Neurobehavioral comorbidities in children with active epilepsy: a population-based study

Attention-deficit/hyperactivity disorder in children with epilepsy: A systematic review and meta-analysis of prevalence and risk factors

OBJECTIVE

To evaluate the prevalence of and risk factors for attention-deficit/hyperactivity disorder (ADHD) in children with epilepsy (CWE).

METHODS

We conducted a systematic search in PubMed and Embase for the meta-analysis. The pooled prevalence of ADHD was calculated using a random-effects model; subgroup analyses were performed to explore heterogeneity. We collected raw data from articles reporting potential risk factors, which were included in the subsequent risk factor analysis.

RESULTS

Forty-six articles met the inclusion criteria for the meta-analysis, which showed a pooled ADHD prevalence of 30.7% in CWE, with a predominance of the inattentive subtype of ADHD; the heterogeneity of prevalence was related to population source/study setting (clinic based, community based, or database based) and method of ADHD diagnosis (with or without clinical review). Risk factors for ADHD in epilepsy included younger age, intellectual/developmental disabilities, a family history of epilepsy, earlier epilepsy onset, absence epilepsy, more frequent seizures, and polytherapy; In contrast, risk factors such as sex, generalized epilepsy or seizures, epilepsy etiology, and electroencephalogram abnormalities were not significantly associated with the occurrence of ADHD.

SIGNIFICANCE

The prevalence of ADHD in CWE is high and several potential risk factors are associated with it. This study contributes to a better understanding of ADHD in epilepsy for screening and treatment.

PLAIN LANGUAGE SUMMARY

This systematic review summarizes the prevalence of attention-deficit/hyperactivity disorder (ADHD) occurring in children with epilepsy and analyses the risk factors for comorbid ADHD in epilepsy. By reviewing 46 articles, we concluded that the overall prevalence of ADHD in children with epilepsy was 30.7% and that intellectual/developmental disabilities were the most significant risk factor for combined ADHD in children with epilepsy. This study provides a wealth of information on comorbid ADHD in epilepsy, which will help clinicians identify and treat potential ADHD in children with epilepsy in a timely manner.

Mental health in secondary school-aged children with epilepsy and their primary caregivers: A case control study

PURPOSE

To describe the prevalence and associated factors of mental health problems in secondary school-aged (11-16 years) children with epilepsy and their primary caregivers compared to a control group without epilepsy.

METHODS

Children with epilepsy (n = 60), controls (n = 49), and caregivers (n = 60 epilepsy and n = 49 control group) completed a measure of the child's mental health (Strengths and Difficulties Questionnaire; SDQ). Primary caregivers in both groups completed a measure of their own mental health (Depression, Anxiety, and Stress Scale-21; DASS-21). Factors associated with child and caregiver mental health in the epilepsy group were explored using linear regression.

RESULTS

There were no significant differences between the epilepsy and control group regarding age, gender, ethnicity and socioeconomic status. A higher proportion of children with epilepsy scored in the at-risk range on the SDQ indicating more mental health problems than the control group, as reported by the children (45% vs. 24 %) (p = 0.026) and caregivers (52% vs. 14 %) (p < 0.001). Primary caregivers of children with epilepsy had more symptoms of depression (p = 0.001), anxiety (p = 0.028) and stress (p = 0.019) than caregivers in the control group. Children with epilepsy with greater motor coordination problems had greater mental health difficulties. Children with epilepsy with more mental health difficulties had caregivers with more difficulties and caregivers of children with earlier onset of seizures had more mental health difficulties.

CONCLUSIONS

Epilepsy confers a high risk for mental health problems in adolescents and their primary caregivers. There is a need to better understand the relationship between caregiver and child mental health difficulties in epilepsy.

Screening and treatment of anxiety symptoms within an interdisciplinary comprehensive epilepsy center

Youth with epilepsy (YWE) are at elevated risk for anxiety, yet anxiety is often undetected and understudied in this population. Most research on anxiety in YWE is based on parent proxy-report and broad-band measures with limited sensitivity. The aim of the current study was to: 1) examine rates of anxiety symptoms in YWE using a diagnosis-specific, self-report measure of anxiety symptoms, 2) assess differences in anxiety symptoms by sociodemographic and medical variables, and 3) evaluate changes in anxiety symptoms following a brief behavioral health intervention delivered within an interdisciplinary epilepsy clinic visit. As part of routine clinical care, 317 YWE [Mage=13.4+2.5 years (range 7-19 years); 54% female; 84% White: Non-Hispanic] completed the Multidimensional Anxiety Scale for Children, self-report (MASC-10), with a subset completing the MASC-10 at a second timepoint (n=139). A retrospective chart review was completed and sociodemographic, medical variables and behavioral health interventions were collected. Thirty percent of YWE endorsed elevated anxiety symptoms, with higher rates in those who were younger. YWE who received a behavioral health intervention for anxiety (n=21) demonstrated greater decreases in anxiety symptoms from Time 1 to Time 2 compared to those who did not receive a behavioral intervention (n=108). The integration of psychologists into pediatric epilepsy clinics may have allowed for early identification of anxiety symptoms, as well behavioral interventions to address these symptoms, which has the potential to decrease the need for more intensive services.

"One size does not fit all" - Barriers to and facilitators of physical activity in adolescents with epilepsy

OBJECTIVE

To explore the barriers to physical activity and to identify the support needed to facilitate physical activity in adolescents with epilepsy (AWE).

METHODS

AWE (aged 11-16 years) and their caregivers completed survey-based open questions regarding perceived barriers to, and facilitators of physical activity in young people with epilepsy. The responses were analysed using Thematic Analysis.

RESULTS

Themes concerning barriers to physical activity included concerns about seizure safety, general anxiety and anxiety related to seizures, stigma/negative attitudes associated with having epilepsy, tiredness, and perceived lack of physical competence. Themes regarding the support needed to facilitate physical activity included better education amongst staff/coaches about epilepsy (e.g., seizure management/prevention, associated fatigue/tiredness), improvements in societal attitudes towards epilepsy, flexibility/tailoring of activities to the child's needs (e.g., need for breaks), and peer support for young people with epilepsy to encourage engagement in physical activity.

CONCLUSIONS

There is a perception among AWE and caregivers, that significant barriers exist with regard to engaging in physical activity for young people with epilepsy. Barriers are related to concerns about seizure management but also wider safety and social issues. A number of facilitators were identified to promote physical activity engagement in AWE, including education for staff and caregivers, peer support, and tailoring activities to the adolescent's needs. There is a need to develop interventions to reduce barriers to physical activity in young people with epilepsy.

Sleep and functional outcomes in children and adolescents with epilepsy: A scoping review

AIM

In children and adolescents with epilepsy (CAWE), disturbed sleep and functional difficulties are frequently present, but their relationship is unclear. In this scoping review we aimed to explore associations between sleep and functional outcomes in CAWE.

METHOD

We registered the protocol with open science framework and conducted the review according to the PRISMA Extension for Scoping Reviews. We searched Medline, Embase, PsycINFO and PubMed for original studies reporting on relations between sleep and functional outcomes (adaptive/quality of life, behavioural/mood, cognitive & academic) in CAWE. To assess the quality of studies we used an extended version of the checklist employed by Winsor and colleagues [1].

RESULTS

We identified 14 studies that included 1,785 CAWE and 1,260 control children, with a mean age of 9.94 and 10.13 years, respectively. The studies were highly heterogeneous with respect to samples, epilepsy variables, and methods used to assess sleep and functional outcomes. The quality of studies was medium. Associations between sleep and adaptive/quality of life, behavioural/mood, cognitive and academic outcomes were examined in 2, 10, 6, and 0 studies, respectively. Across studies, in CAWE, greater sleep disturbances were related to worse behavioural/mood outcomes, ranging from depression/anxiety to ADHD symptoms. Sleep disturbances did not consistently relate to cognitive outcomes, but they related to worse adaptive outcomes in both studies that examined their relationship.

CONCLUSIONS

Our study provides evidence of relationship between disturbed sleep and behavioural/mood difficulties, which alerts to the need for careful evaluation and treatment of sleep disturbances in CAWE. Our study also highlights the need to examine relationships between sleep and other functional outcomes in CAWE, as studies conducted in the general population suggest that sleep disturbances may be modifiable and associated with improved functional outcomes.

Bringing nutritional ketosis to the table as an option for healing the pediatric brain

Our core premise is that personalized variations of a ketogenic diet are likely to benefit pediatric patients with neuropsychiatric symptoms across multiple domains. Although pediatric epilepsy is currently a well-accepted indication for a strict ketogenic diet, there is a dearth of knowledge and therefore clinical guidelines upon which to recommend nutritional ketosis for pervasive pediatric conditions such as autism spectrum disorder and ADHD, even when comorbid epilepsy is present. However, there are published cohort studies and current clinical trials implementing medical ketogenic therapies for cognitive impairment, psychiatric comorbidities, motor disability, and even neuroinflammation. As holistic practitioners, it is imperative that we consider the health of a child in its entirety - and additionally offer the ketogenic diet as a therapeutic option when it may be synergistic in treating extra-neurologic diseases such as obesity. While there are uniquely pediatric potential adverse side effects such as linear growth deceleration and micronutrient deficiencies, previous trials in epilepsy and our center's experience have already proven the ketogenic diet to be a low-risk intervention when optimized with appropriate patient monitoring and support.

