Insights
Children with traumatic brain injury (TBI) may experience persistent attentional deficits up to 10 years post-injury, especially after severe TBI. Early intervention is crucial for managing these cognitive challenges.
Area of Science:
- Pediatric neurology
- Neuropsychology
- Developmental psychology
Background:
- Traumatic brain injury (TBI) in early childhood can impact long-term cognitive development.
- Attentional deficits are a common consequence of TBI, but their persistence over a decade is not well-documented.
Purpose of the Study:
- To investigate attentional deficits 10 years after pediatric traumatic brain injury (TBI).
- To determine if TBI severity predicts long-term attentional impairments.
- To identify factors influencing attention 10 years post-TBI.
Main Methods:
- Prospective cohort study of 40 children with mild to severe TBI (ages 1-7 years) and 19 non-injured controls.
- Assessment of attentional abilities 10 years after the initial TBI.
- Analysis of environmental predictors, age at injury, and acute IQ as potential factors.
Main Results:
- Attentional deficits persisted up to 10 years post-TBI, particularly following severe injuries.
- Both early- and later-developing attention skills were compromised.
- Age at injury and acute IQ were significant predictors of attention at 10 years, while environmental factors were not.
Conclusions:
- Serious TBI in preschool-aged children can lead to lasting attentional deficits.
- Clinicians should screen for and intervene in attentional difficulties to mitigate long-term consequences.
Objective:
To date no study has reported findings regarding attentional deficits following pre-school paediatric traumatic brain injury (TBI), as long as 10 years post-injury. It was predicted that more severe TBI would be associated with generalized deficits at 10 years post-TBI, particularly for skills not mastered at time of injury.
Research Design:
The sample comprised 40 prospectively-recruited children (42% of the original sample) who had sustained a mild, moderate or severe traumatic brain injury (TBI) between the ages of 1-7 years and 19 non-injured control participants. Children were assessed 10 years post-TBI, with a focus on measures of attentional ability.
Outcomes/Results:
While attentional deficits were not evident across all components of attentional ability, both early- and later-established attention skills were compromised, particularly following severe TBI. Environmental predictors were generally not successful predictors of attentional outcome at 10 years post-TBI. Age at injury and acute IQ were identified as contributing to attention at 10 years.
Conclusions/Implications:
The present study shows that attentional deficits do occur and persist to 10 years following serious TBI. Clinicians may be able to screen for such deficits and so intervene in order to prevent or lessen the consequences of such difficulties.
