Abstract
Childhood cerebral vasculitis is a condition that affects the blood vessels in the brain of children and is rare but life-threatening. Imaging plays a crucial role in the diagnosis and monitoring of the disease. This article describes the classification, diagnostic algorithm, and various imaging modalities used in the evaluation of childhood cerebral vasculitis and the imaging findings associated with primary and secondary vasculitis. Understanding the imaging features of this condition can assist in early diagnosis, effective treatment, and improve outcomes.

Abstract
Streptococcus pneumoniae (S. Pneumoniae) is a common cause of bacterial meningitis in the pediatric population, but rarely causes complications such as encephalitis, abscess, and seizures with the prompt initiation of proper antimicrobial therapy. In this report, we present a rare and severe case of S. Pneumoniae meningoencephalitis in a full term 6-month-old which progressed to multiple cerebral and cerebellar infarcts with concomitant cerebellar tonsillar herniation and hypercarbic respiratory failure requiring intubation and mechanical ventilation despite early initiation of antibiotics. Given the patient's clinical status and poor neurological prognosis, the family eventually opted for palliative extubation.

Abstract
Meningitis caused by bacteria, which is an inflammation of the meninges affecting the pia, arachnoid, and subarachnoid space, is still one of the leading causes of death and morbidity in infants and young children. Neisseria meningitidis, group B streptococcus (GBS), Haemophilus influenzae type B (Hib), Listeria monocytogenes, and Streptococcus pneumoniae have been found to be the most frequent causative agents. Infants and children can have modest, fluctuating, non-specific, or even absent clinical signs of bacterial meningitis. They may include bulging fontanelles, vomiting, diarrhea, respiratory distress, hypothermia, lethargy, irritability, poor feeding, and fever in babies. In this case report, an 18-month-old child presented to a local hospital with complaints of multiple episodes of high-grade fever. After 10 days, his symptoms worsened and he experienced two episodes of seizures at one-day intervals at night. He was taken to Acharya Vinoba Bhave Rural Hospital for further management. Blood investigations revealed seropositive results for dengue virus infection. On MRI and CT scan, it was diagnosed as an old case of subdural hematoma in the right frontotemporal region of the brain. The patient was on intravenous ceftriaxone and phenytoin. Gross motor developmental milestones in children with meningitis can be improved with early integrative neurophysiotherapy and a goal-oriented therapeutic regimen that includes mobility exercises, proprioceptive neuromuscular facilitation techniques, positioning, oromotor retraining, neurodevelopmental techniques, and balance and coordination retraining. A complex case presents with bacterial meningitis, hydrocephalus, and seizure disorder. The bacterial infection inflames the protective membranes of the brain, causing hydrocephalus. Increased cerebrospinal fluid puts pressure on the brain, leading to seizures. Managing these interconnected conditions requires a multidisciplinary approach making it unique, involving infectious disease, neurology, and neurosurgery expertise.

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
Alazami syndrome is a rare autosomal recessive neurodevelopmental disorder due to loss-of-function variants in the La ribonucleoprotein 7 (LARP7) gene. Children with Alazami syndrome are most often affected by a combination of primordial dwarfism, intellectual disability, and distinctive facial features. Previous cases have been primarily found in consanguineous families from the Middle East, Asia, and North Africa. We present a 21-month-old Caucasian male from the Midwest United States with nonconsanguineous parents who presented with frequently reported findings of unusual facial features, poor growth, cardiac and genitourinary findings, and developmental delay; less-frequently reported findings, including transient erythroblastopenia of childhood (TEC) and immune deficiency; and never-before reported findings of periventricular nodular heterotopia and stroke. He developed stroke during a hospitalization for Hemophilus influenzae meningitis. The possible contributions of LARP7 to TEC, immune deficiency, brain malformation, and stroke are discussed. Guidelines for the care of Alazami patients are proposed.

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
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
Stroke is one of the primary causes of mortality and morbidity worldwide. It can be ischemic or hemorrhagic, and the former can be due to an in-situ thrombus or a distant embolus. Despite being a rare cause, stroke can also be caused in the setting of infection. Bacterial agents are the most common cause of stroke, among other infectious agents. Until the antibiotic era, rheumatic heart disease was a predisposing risk factor of infective endocarditis. VZV is the most common cause of strokes in pediatric and adult populations. Cryptococcus and Candida spp are the most common yeasts involved in CNS infections, especially in immunocompromised patients. In COVID-19 patients, ischemic strokes are more common than hemorrhagic strokes. In this review, we will discuss the most common infectious agents, with particular emphasis on COVID-19.

