RESUMEN

AIM: Sturge-Weber syndrome (SWS) is a rare neurocutaneous syndrome, frequently associated with pharmaco-resistant, early-onset epilepsy. Optimal seizure control is paramount to maximize neurodevelopment. METHOD: A single-centre case series of 49 infants explored early SWS care. Ninety-two per cent of children developed seizures aged 0 to 3 years; 55% of cases were before diagnostic magnetic resonance imaging (MRI) or tertiary referral. Delay in SWS diagnosis affected 31% of infants because of a lack of gadolinium enhancement for initial MRI. First seizures were frequently prolonged, with phenytoin administration necessary in 46%. Presymptomatic antiseizure medication prophylaxis (n = 8/49) decreased seizure burden. No patients on antiseizure medication prophylaxis suffered status epilepticus for longer than 30 minutes, and half of them (n = 4) had not developed seizures at last follow-up (aged 2-10 years). RESULTS: A parental survey enabled further service evaluation. Eighty-three per cent of parents considered local clinicians' understanding of SWS inadequate: 61% felt insufficiently informed about SWS and 81% received no epilepsy education before seizures. INTERPRETATION: To overcome the identified shortfalls, guidelines towards improving and standardizing SWS management are proposed.

RESUMEN

Mosaic mutations in genes GNAQ or GNA11 lead to a spectrum of diseases including Sturge-Weber syndrome and phakomatosis pigmentovascularis with dermal melanocytosis. The pathognomonic finding of localized "tramlining" on plain skull radiography, representing medium-sized neurovascular calcification and associated with postnatal neurological deterioration, led us to study calcium metabolism in a cohort of 42 children. In this study, we find that 74% of patients had at least one abnormal measurement of calcium metabolism, the commonest being moderately low serum ionized calcium (41%) or high parathyroid hormone (17%). Lower levels of ionized calcium even within the normal range were significantly associated with seizures, and with specific antiepileptics despite normal vitamin D levels. Successive measurements documented substantial intrapersonal fluctuation in indices over time, and DEXA scans were normal in patients with hypocalcemia. Neurohistology from epilepsy surgery in five patients revealed not only intravascular, but perivascular and intraparenchymal mineral deposition and intraparenchymal microvascular disease in addition to previously reported findings. Neuroradiology review clearly demonstrated progressive calcium deposition in individuals over time. These findings and those of the adjoining paper suggest that calcium deposition in the brain of patients with GNAQ/GNA11 mosaicism may not be a nonspecific sign of damage as was previously thought, but may instead reflect the central postnatal pathological process in this disease spectrum.

RESUMEN

Objectives: During the COVID-19 pandemic, healthcare resources including staff were diverted from paediatric services to support COVID-positive adult patients. Hospital visiting restrictions and reductions in face-to-face paediatric care were also enforced. We investigated the impact of service changes during the first wave of the pandemic on children and young people (CYP), to inform recommendations for maintaining their care during future pandemics. Design: A multi-centre service evaluation was performed through a survey of consultant paediatricians working within the North Thames Paediatric Network, a group of paediatric services in London. We investigated six areas: redeployment, visiting restrictions, patient safety, vulnerable children, virtual care and ethical issues. Results: Survey responses were received from 47 paediatricians across six National Health Service Trusts. Children's right to health was largely believed to be compromised by the prioritisation of adults during the pandemic (81%; n = 33). Sub-optimal paediatric care due to redeployment (61%; n = 28) and the impact of visiting restrictions on CYP's mental health (79%; n = 37) were reported. Decreased hospital attendances of CYP were associated with parental fear of COVID-19 infection-risks (96%; n = 45) and government 'stay at home' advice (89%; n = 42). Reductions in face-to-face care were noted to have disadvantaged those with complex needs, disabilities and safeguarding concerns. Conclusion: Consultant paediatricians perceived that paediatric care was compromised during the first wave of the pandemic, resulting in harm to children. This harm must be minimised in subsequent pandemics. Recommendations for future practice which were developed from our findings are provided, including maintaining face-to-face care for vulnerable children.

