Abstract
Systemic vascular involvement in children with cerebral arteriopathies is increasingly recognized and often highly morbid. Fibromuscular dysplasia (FMD) represents a cerebral arteriopathy with systemic involvement, commonly affecting the renal and carotid arteries. In adults, FMD diagnosis and classification typically relies on angiographic features, like the 'string-of-beads' appearance, following exclusion of other diseases. Pediatric FMD (pFMD) is considered equivalent to adult FMD although robust evidence for similarities is lacking. We conducted a comprehensive literature review on pFMD and revealed inherent differences between pediatric and adult-onset FMD across various domains including epidemiology, natural history, histopathophysiology, clinical, and radiological features. Although focal arterial lesions are often described in children with FMD, the radiological appearance of 'string-of-beads' is highly nonspecific in children. Furthermore, children predominantly exhibit intimal-type fibroplasia, common in other childhood monogenic arteriopathies. Our findings lend support to the notion that pFMD broadly reflects an undefined heterogenous group of monogenic systemic medium-or-large vessel steno-occlusive arteriopathies rather than a single entity. Recognizing the challenges in categorizing complex morphologies of cerebral arteriopathy using current classifications, we propose a novel term for describing children with cerebral and systemic vascular involvement: 'cerebral and systemic arteriopathy of childhood' (CSA-c). This term aims to streamline patient categorization and, when coupled with advanced vascular imaging and high-throughput genomics, will enhance our comprehension of etiology, and accelerate mechanism-targeted therapeutic developments. Lastly, in light of the high morbidity in children with cerebral and systemic arteriopathies, we suggest that investigating for systemic vascular involvement is important in children with cerebral arteriopathies.

Inflammatory Type Focal Cerebral Arteriopathy of the Posterior Circulation in Children: A Comparative Cohort Study. Stroke 2024; 55:1006-1014. [PMID: 38445467 PMCID: PMC10962439 DOI: 10.1161/strokeaha.123.043562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 01/08/2024] [Accepted: 01/18/2024] [Indexed: 03/07/2024]
Abstract
BACKGROUND Inflammatory type focal cerebral arteriopathy (FCA-i) in the anterior circulation (AC) is well characterized, and the focal cerebral arteriopathy severity score (FCASS) reflects the severity of the disease. We identified cases of FCA-i in the posterior circulation (PC) and adapted the FCASS to describe these cases. METHODS In this comparative cohort study, patients from the Swiss NeuroPaediatric Stroke Registry with ischemic stroke due to FCA-i between January 2000 and December 2018 were analyzed. A comparison between PC and AC cases regarding pediatric National Institutes of Health Stroke Scale score and pediatric stroke outcome measure and FCASS was performed. We estimated infarct size by the modified pediatric Alberta Stroke Program Early Computed Tomography Score in children with AC stroke and the adapted Bernese posterior diffusion-weighted imaging score in the PC. RESULTS Thirty-five children with a median age of 6.3 (interquartile range, 2.7-8.2 [95% CI, 0.9-15.6]; 20 male; 57.1%) years with FCA-i were identified. The total incidence rate was 0.15/100 000/year (95% CI, 0.11-0.21). Six had PC-FCA-i. Time to final FCASS was longer in the PC compared with AC; the evolution of FCASS did not differ. Initial pediatric National Institutes of Health Stroke Scale score was higher in children with FCA-i in the PC with a median of 10.0 (interquartile range, 5.75-21.0) compared with 4.5 (interquartile range, 2.0-8.0) in those with AC-FCA-i. Different from the anterior cases, PC infarct volume did not correlate with higher discharge, maximum, or final FCASS scores (Pearson correlation coefficient [r], 0.25, 0.35, and 0.54). CONCLUSIONS FCA-i also affects the PC. These cases should be included in future investigations into FCA-i. Although it did not correlate with clinical outcomes in our cohort, the modified FCASS may well serve as a marker for the evolution of the arteriopathy in posterior FCA-i.

Abstract
Childhood arterial ischaemic stroke (AIS) is a significant health concern with increasing incidence. This review aims to provide an overview of the current understanding of childhood AIS. The incidence of childhood AIS is on the rise especially in developing countries, likely due to improved awareness and diagnostic capabilities. Aetiology of childhood AIS is multifactorial, with both modifiable risk factors and genetic predisposition playing important roles. Identifying and addressing these risk factors, such as infection, sickle cell disease, and congenital heart defects, is essential in prevention and management. Identifying underlying conditions through genetic testing is important for appropriate management and long-term prognosis. Clinically, distinguishing stroke from stroke mimics can be challenging. Awareness of important stroke mimics, including migraines, seizures, and metabolic disorders, is crucial to avoid misdiagnosis and ensure appropriate treatment. The diagnostic approach to childhood AIS involves a comprehensive "chain of care," including initial assessment, neuroimaging, and laboratory investigations. National guidelines play a pivotal role in standardizing and streamlining the diagnostic process, ensuring prompt and accurate management. Early intervention is critical in the management of childhood AIS. Due to the critical time window, the question if mechanical thrombectomy is feasible and beneficial should be addressed as fast as possible. Early initiation of antiplatelet or anticoagulation therapy and, in select cases, thrombolysis can help restore blood flow and minimize long-term neurological damage. Additionally, rehabilitation should start as soon as possible to optimize recovery and improve functional outcomes. In conclusion, childhood AIS is a growing concern. Understanding the increasing incidence, age distribution, risk factors, clinical presentation, diagnostic approach, and management strategies is crucial for optimized management of these patients.