Factors associated with changes in the quality of life and family functioning scores of primary caregivers of children and young people with primary brain tumors in Karachi, Pakistan: a prospective cohort study

BACKGROUND

There are limited data available, particularly in low- and middle-income countries (LMICs), on the long-term quality of life (QoL) and family functioning of primary caregivers of children and young people (CYPs) affected by primary brain tumors (PBTs). This study aimed to assess the factors associated with the mean change in QoL and family functioning scores of primary caregivers of CYP patients with PBTs 12 months posttreatment.

METHODS

This prospective cohort study enrolled CYPs aged 5-21 years with newly diagnosed PBTs and their primary caregivers. The study was carried out between November 2020 and July 2023. The primary caregivers of CYPs were recruited from two major tertiary care centers in Karachi, Pakistan. The primary caregivers QoL were assessed by the Pediatric Quality of Life Inventory (PedsQL) Family Impact Module. The assessment was undertaken by a psychologist at the time of diagnosis and 12 months posttreatment. The data were analyzed with STATA version 12.

RESULTS

Forty-eight CYPs with newly diagnosed PBTs and their primary caregivers (46 mothers and 2 fathers) were enrolled. At 12 months posttreatment, 25 (52%) CYPs and their primary caregivers (mothers) were reassessed, and 23 (48%) were lost to follow-up. On multivariable analysis, a significant decrease in mothers' mean 12-month posttreatment QoL and family functioning scores was associated with CYP having posttreatment seizures (beta= -10.2; 95% CI: -18.4 to -2.0) and with the financial burden associated with the CYP's illness (beta= -0.3; 95% CI: -0.4 to -0.1). However, in those cases where CYP had higher posttreatment quality of life scores (beta = 0.4; 95% CI = 0.1, 0.6) and posttreatment higher verbal intelligence scores (beta = 0.1; 95% CI = 0.01, 0.3), the mothers' QoL and family functioning scores were significantly greater.

CONCLUSION

We found a significant decrease in QoL of mothers who had a high financial burden and whose CYP had posttreatment seizures. However, those whose CYPs had higher posttreatment verbal intelligence scores and quality of life scores had significantly greater QoL scores. Identification of the factors that influence primary caregivers QoL has the potential to aid in the development of targeted strategies to alleviate stressors and improve the overall quality of life for primary caregivers and their children who are at high risk.

Emotional intelligence in children with epilepsy

Objective

Epilepsy is a prevalent neurological disorder in the pediatric population, often accompanied by comorbidities, drug-related burdens, and psychosocial issues. Emotional intelligence (EI) is a crucial aspect of neurocognitive functioning that may be impaired in various clinical conditions. This study aimed to assess EI and its associated risk factors in children with epilepsy.

Methods

In a case-control design, we recruited 47 children with epilepsy (37 males, mean age 10.5 ± 3.1 years) and age- and gender-matched controls. Participants were evaluated using the Emotional Quotient Inventory: Youth Version (EQ-I:YV). We included risk factors, including comorbidities, perinatal complications, epilepsy characteristics, and magnetic resonance imaging results to predict EI.

Results

Results indicate that children with epilepsy demonstrated significantly lower EI scores compared to controls (Total EQ score: p = 0.031, intrapersonal: p < 0.001, adaptability: p = 0.03, and general mood: p < 0.001). Multiple linear regression analysis indicated that lower total EQ scores were associated with the number of anti-epileptic drugs, age, seizure frequency, MRI abnormalities, aura, and early onset of seizures.

Conclusions

The study provides evidence that children with epilepsy exhibit lower EQ scores than control group, with notable differences in intrapersonal skills, adaptability, and general mood. Additionally, age, and some seizure-related factors predicted decreased total EQ scores. These findings emphasize the need to consider EI in the context of pediatric epilepsy, as impaired EI may contribute to further psychosocial challenges faced by affected children.

Autism and attention-deficit/hyperactivity disorder in children with Dravet syndrome: A population-based study

AIM

To identify on a population basis the prevalence of autism and attention-deficit/hyperactivity disorder (ADHD) in children with Dravet syndrome and factors associated with symptoms of autism and ADHD.

METHOD

Forty-one of 48 children with Dravet syndrome living in Sweden, born between 1st January 2000 and 31st December 2018 underwent assessment including measures of autism and ADHD. Diagnoses of autism and ADHD were made with respect to DSM-5 criteria. Factors associated with features of autism and ADHD were analysed via regression.

RESULTS

Twenty-five of the 41 children fulfilled DSM-5 criteria for autism spectrum disorder and 12 of 37 children considered for an ADHD diagnosis fulfilled DSM-5 criteria for ADHD. Severe intellectual disability was significantly associated with a greater degree of autistic features (p < 0.001) and a DSM-5 diagnosis of autism spectrum disorder (p = 0.029). Younger children had significantly more features of ADHD (p = 0.004) and features of inattention were significantly more common than features of hyperactivity/impulsivity (p < 0.001).

INTERPRETATION

Children with Dravet syndrome often have significant features of autism and ADHD, primarily inattentive type. Screening for autism and ADHD should be routine in children with Dravet syndrome.

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.

Socioeconomic status in adulthood of children with and without a history of seizures: A retrospective cohort study

OBJECTIVE

Compare adulthood socioeconomic status for children with and without a history of seizures.

METHODS

Retrospective cohort study using Aberdeen Children of the Nineteen Fifties (ACONF) data comprising children born 1950-1956 attending primary school 1962-1964, with follow-up data collected in 2001. Adulthood socioeconomic status was based on registrar general measure of occupational social class and categorised as high or low. We adjusted for potentially confounding variables including childhood socioeconomic status, behavioural issues (Rutter A/B scores), biological sex, school test scores, educational attainment, parental engagement with education, peer-status in school, and alcohol use in adulthood. A multivariate binary logistic regression was performed to estimate the adjusted association between children with a history of seizures of any type (for example febrile seizures, or provoked seizures of any other etiology or seizures in the context of epilepsy) or severity and adult socioeconomic status. Multiple imputation using the Monte-Carlo-Markov-Chain method accounted for missing data.

RESULTS

Pooled estimates (N = 2,208) comparing children with a history of seizures (n = 81) and children without a history of seizures (n = 2,127) found no differences between these cohorts in terms of adulthood socioeconomic status in both unadjusted (Odds Ratio (OR) 1.45 [95 % CI 0.71-2.96], p = 0.31) and adjusted (1.02 [0.46, 2.24], p = 0.96) analyses. Compared to males, females were at increased odds of having a lower socioeconomic status in adulthood (1.56 [1.13-2.17], p = 0.01).Compared to those with low educational attainment, those with moderate (0.32 [0.21, 0.48], p < 0.001) and high (0.12 [0.07, 0.20], p < 0.001) educational attainment were at reduced odds of having a lower socioeconomic status in adulthood.

CONCLUSION

Cognitive problems in childhood (using educational attainment and scores on primary school tests proxy markers for cognition) rather than a history of seizures per se, were associated with lower SES in a population of adults born 1950-56 in Aberdeen. This relationship may be different depending on the time in history and nation/region of study. Given the changes in health, education and social support in the management of children with seizures over time, it would be of interest to investigate outcomes in a contemporary cohort. Such studies should ideally have validated diagnoses of seizures, details on seizure characteristics such as seizure type and severity, and a large sample size using national data.

Attention-deficit hyperactivity disorder in adults with epilepsy: An indirect relationship with suicide risk

PURPOSE

Studies on attention-deficit hyperactivity disorder (ADHD) are scarce in adults with epilepsy. This study aimed to investigate the risk factors for ADHD and determine whether ADHD is directly associated with the risk of suicide in adults with epilepsy.

METHODS

ADHD was assessed using the Structured Clinical Interview for the DSM-5 Disorders Clinical Version. The Mini International Neuropsychiatric Interview (MINI) Plus 5.0.0, Neurological Disorders Depression Inventory for Epilepsy (NDDIE), and Generalized Anxiety Disorder-7 (GAD-7) were also used. Suicide risk was defined as a MINI suicidality score of ≥ 1. Stepwise logistic regression and mediation analyses were conducted.

RESULTS

Of the 157 adults with epilepsy, 19 (12.1 %) were diagnosed with ADHD, including inattentive (5.7 %), hyperactive (3.8 %), and combined (2.5 %) types. Thirty-two subjects (20.4 %) had a risk of suicide. ADHD was insignificantly associated with any epilepsy-related factors. The diagnosis of ADHD was not associated with suicide risk independent of NDDIE ≥ 14 and GAD-7 ≥ 7. Mediation effects of ADHD on suicidality using NDDIE ≥ 14 (odds ratio [OR] 2.850, 95 % confidence interval [CI] 1.398-5.811, p = 0.004) or GAD-7 ≥ 7 (OR 3.240, 95 % CI 1.537-6.828, p = 0.002) were statistically significant, with the proportion mediated being 84.5 % or 92.0 % of the total ADHD effect, respectively. These models were adjusted for age, sex, and composite epilepsy severity scores.

CONCLUSIONS

ADHD was diagnosed in 12.1% of adults with epilepsy and was not associated with any epilepsy-related factors. ADHD was indirectly associated with the risk of suicide resulting from depression and anxiety in adults with epilepsy.

Sleep disorders in children with epilepsy

INTRODUCTION

Children with epilepsy present greater prevalence of sleep disorders than the general population. Their diagnosis is essential, since epilepsy and sleep disorders have a bidirectional relationship.