RESUMEN

A systematic retrospective case note review was undertaken to investigate autism diagnostic factors in 124 individuals with Sturge-Weber syndrome (SWS). Social Responsiveness Scale questionnaires were then analysed to explore the severity and profile of autism characteristics in 70 participants. Thirty-two to forty percent of participants had a clinical diagnosis of autism and half of those without a diagnosis showed significant social communication difficulties. Children had a relative strength in social awareness and social motivation, which are typically much reduced in people with autism. This finding may explain why, to date, the diagnosis has often been overlooked in this population. The research therefore suggests that children with Sturge-Weber should be screened to identify social communications difficulties and provided with timely support.

RESUMEN

INTRODUCTION: This study of children with Sturge-Weber syndrome (SWS) profiled neurological presentations; compared patients with (+) and without (-) port-wine stain (PWS); and determined risk factors for intellectual and language impairments. METHODS: A retrospective case note review was conducted at a national centre. RESULTS: This cohort (n = 140, male 72, median follow up 114 months) showed sex parity. Intellectual disability ("ID": IQ ≤ 70) affected half (66), being severe (IQ ≤ 40) in two-fifths (27) with ID. Language disorder (core score≤70) affected half (57). Neurological presentations were: status epilepticus 57% (80), hemiplegia 58% (81), headaches 36% (50) and acutely acquired neurological deficits lasting over 24 h 40% (56). One-seventh (20) were PWS(-). This group had: fewer lobes with angioma (p < 0.0001); and less frequent ID (p = 0.002) or language disorder (p = 0.013). Seizure frequency and status epilepticus prevalence did not differ from PWS(+). ID and language disorder were associated with: more lobes with angioma; earlier seizure onset; more frequent status epilepticus and seizure clusters. On multivariable analysis recurrent status epilepticus (p = 0.037) and multi-lobe involvement (p = 0.002) increased the risk of severe intellectual disability. Active epilepsy was associated with language disorder (p = 0.030). CONCLUSIONS: This is the largest reported series documenting detailed developmental profiles of children with SWS, including ID and ASD. PWS(+) shows high rates of ID and language disorder. PWS(-) SWS has a more favourable outcome. Cognitive outcome is contingent on number of affected lobes and bilateral involvement. Epilepsy exerts an additional deleterious effect on language and cognition. A high percentage of children have a history of status epilepticus, with evidence that this impacts language and cognitive outcomes. Acutely acquired neurological deficits did not penalise either. Regular structured clinical and developmental assessment permit greater identification of neurological and neurodevelopmental impairments in SWS, and appropriate support.

RESUMEN

OBJECTIVES: Decisions with an ethical component have been controversial during the COVID-19 pandemic, whether leaked intensive care unit (ICU)-rationing documents, transfer of people to care-homes to 'protect the National Health Service' or the duty to treat patients despite inadequate personal protective equipment. To counter criticism of ethics per se, and to help those planning ethics support we describe the practical work of a children's hospital bioethics team in supporting children, families and clinicians during this unprecedented period. DESIGN/SETTING: Three phases of activity: (i) preparation: we composed several documents to support/guide hospital teams and, together with colleagues, provided them to regional inpatient, community and hospice settings. We adapted existing mechanisms to combat workforce moral injury; (ii) activity (March-June 2020): was highest in our rapid response service where children/families consider difficult treatment decisions with medical teams. Education provided 'pandemic webcasts' on decision-making and broader child-health concerns. Staff support was essential, especially for those deployed to overwhelmed local adult ICUs. Research ascertained young people's views on the pandemic; (iii) reflection: focussed on (a) research about future re-deployment to adult services and minimisation of moral distress/injury, (b) remote video-conferencing-parents'/participants' experience/ability to consider complex ethical issues and (c) role of faith/non-faith in society's recovery and children's views. MAIN OUTCOME/CONCLUSIONS: Our bioethics team's role during the pandemic included: case reviews via video-conferencing, many involving innovative therapy for severely unwell children with COVID-19/Paediatric-Inflammatory-Multisystem Syndrome-Temporally associated with SARS-CoV-2 together with their parents; processes to protect healthcare staff from moral harm and research/educational activity focused on paediatric-specific ethical arising during the pandemic.

