Abstract
The first 6 years of life are when 90% of brain development occurs, setting the foundation for lifelong neurodevelopment. The field of infant and early childhood neurodevelopment has made marginal advancements since introduced in 1988. There remains a gap in knowledge around early neurodevelopmental domains and trajectories given that there are few established assessment procedures for infants and young children and controversies around reserving assessments until school age. Throughout this systematic review, we (1) identified neurodevelopmental assessment measures employed in the literature by domain and age of assessment, (2) compiled a repository of 608 domain-specific neurodevelopmental assessment measures, and (3) established a preliminary conceptual framework for cross-domain neurodevelopmental assessments across infancy and early childhood. This review adhered to PRISMA guidelines and spanned three databases (PsycINFO, MEDLINE, PubMed). Articles were reviewed for (1) infancy and early childhood (0-6 years), (2) neurodevelopmental measures, and (3) English language. This systematic review spanned 795 articles from 1978 to 2020 with international representation. Advancements in assessment methods (e.g. measures, domains, frameworks) are essential for the evaluation of early neurodevelopmental profiles to inform early interventions, thus harnessing the neuroplasticity and dynamic development notable during early childhood. We hope this work catalyzes future research and clinical guidelines around early assessments methods.

Predictors of neurocognitive outcome in pediatric ischemic and hemorrhagic stroke. Child Neuropsychol 2024; 30:444-461.

Abstract
This clinical study examined the impact of eight predictors (age at stroke, stroke type, lesion size, lesion location, time since stroke, neurologic severity, seizures post-stroke, and socioeconomic status) on neurocognitive functioning following pediatric stroke. Youth with a history of pediatric ischemic or hemorrhagic stroke (n = 92, ages six to 25) underwent neuropsychological testing and caregivers completed parent-report questionnaires. Hospital records were accessed for medical history. Spline regressions, likelihood ratios, one-way analysis of variance, Welch's t-tests, and simple linear regressions examined associations between predictors and neuropsychological outcome measures. Large lesions and lower socioeconomic status were associated with worse neurocognitive outcomes across most neurocognitive domains. Ischemic stroke was associated with worse outcome in attention and executive functioning compared to hemorrhagic stroke. Participants with seizures had more severe executive functioning impairments than participants without seizures. Youth with cortical-subcortical lesions scored lower on a few measures than youth with cortical or subcortical lesions. Neurologic severity predicted scores on few measures. No differences were found based on time since stroke, lesion laterality, or supra- versus infratentorial lesion. In conclusion, lesion size and socioeconomic status predict neurocognitive outcome following pediatric stroke. An improved understanding of predictors is valuable to clinicians who have responsibilities related to neuropsychological assessment and treatments for this population. Findings should inform clinical practice through enhanced appraisals of prognosis and the use of a biopsychosocial approach when conceptualizing neurocognitive outcome and setting up support services aimed at fostering optimal development for youth with stroke.

Abstract
Central nervous system involvement in HIV infection leads to neurobehavioural sequelae. Although apathy is a well-recognised symptom in adults living with HIV linked to alterations in brain structure, there is scarce research examining motivation in children living with HIV (CLWH). We used the Children's Motivation Scale (CMS; normative mean = 50, SD = 10) to assess motivation levels in 76 CLWH aged 6-16 years (63 on antiretroviral therapy [ART]; 13 ART-naïve slow progressors) in South Africa. Overall, CLWH scored low on the CMS (mean = 35.70 [SD = 5.87]). Motivation levels were significantly reduced in children taking ART compared to ART-naïve slow progressors (p = 0.02), but were not correlated with markers of HIV disease (CD4 + cell count or viral load), or neurocognitive function (p > 0.05). CMS scores were correlated with diffusion tensor imaging metrics of white matter microstructure in specific frontostriatal brain regions (p < 0.05). On multiple regression, associations with the anterior limb of the internal capsule, a subcortical white matter region, remained significant after adjusting for potential confounders. These findings suggest that reduced motivation may be an important neurobehavioural symptom in CLWH and may reflect changes in white matter microstructure of frontostriatal brain regions.

Abstract
Children who experience pediatric stroke are at higher risk for future behavioral problems in childhood. We examined the prevalence of parent reported externalizing behaviors and executive function problems in children following stroke and neurological predictors. This study included 210 children with pediatric ischemic stroke (mean age 9.18 years (SD = 3.95)). The parent form of the Behavioral Assessment System for Children-Second Edition (BASC-2) and Behavior Rating Inventory of Executive Function (BRIEF) were used to evaluate externalizing behavior and executive function. No externalizing behavior or executive function differences were found between perinatal (n = 94) or childhood (n = 116) stoke, except for the shift subscale which had higher T-scores among the perinatal group (M = 55.83) than childhood group (M = 50.40). When examined together, 10% of children had clinically elevated hyperactivity T-scores as opposed to the expected 2%. Parents endorsed higher ratings of concern on the behavior regulation and metacognition indices of the BRIEF. Externalizing behaviors were correlated moderately to strongly with executive functions (r = 0.42 to 0.74). When examining neurological and clinical predictors of externalizing behaviors, only female gender was predictive of increased hyperactivity (p = .004). However, there were no significant gender differences in diagnosis of attention deficit hyperactivity disorder (ADHD). In summary, in this cohort, children with perinatal and childhood stroke did not differ on parent reported externalizing behavior or executive function outcomes. However, compared to normative data, children with perinatal or childhood stroke are significantly more likely to experience clinically elevated levels of hyperactivity.

