Abstract

Background Preterm born children with very low birth weight (VLBW: bw ≤ 1500 g) have an increased risk of perinatal brain injury which may influence the subsequent maturation of grey and white matter. Aberrant cortical development may have implications for future cognitive functioning.Aims The aim of this study was to measure deviations in cortical thickness and to investigate the relationship between cortical thickness, perinatal variables and IQ measurements in VLBW late teenagers compared with term-born controls.Study design Prospective follow-up study of three year cohorts of children from birth to early adulthood.Subject Forty-seven VLBW and 61 term born controls were examined at ages 18-21.Outcome measures Cognitive function was assessed with the WAIS-III, measuring full IQ and IQ indices. We applied an automated method to reconstruct the cortical surface based on T1-weighted MRI images using the FreeSurfer software.Results We found widespread areas of thinner cerebral cortex in the left parietal and temporal lobes and thicker cortex in frontal areas bilaterally in the VLBW group compared to controls. There were positive correlations between IQ and cortical thickness in areas in ventro-lateral frontal, parietal and temporal lobes in the VLBW group. The most pronounced cortical changes were seen in the VLBW subjects with the lowest birth weight and gestational age, and in those with IQ below 89.Conclusion Persistent cortical deviations seen in VLBW late teenagers are associated with immaturity at birth and level of cognitive functioning.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
