Insights

White matter (WM) in preterm children shows gradual maturation over the first two years. Full-term infants achieve WM maturation earlier, highlighting the need for early intervention in preterm infants.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Pediatric Radiology

Background:

  • Preterm birth is associated with widespread white matter (WM) pathology.
  • Understanding WM development in preterm infants is crucial for early diagnosis and intervention.

Purpose of the Study:

  • To investigate maturational differences in white matter (WM) between preterm infants and full-term infants.
  • To compare WM development in preterm infants with thinning of the corpus callosum to that of full-term infants.

Main Methods:

  • Diffusion tensor imaging (DTI) was used to assess white matter (WM) in 18 preterm and 18 full-term children.
  • Tract-based spatial statistics (TBSS) analyzed fractional anisotropy (FA) differences across age-related subgroups.
  • Children were grouped by corrected age at the time of DTI scanning.

Main Results:

  • White matter (WM) fractional anisotropy (FA) values increased with age in preterm children, indicating gradual maturation over the first two years.
  • Full-term infants reached WM maturation by approximately one year of age.
  • The centrum semiovale region showed sustained maturation in full-term infants throughout the first two years.

Conclusions:

  • Significant radiologic maturational differences exist in white matter (WM) between preterm and full-term children.
  • Therapeutic interventions within the first two years of birth are essential for preterm infants.
  • Early intervention can prevent specific functional impairments and improve clinical outcomes in preterm children.
