Infants born very preterm have an increased risk of brain injury. Given the great increase in the number of such infants that are surviving, it is important to establish whether any resultant brain abnormalities persist into adolescence and adult life. We therefore examined in vivo whole brain, grey matter, white matter and hippocampal volumes, ventricular(More)
Very preterm (VPT) birth is associated with altered cortical development and long-term neurodevelopmental sequelae. We used voxel-based morphometry to investigate white (WM) and grey matter (GM) distribution in VPT adolescents and controls, and the association with gestational age and neonatal ultrasound findings in the VPT individuals. GM and WM volumes(More)
Thinning of the corpus callosum (CC) is often observed in individuals who were born very preterm. Damage to the CC during neurodevelopment may be associated with poor neuropsychological performance. This study aimed to explore any evidence of CC pathology in adolescents aged 14-15 years who were born very preterm, and to investigate the relationship between(More)
OBJECTIVE To examine the growth of the corpus callosum between adolescence and early adulthood in individuals who were born before 33 weeks' gestation (very preterm [VPT]) and its relation to neuropsychological function. DESIGN A longitudinal cohort study of VPT individuals born between January 4, 1982, and December 29, 1984, and a term-born comparison(More)
Individuals born very preterm (VPT) are at increased risk of perinatal brain injury and long-term cognitive and behavioral problems. Executive functioning, in particular, has been shown to be impaired in VPT children and adolescents. This study prospectively assessed executive function in young adults who were born VPT (<33 weeks of gestation) [n = 61; mean(More)
Children and adolescents born before 33 weeks of gestation, that is very preterm, may experience problems with the inhibitory control of behaviour and the allocation of attention. Previous functional magnetic resonance imaging (fMRI) studies have found preterm-born adolescents to display altered brain activation in tasks measuring inhibitory control.(More)
Event-related functional magnetic resonance imaging (fMRI) was used to investigate the hypothesis that males who were born very preterm may show differences in relative strength of blood oxygen level dependent (BOLD) signals in selective brain areas during performance of a simple response inhibition task compared with term-born controls. Participants were(More)
INTRODUCTION Very preterm birth (VPT; <33 weeks' gestation) is associated with later neuromotor and cognitive impairment, reduced school performance, and psychiatric morbidity. Several follow-up studies have demonstrated increased anxiety and social rejection and reduced self-esteem in preterm children and adolescents, but few studies have examined the(More)
Adolescence is a time of social and cognitive development associated with changes in brain structure and function. These developmental changes may show an altered path in individuals born before 33 weeks' gestation (very preterm; VPT). The cerebellum is affected by VPT birth, but no studies have yet assessed the adolescent development of this structure, or(More)
Very-low-birthweight (VLBW) individuals are at high risk of brain injury in the perinatal period. We wished to determine how such early brain lesions affect brain structure in adulthood. Thirty-two VLBW adults (20 female, 12 male) and 18 term, normal birthweight sibling control individuals (nine female, nine male) underwent structural MRI at a mean age of(More)
