RESUMO

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.

RESUMO

Over the past 15 years, there have been significant advances in the treatment of acute and chronic medical consequences of stroke in childhood. Given high rates of survival in pediatric stroke, practitioners are tasked with treating the ongoing motor and neuropsychological sequelae in patients over the course of their development. This article provides a review of the current literature on neuropsychological outcomes in pediatric stroke, including intelligence, academics, language, visual-spatial skills, attention, executive functions, memory, and psychosocial function. Recent developments in functional neuroimaging are discussed, with a particular focus on language outcomes. We further review the current research on cognitive and behavioral rehabilitation and introduce intervention models in pediatric stroke. In the final section, we discuss future directions for clinical practice and research in pediatric stroke.

RESUMO

BACKGROUND: The pediatric stroke outcome measure (PSOM) is a standardized, disease-specific outcome measure. We aimed to validate the overall classification of neurological deficit severity using PSOM. METHODS: We identified 367 neonates/children with arterial ischemic stroke (AIS) (Derivation Cohort). We analyzed the PSOM subscales (scored as 0 [no deficit], 0.5 [minimal/mild deficit; normal function], 1 [moderate deficit; slowing function], or 2 [severe deficit; missing function]) to derive severity levels using latent class analysis (LCA). We validated a severity classification scheme (PSOM-SCS) in: (a) children who had Pediatric Evaluation of Disability Inventory (PEDI; n = 63) and/or the Pediatric Quality-of-Life Inventory (PedsQL; n = 97) scored; and (b) an external cohort (AIS; n = 102) with concurrently scored modified Rankin Scale (mRS), King's Outcome Scale for Childhood Head-Injury (KOSCHI) and PSOM. RESULTS: Within the Derivation Cohort, LCA identified three severity levels: "normal/mild," "moderate," and "severe" (83.7%, 13.3%, and 3%, respectively). We developed severity classification based on PSOM subscale scores: "normal/mild"-normal function in all domains or slowing in one domain, "moderate"-slowing in ≥2 domains or missing function in one domain, and "severe"-missing function in ≥2 domains or slowing in ≥1 plus missing in one domain. PEDI and PedsQL both differed significantly across the severity groups. PSOM-SCS displayed high concordance with mRS (agreement coefficient [AC2] = 0.88) and KOSCHI (AC2 = 0.79). CONCLUSION: The PSOM-SCS constitutes a valid tool for classifying overall neurological severity emphasizing function and encompassing the full range of severity in pediatric stroke. IMPACT: Arithmetic summing of the PSOM subscales scores to assess severity classification is inadequate.The prior severity classification using PSOM overestimates poor outcomes.Three distinct severity profiles using PSOM subscales are identified.The PSOM-SCS is in moderate to excellent agreement with other disability measures.PSOM-SCS offers a valid tool for classifying the overall neurological deficit severity.

RESUMO

AIM: To assess long-term cognitive function in children after cerebral sinovenous thrombosis (CSVT). METHOD: Children with CSVT, who had neuropsychological testing for intellectual ability, executive function, attention, language, or behavior, were included in a prospective observational study. Outcomes were compared with normative means using one-sample t-tests. Predictors of abnormal function were examined using logistic regression. RESULTS: Fifty children with CSVT were included (median age at diagnosis 2y 10mo, interquartile range 7d-6y 10mo; 35 males, 15 females). The median follow-up time was 4 years 2 months (interquartile range 2y 8mo-6y 4mo). Compared with normative means, children with CSVT had lower mean (± standard deviation) full-scale IQ, working memory, and processing speed scores (93.3±16, p=0.01; 93.6±16, p=0.04; 93.7±15.3, p=0.02 respectively). They also had lower scores in executive function, attention, and language domains. Refractory seizure at presentation was associated with a trend in behavioral problems (odds ratio [OR] 6.3, 95% confidence interval [CI] 0.9-46, p=0.07). Females were less likely to experience processing speed difficulties (OR 0.22, 95% CI 0.04-1.3, p=0.09). Incomplete recanalization was associated with a greater risk of abnormal verbal comprehension (OR 5.3, 95% CI 0.93-30.5, p=0.059). INTERPRETATION: Children with CSVT as a group performed below age expectations on standardized neuropsychological tests, although there was variability across individuals and cognitive domains. Larger studies are needed to evaluate predictors of cognitive deficits in children with CSVT.

