Social competence in pediatric epilepsy: insights into underlying mechanisms

The diagnosis of ADHD in children and adolescents with epilepsy: a scoping review

Attention-deficit hyperactivity disorder (ADHD) is often diagnosed in children and adolescents with epilepsy, but clear clinical guidelines on how to make this diagnosis are still lacking. Without these guidelines, there is no consensus between specialists on how to proceed when assessing children with epilepsy for ADHD, which can negatively impact the quality of care being offered to this population. As a first step toward gaining more specific clinical guidelines, this scoping review was aimed at documenting the tools and procedures used to diagnose ADHD in children and adolescents with epilepsy over time and at determining whether the diagnoses were made in accordance with clinical guidelines and recommendations. The literature search was conducted using PsycINFO, PubMed, and CINAHL. Studies were included if conducted with children and adolescents aged between 4 and 18 years with epilepsy being evaluated for ADHD. Studies were clustered according to their publication date and the reported diagnostic procedures were identified. Forty-nine out of 3854 records were included. Results highlight discrepancies between how ADHD was diagnosed in reviewed studies and clinical guidelines or recommendations. Indeed, most studies did not use a multi-method and multi-informant approach when diagnosing ADHD in children with epilepsy, with no improvement over time. Future studies aimed at diagnosing ADHD in children and adolescents should ensure that they are following clinical guidelines and recommendations, in addition to adapting their diagnostic procedures to the presence of any neurological comorbidities, such as epilepsy.

Social impairment in children with epilepsy assessed by the social responsiveness scale

Children with epilepsy are at risk for impaired social cognition and autism. We aimed at evaluating the utility of the social responsiveness scale (SRS) for assessment of social impairment in these children. Prospective study; the SRS was applied to a group of children with epilepsy and a healthy control group. Intellectual disability in the epilepsy group was assessed utilizing adapted versions of the Wechsler Intelligence and adaptive behavior scales. One hundred and one children with epilepsy and 92 healthy children were included. The majority of children in both groups had normal SRS scores. Significant differences were identified in children with high total scores indicating significant deficiencies in reciprocal social behavior; high scores were found in 16% of children with epilepsy versus 7% of normal children, p < .05, particularly involving social communication, p < .05. Intellectual disability was identified in 42% of children with epilepsy, particularly processing speed index, p < .001. Intellectual disability had a significant effect on total scores, p = .016. Children with epilepsy have increased risk of social impairments. Social impairments are more likely in the presence of intellectual disability. The SRS is a quick identification tool that can be employed in the outpatient setting.

Language measurement in childhood epilepsy: A review

The psychosocial well-being of children and adolescents with epilepsy is affected by comorbid language deficits. Little is known about the focus of current research in language and epilepsy. A systematic review of research was conducted to identify gaps in knowledge regarding language and epilepsy. In total, 83 published articles were eligible for inclusion. More studies included samples presenting with focal seizures (k = 39) compared to generalized seizures (k = 10), few included measures of morphology (k = 4). Most studies (k = 66) included samples of participants across a wide age range. Our review indicated t-hat future research should include a greater focus on participants with more diversity in epilepsy etiology (e.g., symptomatic epilepsy), and seizure type (e.g., generalized seizures), assessment of additional areas of language (e.g., morphology), increased focus on early childhood, focused examination of specific developmental stages, and greater use of comparison groups with an alternate epilepsy diagnosis.

Brief video enhances teacher trainees' knowledge of epilepsy

OBJECTIVE

Relative to the general population, children with epilepsy (CWE) demonstrate difficulties in aspects of cognition and mental health. Previous studies have found that teachers have poor knowledge about epilepsy, which may lead to inadequate management of CWE's comorbidities and seizures, potentially impacting CWE's school performance, social development, and safety. The current study aimed to evaluate whether a brief training program improves teachers' epilepsy knowledge.

METHOD

Participants included pre-service teachers enrolled in the Faculty of Education at Western University (London, Ontario, Canada). There were no exclusion criteria. Pre-service teachers completed a questionnaire evaluating their experiences and knowledge of epilepsy prior to, and two weeks following, the training program. The training program consisted of a 10.5-min video and booklet that described the characteristics of seizures, seizure first aid, and the cognitive, psychological, and social consequences of epilepsy.

RESULTS

Pre-service teachers' knowledge about epilepsy, seizure safety, and common comorbidities associated with epilepsy significantly improved after participating in the training program. Furthermore, pre-service teachers indicated greater self-reported knowledge about epilepsy and greater preparedness to handle a seizure in the classroom.

CONCLUSION

The results of the current study demonstrated that a brief, cost-effective training program significantly enhances teachers' knowledge about epilepsy, seizure safety, and the comorbidities associated with epilepsy. Enhancing teachers' knowledge about epilepsy has the potential to improve children's academic and social success in school.

The impact of severe pediatric epilepsy on experienced stress and psychopathology in parents

OBJECTIVES

To assess the prevalence of psychopathology and the level of stress in parents of children with severe epilepsy to gain a better understanding of parental support needs.

METHODS

Questionnaires were completed by parents of children with severe epilepsy during the hospitalization of their child at the Danish Epilepsy Center. The questions targeted symptoms of post-traumatic stress disorder (PTSD), complex PTSD (CPTSD), depression, and anxiety, and the level of perceived stress.

RESULTS

A total of 162 caregivers of 140 children with epilepsy participated in the survey. Mothers were more often unemployed than fathers (38% vs. 11%, p < 0.01), and nearly half of the children (47%) attended special needs classes. Psychopathology symptoms were found in 43.5% of parents, fulfilling criteria for one or more diagnoses, and an additional 11% showed symptoms of sub-clinical PTSD. Parent-rated child difficulties were significantly associated with PTSD (M_diff = 5.51, p = 0.001), depression (M_diff = 4.50, p < 0.000), and anxiety (M_diff = 4.61, p = 0.01), and with higher levels of perceived stress (p < 0.001).