RESUMEN

OBJECTIVE: To characterize a cohort of children with epilepsia partialis continua (EPC) and develop a diagnostic algorithm incorporating key differential diagnoses. METHODS: Children presenting with EPC to a tertiary pediatric neurology center between 2002 and 2019 were characterized. RESULTS: Fifty-four children fulfilled EPC criteria. Median age at onset was 7 years (range 0.6-15), with median follow-up of 4.3 years (range 0.2-16). The diagnosis was Rasmussen encephalitis (RE) in 30 of 54 (56%), a mitochondrial disorder in 12 of 54 (22.2%), and magnetic resonance imaging (MRI) lesion-positive focal epilepsy in 6 of 54 (11.1%). No diagnosis was made in 5 of 54 (9%). Children with mitochondrial disorders developed EPC earlier; each additional year at presentation reduced the odds of a mitochondrial diagnosis by 26% (P = .02). Preceding developmental concerns (odds ratio [OR] 22, P < .001), no seizures prior to EPC (OR 22, P < .001), bilateral slowing on electroencephalogram (EEG) (OR 26, P < .001), and increased cerebrospinal fluid (CSF) protein level (OR 16) predicted a mitochondrial disorder. Asymmetry or hemiatrophy was evident on MRI at presentation with EPC in 18 of 30 (60%) children with RE, and in the remainder at a median of 6 months (range 3-15) after EPC onset. The first diagnostic test is brain MRI. Hemiatrophy may permit a diagnosis of RE with unilateral clinical and EEG findings. For children in whom a diagnosis of RE cannot be made on first scan but the clinical and radiological presentation resembles RE, repeat imaging every 6 months is recommended to detect progressive unicortical hemiatrophy, and brain biopsy should be considered. Evidence of intrathecal inflammation (oligoclonal bands and raised neopterin) can be supportive. In children with bihemispheric EPC, rapid polymerase gamma testing is recommended and if negative, sequencing mtDNA and whole-exome sequencing on blood-derived DNA should be performed. SIGNIFICANCE: Children presenting with EPC due to a mitochondrial disorder show clinical features distinguishing them from RE and structural epilepsies. A diagnostic algorithm for children with EPC will allow targeted investigation and timely diagnosis.

RESUMEN

INTRODUCTION: Sturge Weber Syndrome (SWS) arises from a sporadic condition secondary to a post zygotic mutation in the GNAQ gene, manifested in the majority of cases by capillary malformation of the skin. Children present with seizures, acquired hemiparesis, transient hemiparesis and intellectual disabilities. This project aimed to establish incidence of transient episodes, their recovery time if full recovery was achieved, and events associated with the transient episode. METHODS: This was a retrospective cohort study, approved for clinical audit (Institution number 2182). Children with a diagnosis of SWS seen in a tertiary multidisciplinary clinic from September 2013 to September 2016 were included in the analysis. Data was collated from clinical notes. SPSS 21 was used for analysis. RESULTS: A total of 102 patients had a diagnosed of SWS, the mean age was 10.86 years (range 2-22years). 47/102 participants with SWS had permanent hemiparesis. 32/102 presented with transient episodes. All children with transient hemiparesis had epilepsy. Median recovery time to previous function, following a transient episode was 24 h (range 1 minute-4392 h). All participants fully recovered from the transient episode within a 6 months' time frame. The factors associated with transient episodes were seizures, or a blow to the head. CONCLUSIONS: To our knowledge this is the largest cohort of children with SWS analysed to describe occurrence, association and recovery time of transient hemiparesis. The findings informed service development including change in method to record details of transient episodes. Further information provided to other health professionals will be reviewed.

RESUMEN

BACKGROUND: Children with Sturge-Weber syndrome can experience severe headache with or without transient hemiparesis. Flunarizine, a calcium antagonist, has been used for migraine. The experience with flunarizine for headache in a cohort of children at a national center for Sturge-Weber syndrome is reviewed, reporting its efficacy and adverse effect in this population. METHODS: We collected data from health care professionals' documentation on headache (severity, frequency, duration) before and on flunarizine in 20 children with Sturge-Weber syndrome. Adverse effects reported during flunarizine treatment were collated. The Wilcoxon signed rank test was used to determine the significance of pre- versus post-treatment effect. RESULTS: Flunarizine was used for headache alone (13) or mixed migrainous episodes and vascular events (7). The median duration of treatment was 145 days (range 43 to 1864 days). Flunarizine reduced headache severity (z = -3.354, P = 0.001), monthly frequency (z = -2.585, P = 0.01), and duration (z = -2.549, P = 0.01). Flunarizine was discontinued owing to intolerable adverse effects in a minority (2). Sedation and weight gain were the most common side effects. There were no reports of behavior change or extrapyramidal features. CONCLUSIONS: The most effective management for headaches in patients with Sturge-Weber syndrome has not been established. This retrospective observational study found benefit of flunarizine prophylaxis on headache severity, frequency, and duration in children with Sturge-Weber syndrome without severe side effects. Flunarizine is not licensed for use in the United Kingdom, but these data support its off-license specialist use for headache prophylaxis in Sturge-Weber syndrome.