Abstract
PURPOSE OF REVIEW The primary central nervous system (CNS) vasculitides refers to clinicopathologic disorders that share the histopathology of inflammation of cerebral or spinal blood vessels. Unrecognized and therefore untreated, vasculitis of the CNS results in irreversible injury and disability making these disorders of paramount importance to clinicians. RECENT FINDINGS Headache is an important clue to vasculitic involvement of CNS vessels. CNS vasculitis can be primary, in which only intracranial or spinal vessels are involved in the inflammatory process, or secondary to another known disorder with overlapping systemic involvement. The suspicion of vasculitis based on the history, clinical examination, and laboratory studies warrants prompt evaluation and treatment to prevent cerebral ischemia or infarction. SUMMARY Primary CNS vasculitides can be diagnosed with certainty after intensive evaluation that includes tissue confirmation whenever possible. As in its systemic counterparts, clinicians must choose from among the available immune modulating, suppressive, and targeted immunotherapies to induce and maintain remission status and prevent relapse, tempered by anticipated medication adverse effects.

Abstract
Background and Purpose Arteriopathy is a common etiology for childhood arterial ischemic stroke (AIS). In this study, we aimed to address clinical, demographic, and neuroimaging characteristics and the reversibility of vasculopathy in patients with childhood stroke due to arteriopathy by classifying them according to Childhood AIS Standardized Classification and Diagnostic Evaluation (CASCADE) criteria. Methods We included 15 patients with AIS due to arteriopathy presented between 2013 and 2018. All patients were diagnosed and followed up using magnetic resonance imaging (MRI) studies. All acute AIS patients were classified by acute CASCADE criteria (1-4). Moreover, each group was categorized according to the chronic CASCADE criteria, including progressive, stable, reversible, and indeterminate courses. Results In the study population, CASCADE 2 patients were the most common group, and basal ganglia involvement was the most common involvement in CASCADE 2 patients. Of CASCADE 2 patients, 71.4% received steroids, which was compatible with a favorable outcome. In the study, trauma was present in 33.3% of patients, 60% of which was related to CASCADE 4. In the control visit on month 24, there were neuromotor sequelae of 60%, including hemiparesis, facial paralysis, and decreased fine motor skills; furthermore, the recurrence rate was 20%. Conclusion We strongly emphasize that arteriopathy should be kept in mind in school-age children presenting with hemiparesis and headache. Moyamoya disease must be considered in the differential diagnosis with anterior circulation involvement, while focal cerebral arteriopathy (FCA) in patients with basal ganglia involvement was detected on MRI and dissection in the patients with a history of head-neck injury. We think that steroids have positive influences on neurologic prognosis in patients with FCA.

Abstract
Acute ischemic stroke (AIS) in childhood is defined by a stroke occurring after 28 days of life to 18 years of age. This presents a distinct clinical challenge in terms of both diagnosis and treatment. The overlapping clinical presentations of acute ischemic stroke and its mimics such as migraine with aura, seizure with Todd paresis and encephalitis renders early accurate diagnosis of this time-sensitive condition difficult, with a change in the final diagnosis in up to 40% of patients. Identification of the etiology after establishing the diagnosis of ischemic stroke is paramount for prognostication and treatment decisions. These include cardioembolic, arteriopathy, thrombophilia and inflammatory causes. Magnetic resonance imaging (MRI) plays an indispensable role towards tackling the initial diagnostic dilemma and subsequent evaluation of the underlying etiology, particularly in patients with arteriopathy. Here we present the MRI findings including vessel wall imaging with longitudinal follow-up, which support the diagnosis of focal cerebral arteriopathy-inflammatory type (FCAi) in a pediatric patient.

Abstract
PURPOSE OF REVIEW Uncommon causes of stroke merit specific attention; when clinicians have less common etiologies of stoke in mind, the diagnosis may come more easily. This is key, as optimal management will in many cases differs significantly from "standard" care. RECENT FINDINGS Randomized controlled trials (RCT) on the best medical therapy in the treatment of cervical artery dissection (CeAD) have demonstrated low rates of ischemia with both antiplatelet and vitamin K antagonism. RCT evidence supports the use of anticoagulation with vitamin K antagonism in "high-risk" patients with antiphospholipid antibody syndrome (APLAS), and there is new evidence supporting the utilization of direct oral anticoagulation in malignancy-associated thrombosis. Migraine with aura has been more conclusively linked not only with increased risk of ischemic and hemorrhagic stroke, but also with cardiovascular mortality. Recent literature has surprisingly not provided support the utilization of L-arginine in the treatment of patients with mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS); however, there is evidence at this time that support use of enzyme replacement in patients with Fabry disease. Additional triggers for reversible cerebral vasoconstriction syndrome (RCVS) have been identified, such as capsaicin. Imaging of cerebral blood vessel walls utilizing contrast-enhanced MRA is an emerging modality that may ultimately prove to be very useful in the evaluation of patients with uncommon causes of stroke. A plethora of associations between cerebrovascular disease and COVID-19 have been described. Where pertinent, authors provide additional tips and guidance. Less commonly encountered conditions with updates in diagnosis, and management along with clinical tips are reviewed.

