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.

[PMID: 38008901 PMCID: PMC10683575 DOI: 10.1177/03000605231213231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 10/23/2023] [Indexed: 11/28/2023] Open
Abstract
OBJECTIVE Due to variability in reports, the aim of this meta-analysis was to evaluate the incidence and risk factors of post-stroke early seizures (ES) and post-stroke epilepsy (PSE). METHODS The MEDLINE, EMBASE and Web of Science databases were searched for post-stroke ES/PSE articles published on any date up to November 2020. Post-stroke ES included seizures occurring within 7 days of stroke, and PSE included at least one unprovoked seizure. Using random effects models, the incidence and risk factors of post-stroke ES and PSE were evaluated. The study was retrospectively registered with INPLASY (INPLASY2023100008). RESULTS Of 128 included studies in total, the incidence of post-stroke ES was 0.07 (95% confidence interval [CI] 0.05, 0.10) and PSE was 0.10 (95% CI 0.08, 0.13). The rates were higher in children than adults. Risk factors for post-stroke ES included hemorrhagic stroke (odds ratio [OR] 2.14, 95% CI 1.44, 3.18), severe strokes (OR 2.68, 95% CI 1.73, 4.14), cortical involvement (OR 3.09, 95% CI 2.11, 4.51) and hemorrhagic transformation (OR 2.70, 95% CI 1.58, 4.60). Risk factors for PSE included severe strokes (OR 4.92, 95% CI 3.43, 7.06), cortical involvement (OR 3.20, 95% CI 2.13, 4.81), anterior circulation infarcts (OR 3.28, 95% CI 1.34, 8.03), hemorrhagic transformation (OR 2.81, 95% CI 1.25, 6.30) and post-stroke ES (OR 7.24, 95% CI 3.73, 14.06). CONCLUSION Understanding the risk factors of post-stroke ES/PSE may identify high-risk individuals who might benefit from prophylactic treatment.

Childs Nerv Syst 2023; 39:2377-2389. [PMID: 37493722 PMCID: PMC10432330 DOI: 10.1007/s00381-023-06086-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 07/15/2023] [Indexed: 07/27/2023]
Abstract
PURPOSE Malignant stroke is a life-threatening emergency, with a high mortality rate (1-3). Despite strong evidence showing decreased morbidity and mortality in the adult population, decompressive hemicraniectomy (DCH) has been scarcely reported in the pediatric stroke population, and its indication remains controversial, while it could be a potential lifesaving option. METHODS AND RESULTS We performed an extensive literature review on pediatric malignant arterial ischemic stroke (pmAIS) and selected 26 articles reporting 97 cases. Gathering the data together, a 67% mortality rate is observed without decompressive therapy, contrasting with a 95.4% survival rate with it. The median modified Rankin score (mRS) is 2.1 after surgery with a mean follow-up of 31.8 months. For the 33% of children who survived without surgery, the mRS is 3 at a mean follow-up of 19 months. As an illustrative case, we report on a 2-year-old girl who presented a cardioembolic right middle cerebral artery stroke with subsequent malignant edema and ongoing cerebral transtentorial herniation in the course of a severe myocarditis requiring ECMO support. A DCH was done 32 h after symptom onset. At the age of 5 years, she exhibits an mRS of 3. CONCLUSION Pediatric stroke with malignant edema is a severe condition with high mortality rate if left untreated and often long-lasting consequences. DCH might minimize the vicious circle of cerebral swelling, increasing intracranial pressure and brain ischemia. Our literature review underscores DCH as an efficient therapeutic measure management of pmAIS even when performed after a significant delay; however, long-lasting morbidities remain high.

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

Abstract
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
BACKGROUND AND OBJECTIVES Ischemic stroke increases the risk of neurodevelopmental disorders; however, the risk of autism is not thoroughly explored. Our aim was to evaluate risk of autism and risk factors for autism in children with pediatric ischemic stroke and in their first-degree relatives. METHODS In this cohort study, individuals with ischemic stroke from 1969 to 2016, <18 years of age, alive 1 week after stroke, and without prior autism were identified in Swedish national registers. Ten matched controls per index individual and all first-degree relatives of index individuals and controls were identified. Conditional Cox regression was used to calculate the risk of autism. Unconditional logistic regression was performed to analyze sex, gestational age, age at stroke diagnoses, comorbid adverse motor outcome, comorbid epilepsy, and a sibling with autism as risk factors for autism in children with ischemic stroke. RESULTS Of the 1,322 index individuals, 46 (3.5%) were diagnosed with autism compared to 161 (1.2%) controls (adjusted hazard ratio [aHR] 3.02, 95% CI 2.15-4.25). There was no significant difference in risk of autism according to age at stroke: perinatal (aHR 2.69, 95% CI 1.44-5.03) and childhood stroke (aHR 3.18, 95% CI 2.12-4.78). The increased risk remained after exclusion of children born preterm or small for gestational age (aHR 3.78, 95% CI 2.55-5.60) and when children with stroke diagnosed from 1997 to 2014 were analyzed (aHR 2.91, 95% CI = 1.95-4.35). Compared to controls, the risk of autism was increased in individuals with ischemic stroke and comorbid epilepsy (aHR 7.05, 95% CI 3.74-13.30), as well as adverse motor outcome (aHR 4.28, 95% CI 2.44-7.51). When individuals with adverse motor outcome and epilepsy were censored, the risk of autism was still increased (aHR 2.37, 95% CI 1.45-3.85). Sex, gestational age, and having a sibling with autism were not associated with autism in individuals with pediatric ischemic stroke. DISCUSSION An increased risk of autism was seen after pediatric ischemic stroke, particularly in individuals with comorbid epilepsy, and could not be explained by being born preterm or small for gestational age. The risk was increased also in individuals free from epilepsy and adverse motor outcome, implying that all children with ischemic stroke should be readily screened for autism if the disorder is suspected.

