examined in survivors of pediatric brain tumor. The goal of this study was to investigate how executive dysfunction, apathy, and disinhibition relate to WMHs in 31 long-term survivors of pediatric cerebellar brain tumor and 58 controls, using informant-report data from the Frontal Systems Behavior Scale. Total WMH volume was quantified using the Lesion Growth Algorithm. Further, periventricular, and subcortical volumes were identified based on proximity to custom ventricle masks generated in FSL. A ratio of WMH volume to whole brain volume was used to obtain normalized WMH volumes. Additionally, a multivariate regression analysis was performed. On average, informant-report scores were within normal limits and only executive dysfunction was significantly higher in survivors compared to controls (t(47.9) = -2.4, p=.023). Informants reported clinically significant levels of apathy in 32.3% of survivors. Informants also reported clinically significant executive dysfunction in 19.4 % of survivors and clinically significant disinhibition in, again, 19.4 % of survivors. Increased volume of WMHs was positively correlated with executive dysfunction (r = 0.33, p = 0.02) and apathy (r = 0.23, p = .04). Similarly, multivariate regression demonstrated correlations with executive dysfunction (p=.05, FDR corrected) and apathy (p=.05, FDR corrected). Exploratory analysis demonstrated an interaction wherein the relationship between total WMHs and executive dysfunction and apathy depends on whether the participant was a survivor. The current findings indicate that increased WMH volumes are associated with higher ratings of apathy and executive dysfunction, and that these results are likely unique to cerebellar brain tumor survivors. WMH burden may serve as a useful marker to identify survivors at risk of executive dysfunction or increased apathy.

Abstract
Adolescent survivors of pediatric brain tumor (PBT) are a sparsely studied subset of childhood cancer survivors. Sustaining a PBT may complicate the development of executive functions (EFs), which play a vital role in long-term psychosocial adjustment. In this study, 48 adolescent survivors and their parents completed questionnaires assessing EF, psychological symptoms, fatigue, and adaptive functioning, and 26 survivors underwent neuropsychological assessment. Survivors reported significantly more problems with adaptive functioning than a healthy control group, and this was most strongly associated to executive dysfunction, compared to psychological symptoms and fatigue. The findings have important implications for long-term follow-ups.

Abstract
OBJECTIVE To examine the predictive role of social skills in youth with spina bifida (SB) on growth in medical responsibility across development. METHODS As part of a larger, longitudinal study, 140 youth with SB were assessed across four time points (ages 8-22 across time points). Mixed-effects models were investigated for change with: (a) no predictors (i.e., change in medical responsibility across age; time was examined using the participant's age, centered at 11.5 years); (b) social variables (i.e., observed social behaviors, parent- and teacher-reported social skills) as predictors; and (c) social variables as predictors with intelligence quotient, lesion level, and sex as covariates. RESULTS Significant growth with age was identified for medical responsibility (p < .0001). Observed, parent-reported, and teacher-reported social skills did not significantly predict this growth; however, all three predicted the intercept for medical responsibility at 11.5 years of age (ps ≤ .047). Parent-reported social skills remained a significant predictor of the intercept at 11.5 years of age when including the covariates (p = .008). CONCLUSIONS Children with SB who exhibited more positive social skills were more likely to a have higher level of medical responsibility in late childhood, but higher levels of social skills were not associated with a more rapid increase in responsibility over time. Identifying existing social strengths and promoting the practice of prosocial skills may have additional benefits to children with SB, including their acquisition of medical responsibility.

Abstract
Adolescents with epilepsy are at risk for deficits in working memory, which could lead to learning difficulties and poor academic outcomes. We used task-based functional magnetic resonance imaging (fMRI) to examine potential disruption in working memory function in adolescents with epilepsy as compared to healthy controls. We recruited 29 adolescents (13-17 years) with non-lesional epilepsy and 20 healthy controls. All participants performed an N-back fMRI task and neuropsychological testing. A general linear model approach was used to create group activation maps of N-back fMRI for epilepsy and control groups and both groups combined (p < 0.05 corrected for multiple comparisons). Functionally defined regions of interest (ROIs) were identified based on clusters of combined group activation (z > 5). Subsets of these functional ROIs corresponding to cingulo-opercular and fronto-parietal networks were selected and differences in functional connectivity between the epilepsy and control groups were assessed. Adolescents with epilepsy had significantly poorer working memory scores compared to controls. For the N-back fMRI task, there were no significant differences in group activation. Functional connectivity was significantly reduced between the left frontal operculum and anterior cingulate gyrus (cingulo-opercular network) in adolescents with epilepsy compared to controls. This study demonstrates working memory deficits and an altered pattern of connectivity in brain networks supporting working memory in adolescents with epilepsy. Working memory performance was worse in adolescents with epilepsy; though scores were not directly correlated with reduced connectivity. These results suggest the neural substrates of working memory in adolescents with epilepsy may differ from those in typically-developing adolescents, and require further investigation to understand the reasons for poorer working memory performance.