CONCLUSION

Caring for a child with severe epilepsy has a significant psychopathological impact on caregivers. Caregivers' resources and the degree of behavioral difficulties in the child, rather than epilepsy-related factors, are highly correlated with distress and psychopathological symptoms in caregivers.

Warped rhythms: Epileptic activity during critical periods disrupts the development of neural networks for human communication

It is well established that temporal lobe epilepsy-the most common and well-studied form of epilepsy-can impair communication by disrupting social-emotional and language functions. In pediatric epilepsy, where seizures co-occur with the development of critical brain networks, age of onset matters: The earlier in life seizures begin, the worse the disruption in network establishment, resulting in academic hardship and social isolation. Yet, little is known about the processes by which epileptic activity disrupts developing human brain networks. Here we take a synthetic perspective-reviewing a range of research spanning studies on molecular and oscillatory processes to those on the development of large-scale functional networks-in support of a novel model of how such networks can be disrupted by epilepsy. We seek to bridge the gap between research on molecular processes, on the development of human brain circuitry, and on clinical outcomes to propose a model of how epileptic activity disrupts brain development.

Neuroinflammation in Post-Traumatic Epilepsy: Pathophysiology and Tractable Therapeutic Targets

Epilepsy is a common chronic consequence of traumatic brain injury (TBI), contributing to increased morbidity and mortality for survivors. As post-traumatic epilepsy (PTE) is drug-resistant in at least one-third of patients, there is a clear need for novel therapeutic strategies to prevent epilepsy from developing after TBI, or to mitigate its severity. It has long been recognized that seizure activity is associated with a local immune response, characterized by the activation of microglia and astrocytes and the release of a plethora of pro-inflammatory cytokines and chemokines. More recently, increasing evidence also supports a causal role for neuroinflammation in seizure induction and propagation, acting both directly and indirectly on neurons to promote regional hyperexcitability. In this narrative review, we focus on key aspects of the neuroinflammatory response that have been implicated in epilepsy, with a particular focus on PTE. The contributions of glial cells, blood-derived leukocytes, and the blood–brain barrier will be explored, as well as pro- and anti-inflammatory mediators. While the neuroinflammatory response to TBI appears to be largely pro-epileptogenic, further research is needed to clearly demonstrate causal relationships. This research has the potential to unveil new drug targets for PTE, and identify immune-based biomarkers for improved epilepsy prediction.

Social cognition and psychopathology in childhood and adolescence

There is a substantial body of research on social cognition in adults with epilepsy, and in broad categories such as focal and generalized epilepsies, but much less has been written about social cognition in children with epilepsy (CWE), and in childhood-onset epilepsy syndromes specifically. In several of these syndromes, autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD), two disorders with social cognitive impairments, are reported. There is strong evidence for social cognitive deficits in juvenile myoclonic epilepsy (JME). There is also a considerable amount of evidence for such deficits in a number of syndromes that may be associated with ASD or ADHD, including West syndrome (WS), Dravet syndrome (DS), and the Landau-Kleffner syndrome (LKS). However, the evidence is of variable quality and incomplete across the range of childhood epilepsy syndromes. In some syndromes, childhood epilepsy substantially increases the risk of severe social cognitive impairment, which may persist after the seizures remit. This paper presents an overview of current research on social cognition in childhood epilepsy, with a particular focus on syndromes with a high prevalence of autistic and behavioral comorbidities. Social cognitive impairments represent a considerable additional challenge for patients and caregivers. Early diagnosis and intervention might significantly improve long-term social cognitive outcomes, highlighting the need for greater awareness among clinicians of this important topic. This article is part of the Special Issue "Epilepsy and social cognition across the lifespan".

Facial emotion perception and social competence in children (8 to 16 years old) with genetic generalized epilepsy and temporal lobe epilepsy

Facial emotion perception (FEP) impairments are common in adults with epilepsy and associated with impaired psychosocial functioning. Research into the presence of FEP deficits in children with epilepsy and the functional implications of these deficits is limited. The primary aims of this study were to assess FEP abilities in children (8 to 16 years old) with genetic generalized epilepsy (GGE) and temporal lobe epilepsy (TLE) and examine whether FEP is related to everyday social functioning. Forty-four children (8 to 16 years) with epilepsy (22 GGE, 22 TLE) and 22 typically developing controls completed the Pictures of Facial Affect (POFA) battery to assess FEP and a brief test of intellectual functioning (intelligence quotient [IQ]). Parents completed questionnaires assessing social competence of their child. Neurologists completed the Global Assessment of Severity of Epilepsy (GASE) scale as a measure of overall epilepsy severity. Demographic and clinical information was obtained from medical records and clinical interviews with parents. Findings revealed significant, overall FEP impairments and reduced social competence in children with GGE and TLE compared to controls. The magnitude of FEP impairment (i.e., across all emotions) was comparable in the two epilepsy groups, yet different emotions were impaired in each group: children with GGE were impaired in recognizing anger and disgust, whereas children with TLE were impaired in sadness and disgust, compared to controls. Contrary to expectations, total FEP accuracy was not significantly correlated with social competence in either epilepsy group. In conclusion, children with GGE and TLE have significant impairments recognizing emotional expressions on faces. Further research is needed to examine whether underlying FEP impairments relate to social and emotional functioning in children with epilepsy.

Clinical Significance of Incidental Rolandic Spikes in Children With Absence Epilepsy

PURPOSE

Absence epilepsy and benign epilepsy of childhood with central temporal spikes are common childhood epilepsy syndromes. Although 3-Hz generalized spike-wave discharges are almost always associated with absence seizures, rolandic spikes can be present in individuals without rolandic seizures. The co-occurrence of 3-Hz generalized spike-wave and rolandic spikes is very rare. Our objective was to compare clinical features of patients with absence epilepsy with and without rolandic spikes, to determine if the additional feature of rolandic spikes has any clinical significance.