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
BACKGROUND Childhood stroke is rare and can predispose to post-stroke epilepsy. The purpose of this study was to evaluate long-term quality of life (QoL) in patients with childhood stroke, focusing on epileptic aspects. METHOD This involves a retrospective study of 98 patients with childhood stroke (pre- and neonatal strokes excluded), who had been inpatients between 1986 and 2003 for early rehabilitation. Data were obtained via interviews using a standardized questionnaire: QoL evaluation with KINDL, functional outcome with Barthel Index, and motor handicaps-assessment with modified Rankin Score. RESULTS Forty-nine of 98 patients (31 males, mean follow-up 16 years, range 8-25 years) were included. Six patients passed away (three of sudden unexpected death in epilepsy). At least one epileptic seizure occurred in 27/49 patients (occurrence: 2 days-13 years.; mean 3.3 years.). Epilepsy manifested in 19/49 patients. No correlation was found between the development of epilepsy and the location or etiology of the stroke. The presence of functional independence was significantly higher in seizure-free patients and in patients without epilepsy. For the external assessment (filled in for the patient by the parent/caregiver), there was no significant difference in QoL in patients with and without epilepsy; however, in the in-person KINDL questionnaire a significantly lower QoL was noted in epilepsy patients compared with patients without epilepsy. CONCLUSION One important finding in our study is that in the long-term course 39% of patients developed epilepsy after a childhood stroke. It occurred as late as 13 years after the acute episode and affected the QoL especially in cognitively less handicapped patients.

Abstract
Background and Purpose The risk of epilepsy after stroke has not been thoroughly explored in pediatric ischemic stroke. We examined the risk of epilepsy in children with ischemic stroke as well as in their first-degree relatives. Methods In Swedish National Registers, we identified 1220 children <18 years with pediatric ischemic stroke diagnosed 1969 to 2016, alive 7 days after stroke and with no prior epilepsy. We used 12 155 age- and sex-matched individuals as comparators. All first-degree relatives to index individuals and comparators were also identified. The risk of epilepsy was estimated in children with ischemic stroke and in their first-degree relatives using Cox proportional hazard regression model. Results Through this nationwide population-based study, 219 (18.0%) children with ischemic stroke and 91 (0.7%) comparators were diagnosed with epilepsy during follow-up corresponding to a 27.8-fold increased risk of future epilepsy (95% CI, 21.5–36.0). The risk of epilepsy was still elevated after 20 years (hazard ratio [HR], 7.9 [95% CI, 3.3–19.0]), although the highest HR was seen in the first 6 months (HR, 119.4 [95% CI, 48.0–297.4]). The overall incidence rate of epilepsy was 27.0 per 100 000 person-years (95% CI, 21.1–32.8) after ischemic stroke diagnosed ≤day 28 after birth (perinatal) and 11.6 per 100 000 person-years (95% CI, 9.6–13.5) after ischemic stroke diagnosed ≥day 29 after birth (childhood). Siblings and parents, but not offspring, to children with ischemic stroke were at increased risk of epilepsy (siblings: HR, 1.64 [95% CI, 1.08–2.48] and parents: HR, 1.41 [95% CI, 1.01–1.98]). Conclusions The risk of epilepsy after ischemic stroke in children is increased, especially after perinatal ischemic stroke. The risk of epilepsy was highest during the first 6 months but remained elevated even 20 years after stroke which should be taken into account in future planning for children affected by stroke.

Abstract
INTRODUCTION Although evidence suggests that neurological complications, including seizures and epilepsy, are more common among sickle cell disease (SCD) patients, few studies have assessed the risk factors of developing seizures among SCD patients METHODS: We used a nested case-control study design to compare pediatric and adult SCD patients who experienced seizures with patients who did not experience any seizure regarding clinical and laboratory parameters. We conducted a secondary analysis using the data from the Cooperative Study of Sickle Cell Disease in this study RESULTS: There were 153 out of 2804 (5.5%) pediatric patients who had seizures with a median age of 8.5 (Interquartile range [IQR] = 10.1) years at first seizure and 115 out of 1281 (9.0%) adult patients who had seizures with a median age of 28.0 (IQR = 10.6) years at first seizure. Cerebrovascular accident ([CVA], OR = 5.7, 95% CI = 2.9-11.0), meningitis (OR = 3.6, 95% CI = 1.8-7.2), and eye disease (OR = 3.4, 95% CI = 1.5-8.0) were associated with increased risk of developing seizures among pediatric patients. While CVA (OR = 7.5, 95% CI = 3.5-16.0), meningitis (OR = 5.6, 95% CI = 1.5-20.0), nephrotic syndrome (OR = 3.0, 95% CI = 1.2-7.9), spleen sequestration (OR = 2.7, 95% CI = 1.1-6.3), and pneumonia (OR = 2.1, 95% CI = 1.0-4.4) were associated with increased risk of developing seizures among adult patients CONCLUSION: These findings suggest the need for treatment optimization and regular neurological follow up for SCD patients with these identified risk factors to prevent the development of seizures.