Abstract
Rationale The etiology and pathophysiological mechanisms of moyamoya angiopathy (MMA) remain largely unknown. MMA is a progressive, occlusive cerebrovascular disorder characterized by recurrent ischemic and hemorrhagic strokes; with compensatory formation of an abnormal network of perforating blood vessels that creates a collateral circulation; and by aberrant angiogenesis at the base of the brain. Imbalance of angiogenic and vasculogenic mechanisms has been proposed as a potential cause of MMA. Moyamoya vessels suggest that aberrant angiogenic, arteriogenic, and vasculogenic processes may be involved in the pathophysiology of MMA. Circulating endothelial progenitor cells have been hypothesized to contribute to vascular remodeling in MMA. MMA is associated with increased expression of angiogenic factors and proinflammatory molecules. Systemic inflammation may be related to MMA pathogenesis. Objective This literature review describes the molecular mechanisms associated with cerebrovascular dysfunction, aberrant angiogenesis, and inflammation in MMA and related cerebrovascular diseases along with treatment strategies and future research perspectives. Methods and results References were identified through a systematic computerized search of the medical literature from January 1, 1983, through July 29, 2022, using the PubMed, EMBASE, BIOSIS Previews, CNKI, ISI web of science, and Medline databases and various combinations of the keywords "moyamoya," "angiogenesis," "anastomotic network," "molecular mechanism," "physiology," "pathophysiology," "pathogenesis," "biomarker," "genetics," "signaling pathway," "blood-brain barrier," "endothelial progenitor cells," "endothelial function," "inflammation," "intracranial hemorrhage," and "stroke." Relevant articles and supplemental basic science articles almost exclusively published in English were included. Review of the reference lists of relevant publications for additional sources resulted in 350 publications which met the study inclusion criteria. Detection of growth factors, chemokines, and cytokines in MMA patients suggests the hypothesis of aberrant angiogenesis being involved in MMA pathogenesis. It remains to be ascertained whether these findings are consequences of MMA or are etiological factors of MMA. Conclusions MMA is a heterogeneous disorder, comprising various genotypes and phenotypes, with a complex pathophysiology. Additional research may advance our understanding of the pathophysiology involved in aberrant angiogenesis, arterial stenosis, and the formation of moyamoya collaterals and anastomotic networks. Future research will benefit from researching molecular pathophysiologic mechanisms and the correlation of clinical and basic research results.

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
Cerebral vasculitis is increasingly recognized as a common cause of pediatric arterial stroke. It can present with focal neurological deficits, psychiatric manifestations, seizures, and encephalopathy. The etiopathogenesis of childhood cerebral vasculitis (CCV) is multifactorial, making an inclusive classification challenging. In this review, we describe the common and uncommon CCV with a comprehensive discussion of etiopathogenesis, the role of various imaging modalities, and advanced techniques in diagnosing CCV. We also highlight the implications of relevant clinical, laboratory, and genetic findings to reach the final diagnosis. Based on the clinicoradiological findings, a stepwise diagnostic approach is proposed to facilitate CCV diagnosis and rule out potential mimics. Identification of key clinical manifestations, pertinent blood and cerebrospinal fluid results, and evaluation of central nervous system vessels for common and disease-specific findings will be emphasized. We discuss the role of magnetic resonance imaging, MR angiography, and vessel wall imaging as the imaging investigation of choice, and reservation of catheter angiography as a problem-solving tool. We emphasize the utility of brain and leptomeningeal biopsy for diagnosis and exclusion of imitators and masqueraders.

Abstract
BACKGROUND Focal cerebral arteriopathy (FCA) is a common cause of childhood arterial ischemic stroke in previously healthy children. Although its mechanisms are poorly understood, recent studies have suggested inflammatory processes. Magnetic resonance vessel wall imaging (VWI) is a potential imaging biomarker of inflammation. CASE DESCRIPTION We describe the case of a 7-year-old Japanese girl with right hemiplegia and dysarthria for 3 days. Brain MRI showed acute infarct in the left basal ganglia, and MRA and conventional cerebral angiogram detected vascular stenosis in the left distal internal carotid artery, left M1 and A1 segments. VWI revealed marked vessel wall enhancement and thickening in the left carotid artery, M1, and A2 segments. Based on imaging findings, she was diagnosed with acute ischemic stroke caused by FCA. Because VWI findings were thought to suggest vessel wall inflammation, high-dose steroid therapy was administered in addition to neuroprotective care and antithrombotic therapy. Although her clinical symptoms improved immediately, cerebral arteriopathy worsened on MRA a month after the onset. Subsequently, after 3 months of steroid therapy, vessel wall enhancement on VWI decreased, while arterial stenosis partially improved. At the follow-up 9 months after the onset, she had no recurrent stroke, her arteriopathy had stabilized. DISCUSSION Definitive evidence of inflammatory mechanisms in FCA is limited, and appropriate management and treatment strategies for FCA are undefined. VWI attempts to demonstrate pathologic processes within the vessel wall, and reversible wall enhancement observed in our patient suggested the presence of inflammation. VWI would help in the evaluation of disease activity in FCA. CONCLUSION VWI may contribute to the appropriate diagnosis and treatment for FCA to reflect active inflammation. Further work is needed to assess the utility of VWI in pediatric FCA.

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
Vasculitis refers to heterogeneous clinicopathologic disorders that share the histopathology of inflammation of blood vessels. Unrecognized and therefore untreated, vasculitis of the nervous system leads to pervasive injury and disability, making this a disorder of paramount importance to all clinicians. There has been remarkable progress in the pathogenesis, diagnosis, and treatment of primary CNS and PNS vasculitides, predicated on achievement in primary systemic forms. Primary neurological vasculitides can be diagnosed with assurance after intensive evaluation that incudes tissue confirmation whenever possible. Clinicians must choose from among the available immune modulating, suppressive, and targeted immunotherapies to induce and maintain remission status and prevent relapse, unfortunately without the benefit of RCTs, and tempered by the recognition of anticipated medication side effects. It may be said that efforts to define a disease are attempts to understand the very concept of the disease. This has been especially evident in systemic and neurological disorders associated with vasculitis. For the past 100 years, since the first description of granulomatous angiitis of the brain, the CNS vasculitides have captured the attention of generations of clinical investigators around the globe to reach a better understanding of vasculitides involving the central and peripheral nervous system. Since that time it has become increasingly evident that this will necessitate an international collaborative effort.

