BACKGROUND/AIM To describe prevalence, subtypes and severity of cerebral palsy (CP) in Norway using criteria proposed by the Surveillance of Cerebral Palsy in Europe (SCPE) network. MATERIAL All children in Norway with CP born in January 1996-December 1998 were registered in the Cerebral Palsy Registry of Norway. The Medical Birth Registry of Norway(More)
Infants with low birth weight are at increased risk of perinatal brain injury. Disruption of normal cortical development may have consequences for later motor, behavioural and cognitive development. The aim of this study was to measure cerebral cortical thickness, area and volume with an automated MRI technique in 15-year-old adolescents who had low birth(More)
BACKGROUND Preterm born children with very low birth weight (VLBW: bw ≤ 1500 g) have an increased risk of perinatal brain injury which may influence the subsequent maturation of grey and white matter. Aberrant cortical development may have implications for future cognitive functioning. AIMS The aim of this study was to measure deviations in cortical(More)
BACKGROUND The entorhinal cortex serves as an important gateway between the cerebral cortex and the hippocampus by receiving afferent information from limbic, modality sensory-specific, and multimodal association fibers from all the brain lobes. AIM To investigate whether thinning of entorhinal cortex is associated with reduced perceptual, cognitive and(More)
Preterm birth with very low birth weight (VLBW, ≤1500 g) is connected to reduced white matter (WM) integrity in childhood and adolescence. These changes in WM are correlated to motor, sensory and neuropsychological impairments. CNS myelination continues into the early twenties, but the consequences of this for WM integrity in VLBWs have not been explored.(More)
Being born with very low birth weight (VLBW, birth weight<or=1500 g) or small for gestational age (SGA) carries an increased risk of cerebral white matter damage. The reduced cognitive and motor skills these two groups exhibit suggest that the early injuries to white matter persist into adolescence. White matter integrity was assessed using voxel-wise(More)
BACKGROUND Hypoxia-ischemia (HI) induces delayed inflammation and long-term gray and white matter brain injury that may be altered by hyperoxia. METHODS HI and 2 h of hyperoxia (100% O2) or room air (21% O2) in 7-d-old (P7) rats were studied by magnetic resonance imaging at 7 Tesla during 42 d: apparent diffusion coefficient (ADC) maps on day 1;(More)
Hypoxic-ischemic injury (HI) to the neonatal brain results in delayed neuronal death with accompanying inflammation for days after the initial insult. The aim of this study was to depict delayed neuronal death after HI using Manganese-enhanced MRI (MEMRI) and to evaluate the specificity of MEMRI in detection of cells related to injury by comparison with(More)
INTRODUCTION Quantitative MRI measurements have revealed abnormalities in cortical development in children born preterm with very-low-birth-weight (VLBW). These children also have increased risk of cognitive deficits that persist into adulthood. The aim of this study was to investigate cortical surface area in VLBW young adults at age 19 compared with(More)
To explore associations between psychiatric symptoms and cerebral magnetic resonance imaging abnormalities in low-birth-weight adolescents, 55 very low-birth-weight (<or=1500 gm), 54 term small for gestational age (birth weight <10th centile) and 66 term control adolescents (birth weight >or=10th centile) were assessed at 14-15 years of age.
