Abstract
Objective Dystonia is a movement disorder defined by involuntary muscle contractions leading to abnormal postures or twisting and repetitive movements. Classically dystonia has been thought of as a disorder of the basal ganglia, but newer results in idiopathic dystonia and lesion-induced dystonia in adults point to broader motor network dysfunction spanning the basal ganglia, cerebellum, premotor cortex, sensorimotor, and frontoparietal regions. It is unclear whether a similar network is shared between different etiologies of pediatric lesion-induced dystonia. Methods Three cohorts of pediatric patients with lesion-induced dystonia were identified. The lesion etiologies included hypoxia, kernicterus, and stroke versus comparison subjects with acquired lesions not associated with dystonia. Multivariate lesion-symptom mapping and lesion network mapping were used to evaluate the anatomy and networks associated with dystonia. Results Multivariate lesion-symptom mapping showed that lesions of the putamen (stroke: r = 0.50, p <0.01; hypoxia, r = 0.64, p <0.001) and globus pallidus (kernicterus, r = 0.61, p <0.01) were associated with dystonia. Lesion network mapping using normative connectome data from healthy children demonstrated that these regional findings occurred within a common brain-wide network that involves the basal ganglia, anterior and medial cerebellum, and cortical regions that overlap the cingulo-opercular and somato-cognitive-action networks. Interpretation We interpret these findings as novel evidence for a unified dystonia brain network that involves the somato-cognitive-action network, which is involved in higher order coordination of movement. Elucidation of this network gives insight into the functional origins of dystonia and provides novel targets to investigate for therapeutic intervention.

Abstract
BACKGROUND Current studies on the impact of sex in the prognosis of childhood arterial ischemic stroke (AIS) are limited. We aimed to explore the sex differences in outcomes in patients with childhood AIS. METHODS A retrospective analysis was conducted using the prospective data from the Chinese Pediatric Ischemic Stroke Registry. Baseline characteristics between sexes were compared in the total population cohort, propensity score (PS)-matched cohort, and inverse probability of treatment weighting cohort. Multivariate logistic regression and ordinal regression were used to analyze the association of sex with outcomes. Mixed-effects regression model was applied to further analyze the improvement in pediatric modified Rankin Scale (mRS) scores between sexes from 90 days to one year. Survival analysis was used to estimate the recurrence rates during the follow-up period. RESULTS A total of 468 patients were finally included. Multivariate logistic regression showed that there were no significant differences between females and males in achieving favorable outcome (odds ratio [OR] 1.04, 95% confidence interval [CI] 0.63 to 1.72), functional independence (OR 0.98, 95% CI 0.59 to 1.63), or shift to worse pediatric mRS scores (OR 0.83, 95% CI 0.59 to 1.17) at 90-day. Mixed-effects regression and survival analysis indicated that females and males exhibited comparable functional recovery from 90 days to one year and had similar recurrent risk during the follow-up period. CONCLUSIONS This nationally-representative observational study indicated that both male and female pediatric patients with AIS exhibited comparable similar clinical outcomes at 90 days, as well as similar improvements and risks of recurrence during the follow-up period.

Abstract
PURPOSE OF REVIEW Neurological problems are common in infants admitted to the neonatal intensive care unit (NICU). Various neuroimaging modalities are available for neonatal brain imaging and are selected based on presenting problem, timing and patient stability. RECENT FINDINGS Neuroimaging findings, taken together with clinical factors and serial neurological examination can be used to predict future neurodevelopmental outcomes. In this narrative review, we discuss neonatal neuroimaging modalities, and how these can be optimally utilized to assess infants in the NICU. We will review common patterns of brain injury and neurodevelopmental outcomes in hypoxic-ischemic encephalopathy, perinatal arterial ischemic stroke and preterm brain injury. SUMMARY Timely and accurate neuroprognostication can identify infants at risk for neurodevelopmental impairment and allow for early intervention and targeted therapies to improve outcomes.

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
To assess the association between clinical and MRI characteristics of arterial ischaemic stroke (AIS) and the 3-year risk of post-stroke epilepsy (PSE) in paediatric patients. Retrospective cohort study. Database from a single tertiary referral centre for paediatric stroke in Chile. Two hundred seven neonates and children (1 day to 18 years) with a first-ever supratentorial AIS diagnosed between January 2003 and December 2019 were evaluated. Diagnosis of PSE and explanatory variables were consecutively recorded from hospital inpatient and annual outpatient records in a predesigned database. Competing risk analysis (competing events: death and loss to follow-up) of multiple Cox proportional hazards regression was performed to estimate adjusted subhazard ratios (SHRs) of PSE. Confidence intervals (95% CI) were calculated using bootstrap resampling (1000 replications). Interaction terms were added to investigate moderating effects. The 3-year incidence rate of PSE was 166.5 per 1000 person-years (neonatal: 150.1; childhood: 173.9). The 3-year cumulative incidence was 33%. Patients with acute symptomatic non-status seizures (SHR = 3.13; 95% CI = 1.43-6.82), status epilepticus (SHR = 5.16; 95% CI = 1.90-13.96), abnormal discharge neurological status (SHR = 2.52; 95% CI = 1.12-5.63), cortical lesions (SHR = 2.93; 95% CI = 1.48-5.81), and multifocal infarcts with stroke size < 5% of supratentorial brain volume (SHR = 3.49; 95% CI = 1.44-8.46) had a higher risk of PSE. CONCLUSION This study identified specific and reliable acute clinical and imaging predictors of PSE in paediatric patients, helping clinicians identify high-risk patients with potential implications for treatment decisions. WHAT IS KNOWN • Numerous risk factors have been proposed for post-stroke epilepsy, but there is a lack of studies evaluating these variables while accounting for confounding factors and competing risks over time. WHAT IS NEW • After adjustment for competing events, acute symptomatic seizures, both non-status and status epilepticus, abnormal mental status or motor neurological examination at hospital discharge, cortical involvement, and multifocal ischaemic lesions in small strokes are all independent predictors of post-stroke epilepsy. • Knowing the predictors of post-stroke epilepsy is essential for clinicians to make well-informed and effective decisions about treatment.

Abstract
Pediatric stroke (PS) is an injury caused by the occlusion or rupture of a blood vessel in the central nervous system (CNS) of children, before or after birth. Hemiparesis is the most common motoric deficit associated with PS in children. Therefore, it is important to emphasize that PS is a significant challenge for rehabilitation, especially since the consequences may also appear during the child's growth and development, reducing functional capacity. The plasticity of the child's CNS is an important predecessor of recovery, but disruption of the neural network, specific to an immature brain, can have harmful and potentially devastating consequences. In this review, we summarize the complexity of the consequences associated with PS and the possibilities and role of modern rehabilitation. An analysis of the current literature reveals that Constraint-Induced Movement Therapy, forced-use therapy, repetitive transcranial magnetic stimulation, functional electrical stimulation and robot-assisted therapy have demonstrated at least partial improvements in motor domains related to hemiparesis or hemiplegia caused by PS, but they are supported with different levels of evidence. Due to the lack of randomized controlled studies, the optimal rehabilitation treatment is still debatable, and therefore, most recommendations are primarily based on expert consensuses, opinions and an insufficient level of evidence.