Abstract
Over the past few decades, research has established that the cerebellum is involved in executive functions; however, its specific role remains unclear. There are numerous theories of cerebellar function and numerous cognitive processes falling under the umbrella of executive function, making investigations of the cerebellum's role in executive functioning challenging. In this review, we explored the role of the cerebellum in executive functioning through clinical and cognitive neuroscience frameworks. We reviewed the neuroanatomical systems and theoretical models of cerebellar functions and the multifaceted nature of executive functions. Using attention deficit hyperactivity disorder and cerebellar tumor as clinical developmental models of cerebellar dysfunction, and the functional magnetic resonance imaging literature, we reviewed evidence for cerebellar involvement in specific components of executive function in childhood, adolescence, and adulthood. There is evidence for posterior cerebellar contributions to working memory, planning, inhibition, and flexibility, but the heterogeneous literature that largely was not designed to study the cerebellum makes it difficult to determine specific functions of the cerebellum or cerebellar regions. In addition, while it is clear that cerebellar insult in childhood affects executive function performance later in life, more work is needed to elucidate the mechanisms by which executive dysfunction occurs and its developmental course. The limitations of the current literature are discussed and potential directions for future research are provided.

Investigation of the Clinical Utility of the BRIEF2 in Youth With and Without Intellectual Disability. J Int Neuropsychol Soc 2020; 26:1036-1044.

Abstract
OBJECTIVE Executive function (EF) difficulties are commonly found in youth with intellectual disability (ID). Given mixed results from studies using performance-based EF measures, the EF profile has not been well characterized for this population. No published work has examined the clinical utility of the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2) in distinguishing EF in ID. We hypothesized that the BRIEF2 would show greater elevations in youth with ID compared to the Average IQ comparison group. METHODS Participants included a large sample of 504 youth (157 in ID group; aged 8-18 years) referred for (neuro)psychological evaluation (2015-2019) and identified as meeting criteria for either ID or Average IQ comparison group. RESULTS Significant elevations were found across BRIEF2 indices and scales. Only mild elevations were noted in selective cognitive regulation scales within the Average IQ group. Groups differed significantly across all EF dimensions, with greater differences observed in behavioral regulation (Self-Monitoring, Inhibition), Shift, and Working Memory. An elevated but less variable pattern of index scores was noted in ID, while the overall pattern of scaled scores appeared similar between groups. CONCLUSIONS The less variable and consistently elevated profile may suggest fewer EF dimensions in individuals with ID than the model proposed in the test manual. Similar profiles between groups may reflect differences in severity, rather than differences in constructs measured by the EF factors, per se. Additional examination is needed to confirm potential structural differences in EF for youth with ID as measured by BRIEF2, with a clinical implication for greater efficiency of EF assessment in this population.

Abstract
OBJECTIVE The objective of the study was to report on the internal consistency reliability and discriminant, concurrent and construct validity of the Pediatric Quality of Life Inventory™ (PedsQL™) Cognitive Functioning Scale as a brief generic cognitive functioning measure in youth with epilepsy. METHODS The 6-item PedsQL™ Cognitive Functioning Scale and 23-item PedsQL™ 4.0 Generic Core Scales were completed by 221 pediatric patients ages 5-18 years with epilepsy and 336 parents of patients ages 2-18 years in a national field test study for the PedsQL™ Epilepsy Module. Parents also completed the 86-item Behavior Rating Inventory of Executive Function (BRIEF), a widely validated measure of executive functioning. RESULTS The PedsQL™ Cognitive Functioning Scale evidenced excellent reliability (patient self-report α = 0.88; parent proxy-report α = 0.96), distinguished between youth with epilepsy and an age, gender, and race/ethnicity-matched healthy sample supporting discriminant validity with large effect sizes (~20-30 point score differences, P < 0.001), and demonstrated concurrent and construct validity, respectively, through large effect size intercorrelations with the BRIEF (Behavioral Regulation Index, Metacognition Index, Global Executive Composite Summary Scores rs = 0.43-0.67, P < 0.001) and the PedsQL™ Generic Core Scales (Total Scale Scores rs = 0.67-0.74, P < 0.001). Minimal clinically important difference (MCID) scores ranged from 5.92 to 8.80. CONCLUSIONS The PedsQL™ Cognitive Functioning Scale demonstrated excellent internal consistency reliability, discriminant, concurrent, and construct validity in youth with epilepsy and may be suitable as a brief generic patient-reported outcome (PRO) measure for clinical research, clinical trials, and routine clinical practice in pediatric epilepsy.