Abstract
BACKGROUND Neonatal bacterial meningitis has high rates of morbidity and mortality. Early clinical signs and neuroimaging suggest adverse outcomes, but little is known about their combined predictive properties. We evaluated the combination of findings most associated with death and neurodevelopmental impairment. METHODS Single-center retrospective cohort study of term and late preterm neonates with bacterial meningitis. Predictors of death and neurodevelopmental impairment were identified on univariate analysis and incorporated into Lasso models to identify variables best predicting adverse outcomes. RESULTS Of 103 neonates, 6 died acutely; 30% of survivors had neurodevelopmental impairment. Clinical variables (seizures, pressor support) predicted death and neurodevelopmental impairment better than the neuroimaging or combined findings (area under the curve 0.88 vs 0.79 and 0.83, respectively). Among survivors, neuroimaging findings (cerebrovascular lesions, ventriculomegaly) predicted neurodevelopmental impairment better than clinical or combined findings (area under the curve 0.82 vs 0.80 and 0.77, respectively). CONCLUSIONS Seizures are important predictors of adverse outcomes in neonatal bacterial meningitis. Among survivors, neuroimaging findings help predict neurodevelopmental impairment.

Abstract
OBJECTIVE To describe the etiology of childhood arterial-ischemic stroke from a developing country and assess short-term neurologic outcome. METHODS Prospective observational study. Consecutive children between the age of >28 days to <12 years, admitted with the diagnosis of arterial-ischemic stroke were enrolled during the study period from January 2017 to December 2018. Short-term neurologic outcome was assessed with Pediatric Cerebral Performance Category (PCPC) scale and Pediatric Stroke Outcome Measure (PSOM). RESULTS We enrolled 76 children with arterial-ischemic stroke, with a median age of 24 months (interquartile range 12-69), and 43 (57%) were boys. The most common risk factor for childhood arterial-ischemic stroke was arteriopathy in 59 (77%), followed by cardiovascular disorder in 12 (16%) children. Among 59 children with arteriopathy, 32 (42%) had infection-associated arteriopathies, 10 (13%) had mineralizing angiopathy, 10 (13%) had moyamoya disease. Pediatric stroke risk factors were classified according to Pediatric Stroke Classification and CASCADE primary classification. Short-term neurologic outcome was assessed at 3 months in 62 (82%) survivors. Among stroke survivors, 33 (61%) had sensory-motor deficits, and 24 (39%) had severe neurologic disability (PCPC ≥ 4). The presence of fever, encephalopathy, low Glasgow coma score at presentation, seizures, and infection-associated arteriopathy predicted severe neurologic disability at follow-up. CONCLUSION The risk factors for pediatric arterial-ischemic stroke are different from developed countries in our cohort. Infection-associated arteriopathies, mineralizing angiopathy, and moyamoya disease are the most common risk factors in our cohort. Two-thirds of pediatric stroke survivors have neurologic disability at short-term follow-up.

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.

[PMID: 34204785 PMCID: PMC8296207 DOI: 10.3390/ijerph18126386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 06/04/2021] [Accepted: 06/07/2021] [Indexed: 11/16/2022]
Abstract
Although corticosteroids can serve as an effective anti-inflammatory adjuvant therapy, the role of adjunctive steroid therapy in pediatric bacterial meningitis in Taiwan remains under-investigated. Cases of acute bacterial meningitis, aged between 1 month and 20 years, were divided into a steroid group (empirical antibiotics with adjunctive steroid therapy) and a non-steroid group (empirical antibiotics only). Data were identified from the annual hospitalization discharge claims of the National Health Insurance Research Database using the International Classification of Diseases, Ninth Revision codes. Of the 8083 episodes enrolled in this study, 26% (2122/8083) and 74% (5961/8083) were divided into the steroid and non-steroid groups, respectively. The fatality rates were 7.9% in the steroid group and 1.7% in the non-steroid group during hospitalization (p < 0.0001). In the steroid and non-steroid groups, the median length of hospital stay was 13 and 6 days, respectively (p < 0.0001). Medical costs (median (interquartile range)) of hospitalization were 77,941 (26,647–237,540) and 26,653 (14,287–53,421) New Taiwan dollars in the steroid and non-steroid groups, respectively (p < 0.0001). The steroid group had a more fulminant course at baseline, a higher fatality rate, length of hospital stay, and medical cost of hospitalization. Therefore, the beneficial effects of the adjunctive use of corticosteroids in pediatric bacterial meningitis are inconclusive, and additional prospective multicenter investigations are required to clarify this issue.