Abstract
Traumatic brain injury (TBI) and stroke are the most common causes of acquired brain injury (ABI), annually affecting 69 million and 15 million people, respectively. Following ABI, the relationship between brain network disruption and common cognitive issues including attention dysfunction is heterogenous. Using PRISMA guidelines, we systematically reviewed 43 studies published by February 2023 that reported correlations between attention and connectivity. Across all ages and stages of recovery, following TBI, greater attention was associated with greater structural efficiency within/between executive control network (ECN), salience network (SN), and default mode network (DMN) and greater functional connectivity (fc) within/between ECN and DMN, indicating DMN interference. Following stroke, greater attention was associated with greater structural connectivity (sc) within ECN; or greater fc within the dorsal attention network (DAN). In childhood ABI populations, decreases in structural network segregation were associated with greater attention. Longitudinal recovery from TBI was associated with normalization of DMN activity, and in stroke, normalization of DMN and DAN activity. Results improve clinical understanding of attention-related connectivity changes after ABI. Recommendations for future research include increased use of electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) to measure connectivity at the point of care, standardized attention and connectivity outcome measures and analysis pipelines, detailed reporting of patient symptomatology, and casual analysis of attention-related connectivity using brain stimulation.

Abstract
PURPOSE To provide an overview of the effects of pediatric stroke on emotional and social functioning in childhood. METHODS A literature review was completed in accordance with the Preferred Reporting Items for Systematic Reviews. A systematic search of studies on internalizing problems and social functioning after pediatric stroke in PsycInfo, PsycArticles, and PubMed databases was conducted from inception to November 2021. A total of 583 studies were identified, and 32 met the inclusion criteria. RESULTS The review suggests that children after stroke are at risk of developing internalizing problems and a wide range of social difficulties. Internalizing problems are often associated with environmental factors such as family functioning and parents' mental health. In addition, a higher risk of developing psychosocial problems is associated with lower cognitive functioning and severe neurological impairment. CONCLUSIONS The assessment of psychological well-being and social functioning after pediatric stroke is helpful to provide adequate support to children and their families. Future studies are needed to better investigate these domains and to develop adequate methodologies for specific interventions.Implication for rehabilitationThis paper reviews research concerning emotional and social functioning following pediatric stroke in order to provide helpful information to clinicians and families and to improve rehabilitation pathways.Emotional and social functioning should be addressed during post-stroke evaluation and follow-up, even when physical and cognitive recovery is progressing well.Care in pediatric stroke should include volitional treatment and address emotional and social issues.

Abstract
AIM To examine adjustment after stroke in adolescence from the perspective of affected young people. METHOD Fourteen participants (10 female) aged 13 to 25 years with a history of ischemic or hemorrhagic stroke in adolescence participated in one-on-one semi-structured interviews at the Hospital for Sick Children, Toronto, Canada. Interviews were audio-recorded and transcribed verbatim. Two independent coders conducted a reflexive thematic analysis. RESULTS Five themes were identified as representative of adjustment after stroke: (1) 'Processing the story'; (2) 'Loss and challenges'; (3) 'I've changed'; (4) 'Keys to recovery'; and (5) 'Adjustment and acceptance'. INTERPRETATION This qualitative study provides medical professionals with a personal, patient-driven lens through which to better understand the challenges of adjusting to life after pediatric stroke. Findings highlight the need to provide mental health support to patients to assist them in processing their stroke and adapting to long-lasting sequelae. WHAT THIS PAPER ADDS Processing the onset event is a key component of adjustment to stroke. Feelings of anxiety, sadness, frustration, and self-consciousness impede adjustment to stroke. Young people may feel overwhelmed academically owing to neurocognitive deficits. Sequelae may rid young people of hobbies and passions, and alter plans for the future. To adjust to stroke, survivors draw on resilience, patience, determination, and social support.

Abstract
This study examined the executive function (EF) of children with a history of arterial ischemic stroke (AIS) and preserved intellectual abilities, with reference to age at stroke onset, lesion characteristics, language, and motor functioning. In addition, the associations between EF and emotional and behavioral functioning were investigated. A battery of standardized neuropsychological tests was administered to children with previous AIS aged 7-12 in order to assess EF, including inhibition, working memory, cognitive flexibility, and attention. Parents rated questionnaires regarding real-life emotional and behavioral functioning. Finally, clinical and neuroradiological data were also gathered. Thirty patients were enrolled. Eight children fall in the lower end of the normative range or below in more than half of the EF measures, with working memory, inhibition and cognitive flexibility equally impaired, and attention relatively better preserved. Larger lesion size and language deficits were significantly associated with higher EF impairment. Emotional and behavioral functioning was lower in children with weaker EF. Children with a history of AIS, even those with preserved intellectual functioning, have a high risk of showing poor EF, mostly regardless of clinical features or functional impairment. EF difficulties are in turn associated with emotional and behavioral problems. Therefore, a standardized evaluation of EF in this population is mandatory as part of the follow-up, in order to ensure an early intervention and prevent related difficulties.

Abstract
Pediatric stroke results in life-long morbidity for many patients, but the outcomes can vary depending on factors such as age of injury, or mechanism, size, and location of stroke. In this review, we summarize the current understanding of outcomes in different neurological domains (eg, motor, cognitive, language) for children with stroke of different mechanisms (ie, arterial ischemic stroke, cerebral sinus venous thrombosis, and hemorrhagic stroke), but with a focus on World Health Organization International Classification for Functioning, Disability, and Health (ICF-CY) framework for measuring health and disability for children and youth. We describe outcomes for the population as a whole and certain factors that may further refine prognostication.