METHODS

Clinical information of 17 children with absence epilepsy and rolandic spikes was compared to an age-matched control group of 90 children with absence epilepsy.

RESULTS

Although most patients had excellent seizure control at follow-up, epilepsy comorbidities (cognitive and emotional problems) were observed. Comparing study vs control groups, there was no difference with anxiety (2 [11.8%] vs 8 [9%]), behavioral issues (4 [23.5%] vs 10 [11%]), mood disorders (0 vs 2 [2%]), and attention-deficit hyperactivity disorder (4 [24%] vs 10 [11%]). Significant differences were also observed: more global-developmental (5 [29%] vs 5 [6%], P < .009) and expressive-language (4 [24%] vs 5 [6%], P < .034) delay and more difficulties with school performance (11 [65%] vs 32 [36%], P < .025), especially with language-related tasks (6 [35%] vs 5 [6%], P < .001).

CONCLUSION

Our results confirm the presence of additional epilepsy comorbidities in patients with absence epilepsy when rolandic spikes are present. Rolandic spikes in patients with absence epilepsy may be a marker of additional cognitive challenges that physicians should be aware of.

An investigation of the association between seizures, autism symptomology, and developmental functioning in young children

OBJECTIVE

The aim of the present study was to explore whether a history of seizures was associated with autism symptom severity and developmental functioning in young children.

METHODS

Autism symptom severity and developmental functioning were compared between children with and without a history or seizures who either had atypical development or met criteria for autism spectrum disorder (ASD) based on review of records by a licensed clinical psychologist.

RESULTS

Parents of children who met criteria for ASD reported lower levels of autism symptomology when the child had a history of seizures, while the opposite trend was found for children with atypical development. Participants without ASD or seizures had greater developmental functioning than the other groups.

CONCLUSION

The present study emphasizes the need for early identification and diagnosis of both ASD and seizure disorders, as timely intervention for these two conditions may be related to improved outcomes for young children.

Impaired theory of mind in Chinese children and adolescents with idiopathic generalized epilepsy: Association with behavioral manifestations of executive dysfunction

BACKGROUND

Epilepsy is a common neurological disorder with a core feature of cognitive impairments. Previous studies showed that patients with focal epilepsy have deficits in both theory of mind (ToM) and executive function (EF). However, there are few studies of ToM in patients with idiopathic generalized epilepsy (IGE), especially in populations with pediatric epilepsy. The aim of this study was to examine the characteristics of ToM and EF, including some of their subcomponents, and explore the relationship between them in Chinese children with IGE.

MATERIALS AND METHODS

We recruited 54 children and adolescents with IGE as the experimental subjects and 37 typically developing children and adolescents as control subjects. Both groups completed ToM tests, namely, second-order false belief tasks (FBTs) and faux pas tasks (FPTs). Their caregivers completed the Behavior Rating Inventory of Executive Function (BRIEF) at the same time.

RESULTS

Children and adolescents with IGE displayed worse performance on some of the FBTs and FPTs than healthy controls (p<0.01). They also exhibited widespread EF deficits, comprising eight subcomponents (p<0.05). Pearson's correlation analysis revealed that several subcomponents of EF (inhibition, emotional control, initiation, working memory, and monitoring) were unequally correlated with FBT and FPT. Regression analysis showed that ToM had associations with inhibition, working memory, and duration of seizures. Analysis of variance (ANOVA) indicated that children with newly diagnosed epilepsy displayed significant deficits in FBT, FPT, and distinct subscales of EF.

CONCLUSIONS

Our results revealed significant impairments in ToM and EF in children and adolescents with IGE compared with healthy controls. We found significant correlations between ToM and two subcomponents of EF (inhibition and working memory) in children with IGE. Additionally, the duration of seizures affected ToM in patients but was a less powerful predictor than the two subcomponents of EF. Even for children with new-onset seizures and without medication, the deficits in ToM and some distinct subscales of EF were apparent. This result has clinical implications for both nonpharmaceutical therapies and cognitive rehabilitation.

Medical and Psychiatric Comorbidities in Korean Children and Adolescents with Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

Attention-deficit/hyperactivity disorder (ADHD) is associated with a high rate of comorbid disorders. We aimed to investigate the medical and psychiatric comorbidities of Korean children and adolescents with ADHD.

METHODS

Data were obtained from Korean National Health Insurance Review and Assessment Service-National Patient Sample (HI-RA-NPS) for 2011. We included 2,140 (mean age, 10.9±3.1 years; boys, 1,710) and 219,410 (non-ADHD; mean age, 12.4±3.7 years; boys, 113,704) children and adolescents with and without ADHD, respectively. We compared medical and psychiatric comorbidities between the groups, and performed weighted logistic regression analyses to obtain odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

Most medical comorbidities were more likely in patients with ADHD and included nervous system disease (OR, 2.59; 95% CI, 2.52-2.66); endocrine, nutritional, and metabolic disease (OR, 2.09; 95% CI, 2.04-2.15); and congenital malformations, deformations, and chromosomal abnormalities (OR, 2.00; 95% CI, 1.90-2.11). Oppositional defiant disorder and conduct disorder were more prevalent in patients with ADHD (OR, 81.88; 95% CI, 79.00-84.86), followed by learning (OR, 75.61; 95% CI, 69.69-82.04), and depressive disorders (OR, 55.76; 95% CI, 54.44-57.11).

CONCLUSION

Our results suggest that Korean children and adolescents with ADHD are more likely to suffer medical and psychiatric comorbidities than those without ADHD.

Pretreatment behavior and subsequent medication effects in childhood absence epilepsy

OBJECTIVE

To characterize pretreatment behavioral problems and differential effects of initial therapy in children with childhood absence epilepsy (CAE).

