Insights

Very preterm children show deficits in spatial memory, impacting learning and memory abilities. Virtual reality tasks revealed impaired hippocampal function in these children compared to controls.

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Cognitive Psychology

Background:

  • Very preterm birth can impede nervous system development, particularly the vulnerable hippocampus.
  • The perinatal period is crucial for hippocampal growth, influencing learning and memory functions.
  • Spatial memory relies on the integrity of the hippocampus.

Purpose of the Study:

  • To assess spatial memory in very preterm children using virtual reality.
  • To compare the performance of very preterm children with a control group.

Main Methods:

  • Virtual reality-based tasks were employed to evaluate spatial memory.
  • Twenty very preterm children (7-8 years old) and a control group participated.
  • Two difficulty conditions were implemented in the tasks.

Main Results:

  • Very preterm children made more errors in locating rewarded positions than controls.
  • No significant differences in mean speed were found between groups, indicating preserved motor abilities.
  • Performance suggests an impact on hippocampal function in very preterm children.

Conclusions:

  • Spatial memory is affected in children born very preterm.
  • Virtual reality is a viable tool for assessing cognitive functions in this population.
  • Further research should explore other contributing variables to these deficits.