Abstract
To delineate prevalence of stroke in the pediatric intensive care unit and to determine risk factors for stroke and association of stroke with mortality in patients with congenital heart disease. Retrospective cohort study. Patients admitted to pediatric intensive care units in the USA participating in the Pediatric Health Information System database from 2016 to 2021. Patients were categorized as those who experienced ischemic or hemorrhagic stroke and those with congenital heart disease. We performed univariate and multivariate logistic regressions to determine risk factors associated with stroke and then developed a predictive model for stroke development in patients with congenital heart disease. Of 426,029 admissions analyzed, 4237 (0.9%) patients experienced stroke and 1197 (1.4%) of 80,927 patients with congenital heart disease developed stroke (odds ratio 1.15, 95% confidence interval 1.06-1.24). Patients with congenital heart disease, younger age, extracorporeal membrane oxygenation, mechanical ventilation, and cardiac arrest were most strongly associated with increased risk of stroke. Stroke increased odds of mortality for patients with congenital heart disease (odds ratio 2.49, 95% confidence interval 2.08-2.98). A risk score greater than 0 was associated with a 33.3% risk of stroke for patients with congenital heart disease (negative predictive value of 99%, sensitivity 69%, specificity 63%). Children with congenital heart disease are at increased risk for developing stroke, which is associated with increased mortality. Early identification of the most vulnerable patients may enable providers to implement preventative measures or rapid treatment strategies to prevent neurologic morbidity.

Abstract
BACKGROUND Perinatal arterial ischemic stroke (PAIS) is a neurologic disorder leading to long-term complications. Mesenchymal stem cells (MSCs) have emerged as a novel therapeutic agent. This systematic review aims to determine the effects of stem cell-based interventions for the treatment of PAIS in preclinical studies. METHODS We included all controlled studies on MSCs in neonatal animals with PAIS. Functional outcome was the primary outcome. The literature search was performed in February 2021. RESULTS In the 20 included studies, MSCs were most frequently delivered via intracerebral injection (n = 9), 3 days after the induction of PAIS (n = 8), at a dose ranging from 5 × 104 to 5 × 106 cells. The meta-analysis showed an improvement on the cylinder rearing test (MD: -10.62; 95% CI: -14.38 to -6.86) and on the water maze test (MD: 1.31 MD; 95% CI: 0.80 to 1.81) in animals treated with MSCs compared to the control group animals. CONCLUSION MSCs appear to improve sensorimotor and cognitive performance in PAIS-injured animals; however, the certainty of the evidence is low. Registration of the protocol of preclinical studies, appropriate sample size calculation, rigorous randomization, and reporting of the data on animal sex and survival are warranted. PROSPERO registration number: CRD42021239642. IMPACT This is the first systematic review and meta-analysis of preclinical studies investigating the effects of MSCs in an experimental model of PAIS. MSCs appear to improve sensorimotor and cognitive performance in PAIS-injured neonatal animals. The certainty of the evidence is low due to high or unclear risk of bias in most domains.

Abstract
PURPOSE OF REVIEW The purpose of this paper is to review recent updates in the acute management of childhood arterial ischemic stroke, including reperfusion therapies and neuroprotective measures. RECENT FINDINGS With the emergence of pediatric stroke centers in recent years, processes facilitating rapid diagnosis and treatment have resulted in improved implementation of early targeted neuroprotective measures as well as the increased use of reperfusion therapies in childhood arterial ischemic stroke. Retrospective data has demonstrated that alteplase is safe in carefully selected children with arterial ischemic stroke in the first 4.5 h from symptom onset, though data regarding its efficacy in children are still lacking. There is also increasing data that suggests that thrombectomy in children with large vessel occlusion improves functional outcomes. Recent adult studies, including the use of Tenecteplase as an alteplase alternative and expansion of late thrombectomy to include patients with large ischemic cores, also are reviewed along with limitations to application of the adult data to pediatric care. SUMMARY There have been significant advances in the hyperacute care of children with ischemic stroke and early diagnosis and targeted management are of the upmost importance in improving long-term outcomes.

We undertook an updated systematic review and meta-analysis of endovascular thrombectomy in children and compared their outcomes with adult data. METHODS We searched PubMed, Medline, and EMBASE databases to identify prospective and retrospective studies describing patients <18 years treated with endovascular thrombectomy for acute ischemic stroke due to large-vessel occlusion. RESULTS Eight pediatric studies were included (n = 192). Most patients were male (53.1 %), experienced anterior circulation large-vessel occlusion (81.8 %), and underwent endovascular thrombectomy by stent retreiver (70.7 %). The primary outcome was change in National Institutes of Health Stroke Scale score from presentation to 24 h after thrombectomy. Secondary outcomes included modified Rankin scale score improvement and 90-day score, recanalization rates, procedural complications, and mortality rates. After treatment, 88.5% of children had successful recanalization; the mean National Institutes of Health Stroke Scale score reduction was 7.37 (95 % CI 5.11-9.63, p < 0.01). The mean reduction of 6.87 (95 %CI 5.00-8.73, p < 0.01) for adults in 5 clinical trials (n = 634) was similar (Qb = 0.11; p = 0.74). Children experienced higher rates of good neurological outcome (76.1 % vs. 46.0 %, p < 0.01) and revascularization (88.5 % vs. 72.3 %, p < 0.01), fewer major periprocedural complications (3.6 % vs. 30.4 %, p < 0.01), and lower mortality (1.0 % vs. 12.9 %, p < 0.01). CONCLUSIONS Endovascular thrombectomy may be safe and effective treatment for acute ischemic stroke due to large-vessel occlusion in children. The aggregated data demonstrated high rates of revascularization, favorable long-term neurological outcomes, and low complication rates.

Abstract
BACKGROUND Neonatal stroke manifests atypically and can potentially result in significant neurological sequelae in affected infants. Studies on long-term neurodevelopmental outcomes and prognostic factors are limited. We aimed to assess the clinical characteristics, long-term outcomes, and prognostic factors of perinatal stroke. METHODS Patients diagnosed with perinatal stroke were enrolled from 2009 to 2018. Clinical data including general information, clinical manifestations, and risk factors were collected and compared. Follow-up was performed for at least two years. Statistical analysis was performed using the chi-square test, t tests, and logistic regression analysis. RESULTS Sixty-nine cases were identified with an incidence of one of 2049 live births (51 boys and 18 girls). Twenty-seven patients (39%) experienced perinatal ischemic stroke (PIS) and 42 (61%) perinatal hemorrhagic stroke (PHS). In 48 cases (69%) onset involved acute symptomatic stroke (21 ischemic strokes and 27 hemorrhagic strokes). Seizures within 12 to 72 hours (20 cases, 29%) were the most common presentations. Most (57%) perinatal arterial ischemic strokes focused on the left middle cerebral artery. About 43% of PHS was diagnosed with temporal lobe hemorrhage, and 40% of patients exhibited multiple lesions of cerebral parenchymal hemorrhage. There was no association between adverse prognosis after perinatal stroke and different risk factors. During follow-up, six patients (10%) were dead and 22 patients (35%) experienced adverse neurodevelopmental outcomes. CONCLUSIONS More infants exhibited hemorrhagic stroke than ischemic stroke. Among infants with asymptomatic perinatal stroke, PHS was more common. The first symptom of perinatal stroke within 12 to 72 hours after birth is convulsions, with the left middle cerebral artery and the temporal lobe being the most common lesion sites for ischemic and hemorrhagic strokes, respectively. PIS was more likely to achieve adverse outcomes.