RESUMEN

Sturge-Weber syndrome (SWS) is a neurocutaneous disorder characterized by the combination of a facial naevus flammeus and pial angioma, often associated with learning difficulties and/or epilepsy. Here, we report on the neuropsychological characteristics of a cohort of 92 children with SWS seen at a national referral center between 2002 and 2015. Almost a quarter (24%) had a diagnosis of autism spectrum disorder (ASD), with 45% overall having evidence of social communication difficulties (SCD). Autism spectrum disorder was more commonly seen in those individuals with bilateral angioma (p = 0.021). Significant behavioral difficulties were reported in 50% while 26% had difficulties with sleep. Difficulties with social communication, behavior, and sleep were closely associated with one another. They were not, however, significantly associated with markers of epilepsy severity and were noted to occur even in children without epilepsy. The prevalence of ASD/SCD, sleep difficulties, and behavioral disorders seen in SWS is high and reflects the complex needs of this group.

RESUMEN

OBJECTIVE: Provide data on the distribution of parent- and teacher-reported symptoms of ADHD in childhood epilepsy and describe coexisting cognitive and behavioral disorders in children with both epilepsy and ADHD. METHOD: Eighty-five (74% of those eligible) children (5-15 years) in a population-based sample with active epilepsy underwent psychological assessment. The ADHD Rating Scale-IV (ADHD-RS-IV) scale was completed by parents ( n = 69) and teachers ( n = 67) of participating children with an IQ > 34. ADHD was diagnosed with respect to Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.). RESULTS: Parents reported significantly more symptoms of ADHD than teachers ( p < .001). Symptoms of inattention were more commonly reported than symptoms of hyperactivity-impulsivity ( p < .001). Neurobehavioral comorbidity was similar in those with ADHD and non-ADHD with the exception of oppositional defiant disorder (ODD) and developmental coordination disorder (DCD), which were more common in those with both epilepsy and ADHD. CONCLUSION: Symptoms of ADHD are very common in childhood epilepsy but prevalence is influenced by informant.

RESUMEN

METHODS: Children (5-15 years) with active epilepsy were screened using the parent-report (n=69) and self-report (n=48) versions of the Spence Children's Anxiety Scale (SCAS) and the self-report version of the Children's Depression Inventory (CDI) (n=48) in a population-based sample. RESULTS: A total of 32.2% of children (self-report) and 15.2% of children (parent-report) scored ≥1 SD above the mean on the SCAS total score. The subscales where most difficulty were reported on parent-report were Physical Injury and Separation Anxiety. There was less variation on self-report. On the CDI, 20.9% of young people scored ≥1 SD above the mean. Children reported significantly more symptoms of anxiety on the SCAS total score and three of the subscales (p<.05). There was a significant effect on the SCAS total score of respondents by seizure type interaction, suggesting higher scores on SCAS for children with generalized seizures on self- but not parent-report. Higher CDI scores were significantly associated with generalized seizures (p>.05). SUMMARY: Symptoms of anxiety were more common based on self-report compared with parent-report. Children with generalized seizures reported more symptoms of depression and anxiety.

