Postconcussive Symptoms After Early Childhood Concussion.

Area of Science:

• Pediatric neurology
• Developmental psychology
• Traumatic brain injury research

Background:

• Research on postconcussive symptoms (PCS) in early childhood is limited by a lack of age-appropriate assessment tools.
• Understanding the evolution of PCS in young children is crucial for timely diagnosis and management.

Purpose of the Study:

• To document PCS in the first 3 months after early childhood concussion using a developmentally appropriate measure.
• To compare PCS in young children with concussion to those with orthopedic injuries and uninjured controls.

Main Methods:

• A prospective, multicenter, longitudinal cohort study involving children aged 6 to 72 months.
• Caregiver observations using the Report of Early Childhood Traumatic Injury Observations & Symptoms inventory assessed PCS at multiple time points.
• Ordinal regression models were used for group comparisons.

Main Results:

• Children with concussion showed significantly higher rates of PCS compared to orthopedic injury and control groups up to 3 months post-injury.
• Significant differences were observed in total PCS and domain-level scores (cognitive, physical, behavioral) at various assessment points.
• No significant differences in pre-injury PCS were found between the concussion and comparison groups.

Conclusions:

• Concussion in early childhood is associated with a higher burden of PCS compared to orthopedic injuries or typical development.
• The use of developmentally appropriate measures is valuable for tracking PCS and supporting concussion diagnosis in young children.
• Findings highlight the importance of specialized assessment tools for evaluating concussion outcomes in this vulnerable population.