Abstract
Background Epilepsy is one of the most serious consequences of perinatal stroke. Epilepsy itself has been proposed as a risk factor for impaired cognitive, language, and behavioral functioning. It is still unclear which children develop epilepsy after perinatal stroke. The current study aimed to evaluate the volume of the thalamus and the basal ganglia in children after perinatal stroke in relation to poststroke epilepsy. Methods The follow-up study included 29 children with perinatal arterial ischemic stroke (AIS), 33 children with presumed periventricular venous infarction (PVI), and 46 age- and sex-matched healthy controls. Magnetic resonance imaging was performed in children between the ages of 4 and 18 years, and volumetric analysis by segmentation was used to evaluate the size of the thalamus, caudate nucleus, putamen, globus pallidus, hippocampus, amygdala, and nucleus accumbens. Results During a median follow-up time of 12.8 years [interquartile range (IQR): 10.8-17.3] in the AIS group and 12.5 years (IQR: 9.3-14.8) in the PVI group (p = 0.32), epilepsy developed in 10 children (34.5%) with AIS and in 4 (12.1%) children with PVI, p = 0.036 [odds ratio (OR) = 3.8, 95%, confidence interval (CI): 1.04-14]. Epilepsy and interictal epileptiform discharges (IEDs) without clinical seizures were more often expressed in children with AIS (n = 16, 55%) than in children with PVI (n = 7, 21.2%), p = 0.0057 (OR = 3.8 95% CI: 1.04-14). In the AIS group, the ipsilesional and contralesional thalamus, ipsilesional caudate nucleus, and nucleus accumbens were significantly smaller in children with epilepsy compared to children without epilepsy. In the PVI group, the ipsilesional thalamus, caudate nucleus, and nucleus accumbens were smaller in the pooled group of epilepsy plus IED alone compared to children without epilepsy. Conclusion In children with AIS, epilepsy or IED occurred more often compared to children with PVI. Both patients with AIS and PVI with severe damage to the basal ganglia and the thalamus have a higher risk of developing poststroke epilepsy and should be monitored more closely throughout childhood to initiate timely antiseizure medication and rehabilitation.

Abstract
Coronavirus disease 2019 (COVID-19) associated coagulopathy is multifactorial and involves inflammation driven hypercoagulability, endothelial dysfunction, platelet activation, and impaired fibrinolysis. Hospitalized adults with COVID-19 are at an increased risk of both venous thromboembolism and ischemic stroke, resulting in adverse outcomes, including increased mortality. Although COVID-19 in children follows a less severe course, both arterial and venous thromboses have been reported in hospitalized children with COVID-19. Additionally, some children develop a postinfectious, hyperinflammatory illness termed multisystem inflammatory syndrome of childhood (MIS-C), which is also associated with hypercoagulability and thrombosis. Several randomized trials have evaluated the safety and efficacy of antithrombotic therapy in adults with COVID-19, although similar pediatric data are lacking. In this narrative review, we discuss the postulated pathophysiology of COVID-19 coagulopathy and summarize principal findings of the recently completed adult trials of antithrombotic therapy. We provide an up-to-date summary of pediatric studies investigating the rate of venous thromboembolism and ischemic stroke in COVID-19 and multisystem inflammatory syndrome of childhood in addition to reviewing the findings of the single, nonrandomized pediatric trial investigating the safety of prophylactic anticoagulation. Lastly, we outline adult and pediatric consensus guidelines on the use of antithrombotic therapy in this cohort. A detailed discussion of the practical implementation and current limitations of published data will hopefully address the knowledge deficits surrounding the use of antithrombotic therapy in children with COVID-19 and generate hypotheses for future research.

Abstract
AIM We investigated the prevalence of seizures in term-born infants with a perinatal stroke in Swedish neonatal wards, assessed the anti-seizure medication prescribed and determined the accuracy of diagnostic codes. METHODS This cross-sectional study used data from the Swedish Neonatal Quality Register. The cases were infants born at ≥37 weeks in 2009-2018 and admitted to a neonatal ward in Stockholm County with a stroke diagnosis, confirmed by their medical chart. The controls were all Swedish infants born during those years. RESULTS There were 76 infants with a confirmed perinatal stroke: 51 ischaemic and 25 haemorrhagic. Seizures were documented in 66/76 (87%) of infants with a stroke and 0.2% of the controls. Anti-seizure medication was administered to 64/66 (97%) infants with a stroke and seizures. In 60 cases, the drugs administered were specified, with phenobarbital used in 59/60 cases (98%). More than one drug was administered to 25/60 (42%) infants and 31/60 (52%) were discharged with anti-seizure medication. The positive predictive value for the stroke diagnostic codes was 80.5% (95% CI 76.5-84.5). CONCLUSION Seizures were common in infants with a perinatal stroke. More than one anti-seizure drug was often required and many infants were on anti-seizure medication at discharge, against Swedish recommendations.

Abstract
Pediatric strokes are infrequent yet impactful occurrences with distinct challenges due to their unique pathophysiology and diagnostic complexities. Antiphospholipid syndrome, an autoimmune disorder characterized by antiphospholipid antibodies, can lead to prothrombotic states causing vascular occlusions. Here, we present the case of a previously healthy two-year-old girl who presented with sudden right-sided hemiparesis and altered consciousness. Comprehensive assessments and evaluations revealed a diagnosis of a massive left middle cerebral artery ischemic stroke secondary to antiphospholipid syndrome. The patient received intensive care, antiplatelet therapy, and supportive measures. Gradual improvement in neurological status and motor skills was observed during hospitalization, and the patient underwent comprehensive rehabilitation. This case emphasizes the importance of vigilance, thorough diagnostic evaluation, and tailored treatment strategies. Anticoagulation therapy plays a pivotal role, necessitating a delicate balance between thrombosis prevention and bleeding risk. The significance of multidisciplinary approaches and specialized care for pediatric stroke cases is underscored.

Abstract
BACKGROUND We aimed to examine inherited thrombophilia frequencies by extending genetic profile to previously rarely or not investigated polymorphisms in children with ischemic pediatric stroke (IPS) and their parents. METHODS The study included 33 children: 23 with perinatal arterial ischemic stroke (PAIS), eight with childhood arterial ischemic stroke (CAIS), and two with sinovenous thrombosis and their parents (33 mother-child, 12 father-child, and 12 mother-father-child pairs). Genotyping of FV-Leiden, FV-H1299R, FII-G20210A, β-fibrinogen-455G>A, FXIII-A-Val34Leu, PAI-1(4G/5G), HPA-1, MTHFR-C677T, MTHFR-A1298C, ACE(I/D), and APOE(ε2-4) was performed using CVD Strip assay (ViennaLab, Austria). RESULTS At least one and up to seven simultaneously present polymorphisms were observed in all children with IPS, mothers, and fathers. More than five simultaneously present polymorphisms were identified threefold more frequently in children with IPS (10 of 33; 30%) compared with the child control group (17 of 150; 11%), yielding a statistically significant difference between the two groups (odds ratio [OR] = 3.40; 95% confidence interval [CI] = 1.39 to 8.35; P = 0.012). Stronger association was revealed for PAIS (OR = 4.17; 95% CI = 1.55 to 11.29; P = 0.008) and CAIS subgroups (OR = 7.82; 95% CI = 1.79 to 34.20; P = 0.012). Complete match of polymorphisms was not identified in any parent-child pair. A partial match (one to four mutual polymorphisms) was found in 11 of 12 parent-child pairs where until three mutual polymorphisms was present in 11 of 12 (91.7%) father-child compared with 21 of 33 (63.6%) mother-child pairs. CONCLUSIONS According to obtained results the simultaneous presence of more than five polymorphisms is associated with a higher risk for IPS occurrence, suggesting the risk enhancement for PAIS in the presence of pregnancy complications or for CAIS in conjunction with maternal comorbidity and positive family history. The presence of up to three mutual polymorphisms more frequently in father-child than mother-child pairs suggests significant paternal contribution of inherited thrombophilia to increased risk of IPS.