RESUMEN

Alternating hemiplegia of childhood is a rare disorder caused by de novo mutations in the ATP1A3 gene, expressed in neurons and cardiomyocytes. As affected individuals may survive into adulthood, we use the term 'alternating hemiplegia'. The disorder is characterized by early-onset, recurrent, often alternating, hemiplegic episodes; seizures and non-paroxysmal neurological features also occur. Dysautonomia may occur during hemiplegia or in isolation. Premature mortality can occur in this patient group and is not fully explained. Preventable cardiorespiratory arrest from underlying cardiac dysrhythmia may be a cause. We analysed ECG recordings of 52 patients with alternating hemiplegia from nine countries: all had whole-exome, whole-genome, or direct Sanger sequencing of ATP1A3. Data on autonomic dysfunction, cardiac symptoms, medication, and family history of cardiac disease or sudden death were collected. All had 12-lead electrocardiogram recordings available for cardiac axis, cardiac interval, repolarization pattern, and J-point analysis. Where available, historical and prolonged single-lead electrocardiogram recordings during electrocardiogram-videotelemetry were analysed. Half the cohort (26/52) had resting 12-lead electrocardiogram abnormalities: 25/26 had repolarization (T wave) abnormalities. These abnormalities were significantly more common in people with alternating hemiplegia than in an age-matched disease control group of 52 people with epilepsy. The average corrected QT interval was significantly shorter in people with alternating hemiplegia than in the disease control group. J wave or J-point changes were seen in six people with alternating hemiplegia. Over half the affected cohort (28/52) had intraventricular conduction delay, or incomplete right bundle branch block, a much higher proportion than in the normal population or disease control cohort (P = 0.0164). Abnormalities in alternating hemiplegia were more common in those ≥16 years old, compared with those <16 (P = 0.0095), even with a specific mutation (p.D801N; P = 0.045). Dynamic, beat-to-beat or electrocardiogram-to-electrocardiogram, changes were noted, suggesting the prevalence of abnormalities was underestimated. Electrocardiogram changes occurred independently of seizures or plegic episodes. Electrocardiogram abnormalities are common in alternating hemiplegia, have characteristics reflecting those of inherited cardiac channelopathies and most likely amount to impaired repolarization reserve. The dynamic electrocardiogram and neurological features point to periodic systemic decompensation in ATP1A3-expressing organs. Cardiac dysfunction may account for some of the unexplained premature mortality of alternating hemiplegia. Systematic cardiac investigation is warranted in alternating hemiplegia of childhood, as cardiac arrhythmic morbidity and mortality are potentially preventable.

RESUMEN

INTRODUCTION: There is a lack of population-based data on specific cognitive profiles in childhood epilepsy. This study sought to determine the frequency of impairments in global cognition and aspects of working memory and processing speed in a population-based sample of children with "active" epilepsy (on antiepileptic Drugs (AEDs), and/or had a seizure in the last year). Factors significantly associated with global and specific difficulties in cognition were also identified. METHOD: A total of 85 (74% of eligible population) school-aged children (5-15 years) with "active" epilepsy underwent comprehensive psychological assessment including assessment of global cognition, working memory, and processing speed. Scores on cognitive subtests were compared via paired-samples t tests. The factors associated with cognitive difficulties were analyzed via linear regression. RESULTS: A total of 24% of children were functioning below IQ 50, and 40% had IQ scores below 70. Scores on the Processing Speed Index were significantly lower than scores on the Verbal or Performance indexes on Wechsler instruments. The Coding subtest was a significant weakness compared with the other Wechsler subtests. A total of 58% of children displayed "memory underachievement" (memory score 1 SD below assessed IQ) on at least one of the four administered working memory subtests. Factors significantly associated with globally impaired cognition included being on polytherapy (ß = -13.0; 95% CI [-19.3, -6.6], p = .000) and having attention-deficit/hyperactivity disorder (ADHD; ß = -11.1, 95% CI [-3.0, -19.3], p = .008). Being on polytherapy was also associated with lower scores on the working memory and processing speed composite scores. Having developmental coordination disorder (DCD) was associated with a lower score on the processing speed composite. CONCLUSIONS: There is a high rate of global and specific cognitive difficulties in childhood epilepsy. Difficulties are most pronounced in aspects of working memory and processing speed. Predictors of cognitive impairment in childhood epilepsy include epilepsy-related and behavioral factors, which may differ depending on the domain of cognition assessed.