Abstract
Pediatric stroke is associated with a range of maladaptive cognitive and behavioral outcomes that often require targeted intervention. Despite increasing research on neuropsychological outcomes over the past decade, evidence for effective therapies and interventions for the most commonly reported cognitive and behavioral challenges is still limited. The most widely prescribed interventions address more overt deficits in sensorimotor and speech/language functions, yet interventions for higher-order cognitive, linguistic and behavioral deficits are notably less defined. Moreover, concepts of rehabilitation in adult stroke cannot be easily translated directly to pediatric populations because the effect of stroke and recovery in the developing brain takes a very different course than in the mature brain. In pediatric stroke, neuropsychological deficits often emerge gradually over time necessitating a long-term approach to intervention. Furthermore, family and school context often play a much larger role. The goal of this review is to describe cognitive and behavioral interventions for perinatal and childhood stroke, as motor rehabilitation is covered elsewhere in this issue. We also discuss cognitive aspects of current rehabilitative therapies and technology. Acknowledging the current limited state of stroke-specific rehabilitation research in children, findings from pediatric acquired brain injury intervention and use of transdiagnostic approaches lend important insights. Because there is limited support for single domain (cognitive) trainings and translation of research rehabilitation programs to clinical practice can be challenging, the value of holistic multidisciplinary approaches to improve everyday function in children and adolescents following stroke is emphasized.

Abstract
IMPORTANCE Early detection of attention-deficit/hyperactivity disorder (ADHD) plays a crucial role in reducing negative effects on everyday life, including academic failure and poor social functioning. Children who survive ischemic strokes risk major disabilities, but their risk of ADHD has not been studied in nationwide cohorts. OBJECTIVE To assess the risk of ADHD in children after pediatric ischemic stroke. DESIGN, SETTING, AND PARTICIPANTS Participants in this Swedish nationwide cohort study included 1320 children diagnosed with ischemic stroke recorded in linked Swedish national registers from January 1, 1969, to December 31, 2016, without prior ADHD diagnosis. Ten matched controls were identified for each index case, and first-degree relatives were identified for index individuals and controls. Analyses were stratified by perinatal and childhood strokes and presence of comorbid adverse motor outcomes and/or epilepsy. End of follow-up was the date of ADHD diagnosis, death, or December 31, 2016, whichever occurred first. Data analyses were performed August 1 to 28, 2021. EXPOSURES Pediatric ischemic stroke. MAIN OUTCOMES AND MEASURES Attention-deficit/hyperactivity disorder identified using codes from the International Classification of Diseases, Ninth Revision, and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, and/or prescribed ADHD medication recorded in the Medical Birth Register, National Patient Register, or Prescribed Drug Register after stroke. Cox proportional hazards regression was used to assess adjusted hazard ratios (aHRs) for ADHD after pediatric stroke, adjusting for parental age and ADHD in first-degree relatives. RESULTS Of 1320 children with stroke included in the analysis (701 boys [53.1%]), 75 (45 boys [60.0%]) were diagnosed with ADHD after stroke compared with 376 (252 boys [67.0%]) among the controls (aHR, 2.00 [95% CI, 1.54-2.60]). The risk was increased after both perinatal (aHR, 2.75 [95% CI ,1.65-4.60]) and childhood (aHR, 1.82 [95% CI, 1.34-2.48]) strokes and were similar if children born preterm or small for gestational age were excluded. Compared with controls, risks of ADHD were higher among children with perinatal stroke and adverse motor outcomes and/or epilepsy (aHR, 6.17 [95% CI, 2.80-13.62]) than among those without these comorbidities (aHR, 1.65 [95% CI, 0.80-3.42]). However, findings were similar in childhood stroke for children with adverse motor outcomes and/or epilepsy (aHR, 1.80 [95% CI, 1.12-2.89]) and among those without these comorbidities (aHR, 1.92 [95% CI, 1.28-2.90]). CONCLUSIONS AND RELEVANCE This cohort study of 1320 children with pediatric ischemic stroke suggests that there is an increased risk of ADHD, particularly in children with adverse motor outcomes and/or epilepsy, compared with controls. The risk increases after childhood strokes regardless of comorbidities.

Abstract
Paediatric arterial ischaemic stroke is an important cause of neurological morbidity in children, with consequences including motor disorders, intellectual impairment, and epilepsy. The causes of paediatric arterial ischaemic stroke are unique compared with those associated with stroke in adulthood. The past decade has seen substantial advances in paediatric stroke research and clinical care, but many unanswered questions and controversies remain. Shortage of prospective evidence for the use of recanalisation therapies in patients with paediatric stroke has resulted in little standardisation of disease management. Substantial time delays in diagnosis and treatment continue to challenge best possible care. In this Review, we highlight on some of the most pressing and productive aspects of research in the treatment of arterial ischaemic stroke in children, including epidemiology and cause, rehabilitation, secondary stroke prevention, and treatment updates focusing on advances in hyperacute therapies such as intravenous thrombolysis, mechanical thrombectomy, and critical care. Finally, we provide a future perspective for improving outcomes and quality of life for affected children and their families.