Abstract
(1) Background: Celiac disease (CD) can cause long-term inflammation and endothelial dysfunction and has been cited as a risk factor for acute ischemic stroke (AIS) in pediatric patients. However, the rate and outcomes of AIS in pediatric patients with CD has not been explored in a large population. Our objective is to explore the rate, severity, and outcomes of CD amongst pediatric AIS patients on a nationwide level. (2) Methods: The National Inpatient Sample (NIS) database was queried from 2016 to 2020 for pediatric patients with a principal diagnosis of AIS. Patients with a concurrent diagnosis of CD (AIS-CD) were compared to those without (AIS). Baseline demographics and comorbidities, clinical variables of severity, hospital complications, and the rates of tissue plasminogen activator (tPA) and mechanical thrombectomy were compared between the two groups. The main outcomes studied were mortality, discharge disposition, length of stay (LOS), and total hospital charges. (3) Results: Of 12,755 pediatric patients with a principal diagnosis of AIS, 75 (0.6%) had concurrent CD. There were no differences in the severity, discharge disposition, or mortality between the AIS-CD and AIS patients. Patients with AIS-CD were more likely to receive tPA at an outside hospital within 24 h of admission (p < 0.01) and more likely to undergo mechanical thrombectomy (p < 0.01) compared to the AIS patients. (4) Conclusions: CD patients made up only 0.6% of all pediatric AIS patients. No differences in the severity, mortality, or discharge disposition suggests a minimal to absent role of CD in the etiology of stroke. The CD-AIS patients were more likely to receive a tPA or undergo a mechanical thrombectomy; studies are needed to confirm the safety and efficacy of these interventions in pediatric patients.

Abstract
Background This retrospective cohort study aimed to examine the positive predictive value (PPV) of pediatric stroke diagnoses in the Danish National Registry of Patients (DNRP) and the impact of different stroke definitions on the PPV. Methods We included children registered with a stroke or stroke-related diagnosis in the DNRP between January 2017 through December 2020. Two assessors reviewed medical records and validated cases according to the American Heart and American Stroke Association (AHA/ASA) stroke definition. The level of interrater agreement was examined using kappa statistics. Validation by the AHA/ASA definition was compared with validation according to the definition in the International Classification of Disease 11th version (ICD-11) and the World Health Organization's definition. Results Stroke was confirmed in 120 of 309 included children, yielding an overall PPV of 0.39 (95% CI: 0.33-0.45). PPV varied across stroke subtypes from 0.83 (95% CI: 0.71-0.92) for ischemic stroke (AIS), 0.57 (95% CI: 0.37-0.76) for unspecified stroke, 0.42 (95% CI: 0.33-0.52) for intracerebral hemorrhage (ICH) to 0.31 (95% CI: 0.55-0.98) and 0.07 (95% CI: 0.01-0.22) for cerebral venous thrombosis and subarachnoid hemorrhage (SAH), respectively. Most non-confirmed ICH and SAH diagnoses were in children with traumatic intracranial hemorrhages (36 and 66% respectively). Among 70 confirmed AIS cases, 25 (36%) were identified in non-AIS code groups. PPV varied significantly across stroke definitions with the highest for the AHA/ASA definition (PPV = 0.39, 95% CI: 0.34-0.45) and the lowest for the WHO definition (PPV = 0.29, 95% CI: 0.24-0.34). Correspondingly, the incidence of pediatric AIS per 100.000 person-years changed from 1.5 for the AHA/ASA definition to 1.2 for ICD-11 and 1.0 for the WHO-definition. The overall interrater agreement was considered excellent (κ=0.85). Conclusion After validation, stroke was confirmed in only half of the children registered in the DNRP with a stroke-specific diagnosis. Non-validated administrative data should be used with caution in pediatric stroke research. Pediatric stroke incidence rates may vary markedly depending on which stroke definition is used.

Abstract
Childhood stroke occurs from birth to 18 years of age, ranks among the top ten childhood causes of death, and leaves lifelong neurological impairments. Arterial ischemic stroke in infancy and childhood occurs due to arterial occlusion in the brain, resulting in a focal lesion. Our understanding of mechanisms of injury and repair associated with focal injury in the developing brain remains rudimentary. Neuroimaging can reveal important insights into these mechanisms. In adult stroke population, multi-center neuroimaging studies are common and have accelerated the translation process leading to improvements in treatment and outcome. These studies are centered on the growing evidence that neuroimaging measures and other biomarkers (e.g., from blood and cerebrospinal fluid) can enhance our understanding of mechanisms of risk and injury and be used as complementary outcome markers. These factors have yet to be studied in pediatric stroke because most neuroimaging studies in this population have been conducted in single-centred, small cohorts. By pooling neuroimaging data across multiple sites, larger cohorts of patients can significantly boost study feasibility and power in elucidating mechanisms of brain injury, repair and outcomes. These aims are particularly relevant in pediatric stroke because of the decreased incidence rates and the lack of mechanism-targeted trials. Toward these aims, we developed the Pediatric Stroke Neuroimaging Platform (PEDSNIP) in 2015, funded by The Brain Canada Platform Support Grant, to focus on three identified neuroimaging priorities. These were: developing and harmonizing multisite clinical protocols, creating the infrastructure and methods to import, store and organize the large clinical neuroimaging dataset from multiple sites through the International Pediatric Stroke Study (IPSS), and enabling central searchability. To do this, developed a two-pronged approach that included building 1) A Clinical-MRI Data Repository (standard of care imaging) linked to clinical data and longitudinal outcomes and 2) A Research-MRI neuroimaging data set acquired through our extensive collaborative, multi-center, multidisciplinary network. This dataset was collected prospectively in eight North American centers to test the feasibility and implementation of harmonized advanced Research-MRI, with the addition of clinical information, genetic and proteomic studies, in a cohort of children presenting with acute ischemic stroke. Here we describe the process that enabled the development of PEDSNIP built to provide the infrastructure to support neuroimaging research priorities in pediatric stroke. Having built this Platform, we are now able to utilize the largest neuroimaging and clinical data pool on pediatric stroke data worldwide to conduct hypothesis-driven research. We are actively working on a bioinformatics approach to develop predictive models of risk, injury and repair and accelerate breakthrough discoveries leading to mechanism-targeted treatments that improve outcomes and minimize the burden following childhood stroke. This unique transformational resource for scientists and researchers has the potential to result in a paradigm shift in the management, outcomes and quality of life in children with stroke and their families, with far-reaching benefits for other brain conditions of people across the lifespan.