METHODS

The Child Behavior Checklist (CBCL) was administered at baseline, week 16-20, and month 12 visits of a randomized double-blind trial of ethosuximide, lamotrigine, and valproate. Total problems score was the primary outcome measure.

RESULTS

A total of 382 participants at baseline, 310 participants at the week 16-20 visit, and 168 participants at the month 12 visit had CBCL data. At baseline, 8% (95% confidence interval [CI] 6%-11%) of children with CAE had elevated total problems scores (mean 52.9 ± 10.91). At week 16-20, participants taking valproic acid had significantly higher total problems (51.7 [98.3% CI 48.6-54.7]), externalizing problems (51.4 [98.3% CI 48.5-54.3]), attention problems (57.8 [98.3% CI 55.6-60.0]), and attention-deficit/hyperactivity problems (55.8 [98.3% CI 54.1-57.6]) scores compared to participants taking ethosuximide (46.5 [98.3% CI 43.4-49.6]; 45.8 [98.3% CI 42.9-48.7]; 54.6 [98.3% CI 52.4-56.9]; 53.0 [98.3% CI 51.3-54.8]). Lack of seizure freedom and elevated week 16-20 Conner Continuous Performance Test confidence index were associated with worse total problems scores. At month 12, participants taking valproic acid had significantly higher attention problems scores (57.9 [98.3% CI 55.6-60.3]) compared to participants taking ethosuximide (54.5 [95% CI 52.1-56.9]).

CONCLUSIONS

Pretreatment and ongoing behavioral problems exist in CAE. Valproic acid is associated with worse behavioral outcomes than ethosuximide or lamotrigine, further reinforcing ethosuximide as the preferred initial therapy for CAE.

CLINICALTRIALSGOV IDENTIFIER

NCT00088452.

CLASSIFICATION OF EVIDENCE

This study provides Class II evidence that for children with CAE, valproic acid is associated with worse behavioral outcomes than ethosuximide or lamotrigine.

Creating Inclusive School Environments

The neurobehavioural comorbidities associated with childhood epilepsy present significant physical challenges (i.e., excessive fatigue, memory impairment, headaches, visual impairments), emotional challenges (i.e., depression, anxiety), behavioural challenges (i.e., inattentiveness, distractibility, aggression), and social challenges (i.e., peer rejection, bullying, stigma) to children. Poor functioning within these domains can negatively affect academic success and school adjustment. As schools play a significant role in a child’s development, understanding how to support the social, psychological, and physical needs of these children is important. This article reviews literature examining the neurobehavioural comorbidities associated with childhood epilepsy and the barriers these conditions create to academic success and school adjustment. The article also provides recommendations based on the authors’ qualitative research about how best to support these children. Findings suggest that educating school communities about epilepsy and the challenges associated with it might promote inclusive school environments and mitigate negative school experiences. Findings also emphasize the need for an allied approach to the provision of support to ensure the needs of both students and faculty are met.

The Role of Self-Competence in Health-Related Quality of Life and Behavioral Functioning of Children with Tourette Syndrome

OBJECTIVE

To evaluate self-competence, health-related quality of life (HRQOL), and emotional/behavioral functioning in children with Tourette syndrome (TS) compared to normative data and to examine self-competence as a potential protective factor against poorer HRQOL and emotional/behavioral outcomes in this population.

METHOD

Thirty-nine children between the ages of 8 and 17 years and 72 caregivers participated in this study. Participants completed measures of children's HRQOL, emotional/behavioral functioning, and self-competence.

RESULTS

Participants reported significantly lower levels of emotional/behavioral functioning and HRQOL compared with norms of healthy children. No significant differences were found in domains of perceived self-competence. Social and general self-competence domains were significantly and positively correlated with most emotional and behavioral outcomes examined. Only social self-competence was significantly correlated with domains of HRQOL.

CONCLUSION

Self-competence, particularly in the social realm, may play a protective role against lower HRQOL and worse emotional and behavioral outcomes in children with TS. Children with this condition may benefit from self-competence-promoting interventions targeting children's perceptions of their own abilities.

Impaired performance on advanced Theory of Mind tasks in children with epilepsy is related to poor communication and increased attention problems

Children with epilepsy (CWE) have social difficulties that can persist into adulthood, and this could be related to problems with understanding others' thoughts, feelings, and intentions. This study assessed children's ability to interpret and reason on mental and emotional states (Theory of Mind) and examined the relationships between task scores and reports of communication and behavior. Performance of 56 CWE (8-16years of age) with below average IQ (n=17) or an average IQ (n=39) was compared with that of 62 healthy controls with an average IQ (6-16years of age) on cognition, language, and two advanced Theory of Mind (ToM) tasks that required children to attribute mental or emotional states to eye regions and to reason on internal mental states in order to explain behavior. The CWE-below average group were significantly poorer in both ToM tasks compared with controls. The CWE - average group showed a significantly poorer ability to reason on mental states in order to explain behavior, a difference that remained after accounting for lower IQ and language deficits. Poor ToM skills were related to increased communication and attention problems in both CWE groups. There is a risk for atypical social understanding in CWE, even for children with average cognitive function.

Social competence among well-functioning adolescents with epilepsy

PURPOSE

The aims of the study were to measure the social competence of well-functioning adolescents with epilepsy and compare it with that of their healthy peers as well as to analyze the effects of epilepsy-related variables on the social competence.

METHODS

Ninety well-functioning adolescents with epilepsy 12-19years of age were compared with healthy controls using the Achenbach Youth Self-Report Questionnaire measures of social competence. Within the group with epilepsy, the impact of duration of epilepsy, etiology, seizure frequency, seizure type, and antiepileptic drugs (AEDs) (monotherapy or polytherapy) on the above measures was also determined.

