Three-Month Psychiatric Outcome of Pediatric Mild Traumatic Brain Injury: A Controlled Study

Area of Science:

• Pediatric Psychiatry
• Neuropsychology
• Traumatology

Background:

• Mild traumatic brain injury (mTBI) and orthopedic injuries (OI) are common in children.
• The psychiatric sequelae of mTBI in pediatric populations require further elucidation.
• Understanding risk factors for novel psychiatric disorders (NPD) post-injury is crucial for timely intervention.

Purpose of the Study:

• To determine the incidence, characteristics, and risk factors for NPD in children within 3 months of mTBI versus OI.
• To compare the psychiatric outcomes between children with mTBI and those with OI.

Main Methods:

• Prospective cohort study of 330 children (8-15 years) admitted to an emergency department.
• Participants included 220 with mTBI and 110 with OI (no TBI).
• Semi-structured psychiatric interviews were conducted at baseline and 3 months post-injury to assess NPD. Pre-injury child and family variables were analyzed as potential predictors.

Main Results:

• NPD occurred significantly more frequently in children with mTBI compared to OI, even after adjusting for confounders (MR=3.724, p=0.015).
• Independent predictors of higher NPD frequency included pre-injury psychiatric disorder (MR=2.284, p=0.043), high family psychiatric history (MR=2.748, p=0.016), and worse socioeconomic status (MR=0.618, p=0.037).

Conclusions:

• Mild traumatic brain injury has a significantly greater negative impact on pediatric psychiatric outcomes in the initial 3 months post-injury compared to orthopedic injury.
• Child and family variables independently contribute to adverse psychiatric outcomes, highlighting the need for comprehensive assessment and support.