Abstract
Endovascular thrombectomy has played a major role in advancing adult stroke care and may serve a similar role in pediatric stroke care. However, there is a need to develop better evidence and infrastructure for pediatric stroke care. In this work, we review 2 experienced pediatric endovascular thrombectomy programs and examine key design features in both care environments, including a formalized protocol and workflow, integration with an adult endovascular thrombectomy workflow, simplification and automation of workflow steps, pediatric adaptations of stroke imaging, advocacy of pediatric stroke care, and collaboration between providers, among others. These essential features transcend any single hospital environment and may provide an important foundation for other pediatric centers that aim to enhance the care of children with stroke.

Abstract
OBJECTIVES Acute seizures and post-stroke epilepsy have been reported more frequently in patients with pediatric stroke than adults. Acute seizures in the first days of a stroke may deteriorate stroke and ischemia-related neurodegeneration and contribute to the development of post-stroke epilepsy. In this study, we aimed to investigate risk factors for the development of post-stroke epilepsy in children with arterial ischemic stroke. MATERIALS AND METHODS We recruited 86 children with arterial ischemic stroke. We analyzed variables, including age at admission, gender, complaints at presentation, focal or diffuse neurologic signs, neurologic examination findings, laboratory investigations that were conducted at admission with stroke (complete blood cell count, biochemical-infectious-metabolic-immunological investigations, vitamin B12 levels, vitamin D levels), neuroimaging results, etiologies, time of the first seizure, time of remote seizures, and development of neurologic deficit retrospectively. Seizures during the first six hours after stroke onset were defined as 'very early seizures'. 'Early seizures' were referred to seizures during the first 48 h. Patients who experienced two or more seizures that occurred after the acute phase of seizures were classified as 'epileptic.' A binary logistic regression analysis was used to estimate risk factors. RESULTS An acute seizure was detected in 59% and post-stroke epilepsy developed in 41% of our cohort. Binary logistic regression analysis demonstrated that 'very early seizures' increased epilepsy risk six-fold. Epilepsy was 16 times higher in patients with 'early seizures'. Low vitamin D levels were defined as a risk factor for post-stroke epilepsy. CONCLUSION Seizures in the very early period (within the first six hours) are the most significant risk factors for the development of post-stroke epilepsy Further studies regarding seizure prevention and neuroprotective therapies are needed because post-stroke epilepsy will affect long term prognosis in patients with pediatric stroke.

Abstract
Continuous video electroencephalography (CEEG) monitoring of critically ill infants and children has expanded rapidly in recent years. Indications for CEEG include evaluation of patients with altered mental status, characterization of paroxysmal events, and detection of electrographic seizures, including monitoring of patients with limited neurological examination or conditions that put them at high risk for electrographic seizures (e.g., cardiac arrest or extracorporeal membrane oxygenation cannulation). Depending on the inclusion criteria and clinical characteristics of the population studied, the percentage of pediatric patients with electrographic seizures varies from 7% to 46% and with electrographic status epilepticus from 1% to 23%. There is also evidence that epileptiform and background CEEG patterns may provide important information about prognosis in certain clinical populations. Quantitative EEG techniques are emerging as a tool to enhance the value of CEEG to provide real-time bedside data for management and prognosis. Continued research is needed to understand the clinical value of seizure detection and identification of other CEEG patterns on the outcomes of critically ill infants and children.

Abstract
BACKGROUND Childhood stroke causes significant morbidity and mortality. In this study, we aimed to define the presenting findings, causes, risk factors and motor outcomes of our patients. METHODS We retrospectively analysed patients aged from 1 month to 18 years who were diagnosed as having the first onset of stroke between January 2006 and December 2015. Presenting features, causes, risk factors, recurrence rate and motor outcomes were recorded. Motor outcome was evaluated by the gross motor function classification system. RESULTS Forty-seven children were included in the study. Thirty-eight (78.7%) children had an arterial stroke, 9 (19.1%) had a venous stroke. The median age at the time of presentation was 60 months (3-214). Thirty-two patients (68%) presented with a focal neurological sign and 9 presented with seizure (19.1%). Patients who had a venous stroke presented with more diffuse neurological symptoms than those who had an arterial stroke. At least one risk factor for stroke was identified in 74.5% of the patients; the most common causative factor was prothrombotic state seen in 16 patients (33.5%). Stroke recurred in 5 patients (10.6%); coexistence of multiple factors was a risk factor for recurrence. Presenting with seizure was not a facilitator for epilepsy. Thirty-two (68%) patients had a favourable motor outcome. Younger age (24 months versus 114 months) and presenting with focal neurological signs were related to non-favourable motor outcome. CONCLUSION Our cohort demonstrates that most of the children had a risk factor for stroke and have had favourable motor outcome. However, younger age and presenting with focal seizures are related to non-favourable motor outcome.