RESULTS

Twenty-five (27.8%) adolescents with epilepsy obtained Total Competence T scores in the clinical range, as opposed to only two (3.3%) of the healthy adolescents. There were statistically significant differences in the Activity and Social subscales and Total Competence T score between the group with epilepsy and the control group (p<0.05). Comparing T scores for epilepsy-related variables in the group with epilepsy, we found that there were statistically significant differences in all the social competence subscales regarding the seizure control and seizure types. No significant differences were obtained for other epilepsy-related variables: duration of epilepsy, onset of epilepsy, etiology, and AEDs.

CONCLUSION

Our results indicate that adolescents with epilepsy are less active in clubs, socialize less with their friends, and have a poorer school performance compared with their healthy peers. This study shows that adolescents with epilepsy are at an increased risk of having difficulties in social competence.

Cognitive impairment predicts social disability in persons with epilepsy

Introduction.Cognitive dysfunction is one of the main comorbidities of epilepsy which co-exists with seizures and contributes to the adverse impact of the disease on employment, education and interpersonal relationships. A fundamental question regarding cognitive dysfunction in epilepsy goes as follows: in comparison to seizures, what role does cognitive dysfunction play in causing social disability? The purpose of this review was to evaluate our understanding of the role cognitive impairment plays in social disability in persons with epilepsy (PWE). We systematically searched the medical literature and identified studies which assessed the impact of seizures and cognitive function on some aspect of social disability in PWE.

Results and Discussion.We identified 12 studies which adequately measured all variables in non-surgical cohorts, and 9 studies of cohorts following epilepsy surgery. We found evidence from non-surgical and from surgical series that cognitive variables strongly correlate with levels of social disability.

Conclusions.We conclude that efforts to better understand the origins of cognitive dysfunction in epilepsy and subsequently at developing treatment modalities will be needed in order to reduce the degree of social disability caused by the condition.

Treating anxiety disorders in children and adolescents with epilepsy: what do we know?

Children with epilepsy are at significant risk of psychiatric disorders, which can in turn negatively impact social skills development, academic achievement, and quality of life. The most commonly reported psychiatric comorbidities in pediatric epilepsy are ADHD, depression, and anxiety. The prevalence rates of anxiety disorders in pediatric epilepsy range from 5 to 49%, and in the general population, anxiety disorders are the most common psychiatric disorder in childhood. For the purposes of this review, anxiety disorders will be examined in order to 1) examine rates of anxiety disorders in children and adolescents with epilepsy, 2) review treatment options for anxiety disorders in children with epilepsy, and 3) identify future avenues for the development of evidence-based practices for the treatment of anxiety disorders in youth with epilepsy.

Social anxiety and self-concept in children with epilepsy: a pilot intervention study

PURPOSE

The purpose of this study was to assess the impact of a cognitive behavioral therapy (CBT) anxiety intervention on social phobia, social skill development, and self-concept.

METHOD

Fifteen children with epilepsy and a primary anxiety disorder participated in a CBT intervention for 12 weeks plus a 3-month follow-up visit. Children were assessed at baseline, week 7, week 12, and 3 months post treatment to measure changes in social phobia using the Screen for Child Anxiety Related Emotional Disorders (SCARED). Self-concept was also assessed by using the Piers-Harris Children's Self-Concept Scale II (Piers-Harris 2).

RESULTS

There was a significant reduction in symptoms of social phobia and improved self-concept at the end of the 12-week intervention and at the 3 month follow-up. Repeated measures ANOVA's of child ratings revealed significant change over time on the SCARED-Social Phobia/Social Anxiety subscale score (p=0.024). In terms of self-concept, significant change over time was detected on the Piers-Harris 2-Total score (p=0.015) and several subscale scores of Piers-Harris 2, including: Physical Appearance and Attributes (p=0.016), Freedom from Anxiety (p=0.005), and Popularity (p=0.003).

CONCLUSION

This pilot investigation utilized an evidenced based CBT intervention to reduce symptoms of social phobia, which in turn provided a vehicle to address specific social skills improving self-concept in children with epilepsy.

The social competence and behavioral problem substrate of new- and recent-onset childhood epilepsy

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 (p<0.05) from healthy controls, but did not differ from each other, across measures of behavior (Total Problems, Total Internalizing, Total Externalizing, and Other Problems including Thought and Attention Problems) or competence (Total Competence including School and Social). Similarly, children with specific syndromes of LRE and IGE differed significantly (p<0.05) from controls across measures of behavior (Total Problems, Total Internalizing, and Other Problems including Attention Problems) and competence (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).

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.

Patterns of cortical thickness and the Child Behavior Checklist in childhood epilepsy

The purpose of this investigation was to characterize the neuroanatomical correlates (cortical thickness) of variations in parent-reported Child Behavior Checklist (CBCL) scores. Ninety children with epilepsy (aged 8-18) underwent brain MRI, and their parents completed the CBCL. FreeSurfer-derived measures of cortical thickness were examined in relation to the CBCL broad and narrow band competence and behavioral problem scales, as well as the newer DSM-oriented scales. Parent reports of higher (better) social competence skills were associated with increased cortical thickness, especially in frontal regions. Parent reports of behavioral problems were associated with patterns of decreased cortical thickness that varied as a function of the specific behavioral issue under investigation. Congruence of patterns of cortical thinning between the DSM-oriented scales and conceptually related specific problem scales (e.g., ADHD Problems and Attention Problems) was generally weak. The parent-report version of the CBCL is associated with variations in cortical thickness among children with epilepsy. Anatomic abnormalities specific to selected competence and behavioral problem scales can be identified, with more reliable and robust patterns of thinning across scales assessing externalizing behaviors, with generally less prominent findings on scales assessing internalizing behaviors.

