[Long-term cognitive dysfunctions in preterm subjects with intraventricular haemorrhage].

Introduction: Intraventricular hemorrhage (IVH) in the neonatal period has been associated to developmental impairment or delay in preterm born children and adolescents. To our knowledge there is no study in literature which describes the effects of neonatal IVH in preterm subjects on different specific cognitive functions in adolescent samples. AIM.

[Long-term cognitive dysfunctions related to prematurity].

Introduction: Little is understood about the effects of prematurity on long-term cognitive functioning. No detailed studies have been carried out in a Spanish population to investigate the cognitive performance of adolescents who were born preterm.

Aims: To utilise the Wechsler intelligence scales to examine the performance of a broad sample of adolescents who were born preterm, to describe the clinical significance of this performance and to analyse the discriminatory powers of the different subtests.

[A neuropsychological study of triplets with a history of prematurity].

Introduction And Aims: Prematurity has often been associated with a general intellectual deficit and with different structural brain disorders which can be revealed by volumetric measurements performed by magnetic resonance imaging (MRI). In turn, perinatal asphyxia, even when it is not accompanied by neurological disorders, is related to a deficit in specific neuropsychological functions.

Case Report: This study describes the case of three 13 year old female triplets, with a history of extreme prematurity and perinatal asphyxia, the long term effects of which are evaluated in terms of cognitive performance.

[Evaluation of diffuse cerebral atrophy in patients with a history of traumatic brain injury and its relation to cognitive deterioration].

Introduction: Diffuse damage secondary to traumatic brain injury (TBI) can be studied through volumetric analysis of several structures that are sensible to this kind of injury, such as corpus callosum, ventricular system, hippocampus, basal ganglia and the volume of cerebrospinal fluid spaces.

Objective: Our aim is to describe how closed head injury (CHI) occurred in early years produce diffuse damage, and how this damage affects general cognitive functioning at long term.

Patients And Methods: Initially the group of subjects was composed of 27 head injured children and adolescents following paediatric moderate to severe TBI.