OBJECTIVE

Determine the incidence of sleep disorders and poor sleep habits in children with epilepsy.

METHODS

We conducted a cross-sectional study of patients under 18 years of age with epilepsy, assessing sleep disorders using the Spanish-language version of the Sleep Disturbance Scale for Children (SDSC), and sleep habits using an original questionnaire.

RESULTS

The sample included 153 patients. Eighty-four percent of our sample presented some type of sleep alteration. The most frequent alterations were sleep-wake transition disorders (53%), sleep initiation and maintenance disorders (47.7%), and daytime sleepiness (44.4%). In 70% of cases, the patients' parents reported that their child "slept well," although sleep disorders were detected in up to 75.7% of these patients. Many patients had poor sleep habits, such as using electronic devices in bed (16.3%), requiring the presence of a family member to fall asleep (39%), or co-sleeping or sharing a room (23.5% and 30.5%, respectively). Those with generalised epilepsy, refractory epilepsy, nocturnal seizures, and intellectual disability were more likely to present sleep disorders. In contrast, poor sleep habits were frequent regardless of seizure characteristics.

CONCLUSIONS

Sleep disorders and poor sleep habits are common in children with epilepsy. Their treatment can lead to an improvement in the quality of life of the patient and his/her family, as well as an improvement in the prognosis of epilepsy.

Diagnosis, epilepsy treatment and supports for neurodevelopment in children with Dravet Syndrome: Caregiver reported experiences and needs

BACKGROUND

Dravet syndrome is a rare infantile onset epilepsy syndrome encompassing treatment resistant epilepsy and neurodevelopmental difficulties. There is limited data regarding caregiver experiences of diagnosis, treatment and supports for the associated neurodevelopmental problems.

METHOD

Semi-structured interviews were conducted with caregivers of 36/48 children (75% of total population in Sweden) with Dravet syndrome. Data was analysed using thematic analysis.

RESULTS

Regarding the diagnostic experience, themes were: Delays in diagnostic process, genetic testing not optimal, communication of Dravet syndrome diagnosis and support and information soon after diagnosis. Caregivers felt that delays in diagnosis and testing could have been avoided whilst experiences of communication of diagnosis and support after diagnosis varied. In terms of treatment for seizures, the themes were: Satisfied with treatment, emergency treatment, treatment with antiseizure medications, strategies to control seizures via temperature regulation/avoidance of infections and use of equipment and aids. Caregivers were in the main accepting that seizures in Dravet syndrome are very difficult to treat and that seizure freedom is often an unachievable goal. Many felt frustrated that they were expected to take responsibility with respect to choice of medication. They often employed strategies (e.g., avoidance of physical activity) to reduce seizures or their impact. In terms of supports for neurodevelopmental problems, the themes were: Struggled to access support, lack of integrated healthcare and satisfaction with school. Many caregivers felt that accessing necessary supports for their children and developmental and behavioural needs was a struggle and that the provision of support often lacked integration e.g., lack of collaboration between child's disability service and school. Caregivers also expressed a desire that there would be better knowledge of Dravet syndrome in emergency departments and schools, that care would be better integrated and that there would be more supports for assessment and interventions regarding the associated neurodevelopmental problems.

CONCLUSION

The responses of caregivers of children with Dravet syndrome highlight the need for supports from diagnosis for both epilepsy and neurodevelopmental problems. Good examples of provision were identified but parents often felt they lacked support and support often came from providers who lacked knowledge of the syndrome. Collaboration between medical, disability and school services was often lacking.

Expanding eligibility for intracranial electroencephalography using Dexmedetomidine Hydrochloride in children with behavioral dyscontrol

INTRODUCTION

Invasive intracranial electroencephalography (IEEG) is advantageous for identifying epileptogenic foci in pediatric patients with medically intractable epilepsy. Patients with behavioral challenges due to autism, intellectual disabilities, and hyperactivity have greater difficulty tolerating prolonged IEEG recording and risk injuring themselves or others. There is a need for therapies that increase the safety of IEEG but do not interfere with IEEG recording or prolong hospitalization. Dexmedetomidine Hydrochloride's (DH) use has been reported to improve safety in patients with behavioral challenges during routine surface EEG recording but has not been characterized during IEEG. Here we evaluated DH administration in pediatric patients undergoing IEEG to assess its safety and impact on the IEEG recordings.

METHODS

A retrospective review identified all pediatric patients undergoing IEEG between January 2016 and September 2022. Patient demographics, DH administration, DH dose, hospital duration, and IEEG seizure data were analyzed. The number of seizures recorded for each patient was divided by the days each patient was monitored with IEEG. The total number of seizures, as well as seizures per day, were compared between DH and non-DH patients via summary statistics, multivariable linear regression, and univariate analysis. Other data were compared across groups with univariate statistics.

RESULTS

Eighty-four pediatric patients met the inclusion criteria. Eighteen (21.4 %) received DH treatment during their IEEG recording. There were no statistical differences between the DH and non-DH groups' demographic data, length of hospital stays, or seizure burden. Non-DH patients had a median age of 12.0 years (interquartile range: 7.25-15.00), while DH-receiving patients had a median age of 8.0 years old (interquartile range: 3.00-13.50) (p = 0.07). The non-DH cohort was 57.6 % male, and the DH cohort was 50.0 % male (p = 0.76). The median length of IEEG recordings was 5.0 days (interquartile range: 4.00-6.25) for DH patients versus 6.0 days (interquartile range: 4.00-8.00) for non-DH patients (p = 0.25). Median total seizures recorded in the non-DH group was 8.0 (interquartile range: 5.00-13.25) versus 15.0 in the DH group (interquartile range: 5.00-22.25) (p = 0.33). Median total seizures per day of IEEG monitoring were comparable across groups: 1.50 (interquartile range: 0.65-3.17) for non-DH patients compared to 2.83 (interquartile range: 0.89-4.35) (p = 0.25) for those who received DH. Lastly, non-DH patients were hospitalized for a median of 8.0 days (interquartile range: 6.00-11.25), while DH patients had a median length of stay of 7.00 days (interquartile range: 5.00-8.25) (p = 0.27). No adverse events were reported because of DH administration.

CONCLUSIONS

Administration of DH was not associated with adverse events. Additionally, the frequency of seizures captured on the IEEG, as well as the duration of hospitalization, were not significantly different between patients receiving and not receiving DH during IEEG. Incorporating DH into the management of patients with behavioral dyscontrol and intractable epilepsy may expand the use of IEEG to patients who previously could not tolerate it, improve safety, and preserve epileptic activity during the recording period.

Self-reported attention and hyperactivity symptoms among adults with epilepsy

BACKGROUND

 Patients with epilepsy (PWE) frequently have comorbid psychiatric disorders, the most common of which are depression and anxiety. Attention deficit disorder with hyperactivity (ADHD) is also more frequent among PWE, though that condition has been scarcely studied among the adult PWE population.

OBJECTIVE

 This study aimed to compare the presence of ADHD symptoms between adult PWE and the general population.

METHODS

 This was an observational case-control study. Ninety-five adult PWE from a tertiary center in southern Brazil were compared with 100 healthy controls. All subjects were submitted to three structured scales: 1) the World Health Organization Adult ADHD Self-Report Scale version 1.1 (ASRS); 2) the Hospital Anxiety and Depression Scale (HADS); and 3) the Adverse Events Profile (AEP). Dichotomic variables were analyzed through chi-square test and Fisher's exact test, as appropriate, and non-parametric variables were analyzed through the Mann-Whitney U test.

RESULTS

 Medians and interquartile ranges (IR) were: 1) ASRS: 26.00 (IR: 18 to 38) among PWE versus 17.00 (IR: 11 to 24) among controls, p < 0.001; 2) HADS: 14.00 (IR: 8 to 21) among PWE versus 11.00 (IR: 8 to 16) among controls, p = 0.007; 3) AEP: 3800 (IR: 31 to 49) among PWE versus 33.00 (IR: 23 to 43) among controls, p = 0.001.

CONCLUSION

 PWE showed a higher burden of symptoms of ADHD, depression, and anxiety when compared with controls, which replicates in the Brazilian population the findings of current literature that point toward a higher prevalence of such disorders among PWE.

Epilepsy and Encephalopathy

BACKGROUND

Epilepsy encompasses more than the predisposition to unprovoked seizures. In children, epileptic activity during (ictal) and between (interictal) seizures has the potential to disrupt normal brain development. The term "epileptic encephalopathy (EE)" refers to the concept that such abnormal activity may contribute to cognitive and behavioral impairments beyond that expected from the underlying cause of the epileptic activity.

METHODS

In this review, we survey the concept of EE across a diverse selection of syndromes to illustrate its broad applicability in pediatric epilepsy. We review experimental evidence that provides mechanistic insights into how epileptic activity has the potential to impact normal brain processes and the development of neural networks. We then discuss opportunities to improve developmental outcomes in epilepsy now and in the future.

RESULTS

Epileptic activity in the brain poses a threat to normal physiology and brain development.

CONCLUSION

Until we have treatments that reliably target and effectively treat the underlying causes of epilepsy, a major goal of management is to prevent epileptic activity from worsening developmental outcomes.

The association of structural connectome efficiency with cognition in children with epilepsy

OBJECTIVE

Cognitive impairment is common in children with epilepsy (CWE), but understanding the underlying pathological processes is challenging. We aimed to investigate the association of structural brain network organisation with cognition.