Abstract
OBJECTIVE To evaluate concordance between prenatal and postnatal diagnosis of congenital talipes equinovarus (cTEV), rates of surgery and postnatal outcomes in relation to the prenatal classification of severity. STUDY DESIGN This is a retrospective observational cohort study on fetuses with a prenatal diagnosis of cTEV between 2004 and 2018. All cases of isolated cTEV in singleton pregnancies were included. Postnatally, the Ponseti method was applied. Children were followed-up postnatally for at least two years, with a specific focus on neurodevelopmental outcome. RESULTS The cohort included 81 fetuses with a prenatal diagnosis of cTEV confirmed postnatally in 86.4% of cases. Concordance between prenatal and postnatal assessment was good for both laterality and degree of severity (k = 0.61 and 0.66, respectively). The average Pirani score, number of casts and rates of Achilles tendon tenotomy were higher for III degree cTEV (p < 0.001). Within this group only, the rate of relapse was 11% and the rates of major surgery was 6%. The postnatal outcome was normal in 68.6% newborns, while 14% of cases had a diagnosis of minor additional findings and 17% had an impairment of neurological development. None of the outcome was statistically correlated to the prenatal assessment of laterality or degree. CONCLUSIONS The accuracy of prenatal ultrasound for isolated cTEV is 86% with a false positive diagnosis of 14%. The grade of cTEV assigned prenatally correlates to postnatal severity and longer orthopedic rehabilitation in terms of number of casts and need of surgery. The assessment of the correlation between cTEV and neurological impairment requires further prospective studies on larger cohorts.

Abstract
OBJECTIVE Pediatric strokes are rare events that can lead to neuropsychological impairment or disability. While motor deficits are relatively easy to identify and investigate, cognitive outcomes after stroke are more complex to define. Many studies have focused on global cognitive outcomes, while only a few recent studies have focused on specific cognitive processes. The aims of the present review were to provide an overview of the effects of pediatric strokes on executive function and to investigate the relations between executive functioning and clinical factors. METHOD Studies concerning executive functioning after pediatric stroke were identified using PsycInfo, PsycArticles and PubMed. A total of 142 studies were identified, and 22 met the inclusion criteria. RESULTS The review of the 22 studies included clearly indicates that childhood and perinatal strokes can affect executive function, and in particular inhibition. In contrast, the results concerning clinical factors related to EF outcomes are inconsistent. DISCUSSION Our results highlight the importance to assess EF following pediatric stroke. Early identification of difficulties in EF is crucial to provide adequate training to the children and to prevent the development of other correlated difficulties, such as behavioral problems or learning difficulties. Methodological issues regarding the heterogeneity of samples and measurement difficulties limit the conclusions that can be made about the clinical predictors of the outcomes. Studies are needed to better understand this aspect and to develop adequate EF interventions for children following stroke.

Abstract
Although pediatric stroke is associated with higher survival rates compared with adult stroke, a substantial body of evidence indicates significant neuropsychologic morbidity in pediatric stroke survivors. Neuroplasticity does not guarantee good outcome in children. The general trends observed in the literature are reviewed as is the profile observed in common causes of pediatric stroke: congenital heart disease, moyamoya disease, and sickle cell disease. The neuropsychologic profile of pediatric stroke patients is heterogeneous due to the multiplicity of associated causes. Stroke in early infancy and large strokes are associated with cognitive impairment while more limited disorders, such as phasic deficit, are observed in childhood stroke. Executive dysfunction is common in pediatric stroke, but social interaction skills are usually preserved. Congenital heart disease and sickle cell disease are associated with global neuropsychologic dysfunction while cognition is usually preserved in moyamoya. Executive dysregulation is instead more frequently reported in this population. Further study of maladaptive processes after pediatric stroke will allow identification of predictors of functional and neuropsychologic outcomes and permit personalization of care.

Abstract
The majority of pediatric neuropsychological stroke research has focused on perinatal stroke outcomes given its relative frequency. Meanwhile, childhood-onset stroke is under-represented in the literature, resulting in limited knowledge about its neurocognitive sequelae. This retrospective study examined cognitive outcomes in children and youth (n = 27) with childhood arterial ischemic stroke (stroke occurring between 29 days and 18 years of life) isolated to the cortical region. Intellectual, academic, language, visual-perception, visual-motor integration, fine motor coordination, and executive function scores were examined relative to normative means. Results indicate that although these children are doing well in terms of general intellectual ability, they demonstrate lower scores on tasks of processing speed and fine motor coordination. Exploratory analysis also revealed that of the personal and neurologic factors examined, age at stroke was positively correlated with perceptual reasoning and fine motor control, age at assessment was negatively correlated with math calculation abilities, and maternal education was positively correlated with working memory and parent-reported behavioral regulation and impulse inhibition abilities. While neurologic variables were not predictive of cognitive neuropsychological outcomes, those with significant poorer performance had higher rates of medium/large, right-sided lesions with frontal lobe involvement. Our results highlight the overall resilience of the injured developing brain but also the vulnerability of specific cognitive skills within this unique population.

Abstract
The aim of this study was to evaluate the clinical characteristics, risk factors, treatment, and outcomes of pediatric stroke cases. A total of 118 patients diagnosed with arterial ischemic stroke (AIS), hemorrhagic stroke, and sinovenous thrombosis (SVT) between January 2000 and December 2011 were included. Neonatal cases were excluded. Demographic and clinical findings were retrospectively examined from medical records. We identified 118 patients with stroke. The age of the patients ranged from 1 to 215 months (17.92 y), with a mean age of 5.19±5.25 years. AIS accounted for the majority of cases (n=69, 58.5%), and the major etiology was cardiac disease (17%). Hemorrhagic stroke accounted for 19.5% (n=23) of the cases, and late hemorrhagic disease of the newborn was the major etiology (43%, n=10). SVT accounted for 22% (n=26) of the cases, and the major etiology was otitis media-mastoiditis (27%, n=7). Hemiplegia and headache were the most frequent symptoms for AIS and SVT, respectively. Stroke is rare in children compared with adults; however, it is detected more frequently with better imaging techniques and increased awareness. We found that children with AIS presented more commonly with hemiplegia and children with SVT with headache and strabismus. We did not find an association between thrombophilia and stroke.