Abstract
Pediatric neurovascular pathology directly involves or is in close proximity to the central nervous system (CNS). These vascular pathologies can occur in isolation or in association with broader syndromes. While some vascular pathologies are unique to the pediatric population, the full spectrum of adult neurovascular lesions can also affect children however, may present differently both clinically and on diagnostic imaging. Non-invasive (Ultrasound, CT, MRI) imaging plays a critical role in the diagnosis, treatment planning, and follow-up of vascular lesions involving the CNS. The modality can be chosen based on the age of the child, urgency of diagnosis, and local availability. Each modality has sensitivities and specificities which vary based on the location and imaging findings of a specific neurovascular pathology. In addition to non-invasive options, digital subtraction angiography (DSA) may be used as both a diagnostic and therapeutic imaging method for pediatric vascular lesions of the central nervous system. The diagnosis and management of pediatric cerebrovascular disease requires the close collaboration between pediatricians and pediatric specialists including neuroradiologists, neurologists, neurosurgeons, cardiologists, neurointerventionalists, and anesthesiologists among others. A detailed understanding of imaging findings, natural history, and treatment options is essential to guide and monitor imaging and treatment. The goal of this review is to provide the reader with an overview on pediatric neurovascular pathologies, provide examples of pathognomonic imaging findings, and present a brief review of endovascular treatment options, if applicable.

Abstract
Identifying the etiology of childhood arterial ischemic stroke helps prevent stroke recurrence. In addition, stroke may herald a serious underlying condition requiring treatment, such as acquired heart disease, malignancy, or autoimmune disorder. Evidence-based guidelines exist for adults to identify and treat common risk factors for primary and secondary stroke, including hypertension, diabetes, elevated lipids, atrial fibrillation, and sleep apnea, which are rarely relevant in children. However, guidelines do not exist in pediatrics. Identifying the cause of childhood stroke may be straightforward or may require extensive clinical and neuroimaging expertise, serial evaluations, and reassessment based on the evolving clinical picture. Risk factors may be present but not necessarily causative, or not causative until a triggering event such as infection or anemia occurs. Herein, we describe strategies to determine stroke etiology, including challenges and potential pitfalls.

Abstract
VZV vasculopathy has been associated with granulomatous vasculitis where there is vessel wall damage and transmural inflammation. VZV vasculopathy has been previously called granulomatous angiitis, VZV vasculitis or post-varicella arteriopathy. Intracerebral VZV vasculopathy can occur in children and adults, either after primary infection or after viral reactivation. Where-as varicella primary infection is a common cause of stroke in children, in adults there is an increased risk of stroke after herpes zoster. Here we present a 38-year-old immunocompromised patient who presents to us with multiple cerebral infarcts post primary infection and imaging showing distribution similar to those in children.

Abstract
The field of pediatric stroke has historically been hampered by limited evidence and small patient cohorts. However the landscape of childhood stroke is rapidly changing due in part to increasing awareness of the importance of pediatric stroke and the emergence of dedicated pediatric stroke centers, care pathways, and alert systems. Acute pediatric stroke management hinges on timely diagnosis confirmed by neuroimaging, appropriate consideration of recanalization therapies, implementation of neuroprotective measures, and attention to secondary prevention. Because pediatric stroke is highly heterogenous in etiology, management strategies must be individualized. Determining a child's underlying stroke etiology is essential to appropriately tailoring hyperacute stroke management and determining best approach to secondary prevention. Herein, we review the methods of recognition, diagnosis, management, current knowledge gaps and promising research for pediatric stroke.

Abstract
Varicella zoster virus (VZV) is a Herpesviridae family double-stranded DNA virus that only affects humans. The first clinical manifestation appears to be varicella, typical of childhood. VZV, on the other hand, becomes latent in ganglion neurons throughout the neuroaxis after primary infection. The VZV reactivates and travels along peripheral nerve fibers in the elderly and immunocompromised individuals, resulting in Zoster. It can, however, spread centrally and infect cerebral and extracranial arteries, resulting in vasculopathy, which can lead to transient ischemic attacks, strokes, aneurysms, cavernous sinus thrombosis, giant cell arteritis, and granulomatous aortitis. Although the mechanisms of virus-induced pathological vascular remodeling are not fully understood, recent research indicates that inflammation and dysregulation of ligand-1 programmed death play a significant role. Few studies, on the other hand, have looked into the role of VZV in cardiovascular disease. As a result, the purpose of this review is to examine the relationship between VZV and cardiovascular disease, the efficacy of the vaccine as a protective mechanism, and the target population of heart disease patients who could benefit from vaccination.

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
Objectives: The objective of this study is to analyse detailed clinical presentations, imaging findings, and outcome in a series of 17 cases (n = 17) with neurological complications following acute varicella infection. Methods: It is an observational study on the patients who presented to the neurology outpatient department of our institute with neurological abnormalities following acute varicella infection within the last 3 months. Results: Neuroimaging, either computed tomography or magnetic resonance imaging, cerebrospinal fluid analysis, electroencephalography and nerve conduction studies were performed in all the patients along with other specialized investigations as per clinical context. The age of presentation varied from childhood to middle age (median age was 23 years) and range of clinical spectrum was also wide. Peripheral nervous system involvement was more common in the form of Guillain–Barré syndrome (29.4%) and isolated lower motor neuron facial nerve palsy (23.5%) compared to central nervous system (CNS) involvement. CNS involvement was documented in the form of ataxia (11.76%), myelopathy (17.6%), stroke (5.88%) and encephalitis (5.88%). Conclusion: Chickenpox is a common viral disease and most patients recover without any complication. Although rare, neurological complications following acute varicella infection may have myriad presentations ranging from lower motor neuron facial palsy to life-threatening encephalitis. Compared to other studies, varicella encephalitis and ataxia were not so common in our study group. Response to therapy was uniformly good except in the patients presenting with ataxia. Response was particularly good to central and peripheral demyelinating disorders.

