Objectives:To investigate the impact of age at pediatric arterial ischemic stroke on long-term cognitive outcome in order to identify patients particularly at risk for the development of cognitive long-term cognitive sequelae.Methods:This cross-sectional study included patients in the chronic phase of stroke (> 2 years after stroke) previously diagnosed with neonatal or childhood arterial ischemic stroke and a control group. Participants with active epilepsy, severe learning difficulties, or behavioral problems hindering the cognitive assessment were excluded. Several cognitive domains, including intelligence, executive functions (working memory, inhibition, and cognitive flexibility), processing speed, memory, letter fluency, and visual-motor skills were assessed with neuropsychological tests. Cognitive long-term outcome was compared across patients after neonatal stroke (stroke between 0 and 28 days of life), early childhood stroke (stroke between 29 days and < 6 years) and late childhood stroke (stroke between ≥ 6 and < 16 years).Results:52 patients after neonatal or childhood arterial ischemic stroke (median age: 15.3 years, IQR = 10.6 – 18.7) and 49 healthy controls (median age: 13.6 years, IQR = 9.8 – 17.2) met the inclusion criteria. Cognitive outcome was significantly worse in the pediatric stroke group compared to the control group. A non-linear effect of age at stroke (irrespective of lesion size and lesion location) was found for cognitive flexibility, processing speed, and verbal learning with early childhood stroke (29 days to < 6 years) showing significantly worse cognitive outcome compared to neonatal or late childhood stroke (p < .05, FDR-corrected).Conclusion:Age at stroke is an important factor for post-stroke recovery and modulates long-term cognitive outcome irrespective of lesion size and lesion location. Children after early childhood stroke are at particular risk for alterations of long-term cognitive functions.

Objective. To assess the prevalence of markers of preclinical vascular, kidney and brain damage in the survivors of the Leningrad Siege (SLS) in the long-term period of life, as well as to determine a possible connection with starvation in the prenatal period and early childhood.Design and methods. A prospective cohort study of 305 SLS was initiated in 2009–2011. In a control sex- and age-matched group we recruited people born in the same time period in other regions of the Soviet Union and permanently residing in Leningrad after the World War II (n = 51). At the second visit in 2013–2014, 252 residents of besieged Leningrad were examined (the response rate was 82,6 %). Blood pressure measurement and anthropometry were performed according to standard methods. The laboratory examination included the assessment of fasting glucose, lipids, and creatinine with the calculation of the glomerular filtration rate (GFR) according to the CKD-EPI formula. The concentration of albumin and creatinine was determined, and the albumin-creatinine ratio was calculated. All patients underwent assessment of the pulse wave velocity by the applanation tonometry (SphygmoCor, AtCor, Australia), cardio-ankle vascular index (CAVI) and ankle-brachial index (VaSera VS 1500, FukudaDenshi, Japan). For cognitive assessment, the Mini-Mental State Examination (MMSE) scale was used.Results. The analysis included data of 184 residents of besieged Leningrad (52 males (28,3 %) and 132 females (71,7 %), average age 74,7 years old) divided into three groups depending on the age period during the Siege: 132 people in the first group (late childhood and adolescents), 28 people in the early childhood group, 24 people in the third “intrauterine” group. The control group included 44 people: 13 males (29,5 %) and 31 females (70,5 %), average age 75,5 years old. The survivors of the besieged Leningrad showed lower anthropometric characteristics — lower weight (p = 0,005) and body mass index (p = 0,004) compared with the control group. There were no differences in the prevalence of vascular, renal and cerebral lesions. The lowest arterial stiffness according to the CAVI index was detected in the “intrauterine” group compared to early, late childhood and adolescent groups (p = 0,015). Renal dysfunction was detected only in the first group (late childhood and adolescents).Conclusions. The residents of the besieged Leningrad demonstrate low prevalence of renal dysfunction and arteriosclerosis of the large arteries and atherosclerosis of the peripheral arteries, as well as preserved cognitive function. The increased arterial stiffness and decreased GFR in SLS who experienced the siege in late childhood and adolescence are most likely due to the older age.

