Although there have been significant theoretical advances in the field of child neuropsychology, developmental features of adolescence have received less attention. Progress in clinical practice is restricted due to a lack of well-standardized, developmentally appropriate assessment techniques. This article addresses these issues in relation to executive(More)
This study addressed the clinical and construct validity of the Behavior Rating Inventory of Executive Function. (BRIEF: Gioia, Isquith, Guy, & Kenworthy, 2000), a questionnaire designed to tap behavioral aspects of executive functions in children. BRIEF profiles in early treated phenylketonuria (PKU; n=44), early treated hydrocephalus (n=45), frontal focal(More)
Until recently, the impact of early brain insult (EBI) has been considered to be less significant than for later brain injuries, consistent with the notion that the young brain is more flexible and able to reorganize in the context of brain insult. This study aimed to evaluate this notion by comparing cognitive and behavioural outcomes for children(More)
OBJECTIVE To describe neuropsychological profiles and their relationship to metabolic control in children with type 1 diabetes 6 years after the onset of disease. RESEARCH DESIGN AND METHODS Children with type 1 diabetes (n = 90), aged 6-17 years, who had previously been assessed soon after diagnosis and 2 years later, were reevaluated 6 years after the(More)
Problem solving skills were investigated in children with focal lesions using the Tower of London test (TOL; Shallice, 1982). The scoring procedure was elaborated from previous studies to delineate separate processes contributing to overall performance in children. Thirty-one children with focal frontal pathology, 18 children with focal pathology in other(More)
In this study, the development of concept generation and mental flexibility was investigated in 84 Australian children between 3 and 7 years of age, using the Object Classification Task for Children (OCTC), a newly developed executive function test for use with young children. On this task, which was adapted from the Concept Generation Test (Levine, Stuss,(More)
Despite the potential impact on development, few studies have examined the influence of prefrontal lesions occurring prior to maturation of the central nervous system. This study investigates the effect of prefrontal lesions in general, as well as the impact of lesion laterality, with respect to attentional abilities. The sample comprised 36 children with(More)
Traditionally early brain insult (EBI) has been considered to have better outcome than later injury, consistent with the notion that the young brain is flexible and able to reorganize. Recent research findings question this view, suggesting that EBI might lead to poorer outcome than brain insult at any other age. Exploring this early vulnerability(More)
While it is generally agreed that outcome following cerebral insult during childhood differs from that seen following similar pathology in adulthood, the specific relationship between timing of cerebral lesion and outcome, and the mechanism associated with observed neurobehavioral changes, remains controversial. Data from children with focal lesions(More)
Recovery from acute disseminated encephalomyelitis in childhood appears relatively uneventful, at least when looking at functional recovery parameters such as neurologic outcome. However, neuropsychology literature suggests that relatively transient illnesses affecting the central nervous system are associated with cognitive and social sequelae,(More)