Social competence in children with epilepsy--a review

This systematic review focuses on definitions of social competence and assessment methods and provides an overview of the main findings in childhood epilepsy. A total of 45 studies drawn from MEDLINE and PsycINFO (1998-2010) and their reference lists met the selection criteria. Social competence was not defined in the studies reviewed. The study samples varied and consisted mostly of school-aged children. The majority of the studies focused on social adjustment and addressed problems in this area. Little is known about other aspects of social competence, namely social skills or social performance. A broader perspective on and definition of the assessment of social competence in children with epilepsy are proposed. More studies of the abilities underlying social competence, such as social and socio-cognitive skills, are needed in order to gain insight into the developmental pathways of social competence and protective factors for later development.

The relationship of coping behaviors to depressive symptoms in youth with epilepsy: an examination of caregiver and youth proxy report

Study aims were to explore evaluation and comparison of measures of coping and the relationship of epilepsy-specific coping responses to depressive symptoms in youth with epilepsy (YWE). Seventy-six YWE ages 9-17 completed the Children's Depression Inventory (CDI) and the Kidcope. Sixty-six caregivers reported on youth coping (CHIC) and seizure activity. Epilepsy variables were abstracted from electronic medical records. There were no significant correlations between the CHIC coping factors and individual Kidcope scores. Only one CHIC factor, "competence/optimism," was significantly negatively correlated with CDI. Regression analyses revealed a significant association between CDI and negative coping (Kidcope) after adjusting for sex, number of AEDs, and seizure severity. On the CDI, 27% of YWE endorsed suicidal ideation. Findings provide preliminary support for use of the Kidcope as a measure of negative epilepsy-specific coping. These results imply that youth coping and suicidal ideation are important to assess in relation to depressive symptoms and that youth report of these symptoms is particularly salient to the evaluation of youth functioning.

A long-term open-label extension study assessing cognition and behavior, tolerability, safety, and efficacy of adjunctive levetiracetam in children aged 4 to 16 years with partial-onset seizures

The objective of this study was to assess cognition and behavior in children (4-16 years; n = 103) with partial-onset seizures using the Leiter-R International Performance Scale and Achenbach Child Behavior Checklist. The study was a multicenter, open-label, noncomparative 48-week extension study (NCT00152516) of adjunctive levetiracetam (20-100 mg/kg/d, mean 50.2 mg/kg/d). Improvement from baseline in Leiter-R Memory Screen composite score at weeks 24 and 48 (mean [SD] change, +4.8 [12.6] and +4.5 [15.3]) was similar to changes observed with levetiracetam and placebo in a prior study. Child Behavior Checklist Syndrome scores improved from baseline at weeks 24 and 48 (total problems mean [SD] change, -9.3 [22.2] and -10.4 [23.4]). Adjunctive levetiracetam was well tolerated (most frequently reported central nervous system-related treatment-emergent adverse events: headache [24.3%], aggression [7.8%], irritability [7.8%]). Of the patients, 4.9% discontinued because of treatment-emergent adverse events. Levetiracetam provided good and sustained seizure control (median percentage reduction from baseline in partial-onset seizure frequency/wk during maintenance: 86.4%); 24.7% of patients had continuous seizure freedom from all seizure types for ≥40 weeks. In children, adjunctive levetiracetam was associated with long-term stability in cognitive functioning and improvement in emotional/behavioral functioning over time.

Child psychiatry

This paper first summarizes the main findings of clinical studies conducted over the past two and a half decades on psychopathology (i.e., psychiatric diagnoses, behavior and emotional problems) in children with new onset and chronic epilepsy both with and without intellectual disability who are treated medically and surgically. Although impaired social relationships are core features of the psychiatric disorders found in pediatric epilepsy, few studies have examined social competence (i.e., social behavior, social adjustment, and social cognition) in these children. There also is a dearth of treatment studies on the frequent psychiatric comorbidities of pediatric epilepsy, attention deficit hyperactivity disorder, anxiety disorders, and depression. Drs. Hamiwka and Jones then describe their current and planned studies on social competence and cognitive behavioral treatment of anxiety disorders, respectively, in these children and how they might mitigate the poor long-term psychiatric and social outcome of pediatric epilepsy.

Thought disorder and communication deviance as predictors of outcome in youth at clinical high risk for psychosis

OBJECTIVE

Given the fundamental role of thought disorder in schizophrenia, subtle communication disturbance may be a valuable predictor of subsequent development of psychosis. Here we examined the contribution of thought and communication disturbance to the prediction of outcome in adolescents identified as putatively prodromal for psychosis.

METHOD

Transcribed speech samples were elicited from 105 adolescents (54 identified as being at clinical high risk for a first episode of psychosis [CHR], and 51 demographically comparable comparison subjects) and coded for formal thought disorder (FTD) and linguistic cohesion. We then examined the association of baseline FTD/cohesion with conversion to psychosis and social and role outcome at follow-up, approximately 1 year later.

RESULTS

At baseline, CHR patients who subsequently converted to psychosis (CHR+) showed an elevated rate of illogical thinking and poverty of content (POC) in their speech, relative to both typically developing controls and CHR patients who did not convert to psychosis (CHR-). CHR+ youth also used significantly less referential cohesion at baseline, indicating that they provide fewer references to persons, objects, or events mentioned in preceding utterances. Multiple regression models indicated that, among measures of FTD/cohesion, illogical thinking was uniquely predictive of subsequent conversion to psychosis, whereas POC and referential cohesion were significant predictors of social and role functioning, respectively.

CONCLUSIONS

Despite the absence of fully psychotic symptoms, putatively prodromal individuals evidence signs of communication disturbance that are qualitatively similar to those seen in schizophrenia and are predictive of both conversion to psychosis and psychosocial outcome. These findings suggest that FTD measures have prognostic significance for at-risk youth.

Social skills in children with epilepsy: how do they compare to healthy and chronic disease controls?

