Background Pediatric stroke outcome studies are often cross sectional in design. Prospective information regarding the clinical course following diagnosis is lacking, but may inform clinical management beyond the acute period. Aims To describe the outcome of arterial ischemic stroke in infants, children and adolescents at one-month and sixmonths post-stroke across health domains, and explore the relationship between lesion characteristics and early outcome with six-month adaptive behavior. Methods A single center prospective longitudinal study at a tertiary level children's hospital. Recruitment was undertaken from December 2007 to January 2012. Participants were children aged birth to 18 years presenting acutely with first diagnosed arterial ischemic stroke. Lesion characteristics on brain imaging were classified. Children were grouped according to age at diagnosis for analysis (neonates vs. those aged >30 days). Results In 50 children with a median age of 47 months at diagnosis, sensorimotor impairments were most evident upon neurological examination acutely, especially in the older children. At both one-month and six-months motor functioning was significantly impaired in the older age group but no significant cognitive or language sequelae were identified. Lesion characteristics alone were not associated with six-month adaptive behavior outcomes. Conclusions For patients surviving arterial ischemic stroke, the most significant clinical consequences both acutely and at sixmonths, are sensorimotor impairments, particularly evident in the older children. In contrast cognitive or language sequelae were not identified. Long-term surveillance is required to describe clinical course and rehabilitation needs, particularly for neonates and infants.
