Abstract
Population studies have suggested that viral infections may be contributing to risk of ischemic stroke, although the mechanisms for this are unclear. In this review, we examine the epidemiological evidence supporting the involvement of viral diseases, including influenza, COVID-19, chronic herpesvirus infections, and hepatitis C in current trends of stroke incidence. To support these associations, we highlight the virus-host interactions that are critical in the context of stroke, including direct effects of acute and persistent viral infections on vascular function, inflammation, and thrombosis. Additionally, we evaluate the systemic changes that occur during viral infection that can predispose individuals to ischemic stroke, including alterations in blood pressure regulation, coagulation, and lipid metabolism. Our review emphasizes the need to further elucidate precise mechanisms involved in viral infections and stroke risk. Future research will inform the development of targeted interventions for stroke prevention in the context of viral diseases.

Abstract
BACKGROUND Infection may trigger pediatric arterial ischemic stroke (PAIS), notably when related to focal cerebral arteriopathy. Community- and individual-level nonpharmaceutical interventions during the COVID-19 pandemic resulted in a major decrease in pediatric viral infections. We explored the consequences on the incidence of PAIS. METHODS Using national public health databases, we identified children hospitalized between 2015 and 2022 with PAIS. Using an age proxy (29 days to 7 years) and excluding patients with cardiac and hematologic conditions, we focused on children with PAIS presumably related to focal cerebral arteriopathy or with no definite cause. Considering the delay between infection and PAIS occurrence, we compared a prepandemic reference period, a period with nonpharmaceutical interventions, and a post-nonpharmaceutical intervention period. RESULTS Interrupted time-series analyses of the monthly incidence of PAIS in this group showed a significant decrease in the nonpharmaceutical intervention period compared with the prepandemic period: -33.5% (95% CI, -55.2%, -1.3%); P=0.043. CONCLUSIONS These data support the association between infection and PAIS presumably related to focal cerebral arteriopathy.

Abstract
Background Varicella zoster virus (VZV) has been associated with focal cerebral arteriopathy (FCA) and arterial ischemic stroke (AIS) in childhood. The Vascular effects of Infection in Pediatric Stroke (VIPS) II study aimed to examine this relationship in the modern era when most children in North America and Australia receive VZV vaccination with live, attenuated virus. Methods This 22-center prospective cohort study enrolled 205 children (28 days-18 years) with AIS (2017-2022), collected baseline [hyperacute (≤72 hours; n=194) and acute (4-6 days; n=181)] and convalescent (1-6 weeks; n=74) serum samples. Sites enrolled 95 stroke-free controls with single serum samples. A virology research laboratory measured VZV IgM and IgG titers by an in-house enzyme-linked immunosorbent assay (ELISA). Baseline IgG seropositivity indicated prior exposure (vaccination/infection) and elevated IgM titers indicated recent reactivation. Results Median (IQR) age was 11.6 (5.5-15.6) years for cases and 11.8 (6.8-15.3) years for controls. Baseline serologies indicated prior VZV exposure in 198 cases (97%) and all controls. Parents of cases reported VZV vaccination in 160 (78%) and remote chicken pox in three (1.4%). Twenty cases (9.8%) and three controls (3.1%) had serologic evidence of recent VZV reactivation (p=0.06); all had remote VZV exposure (vaccination in 19 cases and all controls) and all were asymptomatic. Recent VZV reactivation was seen in similar proportions in arteriopathic, cardioembolic, and idiopathic stroke. Of 32 cases of FCA, 4 (12.5%) had recent VZV reactivation, versus no cases of arterial dissection (n=10) or moyamoya (n=16). Conclusions Serologic evidence of recent VZV reactivation (≈1-6 weeks prior to stroke) was present in one in 10 cases of childhood AIS, including those without arteriopathy. Clinically silent VZV reactivation may be a childhood stroke trigger despite widespread vaccination. These cases could represent waning immunity with reactivation of either vaccine virus or wild-type virus after an unrecognized secondary VZV infection.

Abstract
BACKGROUND Time from stroke onset to hospital arrival determines treatment and impacts outcome. Structural, socioeconomic, and environmental factors are associated with health inequity and onset-to-arrival in adult stroke. We aimed to assess the association between health inequity and onset-to-arrival in a pediatric comprehensive stroke center. METHODS A retrospective observational study was conducted on a consecutive cohort of children (>28 days-18 years) diagnosed with acute arterial ischemic stroke (AIS) between 2004 and 2019. Neighborhood-level material deprivation was derived from residential postal codes and used as a proxy measure for health inequity. Patients were stratified by level of neighborhood-level material deprivation, and onset-to-arrival was categorized into 3 groups: <6, 6 to 24, and >24 hours. Association between neighborhood-level material deprivation and onset-to-arrival was assessed in multivariable ordinal logistic regression analyses adjusting for sociodemographic and clinical factors. RESULTS Two hundred and twenty-nine children were included (61% male; median age [interquartile range] at stroke diagnosis 5.8-years [1.1-11.3]). Over the 16-year study period, there was an increase in proportion of children diagnosed with AIS living in the most deprived neighborhoods and arriving at the emergency room within 6 hours (P=0.01). Among Asian patients, a higher proportion lived in the most deprived neighborhoods (P=0.02) and level of material deprivation was associated with AIS risk factors (P=0.001). CONCLUSIONS Our study suggests an increase in pediatric stroke in deprived neighborhoods and certain communities, and earlier arrival times to the emergency room over time. However, whether these changes are due to an increase in incidence of childhood AIS or increased awareness and diagnosis is yet to be determined. The association between AIS risk factors and material deprivation highlights the intersectionality of clinical factors and social determinants of health. Finally, whether material deprivation impacts onset-to-arrival is likely complex and requires further examination.

Abstract
The relationship between infections and stroke has not been fully characterized, probably delaying the development of specific treatments. This narrative review addresses mechanisms of stroke linked to infections, including hypercoagulability, endothelial dysfunction, vasculitis, and impaired thrombolysis. SARS-CoV-2, the virus that causes COVID-19, may promote the development of stroke, which may represent its most severe neurological complication. The development of specific therapies for infection-associated stroke remains a profound challenge. Perhaps the most important remaining issue is the distinction between infections that trigger a stroke versus infections that are truly incidental. This distinction likely requires the establishment of appropriate biomarkers, candidates of which are elevated levels of fibrin D-dimer and anticardiolipin/antiphospholipid antibodies. These candidate biomarkers might have potential use in identifying pathogenic infections preceding stroke, which is a precursor to establishing specific therapies for this syndrome.