Usefulness of preschool and school versions of the Behavioral Rating Inventory of Executive Functions in the evaluation of the daily life executive function in myoclonic-atonic epilepsy. Epilepsy Behav 2019; 99:106482. [PMID: 31461681 DOI: 10.1016/j.yebeh.2019.106482] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 08/02/2019] [Accepted: 08/03/2019] [Indexed: 11/24/2022]
Abstract
PURPOSE Executive functions (EF) are high-order cognitive skills that have a major influence on quality of life, social skills, and school achievement. We aimed to screen EF daily life abilities in young patients with myoclonic-atonic epilepsy (MAE) using an ecological questionnaire and to correlate EF to epilepsy characteristics. METHODS Behavioral Rating Inventory of Executive Functions - Preschool (BRIEF-P) and BRIEF - for school-aged patients - parental questionnaires were proposed to patients with MAE and typically developing children (TDC) including Inhibit, Shift, Emotional control, Working memory (WM), Plan/Organize, Initiate, Organization of materials, and Monitor subscales. We included prospectively 12 patients with MAE and 44 TDC aged 3 to 5 years and seven patients with MAE and 21 TDC aged 6-7 years. We performed in addition for all patients an intellectual efficiency evaluation using WPPSI-IV (Wechsler intelligence scale for preschool children version IV) and collected demographics, age at onset of epilepsy, epilepsy duration, response to treatment, number and type of treatments including AEDs (antiepileptic drugs), and ketogenic diet. RESULTS Four out of 12 patients for BRIEF-P and 6/7 patients for BRIEF had pathological scores for at least one domain. Behavioral Rating Inventory of Executive Functions' questionnaires showed higher pathological scores for WM, Plan/Organize, Initiate, Monitor, and Metacognition Index in patients with MAE compared to TDC suggesting higher problems reported by parents. Working memory scores were higher in the group with MAE than TDC for both BRIEF-P and BRIEF. Response to treatment is a predictor of multiple BRIEF-P domains. Epilepsy duration predicts Shift and WM domains while age at onset predicts WM domain on BRIEF in this syndrome. CONCLUSIONS This study is the first to assess prospectively EF in young patients with MAE. We show everyday deficits in EF reported by parents. Metacognition and more specifically WM, appear to be a core deficit. Early evaluation of EF using both questionnaires and standardized tools is necessary for early detection of EF deficit and initiating tailored rehabilitation. Given the normal development before seizure onset and the absence of cerebral lesion in MAE, these results are in favor of the impact of epilepsy on EF.

Abstract
Thirty-two children with frontal lobe epilepsy (FLE) were assessed using different working memory measures. In addition, parents and teachers completed the working memory scale of the Behavioral Rating Inventory of Executive Functioning (BRIEF) to assess the children's "daily life behavior." Results suggested minimal working memory deficits as assessed with performance-based measures. However, the BRIEF showed more working memory deficits suggesting that, on a daily life level, working memory problems seem to be associated with FLE. We discuss why the results of the performance-based measures are not consistent with results of the BRIEF.HighlightsParents as well as teachers report working memory dysfunction in daily life to the same extent.Performance based measures show minimal deficits of working memory.Correlation between working memory tasks and proxy measures are low.

