Adverse motor outcome after paediatric ischaemic stroke: A nationwide cohort study.

Background: Various frequencies of adverse motor outcomes (cerebral palsy and hemiplegia) after paediatric ischaemic stroke have been reported. Few reports on the risks of adverse motor outcomes in nationwide cohorts and contributing risk factors are available.

Objectives: To assess risk of adverse motor outcome and potential risk factors thereof after paediatric ischaemic stroke in a nationwide cohort.

Long-Term Mortality in Children With Ischemic Stroke: A Nationwide Register-Based Cohort Study.

Background And Purpose: Ischemic stroke is a common cause of death in adults, however, mortality after pediatric ischemic stroke is not well explored. We investigate long-term and cause-specific mortality in children with ischemic stroke and their first-degree relatives.

Methods: Through nationwide Swedish registers, we identified 1606 individuals <18 years old with ischemic stroke between 1969 and 2016 and their first-degree relatives (n=5714).

Paediatric ischaemic stroke is a valid diagnosis in the Swedish National Patient Register.

Aim: The Swedish National Patient Register offers unique opportunities for epidemiological research of paediatric ischaemic stroke. We aimed to validate the diagnosis of paediatric ischaemic stroke in the National Patient Register to ensure the quality of future research.

Methods: The PedStroke cohort consists of 1606 individuals aged <18 years with a diagnosis of paediatric ischaemic stroke (ICD-10: I63, I64; ICD-8 and 9: 433, 434, 436) in Swedish national health registers between 1969 and 2016.