Abstract
Emerging clinical and preclinical data have demonstrated that the pathophysiology of arterial ischemic stroke in the adult, neonates, and children share similar mechanisms that regulate brain damage but also have distinct molecular signatures and involved cellular pathways due to the maturational stage of the central nervous system and the immune system at the time of the insult. In this review, we discuss similarities and differences identified thus far in rodent models of 2 different diseases-neonatal (perinatal) and childhood arterial ischemic stroke. In particular, we review acquired knowledge of the role of resident and peripheral immune populations in modulating outcomes in models of perinatal and childhood arterial ischemic stroke and the most recent and relevant findings in relation to the immune-neurovascular crosstalk, and how the influence of inflammatory mediators is dependent on specific brain maturation stages. Finally, we discuss the current state of treatments geared toward age-appropriate therapies that signal via the immune-neurovascular interaction and consider sex differences to achieve successful translation.

Abstract
INTRODUCTION Major and minor pediatric infections may cause intracranial arteriopathies, the long-term outcome of which we investigated and identified the factors influencing the progression/resolution of arteriopathies. METHODS We collected the clinical and radiological data of children aged 1 month-15 years who had ischemic stroke with definite arteriopathy following a recent febrile infection. Repeated neuroimaging was done over the next year to ascertain recurrent strokes and the progression and resolution of arteriopathies. RESULTS The anterior circulation was more frequently affected (83.33%), predominantly involving the middle cerebral artery (41.67%), resolving in 20.84% of cases and progressing in 33.33% of cases. Lesions were commonly unilateral (54.17%) and stenotic (75%), resulting predominantly in cortical infarcts (45.83%), with hemiparesis being the most common neurodeficiency. Apart from tubercular meningitis patients, others had a good functional outcome. CONCLUSION Lower age, minor infections, and unilateral arteriopathies had a significantly higher chance of resolution. Postviral arteriopathies had a significantly lower chance of progression compared with those following bacterial infections. Progressive and bilateral arteriopathies were significantly associated with worse outcomes and recurrent strokes.

Abstract
PURPOSE OF REVIEW The purpose of this review is to review recent findings regarding stroke epidemiology, etiologies, and treatment in children and young adults. RECENT FINDINGS Incidence in young adults is increasing, and incidence, recurrence, and survival is worse in patients with cryptogenic stroke and in developing countries. Careful consideration of patent foramen ovale closure is now recommended in young adults with cryptogenic stroke. Thrombectomy has recently been extended to carefully selected children with acute ischemic stroke, and two recent publications strongly suggest that it can be beneficial for children. Sickle cell is also an important global contributor to stroke burden, but hydroxyurea can be a cost effective medication for stroke prevention in children. Recent advances in genetic testing and treatments may improve outcomes for patients with monogenic causes of stroke, such as deficiency of adenosine deaminase 2, hemophilia, and Fabry's disease. SUMMARY Stroke in children and young adults is a morbid disease responsible for enormous indirect societal costs and a high burden of years with disability per affected patient. Recent advances have improved access to care for children with large vessel occlusion and adults with rare causes of stroke. Future research may bring effective treatments for other monogenic causes of stroke as well as increasing access to hyperacute therapies for young stroke patients.

Abstract
Over the past few decades, robust clinical and research collaborations among pediatric stroke researchers have informed and improved the care of children with stroke. Risk factors and presentation of childhood stroke have been described, and the acute and chronic burden of childhood stroke has been better delineated. Nevertheless, high-quality data for the treatment of children with stroke is dwarfed by that available for adult stroke, and it is therefore tempting to extend research questions and treatment trials from adults to children. A trial designed to answer a question about stroke in adults may yield useful information about stroke in childhood, but a trial that incorporates the unique neurodevelopmental and etiologic aspects of childhood stroke is more likely to truly advance care. Research questions and study design in childhood stroke must capture the complexity of stroke mechanisms and medical comorbidities in children who suffer stroke, the impact on the developing nervous system, and the role of normal and aberrant neurodevelopment in recovery.

Abstract
The cerebral arteries are innervated by afferent fibers from the trigeminal ganglia. Varicella-zoster virus (VZV) frequently resides in the trigeminal ganglion. Reports of arterial ischemic stroke due to VZV cerebral vasculopathy in adults after herpes zoster have been described for decades. Reports of arterial ischemic stroke due to post-varicella cerebral arteriopathy in children have also been described for decades. One rationale for this review has been post-licensure studies that have shown an apparent protective effect from stroke in both adults who have received live zoster vaccine and children who have received live varicella vaccine. In this review, we define common features between stroke following varicella in children and stroke following herpes zoster in adults. The trigeminal ganglion and to a lesser extent the superior cervical ganglion are central to the stroke pathogenesis pathway because afferent fibers from these two ganglia provide the circuitry by which the virus can travel to the anterior and posterior circulations of the brain. Based on studies in pseudorabies virus (PRV) models, it is likely that VZV is carried to the cerebral arteries on a kinesin motor via gE, gI and the homolog of PRV US9. The gE product is an essential VZV protein.

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
Childhood stroke is not as common as adult stroke, but it is underrecognized the world over. Diagnosis is often delayed due to lack of awareness not only by the lay public but also by emergency and front-line health care workers. Despite the relative rarity of childhood stroke, the impact on morbidity, mortality and the economic burden for families and society is high, especially in poorly resourced settings. The risk factors for stroke in children differ from the adult population where lifestyle factors play a more important role. The developmental aspects of the pediatric cerebral vasculature and hematological maturational biology affects the clinical presentation, investigation, management and outcomes of childhood stroke in a different way compared to adults. The management of childhood stroke is currently based on expert guidelines and evidence extrapolated from adult studies. Hyperacute therapies that have revolutionized the treatment of stroke in adults cannot be easily applied to children at this stage due to the diagnostic delays, diverse risk factors and developmental considerations mentioned above. Much has been achieved in the understanding of genetic, acquired, preventable and recurrent stroke risk factors in the past decade through international collaborative efforts like the International Pediatric Stroke Study. Evidence for the prevention and treatment of childhood stroke remains elusive. Even more elusive are relevant and achievable management guidelines for pediatric stroke in resource-limited settings. This narrative review focusses on the current management practices globally, emphasizing the challenges, and gaps in knowledge of pediatric stroke in low- and middle-income countries and other areas with limited resources. Priorities and some potential solutions at national and local level are suggested for these settings.