Abstract
The purpose of this study was to investigate language and cognitive outcomes following severe childhood stroke, and the role of age at stroke according to lesion lateralization. We retrospectively included children consecutively admitted to a physical medicine and rehabilitation department between 1992 and 2015 following childhood stroke (age at stroke 1 month to15 years). Data collection included demographic and clinical information, results of cognitive assessments on the Wechsler Intelligence scales, detailed language assessments by speech and language therapists, and long-term academic outcome. Overall, 184 children (52% boys; mean age at assessment = 8.5 years, range .7-15.4 years) were hospitalized following ischemic (n = 79) or hemorrhagic (n = 105) stroke. After a median time since stroke of 4 months (n = 135), mean Full-Scale, Verbal, and Performance Intellectual Quotient (FSIQ, VIQ and PIQ) were 85 (SD = 19), 93 (SD = 22), and 85 (SD = 20), respectively. In language tests (n = 130) assessing lexical and syntactic expression and comprehension, 26%-53% of the children exhibited impairments (scores <2SD). After a median follow-up of 40 months, only 27% of the children were following a normal curriculum without adaptations or delay, and 27% were attending special education programs. School situation was strongly associated with language and FSIQ scores. Language and verbal IQ scores were significantly lower (p < .01) among patients with lesions in the left hemisphere as opposed to the right. After a left hemisphere lesion, language skills were not associated with age at stroke, but for right hemisphere lesions, language was more impaired among children who were younger at stroke onset. PIQ tended to correlate positively with age at stroke in left hemisphere lesions (poorer PIQ in early lesions) and negatively for right hemisphere lesions (poorer PIQ in late lesions). These findings, discussed in the light of the brain vulnerability and plasticity hypotheses, are in favor of a developmental view of hemispheric specialization.

Abstract
PURPOSE Treatment of idiopathic clubfoot (IC) has improved since the introduction of the Ponseti method. However, relapses are still common and primarily related to non-adherence to the brace regime. Our hypothesis was that IC might be more than just a structural deformity. Based on three studies, the aim of this paper was to provide an overview of findings regarding additional challenges within IC. METHODS In total, 153 children with IC and 137 control children participated in the studies. The first study assessed gross motor skills in six motor tasks using the Clubfoot Assessment Protocol. The second and third studies surveyed neurodevelopmental difficulties (NDDs) using the Five to Fifteen (FTF) questionnaire and health-related quality of life (HRQoL) using the EuroQol-5D youth. RESULTS A high percentage of gross motor deviations were found in children with IC compared with controls, and those correlated poorly with clubfoot severity and foot movement. Children with IC had a higher prevalence of NDDs on the FTF compared with the control group, including the domains: motor skills, perception and language. One-third of children with IC were defined as at risk of developmental disorders. In this subgroup, parents were less satisfied with the outcome of clubfoot treatment and the children reported worse HRQoL than those without NDDs. CONCLUSION The findings suggest additional challenges in children with IC, such as NDDs, apparently affecting both clubfoot treatment outcome and HRQoL. Thus, awareness of these challenges could be vital to further optimize treatment and support, for example, with regards to brace adherence. LEVEL OF EVIDENCE II - Prognostic study.

Abstract
AIM To evaluate neurodevelopmental difficulties in children with idiopathic clubfoot. METHOD A cross-sectional study of 106 children (29 females, 77 males; aged 8-10y) with idiopathic clubfoot and 109 age-, sex-, and residential area-parallelized children from the general population. Neurodevelopmental difficulties were assessed using the parent-report Five to Fifteen (FTF) questionnaire. Group differences were analysed for FTF domains, subdomains, and items. The 90th centile cut-off of the general population on FTF and the parent-based disease-specific instrument (DSI) were used to evaluate clinical relevance of neurodevelopmental symptoms in idiopathic clubfoot. RESULTS Modest group differences were found for several FTF domains (motor skills, perception, and language) and subdomains (gross and fine motor skills, relation in space, comprehensive and expressive language skills). Thirty-one per cent of the children with idiopathic clubfoot scored in the clinically significant range on 2 or more FTF domains. DSI scores were lower in this subgroup. INTERPRETATION Findings indicate a moderate and selective increase of neurodevelopmental difficulties in children with idiopathic clubfoot as a whole, especially in the areas of motor skills, perception, and language. Idiopathic clubfoot with marked neurodevelopmental symptoms are associated with less satisfaction of the clubfoot treatment. Our results recommend awareness of neurodevelopmental difficulties in the assessment and treatment of idiopathic clubfoot. WHAT THIS PAPER ADDS A substantial minority of children with idiopathic clubfoot show neurodevelopmental difficulties. Children with idiopathic clubfoot might present additional difficulties in motor skills, perception, and language. Children with idiopathic clubfoot and marked neurodevelopmental symptoms show poorer parent-reported clubfoot treatment satisfaction. Neurodevelopmental difficulties should be considered in clinical practice of idiopathic clubfoot.