Abstract
OBJECTIVEHemispherotomy is currently the most frequently performed surgical option for refractory epilepsy associated with large perinatal or childhood ischemic events. Such an approach may lead to good seizure control, but it has inherent functional consequences linked to the disconnection of functional cortices. The authors report on 6 consecutive patients who presented with severe epilepsy associated with hemiplegia due to stroke and who benefitted from a new, stereoelectroencephalography-guided partial disconnection technique.METHODSThe authors developed a new disconnection technique termed "tailored suprainsular partial hemispherotomy" (TSIPH). Disconnection always included premotor and motor cortex with variable anterior and posterior extent.RESULTSAt a mean follow-up of 28 months, there were no deaths and no patient had hydrocephalus. Motor degradation was observed in all patients in the 2 weeks after surgery, but all patients completely recovered. The 6 patients were seizure free (Engel class IA) at the last follow-up. No neuropsychological aggravation was observed.CONCLUSIONSTSIPH appears to be a conservative alternative to classic hemispherotomy, leading to favorable outcome in this series.

Abstract
PURPOSE To identify risk factors for the development of epilepsy after pediatric stroke. METHODS Retrospective analysis of hospital charts of 93 children and adolescents with post-neonatal non-traumatic stroke and a minimum follow-up of two years. Seizures during the first 48 h after onset of stroke symptoms were defined as "early seizures"; when two or more seizures occurred after this period, the patient was classified as "epileptic". RESULTS Early seizures, young age at stroke and MRI evidence of cortical involvement were observed more frequently in the children who developed epilepsy. These factors were, however, significantly interrelated; a stepwise multiple regression analysis in 46/93 patients with complete datasets identified only the occurrence of early seizures as a significant risk factor: 15/19 (79%) children with early seizures developed epilepsy, as opposed to only 7/53 (13%) without early seizures. CONCLUSION Children with stroke who show seizures during the first 48 h after onset of stroke symptoms have a high risk to develop post-stroke epilepsy, whereas in children without early seizures, post-stroke epilepsy is rare.

Abstract
OBJECTIVE To determine the cumulative incidence and clinical predictors of remote symptomatic seizures and epilepsy after pediatric arterial ischemic stroke (AIS). METHODS We performed a retrospective analysis of 218 participants with neonatal AIS (NAIS), presumed perinatal AIS (PPAIS), and childhood AIS (CAIS) from a single-center prospective consecutive cohort enrolled from 2006 to 2014. Medical records were reviewed for timing, semiology, and treatment of acute symptomatic seizures, remote symptomatic seizures (RSS), and epilepsy. Cumulative incidence of RSS and epilepsy were assessed using survival analysis. RESULTS Acute symptomatic seizures occurred in 94% of NAIS (n = 70/74) and 17% of CAIS (n = 18/105). Younger children were more likely to present with seizures at stroke ictus, and acute symptomatic seizures were predictive of later RSS and epilepsy in CAIS. Median follow-up for the entire cohort was 34 months, interquartile range 44.9 months (16.3-61.2). Estimated cumulative incidence of RSS at 2 years was 19% in NAIS, 24% in PPAIS, and 7% in CAIS. Estimated cumulative incidence of epilepsy at 2 years was 11% in NAIS, 19% in PPAIS, and 7% in CAIS. The median time to these outcomes was <2 years in all stroke subtypes. Among participants developing epilepsy (n = 34), seizures were often well-controlled at last follow-up with median Engel class of ≤2 (<1 seizure/month). CONCLUSIONS RSS and epilepsy are important neurologic sequelae of pediatric AIS. Children with perinatal stroke and CAIS with acute symptomatic seizures are at increased risk of these outcomes. These cohorts need further study to identify biomarkers and potential therapeutic targets for epileptogenesis.

Abstract
AIM To determine epilepsy risk factors after pediatric stroke. METHOD A cohort of children with arterial ischemic stroke (birth-18y) was enrolled at 21 centers and followed for 1 year. Acute seizures (≤7d after stroke) and active epilepsy (at least one unprovoked remote seizure plus maintenance anticonvulsant at 1y) were identified. Predictors were determined using logistic regression. RESULTS Among 114 patients (28 neonates and 86 children) enrolled, 26 neonates (93%) and 32 children (37%) had an acute seizure. Acute seizures lasted longer than 5 minutes in 23 patients (40%) and were frequently recurrent: 33 (57%) had 2 to 10 seizures and 11 (19%) had more than 10. Among 109 patients with 1-year follow-up, 11 (10%) had active epilepsy. For each year younger, active epilepsy was 20% more likely (odds ratio [OR] 0.8, 95% confidence interval [CI] 0.6-0.99, p=0.041). Prolonged or recurrent acute seizures also increased epilepsy risk. Each additional 10 minutes of the longest acute seizure increased epilepsy risk fivefold (OR 4.7, 95% CI 1.7-13). Patients with more than 10 acute seizures had a 30-fold increased epilepsy risk (OR 30, 95% CI 2.9-305). INTERPRETATION Pediatric stroke survivors, especially younger children, have a high risk of epilepsy 1 year after stroke. Prolonged or recurrent acute seizures increase epilepsy risk in a dose-dependent manner.