Hintergrund Die zeitliche Verzögerung zwischen Symptombeginn und Diagnose ist eine Herausforderung in der Behandlung von Kindern mit arteriell ischämischem Schlaganfall. Frühere Studien zur klinischen Präsentation beschäftigten sich v. a. mit kumulativen Symptomen. Zielsetzung Ziel dieser Studie ist es, mögliche Symptommuster aufzuzeigen. Methoden In einer aktiven Beobachtungsstudie zwischen 01/2015 und 12/2016 (ESPED-Studie) wurden Kinder mit Erstdiagnose eines arteriell ischämischen Schlaganfalls eingeschlossen. Isoliert auftretende Erstsymptome wurden verschiedenen Symptomkombinationen gegenübergestellt. Zudem wurde untersucht, inwieweit ein als „akut“ oder „progredient“ klassifiziertes Auftreten der Symptome Rückschlüsse auf die zugrundeliegende Ätiologie erlaubt. Ergebnisse Es wurden 99 Kinder in die Studie eingeschlossen. Unabhängig vom Alter traten überwiegend fokale Symptome auf (86%). Krampfanfälle als Initialsymptom wurden insbesondere bei Säuglingen beschrieben (67%), wohin-gegen diffuse, unspezifische Symptome vor allem bei Vorschulkindern (38%) und älteren Kindern (59%) auftraten. Isoliert traten fokale Symptome bei 37 Kindern auf, 48 Kinder zeigten zusätzlich unspezifische Symptome, darunter auch 9 Kinder mit Krampfanfällen. Isolierte unspezifische Symptome zeigten sich lediglich bei 7 Kindern, 2 Kinder wurden nur mit Krampfanfällen symptomatisch. Die Akuität des Symptombeginns wurde bei 53/78 als „akut“ und bei “25/78 Fällen als „progredient“ klassifiziert, lieferte jedoch keinen Hinweis auf die zugrundeliegende Ätiologie. Schlussfolgerung Jedes neue fokal neurologische Defizit sollte unabhängig vom Auftreten (isoliert oder kombiniert, akut oder progredient) an einen kindlichen Schlaganfall denken lassen. Background Time delay between onset of clinical symptoms and diagnosis is a challenge in childhood arterial ischemic stroke. Most previous studies reported cumulative symptoms. Objective We attempted to identify typical symptom patterns and assessed their emergence in childhood stroke. Methods Prospective active surveillance in ESPED, a hospital based Pediatric Surveillance Unit for rare diseases in Germany, between January 2015 and December 2016. Case definition: first diagnosis of a radiologically confirmed arterial ischemic stroke. Symptom patterns were identified as occurring in isolation or in combination. We distinguished acute vs. progressive onset. We ascertained risk factors to identify the possible etiology. Results 99 children with childhood arterial ischemic stroke were reported. Focal symptoms were the predominant presenting feature (86%), independent of age. Seizures were more often seen in infants < 1 year (67%), whereas diffuse symptoms were more present in pre-school children (38%) and older children (59%). 37 children had focal features alone and 48 additional non-specific features, including 9 with seizures. Isolated non-specific features accounted for 7 cases, and 2 children had (focal) seizures as the only symptom. In 77% of all cases at least one risk factor was identified. The emergence of symptoms was acute in 53/78 cases and progressive in 25/78 cases. The pattern of emergence was unrelated to the underlying etiology. Conclusions Any new focal neurological deficit in isolation, or associated with seizures or further non-specific symptoms should alert to childhood stroke.

Stroke In Young Adults

Lipoprotein (a) is a cholesterol-rich plasma lipoprotein with a lipid composition similar to that of low-density lipoproteins (LDL). Many prospective and case-control studies identified elevated levels of lipoprotein (a) as a risk factor for premature myocardial infarction and stroke. Elevated lipoprotein (a) has been identified as a genetically determined risk factor for stroke in young adults, but only preliminary data are available on its role as a risk factor for ischemic stroke in infants and children. Fifty two children with arterial ischemic stroke and 78 age- and sex-matched healthy children were studied. Data of this study indicate that 26.9% of children with arterial ischemic stroke had high lipoprotein (a) levels in comparison with the age matched healthy control group. Measurement of lipoprotein (a) should be included in screening programs performed in young patients suffering not only from venous thromboembolism but also arterial ischemic stroke, in addition to other thrombophilic factors.