Abstract
PURPOSE OF REVIEW The past 20 years have seen a 35% increase in prevalence of pediatric stroke. Contrary to widely held views, children do not recover better than adults. This review explores the impact of pediatric stroke on cognitive domains, including intellectual and executive functions, memory and behavior, and the influence of age, lesion characteristics, and comorbidities on outcome. RECENT FINDINGS Cognitive problems occur in up to half of ischemic and hemorrhagic stroke survivors. Single-center studies have shown intelligence quotient scores skewed to the lower end of the average range, with greater impairment in performance than verbal domains. Executive function, such as attention and processing speed are particularly vulnerable to the effects of pediatric stroke. Age at stroke, larger infarct size, cortical/subcortical lesion location, epilepsy, and comorbid physical deficits are associated with poorer cognitive outcomes. SUMMARY Cognitive impairment occurs relatively frequently following pediatric stroke but the nature, severity, and predictors of specific deficits are not well defined. Improving understanding of outcomes following pediatric stroke is a key priority for families but a paucity of data limits the ability to develop targeted disease, and age-specific pediatric rehabilitation strategies to optimize cognitive outcomes following pediatric stroke.

Abstract
OBJECTIVES The aim of this paper was to critically review the recent literature on psychosocial and behavioral outcome following childhood stroke, to assess whether quality of life is affected and to investigate the factors related to psychosocial outcome. METHODS Literature searches were conducted and identified 36 relevant papers from the period 1908-2016. RESULTS The systematic review found that many children experience difficulties in a wide range of psychosocial domains. Quality of life can also be significantly reduced. Inconsistent findings regarding the correlates of outcome are likely due to methodological limitations. These issues include small and heterogeneous samples, lack of control groups, and measurement difficulties. CONCLUSIONS This systematic review strongly indicates that childhood stroke can affect a myriad of psychosocial domains and a child's quality of life. Methodological issues, particularly around heterogeneous samples and measures, limit the conclusions that can be drawn regarding the predictors of outcome.

Abstract
AIM Childhood stroke disrupts brain development and emerging neural networks. Motor, cognitive, and language deficits are well recognized, yet little is known about psychosocial function after childhood stroke. This study aims to describe psychosocial function within the first year after childhood stroke, and to identify factors associated with outcome. METHOD Thirty-seven children were involved in a prospective, longitudinal study investigating recovery over the first year after childhood stroke. Children's social functioning was assessed at 6-months and 12-months poststroke and psychological function at 12-months poststroke, using standardized measures. RESULTS Mean social function was poorer at both 6-months and 12-months poststroke, compared to prestroke. Psychological problems were more common than expected, with emotional difficulties and hyperactivity-inattention most significantly affected. Poorer social function was associated with older age at onset, acute neurological impairment, and prestroke social impairment. Social and psychological problems were associated with parent mental health. INTERPRETATION While not all children are affected, psychosocial impairment affects a significant minority after childhood stroke. Older age at onset, acute neurological impairment, prestroke social problems, and poorer parent mental health were associated with deficits. Identifying early predictors of poorer outcome will facilitate early intervention. Of particular importance is parent mental health, suggesting support for families may improve child outcome.

Abstract
AIM Little is known about psychological and social outcomes after paediatric stroke. This study aimed to evaluate psychosocial outcomes in children 5 years after paediatric stroke and explore the contribution of early presenting factors. METHOD Thirty-one children (19 males, 12 females) with arterial ischemic stroke were involved in this prospective, longitudinal study. Children underwent intellectual assessment at 12 months poststroke and parents completed questionnaires rating their own mental health and their child's functioning at 12 months and 5 years poststroke. RESULTS At 5-year follow-up, psychological and social function were significantly poorer than normative expectations. Exploration of early predictive factors showed poorer cognitive and psychological function at 12 months poststroke and older age at stroke onset was associated with poorer psychosocial function at 5 years. Larger lesion size was also associated with poorer psychological function at 5 years poststroke. INTERPRETATION These early predictors of poorer psychosocial outcome suggest that screening children within the first year after stroke may identify children most at risk of later problems and facilitate early intervention.

Abstract
Environmental factors play a key role in the development of Attention-Deficit/Hyperactivity Disorder (ADHD), but the long-term effects of these factors are still unclear. This study analyses data from 1024 monozygotic (identical) twins in Australia, the United States, and Scandinavia who were assessed for ADHD in Preschool, Kindergarten, Grade 1, and Grade 2. Differences within each twin pair were used as a direct measure of non-shared environmental effects. The Trait-State-Occasion (TSO) model developed by Cole et al. (Psychological Methods, 10, 3-20, 2005) was used to separate the non-shared environmental effects into stable factors, and transient factors that excluded measurement error. Stable factors explained, on average, 44 % and 39 % of the environmental variance in hyperactive-impulsive and inattentive symptoms, respectively. Transient effects explained the remaining 56 % and 60 % of variance. The proportion of stable variance was higher than expected based on previous research, suggesting promise for targeted interventions if future research identifies these stable risk factors.

Abstract
There is a dearth of research examining working memory (WM) following pediatric arterial ischemic stroke (AIS). This study assesses the WM patterns of 32 children, aged 6 to 14 years, with a history of unilateral AIS and 32 controls using a paradigm based on Baddeley and Hitch's multi-component WM model. The results indicate compromised WM in children with AIS relative to controls and parent reports confirm higher rates of dysfunction. Supplementary analyses of impairment confirm higher rates in children with AIS, ranging from 31.25% to 38.70% on performance-based measures and 50.00% on parent reports, compared to 0.00% to 21.88% on performance-based measures in controls and 15.63% on parent reports. Continual follow-up is recommended given that a subset of children with stroke appear to be at risk for WM impairment. Moreover, the subtle nature of WM challenges experienced by many children who have experienced a stroke increases the likelihood that WM impairment could go undetected. The long-term trajectories of WM in the pediatric stroke population remains unknown and future studies are needed to track changes in WM functioning over time.