Abstract
PURPOSE OF REVIEW The goal of this paper is to describe the current understanding of lipoprotein (a) (Lp(a)), clinical practice guidelines, and the potential pathophysiological mechanisms that appear to increase the risk of cardiovascular and thromboembolic events, specifically within the pediatric population. RECENT FINDINGS The proatherogenic and pro-thrombotic properties of Lp(a) may increase the risk of atherothrombotic disease. In adults, atherosclerotic plaques increase thrombotic risk, but antifibrinolytic and proinflammatory properties appear to have an important role in children. Although it is not well established in neonates, recent studies indicate the risk of incident thrombosis and ischemic stroke are approximately fourfold higher in children with elevated Lp(a) which also increases their risk of recurrent events. Despite this higher risk, Pediatric Lp(a) screening guidelines continue to vary among different medical societies and countries. The inconsistency is likely related to inconclusive evidence outside of observational studies and the lack of specific therapies for children with elevated levels. Additional research is needed to improve understanding of the pro-thrombotic mechanisms of Lp(a), appropriate screening guidelines for Lp(a) in the pediatric population, and to elucidate the short and long term effects of elevated Lp(a) on the risk of pediatric thrombosis and stroke.

Abstract
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.

Abstract
Introduction Thrombotic events in neonates and children represent a rare although severe occurrence in view of the associated risk of mortality and sequelae. Quality evidence is limited in this field, and registry studies provide an essential base for research. The aim of this paper is to present the new Italian Registry of Infantile Thrombosis (RITI), set it into the scene of international thrombosis and stroke registries, and provide some insight on the challenges associated with registry management. Methods We present the detailed structure and content of the new RITI registry, a brief overview of its main data, and a reflection on its features, pitfalls and the main challenges related to its management. Results The RITI, initially started in 2007 and officially re-launched in 2017 after structural modifications, is a non-interventional retrospective and prospective registry study collecting data on neonatal and pediatric patients (0-18 years) who experienced a systemic or cerebral thrombotic event in Italy. The RITI is managed by a multidisciplinary team with expertise in pediatric thrombosis, and participation is open to all Italian physicians, on a voluntary basis. The overall aim of the registry is to acquire new evidence to better characterize the population of children with thrombotic events and improve their management and outcome. 48 Italian pediatric and intensive care units are actively involved in the RITI, including 85 medical doctors from 16 Italian regions. A total of 1,001 neonates and children affected by cerebral or systemic thrombosis have been enrolled. Discussion The RITI is one of the largest available European registries of neonatal and pediatric thrombosis. National registries like the RITI represent a model for the study of rare conditions based on multidisciplinary and multicenter collaboration, aimed at overcoming the limitations due to small populations of patients, and creating a network of experts for patient referral and continuous education. Moreover, registry studies have a pivotal role in the research on pediatric thrombosis, due to the limited feasibility of high-quality studies. In our experience, the main critical stages, pitfalls and challenges in registry management include adequate registry designing, diffusion, data completeness and quality control.

Abstract
Neurological morbidity is common after pediatric stroke, with moderate to severe deficits that can significantly impact education and social function. Care and recovery occur in phases distinguished by the time interval after stroke onset. These phases include the hyperacute and acute periods in which the focus is on cerebral reperfusion and prevention of neurological deterioration, followed by the subacute and chronic phases in which the focus is on secondary stroke prevention and mitigation of disability through rehabilitation, adaptation, and reintegration into the community. In this article, a multidisciplinary group of pediatric stroke experts review the stages of recovery after pediatric stroke with an emphasis on critical assessment time points. Our goal is to encourage increased standardization of outcome assessment to facilitate future clinical trials comparing various treatment and intervention options and advance optimized care for children with stroke.

Abstract
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.

Abstract
Though rare, stroke in infants and children is an important cause of mortality and chronic morbidity in the pediatric population. Neuroimaging advances and implementation of pediatric stroke care protocols have led to the ability to rapidly diagnose stroke and in many cases determine the stroke etiology. Though data on efficacy of hyperacute therapies, such as intravenous thrombolysis and mechanical thrombectomy, in pediatric stroke are limited, feasibility and safety data are mounting and support careful consideration of these treatments for childhood stroke. Recent therapeutic advances allow for targeted stroke prevention efforts in high-risk conditions, such as moyamoya, sickle cell disease, cardiac disease, and genetic disorders. Despite these exciting advances, important knowledge gaps persist, including optimal dosing and type of thrombolytic agents, inclusion criteria for mechanical thrombectomy, the role of immunomodulatory therapies for focal cerebral arteriopathy, optimal long-term antithrombotic strategies, the role of patent foramen ovale closure in pediatric stroke, and optimal rehabilitation strategies after stroke of the developing brain.

Abstract
Several studies have shown an association between varicella-zoster virus infection and ischemic stroke. We analyzed the trends in the numbers of patients with varicella, herpes zoster and ischemic stroke before and after the universal vaccination program using a Japanese database of hospitalized patients. The number of patients with varicella decreased but those of herpes zoster and ischemic stroke did not change.

Abstract
Objective: This 2-year observational study aimed to test the feasibility of implementing a pediatric stroke triage-setup that connected frontline providers with vascular neurologists and to examine final diagnoses in children triaged for suspected stroke. Methods: Prospective, consecutive registration of children with suspected stroke triaged by a team of vascular neurologists from Jan 1st, 2020 and through Dec 2021, Eastern Denmark (census 530,000 children). Based on the provided clinical information, the children were triaged to either assessment at the Comprehensive Stroke Center (CSC) in Copenhagen or to a pediatric department. All included children were retrospectively followed-up for clinical presentations and final diagnosis. Results: A total of 163 children with 166 suspected stroke events were triaged by the vascular neurologists. Cerebrovascular disease was present in 15 (9.0%) suspected stroke events; one child had intracerebral hemorrhage, one had subarachnoid hemorrhage, two children presented with three TIA events and nine children presented with 10 ischemic stroke events. Two children with ischemic stroke were eligible for acute revascularization treatment of which both were triaged to the CSC. The sensitivity of the triage by acute revascularization indication was 1.00 (95% confidence interval (95% CI): 0.15–1.00) and specificity 0.65 (95% CI: 0.57–0.73). Non-stroke neurological emergencies were present in 34 (20.5%) children, including seizures in 18 (10.8%) and acute demyelinating disorders in 7 (4.2%). Conclusion: Implementing regional triage-setup that connected frontline providers to vascular neurologists was feasible; this system was activated for the majority of children with ischemic stroke according to an expected incidence and led to identification of children eligible for revascularization treatments.

Abstract
The diagnosis of ischemic stroke in toddlers in ED is a challenge due to non-specific neurological symptoms and difficulties in conducting a detailed neurological examination in toddlers. Magnetic Resonance Imaging (MRI) requires patient sedation and the cooperation of several medical personnel. A 33-month-old male presented with the immobility of the left upper extremity after a fall from a child chair. A head computerized tomography scan revealed no obvious bleeding. An orthopedic surgeon, a neurosurgeon, and a pediatrician were consulted but could not provide a definitive diagnosis. The following day, the patient developed left incomplete hemiplegia and dysarthria, and an emergency MRI detected a high signal at the right nucleus basalis. The patient was diagnosed with acute cerebral infarction and transferred to a children's hospital. Pediatric minor head injuries and pulled elbows are commonly presented in ED, and most patients are discharged safely. Despite persistent neurological deficits several hours after arrival, we could not perform an MRI, which delayed the diagnosis. We recommend that early MRIs are performed in similar cases to aid rapid diagnoses. The collaboration between several specializations allowed the successful diagnosis and treatment of this case.