Purpose: Perinatal ischemic stroke (PIS) is a frequent cause for perinatal brain structure defects resulting in epilepsy, cerebral palsy and disability. Since the severity of symptoms is variable, the aim of this study was to evaluate the outcome of children with PIS and seizures/epilepsy to aid parental counseling and therapy decisions. Material: We studied retrospectively patients with arterial PIS and structural epilepsy or seizures in the newborn treated at a single center in 2000-2019. Specifically, signs and symptoms of cerebral palsy (CP), developmental and motor delay, epilepsy and thrombophilia were assessed. Results: From the identified 69 individuals with arterial PIS, we only included the 50 patients (64% male) who had structural epilepsy at the time of investigation or previously in their medical history.The mean age of the included patients was 7.1 years (range 0.08-22) at last consultation. Infarct localisation was predominantly unilateral (86%), left sided (58%) and affecting the middle cerebral artery (94%). Genetic thrombophilia was identified in 52% of the patients examined with genetic testing. More than half of the individuals had CP (52%), and 38.5% had a cognitive outcome below average. First seizures occurred in the neonatal period in 58% of patients and developed into drug-refractory epilepsy in 24.1%. Children with late-onset of epilepsy were twice as likely to develop drug-refractory epilepsy (52.4%). Discussion: Our study shows that patients with PIS and seizures as common sequela often also develop CP. Children with later onset of epilepsy have a worse outcome. Patients with seizure onset in the neonatal period and reccuring seizures have a good response to treatment. Therefore, early diagnosis, follow-up examination and adequate therapy are important. Most children need intensive physiotherapy and speech therapy; however, participation in life is usually age-appropriate.

The Impact

Ischemic stroke is a leading cause of death and disability. Diabetes not only increases the risk of stroke, it also worsens the outcomes, increases the risk of hemorrhagic transformation (HT) and impairs recovery after stroke. It is well established that young females are more protected and show better outcomes than males after stroke. However, the impact of diabetes on long term recovery after stroke in both sexes was not clear. Accordingly, this study tested the hypothesis that diabetes impairs long term functional recovery after ischemic stroke in a sex independent manner. Methods: Diabetes was induced in male and female Wistar rats using high fat diet and low dose streptozotocin (30 mg/Kg). After 8 weeks of diabetes, animals were subjected to embolic stroke. Male and female Wistar normoglycemic age matched rats were used as controls. Motor (composite score: 14 best outcome and adhesive removal-ART) and cognitive (novel object recognition, NOR) deficits were assessed at day1, 3, 7 and 14. Results: Female control animals had better outcomes compared to the males. Mortality was higher in diabetic animals, especially in males. The neurological deficits were greater in diabetic animals with no difference between males and females. Conclusion: Diabetes impaired functional and cognitive outcome and recovery after ischemic stroke in a sex independent manner.

Primary Injury

Background: Neonatal arterial ischemic stroke (NAIS) is a leading cause of brain injury and cerebral palsy. Diffusion-weighted imaging (DWI) has revolutionized NAIS diagnosis and outcome prognostication. Diaschisis refers to changes in brain areas functionally connected but structurally remote from primary injury. We hypothesized that acute DWI can demonstrate cerebral diaschisis and evaluated associations with outcome. Methods: Subjects were identified from a prospective, population-based research cohort (Calgary Pediatric Stroke Program). Inclusion criteria were unilateral middle cerebral artery NAIS, DWI MRI within 10 days of birth, and >12-month follow-up (Pediatric Stroke Outcome Measure, PSOM). Diaschisis was quantified using a validated software method. Diaschisis-scores were corrected for infarct size and compared to outcomes (Mann-Whitney). Results: From 20 eligible NAIS, 2 were excluded for image quality. Of 18 remaining, 16 (89%) demonstrated diaschisis. Thalamus (88%) was most often involved. Age at imaging was not associated with diaschisis. Long-term outcomes available on 13 (81%) demonstrated no association between diaschisis score and PSOM categories. Conclusion: Cerebral diaschisis occurs in NAIS and can be quantified with DWI. Occurrence is common and should not be mistaken for additional infarction. Determining additional clinical significance will depend on larger samples with long-term outcomes.