Abstract
OBJECTIVES To investigate neuropsychological and neurobehavioral outcome in children with arterial ischemic stroke (AIS). BACKGROUND Childhood stroke can have consequences on motor, cognitive, and behavioral development. We present a cross-sectional study of neuropsychological and neurobehavioral outcome at least one year poststroke in a uniquely homogeneous sample of children who had experienced AIS. METHOD Forty-nine children with AIS aged 6 to 18 years were recruited from a specialist clinic. Neuropsychological measures of intelligence, reading comprehension, attention, and executive function were administered. A triangulation of data collection included questionnaires completed by the children, their parents, and teachers, rating behavior, executive functions, and emotions. KEY FINDINGS Focal neuropsychological vulnerabilities in attention (response inhibition and dual attention) and executive function were found, beyond general intellectual functioning, irrespective of hemispheric side of stroke. Difficulties with emotional and behavioral regulation were also found. Consistent with an "early plasticity" hypothesis, earlier age of stroke was associated with better performance on measures of executive function. CONCLUSIONS A significant proportion of children poststroke are at long-term risk of difficulties with emotional regulation, executive function, and attention. Data also suggest that executive functions are represented in widespread networks in the developing brain and are vulnerable to unilateral injury.

Abstract
OBJECTIVES To investigate the presence of apathy symptoms in adolescents and adults with ADHD as a behavioral manifestation of underlying motivational deficits and to determine whether apathy symptoms were associated with a specific neuropsychological profile. METHOD A total of 38 ADHD participants (28 of the combined subtype [ADHD/C] and 10 of the inattentive subtype [ADHD/I]) and 30 healthy controls (Ctrl) were assessed on two measures of apathy administered to subjects and informants. As well, ADHD participants completed a comprehensive neuropsychological battery. RESULTS ADHD participants presented elevated scores on measures of apathy relative to controls (ADHD/I > ADHD/C > Ctrl). Informant-based ratings of apathy correlated significantly with behavioral measures of inattention. Apathy measures correlated significantly with executive tests, working memory, verbal fluency, and general intellectual abilities, only in the inattentive sample. CONCLUSIONS This study stresses the relevance of motivational deficits in adult ADHD as a significant clinical dimension closely linked to inattention and executive difficulties.

Abstract
Stroke in the developing brain is an important cause of chronic neurological morbidities including neurobehavioral dysfunction and epilepsy. Here, we describe a mouse model of neonatal stroke resulting from unilateral carotid ligation that results in acute seizures, long-term hyperactivity, spontaneous lateralized circling behavior, impaired cognitive function, and epilepsy. Exploration-dependent induction of the immediate early gene Arc (activity-regulated cytoskeleton associated protein) in hippocampal neurons was examined in the general population of neurons versus neurons that were generated approximately 1 week after the ischemic insult and labeled with bromodeoxyuridine. Although Arc was inducible in a network-specific manner after severe neonatal stroke, it was impaired, not only in the ipsilateral injured but also in the contralateral uninjured hippocampi when examined 6 months after the neonatal stroke. Severity of both the stroke injury and the acquired poststroke epilepsy negatively correlated with Arc induction and new neuron integration into functional circuits in the injured hippocampi.

Abstract
Cerebrovascular complications are being frequently recognized in the pediatric intensive care unit in the recent few years. The epidemiology and risk factors for pediatric stroke are different from that of the adults. The incidence of ischemic stroke is almost slightly more than that of hemorrhagic stroke. The list of diagnostic causes is increasing with the availability of newer imaging modalities and laboratory tests. The diagnostic work up depends on the age of the child and the rapidity of presentation. Magnetic resonance imaging, computerized tomography and arteriography and venography are the mainstay of diagnosis and to differentiate between ischemic and hemorrhagic events. Very sophisticated molecular diagnostic tests are required in a very few patients. There are very few pediatric studies on the management of stroke. General supportive management is as important as the specific treatment. Most of the treatment guidelines and suggestions are extrapolated from the adult studies. Few guidelines are available for the use of anticoagulants and thrombolytic agents in pediatric patients. So, our objective was to review the available literature on the childhood stroke and to provide an insight into the subject for the pediatricians and critical care providers.

Abstract
Background To study motor ability at seven years of age in children treated for idiopathic clubfoot and its relation to clubfoot laterality, foot status and the amount of surgery performed. Methods Twenty children (mean age 7.5 years, SD 3.2 months) from a consecutive birth cohort from our hospital catchments area (300.000 inhabitants from southern Sweden) were assessed with the Movement Assessment Battery for Children (MABC) and the Clubfoot Assessment Protocol (CAP). Results Compared to typically developing children an increased prevalence of motor impairment was found regarding both the total score for MABC (p < 0.05) and the subtest ABC-Ball skills (p < 0.05). No relationship was found between the child's actual foot status, laterality or the extent of foot surgery with the motor ability as measured with MABC. Only the CAP item "one-leg stand" correlated significantly with the MABC (rs = -0.53, p = 0.02). Conclusions Children with idiopathic clubfoot appear to have an increased risk of motor activity limitations and it is possible that other factors, independent of the clinical status, might be involved. The ability to keep balance on one leg may be a sufficient tool for determining which children in the orthopedic setting should be more thoroughly evaluated regarding their neuromotor functioning.