Abstract
OBJECTIVE The objectives of this study were to identify executive functioning (EF) phenotypes in youth with epilepsy and to examine whether phenotypes differ on psychosocial and medical outcomes (i.e., absence/presence of seizures in the past three months), health-related quality of life (HRQOL), and emotional and behavioral functioning. METHODS Youth 5-18 years with diagnosed epilepsy and caregivers completed a battery of questionnaires as part of a larger national validation of the Pediatric Quality of Life (PedsQL) Epilepsy Module. The primary measure of interest was the Behavior Rating Inventory of Executive Function-Parent Form. Medical chart reviews and demographic data were also collected. Latent class analysis was used to identify EF phenotypes. Chi-square and analyses of covariance (ANCOVA) were conducted to examine EF phenotype group differences on seizure outcomes, HRQOL, and behavioral and emotional functioning. RESULTS Two-hundred and thirty-seven children with epilepsy (Mage = 11.2 years; 56% female; 60% White: Non-Hispanic; 55% experienced seizures in the past three months) and their caregivers participated. Four EF phenotypes were identified: Group 1 - No EF deficits (45% of sample), Group 2 - Global EF deficits (29% of sample), Group 3 - Behavioral Regulation + Working Memory deficits (8% of sample), and Group 4 - Metacognitive deficits (17% of sample). No significant EF phenotype group differences were found for seizure characteristics. The ANCOVAs indicated significant EF phenotype group differences on HRQOL (parent-reported Impact, Cognitive, Sleep, EF, and Mood/Behavior and child-reported Cognitive, Sleep, EF, and Mood/Behavior subscales; ps < .001) and emotional and behavioral functioning (Externalizing, Internalizing, and Behavioral Symptom Index; ps < .001), with the Global EF deficits (Group 2) and Behavioral Regulation + Working Memory deficits groups (Group 3) demonstrating the greatest level of impairment. CONCLUSION Phenotypic variability in EF is significantly related to patient-reported outcomes. Interventions addressing EF deficits need to be individualized to a child's particular EF phenotype to achieve optimal outcomes.

Abstract
Few studies have reported on the quantity and quality of executive function (EF) deficits in young children referred to child psychiatric outpatient clinic with multiple psychiatric symptoms. We evaluated the EF deficits with the Attention and Executive Function Rating Inventory-Preschool (ATTEX-P) filled out by day care teachers for 4- to 7-year-old clinical group ( n = 171) and reference group ( n = 709). Family background information was collected from all families by parent questionnaire. Diagnoses of the referred children were collected from medical records. Clinical group exhibited higher mean ranks across the ATTEX-P Total score and all nine subscales than reference group ( p < .001). Most of the children in the clinical group (58.5%) showed a significant amount of EF deficits (ATTEX-P Total score over clinical cut-off) including distractibility (55.6%) and impulsivity (53.8%) regardless of their diagnoses. In a multiple logistic regression model (controlling for age, gender and parental education), children in the clinical group had increased risk (odds ratio (OR)) = 10.6, 95% confidence interval (CI) = [6.88, 16.2], p < .001) for scoring over the clinical cut-off point on the ATTEX-P Total score. Assessment of EFs should be a routine part of the treatment plan in young children referred to child psychiatric outpatient clinic as it may guide the treatment choices.

Abstract
OBJECTIVES Neurofibromatosis type 1 (NF1) is a genetic disorder in which the most frequent complication in children is learning disabilities. Over the past decade, growing arguments support the idea that executive dysfunction is a core deficit in children with NF1. However, some data remain inconsistent. The aim of this study was to determine the magnitude of impairment for each executive function (EF) and clarify the impact of methodological choices and participant's characteristics on EFs. METHODS In this meta-analysis, 19 studies met the selection criteria and were included with data from a total of 805 children with NF1 and 667 controls. Based on the Diamond's model (2013), EF measures were coded separately according to the following EF components: working memory, inhibitory control, cognitive flexibility, planning/problem solving. The review protocol was registered with PROSPERO (International prospective register of systematic reviews; CRD42017068808). RESULTS A significant executive dysfunction in children with NF1 is demonstrated. Subgroup analysis showed that the impairment varied as a function of the specific component of executive functioning. The effect size for working memory and planning/problem solving was moderate whereas it was small for inhibitory control and cognitive flexibility. Executive dysfunction seems to be greater with increasing age whereas assessment tool type, intellectual performance, attention deficit hyperactivity disorder and control group composition did not seem to affect EF results. CONCLUSIONS EF deficits are a core feature in children with NF1 and an early identification of executive dysfunctions is essential to limit their impact on the quality of life.

