Should pediatric neurologists play a role in the management of the most common psychiatric comorbidities in children with epilepsy? Practical considerations.

Child neurologists should provide initial care for the mental health problems of children and adolescents with epilepsy. Attention deficit hyperactivity disorder (ADHD), autism spectrum disorders are common comorbidities of childhood epilepsy. The psychotropic drugs used to treat mental health disorders can be safely employed in children with seizures. Child neurologists can diagnose common behavioral problems, should be comfortable with first-line agents to treat common psychiatric illnesses, and should recognize when support from psychologists or child and adolescent psychiatrists is needed. This article is part of the Special Issue "Obstacles of Treatment of Psychiatric Comorbidities in Epilepsy".

Continuous local anaesthetic wound infusion for postoperative pain after midline laparotomy for colorectal resection in adults.

BACKGROUND: Colorectal resection through a midline laparotomy is a commonly performed surgical procedure to treat various bowel conditions. The typical postoperative hospital stay after this operation is 6 to 10 days. The main factors hindering early recovery and discharge are thought to include postoperative pain and delayed return of bowel function.Continuous infusion of a local anaesthetic into tissues surrounding the surgical incision via a multi-lumen indwelling wound catheter placed by the surgeon prior to wound closure may reduce postoperative pain, opioid consumption, the time to return of bowel function, and the length of hospital stay. OBJECTIVES: To evaluate the efficacy and adverse events of continuous local anaesthetic wound infusion for postoperative pain after midline laparotomy for colorectal resection in adults. SEARCH METHODS: We searched the CENTRAL, MEDLINE and Embase databases to January 2019 to identify trials relevant to this review. We also searched reference lists of relevant trials and reviews for eligible trials. Additionally, we searched two clinical trials registers for ongoing trials. SELECTION CRITERIA: We considered randomised controlled trials (including non-standard designs) or quasi-randomised controlled trials comparing continuous wound infusion of a local anaesthetic versus a placebo or a sham after midline laparotomy for colorectal resection in adults. We did not compare continuous local anaesthetic wound infusion to other techniques, such as transverse abdominis plane block or thoracic epidural analgesia. We allowed non-randomised analgesic co-interventions carried out equally in the intervention and control groups. DATA COLLECTION AND ANALYSIS: Two review authors independently identified trials for inclusion and assessed their quality using the Cochrane 'Risk of bias' tool. We extracted data using standardised forms, including pain at rest and on movement (10-point scale), opioid consumption via a patient-controlled analgesia (PCA) system (mg morphine equivalent), postoperative opioid-related adverse events, the time to rescue analgesia, the time to first flatus and to first bowel movement, the time to ambulation, the length of hospital stay, serious postoperative adverse events, and patient satisfaction. We quantitatively synthesised the data by meta-analysis. We summarised and graded the certainty of the evidence for critical outcomes using the GRADEpro tool and created a 'Summary of findings' table. MAIN RESULTS: This review included six randomised controlled trials that enrolled a total of 564 adults undergoing elective midline laparotomy for colorectal resection comparing continuous wound infusion of a local anaesthetic to a normal saline placebo. Due to 23 post-randomisation exclusions, a total of 541 participants contributed data to the analysis of at least one outcome (local anaesthetic 268; control 273). Most participants were aged 55 to 65 years, with normal body mass index and low to moderate anaesthetic risk (American Society of Anesthesiologists class I-III). Random sequence generation, allocation concealment, and blinding were appropriately carried out in most trials. However, we had to downgrade the certainty of the evidence for most outcomes due to serious study limitations (risk of bias), inconsistency, indirectness, imprecision and reporting bias.Primary outcomesOn postoperative day 1, pain at rest (mean difference (MD) -0.59 (from 3.1), 95% confidence interval (CI) -1.12 to -0.07; 5 studies, 511 participants; high-certainty evidence), pain on movement (MD -1.1 (from 6.1), 95% CI -2.3 to -0.01; 3 studies, 407 participants; low-certainty evidence) and opioid consumption via PCA (MD -12 mg (from 41 mg), 95% CI -20 to -4; 6 studies, 528 participants; moderate-certainty evidence) were reduced in the local anaesthetic group compared to the control group.Secondary outcomesThere was a reduction in the time to first bowel movement (MD -0.67 from 4.4 days, 95% CI -1.17 to -0.17; 4 studies, 197 participants; moderate-certainty evidence) and the length of hospital stay (MD -1.2 from 7.4 days, 95% CI -2.0 to -0.3; 4 studies, 456 participants; high-certainty evidence) in the local anaesthetic group compared to the control group.There was no evidence of a difference in any serious postoperative adverse events until hospital discharge (RR 1.04, 95% CI 0.68 to 1.58; 6 studies, 541 participants; low-certainty evidence) between the two study groups. AUTHORS' CONCLUSIONS: After elective midline laparotomy for colorectal resection, continuous wound infusion of a local anaesthetic compared to a normal saline placebo reduces postoperative pain at rest and the length of hospital stay, on the basis of high-certainty evidence. This means we are very confident that the effect estimates for these outcomes lie close to the true effects. There is moderate-certainty evidence to indicate that the intervention probably reduces opioid consumption via PCA and the time to first bowel movement. This means we are moderately confident that effect estimates for these outcomes are likely to be close to the true effects, but there is a possibility that they are substantially different. The intervention may reduce postoperative pain on movement, however, this conclusion is based on low-certainty evidence. This means our confidence in the effect estimate is limited. The true effect may be substantially different from the estimate of the effect. There is low-certainty evidence to indicate that the intervention may have little or no effect on the rates of any serious postoperative adverse events until hospital discharge. High-quality randomised controlled trials to evaluate the intervention with a focus on important clinical and patient-centred outcomes are needed.

