Insights
Neurodevelopment after preterm birth is highly variable, with unique brain abnormality patterns in individuals. These patterns share common biological mechanisms and are influenced by early social environments, suggesting targeted interventions.
Area of Science:
- Neuroscience
- Developmental Biology
- Medical Imaging
Background:
- Preterm birth leads to diverse neurocognitive outcomes, contrasting with imaging studies suggesting uniform brain aberrations.
- Existing research often overlooks individual variations in neurodevelopmental trajectories post-preterm birth.
Purpose of the Study:
- To investigate the heterogeneity and consistency of brain abnormalities in preterm infants, children, and adults.
- To identify underlying biological mechanisms and environmental influences on neurodevelopment after preterm birth.
Main Methods:
- Utilized cross-sectional structural magnetic resonance imaging (MRI) data from preterm neonates.
- Employed longitudinal MRI data from preterm children and adults within a normative reference framework.
- Analyzed spatial patterns of brain abnormality, glial cell underpinnings, and social environmental influences.
Main Results:
- Demonstrated highly heterogeneous patterns and severity of brain deviations in individuals born preterm.
- Identified consistent individual brain abnormality patterns in extent and location across the life course.
- Found associations between brain abnormalities, glial cell biology, and early social environment plasticity.
Conclusions:
- Preterm neurodevelopment exhibits significant individual variation in brain abnormality patterns and severity.
- Consistent biological mechanisms and environmental plasticity shape these individual trajectories.
- Recommends integrated theranostic strategies, including early brain imaging and social interventions, for targeted support.
Abstract:
The current view of neurodevelopment after preterm birth presents a strong paradox: diverse neurocognitive outcomes suggest heterogeneous neurodevelopment, yet numerous brain imaging studies focusing on average dysmaturation imply largely uniform aberrations across individuals. Here we show both, spatially heterogeneous individual brain abnormality patterns but with consistent underlying biological mechanisms of injury and plasticity. Using cross-sectional structural magnetic resonance imaging data from preterm neonates and longitudinal data from preterm children and adults in a normative reference framework, we demonstrate that brain development after preterm birth is highly heterogeneous in both severity and patterns of deviations. Individual brain abnormality patterns are also consistent for their extent and location along the life course, associated with glial cell underpinnings, and plastic for influences of the early social environment. Our findings extend conventional views of preterm neurodevelopment, revealing a nuanced landscape of individual variation, with consistent commonalities between subjects. This integrated perspective implies more targeted theranostic intervention strategies, specifically integrating brain charts and imaging at birth, as well as social interventions during early development.
