Insights
Infant activity levels, not attention, may predict later ADHD traits. Early behavioral differences in activity may signal future attention-deficit/hyperactivity disorder (ADHD) risk in children.
Area of Science:
- Developmental neuroscience
- Child psychology
- Behavioral pediatrics
Background:
- Early identification of neurocognitive differences is crucial for timely interventions in attention-deficit/hyperactivity disorder (ADHD).
- Understanding infant precursors to ADHD can inform early risk assessment and support.
Purpose of the Study:
- To examine group differences in infant attention and activity levels based on family history of ADHD or Autism Spectrum Disorder (ASD).
- To investigate the longitudinal relationship between infant behavioral measures and preschool ADHD traits.
Main Methods:
- Assessed 151 infants at 10 months using multi-method approaches (behavioral, cognitive, physiological, neural) for attention and activity.
- Measured preschool ADHD traits at 3 years using the Child Behaviour Checklist (CBCL) and Child Behaviour Questionnaire (CBQ).
Main Results:
- No significant group differences in infant attention or activity were found between infants with and without a family history of ADHD or ASD.
- Infant activity level, as rated by parents and observers, positively correlated with preschool ADHD traits at 3 years.
Conclusions:
- Observable differences in infant activity levels, but not attention, may be early indicators for later ADHD traits.
- While group differences were not significant at 10 months, individual infant activity levels show predictive value for later ADHD symptomatology.
Abstract:
Mapping infant neurocognitive differences that precede later ADHD-related behaviours is critical for designing early interventions. In this study, we investigated (1) group differences in a battery of measures assessing aspects of attention and activity level in infants with and without a family history of ADHD or related conditions (ASD), and (2) longitudinal associations between the infant measures and preschool ADHD traits at 3 years. Participants (N = 151) were infants with or without an elevated likelihood for ADHD (due to a family history of ADHD and/or ASD). A multi-method assessment protocol was used to assess infant attention and activity level at 10 months of age that included behavioural, cognitive, physiological and neural measures. Preschool ADHD traits were measured at 3 years of age using the Child Behaviour Checklist (CBCL) and the Child Behaviour Questionnaire (CBQ). Across a broad range of measures, we found no significant group differences in attention or activity level at 10 months between infants with and without a family history of ADHD or ASD. However, parent and observer ratings of infant activity level at 10 months were positively associated with later preschool ADHD traits at 3 years. Observable behavioural differences in activity level (but not attention) may be apparent from infancy in children who later develop elevated preschool ADHD traits.