Children with new onset seizures: A prospective study of parent variables, child behavior problems, and seizure occurrence.

OBJECTIVE: Parent variables (stigma, mood, unmet needs for information and support, and worry) are associated with behavioral difficulties in children with seizures; however, it is not known how this relationship is influenced by additional seizures. This study followed children (ages 4-14 years) and their parents over a 24-month period (with data collected at baseline and 6, 12, and 24 months) and investigated the effect of an additional seizure on the relationship between parenting variables and child behavior difficulties. METHODS: The sample was parents of 196 children (104 girls and 92 boys) with a first seizure within the past 6 weeks. Child mean age at baseline was 8 years, 3 months (SD 3 years). Data were analyzed using t-tests, chi-square tests, and repeated measures analyses of covariance. RESULTS: Relationships between parent variables, additional seizures, and child behavior problems were consistent across time. Several associations between parent variables and child behavior problems were stronger in the additional seizure group than in the no additional seizure group. CONCLUSIONS: Findings suggest that interventions that assist families to respond constructively to the reactions of others regarding their child's seizure condition and to address their needs for information and support could help families of children with continuing seizures to have an improved quality of life.

A model for internalized stigma in children and adolescents with epilepsy.

OBJECTIVE: Perceptions of stigma in children and adolescents with epilepsy are associated with higher rates of mental health problems. The purpose of this study was to test relationships in a model that identified variables most strongly associated with perceptions of stigma in children and adolescents with epilepsy. Our ultimate goal is to develop a theoretical foundation for future intervention research by identifying variables associated with perceptions of stigma that are potentially amenable to psychosocial interventions. METHODS: Participants were 173 children and adolescents with epilepsy who were between 9 and 14 years of age. Data were collected in telephone interviews. Stigma was measured using a self-report scale. Data were analyzed using structural equation modeling. RESULTS: Greater need for information and support, more fear and worry related to having epilepsy, greater seizure severity, and younger age were significantly associated with greater perceptions of stigma. Female gender, greater need for information and support, having at least one seizure in the past year, and lower self-efficacy for seizure management were significantly associated with more fear and worry related to having epilepsy. CONCLUSIONS: Findings suggest that perceptions of stigma are associated with two variables that are amenable to psychosocial interventions: fear and worry about having epilepsy and need for information and support. Future research should test the efficacy of interventions that reduce fear and worry, provide information about epilepsy, and reduce need for support.

Language and social functioning in children and adolescents with epilepsy.

Individuals with epilepsy have difficulties with social function that are not adequately accounted for by seizure severity or frequency. This study examined the relationship between language ability and social functioning in 193 children with epilepsy over a period of 36months following their first recognized seizure. The findings show that children with persistent seizures have poorer language function, even at the onset of their seizures, than do their healthy siblings, children with no recurrent seizures, and children with recurrent but not persistent seizures. They continue to demonstrate poorer language function 36months later. This poor language function is associated with declining social competence. Intervention aimed at improving social competence should include consideration of potential language deficits that accompany epilepsy and social difficulty.