RESUMO

OBJECTIVE: The Response to Stress Questionnaire-Brain Injury (RSQ-BI) was adapted utilizing a patient-oriented approach, exploring parental stress, coping, and associated mental health outcomes in parents of children with neonatal brain injury. The contributions of social risk, child adaptive functioning, and brain injury severity were also explored. METHODS: Using a mixed-method design, this study explored adapted stressor items on the RSQ-BI. Parents and clinicians engaged in semistructured interviews to examine key stressors specific to being a parent of a child with neonatal brain injury. The adapted RSQ-BI was piloted in a parent sample (N = 77, child mean age 1 year 7 months) with established questionnaires of social risk, child adaptive functioning, severity of the child's injury, coping style, and parent mental health. Descriptive statistics and correlations examined parent stress, coping, and their association with parent mental health. RESULTS: The final RSQ-BI questionnaire included 15 stressors. Factor analysis showed stressors loaded onto two factors related to (a) daily role stressors and (b) brain injury stressors. Using the RSQ-BI, parents reported brain injury stressors as more stressful than daily role stressors. When faced with these stressors, parents were most likely to engage in acceptance-based coping strategies and demonstrated lower symptoms of parent depression and anxiety. CONCLUSIONS: The RSQ-BI provides a valuable adaptation to understand both stressors and coping specific to being a parent of a child with neonatal brain injury. Relevant interventions that promote similar coping techniques are discussed for future care and research.

RESUMO

OBJECTIVES: The current study used a mixed-method design to qualitatively examine parents' definitions of resilience and factors they believed optimized their child's early outcome following neonatal brain injury. This was followed by quantitative analyses of early developmental and mental health outcomes and their relation to salient biopsychosocial factors. METHODS: Participants were parents of children diagnosed with neonatal brain injury due to stroke or hypoxic-ischemic encephalopathy (N=51; age range of children 18 months to 8 years). The Parent Experiences Questionnaire (PEQ) was used to qualitatively analyze parents' open-ended responses about their child's early experiences and outcome. The Child Behavior Checklist (CBCL) and Scales of Independent Behaviour Early Developmental Form (SIB-ED) parent ratings were used to measure child resilience from a quantitative perspective, identifying "at-risk" and "resilient" children using standard cutoffs. "Resilient" and "at-risk" children were compared on biopsychosocial variables using univariate t tests and chi-square analyses. RESULTS: Parents provided five unique definitions of their child's positive outcomes, and many children demonstrated resilience based on parent perspectives and quantitative definitions. Supporting factors included close medical follow-up, early intervention, and intrinsic factors within the child and parent. Group comparisons of "resilient" and "at-risk" children highlighted the importance of parent mental health across these early developmental and mental health outcomes. CONCLUSIONS: Many children were described as resilient during the early years by parents using qualitative and quantitative approaches. Findings highlighted the importance of parent well-being in promoting optimal early outcomes. (JINS, 2019, 25, 390-402.).

RESUMO

We report the neuropsychological profile of a 6-year-old girl with Wiskott-Aldrich syndrome, a rare X-linked immunodeficiency disorder associated with thrombocytopenia, eczema, recurrent infections, and malignancy. Wiskott-Aldrich syndrome occurs almost exclusively in males and is extremely rare in females, with no known research focused on cognitive and academic functioning in this population. Our patient was referred due to concerns about her memory and academic functioning. She had a history of progressive thrombocytopenia and hematopoietic stem cell transplantation at age 15 months. Standardized measures of intellectual ability, language, visual-spatial and visual-motor skills, attention, memory, and academic achievement were administered. The results showed average to above-average performance in multiple areas of cognitive and academic functioning, with weaknesses in phonological awareness and rapid naming. The advent of hematopoietic stem cell transplantation has led to considerable improvement in the long-term prognosis of children with Wiskott-Aldrich syndrome. Although the impact of this syndrome and related conditions on neurocognitive development is presently unknown, this case highlights both the importance of considering base rates for commonly occurring conditions and the significant role neuropsychology can play in identifying cognitive strengths and weaknesses in the context of the developing brain.

