  1. 1. Caspase-dependent and caspase-independent neuronal injury in the developing brain

    Författare :Changlian Zhu; Göteborgs universitet; []
    Nyckelord :hypoxia ischemia; neonatal; cell death; caspase; apoptosis-inducing factor; brain; apoptosis; autophagy; nitric oxide;

    Sammanfattning : Aims: To investigate the mechanisms of neuronal cell death after hypoxia-ischemia in the developing brain.Methods: Rats or mice were subjected to left common carotid artery ligation plus hypoxia. Animals were sacrificed at certain time points after hypoxia-ischemia. LÄS MER

  3. 2. Brain maturation, cognitive tasks, and quantitative electroencephalography : a study in children with attention deficit hyperactive disorder

    Författare :Eman Mohamed El-Sayed; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ADHD; twin study; twin design; case control study; maturation; developmental trajectories; maturational lag hypothesis; brain immaturity; QEEG; Vigilance Task; Delay Task;

    Sammanfattning : Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common psychiatric disorders of childhood. Despite a long history, widespread clinical acceptance, and extensive research, the diagnosis and treatment are still controversial. LÄS MER

  4. 3. Diffusion magnetic resonance imaging for investigating alterations in brain organization after injury during early development : with specific reference to the motor and visual system

    Författare :Finn Lennartsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Disturbances or injuries to the brain during early development cause different types of structural abnormalities, depending mainly on the stage of maturation of the brain at the time of the insult. These are, herein, collectively referred to as early brain lesions. LÄS MER

  5. 4. Auditory event-related potentials and cognitive outcome after very preterm birth

    Författare :Holger Hövel; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm; Event-related potentials; Mismatch negativity; Magnetic resonance imaging; developmental outcome;

    Sammanfattning : Children born before 32 gestational weeks have a high incidence of neuropsychological deficits. The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. LÄS MER

  7. 5. Visual function in very low birth weight adolescents : fifteen-year follow-up of children in southeast Sweden

    Författare :Kerstin Hellgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Very low birth weight (VLBW < 1500 g) carries an increased risk of visual and cognitive deficits. Long term follow-up studies are sparse. The associations between neural structure and visual and cognitive outcome need to be more fully explored. LÄS MER
