Introduction: There is a large body of evidence to suggest that the GH axis plays an important role in brain myelination. However, results from studies in humans with an abnormal GH axis have varied and therefore there remains no consensus as to whether the GH/IGF1 axis plays a significant role in neural development. No previous studies have used diffusion tensor imaging (DTI) a sensitive magnetic resonance imaging (MRI) technique for studying brain white matter tracts, to add...

Background: GH deficiency is associated with reduction in IQ and neural volumes (globus pallidum and thalamus). Significant relationships between IGF1, IGFBP3 and brain volumes have also been described in children born extremely preterm (total brain volume and cerebellum). No published studies report the relationship between markers of GH status and brain volumes in healthy children.Methods: Cognitive assessment, MRI brain and measurement of IGF1 and IGF...