Abstract
Global awareness of stroke as a significant cause of neurologic sequelae and death in children has increased over the years as more data in this field becomes available. However, most published literature on pediatric stroke have limited geographic representation. Data on childhood stroke from developing countries remains limited. Thus, this paper reviewed geographic/ethnic differences in pediatric stroke risk factors highlighting those reported in low- and middle-income countries, and proposes a childhood arterial ischemic stroke diagnostic algorithm for resource limited settings. Stroke risk factors include cardiac disorders, infectious diseases, cerebral arteriopathies, hematologic disorders, inflammatory diseases, thrombophilia and genetic conditions. Infection of the central nervous system particularly tuberculous meningitis, is a leading cause of pediatric arterial ischemic stroke in developing countries. Stroke should be considered in children with acute focal neurologic deficit especially in the presence of aforementioned risk factors. Cranial magnetic resonance imaging with angiography is the neuroimaging modality of choice but if unavailable, cranial computed tomography with angiography may be performed as an alternative. If both are not available, transcranial doppler together with neurologic exam may be used to screen children for arterial ischemic stroke. Etiological diagnosis follows with the aid of appropriate laboratory tests that are available in each level of care. International collaborative research on stroke risk factors that are prevalent in low and middle income countries will provide information for drafting of stroke care guidelines that are universal yet inclusive taking into consideration regional differences in available resources with the goal of reducing global stroke burden.

Abstract
Infections play an important role in the pathogenesis of acute ischemic stroke (AIS) in neonates and children. In neonates, chorioamnionitis or intrauterine inflammation has been implicated as a common risk factor for AIS. In infants and children, recent investigations demonstrated that even minor childhood infections are associated with subsequent increased risk for AIS. Post-infectious inflammatory mechanisms following infections with herpesviruses may lead to focal cerebral arteriopathy (FCA), one of the most common causes of AIS in a previously healthy child. Other agents such as parvovirus B19, dengue virus, and SARS-CoV-2 have recently been implicated as other potential triggers. Infections are compelling treatable stroke risk factors, with available therapies for both pathogens and downstream inflammatory effects. However, infections are common in childhood, while stroke is uncommon. The ongoing VIPS II (Vascular effects of Infection in Pediatric Stroke) study aims to identify the array of pathogens that may lead to childhood AIS and whether either unusual strains or unusual combinations of pathogens explain this paradox. Immune modulation with corticosteroids for FCA is another active area of research, with European and U.S. trials launching soon. The results of these new pediatric stroke studies combined with findings emerging from the larger field of immune-mediated post-infectious diseases will likely lead to new approaches to the prevention and treatment of pediatric stroke. This review highlights recent developments from both clinical and animal model research enhancing our understanding of this relationship between infection, inflammation, and stroke in neonates and children.

Abstract
BACKGROUND There is an increased risk of stroke in adults with severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) infection, but whether there is a similar association with stroke in children is unclear. Our objective was to determine whether there is a correlation between COVID-19 infection, multisystem inflammatory syndrome in children (MIS-C), and pediatric ischemic stroke. METHODS This was a retrospective, population-based cohort analysis between March 1, 2020, and June 30, 2021, conducted at a children's hospital. Pediatric patients with a diagnosis of ischemic stroke were identified using ICD-10 diagnoses of ischemic stroke, cerebrovascular accident, or cerebral infarction. RESULTS We identified 16 patients, seven male and nine female, with ischemic stroke. Ages were 8 months to 17 years (median 11.5 years). More Asian (6%) and black (13%) patients had strokes compared with population prevalence (2% each, respectively). No patients had active COVID-19 infection. COVID-19 antibodies were identified in five of 11 patients tested (45%), of whom three were diagnosed with MIS-C. 82% of the strokes occurred between February and May 2021. The peak incidence was in February 2021, which was two months after peak incidence of pediatric cases of COVID-19 and one month after the peak of MIS-C cases. CONCLUSIONS Our study suggests that prior COVID-19 infection, but not acute infection, is correlated with a risk for stroke in the pediatric population. The risk for stroke appears to be distinct from the risk for MIS-C.

Abstract
Choroid plexus epithelial cells can secrete cerebrospinal fluid into the ventricles, serving as the major structural basis of the selective barrier between the neurological system and blood in the brain. In fact, choroid plexus epithelial cells release the majority of cerebrospinal fluid, which is connected with particular ion channels in choroid plexus epithelial cells. Choroid plexus epithelial cells also produce and secrete a number of essential growth factors and peptides that help the injured cerebrovascular system heal. The pathophysiology of major neurodegenerative disorders like Alzheimer's disease, Parkinson's disease, as well as minor brain damage diseases like hydrocephalus and stroke is still unknown. Few studies have previously connected choroid plexus epithelial cells to the etiology of these serious brain disorders. Therefore, in the hopes of discovering novel treatment options for linked conditions, this review extensively analyzes the association between choroid plexus epithelial cells and the etiology of neurological diseases such as Alzheimer's disease and hydrocephalus. Finally, we review CPE based immunotherapy, choroid plexus cauterization, choroid plexus transplantation, and gene therapy.

Abstract
Up to more than half of previously healthy children presenting with their first arterial ischemic stroke have a cerebral arteriopathy. Cerebral arteriopathies during childhood can be congenital, reflecting abnormal vessel development, or acquired when caused by disruption of vascular homeostasis. Distinguishing different types of cerebral arteriopathies in children can be challenging but of great clinical value as they may dictate different disease and treatment courses, and clinical and radiologic outcomes. Furthermore, children with stroke due to a specific arteriopathy exhibit distinctive features when compared to those with stroke due to other causes or a different type of arteriopathy. These features become crucial in the management of pediatric stroke by choosing appropriate diagnostic and treatment strategies. The objective of this article is to provide the reader with a comprehensive up-to-date review of the classification, symptoms, diagnosis, treatment, and outcome of cerebral arteriopathies in children.

