Reduction of the event-related potential P3 in preterm born 5-year-old healthy children

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Preterm birth can impact intrauterine brain development, increasing risks for later attention deficits.
• Existing research on attention deficits in preterm children is often symptom-based or uses neuropsychological tasks, with limited neurophysiological investigation.

Purpose of the Study:

• To investigate electrophysiological attention functioning in low-risk preterm children compared to term-born children.
• To explore potential subclinical attentional changes not evident in behavioral assessments.

Main Methods:

• Utilized electroencephalography (EEG) during an oddball task to assess attention in 27 preterm and 20 term children aged 5-6 years.
• Compared neurophysiological responses, specifically the oddball P3 component, between the two groups.

Main Results:

• Preterm children did not exhibit attention deficits on a symptom level.
• However, preterm children showed a blunted oddball P3 response compared to term children, indicating electrophysiological differences.

Conclusions:

• Results suggest subclinical attentional alterations in preterm children at the neurophysiological level, despite normal performance on behavioral tests.
• Emphasizes the need for early, closer monitoring of preterm children in preschool, even in the absence of overt clinical symptoms.