Studies have shown poor long-term social outcomes in adults with childhood-onset epilepsy. Our goal was to compare social skills in children with epilepsy with those of healthy and chronic disease controls. Children (8-16 years) with epilepsy (n=59) were compared with age- and gender-matched children with chronic kidney disease (n=40) and healthy controls (n=41). Parents completed the Social Skills Rating System (SSRS) questionnaire. Children with epilepsy had significantly poorer SSRS total scores when compared with healthy controls (P=0.002); however, their scores did not differ from those of children with chronic kidney disease (P=0.52). Children with epilepsy were less cooperative (P=0.02), less assertive (P=0.004), and less responsible (P=0.05) and displayed poorer self-control (P=0.005) than healthy controls. Our results suggest that having a chronic disease plays a role in the social functioning of children with epilepsy. The impact of epilepsy itself on social functioning should be further elucidated through detailed prospective assessments over time.

Gender differences in risk-taking behaviour in youth with epilepsy: a Norwegian population-based study

OBJECTIVES

It is well known that behavioural problems and psychiatric disorders occur with greater prevalence in children and adolescents with epilepsy. Youth with epilepsy (YWE) may also be more susceptible to risk-taking behaviour, but this has seldom been studied. The aim of this study was to explore risk-taking behaviour in YWE.

MATERIAL AND METHODS

In this study, 19,995 young people (age range: 13-19 years) participated and completed an extensive questionnaire, including The Strengths and Difficulties Questionnaire self-report. A variable, risk-taking behaviour, was identified, including daily consumption of alcohol, substance abuse or having committed a criminal offence such as being in a fight with a weapon, committing a burglary or using threats to obtain money.

RESULTS

Two hundred and forty-seven youths reported currently having, or having had, epilepsy (lifetime prevalence: 1.2%). Of these, 8.3% reported daily alcohol consumption (1.0% in controls; P<0.001), 12.4% had tried illegal substances (5.5% of controls; P<0.001), and 19.7% had committed criminal offences (8.5% in controls; P<0.001). A gender difference was found: girls with epilepsy did not exhibit risk-taking behaviour more frequently than controls, but having epilepsy was a risk factor for such behaviour in boys (OR: 3.2).

CONCLUSION

Boys with epilepsy exhibit risk-taking behaviour more frequently than controls. Other risk factors for this behaviour were living with a single parent, low family income and psychiatric symptoms. This behavioural association should be addressed as it probably contributes to the negative social outcomes that frequently occur in the adult epilepsy population.

Personality traits and social behaviors predict the psychological adjustment of Chinese people with epilepsy

Very little is known about the psychosocial correlates of psychological morbidity among Chinese people with epilepsy (PWE). No studies have investigated the association between social relationships and psychological morbidity, while most studies examined only the negative impact of maladaptive personalities on psychological adjustment in PWE. This study examined the association of psychological morbidity with a broad array of personality traits and social skills in a sample of 54 Chinese PWE. Respondents completed the Temperament and Character Inventory (TCI), the Social Performance Survey Schedule (SPSS), and the Hospital Anxiety and Depression Scale (HADS) via semi-structured interview. Regression analyses revealed that, independent of demographic and medical variables and perceived impact, Harm Avoidance was positively associated with anxiety and depression whereas Self-Directedness was negatively associated with anxiety and depression; that Cooperativeness was inversely associated with anxiety. Social skills were inversely associated with depression whereas negative social skills were inversely associated with anxiety. Clinical implications of adaptive personality traits and social skills functioning are discussed.

Assessment of behavioral and emotional functioning using standardized instruments in children and adolescents with partial-onset seizures treated with adjunctive levetiracetam in a randomized, placebo-controlled trial

A randomized, double-blind, placebo-controlled study (N01103, NCT00105040) evaluated behavioral and emotional effects of adjunctive levetiracetam (LEV) treatment in children and adolescents (4-16years old) with uncontrolled partial-onset seizures. Patients received adjunctive LEV 20-60mg/kg/day (n=64) or placebo (n=34) for 12weeks. The Achenbach Child Behavior Checklist (CBCL) and portions of the Child Health Questionnaire-Parent Form 50 (CHQ-PF50) were used to assess behavioral and emotional functioning at baseline and end of the treatment period. Worsening of the mean CBCL Aggressive Behavior score occurred for LEV but not placebo, leading to similar results for Externalizing Syndromes and Total Problems (all P<0.05 vs placebo). The change in the CBCL Activities Competence score favored LEV (P<0.05). These results are in line with the known safety profile of LEV.

Behaviour profiles after tuberculous meningitis

The purpose of the study was to investigate child behaviour in children who recovered from tuberculous meningitis (TBM) and to compare behaviour profiles of stage II and stage III patients. The mean age of the cohort of 74 children at the time of evaluation was 10 years and 7 months. At follow-up all patients underwent a thorough neurological examination and a psychometric test battery, which included intellectual assessment and evaluation of behaviour by means of the CBCL/6-18. Results indicated elevated mean scores (T > 60) on CBCL/6-18 scales which measure problems with anxiety, depression, attention, social relationships, disruptive and rule-breaking behaviour. Mean CBCL scores of stage III patients were significantly higher than the mean scores of stage II patients on scales which measure social problems, disruptive and rule-breaking behaviour. In addition, problems with conduct, attention, attention-deficit/hyperactivity problems, affective problems as well as the total problem scores were more pronounced in the patients with stage III TBM. We conclude that general behavioural disinhibitions as well as internalized emotional disorder probably are long-term complications in more than 10% of the survivors of TBM.

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.

Emotional and behavioural problems in adolescents with intellectual disability with and without chronic diseases

BACKGROUND

Adolescents with intellectual disability (ID) (ID-adolescents) and adolescents with chronic diseases are both more likely to have emotional and behavioural problems. The aim of this study was to assess the association between chronic diseases in ID-adolescents and emotional and behavioural problems in a large school-based sample.