Abstract
INTRODUCTION Moyamoya disease is characterized by progressive stenotic changes in the terminal segment of the internal carotid artery and the development of abnormal vascular networks called moyamoya vessels. The objective of this review was to provide a holistic view of the epidemiology, etiology, clinical findings, treatment, and pathogenesis of moyamoya disease. A literature search was performed in PubMed using the term "moyamoya disease," for articles published until 2021. RESULTS Artificial intelligence (AI) clustering was used to classify the articles into 5 clusters: (1) pathophysiology (23.5%); (2) clinical background (37.3%); (3) imaging (13.2%); (4) treatment (17.3%); and (5) genetics (8.7%). Many articles in the "clinical background" cluster were published from the 1970s. However, in the "treatment" and "genetics" clusters, the articles were published from the 2010s through 2021. In 2011, it was confirmed that a gene called Ringin protein 213 (RNF213) is a susceptibility gene for moyamoya disease. Since then, tremendous progress in genomic, transcriptomic, and epigenetic profiling (e.g., methylation profiling) has resulted in new concepts for classifying moyamoya disease. Our literature survey revealed that the pathogenesis involves aberrations of multiple signaling pathways through genetic mutations and altered gene expression. CONCLUSION We analyzed the content vectors in abstracts using AI, and reviewed the pathophysiology, clinical background, radiological features, treatments, and genetic peculiarity of moyamoya disease.

Abstract
Purpose Vascular complications can be seen in various viral CNS infections. Variable neuro-imaging findings have been described in the literature elucidating the parenchymal changes with vascular involvement. Vessel wall imaging (VWI) can help to detect these vascular involvements. We aimed to describe the role and usefulness of VWI in the evaluation of various viral CNS infections. Methods In this prospective study, we included 15 cases of various diagnosed viral CNS infections (varicella, HIV encephalopathy, HSV encephalitis, Japanese encephalitis, dengue, COVID-19). VWI and time-of-flight MR angiography (TOF MRA) were included in imaging protocol. All cases were evaluated for the presence of cerebral parenchymal changes, vascular enhancement, and vascular stenosis. Results We found infarctions in all 5 cases of varicella, 1 case of HIV encephalopathy, and 1 case of COVID-19 encephalopathy. All these cases also showed vascular enhancement and stenosis on VWI. The rest of the cases, including 1 case of HIV encephalopathy, 3 cases of herpes encephalitis, 2 cases of dengue, and 2 cases of Japanese encephalitis did not have any vascular complication, and also did not show vascular enhancement or stenosis. Conclusion VWI can be useful in the detection of vascular involvement in various viral infections of CNS which show a relatively higher cerebrovascular complication rate like varicella, HIV encephalopathy, and COVID-19. However, VWI may not be useful in the routine evaluation of other viral infections like herpes, dengue, and Japanese encephalitis, which have a very low rate of cerebrovascular complication rate.

Abstract
Moyamoya disease is an idiopathic chronically progressive cerebrovascular disease, which causes both ischemic and hemorrhagic stroke. Genetic studies identified RNF213/Mysterin and GUCY1A3 as disease-causing genes. They were also known to be associated with non-moyamoya intracranial large artery disease, coronary artery disease and pulmonary artery hypertension. This review focused on these two molecules and their strong linker, calcineurin/NFAT signaling and caveolin to understand the pathophysiology of moyamoya disease and related vascular diseases. They are important regulators of lipid metabolism especially lipotoxicity, NF-κB mediated inflammation, and nitric oxide-mediated vascular protection. Although intimal thickening with fibrosis and damaged vascular smooth muscle cells are the distinguishing features of moyamoya disease, origin of the fibrous tissue and the mechanism of smooth muscle cell damages remains not fully elucidated. Endothelial cells and smooth muscle cells have long been a focus of interest, but other vascular components such as immune cells and extracellular matrix also need to be investigated in future studies. Molecular research on moyamoya disease would give us a clue to understand the mechanism preserving vascular stability.

Eur J Radiol 2021; 142:109846. [PMID: 34247031 DOI: 10.1016/j.ejrad.2021.109846] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/29/2021] [Accepted: 07/02/2021] [Indexed: 11/16/2022]
Abstract
Acute ischaemic stroke (AIS) in children is generally considered an up-to-date and controversial topic because its presents significant peculiarities. Focal cerebral arteriopathies (FCA) are a possible cause of AIS in children characterized by an unilateral lesion of the terminal internal cerebral artery (ICA) and proximal segment (M1) of middle cerebral artery (MCA), leading to subocclusion, occasionally with a typical "striate" pattern and a tendency to stability or regression at follow-up. It is unclear whether in FCA the basic lesion is an inflammatory or a dissective arterial pathology. Herein we report a small series of children (<16 yo) with AIS from a FCA who underwent mechanical thrombectomy (MT). We speculate on the angiographic findings suggesting an aetiology of the lesion, and on indications and limits of the currently available treatments.