Abstract
In this review, we provide the data on the modern use of different MRI modalities and computer tomography (CT) as diagnostic and prognostic tools for meningitis of various etiology, first of all, bacterial purulent meningitis. Each of these techniques has its own field of application depending on the stage of the disease and the patients condition (necessity of intensive care procedures, ventilation support). The opinions on the diagnostic value of CT and structural MRI data differ and depend on the etiology and phase of the inflammatory process. In the recent years, the techniques of multiparametric MRI are widely implemented in the practice. Beside structural MRI, they include diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI) and MR spectroscopy (MRS), as well as studies with artificial contrast; there are some reports that these modalities are more effective as a diagnostic tool in meningitis. Thus, the use of multiparametric MRI techniques and CT with contrast is promising and justified for the diagnostics of patients with bacterial purulent meningitis from the viewpoint of enhanced sensitivity.

Abstract
Bacterial meningitis is a devastating infection, with a case fatality rate of up to 30% and 50% of survivors developing neurological complications. These include short-term complications such as focal neurological deficit and subdural effusion, and long-term complications such as hearing loss, seizures, cognitive impairment and hydrocephalus. Complications develop due to bacterial toxin release and the host immune response, which lead to neuronal damage. Factors associated with increased risk of developing neurological complications include young age, delayed presentation and Streptococcus pneumoniae as an etiologic agent. Vaccination is the primary method of preventing bacterial meningitis and therefore its complications. There are three vaccine preventable causes: Haemophilus influenzae type b (Hib), S. pneumoniae, and Neisseria meningitidis. Starting antibiotics without delay is also critical to reduce the risk of neurological complications. Additionally, early adjuvant corticosteroid use in Hib meningitis reduces the risk of hearing loss and severe neurological complications.

Abstract
Perinatal stroke is a focal vascular brain injury that occurs from the fetal period to 28 days of postnatal age. With an overall incidence of up to 1 in 1,000 live births, the most focused lifetime risk for stroke occurs near birth. Perinatal stroke can be classified by the timing of diagnosis, vessel involvement, and type of injury. Timing of diagnosis may be in the acute neonatal period or retrospectively after a period of normal development, followed by abnormal neurologic findings, with the injury presumed to have occurred around the time of birth. Strokes may be arterial or venous, ischemic, and/or hemorrhagic. Within these classifications, 6 perinatal stroke diseases are recognizable, based on clinical and radiographic features. Morbidity is high in perinatal stroke, because it accounts for most cases of hemiparetic cerebral palsy, with disability lasting a lifetime. Additional complications include disorders of sensation and vision, language delays, cognitive and learning deficits, epilepsy, and mental health consequences that affect the entire family. Advances in neonatal neurocritical care may afford opportunity to minimize brain injury and improve outcomes. In the chronic timeframe, progress made in neuroimaging and brain mapping is revealing the developmental plasticity that occurs, informing new avenues for neurorehabilitation. This review will summarize the diagnosis and management of each perinatal stroke disease, highlighting their similarities and distinctions and emphasizing a patient- and family-centered approach to management.

Abstract
Cerebral vasculitis is a serious complication of bacterial meningitis that can cause significant morbidity and mortality due to stroke. Currently, there are no treatment guidelines or safety and efficacy studies on the management of cerebral vasculitis in this context. Herein, we report a case of a previously well 11-year-old girl who presented with acute otitis media that progressed to mastoiditis and fulminant meningitis. Group A Streptococcus was found in blood and ear-fluid cultures (lumbar puncture was unsuccessful). Her decreased level of consciousness persisted despite appropriate antimicrobial treatment, and repeat MRI revealed extensive large vessel cerebral vasculitis. Based on expert opinion and a presumed inflammatory mechanism, her cerebral vasculitis was treated with 7 days of pulse intravenous methylprednisolone followed by oral prednisone taper. She was also treated with intravenous heparin. Following these therapies, she improved clinically and radiographically with no adverse events. She continues to undergo rehabilitation with improvement.

Abstract
BACKGROUND Perinatal stroke encompasses multiple disease-specific cerebrovascular syndromes that cause lifelong neurodevelopmental morbidity for millions worldwide. Acute presentations include neonatal arterial ischemic stroke (NAIS), neonatal cerebral sinovenous thrombosis, and neonatal hemorrhagic stroke (NHS). Delayed presentations include arterial presumed perinatal ischemic stroke, periventricular venous infarction, and presumed perinatal hemorrhagic stroke. Our objective was to define the birth prevalence of all subtypes of perinatal stroke by using a population-based cohort. METHODS The Alberta Perinatal Stroke Project is a research cohort established in 2008 in southern Alberta, Canada, with prospective (2008-2017) and retrospective (1990-2008) enrollment leveraging universal health care at a single tertiary care pediatric center. The primary outcome was the estimated birth prevalence of each perinatal stroke syndrome, secondary outcomes were birth prevalence over time, sex ratios, and change in age at diagnosis. Analysis included Poisson regression, Wilcoxon rank test, and Fisher exact test. RESULTS The overall estimated birth prevalence of term-born perinatal stroke was 1:1100. The estimated birth prevalence was 1:3000 for NAIS, 1:7900 for arterial presumed perinatal ischemic stroke, 1:6000 for periventricular venous infarction, 1:9100 for cerebral sinovenous thrombosis, 1:6800 for NHS, and 1:65000 for presumed perinatal hemorrhagic stroke. The apparent birth prevalence of NAIS and NHS increased over time. There were more males affected than females. The age at diagnosis decreased for late-presenting stroke types. CONCLUSIONS The estimated birth prevalence of term perinatal stroke is higher than previous estimates, which may be explained by population-based sampling of disease-specific states. This emphasizes the need for further studies to better understand the disease-specific pathophysiology to improve treatment and prevention strategies.

