Very low birth weight (VLBW) children are at high risk of perinatal white matter injury, which, when subtle, may not be seen using conventional magnetic resonance imaging. The relationship between clinical findings and fractional anisotropy (FA) measurements in white matter of adolescents born prematurely with VLBW was studied in 34 subjects (age = 15(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)
OBJECTIVE To determine whether preterm very low birth weight (VLBW) or term born small for gestational age (SGA) adolescents have reduced regional brain volumes. We also asked which perinatal factors are related to reduced brain volume in VLBW adolescents, which regional brain volumes are associated with cognitive and perceptual functioning, and if these(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 AND PURPOSE The intracranial volume is commonly used for correcting regional brain volume measurements for variations in head size. Accurate intracranial volume measurements are important because errors will be propagated to the corrected regional brain volume measurements, possibly leading to biased data or decreased power. Our aims were to(More)
The aim of this study was to investigate any structural-functional relationship between changes in white matter microstructure seen on diffusion tensor imaging and results of an executive function test in adolescents with very low birth weight (VLBW). Thirty-four VLBW adolescents were examined at 15 years of age. Executive function was assessed by the(More)
BACKGROUND . Motor learning mechanisms may be operative in stroke recovery and possibly reinforced by rehabilitative training. OBJECTIVES . To assess early motor network changes after acute ischemic stroke in patients treated with very early mobilization and task-oriented physical therapy in a comprehensive stroke unit, to investigate the association(More)
Premature birth is associated with visual impairments, due to both cerebral and ocular pathology. This study examined the relationship between cerebral white matter microstructure, evaluated by diffusion tensor imaging (DTI), and visual function, in 30 preterm born adolescents with very low birth weight (VLBW=birth weight⩽1500g) and an age-matched group of(More)
AIM To describe cognitive functioning with neuropsychological tests and examine predictors of cognitive outcome in adult survivors of out-of-hospital cardiac arrest (OHCA) of cardiac cause. METHOD The study was prospective and took place at the University hospital of North-Norway. Only patients eligible of neuropsychological assessment three months after(More)
PURPOSE To assess magnitude and duration of changes in myocardial longitudinal relaxation rate (R1) in humans following infusion of the manganese (Mn) releasing contrast agent MnDPDP (Mn-dipyridoxyl-diphosphate). MATERIALS AND METHODS Fifteen healthy volunteers were divided into three groups. After initial myocardial and liver R1 measurements using an(More)