Abstract
Zusammenfassung: Fragestellung: Es wird geklärt, ob es nach Schlaganfällen im Kindes- und Jugendalter zu Aufmerksamkeitsstörungen kommt und welche Einflussfaktoren vorliegen. Methodik: Es wurden die Aufmerksamkeitsleistungen von 78 schlaganfallerkrankten Kindern in Untertests der Testbatterie zur Aufmerksamkeitsprüfung (TAP) sowie der Testbatterie zur Aufmerksamkeitsprüfung für Kinder (KITAP) ausgewertet. Darüber hinaus wurden der Elternfragebogen der CBCL/4-18 sowie eine während der Untersuchung dokumentierte und standardisierte Verhaltensbeobachtung eingesetzt. Die Ergebnisse werden u.a. nach Alter zum Zeitpunkt des Schlaganfalls, betroffener Hemisphäre und Lokalisation des Schlaganfalls miteinander verglichen. Ergebnisse: Nach Schlaganfällen im Kindes- und Jugendalter kommt es vermehrt zu Störungen der Aufmerksamkeitsleistungen. Das Geschlecht, das Alter zum Zeitpunkt des Schlaganfalls und die Lokalisation der Hirnschädigung (kortikal vs. subkortikal) zeigen keinen signifikanten Einfluss. Tendenziell treten Aufmerksamkeitsstörungen häufiger nach rechtshemisphärischen Schlaganfällen auf. Schlussfolgerungen: Es besteht die Notwendigkeit einer frühen Diagnosestellung und wirksamen Behandlung, um der Entstehung komorbider Störungen und Schulschwierigkeiten vorzubeugen.

Abstract
Childhood stroke syndromes are an important cause of mortality and morbidity. This paper focuses on the recent advances in arterial ischaemic stroke beyond the neonatal period. Vascular risk factors are identified in the majority of children and guide both acute and longer term treatments, as well as determining prognosis. Contrary to popular belief many children have residual impairments encompassing a wide range of domains. National and international collaborations are facilitating an increase in the understanding of childhood stroke and have the eventual aim of conducting trials of potential therapeutic interventions.

Abstract
PURPOSE Conflicting evidence about impairment of attention systems and the absence of a working model of attention has contributed to lack of clarity about comorbidity of attention problems in rolandic epilepsy (RE). Impairments in distributed attention systems may inform a disease model for RE, as well as direct interventions. METHODS We used a systematic review of the relevant literature published in English from 1990 to 2006 to evaluate impairment in attention in RE. The Mirsky and Posner models of attention were evaluated for applicability, and studies were reviewed for design, instrumentation, and congruence with the Posner model of attention. RESULTS Fourteen studies were identified: seven using a cross-sectional design (six active EEG abnormalities; one EEG remission) and seven longitudinal studies (abnormal EEGs and follow-up until normalized). According to the Posner model of attention, 12 studies employed measures that tapped the alerting network, 11 studies the orienting network, and eight the executive network. Nearly all controlled studies demonstrated impairments in all tested attention networks. In contrast, uncontrolled studies uniformly did not demonstrate impairments. Follow-up studies demonstrated complete or near complete resolution of attention impairments. DISCUSSION The weight of evidence, defined as the majority of studies evaluated, suggests that all three attention systems are impaired in children with active centrotemporal spikes (CTS), implying a more widespread functional cortical disturbance in RE than previously held. These impairments resolve upon EEG remission, suggesting a common pathological basis to the autosomal dominant CTS trait. Sources of methodological variation are discussed with recommendations for future investigations.

Abstract
The immature brain may be particularly vulnerable to injury during critical periods of development. To address the biologic basis for this vulnerability, mice were subjected to traumatic brain injury at postnatal day 21, a time point that approximates that of the toddler-aged child. After motor and cognitive testing at either 2 weeks (juveniles) or 3 months (adults) after injury, animals were euthanized and the brains prepared for quantitative histologic assessment. Brain-injured mice exhibited hyperactivity and age-dependent anxiolysis. Cortical lesion volume and subcortical neuronal loss were greater in brain-injured adults than in juveniles. Importantly, cognitive decline was delayed in onset and coincided with loss of neurons in the hippocampus. Our findings demonstrate that trauma to the developing brain results in a prolonged period of pathogenesis in both cortical and subcortical structures. Behavioral changes are a likely consequence of regional-specific neuronal degeneration.

Abstract
Attention-deficit hyperactivity disorder (ADHD) in girls is a topic of growing research and clinical interest. For many years, girls with ADHD have been ignored and overshadowed by hyperkinetic and impulsive boys, but they are now attracting interest in an effort to understand the similarities and differences in the prevalence, symptoms, familial risk, comorbidities and treatment of ADHD in the two sexes. A review of past and current literature finds that the symptoms of ADHD are not sex specific, but that identification of girls with ADHD is hampered by parental and teacher bias, and confusion. Girls are more likely to be inattentive without being hyperactive or impulsive, compared with boys. Girls and boys share the same familial risk patterns, as well as similar, although not identical, comorbidity or impairment patterns. The risk of non-treatment is as great in girls as it is in boys; up to 70-80% of identified children will have persistent symptoms and impairment that extends into adolescence and adulthood. Treatment modalities are equally effective in girls and boys. Stimulants, non-stimulants and behavioural modalities are the mainstays of effective treatment.