RESUMO

PRIMARY OBJECTIVE: This study aimed to create a specific questionnaire (Parent Experiences Questionnaire) about early experiences, service involvement, and needs of children and parents following neonatal brain injury that could be used to inform clinical care and needed interventions. RESEARCH DESIGN AND METHODS: A mixed-method design was utilized, engaging in both qualitative and quantitative methods across three phases. Phase 1 employed participatory design involving 12 parent and clinician participants in semi-structured interviews to address main topics, item importance, and overall impressions of the questionnaire. In phase 2, the questionnaire was piloted by 32 parents. Post hoc revisions added four questions to address current parent and child therapeutic needs in phase 3. MAIN OUTCOMES AND RESULTS: The final questionnaire yielded 24 items addressing topics of early communication between parent and clinicians, early intervention services, efficacy, and barriers in optimizing the child's development and parents' experience. The questionnaire was reviewed positively by a group of parents in phase 2 and demonstrated good acceptance, online feasibility, stability, and association with current parental mental health and child development. CONCLUSIONS: This investigation offers a valuable new questionnaire to inform clinical care regarding discussions with parents about neonatal brain injury, evaluate the perceived efficacy of early intervention services, and guide relevant future intervention efforts.

RESUMO

BACKGROUND: In this case series, functional magnetic resonance imaging was used to examine brain networks that mediate different aspects of language function in 4 young adults (17-22 years) with a history of left middle cerebral artery (MCA) stroke in childhood (40 years of age). Although it is widely believed that altered lateralization patterns are more likely to occur following early brain injuries compared with later brain injuries, the presumed plasticity of the young brain has been challenged in recent years, particularly in the domain of language. METHODS: We explored this issue by contrasting the brain activation patterns of individuals with childhood left MCA stroke and adult left MCA stroke while performing two language tasks: verb generation and picture-word matching. Importantly, both groups showed significant recovery of language function, based on standard clinical indicators. RESULTS: Controls showed left lateralized activation for both tasks, although much more pronounced for verb generation. Adult stroke patients also showed left lateralization for both tasks, though somewhat weaker than controls. Childhood stroke patients exhibited significantly weaker lateralization than the adult group for verb generation, but there was no significant group difference for picture-word matching. CONCLUSIONS: These preliminary findings suggest that successful reorganization of language function is more likely to involve bilateral recruitment following left MCA stroke in childhood than in adulthood. Of importance, although childhood stroke patients had primarily subcortical lesions, there were substantial alterations in cortical activation patterns.

RESUMO

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.

RESUMO

Pediatric stroke can result in long-term impairments across attention, functional communication and motor domains. The current paper utilized parent reports of the Behavioral Assessment System for Children 2nd Edition and the Pediatric Stroke Outcome Measure to examine children's social skills and withdrawal behavior within a pediatric stroke population. Using the Canadian Pediatric Stroke Registry at The Hospital for Sick Children, data were analyzed for 312 children with ischemic stroke. Children with ischemic stroke demonstrated elevated parent-reported social skills problems (observed = 20.51%, expected = 14.00%) and clinically elevated social withdrawal (observed = 11.21%, expected = 2.00%). Attentional problems significantly contributed to reduced social skills, F (3,164) = 30.68, p < 0.01, while attentional problems and neurological impairments accounted for increased withdrawal behavior, F (2, 164) = 7.47, p < 0.01. The presence of a motor impairment was associated with higher social withdrawal compared to individuals with no motor impairment diagnosis, t(307.73) = 2.25, p < .025, d = 0.25, 95% CI [0.42, 6.21]. The current study demonstrates that children with stroke who experience motor impairments, attentional problems, reduced functional communication skills, and neurological impairments can experience deficits in their social skills and withdrawal behavior.