Abstract Purpose of Review A novel permanent carotid filter device for percutaneous implantation was developed for the purpose of stroke prevention. In this review, we cover rationale, existing preclinical and clinical data, and potential future directions for research using such a device. Recent Findings The Vine™ filter was assessed for safety in sheep and in 2 observational human studies, the completed CAPTURE 1 (n = 25) and the ongoing CAPTURE 2 (planned n = 100). CAPTURE 1 has shown high procedural and long-term implant safety. A control group was not available for comparison. Summary A mechanical filter for permanent stroke prevention can be implanted bilaterally in the common carotid artery safely and efficiently. A randomized trial is planned for 2021 (n = 3500, INTERCEPT) to demonstrate superiority of a filter + anticoagulation strategy over anticoagulation alone in patients at high risk for ischemic stroke.

Executive Attention Network

We investigated attentional outcome after childhood stroke and orthopedic diagnosis in medical controls. Twenty-nine children with focal stroke lesions and individually matched children with clubfoot or scoliosis were studied with standardized attention and neuroimaging assessments. Stroke lesions were quite varied in location and commonly involved regions implicated in Posner's model of attention networks. Children with stroke lesions performed significantly more poorly regarding attention function compared with controls. Performance on the Starry Night, a test demanding alerting and sensory-orienting but not executive attention function, was significantly associated with lesion size in the alerting and sensory-orienting networks but not the executive attention network. Furthermore, earlier age at lesion acquisition was significantly associated with poorer attention function even when lesion size was controlled. These findings support the theory of dissociable networks of attention and add to evidence from studies of children with diffuse and focal brain damage that early insults are associated with worse long-term outcomes in many domains of neuropsychological function. In addition, these results may provide clues towards the understanding of mechanisms underlying attention in children. (JINS, 2004,10, 976–986.)

Objective: Neurocognitive dysfunction is a common feature of bipolar disorder even in euthymia, and psychopharmacological treatment could have an effect on cognition. Long-term prescription of benzodiazepines in bipolar disorder is a common practice, and their effect on neurocognition has not been well studied in this population. The aim of this study was to evaluate the impact of concomitant benzodiazepine long-term use on neurocognitive function in stable euthymic bipolar disorder patients. Methods: Seventy-three euthymic bipolar disorder outpatients and 40 healthy individuals were assessed using a neurocognitive battery. Patients were classified in two groups according to the presence of benzodiazepines in their treatment: the benzodiazepine group ( n = 34) and the non- benzodiazepine group ( n = 39). Neurocognitive performance was compared between the groups using a multivariate analysis of covariance, considering age, number of depressive episodes, adjuvant antipsychotic drugs, Young Mania Rating Scale score and Hamilton Depression Rating Scale score as covariates. Results: Both bipolar disorder groups (benzodiazepine and non-benzodiazepine) showed an impairment in memory domains (Immediate Visual Memory [ p = 0.013], Working Memory [ p < 0.001], and Letter-Number Sequence [ p < 0.001] from the Wechsler Memory Scale-Revised-III) and slower processing speed functions (Stroop Colour [ p < 0.001]) relative to the control group. Nevertheless, the benzodiazepine group showed a greater impairment in executive functions (Conceptual Level Responses [ p = 0.024] from the Wisconsin Card Sorting Test and Frontal Assessment Battery [ p = 0.042]). Conclusion: Although memory and processing speed impairments were found in bipolar disorder, regardless of their benzodiazepine treatment, benzodiazepine users presented additional neurocognitive impairments in terms of executive functioning. These findings support restricted prescription of benzodiazepines in individuals with bipolar disorder.

ABSTRACT Objective: To explore the influence of infarct location on long-term functional outcome following a first-ever arterial ischemic stroke (AIS) in non-neonate children. Method: The MRIs of 39 children with AIS (median age 5.38 years; 36% girls; mean follow-up time 5.87 years) were prospectively evaluated. Infarct location was classified as the absence or presence of subcortical involvement. Functional outcome was measured using the modified Rankin scale (mRS) for children after the follow-up assessment. We utilized multivariate logistic regression models to estimate the odds ratios (ORs) for the outcome while adjusting for age, sex, infarct size and middle cerebral artery territory involvement (significance < 0.05). Results: Both infarcts ≥ 4% of total brain volume (OR 9.92; CI 1.76 – 55.9; p 0.009) and the presence of subcortical involvement (OR 8.36; CI 1.76 – 53.6; p 0.025) independently increased the risk of marked functional impairment (mRS 3 to 5). Conclusion: Infarct extension and location can help predict the extent of disability after childhood AIS.
