Objective: We developed the Recurrence and Recovery Questionnaire (RRQ) by converting the Pediatric Stroke Outcome Measure (PSOM) to a questionnaire for telephone interview and sought to validate the RRQ in a large cohort.
Method: We analyzed parents' RRQ responses and same-day PSOM assessments for 232 children who had arterial ischemic stroke, cerebral sinovenous thrombosis, or presumed perinatal ischemic stroke. We assessed the agreement and consistency of the PSOM and RRQ, and we identified conditions that contributed to differences between the 2 measures.
Objective: Although acute seizures are common among neonates with arterial ischemic stroke (AIS), the incidence of subsequent seizures is unknown. The goals of this study were to determine the incidence of seizures following hospital discharge after perinatal acute AIS, and to assess lesion characteristics associated with later seizure occurrence.
Methods: Neonates with confirmed acute AIS on MRI were identified through a prospective stroke registry.
Background And Purpose: The objective of this study was to describe the occurrence of hemorrhagic transformation (HT) among children with arterial ischemic stroke within 30 days after symptom onset and to describe clinical factors associated with HT.
Methods: Sixty-three children aged 1 month to 18 years with arterial ischemic stroke between January 2005 and November 2008 were identified from a single-center prospective pediatric stroke registry. All neuroimaging studies within 30 days of stroke were reviewed by a study neuroradiologist.