RESUMO

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.

RESUMO

Aim: Although many children who experience ischemic stroke come from bilingual backgrounds, it is unclear whether bilingual exposure affects poststroke development. Our research evaluates bilingual and monolingual exposure on linguistic/cognitive development poststroke across 3 stroke-onset groups. Method: An institutional stroke registry and medical charts were used to gather data on 237 children across 3 stroke-onset groups: neonatal, <28 days; first-year, 28 days to 12 months; and childhood, 13 months to 18 years. The Pediatric Stroke Outcome Measure (PSOM), administered several times poststroke, was used to evaluate cognition and linguistic development. Results: Similar cognitive outcomes were observed across language groups. However, an interaction effect with stroke-onset group was observed, with monolinguals in the first-year group having worse productive language outcomes as compared to bilinguals. Interpretation: Overall, no detrimental effects of bilingualism were found on children's poststroke cognition and linguistic development. Our study suggests that a bilingual environment may facilitate language development in children poststroke.

RESUMO

Following a pediatric stroke, outcome measures selected for monitoring functional recovery and development vary widely. We sought to develop a toolkit of outcome measures that are currently available to clinicians, possess strong psychometric properties, and are feasible for use within clinical settings. A multidisciplinary group of clinicians and scientists from the International Pediatric Stroke Organization comprehensively reviewed the quality of measures in multiple domains described in pediatric stroke populations including global performance, motor and cognitive function, language, quality of life, and behavior and adaptive functioning. The quality of each measure was evaluated using guidelines focused on responsiveness and sensitivity, reliability, validity, feasibility, and predictive utility. A total of 48 outcome measures were included and were rated by experts based on the available evidence within the literature supporting the strengths of their psychometric properties and practical use. Only three measures were found to be validated for use in pediatric stroke: the Pediatric Stroke Outcome Measure, the Pediatric Stroke Recurrence and Recovery Questionnaire, and the Pediatric Stroke Quality of Life Measure. However, multiple additional measures were deemed to have good psychometric properties and acceptable utility for assessing pediatric stroke outcomes. Strengths and weaknesses of commonly used measures including feasibility are highlighted to guide evidence-based and practicable outcome measure selection. Improving the coherence of outcome assessment will facilitate comparison of studies and enhance research and clinical care in children with stroke. Further work is urgently needed to close the gap and validate measures across all clinically significant domains in the pediatric stroke population.

RESUMO

BACKGROUND AND PURPOSE: The Pediatric Stroke Outcome Measure (PSOM) is an objective, disease-specific outcome measure containing 115 test items suitable for newborn to adult ages. The PSOM measures neurological deficit and function across 5 subscales: right sensorimotor, left sensorimotor, language production, language comprehension, and cognitive/behavior yielding a final 10-point deficit score. The goal of this study was to examine PSOM construct validity in measuring neurological outcome in pediatric stroke survivors and interrater reliability (IRR) for both prospective and retrospective scoring. METHODS: For construct validity, PSOM subscale scores were correlated with scores on standardized neuropsychological measures matched by functional domain. We assessed IRR by comparing same-day "live" PSOM scores from 2 independent raters in 10 children (prospective IRR) and by comparing PSOM scores estimated from medical dictations across 5 raters in another 10 children (retrospective IRR). RESULTS: We analyzed PSOM scores from 203 children with ischemic stroke. PSOM subscales show good construct validity (ρ=0.2-0.4; P<0.05). PSOM subscale scores of normal/abnormal demonstrate strong agreement for domain-matched neuropsychology scores (alternative chance-corrected statistic=0.4-0.8). IRR was excellent with the 2 prospective raters' scores in almost perfect agreement (intraclass correlation coefficient, 0.93; 95% CI, 0.76-0.98). Retrospective IRR demonstrated strong agreement with an intraclass correlation coefficient of 0.77 (95% CI, 0.56-0.92). CONCLUSIONS: The PSOM is a valid and reliable outcome measure for pediatric stroke. It is useful for retrospective scoring from health records and prospective serial longitudinal outcome assessments and is ideally suited for prospective clinical trials in pediatric stroke.

