Headache after pediatric traumatic brain injury: a cohort study

Area of Science:

• Pediatric Neurology
• Neurotraumatology
• Epidemiology

Background:

• Headache is a common sequela following pediatric traumatic brain injury (TBI).
• Understanding the temporal patterns and risk factors for post-TBI headache is crucial for effective management.
• Previous studies have varied in their assessment of headache prevalence and associated factors after pediatric TBI.

Purpose of the Study:

• To investigate the prevalence of headache at 3 and 12 months following pediatric traumatic brain injury (TBI).
• To compare headache prevalence in children with mild TBI (mTBI) and moderate/severe TBI against a control group with arm injury (AI).
• To identify demographic and injury-related factors associated with headache development and persistence.

Main Methods:

• Prospective cohort study involving children aged 5-17 years.
• Participants included children with mild TBI (n=402), moderate/severe TBI (n=60), and controls with arm injury (n=122).
• Headache prevalence was assessed at 3 and 12 months post-injury using standardized methods.

Main Results:

• Headache prevalence at 3 months was significantly higher in mTBI (43%) and moderate/severe TBI (60%) groups compared to controls (26%).
• Adolescents and girls showed a higher risk of headache at 3 months post-TBI.
• While headache frequency decreased by 12 months, girls with mTBI reported more frequent serious headaches.

Conclusions:

• Pediatric TBI is a significant risk factor for developing headaches in the months following injury.
• Headache prevalence is influenced by injury severity, time elapsed since injury, age, and gender.
• Girls and adolescents are identified as high-risk groups for experiencing headaches after TBI.