Abstract
AIM To determine clinical/instrumental predictors of symptomatic epilepsy after ischemic stroke in children. MATERIAL AND METHODS One hundred and thirty-six patients, aged 0-15 years, with the diagnosis of ischemic stroke (ICD-10 I63.0-I63.9) were examined. The duration of the study was 18 months - 12 years. Patients were stratified into post-stroke (n=22) and control (n=114) groups, the latter included patients without epilepsy regardless of the presence of convulsive seizures in the acute stage of stroke. Predictors were determined based on EEG and characteristics of convulsive syndrome in the acute stage of stroke. RESULTS AND CONCLUSION The following prognostic criteria were found: generalized type of seizures, focal type of seizures with secondary generalization, epileptiform (peak and/or peak-wave) activity, focal character of epileptiform activity, generalized type of seizures in the combination with slow wave background activity on EEG, generalized type of seizures in the combination with slow wave activity and disorganized activity on EEG.

Abstract
Hemiconvulsion-hemiplegia-epilepsy (HHE) is an uncommon epileptic syndrome that affects young children. Typical management includes early initiation of benzodiazepines to abate the initial seizure activity quickly. Patients in whom epilepsy develops require prolonged use of antiepileptic agents. Herniation due to diffuse cerebral edema from HHE is rare; however, decompressive craniectomy has been described as a lifesaving measure. The authors present the case of a patient in whom a decompressive craniectomy was performed. They advocate a proactive approach in the detection and management of cerebral edema in HHE causing intracranial hypertension. In HHE cases that exhibit radiographic evidence of malignant cerebral edema (although not previously described in this disease, but similar to the setting of stroke and trauma), the authors advocate early neurosurgical consultation and evaluation for insertion of an intracranial pressure monitor for those patients who do not have a reliable neurological examination (i.e., Glasgow Coma Scale score ≤ 8).

Abstract
BACKGROUND There are frequent delays in the diagnosis of acute pediatric ischemic stroke. A screening tool that could increase the suspicion of acute ischemic stroke could aid early recognition and might improve initial care. An earlier study reported that children with acute ischemic stroke have signs that can be recognized with two adult stroke scales. We tested the hypothesis that an adult stroke scale could distinguish children with acute ischemic stroke from children with acute focal neurological deficits not due to stroke. METHODS We retrospectively applied an adult stroke scale to the recorded examinations of 53 children with acute symptomatic acute ischemic stroke and 53 age-matched control subjects who presented with focal neurological deficits. We examined the sensitivity and specificity of the stroke scale and the occurrence of acute seizures as predictors of stroke status. RESULTS The total stroke scale did not differentiate children with acute ischemic stroke from those who had acute deficits from nonstroke causes; however, the presence of arm weakness was significantly associated with stroke cases. Acute seizures were significantly associated with stroke cases. CONCLUSIONS An adult stroke scale is not sensitive or specific to distinguish children with acute ischemic stroke from those with nonstroke focal neurological deficits. The development of a pediatric acute ischemic stroke screening tool should include arm weakness and perhaps acute seizures as core elements. Such a scale must account for the limitations of language in young or intellectually disabled children.

Abstract
Intracranial hemorrhage accounts for about 50% of all pediatric stroke. Studies of term infants with intracranial hemorrhage have shown favorable motor and cognitive outcome. The goal of this study was to examine the risk of developing epilepsy in full-term infants with intracranial hemorrhage. A retrospective study was performed of term neonates (greater than or equal to 37 weeks gestation) with intracranial hemorrhage and confirmed seizures. Fifteen patients with intracranial hemorrhage and neonatal seizures were identified. Four patients did not have follow-up information beyond the neonatal period (1 death, 3 lost to follow-up after initial clinic visit). The average follow-up period for the remaining 11 patients was approximately 22 months. Ten out of the 11 patients (91%) who were followed were seizure-free and off antiepileptic medications. One patient required a ventriculoperitoneal shunt and subsequently developed infantile spasms. The authors found that overall outcome was favorable with respect to development of epilepsy.