RESUMO

AIM: Moyamoya vasculopathy is characterized by progressive stenosis of the major arteries of the Circle of Willis, resulting in compromised cerebral blood flow and increased risk of stroke. The objectives of the current study were to examine intellectual and executive functioning of children with moyamoya and to evaluate the impact of moyamoya type, stroke (clinical or silent), vasculopathy laterality, and disease duration on neurocognitive abilities. METHOD: Thirty pediatric participants (mean age 10 y 10 mo, SD 4 y; 18 females, 12 males) completed age-appropriate Wechsler Intelligence Scales before any therapeutic revascularization procedures. Reports of executive function were obtained from parents and teachers using the Behavior Rating Index of Executive Function. RESULTS: Children with moyamoya scored significantly lower than the test standardization samples on all indices of intelligence and ratings of executive functioning (p<0.001). Patients did not differ by type of moyamoya or history of stroke. Patients with bilateral disease and stroke scored significantly lower than those with unilateral disease on measures of overall intellectual function (p=0.035) and verbal comprehension (p=0.04). Deficits in metacognitive executive functions were also more pronounced in bilateral patients according to teacher ratings. INTERPRETATION: Children with moyamoya are at risk for intellectual and executive problems, exacerbated by bilateral disease and clinical stroke history.

RESUMO

The current study examined the utility of the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) in capturing emerging deficits in executive function in preschool children with a history of perinatal stroke. Parents and teachers of 55 clinically referred preschool children (3-5 years of age) provided ratings using the BRIEF-P. Both parent (M = 56.02, p = .001) and teacher ratings (M = 58.61, p = .002) indicated significant scale elevations for working memory compared to the normative sample, albeit below the clinically elevated range. Parent and teacher ratings were low-to-moderately correlated (r = .05-.55). Greater deficits in working memory (r = -.58), inhibition (r = -.45), and planning/organization (r = -.51), as rated by teachers, were associated with lower intellectual functioning. Parents' ratings were not associated with intellectual functioning. Further, no neurological or personal characteristics were associated with ratings of executive function. The current study demonstrates children with a history of perinatal stroke are, on average, following a normal trajectory of executive function development according to BRIEF-P ratings. The needs for multi-informant ratings and performance-based measures to comprehensively assess executive functioning in preschoolers with a history of stroke are discussed.

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.

RESUMO

Understanding how pediatric neuropsychological evaluations support families and the child's medical team is an important component of ensuring evidence-based care. For the first time within a Canadian context, we investigated the impact of neuropsychological assessments on parent knowledge, advocacy, and stress and the role of socioeconomic factors in parents' perceptions of the assessment. Responses from referring clinicians were also examined. As part of a hospital quality improvement project, 91 parents of children between the ages of 3 and 17 years (M = 8y7m; SD = 4y1m) and 45 clinician consumers (clinical staff who use neuropsychological services) completed one of two online questionnaires in English: Parent Overall Assessment of Supports and Testing, or Clinician Overall Assessment of Supports and Testing. Most parents indicated the neuropsychological evaluation promoted understanding of their child's cognitive profile and improved their ability to support their child at home and at school or in the community. Families characterized as being at higher social risk indicated that the evaluation led to more changes in how they approached their child at home than families with lower social risk status. Referring clinicians indicated neuropsychological reports were effective in communicating findings to them and patients/families. The most valuable sections of the report according to referring clinicians included the diagnosis/impression and recommendations sections. Parents and referral providers reported many benefits from the neuropsychological evaluation but also identified areas for service delivery improvement. Parent perceptions varied based on family and socio environmental factors, offering important targets for future research and clinical consideration.