Comorbidity of attention deficit hyperactivity disorder in a patient with epilepsy: Staring down the challenge of inattention versus nonconvulsive seizures.

Epilepsy is a heterogeneous disorder of recurrent seizures which often is comorbid with anxiety, depression, attention deficit hyperactivity disorder (ADHD), intellectual disability (ID), and other psychiatric manifestations. Treating both epilepsy and behavioral symptoms from psychiatric disorders can result in polypharmacy with interactions of medications leading to both worsened efficacy of antiseizure medications due to psychotropic effects and worsening of psychiatric symptoms due to antiseizure medication side effects. We aim to suggest pragmatic strategies for the neurologist in the diagnosis and management of comorbid ADHD in patients with epilepsy based on the International League Against Epilepsy (ILAE) Pediatric Commission guidelines and additional literature review. The screening tool of choice for the symptoms of ADHD is validated in the country of practice and written in the language of the family, though various screening tools and advantages and disadvantages of each will be discussed. Once ADHD is diagnosed, recent safety data suggest that Methylphenidate, Amphetamine, and Atomoxetine are generally safe for patients with epilepsy. We present a case of a child with epilepsy and ADHD and discuss the clinical signs, symptoms, and strategies for treatment as well as when to refer to child psychiatry.

Functional MRI and structural MRI as tools for understanding comorbid conditions in children with epilepsy.

Children with epilepsy are at risk for behavioral and cognitive comorbidities. Potential etiologies can be assessed in part by neuroimaging. Functional magnetic resonance imaging (MRI) has a major role in presurgical evaluation and prediction of postoperative outcome by mapping of language and memory. Structural MRI and functional MRI have shown changes in children and adolescents with attention deficit hyperactivity disorder and disruptive behavior, common comorbidities in children with epilepsy. Neuroimaging has the potential for significantly increasing understanding of the basis of cognitive and behavioral problems in children with epilepsy.

Creating Avenues for Parent Partnership (CAPP): an intervention for parents of children with epilepsy and learning problems.

Caregivers of children with both epilepsy and learning problems need assistance to manage their child's complex medical and mental health problems. We tested the cognitive behavioral intervention "Creating Avenues for Parent Partnership" (CAPP) which was designed to help caregivers develop knowledge as well as the confidence and skills to manage their child's condition. The CAPP intervention consisted of a one-day cognitive behavioral program and three follow-up group sessions. The sample comprised 31 primary caregivers. Caregivers reported that the program was useful (mean = 3.66 on a 4-point scale), acceptable (mean = 4.28 on a 5-point scale), and "pretty easy" (mean = 1.97 on a 4-point scale). Effect sizes were small to medium in paired t tests (comparison of intervention to control) and paired analysis of key variables in the pre- and post-tests. The CAPP program shows promise in helping caregivers build skills to manage their child's condition.

White matter abnormalities associated with disruptive behavior disorder in adolescents with and without attention-deficit/hyperactivity disorder.

Disruptive behavior disorders (DBD) are among the most commonly diagnosed mental disorders in children and adolescents. Some important characteristics of DBD vary based on the presence or absence of comorbid attention-deficit/hyperactivity disorder (ADHD), which may affect the understanding of and treatment decision-making related to the disorders. Thus, identifying neurobiological characteristics of DBD with comorbid ADHD (DBD+ADHD) can provide a basis to establish a better understanding of the condition. This study aimed to assess abnormal white matter microstructural alterations in DBD+ADHD as compared to DBD alone and healthy controls using diffusion tensor imaging (DTI). Thirty-three DBD (19 with comorbid ADHD) and 46 age-matched healthy adolescents were studied using DTI. Fractional anisotropy (FA), and mean diffusivity (MD), radial diffusivity (RD) and axial diffusivity (AD) were analyzed using tract-based spatial statistics (TBSS). Significantly lower FA and higher MD, RD and AD in many white matter fibers were found in adolescents with DBD+ADHD compared to controls. Moreover, lower FA and higher RD were also found in the DBD+ADHD versus the DBD alone group. Alterations of white matter integrity found in DBD patients were primarily associated with ADHD, suggesting that ADHD comorbidity in DBD is reflected in greater abnormality of microstructural connections.

Psychosocial issues for children with epilepsy.