METHODS

This was a retrospective cohort study of CWE without structural brain abnormalities, comparing whole brain network characteristics between those with cognitive impairment and those with intact cognition. We created structural whole-brain connectomes from anatomical and diffusion tensor magnetic resonance imaging using the number of streamlines and tract-averaged fractional anisotropy. We assessed the differences in average path length and global network efficiency between children with cognitive impairment and those without,using multivariable analyses to account for possible clinical group differences.

RESULTS

Twenty-eight CWE and cognitive impairment had lower whole brain network global efficiency compared with 34 children with intact cognition (0.54, standard deviation (SD):0.003 vs. 0.56, SD:0.002, p < 0.001), which is equivalent to longer normalized network average path lengths (1.14, SD:0.05 vs. 1.10, SD:0.02, p = 0.003). In multivariable logistic regression cognitive impairment was not significantly associated with age of onset, duration of epilepsy, or number of antiseizure medications, but was independently associated with daily seizures (p = 0.04) and normalized average path length (p = 0.007).

CONCLUSIONS

Higher structural network average path length and lower global network efficiency may be imaging biomarkers of cognitive impairment in epilepsy. Understanding what leads to changes in structural connectivity could aid identification of modifiable risk factors for cognitive impairment. These findings are only applicable to the specific cohort studied, and further confirmation in other cohorts is required.

Brain language networks and cognitive outcomes in children with frontotemporal lobe epilepsy

Introduction

Pediatric frontal and temporal lobe epilepsies (FLE, TLE) have been associated with language impairments and structural and functional brain alterations. However, there is no clear consensus regarding the specific patterns of cerebral reorganization of language networks in these patients. The current study aims at characterizing the cerebral language networks in children with FLE or TLE, and the association between brain network characteristics and cognitive abilities.

Methods

Twenty (20) children with FLE or TLE aged between 6 and 18 years and 29 age- and sex-matched healthy controls underwent a neuropsychological evaluation and a simultaneous functional near-infrared spectroscopy and electroencephalography (fNIRS-EEG) recording at rest and during a receptive language task. EEG was used to identify potential subclinical seizures in patients. We removed these time intervals from the fNIRS signal to investigate language brain networks and not epileptogenic networks. Functional connectivity matrices on fNIRS oxy-hemoglobin concentration changes were computed using cross-correlations between all channels.

Results and discussion

Group comparisons of residual matrices (=individual task-based matrix minus individual resting-state matrix) revealed significantly reduced connectivity within the left and between hemispheres, increased connectivity within the right hemisphere and higher right hemispheric local efficiency for the epilepsy group compared to the control group. The epilepsy group had significantly lower cognitive performance in all domains compared to their healthy peers. Epilepsy patients' local network efficiency in the left hemisphere was negatively associated with the estimated IQ (p = 0.014), suggesting that brain reorganization in response to FLE and TLE does not allow for an optimal cognitive development.

Multi-dimensional influence of pediatric epilepsy on children and their families: A cross-sectional study

OBJECTIVE

In this study, we aimed to evaluate the effects of pediatric epilepsy on family burden, parental anxiety, depression states, and quality of life of both parents and children.

METHODS

The study was undertaken between March and December 2021 using an online questionnaire that included the Family Burden Scale of Disease, the 7-item Generalized Anxiety Disorder scale, the 9-item Patient Health Questionnaire, the WHO Quality of Life Scale (WHOQOL-BREF), and the PedsQL 4.0 Generic Core Scales (parent-proxy report).

RESULTS

A total of 288 parents of children aged 2-18 years were included. Overall, 94.8% of the participating families experienced high levels of disease burden, 67.0% of parents suffered from anxiety states, 57.0% suffered from depression states, and 56.2% of children with epilepsy suffered from comorbid neuropsychiatric symptoms. The mean WHOQOL-BREF score for parental quality of life was 53.7 ± 12.8, while the median PedsQL score for children's quality of life was 65.4 (49.6-81.7). Parental depression states contributed the most to family burden and parental quality of life, whereas comorbidities of epilepsy contributed the most to children's quality of life. Seizure frequency significantly influenced parental anxiety states, and family burden was the most significant predictor of parental depression states.

CONCLUSION

Heavy disease burden, anxiety states, and depression states are prevalent in families with children suffering from epilepsy, and most have a poor quality of life. There is a need for greater focus on the quality of life of this patient population and their caregivers, as well as increased resources to help combat anxiety, depression, and poor quality of life.

Psychosocial correlates of neurodevelopmental disabilities in 2- to 3-year-olds

RATIONALE

Canada's National Longitudinal Study of Children and Youth survey data provide insights into chronic health conditions in children. Children with neurodevelopmental disabilities (NDD) are at increased risk for adverse behavioral outcomes.

METHODS

We examined data from 3 cycles of Canada's National Longitudinal Survey of Children and Youth for the presence of epilepsy (Epi), cerebral palsy (CP), and intellectual disability (ID) in 2- to 3-year-olds. We then examined the relationship of NDD to composite measures of behavior: hyperactivity-inattention (HI), prosocial behaviors (PS), emotional disorder-anxiety (EA), physical aggression oppositional behavior (AO), and separation anxiety (SA).

RESULTS

There were 15 children with Epi, 25 with CP and 28 with ID in a sample of 10,879, which represented a population of 756,848 2- to 3-year-old Canadian children. Comparison of mean scores of the NDD groups and controls (Welch's ANOVA), indicated statistically significant differences in HI, PS, EA, and SA at the p < 0.001 level. Post hoc analysis showed significant intergroup differences. Children with epilepsy did not differ from controls on any of the behavioral measures. However, in comparison to controls, children with intellectual disability had higher EA and SA scores and lower PS scores, and those with cerebral palsy had lower PS scores.

CONCLUSIONS

Children with NDD show differences in behavioral outcomes at a very early age when compared with controls. Screening for these behaviors and early intervention programs may help avoid longer term psychiatric comorbidity associated with these disabilities.

Attention deficit hyperactivity disorder in patients with seizures: Functional seizures vs. epilepsy

BACKGROUND

We investigated the rates of positive screening for attention deficit-hyperactivity disorder (ADHD) in adults with seizures [i.e., focal epilepsy vs. idiopathic generalized epilepsy (IGE) vs. functional seizures (FS)]. We hypothesized that the rates of positive screening for ADHD are different between these three groups of patients.

METHODS

This was a cross sectional study. Patients, 19 to 55 years of age, with a diagnosis of IGE, focal epilepsy or FS were investigated at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, Shiraz, Iran, from September 2022 until January 2023 and during their follow-up visits. We used the validated Persian version of Adult ADHD Self-Report Scale (ASRS v1.1)15 to investigate and screen for ADHD in these patients.

RESULTS

Forty patients with focal epilepsy, 40 with IGE, and 40 with FS were included. Attention deficit-hyperactivity disorder (ADHD) screening was positive in 35% of patients with FS, in 30% of those with focal epilepsy (compared with FS, p = 0.633), and in 10% of patients with IGE (compared with FS, p = 0.007).

CONCLUSION

Adult patients with functional seizures and those with focal epilepsy are at a high risk of self-reporting experiences that could be characteristic of ADHD. Screening tools [e.g., Adult ADHD Self-Report Scale (ASRS v1.1)] are useful to help clinicians address seizure comorbidities such as ADHD. However, a clinical diagnosis of ADHD should be ascertained in a patient with positive screening.

Epilepsy phenotype and gene ontology analysis of the 129 genes in a large neurodevelopmental disorders cohort

Objective

Although pediatric epilepsy is an independent disease entity, it is often observed in pediatric neurodevelopmental disorders (NDDs) as a major or minor clinical feature, which might provide diagnostic clues. This study aimed to identify the clinical and genetic characteristics of patients with epilepsy in an NDD cohort and demonstrate the importance of genetic testing.

Methods

We retrospectively analyzed the detailed clinical differences of pediatric NDD patients with epilepsy according to their genetic etiology. Among 1,213 patients with NDDs, 477 were genetically diagnosed by exome sequencing, and 168 had epilepsy and causative variants in 129 genes. Causative genes were classified into two groups: (i) the "epilepsy-genes" group resulting in epilepsy as the main phenotype listed in OMIM, Epi25, and ClinGen (67 patients) and (ii) the "NDD-genes" group not included in the "epilepsy-genes" group (101 patients).

Results

Patients in the "epilepsy-genes" group started having seizures, often characterized by epilepsy syndrome, at a younger age. However, overall clinical features, including treatment responses and all neurologic manifestations, showed no significant differences between the two groups. Gene ontology analysis revealed the close interactions of epilepsy genes associated with ion channels and neurotransmitters.

Conclusion

We demonstrated a similar clinical presentation of different gene groups regarding biological/molecular processes in a large NDDs cohort with epilepsy. Phenotype-driven genetic analysis should cover a broad scope, and further studies are required to elucidate integrated pathomechanisms.

Impact of psychiatric comorbidities on the treatment of epilepsies in adults

INTRODUCTION

Epilepsy is often accompanied by psychiatric comorbidities and the management of epilepsy in these patients presents unique challenges due to the interplay between the underlying neurological condition and the psychiatric symptoms and the combined use of multiple medications.

AREAS COVERED

This paper aims to explore the complexities associated with managing epilepsy in the presence of psychiatric comorbidities, focusing on the impact of psychiatric disorders on epilepsy treatment strategies and the challenges posed by the simultaneous administration of multiple medications.