Abstract
BACKGROUND AND PURPOSE Cerebral sinovenous thrombosis (CSVT) represents an increasingly recognized cause of pediatric stroke. Our purpose was to assess gender and age differences in the etiology, clinical presentation, and imaging features of CSVT in neonates and older children. METHODS Subjects aged newborn to 18 years diagnosed with CSVT at the Lille university hospital between 2011 and 2014 were included. RESULTS Eleven neonates and 16 non-neonates constituted the study population. The incidence of CSVT was significantly higher in male newborns. Clinical presentation did not vary significantly between the groups. Risk factors were age-dependent, with acute systemic illnesses significantly predominating in neonates (54%), whereas local infections, prothrombotic conditions, and trauma were more common in older children (36, 27, and 27% respectively). No predisposing factor could be identified in 36% of the neonates as compared to less than 5% of the non-neonates. Thrombosis of the deep venous structures was documented in 73% of the neonates whereas involvement of the superficial sinuses was significantly more frequent in the non-neonates group. Venous infarctions and extraparenchymal hemorrhages were significantly more frequent in the neonates group. CONCLUSION Male patients are at higher risk for CSVT than females. In neonates, involvement of the deep venous structures is significantly more common. Brain parenchymal and extraparenchymal changes occur more frequently in this age group than in older children.

Abstract
Emergency physicians are often the first point of contact in children presenting with acute neurological disorders. Differentiating serious disorders, such as stroke, from benign disorders, such as migraine, can be challenging. Clinical assessment influences decision-making, in particular the need for emergent neuroimaging to confirm diagnosis. This review describes the spectrum of disorders causing 'brain attack' symptoms, or acute onset focal neurological dysfunction, with particular emphasis on childhood stroke, because early recognition is essential to improve access to thrombolytic treatments, which have improved outcomes in adults. Clues to diagnosis of specific conditions are discussed. Symptoms and signs, which discriminate stroke from mimics, are described, highlighting differences to adults. Haemorrhagic and ischaemic stroke have different presenting features, which influence choice of the most appropriate imaging modality to maximise diagnostic accuracy. Improvements in the care of children with brain attacks require coordinated approaches and system improvements similar to those developed in adults.

Abstract
Stroke is a rare disease in childhood with an estimated incidence of 1-6/100.000. It has an increasingly recognised impact on child mortality along with its outcomes and effects on quality of life of patients and their families. Clinical presentation and risk factors of paediatric stroke are different to those of adults therefore it can be considered as an independent nosological entity. The relative rarity, the age-related peculiarities and the variety of manifested symptoms makes the diagnosis of paediatric stroke extremely difficult and often delayed. History and clinical examination should investigate underlying diseases or predisposing factors and should take into account the potential territoriality of neurological deficits and the spectrum of differential diagnosis of acute neurological accidents in childhood. Neuroimaging (in particular diffusion weighted magnetic resonance) is the keystone for diagnosis of paediatric stroke and other investigations might be considered according to the clinical condition. Despite substantial advances in paediatric stroke research and clinical care, many unanswered questions remain concerning both its acute treatment and its secondary prevention and rehabilitation so that treatment recommendations are mainly extrapolated from studies on adult population. We have tried to summarize the pathophysiological and clinical characteristics of arterial ischemic stroke in children and the most recent international guidelines and practical directions on how to recognise and manage it in paediatric emergency.

Abstract
AIM The aim of this study was to characterize a group of children with early and late remote seizures, which occurred after arterial ischaemic stroke (AIS), and to find predictors of post-stroke seizures. METHOD The study group, recruited in the Department of Neuropediatrics (Medical University of Silesia, Katowice, Poland), comprised 78 individuals (range 1-18y) who had suffered a stroke: 13 participants had early seizures, occurring up to 7 days after AIS, seven participants had late remote seizures, occurring more than 7 days after AIS, and 58 participants had no seizures. RESULTS Post-stroke epilepsy occurred in 10 patients having post-stroke seizures. Participants affected by late remote seizures were younger, on average, than participants unaffected by seizures. The frequencies of total anterior circulation infarct (TACI) stroke subtype and focal cerebral arteriopathy (FCA) were significantly higher in the late seizure subgroup than in the subgroup without seizures (71% vs 26%, p=0.014, OR 7.17, and 100% vs 51%, p=0.015 respectively). Multivariable Cox analysis showed that age at time of stroke (p=0.027), FCA (p=0.010), and the number of infarct foci (p<0.001) were significant predictors of post-stroke seizures. INTERPRETATION Age at time of stroke, presence of FCA, and number of infarct foci are predictors of post-stroke seizures in Polish paediatric patients.

Abstract
OPINION STATEMENT Children who present with acute neurological symptoms suggestive of a stroke need immediate clinical assessment and urgent neuroimaging to confirm diagnosis. Magnetic resonance imaging (MRI) is the investigation of first choice due to limited sensitivity of computed tomography (CT) for detection of ischaemia. Acute monitoring should include monitoring of blood pressure and body temperature, and neurological observations. Surveillance in a paediatric high dependency or intensive care unit and neurosurgical consultation are mandatory in children with large infarcts at risk of developing malignant oedema or haemorrhagic transformation. Thrombolysis and/or endovascular treatment, whilst not currently approved for use in children, may be considered when stroke diagnosis is confirmed within 4.5 to 6 h, provided there are no contraindications on standard adult criteria. Standard treatment consists of aspirin, but anticoagulation therapy is frequently prescribed in stroke due to cardiac disease and extracranial dissection. Steroids and immunosuppression have a definite place in children with proven vasculitis, but their role in focal arteriopathies is less clear. Decompressive craniotomy should be considered in children with deteriorating consciousness or signs of raised intracranial pressure.