Epilepsy is a pervasive disorder that consists not only of seizures, but of behavioral, academic, and social difficulties. Epilepsy has an impact on the entire family and may have a significant effect on the interrelationships between child and parent. Epilepsy also has a potentially deleterious effect on academic functioning that may be the result of central nervous system dysfunction, seizures, antiepileptic drugs, or child and family response to illness. Early assessment for psychosocial problems and appropriate interventions can be beneficial for the child and family. Particular attention should be paid to periods of transition such as the move from adolescence to adulthood.

The interacting role of media violence exposure and aggressive-disruptive behavior in adolescent brain activation during an emotional Stroop task.

Only recently have investigations of the relationship between media violence exposure (MVE) and aggressive behavior focused on brain functioning. In this study, we examined the relationship between brain activation and history of media violence exposure in adolescents, using functional magnetic resonance imaging (fMRI). Samples of adolescents with no psychiatric diagnosis or with disruptive behavior disorder (DBD) with aggression were compared to investigate whether the association of MVE history and brain activation is moderated by aggressive behavior/personality. Twenty-two adolescents with a history of aggressive behavior and diagnosis of either conduct disorder or oppositional-defiant disorder (DBD sample) and 22 controls completed an emotional Stroop task during fMRI. Primary imaging results indicated that controls with a history of low MVE demonstrated greater activity in the right inferior frontal gyrus and rostral anterior cingulate during the violent word condition. In contrast, in adolescents with DBD, those with high MVE exhibited decreased activation in the right amygdala, compared with those with low MVE. These findings are consistent with research demonstrating the importance of fronto-limbic structures for processing emotional stimuli, and with research suggesting that media violence may affect individuals in different ways depending on the presence of aggressive traits.

Self-esteem and symptoms of depression in children with seizures: relationships with neuropsychological functioning and family variables over time.

PURPOSE: To test over time the relationships of neuropsychological functioning to mental health in children following a first recognized seizure and, of primary importance, to determine if the strength of these relationships differs based on risk and protective factors. METHODS: In a larger prospective study, 135 children with a first seizure (ages 8-14 years) and 73 healthy sibling controls completed neuropsychological testing at baseline and 36 months. Structured telephone interviews were used to obtain data from children on mental health and family environment; major caregiving parents provided data on demographic and family variables. Data analyses included correlation coefficients and linear regression models. RESULTS: Children with seizures showed an overall trend for improvement in mental health. More children with seizures than siblings had declines in processing speed. Declines in neuropsychological functioning were correlated with worse mental health. With regard to risk and protective factors, higher parent education protected against decline in self-esteem related to decline in processing speed. Better family functioning and greater parental support protected against decline in self-esteem related to decrease in verbal memory and learning. Older child age protected against increase in depressive symptoms related to decline in processing speed. DISCUSSION: Seizure onset had a negative impact on mental health in children with declines in cognitive functioning except for older children and those with more family resources. Children should be assessed for declines in processing speed and, if found, those subgroups of children with less educated or more anxious parents and those in less supportive families should be targeted for interventions.

Academic problems in children with seizures: relationships with neuropsychological functioning and family variables during the 3 years after onset.

OBJECTIVES: Children with long-standing epilepsy have a significantly increased risk of academic underachievement compared with healthy controls. We prospectively followed children from seizure onset to assess the relationship between change in neuropsychological functioning and change in academic achievement and to explore the risk and protective moderating effects of demographic, seizure, and family variables. METHODS: As part of a larger study, neuropsychological and academic data were collected at both baseline and 36 months for 219 children 6-14 years of age with seizures. Prior factor analysis of results from a battery of well-standardized neuropsychological tests yielded four factors: language, processing speed, attention/executive/construction, and verbal memory/learning. Academic achievement was measured with the Woodcock-Johnson Revised Achievement Test Battery. Correlation coefficients and linear mixed models were used for analysis. RESULTS: The reading and math scores of children with seizures and siblings did not differ at baseline, but children with seizures had lower scores than siblings at 36 months. Writing scores were significantly lower for affected children than siblings at both times. Among children with seizures, there were positive correlations between neuropsychological functioning and academic achievement at baseline and 36 months. Changes in language and in verbal memory/learning were positively correlated with change in reading achievement (r = 0.25 and r = 0.17, respectively). Age at onset moderated the association between change in neuropsychological functioning and change in reading and writing achievement (P ≤ 0.006), with stronger relationships among younger children (ß = 0.25-0.44). The association between change in language and change in writing achievement was moderated by caregiver anxiety (P = 0.04; stronger for more anxious parents, ß = 0.40), and the association between change in processing speed and change in math achievement was moderated by etiology (P = 0.02; stronger for symptomatic/cryptogenic vs idiopathic, ß = 0.29). Gender and other family variables did not have significant moderating effects. CONCLUSIONS: Changes in neuropsychological function were associated with changes in academic achievement following onset of seizures, with risk factors being younger age at onset, lower caregiver education, high parental anxiety, and symptomatic/cryptogenic etiology. Academic performance should be closely monitored in children with early-onset seizures.