EXPERT OPINION

Patients with epilepsy and psychiatric comorbidities seem to present with a more severe form of epilepsy that is resistant to drug treatments and burdened by an increased morbidity and mortality. Whether prompt treatment of psychiatric disorders can influence the long-term prognosis of the epilepsy is still unclear as well as the role of specific treatment strategies, such as neuromodulation, in this group of patients. Clinical practice recommendations and guidelines will prompt the development of new models of integrated care to be implemented.

Patient and carer perspectives on the use of video consultations in the management of the ketogenic diet for epilepsy

BACKGROUND

The COVID-19 pandemic resulted in a significant change in the way healthcare was delivered worldwide. During this time, a survey of Ketogenic Dietitians Research Network (KDRN) members found that all respondents expected digital platforms for clinics and/or education to continue post-pandemic. As a follow-up to this, we surveyed views about video consultations (VCs) of patients and carers of those following the ketogenic diet for drug-resistant epilepsy.

METHODS

The Surveymonkey^TM survey was distributed on Matthews' Friends and KDRN social media platforms and emailed from five United Kingdom ketogenic diet centers to their patients/carers.

RESULTS

Forty eligible responses were received. More than half of the respondents (23, 57.5%) had attended a VC. Eighteen respondents (45%) would like to have VCs for most (categorized as approximately 75%) or all of their consultations. Half as many (9, 22.5%) would not like video consultations. The most common benefits selected were saving travel time (32, 80%), less stress of finding somewhere to park and not having to take time off work (22, 55% each). Twelve (30%) responded that VCs lessened environmental impact. The most common disadvantages selected were not being able to get blood tests/having to make a separate consultation for blood tests (22, 55% overall), not being able to get weight or height checked/having to make a separate consultation for this and it is less personal/preferring face-to-face (17, 42.5% each). Three-quarters (30 respondents) felt it would be very easy or easy to accurately weigh the patient when not attending an in-person consultation.

CONCLUSION

Our results suggest that many patients and carers would welcome the option of VCs as well as face-to-face consultations. Where possible and appropriate patients and their families should be offered both options. This is in line with the NHS Long-Term Plan and the NHS response to climate change.

'No one's ever said anything about sleep': A qualitative investigation into mothers' experiences of sleep in children with epilepsy

INTRODUCTION

Sleep problems in children with epilepsy (CWE) are common. However, little is known about parental experiences and feelings about managing sleep in their CWE. To provide the most appropriate services' provision, it is essential that the lived experience of parents of this patient group and the issues and problems that they face in managing their child's sleep is understood.

METHOD

In 2018, nine mothers of CWE (aged 5-15 years) were interviewed about their perceptions and experiences around their child's sleep, sleep problems and their management, the impact of sleep difficulties on the child and their family and available support.

RESULTS

Four themes were identified that represented the nature of the child's sleep problems, including settling and night-waking issues, parasomnias and child anxiety around sleep. Seven themes represented mothers' experiences of managing their child's sleep and any associated problems, including the longstanding challenging nature of child sleep issues, management strategies adopted, challenges related to managing sleep over time, the link between sleep and seizures, the negative impact of poor sleep on daytime functioning, role of antiseizure medication and maternal concerns about child sleep. One theme represented the perceived lack of information, help and support available.

CONCLUSIONS

Findings suggest there are unmet needs in supporting parents to deal with sleep, sleep problems and their management in CWE.

PATIENT OR PUBLIC CONTRIBUTION

This individual study was conducted under the umbrella of the CASTLE research programme (see https://castlestudy.org.uk/). Parents who have lived experience of parenting a child with epilepsy were co-applicants for the programme and were involved in the original conception, aims, design and funding application for the research programme (including the project reported in this paper) and advised on project design. Mothers of CWE who have lived experience of managing sleep and sleep problems in their child were participants who shared their experiences through the interviews, which formed the data of the current study.

Epilepsy and Attention Deficit Hyperactivity Disorder: Connection, Chance, and Challenges

Comorbidities are common in children with epilepsy, with nearly half of the patients having at least one comorbidity. Attention deficit hyperactivity disorder (ADHD) is a psychiatric disorder characterized by hyperactivity and inattentiveness level disproportional to the child’s developmental stage. The burden of ADHD in children with epilepsy is high and can adversely affect the patients’ clinical outcomes, psychosocial aspects, and quality of life. Several hypotheses were proposed to explain the high burden of ADHD in childhood epilepsy; the well-established bidirectional connection and shared genetic/non-genetic factors between epilepsy and comorbid ADHD largely rule out the possibility of a chance in this association. Stimulants are effective in children with comorbid ADHD, and the current body of evidence supports their safety within the approved dose. Nonetheless, safety data should be further studied in randomized, double-blinded, placebo-controlled trials. Comorbid ADHD is still under-recognized in clinical practice. Early identification and management of comorbid ADHD are crucial to optimize the prognosis and reduce the risk of adverse long-term neurodevelopmental outcomes. The identification of the shared genetic background of epilepsy and ADHD can open the gate for tailoring treatment options for these patients through precision medicine.

Knowledge about, and attitudes towards epilepsy among school staff: A UK-based survey

OBJECTIVE

To survey attitudes towards, and knowledge about, epilepsy among school staff in a defined geographical region in the United Kingdom.

METHODS

School staff (n = 160) from 18 schools (56% of eligible schools) where children with epilepsy were currently attending were surveyed. Surveys were developed in collaboration with educational professionals. Questions focussed on attitudes towards, and knowledge about, epilepsy. Factors associated with attitudes and knowledge were analyzed using multivariable logistic regression.

RESULTS

The majority of staff expressed positive attitudes towards the inclusion of children with epilepsy in school, although for most questions there was a significant minority who expressed less positive views. Only 30% of staff agreed that they would feel confident managing a child having a seizure whilst 42% of all staff would be concerned if they had to administer emergency medication. Regarding knowledge, half (50%) of respondents correctly indicated that a child who has a seizure should not always leave the classroom, whilst 54% knew that an ambulance should not always be called every time a child has a seizure. Regarding seizure semiology, almost all respondents (96%) answered 'yes' when asked if seizures could involve convulsions/limb jerking or whole-body convulsions. The vast majority (94%) also identified that seizures could involve 'staring blankly into space^'. From a list of eight medical/neurodevelopmental conditions, epilepsy was the condition staff ranked of most concern. Factors independently associated with more positive attitudes and better knowledge included working in a special school as opposed to a mainstream school, having previously witnessed a seizure, and having been in receipt of training on epilepsy (all p < 0.05). Most respondents expressed a desire for more training on seizure management and on the learning and behavioral aspects of epilepsy.

CONCLUSION

Whilst attitudes toward children with epilepsy are largely positive, epilepsy was the condition staff were most concerned about. Additionally, attitudes towards seizure management and administration of emergency medication in school are less positive, and knowledge of correct actions in the event of seizures in the classroom is deficient in nearly half of respondents. More positive attitudes and better knowledge were associated with previous experience of witnessing seizures, working in special schools, and having received epilepsy training. School staff in UK schools are likely to benefit from access to training on epilepsy in order to improve attitudes and increase knowledge and confidence towards supporting a child with epilepsy in their classroom.

Multimorbidity in People with Epilepsy

Multimorbidity is an emerging priority in healthcare due to associations with the ageing population, frailty, polypharmacy, health and social care demands. It affects 60-70% of adults and 80% of children with epilepsy. Neurodevelopmental conditions are commonly seen in children with epilepsy, while cancer, cardiovascular and neurodegenerative conditions often afflict older people with epilepsy. Mental health problems are common across the lifespan. Genetic, environmental, social and lifestyle factors contribute to multimorbidity and its consequences. Multimorbid people with epilepsy (PWE) are at higher risk of depression and suicide, premature death, suffer lower health-related quality of life, and require more hospital admissions and health care costs. The best management of multimorbid PWE requires a paradigm shift from the traditional single disease-single comorbidity approach and a refocus on a person-centred approach. Improvements in health care must be informed by assessing the burden of multimorbidity associated with epilepsy, delineating disease clusters, and measuring the effects on health outcomes.

Traditional and Innovative Anti-seizure Medications Targeting Key Physiopathological Mechanisms: Focus on Neurodevelopment and Neurodegeneration

Despite the wide range of compounds currently available to treat epilepsy, there is still no drug that directly tackles the physiopathological mechanisms underlying its development. Indeed, antiseizure medications attempt to prevent seizures but are inefficacious in counteracting or rescuing the physiopathological phenomena that underlie their onset and recurrence, and hence do not cure epilepsy. Classically, the altered excitation/inhibition balance is postulated as the mechanism underlying epileptogenesis and seizure generation. This oversimplification, however, does not account for deficits in homeostatic plasticity resulting from either insufficient or excessive compensatory mechanisms in response to a change in network activity. In this respect, both neurodevelopmental epilepsies and those associated with neurodegeneration may share common underlying mechanisms that still need to be fully elucidated. The understanding of these molecular mechanisms shed light on the identification of new classes of drugs able not only to suppress seizures, but also to present potential antiepileptogenic effects or "disease-modifying" properties.