Abstract
Introduction The present study aimed to evaluate the prevalence of arterial ischaemic stroke (AIS) in Polish children, as well as to analyse the parameters related to AIS hospitalisation, including age, gender, region, month and season of the year at admission, duration, and costs, based on data from National Health Fund (NHF) registry in 2011-2020. Material and methods Data from the NHF were analysed statistically. The disease was identified according to the codes I63 and I64 of the International Classification of Diseases, 10th Revision (ICD-10), and patients included only individuals up to 18 years of age. Results We identified 622 hospitalisations due to paediatric AIS in Poland in the study period. The most frequent age subgroups were adolescents, followed by toddlers or pre-school children (34.73% and 24.12%, respectively), while the least frequent were neonates or infants (9.81%). ICD-10 procedures did significantly affect the duration and costs of hospitalisation (p < 0.001). The highest costs of hospitalisations concerned the I63.1 procedure (cerebral infarction due to embolism of precerebral arteries), which included thrombectomy. The duration and costs of hospitalisation were positively correlated with each other (r = 0.525, p < 0.001). Age correlated negatively with duration of hospitalisation (r = -0.154, p < 0.001) and positively with costs of hospitalisation (r = 0.133, p = 0.008). Conclusions Data from the NHF registry proved that AIS occurs more often in boys than in girls and is more common in adolescents (15-18 years) than in younger children.

Abstract
Der arteriell ischämische Schlaganfall im Kindes- und Jugendalter gehört zu den zeitkritischsten pädiatrischen Notfällen, wird aber häufig erst mit prognostisch relevanter Zeitverzögerung diagnostiziert. Gründe sind geringe „Awareness“, die zuweilen unspezifische klinische Präsentation mit einer Breite an kritischen Differenzialdiagnosen und in der Fläche noch wenig verzahnte Akutversorgungsstrukturen. Die beim Erwachsenen etablierten Revaskularisationsstrategien zeigen auch beim Kind mögliche, z. T. spektakuläre Erfolge. Diese sind daher nach Möglichkeit auch betroffenen Kindern zur Verfügung zu stellen, auch wenn hier derzeit keine annähernd vergleichbare Evidenz vorliegt. Postakut ist die ätiologische Aufarbeitung aufgrund zu bedenkender Risikofaktoren komplex, muss aber das individuelle Risikoprofil mit Sekundärprophylaxe, Rezidivrisiko und Outcome präzise identifizieren. Die Langzeitbetreuung im multiprofessionellen, interdisziplinären Team muss die bio-psycho-sozialen Aspekte des Kindes in seiner jeweiligen Entwicklungsphase berücksichtigen.

Abstract
Stroke is an important cause of neurological morbidity in children; most survivors have permanent neurological deficits that affect the remainder of their life. Stroke in childhood, the focus of this Primer, is distinguished from perinatal stroke, defined as stroke before 29 days of age, because of its unique pathogenesis reflecting the maternal-fetal unit. Although approximately 15% of strokes in adults are haemorrhagic, half of incident strokes in children are haemorrhagic and half are ischaemic. The causes of childhood stroke are distinct from those in adults. Urgent brain imaging is essential to confirm the stroke diagnosis and guide decisions about hyperacute therapies. Secondary stroke prevention strongly depends on the underlying aetiology. While the past decade has seen substantial advances in paediatric stroke research, the quality of evidence for interventions, such as the rapid reperfusion therapies that have revolutionized arterial ischaemic stroke care in adults, remains low. Substantial time delays in diagnosis and treatment continue to challenge best possible care. Effective primary stroke prevention strategies in children with sickle cell disease represent a major success, yet barriers to implementation persist. The multidisciplinary members of the International Pediatric Stroke Organization are coordinating global efforts to tackle these challenges and improve the outcomes in children with cerebrovascular disease.

Abstract
This review provides an updated analysis of the main aspects involving the diagnosis and the management of children with acute ischemic stroke. Acute ischemic stroke is an emergency of rare occurrence in children (rate of incidence of 1/3500 live birth in newborns and 1-2/100,000 per year during childhood with peaks of incidence during the perinatal period, under the age of 5 and in adolescence). The management of ischemic stroke in the paediatric age is often challenging because of pleomorphic age-dependent risk factors and aetiologies, high frequency of subtle or atypical clinical presentation, and lacking evidence-based data about acute recanalization therapies. Each pediatric tertiary centre should activate adequate institutional protocols for the optimization of diagnostic work-up and treatments.Conclusion: The implementation of institutional standard operating procedures, summarizing the steps for the selection of candidate for neuroimaging among the ones presenting with acute neurological symptoms, may contribute to shorten the times for thrombolysis and/or endovascular treatments and to improve the long-term outcome. What is Known: •Acute ischemic stroke has a higher incidence in newborns than in older children (1/3500 live birth versus 1-2/100,000 per year). •Randomized clinical trial assessing safety and efficacy of thrombolysis and/or endovascular treatment were never performed in children What is New: •Recent studies evidenced a low risk (2.1% of the cases) of intracranial haemorrhages in children treated with thrombolysis. •A faster access to neuroimaging and hyper-acute therapies was associated with the implementation of institutional protocols for the emergency management of pediatric stroke.

Abstract
OBJECTIVES To define the incidence and characteristics of influenza-associated neurologic complications in a cohort of children hospitalized at a tertiary care pediatric hospital with laboratory-confirmed influenza and to identify associated clinical, epidemiologic, and virologic factors. STUDY DESIGN This was an historical cohort study of children aged 0.5-18.0 years old hospitalized between 2010 and 2017 with laboratory-confirmed influenza. Children with immune compromise or a positive test due to recent receipt of live virus vaccine or recently resolved illness were excluded. Influenza-associated neurologic complications were defined as new-onset neurologic signs/symptoms during acute influenza illness without another clear etiology. RESULTS At least 1 influenza-associated neurologic complication was identified in 10.8% (95% CI 9.1-12.6%, n = 131 of 1217) of hospitalizations with laboratory-confirmed influenza. Seizures (n = 97) and encephalopathy (n = 44) were the most commonly identified influenza-associated neurologic complications, although an additional 20 hospitalizations had other influenza-associated neurologic complications. Hospitalizations with influenza-associated neurologic complications were similar in age and influenza type (A/B) to those without. Children with a pre-existing neurologic diagnosis (n = 326) had a greater proportion of influenza-associated neurologic complications compared with those without (22.7% vs 6.4%, P < .001). Presence of a pre-existing neurologic diagnosis (aOR 4.6, P < .001), lack of seasonal influenza vaccination (aOR 1.6, P = .020), and age ≤5 years (aOR 1.6, P = .017) were independently associated with influenza-associated neurologic complications. CONCLUSIONS Influenza-associated neurologic complications are common in children hospitalized with influenza, particularly those with pre-existing neurologic diagnoses. A better understanding of the epidemiology and factors associated with influenza-associated neurologic complications will direct future investigation into potential neuropathologic mechanisms and mitigating strategies. Vaccination is recommended and may help prevent influenza-associated neurologic complications in children.