Abstract
BACKGROUND Cerebrovascular disorders are an important cause of morbidity and mortality in children. The acute care of a child with an ischemic or hemorrhagic stroke or cerebral sinus venous thrombosis focuses on stabilizing the patient, determining the cause of the insult, and preventing secondary injury. Here, we review the use of both invasive and noninvasive neuromonitoring modalities in the care of pediatric patients with arterial ischemic stroke, nontraumatic intracranial hemorrhage, and cerebral sinus venous thrombosis. METHODS Narrative review of the literature on neuromonitoring in children with cerebrovascular disorders. RESULTS Neuroimaging, near-infrared spectroscopy, transcranial Doppler ultrasonography, continuous and quantitative electroencephalography, invasive intracranial pressure monitoring, and multimodal neuromonitoring may augment the acute care of children with cerebrovascular disorders. Neuromonitoring can play an essential role in the early identification of evolving injury in the aftermath of arterial ischemic stroke, intracranial hemorrhage, or sinus venous thrombosis, including recurrent infarction or infarct expansion, new or recurrent hemorrhage, vasospasm and delayed cerebral ischemia, status epilepticus, and intracranial hypertension, among others, and this, is turn, can facilitate real-time adjustments to treatment plans. CONCLUSIONS Our understanding of pediatric cerebrovascular disorders has increased dramatically over the past several years, in part due to advances in the neuromonitoring modalities that allow us to better understand these conditions. We are now poised, as a field, to take advantage of advances in neuromonitoring capabilities to determine how best to manage and treat acute cerebrovascular disorders in children.

Abstract
AIM The aetiology of perinatal stroke is poorly understood. This study aimed to prospectively confirm the risk factors and identify any previously unknown variables. METHODS A prospective case-control study was conducted in Australia. Univariate odds ratios (ORs), associated 95% confidence intervals (CIs) and multivariable logistic regression models fitted with backwards stepwise variable selection were used. RESULTS Sixty perinatal stroke cases reported between 2017 and 2019 included 95% (57/60) with multiple risk factors. Univariate analysis identified emergency caesarean section rather than NVD (P < 0.01), low Apgar score (<7) at 1, 5 and 10 min of age (P < 0.01), resuscitation at birth (P < 0.01), abnormal cord blood gas (P < 0.01), neonatal infection/sepsis (P < 0.01), congenital heart disease (P < 0.01) and hypoglycaemia (P < 0.01) as significant risk factors. Multivariate analysis found smoking during pregnancy (OR: 1.48; 95% CI: 1.09-1.99), 1-min Apgar score < 7 (OR: 1.54; 95% CI: 1.15-2.08), 10-min Apgar score < 7 (OR: 1.26; 95% CI: 1.02-1.54) and hypoglycaemia (OR: 1.49; 95% CI: 1.07-2.06). CONCLUSIONS Perinatal stroke is associated with multiple risk factors. Exposure to smoking, 10-min Apgar score < 7, neonatal infection and hypoglycaemia were independent risk factors. Emergency caesarean section, resuscitation at birth and abnormal cord blood gas were additional risk factors.

Abstract
AbstractDifferent scales are used as outcome predictors following arterial ischemic stroke (AIS) in children. Pediatric stroke outcome measure (PSOM) gives information about neurological deficits and function and modified Rankin scale (mRS) about functional outcome. Research examining the relationship between the two measures is scarce. The aim of this study is to correlate the two different scales and to get some information on the long course of outcomes according to these outcome measures. Sixty-one children with the diagnosis of AIS and normal neurodevelopment prior to stroke were investigated. Results of outcome measures (PSOM and mRS) from ≥ 2 years of follow-up were analyzed. Changes of neurological deficits (subcategories of PSOM) over time (discharge, 6 months, and ≥2 years) and prognostic impact on the outcome of the Pediatric National Institutes of Health Stroke Scale and etiology/risk factors are presented.Cramer's V with a coefficient of 0.836 (df-1) indicates a strong association between dichotomized total PSOM and mRS scores. The correlation between the total scales was strong (rho = 0.983, p < 0.001). The correlation coefficient was highest for sensorimotor (rho = 0.949, p < 0.001), then for language (rho = 0.464, p < 0.001) and cognitive (rho = 0.363, p = 0.004) subscales. PSOM scores improved at 6 months compared to the discharge state in sensorimotor (p<0.001) and language (p<0.026) domains, however, there was no statistically significant difference between PSOM scores at 6 months and >2 years follow-up. There was no improvement in cognitive PSOM scores during the follow-up period.There was a high concordance level between the two scales, illustrating that long-term neurological deficits after stroke are related to poor functional outcome. Significant improvement of sensorimotor and language function happened within the period from onset to 6 months of follow-up. Thus, early mobilization of appropriate rehabilitative therapy might improve the outcome. We conclude that both outcome classifications are applicable for assessing outcome after childhood AIS.

Abstract
Post-stroke mood disorders (PSMD) affect disease prognosis in adults. Adult rodent models underlie the importance of the dopamine (DA) system in PSMD pathophysiology. There are no studies on PSMD after neonatal stroke. We induced neonatal stroke in 7-day-old (P7) rats by temporal left middle cerebral artery occlusion (MCAO). Performance in the tail suspension test (TST) at P14 and the forced swimming test (FST) and open field test (OFT) at P37 were studied to assess PSMD. DA neuron density in the ventral tegmental area, brain DA concentration and DA transporter (DAT) expression as well as D2 receptor (D2R) expression and G-protein functional coupling were also studied. MCAO animals revealed depressive-like symptoms at P14 associated with decreased DA concentration and reduced DA neuron population and DAT expression. At P37, MCAO rats showed hyperactive behavior associated with increased DA concentration, normalization of DA neuron density and decreased DAT expression. MCAO did not modify D2R expression but reduced D2R functionality at P37. MCAO-induced depressive-like symptoms were reversed by the DA reuptake inhibitor GBR-12909. In conclusion, MCAO in newborn rats induced depressive-like symptoms and hyperactive behavior in the medium and long term, respectively, that were associated with alterations in the DA system.

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
AbstractAlthough the association between basal ganglia (BG) stroke and mild traumatic brain injury (TBI) is well recognized, its association with lenticulostriate vasculopathy has only recently been described. We present the case of a 6-month-old female infant without personal or familiar relevant records who presented with left-sided hemiparesis and without altered consciousness after a mild TBI. An emergency computed tomography (CT) scan of the brain revealed bilateral linear calcifications along the course of the lenticulostriate arteries. Brain magnetic resonance imaging (MRI) revealed an ischemic lesion in the right BG and damage to the posterior limb of the right internal capsule. A few months after the ischemic event, the patient was asymptomatic. Given the clinical, radiological, and evolutionary characteristics of this group of patients, the term mineralizing angiopathy is proposed to define a specific clinical-imaging syndrome in infants who suffer a BG stroke after a mild TBI and present with the calcification of the lenticulostriate arteries.