Pediatric psychogenic nonepileptic seizures: a study of assessment tools.

The goal of this study was to identify assessment tools and associated behavioral domains that differentiate children with psychogenic nonepileptic seizures (PNES) from those with epilepsy. A sample of 24 children with PNES (mean age 14.0 years, 14 female), 24 children with epilepsy (mean age 13.6 years, 13 female), and their parents were recruited from five epilepsy centers in the United States. Participants completed a battery of behavioral questionnaires including somatization, anxiety, and functional disability symptoms. Children with PNES had significantly higher scores on the Childhood Somatization and Functional Disability Inventories, and their parents reported more somatic problems on the Child Behavior Checklist (CBCL). Depression, anxiety, and alexithymia instruments did not differentiate the groups. Measures of somatization and functional disability may be promising tools for differentiating the behavioral profile of PNES from that of epilepsy. Increased somatic awareness and perceived disability emphasize the similarity of PNES to other pediatric somatoform disorders.

The effect of temperament and neuropsychological functioning on behavior problems in children with new-onset seizures.

The present study is part of a larger project that seeks to identify factors that predict children's behavioral, social, and cognitive adaptation to epilepsy. Children with seizures are more likely to have internalizing and externalizing behavior problems than either healthy children or children with other chronic illnesses. The present research examines risk factors for behavior problems. Early temperament and neuropsychological functioning, specifically executive function and language abilities, are evaluated as unique and moderating predictors of adverse behavioral outcomes in 229 children with a first recognized seizure. Parents assessed temperament, children were administered neuropsychological tests, and teachers evaluated behavior 36 months after seizure onset. Results revealed that early temperament and neuropsychological functioning, specifically executive function, predicted behavioral outcomes 3 years after seizure onset.

Prevalence of psychopathology in childhood epilepsy: categorical and dimensional measures.

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 Checklist (CBCL), and a categorical measure, either the Child Symptom Inventory (CSI) or the Adolescent Symptom Inventory (ASI). Correlation coefficients were computed between the CBCL scores and CSI/ASI symptom scores. For all children, diagnostic risk was higher than norms on CSI/ASI for attention-deficit-hyperactivity disorder (ADHD) inattentive type, ADHD combined type, oppositional defiant disorder, and dysthymic disorder. For children between 9 and 12 years, elevated scores were found on CBCL, total, internalizing, and attention problems, and on CSI, diagnostic risk for conduct disorder and Asperger syndrome. For children of 13 and 14 years, ASI diagnostic risk was higher for specific phobia, obsessions, posttraumatic stress disorder, motor tics, antisocial personality, panic attack, somatization disorder, and enuresis. CBCL and symptom scores on the CSI/ASI were significantly correlated. The conclusion was that children with epilepsy have high rates of behavioral difficulties on both dimensional and categorical measures. Concurrent validity for the CSI/ASI was supported.

Seizure recurrence risk following a first seizure in neurologically normal children.

PURPOSE: To define seizure recurrence rates in normal children who had had a single seizure and to define electroencephalography (EEG) or magnetic resonance imaging (MRI) utility in predicting seizure recurrence. METHODS: We studied 150 children (6 to 14 years) with a first afebrile, unprovoked seizure. Inclusion criteria were: Normal physical and neurological examination, undergone EEG and MRI studies of the brain, and followed for at least 27 months. These children participated in an ongoing prospective study of new onset seizures in childhood. RESULTS: The seizure recurrence rate was 66.4%. An abnormal EEG had no association with seizure recurrence at 9, 18, or 27 months (p = 0.1806, p = 0.2792, and p = 0.2379, respectively). A "significant" MRI abnormality, which occurred in 16.0% of patients, was associated with an increased seizure recurrence risk at 9 months (p = 0.0389) but not at 18 or 27 months. DISCUSSION: EEG findings poorly predict recurrence after a single seizure. The high rate of MRI abnormalities suggests that MRI may need consideration as a routine test to evaluate epilepsy in normal children.