Abstract
Neurovascular disorders are an important cause of brain injury in the paediatric population, leading to substantial mortality and morbidity. These include ischaemic, haemorrhagic strokes, and cerebral venous sinus thromboses. Despite remarkable improvements in our understanding and management of strokes in general, and in the quality of immediate care and rehabilitation, the outcomes in childhood strokes lag far behind adult strokes. This is a multifaceted problem. There remain several challenges including delays in recognition due to vague clinical presentations, a failure to consider strokes in many cases, delays in obtaining imaging and inadequate imaging when performed, as well as limited evidence and availability for hyper acute intervention in children. Stroke in children is also a vastly different entity to adult strokes, with a unique set of risk factors and often with an underlying cause to be found. This review is by no means exhaustive, but instead aims to provide an overview of the epidemiology, sub-classification and aetiology of paediatric neurovascular disorders, mainly ischaemic, haemorrhagic strokes and cerebral venous sinus thrombosis. We also focus on the risk factors for each of these, the clinical presentation, recommended diagnostic protocol, pertinent imaging findings, as well as the current treatment and follow-up practices.

Abstract
Acute arterial strokes in children are rare but can potentially cause lasting and often permanent neurological deficits. Mechanical thrombectomy has a well-established efficacy and safety profile in adult stroke management, but in the pediatric population, it is yet to be proven efficacious and safe. We present a case of a seven-year-old male who presented with multiple episodes of generalized tonic-clonic seizures after sustaining a neck injury by falling from a trampoline. National Institutes of Health (NIH) on presentation was 21. Neurological exam revealed dilated nonreactive pupils, dysconjugate gaze, severe dysarthria, bilateral ptosis, and movement of upper and lower extremities only to noxious stimuli. Magnetic resonance imaging (MRI) of brain without contrast revealed infarcted areas in the left pons, midbrain, and cerebellar regions. Computed tomographic angiogram (CTA) of head demonstrated left vertebral artery dissection with associated complete occlusion of the distal basilar artery. Successful recanalization was achieved with mechanical thrombectomy six hours after presentation. Mechanical thrombectomy treatment resulted in a significant neurological recovery with NIH of 1. This case supports the growing evidence of the efficacy and safety of mechanical thrombectomy in children.

Unilateral Relapsing Primary Angiitis of the CNS: An Entity Suggesting Differences in the Immune Response Between the Cerebral Hemispheres. NEUROLOGY-NEUROIMMUNOLOGY & NEUROINFLAMMATION 2021; 8:8/2/e936. [PMID: 33402525 PMCID: PMC7862090 DOI: 10.1212/nxi.0000000000000936] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 10/22/2020] [Indexed: 12/26/2022]
Abstract
OBJECTIVE To determine whether studying patients with strictly unilateral relapsing primary angiitis of the CNS (UR-PACNS) can support hemispheric differences in immune response mechanisms, we reviewed characteristics of a group of such patients. METHODS We surveiled our institution for patients with UR-PACNS, after characterizing one such case. We defined UR-PACNS as PACNS with clinical and radiographic relapses strictly recurring in 1 brain hemisphere, with or without hemiatrophy. PACNS must have been biopsy proven. Three total cases were identified at our institution. A literature search for similar reports yielded 4 additional cases. The combined 7 cases were reviewed for demographic, clinical, imaging, and pathologic trends. RESULTS The median age at time of clinical onset among the 7 cases was 26 years (range 10-49 years); 5 were male (71%). All 7 patients presented with seizures. The mean follow-up duration was 7.5 years (4-14.1 years). The annualized relapse rate ranged between 0.2 and 1. UR-PACNS involved the left cerebral hemisphere in 5 of the 7 patients. There was no consistent relationship between the patient's dominant hand and the diseased side. When performed (5 cases), conventional angiogram was nondiagnostic. CSF examination showed nucleated cells and protein levels in normal range in 3 cases and ranged from 6 to 11 cells/μL and 49 to 110 mg/dL in 4 cases, respectively. All cases were diagnosed with lesional biopsy, showing lymphocytic type of vasculitis of the small- and medium-sized vessels. Patients treated with steroids alone showed progression. Induction therapy with cyclophosphamide or rituximab followed by a steroid sparing agent resulted in the most consistent disease remission. CONCLUSIONS Combining our 3 cases with others reported in the literature allows better clinical understanding about this rare and extremely puzzling disease entity. We hypothesize that a functional difference in immune responses, caused by such discrepancies as basal levels of cytokines, asymmetric distribution of microglia, and differences in modulation of the systemic immune functions, rather than a structural antigenic difference, between the right and left brain may explain this phenomenon, but this is speculative.

Abstract
Infections are a frequent cause of cerebral vasculitis, important to diagnose because a specific treatment may be required. Infection-associated vasculitis can be caused by angiotropic pathogens (varicella zoster virus, syphilis, aspergillus). They can be associated with subarachnoidal meningitis (tuberculosis, pyogenic meningitis, cysticercosis). They can appear contiguously to sinuses or orbital infection (aspergillosis, mucormycosis). Finally, they also may be due to an immune mechanism in the context of chronic infections (hepatitis B virus, hepatitis C virus, human immunodeficiency virus). Cerebral vasculitis are severe conditions and their prognosis is directly linked to early recognition and diagnosis. Infectious causes must therefore be systematically considered ahead of cerebral vasculitis, and the appropriate investigations must be determined according to the patient's clinical context. We propose here an update on the infectious causes of cerebral vasculitis, their diagnosis modalities, and therapeutic options.

