Aim: The aim of this study was to obtain information about neurological and cognitive outcome for a population-based group of children after paediatric ischaemic stroke., Methods: Data from the Swiss neuropaediatric stroke registry (SNPSR), from 1.1.2000 to 1.7.2002, including children (AIS 1) and neonates (AIS 2). At 18-24 months after a stroke, a follow-up examination was performed including a history, neurological and neuropsychological assessment., Results: 33/48 children (22 AIS 1, 11 AIS 2) participated in the study. Neurological outcome was good in 16/33. After childhood stroke mean IQ levels were normal (94), but 6 children had IQ < 85 (50-82) and neuropsychological problems were present in 75%. Performance IQ (93) was reduced compared to verbal IQ (101, p = 0.121) due to problems in the domain of processing speed (89.5); auditory short-term memory was especially affected. Effects on school career were common. Outcome was worse in children after right-sided infarction. Children suffering from stroke in mid-childhood had the best prognosis. There was no clear relationship between outcome and localisation of the lesion. After neonatal stroke 7/11 children showed normal development and epilepsy indicated a worse prognosis in the remaining 4., Conclusion: After paediatric stroke neuropsychological problems are present in about 75% of children. Younger age at stroke as well as an emergence of epilepsy were predictors for worse prognosis.

We report the results of three years of the population-based, prospective Swiss NeuroPaediatric Stroke Registry (SNPSR) of children (up to 16 years) with childhood arterial ischaemic stroke (AIS1), neonatal stroke (AIS2), or symptomatic sinus venous thrombosis (SVT). Data on risk factors (RF), presentation, diagnostic work-up, localisation, and short-term neurological outcome were collected. 80 children (54 males) have been included, 40 AIS1, 23 AIS2, and 17 SVT. The data presented will be concentrated on AIS. The presentation for AIS1 was hemiparesis in 77% and cerebellar symptoms and seizures in 20%, respectively. AIS2 presented in 83% with seizures and in 38% with abnormality of muscle tone. Two or more RF were detected in 54%, one RF in 35%. The most prominent RF for AIS1 were infections (40%), followed by cardiopathies and coagulopathies (25% each). AIS2 were frequently related to birth problems. Neurological outcomes in AIS1 and AIS2 were moderate/severe in 45 % and 32 %, respectively. The outcome correlated significantly with the size of infarction (p = 0.013) and age at stroke (p = 0.027). The overall mortality was 6%. Paediatric stroke is a multiple risk problem, which leads to important long-term sequelae.

Aim: Paediatric arterial ischaemic stroke can lead to reduced quality of life (QoL). It is important to identify predictors of QoL to support recovery. We examined long-term QoL after arterial ischaemic stroke concerning different variables.Method: Children registered in the Swiss Neuropediatric Stroke Registry and suffering from arterial ischaemic stroke between 2000 and 2008 were included. Two years post-stroke, assessments included intelligence quotient tests for cognitive impairment and modified Rankin Scale (mRS) for neurological impairment; 5 years post-stroke, the Kidscreen-27 was used for QoL, DSM-IV criteria screening was used for attention deficits, and the ABILHAND-Kids was used for manual motor skills. Age at stroke, sex, socioeconomic status, lesion characteristics, neuropsychological and motor outcome, and mRS were correlated with QoL measures.Results: Seventy children were examined (49 males, 21 females; mean age 7y 2wks). Age at stroke, sex, socioeconomic status, and lesion characteristics did not influence QoL; IQ below average and attention deficits partially influenced QoL. The highest predictive value for QoL was found for manual motor impairment (p=0.002) and mRS scores (p=0.013). Combined motor, cognitive, and attention impairment negatively affected QoL (p=0.001).Interpretation: Neurological and cognitive impairments after paediatric arterial ischaemic stroke negatively influence QoL. Children with motor and neurological problems, as well as those with combined motor, cognitive, and attention problems, are at higher risk for low QoL. [ABSTRACT FROM AUTHOR]