Abstract
Youth with epilepsy demonstrate deficits in executive functioning (EF), the skills necessary for goal-directed behavior (e.g., problem-solving, initiating, monitoring, organization, planning, and working memory). Despite 30-50% of youth with epilepsy demonstrating EF deficits, no extant studies have utilized both performance and questionnaire-based measures to examine the pattern of EF deficits in adolescents with epilepsy. Study aims were to 1) identify the pattern of EF deficits in adolescents with epilepsy and 2) identify which assessment tools are most sensitive to EF deficits in this population (adolescents, ages 13-17, with epilepsy). An exploratory aim was to examine group differences on measures of EF by epilepsy type. Standard performance-based neuropsychological measures (Wechsler Intelligence Scale for Children - Version V or Wechsler Adult Intelligence Scale Working Memory Index-Version IV, Delis Kaplan Executive Functioning System, NIH Toolbox, Test of Everyday Attention for Children) and the Behavior Rating Inventory of Executive Functioning (BRIEF) comprised the multimethod assessment battery. Depending on the measure, 30% of adolescents with epilepsy had deficits in working memory, 17% in cognitive flexibility/problem solving, 6% in inhibition, and 18% in planning/organization. Attention was a significant problem for 15% of adolescents with epilepsy. Correlations among the various EF measures were quite poor. Across various EF domains, results indicated that adolescents with localization-related epilepsy demonstrated better EF skills compared to adolescents with unclassified epilepsy. Overall, our findings suggest that executive functioning deficits are selective and different from those observed in other neurological populations (e.g., attention deficit hyperactivity disorder (ADHD), traumatic brain injury) where problems with self-regulation (i.e., inhibition, planning/organization) are more pronounced. These findings support utilizing multiple measures, including both performance-based neuropsychological tests and parent- and self-reports, to assess executive functioning difficulties in adolescents with epilepsy as they are uniquely sensitive to executive functioning domains. Adolescents with unclassified epilepsy also appear to be at higher risk for EF deficits and thus represent an important group to target for intervention.

Abstract
Executive function (EF) difficulties are a core neuropsychological feature of pediatric epilepsy, and parent-report measures of EF concerns are an important complement to task-based EF measures. The Behavior Rating Inventory of Executive Function (BRIEF) has shown sensitivity to parent-reported EF concerns in epilepsy and other pediatric populations. We compared profiles of parent-reported EF concerns using the BRIEF and its revision, the BRIEF2, in 117 pediatric patients with focal onset epilepsy to examine the clinical utility of the revised scale. We then compared BRIEF2 profiles between patients and age- and gender-matched healthy controls. Among patients, profiles on the BRIEF did not globally differ from the BRIEF2, and agreement was very good across scales. Patients and controls differed significantly on the BRIEF2, with patients showing higher EF difficulties reported by parents across most scales. High rates of clinical elevation among patients emerged on the Task Monitor, Plan/Organize, Working Memory, and Shift scales. Younger age of epilepsy onset, chronic epilepsy, and right hemisphere seizure focus were associated with higher parent-reported EF concerns. Findings suggest that the BRIEF2 demonstrates similar performance to the BRIEF among pediatric patients with focal onset epilepsy who are most at risk in the areas of task monitoring, working memory, planning and organization, and flexibility. These findings are informative when comparing literature across versions and provide additional insight into the nature of parent-reported EF difficulties among children with focal onset epilepsy.

Safety and efficacy of glycerol phenylbutyrate for management of urea cycle disorders in patients aged 2months to 2years. Mol Genet Metab 2017; 122:46-53. [PMID: 28916119 DOI: 10.1016/j.ymgme.2017.09.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2017] [Revised: 09/01/2017] [Accepted: 09/01/2017] [Indexed: 12/30/2022]
Abstract
INTRODUCTION Glycerol phenylbutyrate (GPB) is approved in the US for the management of patients 2months of age and older with urea cycle disorders (UCDs) that cannot be managed with protein restriction and/or amino acid supplementation alone. Limited data exist on the use of nitrogen conjugation agents in very young patients. METHODS Seventeen patients (15 previously on other nitrogen scavengers) with all types of UCDs aged 2months to 2years were switched to, or started, GPB. Retrospective data up to 12months pre-switch and prospective data during initiation of therapy were used as baseline measures. The primary efficacy endpoint of the integrated analysis was the successful transition to GPB with controlled ammonia (<100μmol/L and no clinical symptoms). Secondary endpoints included glutamine and levels of other amino acids. Safety endpoints included adverse events, hyperammonemic crises (HACs), and growth and development. RESULTS 82% and 53% of patients completed 3 and 6months of therapy, respectively (mean 8.85months, range 6days-18.4months). Patients transitioned to GPB maintained excellent control of ammonia and glutamine levels. There were 36 HACs in 11 patients before GPB and 11 in 7 patients while on GPB, with a reduction from 2.98 to 0.88 episodes per year. Adverse events occurring in at least 10% of patients while on GPB were neutropenia, vomiting, diarrhea, pyrexia, hypophagia, cough, nasal congestion, rhinorrhea, rash/papule. CONCLUSION GPB was safe and effective in UCD patients aged 2months to 2years. GPB use was associated with good short- and long-term control of ammonia and glutamine levels, and the annualized frequency of hyperammonemic crises was lower during the study than before the study. There was no evidence for any previously unknown toxicity of GPB.
