Insights
Preterm birth impacts executive functions (EF). Cool EF deficits persist, while hot EF shows catch-up growth in preterm children during early adolescence, highlighting complex cognitive development needs.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Preterm birth is a significant risk factor for cognitive developmental challenges.
- Executive functions (EF), crucial for cognitive control, are particularly vulnerable to effects of preterm birth.
- Understanding distinct trajectories of hot (emotionally-laden) and cool (neutral) EF is vital for preterm populations.
Purpose of the Study:
- To investigate the longitudinal trajectories of hot and cool executive functions (EF) in preterm versus full-term children.
- To examine brain-behavior relationships associated with EF development in preterm individuals.
- To identify potential differences in cognitive-brain maturation interactions in preterm children.
Main Methods:
- Utilized data from 3508 children (aged 9-10 at baseline) from the Adolescent Brain and Cognitive Development (ABCD®) study, with longitudinal follow-up over 4 years.
- Employed linear mixed models to analyze EF task performance and MRI data, assessing differences between preterm and full-term groups.
- Applied bivariate latent change score analyses to explore bidirectional brain-behavior relationships.
Main Results:
- Preterm children exhibited persistent deficits in cool EF tasks throughout the study period.
- A notable catch-up pattern was observed for hot EF performance in preterm children during early adolescence.
- Brain-behavior analyses revealed distinct, altered bidirectional relationships in specific brain regions for preterm individuals, indicating modified cognitive-brain maturation.
Conclusions:
- Preterm birth has differential impacts on hot and cool executive functions, with cool EF deficits persisting and hot EF showing recovery.
- Altered brain-behavior interactions suggest unique developmental pathways in preterm children.
- Findings underscore the necessity for tailored, long-term interventions and monitoring for preterm-born individuals to address specific EF challenges.
Abstract:
Preterm birth can significantly impact cognitive development, particularly executive functions (EF). This study investigated hot (with emotional/motivational aspects) and cool (purely neutral/cognitive) EF trajectories in preterm and full-term children, examining brain-behavior relationships. It included 3508 participants aged 9-10 years (mean age 10.0 years) at baseline from the Adolescent Brain and Cognitive Development (ABCD®) study, evenly split between preterm and full-term births (54.36 % males; 1.05 % Asian American, 10.69 % Black, 15.68 % Hispanic, 61.57 % White, 11.09 % other). Participants were followed for 4 years, completing MRI scans and a cool EF task at baseline and at the 2-year follow-up, as well as hot/cool and hot EF tasks at the 1- and 3-year follow-ups. Linear mixed models showed varying effects of preterm birth across the different EF tasks. Specifically, preterm children showed persistent cool EF deficits and a catch-up pattern for hot EF, while performance on the hot/cool task showed no association with preterm birth. Brain-behavior bivariate latent change score analyses identified distinct bidirectional relationships in specific regions, suggesting altered cognitive-brain maturation interactions in preterm children. These findings highlight the complex nature of EF development following preterm birth: while cool EF deficits persist, hot EF shows catch-up growth in preterm children during early adolescence. This emphasizes the need for tailored interventions and long-term follow-up in this population.