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

Abstract
BACKGROUND Neonatal arterial ischemic stroke (NAIS) carries the risk of significant long-term neurodevelopmental burden on survivors. AIMS To assess the long-term neurodevelopmental outcome of term neonates diagnosed with NAIS and investigate the associations among brain territorial involvement on MRI, clinical risk factors and neurodevelopmental outcomes. STUDY DESIGN Population-based cohort study. SUBJECTS Seventy-nine term neonates with NAIS confirmed by MRI born between 2007 and 2017. OUTCOME MEASURES Long-term neurodevelopmental outcome assessed using the Bayley Scales of Infant Development-II, the Brunet-Lézine test and the Binet Intelligence scales-V. RESULTS Follow-up was available in 70 (89%) of the subjects enrolled, at a median age of 60 months [IQR: 35-84]. Normal neurodevelopmental outcome was found in 43% of the patients. In a multivariable model, infants with main MCA stroke had an increased risk for overall adverse outcome (OR: 9.1, 95% CI: 1.7-48.0) and a particularly high risk for cerebral palsy (OR: 55.9, 95% CI: 7.8-399.2). The involvement of the corticospinal tract without extensive stroke also increased the risk for cerebral palsy/fine motor impairment (OR: 13.5, 95% CI: 2.4-76.3). Multiple strokes were associated with epilepsy (OR: 9.5, 95% CI: 1.0-88.9) and behavioral problems (OR: 4.4, 95% CI: 1.1-17.5) and inflammation/infection was associated with cerebral palsy (OR: 9.8, 95% CI: 1.4-66.9), cognitive impairment (OR: 9.2, 95% CI: 1.8-47.8) and epilepsy (OR: 10.3, 95% CI: 1.6-67.9). CONCLUSIONS Main MCA stroke, involvement of the corticospinal tract, multiple strokes and inflammation/infection were independent predictors of adverse outcome, suggesting that the interplay of stroke territorial involvement and clinical risk factors influence the outcome of NAIS.

Abstract
Neurologic manifestations associated with Covid-19 are increasingly reported, especially stroke and acute cerebrovascular events. Beyond cardiovascular risk factors associated with age, some young adults without medical or cardiovascular history had stroke as a presenting feature of Covid-19. Suggested stroke mechanisms in this setting are inflammatory storm, subsequent hypercoagulability, and vasculitis. To date, a handful of pediatric stroke cases associated with Covid-19 have been reported, either with a cardioembolic mechanism or a focal cerebral arteriopathy. We report the case of an adolescent who presented with febrile meningism and stupor. Clinical, biological, and radiological features favored the diagnosis of Lemierre syndrome (LS), with Fusobacterium necrophorum infection (sphenoid sinusitis and meningitis) and intracranial vasculitis. The patient had concurrent SARS-CoV-2 infection. Despite medical and surgical antimicrobial treatment, stroke prevention, and venous thrombosis prevention, he presented with severe cerebrovascular complications. Venous thrombosis and stroke were observed, with an extension of intracranial vasculitis, and lead to death. As both F. necrophorum and SARS-CoV-2 enhance inflammation, coagulation, and activate endothelial cells, we discuss how this coinfection may have potentiated and aggravated the usual course of LS. The potentiation by SARS-CoV-2 of vascular and thrombotic effects of a bacterial infection may represent an underreported cerebrovascular injury mechanism in Covid-19 patients. These findings emphasize the variety of mechanisms underlying stroke in this disease. Moreover, in the setting of SARS-CoV-2 pandemic, we discuss in what extent sanitary measures, namely, lockdown and fear to attend medical facilities, may have delayed diagnosis and influenced outcomes. This case also emphasizes the role of clinical assessment and the limits of telemedicine for acute neurological condition diagnosis.

Abstract
AIM To determine whether socioeconomic status (SES) is a stronger predictor for cognitive outcome after childhood arterial ischemic stroke compared to clinical factors. METHOD We investigated perceptual reasoning, executive functions, language, memory, and attention in 18 children and adolescents (12 males, six females, median age at testing 13y 4mo, range 7y-17y 5mo) after arterial ischemic stroke; collected sociodemographic information (education of parents, household income); and used clinical information (initial lesion volume, residual lesion volume, age at stroke, time since stroke). Linear regression models were used to investigate the potential influence of SES and clinical parameters on cognitive abilities. RESULTS SES had a moderate effect on all cognitive outcome parameters except attention by explaining 41.9%, 37.9%, 38.0%, and 22.5% of variability in perceptual reasoning, executive functions, language, and memory respectively. Initial lesion volume was the only clinical parameter that showed moderate importance on cognitive outcome (33.1% and 25.6% of the variability in perceptual reasoning and memory respectively). Overall, SES was a stronger predictor of cognitive outcome than clinical factors. INTERPRETATION Future paediatric studies aiming at clinical predictors of cognitive outcome should control their analyses for SES in their study participants. The findings of the present study further point to the need for more attention to the treatment of children with low SES. WHAT THIS PAPER ADDS Socioeconomic status (SES) explains up to 42% of variance in cognitive outcome after childhood arterial ischemic stroke. SES is a stronger predictor of outcome than clinical factors.