Abstract
Pediatric EEG in the intensive care unit (ICU) requires specific technical requirements in order to yield relevant data depending upon clinical scenario: diagnosis of electroclinical or subclinical seizures, their quantification before and after therapeutic changes and sometimes evaluation of severity of cortical dysfunction. The urgent nature of these indications implies the rapid set-up of the EEG system by qualified staff and possibility of maintaining the electrodes in place during long periods of time. Various techniques are available today for EEG monitoring, the interpretation of which depends on the contribution of an experienced physician. Among recent techniques, those most commonly used are trend curves obtained via signal analysis such as amplitude EEG (a-EEG) and density spectral array (DSA) or compressed spectral array (CSA). Trend curves enable the digital creation of a display graph containing several hours of transformed and compressed EEG recorded data. Visualized on one sole display graph, these trend curves can facilitate the identification of very slow changes in EEG background activity and their variation (alertness cycles, changes linked to treatment administrations) as well as seizure patterns and their quantification. In this chapter, we propose a brief overview of monitoring techniques, followed by a review of the various data yielded by EEG monitoring as well as the relevance of this type of management; finally, detailed clinical indications will be discussed after thorough analysis of the literature.

Abstract
BACKGROUND Cardiac disease is a leading cause of stroke in children, yet limited data support the current stroke prevention and treatment recommendations. A multidisciplinary panel of clinicians was convened in February 2014 by the International Pediatric Stroke Study group to identify knowledge gaps and prioritize clinical research efforts for children with cardiac disease and stroke. RESULTS Significant knowledge gaps exist, including a lack of data on stroke incidence, predictors, primary and secondary stroke prevention, hyperacute treatment, and outcome in children with cardiac disease. Commonly used diagnostic techniques including brain computed tomography and ultrasound have low rates of stroke detection, and diagnosis is frequently delayed. The challenges of research studies in this population include epidemiologic barriers to research such as small patient numbers, heterogeneity of cardiac disease, and coexistence of multiple risk factors. Based on stroke burden and study feasibility, studies involving mechanical circulatory support, single ventricle patients, early stroke detection strategies, and understanding secondary stroke risk factors and prevention are the highest research priorities over the next 5-10 years. The development of large-scale multicenter and multispecialty collaborative research is a critical next step. The designation of centers of expertise will assist in clinical care and research. CONCLUSIONS There is an urgent need for additional research to improve the quality of evidence in guideline recommendations for cardiogenic stroke in children. Although significant barriers to clinical research exist, multicenter and multispecialty collaboration is an important step toward advancing clinical care and research for children with cardiac disease and stroke.

Abstract
PURPOSE OF REVIEW To discuss the use of continuous video-electroencephalographic (cEEG) monitoring among critically ill children at risk for electrographic seizures and status epilepticus. RECENT FINDINGS Recent reports have demonstrated the growing, but heterogeneous, use of cEEG monitoring among North American pediatric institutions, and provided evidence for the high prevalence of subclinical seizures, particularly among encephalopathic patients with acute brain injury. Increasing seizure burden and status epilepticus have been shown to be independently associated with worse short-term and long-term outcomes. SUMMARY Certain high-risk children frequently experience electrographic seizures and status epilepticus, often without clinical signs, necessitating the use of cEEG monitoring for their diagnosis and management. Although an increasing electrographic seizure burden and status epilepticus are independently associated with worse outcome, further studies are needed to determine whether aggressive use of antiepileptic drugs to reduce seizure burden can improve outcome.

Abstract
Electroencephalography allows the functional analysis of electrical brain cortical activity and is the gold standard for analyzing electrophysiological processes involved in epilepsy but also in several other dysfunctions of the central nervous system. Morphological imaging yields complementary data, yet it cannot replace the essential functional analysis tool that is EEG. Furthermore, EEG has the great advantage of being non-invasive, easy to perform and allows control tests when follow-up is necessary, even at the patient's bedside. Faced with the advances in knowledge, techniques and indications, the Société de Neurophysiologie Clinique de Langue Française (SNCLF) and the Ligue Française Contre l'Épilepsie (LFCE) found it necessary to provide an update on EEG recommendations. This article will review the methodology applied to this work, refine the various topics detailed in the following chapters. It will go over the summary of recommendations for each of these chapters and underline proposals for writing an EEG report. Some questions could not be answered by the review of the literature; in those cases, an expert advice was given by the working and reading groups in addition to the guidelines.