Abstract
BACKGROUND Focal cerebral arteriopathy (FCA), a major cause of childhood arterial ischemic stroke (AIS), can progress and lead to increased infarct size and/or recurrent stroke. Evaluating treatment options depends on the ability to quantify reliably the degree of stenosis in FCA. AIMS We validated the recently introduced FCA severity score (FCASS) in an independent cohort from the Swiss Neuro-Paediatric Stroke Registry (SNPSR). MATERIALS AND METHODS We included children with FCA who had MR or CT angiography and a Pediatric Stroke Outcome Measure (PSOM) at 6-months and 2-years post-stroke. A paediatric neuroradiologist applied the FCASS and the modified pediatric Alberta Stroke Program Early Computed Tomography Score (ASPECTS), a measure of infarct volume, to all available imaging. Two senior paediatric stroke neurologists and a neuroradiology fellow independently assigned FCASS scores to test interrater reliability. Pairwise correlations between FCASS, pedASPECTS, and PSOM were examined. RESULTS Thirty-two children [median (IQR) age = 5.9 (1.8, 9.6), 19 males] were included. The median maximum FCASS score at any time was 9 (IQR 6, 12; range 3, 16). Larger infarct volume scores correlated with both higher maximum FCASS scores and worse post-stroke outcomes, although we found no direct correlation between FCASS and outcomes. Stroke neurologists tended to assign lower FCASS scores than the neuroradiologist, but interrater reliability was predominantly good. CONCLUSIONS In this independent validation cohort, higher maximum FCASS correlated with greater infarct volume scores that also correlated with worse neurological outcomes. Scoring by non-imaging specialists seems to be valuable, although differences are present.

Associations between Lesion Locations and Stroke Recurrence in Survivors of First-ever Ischemic Stroke: A Prospective Cohort Study. Curr Med Sci 2020; 40:708-718.

Abstract
Several studies have indicated that stroke survivors with multiple lesions or with larger lesion volumes have a higher risk of stroke recurrence. However, the relationship between lesion locations and stroke recurrence is unclear. We conducted a prospective cohort study of first-ever ischemic stroke survivors who were consecutively enrolled from January 2010 to December 2015. Stroke recurrence was assessed every 3 months after post-discharge via telephone interviews by trained interviewers. Lesion locations were obtained from hospital-based MRI or CT scans and classified using two classification systems that were based on cerebral hemisphere or vascular territory and brain anatomical structures. Flexible parametric survival models using the proportional hazards scale (PH model) were used to analyze the time-to-event data. Among 633 survivors, 63.51% (n=402) had anterior circulation ischemia (ACI), and more than half of all ACIs occurred in the subcortex. After a median follow-up of 2.5 years, 117 (18.48%) survivors developed a recurrent stroke. The results of the multivariate PH model showed that survivors with non-brain lesions were at higher risk of recurrence than those with right-side lesions (HR, 2.79; 95%CI, 1.53, 5.08; P=0.001). There was no increase in risk among survivors with left-side lesions (HR, 0.97; 95%CI, 0.53, 1.75; P=0.914) or both-side lesions (HR, 1.24; 95%CI, 0.75, 2.07; P=0.401) compared to those with right-side lesions. Additionally, there were no associations between stroke recurrence and lesion locations that were classified based on vascular territory and brain anatomical structures. It was concluded that first-ever ischemic stroke survivors with non-brain lesion had higher recurrence risk than those with right-side lesion, although no significant associations were found when the lesion locations were classified by vascular territory and brain anatomical structures.

Abstract
OBJECTIVE To determine that children with arterial ischemic stroke (AIS) due to an identifiable arteriopathy are distinct from those without arteriopathy and that each arteriopathy subtype has unique and recognizable clinical features. METHODS We report a large, observational, multicenter cohort of children with AIS, age 1 month to 18 years, enrolled in the International Pediatric Stroke Study from 2003 to 2014. Clinical and demographic differences were compared by use of the Fisher exact test, with linear step-up permutation min-p adjustment for multiple comparisons. Exploratory analyses were conducted to evaluate differences between cases of AIS with and without arteriopathy and between arteriopathy subtypes. RESULTS Of 2,127 children with AIS, 725 (34%) had arteriopathy (median age 7.45 years). Arteriopathy subtypes included dissection (27%), moyamoya (24.5%), focal cerebral arteriopathy-inflammatory subtype (FCA-i; 15%), diffuse cerebral vasculitis (15%), and nonspecific arteriopathy (18.5%). Children with arteriopathic AIS were more likely to present between 6 and 9 years of age (odds ratio [OR] 1.93, p = 0.029) with headache (OR 1.55, p = 0.023), multiple infarctions (OR 2.05, p < 0.001), sickle cell anemia (OR 2.9, p = 0.007), and head/neck trauma (OR 1.93, p = 0.018). Antithrombotic use and stroke recurrence were higher in children with arteriopathy. Among arteriopathy subtypes, dissection was associated with male sex, older age, headache, and anticoagulant use; FCA-i was associated with hemiparesis and single infarcts; moyamoya was associated with seizures and recurrent strokes; and vasculitis was associated with bilateral infarctions. CONCLUSION Specific clinical profiles are associated with cerebral arteriopathies in children with AIS. These observations may be helpful indicators in guiding early diagnosis and defining subgroups who may benefit most from future therapeutic trials.