Abstract
INTRODUCTION Acute infections are known triggers of cardiovascular disease (CVD) but how this association varies across infection types is unknown. We hypothesized while acute infections increase CVD risk, the strength of this association varies across infection types. METHOD Acute coronary heart disease (CHD) and ischemic stroke cases were identified in the Atherosclerosis Risk in Communities Study (ARIC). ICD-9 codes from Medicare claims were used to identify cellulitis, pneumonia, urinary tract infections (UTI), and bloodstream infections. A case-crossover design and conditional logistic regression were used to compare infection types among acute CHD and stroke cases 14, 30, 42, and 90 days before the event with two corresponding control periods (1 and 2 years prior). RESULTS Of the 1312 acute CHD cases, 116 had a UTI, 102 had pneumonia, 43 had cellulitis, and 28 had a bloodstream infection 90 days before the CHD event. Pneumonia (OR = 25.53 (9.21,70.78)), UTI (OR = 3.32 (1.93, 5.71)), bloodstream infections (OR = 5.93 (2.07, 17.00)), and cellulitis (OR = 2.58 (1.09, 6.13)) were associated with higher acute CHD risk within 14 days of infection. Of the 727 ischemic stroke cases, 12 had cellulitis, 27 had pneumonia, 56 had a UTI, and 5 had a bloodstream infection within 90 days of the stroke. Pneumonia (OR = 5.59 (1.77, 17.67)) and UTI (OR = 3.16 (1.68, 5.94)) were associated with higher stroke risk within 14 days of infection. CONCLUSIONS Patients with pneumonia, UTI, or bloodstream infection appear to be at a 2.5 to 25.5 fold elevated CVD risk following infection. Preventive therapies during this high-risk period should be considered.

Abstract
Maternal mortality rates have been steadily increasing in the United States, and cardiovascular mortality is the leading cause of death among pregnant and postpartum women. Maternal stroke accounts for a significant burden of cardiovascular mortality. Data suggest that rates of maternal stroke have been increasing in recent years. Advancing maternal age at the time of birth and the increasing prevalence of traditional cardiovascular risk factors, and other risk factors, as well, such as hypertensive disorders of pregnancy, migraine, and infections, may contribute to increased rates of maternal stroke. In this article, we provide an overview of the epidemiology of maternal stroke, explore mechanisms that may explain increasing rates of stroke among pregnant women, and identify key knowledge gaps for future investigation in this area.

Abstract
OBJECTIVE Severe complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) include arterial ischemic stroke (AIS) in adults and multisystem inflammatory syndrome in children. Whether stroke is a frequent complication of pediatric SARS-CoV-2 is unknown. This study aimed to determine the proportion of pediatric SARS-CoV-2 cases with ischemic stroke and the proportion of incident pediatric strokes with SARS-CoV-2 in the first 3 months of the pandemic in an international cohort. METHODS We surveyed 61 international sites with pediatric stroke expertise. Survey questions included: numbers of hospitalized pediatric (≤ 18 years) patients with SARS-CoV-2; numbers of incident neonatal and childhood ischemic strokes; frequency of SARS-CoV-2 testing for pediatric patients with stroke; and numbers of stroke cases positive for SARS-CoV-2 from March 1 to May 31, 2020. RESULTS Of 42 centers with SARS-CoV-2 hospitalization numbers, 8 of 971 (0.82%) pediatric patients with SARS-CoV-2 had ischemic strokes. Proportions of stroke cases positive for SARS-CoV-2 from March to May 2020 were: 1 of 108 with neonatal AIS (0.9%), 0 of 33 with neonatal cerebral sinovenous thrombosis (CSVT; 0%), 6 of 166 with childhood AIS (3.6%), and 1 of 54 with childhood CSVT (1.9%). However, only 30.5% of neonates and 60% of children with strokes were tested for SARS-CoV-2. Therefore, these proportions represent 2.9, 0, 6.1, and 3.0% of stroke cases tested for SARS-CoV-2. Seven of 8 patients with SARS-CoV-2 had additional established stroke risk factors. INTERPRETATION As in adults, pediatric stroke is an infrequent complication of SARS-CoV-2, and SARS-CoV-2 was detected in only 4.6% of pediatric patients with ischemic stroke tested for the virus. However, < 50% of strokes were tested. To understand the role of SARS-CoV-2 in pediatric stroke better, SARS-CoV-2 testing should be considered in pediatric patients with stroke as the pandemic continues. ANN NEUROL 2021;89:657-665.

Abstract
INTRODUCTION Various neurological complications may occur as a consequence of arterial ischemic stroke (AIS) and have an impact on daily activity of the patients, costs of their medical care and rehabilitation. The aim of this study was to analyze risk factors, stroke symptoms and post-stroke consequences in Polish pediatric patients depending on stroke subtype. MATERIAL AND METHODS We retrospectively reviewed 77 children under the age of 18 years following their first AIS. Patients were white, Polish Caucasians, recruited in the Department of Pediatric Neurology at the Medical University of Silesia in Katowice (Poland). Statistical analysis was performed using Statistica 12.0. RESULTS Gender differed significantly between stroke subgroups (p = 0.030). The presence of focal cerebral arteriopathy (FCA) and chronic diseases was associated with type of AIS (p = 0.003 and p = 0.050, respectively). An outcome without neurological deterioration (normal outcome) was observed in 43% of children with lacunar anterior circulation infarct (LACI). Hemiparesis was present in almost all children with total anterior circulation infarct (TACI), in two thirds of children with partial anterior circulation infarct (PACI) and in almost 50% of children with LACI or posterior circulation infarct (POCI). In every child with hemiplegia the stroke symptom evolved into hemiparesis at follow-up. Additionally, patients with a normal outcome were older at the time of AIS than those with at least one neurological consequence (OR = 0.894, p = 0.034). CONCLUSIONS The presence and number of neurological outcomes depend on stroke subtypes. A relation between the presence of post-stroke deficits and age at onset was observed. The odds of deficit after ischemic stroke decreases by an average of 10.6% if the child is 1 year older at the time of AIS.