METHODS

We obtained data on 1044 ID-adolescents, aged 12-18 years, attending secondary schools in the Netherlands. Parents of the adolescents completed the Dutch version of the Strengths and Difficulties Questionnaire and questions about chronic diseases in their child and about the background of the child.

RESULTS

Prevalence rates of emotional and behavioural problems were generally high in ID-adolescents with chronic diseases (45%), compared with ID-adolescents without chronic diseases (17%). The likelihood of emotional and behavioural problems was high in ID-adolescents with two [odds ratios (OR) 4.47; 95% CI: 2.97-6.74] or more than two chronic diseases (OR 8.01; 95% CI: 5.18-12.39) and for ID-adolescents with mental chronic diseases (OR 4.56; 95% CI: 3.21-6.47). Also ID-adolescents with somatic chronic diseases had a high likelihood of emotional and behavioural problems (OR 1.99; 95% CI: 1.33-2.99), in particular in the combination of somatic and mental chronic diseases (OR 5.16; 95% CI: 3.46-7.71).

CONCLUSIONS

The current study showed that chronic diseases in ID-adolescents, in particular mental chronic diseases, largely increase the likelihood of emotional and behavioural problems. This should be taken in the provision and planning of care for ID-adolescents.

How can cognitive status predispose to psychological impairment?

A significant proportion of people report cognitive impairments, in particular memory problems, and express concern that these impairments will worsen with the passage of time. Unfortunately, the lack of well-designed studies has meant that disentangling the relative influences of factors likely important in the development and course of neuropsychological impairment has proved problematic. In addition to experiencing neuropsychological difficulties, people with epilepsy have to manage the psychosocial sequalae often associated with epilepsy. A diagnosis of epilepsy can have negative implications for quality of life and be associated with an increased risk of psychosocial problems; and individuals with epilepsy do not all experience its impact equally. The impacts of neuropsychological functioning on quality of life have only been rarely investigated, but there is some evidence to suggest that quality of life may correlate better with self-perceived cognitive difficulties than with scores on formal tests of cognitive functioning.

Social competence of preschool children with epilepsy

The aims of this study were to describe the social competence of 3- to 6-year-old children with epilepsy (n=26) compared with that of age- and gender-matched healthy controls (n=26). Social competence was assessed with the Vineland Social Maturity Scale, Conners' Parent Rating Scales-Revised, and the Child Behavior Checklist. The results indicate that the children with epilepsy, especially with complicated epilepsy, had fewer age-appropriate social skills and more attention and behavior problems than the healthy children, as reported by parents. It is possible that the lack of age-appropriate social skills and the presence of attention problems predispose to behavioral problems. Also, epilepsy-related factors impaired the achievement of social competence. This study shows that the preschool children with complicated, early-onset epilepsy are at increased risk of difficulties in social competence.

Thought disorder and frontotemporal volumes in pediatric epilepsy

The aim of this study was to determine if volumes of frontotemporal regions associated with language were related to thought disorder in 42 children, aged 5-16 years, with cryptogenic epilepsy, all of whom had complex partial seizures (CPS). The children with CPS and 41 age- and gender-matched healthy children underwent brain MRI scans at 1.5 T. Tissue was segmented, and total brain, frontal lobe, and temporal lobe volumes were computed. Thought disorder measures, IQ, and seizure information were collected for each patient. The subjects with CPS had more thought disorder, smaller total gray matter and orbital frontal gray matter volumes, as well as larger temporal lobe white matter volumes than the control group. In the CPS group, thought disorder was significantly related to smaller orbital frontal and inferior frontal gray matter volumes, increased Heschl's gyrus gray matter volumes, and smaller superior temporal gyrus white matter volumes. However, significantly larger orbital frontal gyrus, superior temporal gyrus, and temporal lobe gray matter volumes and decreased Heschl's gyrus white matter volumes were associated with thought disorder in the control group. These findings suggest that thought disorder might represent a developmental disability involving frontotemporal regions associated with language in pediatric CPS.

Consensus statement: the evaluation and treatment of people with epilepsy and affective disorders

Affective disorders in people with epilepsy (PWE) have become increasingly recognized as a primary factor in the morbidity and mortality of epilepsy. To improve the recognition and treatment of affective disorders in PWE, an expert panel comprising members from the Epilepsy Foundation's Mood Disorders Initiative have composed a Consensus Statement. This document focuses on depressive disorders in particular and reviews the appearance and treatment of the disorder in children, adolescents, and adults. Idiosyncratic aspects of the appearance of depression in this population, along with physiological and cognitive issues and barriers to treatment, are reviewed. Finally, a suggested approach to the diagnosis of affective disorders in PWE is presented in detail. This includes the use of psychometric tools for diagnosis and a stepwise algorithmic approach to treatment. Recommendations are based on the general depression literature as well as epilepsy-specific studies. It is hoped that this document will improve the overall detection and subsequent treatment of affective illnesses in PWE.

Social skills problems in children with epilepsy: prevalence, nature and predictors

To determine the prevalence, nature, and predictors of social skills impairment in children with epilepsy, 101 parents completed the Social Skills Rating System, the Child Behavior Checklist, a general health questionnaire for both their child with epilepsy (aged 3-17) and his or her sibling, a quality-of-life assessment for the child with epilepsy, and Family Assessment Measure III. Epilepsy-specific variables were recorded for each case. Although children with epilepsy had poorer social skills (P<0.05) and were less assertive (P<0.006) than their siblings, the proportion with clinically significant social skills deficits was low and did not differ between groups (13% vs 7%, P=0.12). Neurological factors were related to social skills, but only presence of a learning disability (odds ratio=8.64, 95% CI=1.87-39.98) and abnormal family function (odds ratio=8.75, 95% CI=1.42-53.83) were strongly predictive of social skills impairment. Lower social skills were moderately correlated with epilepsy-specific and global quality of life (P<0.001).