Characteristics and Challenges of Epilepsy in Children with Cerebral Palsy-A Population-Based Study

The aim of this population-based study was to describe the prevalence and characteristics of epilepsy in children with cerebral palsy (CP), focusing on antiseizure medication (ASM) and seizure outcome. Findings were related to CP type, gross motor function and associated impairments. Data on all 140 children with CP born in 2003-2006 were taken from the CP register of Western Sweden. Medical records were reviewed at ages 9-12 and 13-16 years. In total 43% had a diagnosis of epilepsy. Epilepsy was more common in children with dyskinetic CP, who more often had a history of infantile spasms, continuous spike-and-wave during sleep and status epilepticus. Neonatal seizures, severe intellectual disability, severe motor disability and autism were associated with a higher risk of epilepsy. Many children were on polytherapy, and valproate was frequently used, even in girls. At age 13-16 years, 45% of the children with epilepsy were seizure free for at least one year. Onset after 2 years of age, female sex and white matter injury were associated with good seizure outcome. Despite the risk of relapse, reduction or discontinuation of ASM could be an option in selected cases. It is important to optimize ASM and to consider the possibility of epilepsy surgery.

Perceived impact of epilepsy on sleep: Views of children with epilepsy, parents and school staff

OBJECTIVE

To gain an understanding of the views of school-aged children with epilepsy, their parents, and school staff regarding the impact of epilepsy on sleep.

METHODS

As part of the What I Need in School (WINS) study, school-aged children (n = 18) with 'active epilepsy' (taking Anti-Seizure Medications, ASMs, for epilepsy), their parents (n = 68) and school staff (n = 56) were interviewed or completed bespoke questionnaires. Questions focussed on the potential impact of epilepsy on the child's sleep or tiredness in school and the potential impact of sleep/tiredness on learning and behavior.

RESULTS

Fifty-six percent of children believed that epilepsy affects their sleep while 65% of parents believed that their child had more difficulties with sleep than other children of their age. Seventy-eight percent of parents believed that their child's difficulties were due to epilepsy and 95% believed that their child's difficulties impacted their learning and behavior. Fifty-four percent of school staff believed that the child with epilepsy they supported was more tired/fatigued than their peers, and 86% of school staff believed that the child's increased tiredness affected their learning/behavior. Parents of children with intellectual disabilitiy were significantly more likely to indicate that they felt that their child had more sleep difficulties than other children (p = 0.016). Regarding the impact on their sleep, participating children felt that epilepsy contributed to difficulties in falling and staying asleep and daytime tiredness. Their parents reported a range of potential sleep difficulties and potential impacts on the child's learning and behavior. Parental reported difficulties included daytime tiredness, difficulty falling and staying asleep, and the impact of nocturnal seizures. In terms of impact, parents felt that sleep difficulties impacted negatively cognition and emotional-behavioral functioning. Additionally, parents reported that ASMs and medication for ADHD can contribute to sleep difficulties. School staff felt that many of the children appeared tired/fatigued during the day and this could lead to less engagement with classroom activities, impact attention and processing speed negatively, and contribute to behavioral and emotional difficulties.

CONCLUSION

The majority of children and parents who responded believed that epilepsy affects the child's sleep. Most parents and school staff also believed that the child's sleep difficulties/excess tiredness were due to the child's epilepsy and that the difficulties significantly impacted the child's learning and behavior. There is a need to better understand the role epilepsy plays in sleep difficulties and associated learning and behavioral impairments. There is also a need to develop interventions to reduce the subsequent impact on child learning and behavior.

Supporting Attention in Children with Epilepsy (SPACE): Pilot of a psychoeducational intervention

PURPOSE

Children with epilepsy are at high risk for impairing symptoms of attention deficit hyperactivity disorder (ADHD), especially difficulties with attention. There is limited evidence regarding the use of psychological interventions for children with epilepsy and attention difficulties. We developed and piloted a novel psychoeducational intervention -Supporting Attention in Children with Epilepsy (SPACE).

METHODS

Eligible children with epilepsy (8-13 years) and difficulties with attention underwent a comprehensive psychological assessment and took part in a single-arm trial of the SPACE intervention. The first three sessions of SPACE took place in groups of 3-5 children and two psychologists. The final three sessions involved one psychologist meeting the child and parent(s). The child's teacher joined for one of the final three sessions. The first group of participants participated in the intervention in person. Subsequent groups took part online due to COVID-19-related restrictions. Measures of ADHD -inattention symptoms (parent and teacher), executive functioning (child, parent, and teacher), and epilepsy-specific and general Health-Related Quality of Life (HRQOL) (child and parent) were administered before and three months after completing the intervention.

RESULTS

Twenty-seven children with epilepsy expressed an interest in participating. Sixteen children met eligibility criteria and participated in a single-arm pilot of the intervention. All 16 participants completed the intervention. Pre- and post-intervention data were available for 15 of the 16 children. Improvement in function was noted on all measures and reached statistical significance for child ratings of executive functioning (p = 0.030) and HRQOL (p = 0.043), and parent-rated child HRQOL (p < 0.001). Qualitative feedback regarding content and acceptability was positive.

CONCLUSION

A psychoeducational intervention for children with epilepsy and difficulties with attention can lead to improved executive functioning and HRQOL. Such an intervention may be a useful first-line intervention for children with epilepsy at risk for or diagnosed with ADHD and/or be used in combination with pharmacological treatment with children with epilepsy and ADHD. However, more robustly designed studies are needed.

Strategies and tools to aid the transition between paediatric and adult health services for young adults with neurodevelopmental disorders: a scoping review protocol

INTRODUCTION

The transition from paediatric to adult healthcare comes with risk and vulnerability for young adults with neurodevelopmental disorders and their carers. Deficits in health, social and disability systems and the fragmentation of services exacerbate problems during the transition period, leaving young people and their carers feeling disconnected with existing services. With advances in healthcare, the number of young adults with neurodevelopmental disorders requiring transition services is increasing. This scoping review aims to summarise the strategies and tools that help ease the transition to adult services for young adults with neurodevelopmental disorders.

METHODS AND ANALYSIS

Systematic searches of MEDLINE, EMBASE and PsychInfo on the OVID platform were performed on 28/05/2022. Studies that describe tools or strategies designed to ease the transition from child-centred to adult-orientated healthcare for young adults with neurodevelopmental disorders will be included. Two authors will independently review titles, abstracts and full-text articles against the inclusion criteria to determine eligibility. Data will be extracted and synthesised using descriptive stats and thematic analysis. The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines will be followed.

CONCLUSION

This scoping review will synthesise the published literature describing strategies and tools to improve the transition of young adults with neurodevelopmental disorders to adult services. The findings of the review may inform areas of future research to improve care for all involved in the transition process.

ETHICS AND DISSEMINATION

This review will include published data; as such, ethics approval is not required. We will publish our findings in an open-access, peer-reviewed journal and summarise the results for dissemination to the wider community of clinicians, allied healthcare professionals, teaching professionals, policymakers, non-governmental organisations, impacted youth and parents.

Loss of Rai1 enhances hippocampal excitability and epileptogenesis in mouse models of Smith-Magenis syndrome

Smith–Magenis syndrome (SMS) is a neurodevelopmental disorder associated with autism and epileptic seizures. SMS is caused by losing one copy of the gene encoding retinoic acid induced 1 (RAI1), a ubiquitously expressed transcriptional regulator. To pinpoint brain regions and cell types contributing to neuronal hyperexcitability in SMS, we combined electrophysiology and three-dimensional imaging of Fos expression in the intact mouse brain. We found that Rai1-deficient hippocampal dentate gyrus granule cells (dGCs) show increased intrinsic excitability and enhanced glutamatergic synaptic transmission. Our findings indicate that Rai1 safeguards the hippocampal network from hyperexcitability and could help explain abnormal brain activity in SMS.

Hyperexcitability of brain circuits is a common feature of autism spectrum disorders (ASDs). Genetic deletion of a chromatin-binding protein, retinoic acid induced 1 (RAI1), causes Smith–Magenis syndrome (SMS). SMS is a syndromic ASD associated with intellectual disability, autistic features, maladaptive behaviors, overt seizures, and abnormal electroencephalogram (EEG) patterns. The molecular and neural mechanisms underlying abnormal brain activity in SMS remain unclear. Here we show that panneural Rai1 deletions in mice result in increased seizure susceptibility and prolonged hippocampal seizure duration in vivo and increased dentate gyrus population spikes ex vivo. Brain-wide mapping of neuronal activity pinpointed selective cell types within the limbic system, including the hippocampal dentate gyrus granule cells (dGCs) that are hyperactivated by chemoconvulsant administration or sensory experience in Rai1-deficient brains. Deletion of Rai1 from glutamatergic neurons, but not from gamma-aminobutyric acidergic (GABAergic) neurons, was responsible for increased seizure susceptibility. Deleting Rai1 from the Emx1^Cre-lineage glutamatergic neurons resulted in abnormal dGC properties, including increased excitatory synaptic transmission and increased intrinsic excitability. Our work uncovers the mechanism of neuronal hyperexcitability in SMS by identifying Rai1 as a negative regulator of dGC intrinsic and synaptic excitability.

Impact of epilepsy on learning and behaviour and needed supports: Views of children, parents and school staff

BACKGROUND

There is limited data on the views of young people with epilepsy, their parents and school staff regarding the impact of epilepsy on learning and behaviour in school. The purpose of the study was to gain an understanding of the impact of epilepsy on learning and behaviour and needed supports according to children with epilepsy, their parents and supporting school staff.

METHODS

School-aged children (n = 20) with 'active epilepsy' (taking anti-seizure Medications (ASMs) for epilepsy), their parents (n = 68) and school staff (n = 56) were interviewed or completed surveys. The quantitative data was analysed using descriptive statistics and responses were compared for children attending mainstream and special schools using chi-square analyses. The answers to open questions were answered using thematic analyses.