Abstract
BACKGROUND AND PURPOSE To assess whether initial imaging characteristics independently predict 1-year neurological outcomes in childhood arterial ischemic stroke patients. METHODS We used prospectively collected demographic and clinical data, imaging data, and 1-year outcomes from the VIPS study (Vascular Effects of Infection in Pediatric Stroke). In 288 patients with first-time stroke, we measured infarct volume and location on the acute magnetic resonance imaging studies and hemorrhagic transformation on brain imaging studies during the acute presentation. Neurological outcome was assessed with the Pediatric Stroke Outcome Measure. We used univariate and multivariable ordinal logistic regression models to test the association between imaging characteristics and outcome. RESULTS Univariate analysis demonstrated that infarcts involving uncinate fasciculus, angular gyrus, insular cortex, or that extended from cortex to the subcortical nuclei were significantly associated with poorer outcomes with odds ratios ranging from 1.95 to 3.95. All locations except the insular cortex remained significant predictors of poor outcome on multivariable analysis. When infarct volume was added to the model, the locations did not remain significant. Larger infarct volumes and younger age at stroke onset were significantly associated with poorer outcome, but the strength of the relationships was weak. Hemorrhagic transformation did not predict outcome. CONCLUSIONS In the largest pediatric arterial ischemic stroke cohort collected to date, we showed that larger infarct volume and younger age at stroke were associated with poorer outcomes. We made the novel observation that the strength of these associations was modest and limits the ability to use these characteristics to predict outcome in children. Infarcts affecting specific locations were significantly associated with poorer outcomes in univariate and multivariable analyses but lost significance when adjusted for infarct volume. Our findings suggest that infarcts that disrupt critical networks have a disproportionate impact upon outcome after childhood arterial ischemic stroke.

Abstract
Understanding the relationship between infection and stroke has taken on new urgency in the era of the coronavirus disease 2019 (COVID-19) pandemic. This association is not a new concept, as several infections have long been recognized to contribute to stroke risk. The association of infection and stroke is also bidirectional. Although infection can lead to stroke, stroke also induces immune suppression which increases risk of infection. Apart from their short-term effects, emerging evidence suggests that poststroke immune changes may also adversely affect long-term cognitive outcomes in patients with stroke, increasing the risk of poststroke neurodegeneration and dementia. Infections at the time of stroke may also increase immune dysregulation after the stroke, further exacerbating the risk of cognitive decline. This review will cover the role of acute infections, including respiratory infections such as COVID-19, as a trigger for stroke; the role of infectious burden, or the cumulative number of infections throughout life, as a contributor to long-term risk of atherosclerotic disease and stroke; immune dysregulation after stroke and its effect on the risk of stroke-associated infection; and the impact of infection at the time of a stroke on the immune reaction to brain injury and subsequent long-term cognitive and functional outcomes. Finally, we will present a model to conceptualize the many relationships among chronic and acute infections and their short- and long-term neurological consequences. This model will suggest several directions for future research.

Abstract
Background Acute infections are known cardiovascular disease (CVD) triggers, but little is known regarding how CVD risk varies following inpatient versus outpatient infections. We hypothesized that in‐ and outpatient infections are associated with CVD risk and that the association is stronger for inpatient infections. Methods and Results Coronary heart disease (CHD) and ischemic stroke cases were identified and adjudicated in the ARIC (Atherosclerosis Risk in Communities Study). Hospital discharge diagnosis codes and Medicare claims data were used to identify infections diagnosed in in‐ and outpatient settings. A case‐crossover design and conditional logistic regression were used to compare in‐ and outpatient infections among CHD and ischemic stroke cases (14, 30, 42, and 90 days before the event) with corresponding control periods 1 and 2 years previously. A total of 1312 incident CHD cases and 727 incident stroke cases were analyzed. Inpatient infections (14‐day odds ratio [OR]=12.83 [5.74, 28.68], 30‐day OR=8.39 [4.92, 14.31], 42‐day OR=6.24 [4.02, 9.67], and 90‐day OR=4.48 [3.18, 6.33]) and outpatient infections (14‐day OR=3.29 [2.50, 4.32], 30‐day OR=2.69 [2.14, 3.37], 42‐day OR=2.45 [1.97, 3.05], and 90‐day OR=1.99 [1.64, 2.42]) were more common in all CHD case periods compared with control periods and inpatient infection was a stronger CHD trigger for all time periods (P<0.05). Inpatient infection was also a stronger stroke trigger with the difference borderline statistically significant (P<0.10) for the 42‐ and 90‐day time periods. Conclusions In‐ and outpatient infections are associated with CVD risk. Patients with an inpatient infection may be at particularly elevated CVD risk and should be considered potential candidates for CVD prophylaxis.

Abstract
BACKGROUND In recent years, there has been increasing research interest in improving diagnostic and management protocols in childhood arterial ischaemic stroke (AIS). However, childhood stroke comprises, in approximately equal parts, both arterial ischaemic and haemorrhagic stroke (HS). OBJECTIVE The aim of this study was to focus on the aetiology, clinical presentation, treatment and short-term outcome of children with spontaneous intracranial bleeding in a university hospital and elucidate differences to childhood AIS. DESIGN We performed a retrospective analysis of electronic medical records of children (28 days-18 years) diagnosed with HS between 2010 and 2016. RESULTS We included 25 children (male child, n=11) with a median age of 8 years 1 month. The most common clinical presentations were vomiting (48%), headache (40%) and altered level of consciousness (32%). In more than half of the patients, HS was caused by vascular malformations. Other risk factors were brain tumour, coagulopathy and miscellaneous severe underlying diseases. Aetiology remained unclear in one child. Therapy was neurosurgical in most children (68%). Two patients died, 5 patients needed further (rehabilitation) treatment and 18 children could be discharged home. CONCLUSIONS HS differs from AIS in aetiology (vascular malformations as number one risk factor), number of risk factors ('mono-risk' disease), clinical presentation (vomiting, headache and altered level of consciousness) and (emergency) therapy.

Abstract
OBJECTIVE We describe the risk factors for peri-procedural and spontaneous arterial ischemic stroke (AIS) in children with cardiac disease. METHODS We identified children with cardiac causes of AIS enrolled in the International Pediatric Stroke Study registry from January 2003 to July 2014. Isolated patent foramen ovale was excluded. Peri-procedural AIS (those occurring during or within 72 hours of cardiac surgery, cardiac catheterization, or mechanical circulatory support) and spontaneous AIS that occurred outside of these time periods were compared. RESULTS We identified 672 patients with congenital or acquired cardiac disease as the primary risk factor for AIS. Among these, 177 patients (26%) had peri-procedural AIS and 495 patients (74%) had spontaneous AIS. Among non-neonates, spontaneous AIS occurred at older ages (median 4.2 years, interquartile range 0.97 to 12.4) compared with peri-procedural AIS (median 2.4 years, interquartile range 0.35 to 6.1, P < 0.001). About a third of patients in both groups had a systemic illness at the time of AIS. Patients who had spontaneous AIS were more likely to have a preceding thrombotic event (16 % versus 9 %, P = 0.02) and to have a moderate or severe neurological deficit at discharge (67% versus 33%, P = 0.01) compared to those with peri-procedural AIS. CONCLUSIONS Children with cardiac disease are at risk for AIS at the time of cardiac procedures but also outside of the immediate 72 hours after procedures. Many have acute systemic illness or thrombotic event preceding AIS, suggesting that inflammatory or prothrombotic conditions could act as a stroke trigger in this susceptible population.

