    Abstract:
    Child stroke is a major cause of death in children, although limited information exists on neurobehavioral functioning of stroke survivors. Executive function (important for goal-directed behavior) is thought to be vulnerable to early insults such as stroke because of its widespread representation in the immature brain. This study investigated the impact of lesion location on executive skills. Twenty-eight children diagnosed with stroke at least 18 months before assessment were recruited. Lesion characteristics were coded from magnetic resonance imaging (MRI) scans. Neurobehavioral assessment focused on cognitive and everyday executive skills. Deficits were found in the context of overall normal intellectual functioning (M = 91.60; SD = 19.40). Generally, insults involving frontal and extra-frontal regions impacted equally on cognitive performance. Everyday deficits were marginally more prominent following frontal insult. Subcortical frontal lesions were associated with impairments in everyday executive skills. Results provide further support for the diffuse representation of executive function in the immature brain.