Abstract
Background and Purpose- Focal cerebral arteriopathy is monophasic inflammatory stenosis of the distal internal carotid artery or the proximal segment of the middle cerebral artery. It is one of the most common causes of acute arterial ischemic stroke in young children but is a less familiar entity for adult neurologists. Methods- We retrospectively reviewed stroke service radiology records at a tertiary referral center from January 2013 to December 2014. Focal cerebral arteriopathy was defined as nonprogressive unifocal and unilateral stenosis/irregularity of the distal internal carotid artery or its proximal branches. Only patients aged 16 to 55 years with stroke were included. Results- There were 5 cases of focal cerebral arteriopathy: 2 males and 3 females. Three cases were from the cohort of 123 acute presentations of young stroke, and 2 cases were outpatient referrals. The mean age (range) was 43 (32-55) years. The majority presented with recurrent transient ischemic attacks/minor strokes within a single vascular territory over days to weeks. All cases had characteristic radiological features. Interval imaging demonstrated resolution in 1 case and improvement in 3 cases. Functional outcome was excellent with discharge modified Rankin Scale score ranging from 0 to 1. Recurrence occurred in 1 case. Conclusions- Focal cerebral arteriopathy is a rare cause of arterial ischemic stroke in young adults. Follow-up intracranial imaging is essential to differentiate from progressive arteriopathies. Evidence-based treatment warrants further investigation. Prognosis is favorable.

Abstract
Non-arteriosclerotic arteriopathies have emerged as important underlying pathomechanism in pediatric arterial ischemic stroke (AIS). The pathogenesis and classification of cerebral arteriopathies in childhood are heterogeneous. Different classifications base on (i) the anatomic site; (ii) the distribution and size of the affected vessel; (iii) the time course, for example, transient vs. progressive, monophasic vs. recurrent; (iv) the putative pathogenesis; (v) the magnetic resonance imaging morphology of the vasculopathies. Inflammation affecting the cerebral vessels is increasingly recognized as common cause of pediatric AIS. Primary cerebral vasculitis or primary angiitis of the central nervous system (CNS) in childhood (cPACNS) is an important differential diagnosis in pediatric AIS. Primary angiitis of the CNS is a rare disorder, and the pathogenesis is poorly understood so far. The current classification of cPACNS is based on the affected cerebral vessel size, the disease course, and angiographic pattern. Two large subtypes are currently recognized comprising large- and medium-sized vessel CNS vasculitis referred to as angiography-positive cPACNS and angiography-negative small vessel cPACNS. As the clinical manifestations of cPACNS are rather diverse, precise diagnosis can be challenging for the treating pediatrician because of the lack of vital laboratory tests or imaging features. Initial misdiagnosis is common because of overlapping phenotypes and pediatric AIS mimics. As untreated cPACNS is associated with a high morbidity and mortality, timely diagnosis, and induction of immunomodulatory and symptomatic therapy are essential. Survival and neurological outcome depend on early diagnosis and prompt therapy. Primary angiitis of the central nervous system in childhood differs in several aspects from primary cerebral angiitis in adults. The aim of this article is to give a brief comprehensive summary on pediatric primary cerebral vasculitis focusing on the clinical perspective regarding the classification, the putative pathogenesis, the disease course, the diagnostic tools, and emerging treatment options. A modified terminology for clinical practice is discussed.

Abstract
The role of Varicella zoster virus (VZV) in neurological illness, particularly cerebrovascular disease, has been increasingly recognized. Primary infection by VZV causes varicella (chickenpox), after which the virus remains latent in neuronal ganglia. Later, during aging or immunosuppression, the virus can reactivate causing zoster (shingles). Virus reactivation can also spread to cerebral arteries causing vasculitis and stroke. Zoster is a recognized risk factor for stroke, but stroke can occur without preceding zoster rash. The diagnosis of VZV cerebral vasculitis is established by abnormal brain imaging and confirmed by presence of viral DNA or anti-VZV antibodies in cerebrospinal fluid. Treatment with acyclovir with or without prednisone is usually recommended. VZV vasculitis is a unique and uncommon stroke mechanism that has been under recognized. Careful diagnostic investigation may be warranted in a subgroup of patients with ischemic stroke to detect VZV vasculitis and initiate appropriate therapy. In the following review, we detail the clinical presentation of VZV vasculitis, diagnostic challenges in VZV detection, and suggest the ways to enhance recognition and treatment of this uncommon disease.

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.

This study aims to describe epidemiological features, clinical characteristics, and neuroimaging data on pediatric posterior circulation arterial ischemic stroke in Switzerland using the population-based Swiss Neuropediatric Stroke Registry.
Methods—
Children aged from 1 month to 16 years presenting with an isolated posterior circulation arterial ischemic stroke between 2000 and 2016 were included. Epidemiology, clinical manifestation, stroke cause, and neuroradiological features were summarized using descriptive statistics. Stroke severity was assessed using the pediatric National Institutes of Health Stroke Scale. Correlation analysis was performed using the Spearman correlation coefficient.
Results—
Forty-three children with posterior circulation arterial ischemic stroke were included (27 boys [62.8%], median age 7.9 years, interquartile range, 5 to 11.7 years). The incidence of posterior circulation arterial ischemic stroke is Switzerland was 0.183/100 000 and represented 16% of all childhood arterial ischemic strokes. Most patients presented with nonspecific neurological complaints, such as headache (58.1%) and nausea/vomiting (46.5%). The most frequent clinical manifestations were ataxia (58.1%) and motor/sensory hemisyndrome (53.5%/51.2%). Unilateral focal cerebral arteriopathy was the most common cause (11 children, 25.6%). Most infarcts were located in the cerebellum (46.5%) and thalamus (39.5%). A shorter diagnostic delay correlated with more severe stroke symptoms at presentation (rho= −0.365,
P
=0.016).
Conclusions—
Pediatric posterior circulation arterial ischemic stroke was caused by focal cerebral arteriopathy in one quarter of the patients in our cohort. The frequently reported nonspecific clinical symptoms, especially when associated with mild neurological findings, risk delaying the diagnosis of stroke. A high index of suspicion and increased awareness are required for timely diagnosis and treatment initiation.

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.