RESULTS

The majority (53%) of children with epilepsy felt that epilepsy affected their learning including aspects such as memory, attention and concentration but also physical and emotional wellbeing including increased tiredness and lowered self-confidence. In addition, children brought up possible negative aspects of taking ASMs including increased irritability and emotional reactivity. The children also mentioned that epilepsy in school was associated with stigma and restrictions. The majority (85%) of parents agreed that epilepsy affects the child's learning/behaviour while more staff agreed that epilepsy affects learning (61%) than behaviour (45%). Most parents agreed that that their child's school provided the appropriate resources to support their child's learning (79%) and 72% agreed that they were satisfied overall with the support their child received at school. However, parents of children attending special schools were more likely to agree that the child's school provided appropriate resources to support their child's learning (p = 0.034) and be satisfied with the support their child received in school (p = 0.02), than parents of children attending mainstream schools. With respect to current or desired supports, analysis of the children's responses indicated that they want access to supportive environments outside the classroom, accommodations in tests/exams and increased support from trusted adults. Parent responses included approaches that promote child wellbeing, environmental accommodations, a high ratio of adult support and a consideration of the child's communication needs. Staff views regarding optimal strategies included a high level of adult support for the child, environmental accommodations, use of multimodal learning, adapting communication and approaches that promote psychological wellbeing.

CONCLUSIONS

The majority of children perceived that epilepsy affected their learning and behaviour in school including leading to specific learning difficulties, but also negative impacts on emotional and physical wellbeing. Levels of parental satisfaction with supports were significantly higher in special schools compared with mainstream schools. Children, parents and staff highlighted a number of supports which they felt can support the child with epilepsy's learning but also emotional wellbeing.

Behavioral health screening in pediatric epilepsy: Which measures commonly used in the United States are 'good enough'?

PURPOSE

To improve evidence-based implementation of behavioral health screening measures in pediatric epilepsy care, guidance is needed in the selection and interpretation of evidence-based screening measures. Therefore, the goals of this project were to (1) evaluate the clinical utility and psychometric properties of screening instruments frequently used in the United States (US) for anxiety, depression, and behavior problems in youth with epilepsy (YWE), and (2) provide guidance around selection and interpretation of these behavioral health screening measures.

METHOD

The critique was conducted in three phases: (1) identification of articles based on search criteria; (2) full review of articles for eligibility assessment; (3) evaluation of screening measures and organization into Tiers. Nine behavioral health measures frequently used to screen for anxiety, depression, and disruptive behaviors in the US were selected for evaluation. PubMed, CINAHL, Medline, and APA databases were searched using the following search terms: [target area] + [screening measure] + epilepsy + children [youth], [adolescents]. Inclusion/exclusion criteria for articles were as follows: (1) focused on YWE, (2) written in English, and (3) conducted in the US. Once articles were selected, Hunsley and Mash's criteria were used to evaluate and categorize the screening measures' psychometric properties, which have clear relevance to clinical practice. Measures were also classified into three tiers by the level of validation according to established evidence-based criteria.

RESULTS

Forty-one unique papers were identified through the literature search and assessed as eligible. Evaluation of screening measures revealed only two psychometrically sound measures that met criteria for Tier 1, the NDDI-E-Y and the Pediatric NeuroQoL-Depression, both depression screening measures. Several additional depression screening measures met criteria for Tier 2 (CDI-2, BASC-2-Depression Scale, and CBCL Withdrawn/Depressed Scale). Anxiety screening measures have not been validated in pediatric epilepsy and thus only met the criteria for Tier 2 (BASC-2 Anxiety Scale, CBCL DSM-IV Oriented Anxiety Problems Scale, MASC). Similarly for disruptive behaviors, two measures met Tier 2 criteria (BASC-2 Externalizing Problems Index, CBCL Externalizing Problems Index).

CONCLUSION

Strides have been made in the validation of behavioral health screening measures for YWE; however, continued research in this area is necessary to validate existing psychometrically sound measures and to develop and evaluate epilepsy-specific measures in the pediatric epilepsy population.

Interictal discharges delay target-directed eye movements and impair attentional set-shifting in children with epilepsy

OBJECTIVES

The theory of transient cognitive impairment in epilepsy posits that lapses in attention result from ephemeral disruption of attentional circuitry by interictal events. Eye movements are intimately associated with human attention and can be monitored in real -time using eye-tracking technologies. Here, we sought to characterize the associations between interictal discharges (IEDs), gaze, and attentional behaviour in children with epilepsy.

METHODS

Eleven consecutive children undergoing invasive monitoring with stereotactic electrodes for localization-related epilepsy performed an attentional set-shifting task while tandem intracranial electroencephalographic signals and eye-tracking data were recorded. Using an established algorithm, IEDs were detected across all intracranial electrodes on a trial-by-trial basis. Hierarchical mixed-effects modelling was performed to delineate associations between trial reaction time (RT), eye movements, and IEDs.

RESULTS

Hierarchical mixed-effects modelling revealed that both the presence of an IED (β±SE=72.74±24.21ms, p=0.003) and the frequency of epileptiform events (β±SE=67.54±17.30ms, p<0.001) were associated with prolonged RT on the attentional set-shifting task. IED occurrence at the time of stimulus presentation was associated with delays in gaze initiation toward the visual targets (p=0.017).

SIGNIFICANCE

The occurrence of epileptiform activity in close temporal association with stimulus presentation is associated with delays in target-directed gaze and prolonged response time, hallmarks of momentary lapses in attention. These findings provide novel insights into the mechanisms of transient impairments in children and support the use of visual tracking as a correlate of higher-order attentional behaviour.

Parents of children with epilepsy: Characteristics associated with high and low levels of health literacy

Parents of children with epilepsy play a key role in the management of their child's condition. Their level of health literacy (HL), which refers to their ability to seek, understand, assess, remember, and utilize health information, is essential for handling the child optimally. The aim of this study was to investigate characteristics associated with high and low levels of different dimensions of HL in parents. HL was assessed with the multidimensional Health Literacy Questionnaire (parents' version) and the electronic Health Literacy Scale, using data from a cohort of 254 parents of children <12 years. Bivariate correlation and multiple hierarchal linear regression (STATA version 16 SE) were used to investigate variables associated with HL. Self-efficacy (St. β = 0.14-0.34) was the only variable that predicted higher scores on every HL scale. Being older than 35 years (St. β = 0.18-0.21), level of education (St. β = 0.16-0.27), and the child having a coordinator of services (St. β = 0.16-0.28) were associated with higher scores, while sick leave due to the child's epilepsy (St. β = -0.13 to -0.16), child comorbidities (St. β = -0.15 to -0.19), and higher levels of mental distress (St. β = -0.13 to -0.19) were associated with lower scores in several of the different HL dimensions. A total of 44.8% of the parents scored over the cutoff (≥1.85) predicting a mental disorder on the Hopkins symptom checklist. This is the first study to investigate multidimensional parental HL in a childhood epilepsy context. Our results highlight the need to investigate multiple variables, especially mental distress, to determine characteristics that may predict low parental HL. Further qualitative studies are needed to explore the underlying reasons for the parents' HL scores and to develop inventions tailored to meet different HL needs.

Neuropsychiatric and Cognitive Comorbidities in Epilepsy

PURPOSE OF REVIEW

This article discusses psychiatric and cognitive comorbidities of epilepsy over the lifespan and illustrates opportunities to improve the quality of care of children and adults with epilepsy.

RECENT FINDINGS

One in 3 people with epilepsy have a lifetime history of psychiatric disorders, and they represent an important prognostic marker of epilepsy. Contributors are diverse and display a complex relationship. Cognitive comorbidities are also common among those living with epilepsy and are increasingly recognized as a reflection of changes to underlying brain networks. Among the cognitive comorbidities, intellectual disability and dementia are common and can complicate the diagnostic process when cognitive and/or behavioral features resemble seizures.

SUMMARY

Comorbidities require consideration from the first point of contact with a patient because they can determine the presentation of symptoms, responsiveness to treatment, and the patient's day-to-day functioning and quality of life. In epilepsy, psychiatric and cognitive comorbidities may prove a greater source of disability for the patient and family than the seizures themselves, and in the case of essential comorbidities, they are regarded as core to the disorder in terms of etiology, diagnosis, and treatment.

Neurological consultation with an autistic patient

Autism is a neurodevelopmental condition with a very heterogeneous presentation. Autistic people are more likely to have unmet healthcare needs, making it essential that healthcare professionals are 'autism-aware'. In this article, we provide an overview of how autism presents and use case studies to illustrate how a neurological consultation in an outpatient clinic environment could prove challenging for a autistic person. We suggest how to improve communication with autistic patients in clinic and highlight the importance of a patient-centred and flexible approach.