Abstract
OBJECTIVE To analyze the work of the Center for the Treatment of Cerebrovascular Pathology in Children and Adolescents, operating on the basis of the Morozov Children's City Clinical Hospital of the Moscow Health Department for the period 2018-2021 and to assess the peculiarities of organizing the provision of specialized care to children and adolescents with acute cerebrovascular accident (ACA). MATERIAL AND METHODS Annual reports of the Center for the period 2018-2021; included children and adolescents aged 1 month to 17 years 11 months 29 days, with new onset ischemic stroke (IS) and hemorrhagic stroke (HS), cerebral venous thrombosis (sinus thrombosis), confirmed clinically and radiologically. RESULTS Statistical data on stroke and organization of care for children with this pathology in Moscow are presented. The incidence of IS in Moscow for the period 2018-2021 ranged from 1.6 to 2.5 per 100.000 children, HI - from 2.35 to 3.3 per 100.000, sinus thrombosis from 0.5 to 1.38 per 100.000. When assessing the main etiological factors of stroke in The Center for International Pediatric Stroke Research categories, we noted a prevalence of chronic head and neck diseases (20-37%) and chronic systemic conditions (conditions or diseases with known changes in coagulation or vascular structure, including connective tissue dysplasia, genetic, hematological, inflammatory or diseases of the immune system) (15-20%). In addition, data on reperfusion therapy carried out at the Center are presented. From 2018 (first thrombolysis was performed) to 2021, 7.3-14.7% of all patients with IS underwent thrombolysis. CONCLUSION The experience of functioning of the Center for the Treatment of Cerebrovascular Pathology in Children and Adolescents has shown that the creation of such centers in the regions of the Russian Federation is relevant, but requires taking into account the characteristics of the pediatric population when organizing their work.

Abstract
Objectives The study objective was to calculate the birth prevalence of perinatal stroke and examine risk factors in term infants. Some risk factors are present in healthy infants, making it difficult to determine at-risk infants. Study Design Prospective population-based perinatal stroke data were compared to the Australian general population data using chi-squared and Fisher's exact tests and multivariable logistic regression analysis. Results Sixty perinatal stroke cases were reported between 2017 and 2019. Estimated stroke prevalence was 9.6/100,000 live births/year including 5.8 for neonatal arterial ischemic stroke and 2.9 for neonatal hemorrhagic stroke. Eighty seven percent had multiple risk factors. Significant risk factors were cesarean section (p = 0.04), 5-min Apgar score <7 (p < 0.01), neonatal resuscitation (p < 0.01) and nulliparity (p < 0.01). Conclusions Statistically significant independent risk factors do not fully explain the cause of perinatal stroke, because they are not a direct causal pathway to stroke. These data now require validation in a case-control study.

Abstract
Aim: The rehabilitation of children who experience stroke is hampered by the lack of proven treatments and the choice of drugs and dosages. We compared clinical and neurological parameters in children receiving citicoline. Materials & methods: We assessed 199 children (128 boys, 64.3%) with stroke using the Pediatric Stroke Outcome Measure–Short Neurological Exam. Results: Hemorrhagic infarction was diagnosed more often than ischemic stroke, most often owing to the child’s early age (before and after 3 months). The presence of disorders of consciousness in the most acute and acute periods is noteworthy. Conclusion: The Pediatric Stroke Outcome Measure–Short Neurological Exam scale can be used to predict adverse outcomes. Citicoline can be administered early and is especially effective during the first year of life.

Abstract
AbstractCerebral sinovenous thrombosis (CSVT) is an uncommon condition in neonates and often leads to adverse neurodevelopmental outcomes. A high index of suspicion for CSVT is mandated for asphyxiated infants, especially following therapeutic hypothermia (TH). Magnetic resonance venography can assist in the early detection of CSVT in suspected cases. Timely initiation of anticoagulation therapy prevents thrombus propagation and allows recanalization at around 6 to 12 weeks. Long-term follow-up is essential as cognitive impairment, motor dysfunctions, and epilepsy are common complications. Herein, we describe the clinical course of a term infant who developed CSVT in the first week of life following TH for perinatal asphyxia, its management strategies, and short-term follow-up till infancy.

Abstract
Pediatric stroke is an important cause of mortality and morbidity in children. There is a paucity of clinical trials pertaining to pediatric stroke management, and solidified universal guidelines are not established for children the way they are for the adult population. Diagnosis of pediatric stroke can be challenging, and it is often delayed or mischaracterized, which can result in worse outcomes. Understanding risks and appropriate therapy is paramount to improving care.

Abstract
Pediatric stroke is a condition that often results in life-long motor, cognitive, or sensory deficits for children. The purpose of this focused review is to compile the most recent literature on pediatric stroke neuromotor interventions and summarize evidence for use by rehabilitation providers and researchers. Terms including stroke, pediatric, and neuromotor were searched with appropriate MeSH terms. Information was collected regarding interventions conducted and outcome measures used for each article. Interventions and outcome measures were organized based on ICF components (Body Structure and Function, Activity, Participation, and Environmental Factors). 16 articles were included after full-text screens. From these 16 articles, a large majority of them included some form of neuromodulation as a part of intervention. Results identified a potentially problematic gap between domains addressed by interventions and measured by outcomes, with a need to include more expansive outcome measures in research studies. There are several areas of potential growth in pediatric stroke literature. Research studies should be precise when describing included samples. As interventions for pediatric stroke shift toward neuromodulation and other neurologic treatments, there is a need for well-defined populations, both clinically in the community as well as in research studies. There is also a need for US guidelines for rehabilitation after pediatric stroke. Overall, the trend in the literature seems to suggest that combining some form of neuromodulatory technique with existing recommended rehabilitation technique (ex: CIMT) may promote overall recovery for children after stroke, though further research is needed.

Abstract
Background Even though stroke is rare in children, it is associated with serious or life-threatening consequences. Despite its rarity, the occurrence of stroke in children has age-related differences in risk factors, etiopathogenesis, and clinical presentations. Unlike adults, who have arteriosclerosis as the major cause of stroke, risk factors for pediatric strokes are multiple, including cardiac disorders, infection, prothrombotic disorders, moyamoya disease, moyamoya syndrome, and others. The goal of the current study was to compare the characteristics, clinical features, etiology, subtypes, and workup of pediatric and adult strokes. Methods This was a hospital-based observational study conducted on 222 participants. All patients underwent a full clinical and neurological examination, full laboratory study, cardiac evaluation, and neuroimaging; CT scan, MRI, MRA, MRV, carotid duplex, and transcranial Doppler (TCD). Ischemic stroke (IS) etiology was classified according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria, the "proposed classification for subtypes of arterial ischemic stroke in children," and the Oxfordshire Community Stroke Project (OCSP). Stroke severity was determined by the National Institutes of Health Stroke Scale (NIHSS) and PedNIHSS on admission. Results The proportion of pediatric ischemic strokes in the current study was 63.4 percent, while hemorrhagic strokes were 36.5%. The majority of the adult patients had ischemic strokes (84.1%), while hemorrhagic strokes were noted in 15.8% of the patients. According to the original TOAST classification, in the current study, the etiology of pediatric IS was other determined causes in 63.6%, undetermined etiology in 27.2%, and cardioembolic in 9.0%. For the adult group, the major stroke subtypes were large artery disease, small vessel disease, cardioembolic, other determined causes, and undetermined etiology at 49.6%, 28.6%, 6.9%, 0.6%, and 12.5%, respectively. Conclusions There is a greater etiological role for non-atherosclerotic arteriopathies, coagulopathies, and hematological disorders in pediatric stroke, while adults have more atherothrombotic causes. The co-existence of multiple risk factors in pediatric ischemic stroke is noticed. Thrombophilia evaluation is helpful in every case of childhood stroke. Children who have had a stroke should undergo vascular imaging as soon as possible. Imaging modalities include TCD and Doppler ultrasound, CT, MRI, MRA, and MRV, and cerebral angiography.