Abstract
The incidence of perinatal stroke is high, similar to that in the elderly, and produces a significant morbidity and severe long-term neurologic and cognitive deficits, including cerebral palsy, epilepsy, neuropsychological impairments, and behavioral disorders. Emerging clinical data and data from experimental models of cerebral ischemia in neonatal rodents have shown that the pathophysiology of perinatal brain damage is multifactorial. These studies have revealed that, far from just being a smaller version of the adult brain, the neonatal brain is unique with a very particular and age-dependent responsiveness to hypoxia-ischemia and focal arterial stroke. In this review, we discuss fundamental clinical aspects of perinatal stroke as well as some of the most recent and relevant findings regarding the susceptibility of specific brain cell populations to injury, the dynamics and the mechanisms of neuronal cell death in injured neonates, the responses of neonatal blood-brain barrier to stroke in relation to systemic and local inflammation, and the long-term effects of stroke on angiogenesis and neurogenesis. Finally, we address translational strategies currently being considered for neonatal stroke as well as treatments that might effectively enhance repair later after injury.

Abstract
Post-stroke seizures and epilepsy in children are a common but understudied complication. In this retrospective cohort study, the medical records of 65 children aged 0 to 18 years were analyzed to assess the risk of post-stroke seizures, detect the prevalence of post-stroke epilepsy, and ascertain which risk factors are associated with this condition in children. Forty-two patients (64.6%) had epileptic seizures following stroke (35 early, 7 late-onset), with most (78.5%) occurring in the first 24 hours. Nineteen children (29.2%) developed post-stroke epilepsy, which was significantly more common among patients with late-onset seizures (P = .034). There was a significant association between cortical involvement and development of epilepsy (P = .01). After Poisson regression, the relative risk of epilepsy was calculated as 2.4 in children with late-onset post-stroke seizures (95% confidence interval, 1.4-3.9; P = .001) and 3.7 in children with cortical involvement (95% confidence interval, 1.4-9.7; P = .009).

Fox CK, Glass HC, Sidney S, Lowenstein DH, Fullerton HJ. Acute seizures predict epilepsy after childhood stroke. Ann Neurol 2013; 74:249-56. [PMID: 23613472 PMCID: PMC3830669 DOI: 10.1002/ana.23916] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2013] [Revised: 04/08/2013] [Accepted: 04/19/2013] [Indexed: 12/29/2022]
Abstract
OBJECTIVE To determine incidence rates and predictors of epilepsy after childhood stroke and compare these to published estimates of 3 to 5% cumulative epilepsy incidence by 5 years poststroke in adults. METHODS In a retrospective population-based study of children with stroke (29 days-19 years) in an integrated health care system (1993-2007), poststroke seizures were identified through electronic searches and confirmed by chart review. Stroke and seizure characteristics were abstracted from medical records. Survival analysis was used to determine rates and predictors of remote seizures and active epilepsy (anticonvulsant treatment for remote seizure within prior 6 months) at last follow-up. RESULTS From a population of 2.5 million children, we identified 305 stroke cases. Over a median follow-up of 4.1 years (interquartile range = 1.8-6.8), 49 children had a first unprovoked remote seizure. The average annual incidence rate of first remote seizure was 4.4% (95% confidence interval [CI] = 3.3-5.8) with a cumulative risk of 16% (95% CI = 12-21) at 5 years and 33% (95% CI = 23-46) at 10 years poststroke. The cumulative risk of active epilepsy was 13% (95% CI = 9-18) at 5 years and 30% (95% CI = 20-44) at 10 years. Acute seizures at the time of stroke predicted development of active epilepsy (hazard ratio = 4.2, 95% CI = 2.2-8.1). At last follow-up, ⅓ of the children with active epilepsy had a recent breakthrough seizure despite anticonvulsant usage. INTERPRETATION Unlike adults, children are uniquely vulnerable to epilepsy after stroke. Children with acute seizures at the time of stroke are at particularly high risk.

Abstract
Seizures and stroke are both common neurologic conditions, but when they occur in close temporal proximity they produce much more concern than either does alone. The stroke specialist (and the family) fear that convulsions will worsen the stroke because of acute hypertension and airway compromise, and the epileptologist is concerned that these acute seizures are the harbingers of later epilepsy. Other less commonly recognized but important aspects of this relationship are that subclinical seizures worsen some forms of stroke, and some anticonvulsants may have more adverse effects on stroke patients than they do in other groups. In surveying the connections between these two conditions, I have attempted to address seven questions. For some questions, there are data to help provide an answer; for others, there is only opinion; and for a maddening few, newer research is making older suggestions less certain.

Abstract
Pediatric neurocritical care is an emerging multidisciplinary field of medicine and a new frontier in pediatric critical care and pediatric neurology. Central to pediatric neurocritical care is the goal of improving outcomes in critically ill pediatric patients with neurological illness or injury and limiting secondary brain injury through optimal critical care delivery and the support of brain function. There is a pressing need for evidence based guidelines in pediatric neurocritical care, notably in pediatric traumatic brain injury and pediatric stroke. These diseases have distinct clinical and pathophysiological features that distinguish them from their adult counterparts and prevent the direct translation of the adult experience to pediatric patients. Increased attention is also being paid to the broader application of neuromonitoring and neuroprotective strategies in the pediatric intensive care unit, in both primary neurological and primary non-neurological disease states. Although much can be learned from the adult experience, there are important differences in the critically ill pediatric population and in the circumstances that surround the emergence of neurocritical care in pediatrics.