Broadband-NIRS System Identifies Epileptic Focus in a Child with Focal Cortical Dysplasia—A Case Study

Epileptic seizures are transiently occurring symptoms due to abnormal excessive or synchronous neuronal activity in the brain. Previous functional near-infrared spectroscopy (fNIRS) studies during seizures have focused in only monitoring the brain oxygenation and haemodynamic changes. However, few tools are available to measure actual cellular metabolism during seizures, especially at the bedside. Here we use an in-house developed multichannel broadband NIRS (or bNIRS) system, that, alongside the changes in oxy-, deoxy- haemoglobin concentration (HbO₂, HHb), also quantifies the changes in oxidised cytochrome-c-oxidase Δ(oxCCO), a marker of cellular oxygen metabolism, simultaneously over 16 different brain locations. We used bNIRS to measure metabolic activity alongside brain tissue haemodynamics/oxygenation during 17 epileptic seizures at the bedside of a 3-year-old girl with seizures due to an extensive malformation of cortical development in the left posterior quadrant. Simultaneously Video-EEG data was recorded from 12 channels. Whilst we did observe the expected increase in brain tissue oxygenation (HbD) during seizures, it was almost diminished in the area of the focal cortical dysplasia. Furthermore, in the area of seizure origination (epileptic focus) ΔoxCCO decreased significantly at the time of seizure generalization when compared to the mean change in all other channels. We hypothesize that this indicates an incapacity to sustain and increase brain tissue metabolism during seizures in the region of the epileptic focus.

Behavioral phenotypes of pediatric temporal lobe epilepsy

OBJECTIVE

A broad spectrum of emotional-behavioral problems have been reported in pediatric temporal lobe epilepsy (TLE), but with considerable variability in their presence and nature of expression, which hampers precise identification and treatment. The present study aimed to empirically identify latent patterns or behavioral phenotypes and their correlates.

METHODS

Data included parental ratings of emotional-behavioral status on the Behavior Assessment System for Children, 2nd Edition (BASC-2) of 81 children (mean age = 11.79, standard deviation [SD] = 3.93) with TLE. The nine clinical subscales were subjected to unsupervised machine learning to identify behavioral subgroups. To explore concurrent validity and the underlying composition of the identified clusters, we examined demographic factors, seizure characteristics, psychosocial factors, neuropsychological performance, psychiatric status, and health-related quality of life (HRQoL).

RESULTS

Three behavioral phenotypes were identified, which included no behavioral concerns (Cluster 1, 43% of sample), externalizing problems (Cluster 2, 41% of sample), and internalizing problems (Cluster 3, 16% of sample). Behavioral phenotypes were characterized by important differences across clinical seizure variables, psychosocial/familial factors, everyday executive functioning, and HRQoL. Cluster 2 was associated with younger child age, lower maternal education, and higher rate of single-parent households. Cluster 3 was associated with older age at epilepsy onset and higher rates of hippocampal sclerosis and parental psychiatric history. Both Cluster 2 and 3 demonstrated elevated family stress. Concurrent validity was demonstrated through the association of psychiatric (i.e., rate of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) disorders and psychotropic medication) and parent-rated HRQoL variables.

SIGNIFICANCE

Youth with TLE present with three distinct behavioral phenotypes that correspond with important clinical and sociodemographic markers. The current findings demonstrate the variability of behavioral presentations in youth with TLE and provide a preliminary framework for screening and targeting intervention to enhance support for youth with TLE and their families.

The Impact of Glutamatergic Synapse Dysfunction in the Corticothalamocortical Network on Absence Seizure Generation

Childhood absence epilepsy (CAE) is the most common pediatric epilepsy affecting 10–18% of all children with epilepsy. It is genetic in origin and the result of dysfunction within the corticothalamocortical (CTC) circuitry. Network dysfunction may arise from multifactorial mechanisms in patients from different genetic backgrounds and thus account for the variability in patient response to currently available anti-epileptic drugs; 30% of children with absence seizures are pharmaco-resistant. This review considers the impact of deficits in AMPA receptor-mediated excitation of feed-forward inhibition (FFI) in the CTC, on absence seizure generation. AMPA receptors are glutamate activated ion channels and are responsible for most of the fast excitatory synaptic transmission throughout the CNS. In the stargazer mouse model of absence epilepsy, the genetic mutation is in stargazin, a transmembrane AMPA receptor trafficking protein (TARP). This leads to a defect in AMPA receptor insertion into synapses in parvalbumin-containing (PV+) inhibitory interneurons in the somatosensory cortex and thalamus. Mutation in the Gria4 gene, which encodes for the AMPA receptor subunit GluA4, the predominant AMPA receptor subunit in cortical and thalamic PV + interneurons, also leads to absence seizures. This review explores the impact of glutamatergic synapse dysfunction in the CTC network on absence seizure generation. It also discusses the cellular and molecular mechanisms involved in the pathogenesis of childhood absence epilepsy.

A Retrospective Analysis of Psychiatric Presurgical Evaluation of Children and Adolescents Evaluated for Epilepsy Surgery in a Comprehensive Epilepsy Care Unit of Mumbai

Background  Epilepsy being one of the most prevalent neurological diseases in children is associated with psychopathology and academic concerns. Epilepsy surgery is considered for refractory epilepsy at some centers in India and hence this study was undertaken to find out prevalence and type of psychopathology in children and adolescents with refractory epilepsy before epilepsy surgery. Methods  All data were analyzed from the records of patients undergoing preepilepsy surgery protocol workup in comprehensive center of epilepsy care at a general municipal hospital in Mumbai. A record of 150 children and adolescents in the age group of 3 to 18 years over a period of 10 years was taken and all details of demographics, epilepsy, and psychopathology were recorded. Results  The mean age for our sample was 11.4 ± 3.4 years and a male preponderance was seen. Majority (80%) of the children were pursuing education. The duration of seizure disorder was approximately 4.41 + 2.36 years and complex partial seizures were seen commonly in 50% of the children. Both magnetic resonance imaging (MRI) and video electroencephalography (VEEG) findings revealed right sided lateralization followed by left in majority of the patients. Psychopathology was seen in 70 (46%) patients with mental retardation, hyperkinetic disorders affecting attention and activity and oppositional defiant disorder, and unspecified mental disorder due to underlying brain damage being the type of International Classification of Disease-10th Revision (ICD-10) disorders seen. Patients with psychopathology showed a left-sided predominance on their MRI and VEEG findings for laterality of the epileptogenic focus as compared with right side. Conclusion  Refractory seizures and associated psychopathology impact family life, friendships, and academics and worsen prognosis and quality of life. Screening for psychopathology in children with epilepsy would therefore lead to better outcomes especially prior to epilepsy surgery.

Effects of Stable Vagus Nerve Stimulation Efficacy on Autistic Behaviors in Ten Pediatric Patients With Drug Resistant Epilepsy: An Observational Study

Vagus nerve stimulation (VNS) is a safe and effective therapy for pediatric patients with drug-resistant epilepsy (DRE). However, in children with DRE, the effects of VNS on autistic behaviors remain controversial. We retrospectively collected data from 10 children with DRE who underwent VNS implantation and regular parameter regulation in three pediatric epilepsy centers, and completed the behavioral assessments, including the autistic behavior checklist and the child behavior checklist, at follow-ups 1 (mean 2.16 years) and 2 (mean 2.98 years). The 10 children maintained stable seizure control between the two follow-ups. Their autistic behaviors, especially in language, social and self-help, were reduced at follow-up 2 compared to follow-up 1 (p = 0.01, p = 0.01, respectively). Moreover, these improvements were not associated with their seizure control, whether it was positive or negative. These results suggested that the VNS had a positive effect on autistic behaviors, which provided a preliminary clinical basis that VNS may benefit to younger children with DRE comorbidity autism spectrum disorder (ASD).

Spectral changes following resective epilepsy surgery and neurocognitive function in children with epilepsy

Decelerated resting cortical oscillations, high-frequency activity, and enhanced cross-frequency interactions are features of focal epilepsy. The association between electrophysiological signal properties and neurocognitive function, particularly following resective surgery, is, however, unclear. In the current report, we studied intraoperative recordings from intracranial electrodes implanted in seven children with focal epilepsy and analyzed the spectral dynamics both before and after surgical resection of the hypothesized seizure focus. The associations between electrophysiological spectral signatures and each child's neurocognitive profiles were characterized using a partial least squares analysis. We find that extent of spectral alteration at the periphery of surgical resection, as indexed by slowed resting frequency and its acceleration following surgery, is associated with baseline cognitive deficits in children. The current report provides evidence supporting the relationship between altered spectral properties in focal epilepsy and neuropsychological deficits in children. In particular, these findings suggest a critical role of disrupted thalamocortical rhythms, which are believed to underlie the spectral alterations we describe, in both epileptogenicity and neurocognitive function.NEW & NOTEWORTHY Spectral alterations marked by decelerated resting oscillations and ectopic high-frequency activity have been noted in focal epilepsy. We leveraged intraoperative recordings from chronically implanted electrodes pre- and postresection to understand the association between these electrophysiological phenomena and neuropsychological function. We find that the extent of spectral alteration, indexed by slowed resting frequency and its acceleration following resection, is associated with baseline cognitive deficits. These findings provide novel insights into neurocognitive impairments in focal epilepsy.

Neurodevelopmental and psychiatric comorbidities negatively affect outcome in children with unprovoked seizures-A non-systematic review

Children with epilepsy have at least one comorbidity in 80% of cases. This unstructured review provides insights into the most common comorbidities, their effects on seizure prognosis and treatment. We also review the epilepsy terminology and classifications. Neurodevelopmental and psychiatric comorbidities were common in children with seizures and had a negative effect on quality of life, and seizure freedom. Children with seizures were treated with drugs used for attention deficit hyperactivity disorder (ADHD), depression or psychosis, more often than the general population but less often than prevalence rates would suggested. CONCLUSION: Multidisciplinary teams should assess comorbidities in children with epilepsy to improve their care and outcomes.