Abstract
This research analyzed the temporal trend of stroke mortality in children aged 0-14 years, from 1990 to 2019, in Brazil and its federative units. This ecological study used data from the Global Burden of Disease, a study led by the Institute for Health Metrics and Evaluation. Stroke definition considered the International Classification of Diseases according to codes G45, G46, and I60-I69. Age-standardized mortality rates and the mean annual percentage change (APC) in mortality rates were estimated. Stroke mortality trends decreased, with an APC of - 3.9% (95% CI - 4.5; - 3.3; p < 0.001). Reducing trends were found in all but two states, where they were stationary. Maranhão (- 6.5%; 95% CI - 7.6; - 5.4; p < 0.001) had the greatest reduction and Rondônia, the smallest (- 1.2%; 95% CI - 2.3; - 0.1, p = 0.027). Decrease was more important in children < 5 (- 5.8%; 95% CI - 6.3; - 5.2; p < 0.001) compared to 5-14 years old (- 2.1%; 95% CI - 2.9; - 1.3; p < 0.001); additionally, it was greater in girls (- 4.1%; 95% CI - 4.6; - 3.5; p < 0.001) than in boys (- 3.8%; 95% IC - 4.5; - 3.1; p < 0.001). Ischemic stroke had the highest APC (- 6.1%; 95% CI - 6.8; - 5.3; p < 0.001), followed by intracranial hemorrhage (- 5.3%; 95% CI - 6.1; - 4.5; p < 0.001) and subarachnoid hemorrhage (- 2.7%; 95% CI - 3.3; - 2.1; p < 0.001). Largest reductions were seen in states with more vulnerable socioeconomic contexts. The stationary trends and lowest APCs were concentrated in the northern region, which had greater impact of diseases and less favorable outcomes.

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
BACKGROUND Neonatal arterial ischemic stroke (NAIS) presents as seizures, including convulsions, subtle seizures, and apnea, and most patients experience neurological sequelae. Diagnosis is often delayed owing to low test sensitivity. The present study aimed to identify the early clinical diagnostic factors for NAIS in neonates with seizures. METHODS The present study included 54 patients born at ≥36 weeks of gestation during the last 15 years who presented to the neonatal intensive care unit with neonatal seizures and underwent brain magnetic resonance imaging (MRI), 6 of whom were diagnosed with NAIS. Maternal background, clinical characteristics, and transcranial pulsed Doppler sonography results were retrospectively reviewed. RESULTS Of the 24 patients who presented with convulsions or subtle seizures, 3 (13%) were diagnosed with NAIS and 3 of 30 patients (10%) presented with apnea. Maternal premature ventricular contraction complications were higher in the NAIS group than in the non-NAIS group (p = 0.01). NAIS group showed lower mean middle cerebral artery (MCA) resistance index (RI) was lower the non-NAIS group (p = 0.009), while the left-right RI difference (p = 0.019), mean MCA blood velocity (MnV; p = 0.04), and left-right MnV difference (p < 0.001) in cerebral blood flow velocities (CBFVs) were higher in the NAIS group. CONCLUSIONS Our results revealed that maternal arrhythmia may be a diagnostic factor for NAIS in neonates with seizures. Early brain MRI is essential in neonates with seizures and findings of low MCA-RI, high MCA-MnV, or high left-right difference in CBFVs to distinguish between NAIS and non-NAIS.

Abstract
Brain ischemia affects all ages, from neonates to the elderly population, and is a leading cause of mortality and morbidity. Multiple preclinical rodent models involving different ages have been developed to investigate the effect of ischemia during different times of key brain maturation events. Traditional models of developmental brain ischemia have focused on rodents at postnatal day 7-10, though emerging models in juvenile rodents (postnatal days 17-25) indicate that there may be fundamental differences in neuronal injury and functional outcomes following focal or global cerebral ischemia at different developmental ages, as well as in adults. Here, we consider the timing of injury in terms of excitation/inhibition balance, oxidative stress, inflammatory responses, blood brain barrier integrity, and white matter injury. Finally, we review translational strategies to improve function after ischemic brain injury, including new ideas regarding neurorestoration, or neural repair strategies that restore plasticity, at delayed time points after ischemia.

Abstract
Perinatal stroke is a well-defined heterogenous group of disorders involving a focal disruption of cerebral blood flow between 20 weeks gestation and 28 days of postnatal life. The most focused lifetime risk for stroke occurs during the first week after birth. The morbidity of perinatal stroke is high, as it is the most common cause of hemiparetic cerebral palsy which results in lifelong disability that becomes more apparent throughout childhood. Perinatal strokes can be classified by the timing of diagnosis (acute or retrospective), vessel involved (arterial or venous), and underlying cause (hemorrhagic or ischemic). Perinatal stroke has primarily been reported as a disorder of term infants; however, the preterm brain possesses different vulnerabilities that predispose an infant to stroke injury both in utero and after birth. Accurate diagnosis of perinatal stroke syndromes has important implications for investigations, management, and prognosis. The classification of perinatal stroke by age at presentation (fetal, preterm neonatal, term neonatal, and infancy/childhood) is summarized in this review, and includes detailed descriptions of risk factors, diagnosis, treatment, outcomes, controversies, and resources for family support.

Abstract
Although rare in children, arterial ischemic stroke (AIS) is associated with increased mortality and neurological morbidity. The incidence of AIS after the neonatal period is approximately 1-2/100,000/year, with an estimated mortality of 3-7%. A significant proportion of children surviving AIS experience life-long neurological deficits including hemiparesis, epilepsy, and cognitive delays. The low incidence of childhood AIS coupled with atypical clinical-presentation and lack of awareness contribute to delay in diagnosis and consequently, the early initiation of treatment. While randomized-clinical trials have demonstrated the efficacy and safety of reperfusion therapies including thrombolysis and endovascular thrombectomy in appropriately-selected adult patients, similar data for children are unavailable. Consequently, clinical decisions surrounding reperfusion therapy in childhood AIS are either extrapolated from adult data or based on local experience. The etiology of childhood AIS is multifactorial, often occurring in the setting of both acquired and congenital risk-factors including thrombophilia. While multiple studies have investigated the association of thrombophilia with incident childhood AIS, its impact on stroke recurrence and therefore duration and intensity of antithrombotic therapy is less clear. Despite these limitations, a significant progress has been made over the last decade in the management of childhood AIS. This progress can be attributed to international consortiums, and in selected cohorts to federally-funded clinical trials. In this narrative review, the authors have systematically appraised the literature and summarize the hemostatic and thrombotic considerations in the diagnosis and management of childhood AIS focusing on the evidence supporting reperfusion therapies, relevance of thrombophilia testing, and duration and drug choices for secondary-prophylaxis.

Abstract
Neonatal stroke is a devastating condition that causes brain injury in babies and often leads to lifelong neurological impairment. Recent prospective population studies of neonatal stroke are lacking. Neonatal strokes are different from those in older children and adults. A better understanding of its aetiology, current management, and outcomes could reduce the burden of this rare condition. The study aims to explore the incidence and 2 year outcomes of neonatal stroke across an entire population in the UK and Republic of Ireland. This is an active national surveillance study using a purpose-built integrated case notification-data collection online platform. Over a 13 month period, with a potential 6 month extension, clinicians will notify neonatal stroke cases presenting in the first 90 days of life electronically via the online platform monthly. Clinicians will complete a primary questionnaire via the platform detailing clinical information, including neuroimaging, for analysis and classification. An outcome questionnaire will be sent at 2 years of age via the platform. Appropriate ethics and regulatory approvals have been received. The neonatal stroke study represents the first multinational population surveillance study delivered via a purpose-built integrated case notification-data collection online platform and data safe haven, overcoming the challenges of setting up the study.