RESUMEN

AIMS: To provide data on parent-reported features of developmental coordination disorder (DCD) and describe neurobehavioural comorbidity in children with epilepsy and DCD. METHOD: Eighty-five (74% of those eligible) children (44 males, 41 females; age range 5-15y) with active childhood epilepsy (an epileptic seizure in the last year and/or currently taking antiepileptic drugs) in a population-based cohort underwent comprehensive multidisciplinary assessment. The DCD Questionnaire (DCD-Q) was completed by parents (n=69) of children with an IQ>34, of whom 56 did not have cerebral palsy (CP), and were considered for a diagnosis of DCD. RESULTS: Of those considered for a DCD diagnosis, 16 (29%) met DSM-IV-TR criteria whereas 34 (61%) scored in the at-risk range on the DCD-Q. The sensitivity of the DCD-Q was 100% (95% CI 76-100) and specificity was 55% (95% CI 39-70). Significant predictors of higher scores on the DCD-Q included the presence of autism spectrum disorder, CP, and early seizure onset. Increasing age and IQ were independently associated with higher DCD-Q scores. Intellectual disability, attention-deficit-hyperactivity disorder, academic underachievement, and specific memory problems were the most common neurobehavioural difficulties in those with both DCD and epilepsy. INTERPRETATION: Parent-reported symptoms of DCD are very common in childhood epilepsy. The DCD-Q has good sensitivity but lower specificity in this population.

RESUMEN

BACKGROUND: Mutations in the gene encoding the alpha subunit of the voltage-gated sodium channel SCN1A are associated with several epilepsy syndromes. These range from severe phenotypes including Dravet syndrome to milder phenotypes such as genetic epilepsy with febrile seizures plus (GEFS+). To date the sequence variants identified have been heterozygous in nature as one would expect for a disorder that occurs de novo or is dominantly inherited. METHODS AND RESULTS: We report the association of two novel homozygous missense mutations of the SCN1A gene in four children with infantile epilepsies from two consanguineous pedigrees. We suggest that the nature and location of the identified amino acid changes allows heterozygous carriers to remain unaffected. However, having such changes on both alleles may have a cumulative and detrimental effect. CONCLUSION: The presented cases illustrate how better understanding of the nature and location of SCN1A missense mutations may aid the interpretation of genotype-phenotype associations. SCN1A related epilepsies should be considered in children with infantile onset epilepsies even when an autosomal recessive neurological disorder is suspected.

RESUMEN

BACKGROUND: Improving health-related quality of life (HRQOL), rather than just reducing seizures, should be the principal goal in comprehensive management of childhood epilepsy. There is a lack of population-based data on predictors of HRQOL in childhood epilepsy. METHODS: The Children with Epilepsy in Sussex Schools (CHESS) study is a prospective, population-based study involving school-aged children (5-15 years) with active epilepsy (on one or more AED and/or had a seizure in the last year) in a defined geographical area in the UK. Eighty-five of 115 (74% of eligible population) children underwent comprehensive psychological assessment including measures of cognition, behaviour, and motor functioning. Parents of the children completed the Quality of Life in Childhood Epilepsy (QOLCE).Clinical data on eligible children was extracted using a standardised pro forma. Linear regression analysis was undertaken to identify factors significantly associated with total Quality of Life in this population. RESULTS: Factors independently significantly associated (p < .05) with total QOLCE scores were seizures before 24 months, cognitive impairment (IQ < 85), anxiety, and parent reported school attendance difficulty. These factors were also significantly associated with total QOLCE when children with IQ < 50 were excluded from analysis. CONCLUSIONS: The majority of factors associated with parent reported HRQOL in active childhood epilepsy are related to neurobehavioural and/or psychosocial aspects of the condition.

RESUMEN

In a defined geographical area in the south of the UK, 115 children with active epilepsy (i.e., children who had seizures in the last year and/or children who were taking antiepileptic drugs (AEDs)) were identified via a computerized database and liaison with local pediatricians. Eighty-five (74%) of the children (5-15years of age) underwent a comprehensive psychological assessment. Twenty-one percent of the children met the DSM-IV-TR criteria for ASD, and 61% of those with ASD had another DSM-IV-TR behavioral or motor disorder. The Autism Spectrum Screening Questionnaire (ASSQ) was completed by parents (n=69) and by teachers (n=67) of children with an IQ>34. Only 9% of children on parent ratings and 15% of children on teacher ratings had no features of ASD. Parents reported significantly (p<.05) more features of ASD on the ASSQ compared with teachers. Factors significantly associated with responses on the ASSQ included respondent (parents reported more features), school placement (more features in specialized settings), and respondent by school placement interaction. Effective screening for ASD in children with epilepsy will need a consideration of the impact of informant and school placement on ratings. In conclusion, features of ASD were common in children with epilepsy regardless of cognitive ability. The ASSQ was a useful screening instrument in this population, and combining parent and teacher forms was optimal in terms of screening properties.
