Executive functioning in the first year after pediatric traumatic brain injury

Area of Science:

• Neuroscience
• Pediatrics
• Psychology

Background:

• Traumatic brain injuries (TBIs) in children frequently lead to impaired executive function, affecting goal-directed behavior.
• The Behavior Rating Inventory of Executive Function (BRIEF) is a caregiver-report tool assessing executive function in daily life.

Purpose of the Study:

• To document executive function changes in children during the first year after TBI.
• To identify child, family, and injury-related factors associated with executive dysfunction post-TBI.
• To compare executive function in children with TBI versus orthopedic fractures.

Main Methods:

• A longitudinal study involving 330 children (aged 5-15) with mild-to-severe TBI and 103 orthopedic fracture controls.
• Caregivers completed the BRIEF via telephone at baseline (retrospective), 3 months, and 1 year post-injury.

Main Results:

• Children with TBI showed significantly more executive dysfunction than controls by 3 months and 1 year post-injury.
• The working memory scale was the only measure differentiating TBI severity groups at 3 and 12 months.
• Preexisting learning/behavior problems, lower parental education, and poor family functioning predicted greater executive dysfunction.

Conclusions:

• 18-38% of children with TBI experienced significant executive dysfunction in the first year, with severity linked to TBI severity.
• Preinjury factors like learning problems and family issues negatively impact executive function.
• Systematic screening for executive dysfunction post-TBI is crucial for timely intervention and support.