Abstract
Background and Purpose- Most cases of pregnancy-related ischemic stroke (IS) and hemorrhagic stroke (HS) occur postpartum. Infections have been identified as a trigger for strokes in young people and have been associated with strokes during delivery hospitalizations, but a temporal relationship has been difficult to establish. We hypothesized that infections diagnosed during a delivery admission would be associated with an increased risk of readmission for postpartum stroke. Methods- We conducted a retrospective cohort study using the Healthcare Cost and Utilization Project's National Readmissions Database from 2010 to 2014. Using weighted survey design Poisson regression analysis, we calculated adjusted risk ratios (aRR) and 95% CI for the association between infection during delivery admission and 30-day postpartum readmission for IS or HS. Results- Out of 17.2 million delivery admissions during the study period, 2128 were readmitted within 30 days for a stroke of any type. There were 1189 HS (intracerebral hemorrhage or subarachnoid hemorrhage) and 720 IS, and the remainder unspecified pregnancy-related stroke. Adjusting for age and comorbidities, women with delivery infections were at higher risk of readmission for postpartum stroke of any type (aRR, 1.19; 95% CI, 1.01-1.41). Women with infections had higher risk of readmission for postpartum IS (aRR, 1.75; 95% CI, 1.37-2.22), but not for postpartum HS (aRR, 0.96; 95% CI, 0.75-1.23). The effect of infection on 30-day IS readmission was larger in women without hypertensive disorders of pregnancy (aRR, 2.0; 95% CI, 1.55-2.69 in women without hypertensive disorders of pregnancy versus aRR, 1.47; 95% CI, 0.9-2.38 in women with hypertensive disorders of pregnancy, P value for interaction=0.09). Conclusions- Infection during delivery hospitalization was associated with increased risk of readmission for IS, but not HS, within 30 days postpartum, particularly in women without hypertensive disorders of pregnancy. Infection may play a role in triggering postpartum IS even in the absence of other risk factors.

Abstract
Background and Purpose- Focal cerebral arteriopathy (FCA)-a common cause of arterial ischemic stroke in previously healthy children-often progresses over days to weeks, increasing the risk of recurrent stroke. We developed a novel severity scoring system designed to quantify FCA progression and correlate with clinical outcomes. Methods- The VIPS study (Vascular Effects of Infection in Pediatric Stroke) prospectively enrolled 355 children with arterial ischemic stroke (2010-2014), including 41 with centrally confirmed FCA. Two neuroradiologists independently reviewed FCA cerebrovascular imaging, assigning a graded severity score of zero (no involvement) to 4 (occlusion) to individual arterial segments. The FCA severity score (FCASS) was the unweighted sum. In an iterative process, we modeled scores derived from different combinations of arterial segments to identify the model that optimized correlation with clinical outcome, simplicity, and reliability. Results- The optimal FCASS summed scores from 5 arterial segments: supraclinoid internal carotid artery, A1, A2, M1, and M2. The median (interquartile range) baseline FCASS was 4 (2-6). Of 33 children with follow-up imaging, the maximum FCASS (at any time point) was 7 (5-9). Twenty-four (73%) had FCA progression on follow-up with their maximum FCASS at a median of 8 (5-35.5) days poststroke; their median FCASS increase was 4 (2.5-6). FCASS did not correlate with recurrent arterial ischemic stroke. Maximum (but not baseline) FCASS correlated with 1-year pediatric stroke outcome measures ( P=0.037). Conclusions- Our novel scoring system for FCA severity correlates with neurological outcomes in the VIPS cohort and provides a tool for FCA treatment trials under development.

Abstract
BACKGROUND Acute ischemic stroke (AIS) in pediatric populations accounts for more than half of pediatric strokes and is associated with significant morbidity and mortality. Pediatric AIS can present with nonspecific symptoms or symptoms that mimic alternate pathology. CASE REPORT A 4-month-old female presented to the emergency department for fever, decreased oral intake, and "limp" appearance after antibiotic administration. She was febrile, tachypneic, and hypoxic. Her skin was mottled with 3-s capillary refill, her anterior fontanelle was tense, and she had mute Babinski reflex bilaterally but was moving all extremities. The patient was hyponatremic, thrombocytopenic, and tested positive for influenza A. A computed tomography scan of the brain revealed an acute infarction involving the right frontal, parietal, temporal, and occipital lobes in addition to hyperdensities concerning for thrombosed cortical veins. The patient was transferred for specialty evaluation and was discharged 2 weeks later on levetiracetam. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pediatric AIS can present with nonspecific symptoms that mimic alternate pathology. A high level of suspicion is needed so as not to miss the diagnosis of pediatric AIS in the emergency department. A thorough neurologic assessment is warranted, and subtle abnormalities should be investigated further.

Abstract
Childhood arterial ischemic stroke differs in essential aspects from adult stroke. It is rare, often relatively unknown among laypersons and physicians and the wide variety of age-specific differential diagnoses (stroke mimics) as well as less established care structures often lead to a considerable delay in the diagnosis of stroke. The possible treatment options in childhood are mostly off-label. Experiences in well-established acute treatment modalities in adult stroke, such as thrombolysis and mechanical thrombectomy are therefore limited in children and only based on case reports and case series. The etiological clarification is time-consuming due to the multitude of risk factors which must be considered. Identifying each child's individual risk profile is mandatory for acute treatment and secondary prevention strategies and has an influence on the individual outcome. In addition to the clinical neurological outcome the residual neurological effects of stroke on cognition and behavior are decisive for the integration of the child into its educational, later professional and social environment.
