Genetic and epigenetic factors and early life inflammation as predictors of neurodevelopmental outcomes

Area of Science:

• Neuroscience
• Developmental Pediatrics
• Neonatology

Background:

• Perinatal inflammation is a significant risk factor for adverse neurodevelopmental outcomes in very preterm infants.
• Associated factors include socioeconomic disadvantage, maternal health issues, fetal growth restriction, and neonatal complications.
• Genetic predisposition and epigenetic modifications may influence susceptibility and outcomes.

Purpose of the Study:

• To explore the link between perinatal inflammation and neurodevelopmental impairments in very preterm infants.
• To identify antecedents, correlates, and modifying factors of this relationship.
• To highlight the need for interventions to mitigate inflammation and improve neurodevelopmental trajectories.

Main Methods:

• Review of existing literature on perinatal inflammation and neurodevelopmental outcomes.
• Analysis of factors contributing to and associated with perinatal inflammation.
• Exploration of genetic and epigenetic influences.
• Consideration of potential moderators like sex and environmental exposures.

Main Results:

• Sustained or recurring perinatal inflammation strongly correlates with conditions such as cerebral white matter damage, cerebral palsy, cognitive impairment, attention-deficit/hyperactivity disorder, and autism spectrum disorder.
• Multiple factors, including maternal conditions and neonatal complications, contribute to perinatal inflammation.
• Preliminary evidence suggests epigenetic markers may mediate the effects of inflammation on neurodevelopment.

Conclusions:

• Perinatal inflammation is a critical factor impacting neurodevelopment in very preterm infants.
• Further research is required to understand modifying factors and develop effective interventions.
• Targeting inflammation holds promise for improving long-term neurodevelopmental outcomes.