Abstract
Arachnoid cysts are relatively common and benign intraarachnoid membrane outpouchings containing CSF-like fluid. The majority of arachnoid cysts remain stable and asymptomatic and do not require intervention in the pediatric population. Here, the authors present the first reported case of an infected arachnoid cyst in a pediatric patient resulting in severe vasospasm of the left terminal internal carotid artery, left A1 segment, and left M1 branches with a left middle cerebral artery infarct. Their experience suggests that close monitoring is warranted for this condition and that the pediatric population may be at higher risk for vasospasm.

Abstract
Introduction In countries where Haemophilus influenzae type B vaccine is used, Streptococcus pneumoniae is the most common cause of bacterial meningitis in young children and notable cause of morbidity/mortality. The authors present material of magnetic resonance imaging (MRI) of patients with pneumococcal meningitis from archive of Department of Diagnostic Imaging of Institute of Mother and Child in Warsaw. Materials and methods We performed 27 brain MRI scans and 1 follow-up computed tomography (CT) in 10 children (2 girls and 8 boys) aged from neonate to 5 years at disease onset with proven pneumococcal infection. Results Follow-up period range was 0–12 years. Two children underwent only one MRI, one of them died before follow-up and the other was lost from further observation. There was one case of relatively benign disease course with mild changes on MRI. In another seemingly benign case, acute transient hydrocephalus was observed. Six children developed hydrocephalus, and two required ventriculoperitoneal shunting complicated by neuroinfection, shunt malfunction and revisions. Two patients developed epilepsy. In six children, spastic paresis of various severity was diagnosed, up to quadriplegia in one who is under the longest observation (>12 years) and survived in vegetative state. Three other children suffer from delayed psychomotor development to severe intellectual disability. Conclusions MRI shows perfectly the degree of central nervous system (CNS) damage during and after pneumococcal invasion. Despite appropriate treatment, disease course may be unpredictably serious. Attempts to eliminate the obligation to vaccinate are extremely irresponsible taking into account potential danger of death, vegetative state or another form of severe damage to CNS. Social and financial costs of care of survivors are very high with shunts placements and changes, (neuro)infections, rehabilitation, families breakdown, etc.

Abstract
PURPOSE OF REVIEW Stroke continues to be a leading cause of debility in the world. Infections have been associated with stroke, but are not considered as directly causal, and so they are not often included in the traditional stroke workup and management. They are especially important in patients with stroke of undetermined etiology, and in certain patient populations, such as young patients without traditional risk factors, and immunocompromised patients. RECENT FINDINGS There has been strong evidence for infectious conditions, such as endocarditis, and pathogens, such as varicella zoster in stroke causation, and more supportive evidence is surfacing in recent years of several organisms increasing the stroke risk or being directly causal in stroke. The evidence also seems to be pointing to the role of inflammation in increasing the risk of stroke via accelerated atherosclerosis, vasculitis and vasculopathy. SUMMARY Infectious causes should be considered in the differential and work up of stroke in certain patient populations and appropriate treatments need to be initiated to minimize adverse stroke-related outcomes.

Abstract
Perinatal strokes are a diverse but specific group of focal cerebrovascular injuries that occur early in brain development and affect an estimated 5 million people worldwide. The objective of this review is to describe the epidemiology, clinical presentations, pathophysiology, outcomes, and management for the 6 subtypes of perinatal stroke. Some perinatal strokes are symptomatic in the first days of life, typically with seizures, including neonatal arterial ischemic stroke, neonatal hemorrhagic stroke, and cerebral sinovenous thrombosis. The remaining subtypes present in the first year of life or later, usually with motor asymmetry and include arterial presumed perinatal ischemic stroke, presumed perinatal hemorrhagic stroke, and in utero periventricular venous infarction. The consequences of these injuries include cerebral palsy, epilepsy, and cognitive and behavioral challenges, in addition to the psychosocial impact on families. While there have been significant advances in understanding mechanisms of both injury and recovery, there is still a great deal to learn regarding causation and the optimization of outcomes.
