Insights
Early antibiotic exposure in infants is linked to attention problems and altered brain activity (EEG). A Family Nurture Intervention may protect against these neurodevelopmental effects.
Area of Science:
- Neuroscience
- Developmental Pediatrics
- Microbiology
Background:
- Early antibiotic exposure is a risk factor for neurodevelopmental issues, including attention deficits.
- Electroencephalography (EEG) is a key biomarker for neurophysiological deficits.
- Preterm infants are vulnerable to attention deficits and often receive antibiotics.
Purpose of the Study:
- To investigate the impact of perinatal antibiotic exposure on neonatal EEG and attention deficits in children up to age 5.
- To evaluate the potential buffering effect of Family Nurture Intervention (FNI) against adverse neurodevelopmental outcomes.
Main Methods:
- Analysis of data from a randomized controlled trial comparing FNI to standard care in NICU infants.
- Assessment of attention deficits using the Child Behavior Checklist.
- Measurement of neonatal EEG power.
Main Results:
- Antibiotic-exposed infants exhibited increased attention problems.
- A significant main effect of antibiotic exposure showed higher EEG power in exposed infants.
- The adverse EEG effect was four times greater in infants receiving standard care versus FNI.
Conclusions:
- Perinatal antibiotic exposure is associated with altered neurodevelopment, including attention deficits and changes in EEG.
- Family Nurture Intervention may mitigate the negative neurodevelopmental consequences of antibiotic exposure in infants.
- Antibiotic-induced microbiome alterations are a potential mechanism for these neurodevelopmental effects.
Abstract:
Early exposure to antibiotics has been shown to increase risk for poor neurobehavioral development, particularly with regard to attention deficit disorders. Clinically, electroencephalography (EEG) is increasingly used as a biomarker of these deficits. Less is known about the effects of antibiotics on neurobehavioral and neurophysiological outcomes in preterm infants, a population at particularly high risk for attention deficits and perinatal antibiotic exposure. This study examines the effects of perinatal antibiotic exposure on neonatal EEG and attention deficits as measured by the Child Behavior Checklist in 4- to 5-year-old children who were enrolled in an NICU-based randomized controlled trial comparing Family Nurture Intervention (FNI) to standard care. Antibiotic-exposed infants had increased attention problems and there was a main effect of antibiotic exposure such that exposed infants had higher EEG power. This effect was fourfold greater in infants who received standard NICU care compared to those who received the intervention, suggesting a buffering effect of the intervention. We hypothesize that the relationship between antibiotic exposure and altered neurodevelopment may be due to effects of antibiotics on the microbiome, and that FNI may buffer these adverse consequences.
