Insights
Amplitude-integrated electroencephalography (aEEG) alterations in preterm infants are linked to poorer literacy precursor skills by age five. This suggests aEEG can help identify preterm infants at risk for developmental issues.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
- Neuroscience
Background:
- Preterm birth is associated with increased risk of neurodevelopmental complications.
- Early identification of developmental risks in preterm infants is crucial for timely intervention.
- Amplitude-integrated electroencephalography (aEEG) is a non-invasive tool used to monitor brain activity in neonates.
Purpose of the Study:
- To investigate the association between neonatal aEEG patterns and literacy precursor skills at five years of age in preterm-born children.
- To determine if aEEG can serve as an early indicator of potential reading and spelling difficulties.
Main Methods:
- A cohort of 248 preterm infants underwent aEEG analysis, examining background activity, continuous activity percentage, and amplitude measures.
- At five years of age, children were assessed using the Bielefelder screening (BISC) to evaluate early literacy skills, categorizing them into normal and poor performers.
- Statistical comparisons were made between the groups based on aEEG parameters at two and three weeks postnatal.
Main Results:
- Infants who later demonstrated poor BISC performance had significantly lower minimum aEEG amplitude at two weeks postnatal.
- A higher percentage of continuous background activity on aEEG at three weeks postnatal was observed in infants with normal BISC performance.
- These findings indicate distinct aEEG signal alterations correlating with later literacy outcomes.
Conclusions:
- Alterations in neonatal aEEG signals are associated with the development of poor literacy precursor skills in preterm-born children.
- aEEG monitoring in the newborn period may aid in identifying preterm infants at higher risk for developmental complications, including those affecting literacy.
- This research highlights the potential of aEEG as a valuable tool for early neurodevelopmental risk assessment in preterm populations.
Aim:
To assess whether amplitude-integrated electroencephalography (aEEG) alterations in the newborn period are associated with poor precursor skills of literacy at five years of age in children born preterm.
Methods:
Between October 2007 and September 2011 248 preterm infants were eligible for the study at Innsbruck Medical University Hospital. aEEG was analysed for dominating background activity, calculation of the percentage of continuous activity, the Burdjalov scoring system, the minimum, mean and maximum amplitude. At the age of five years, we evaluated preterm born children by the Bielefelder screening (BISC) to assess for early diagnosis of reading problems and weak spelling and classified them as normal performers (n = 64) or poor performers (n = 20). Completion of testing was not possible for one infant.
Results:
The minimum amplitude was significantly lower in the poor BISC performance group as compared to the normal BISC performance group at postnatal week two. The percentage of continuous background activity was significantly higher in infants with normal BISC performance than in infants with poor BISC performance at postnatal week three.
Conclusion:
Children with poor developed precursor skills of literacy showed alterations in aEEG signals. The aEEG could be useful in further diagnosing preterm infants at risk for developmental complications.
