Neurobehavioral outcome after closed head injury in childhood and adolescence
Insights
Long-term outcomes for children with closed head injuries depend on injury severity and coma duration. Diffuse injuries with focal lesions and prolonged coma (over one month) indicate poorer prognoses and potential emotional disturbances.
Area of Science:
- Pediatric Neurology
- Neurotraumatology
- Clinical Neuroscience
Background:
- Closed head injuries in children and adolescents can lead to significant long-term deficits.
- Understanding the clinicopathological factors influencing outcome is crucial for effective management.
- Previous research highlights the impact of injury severity on recovery trajectories.
Purpose of the Study:
- To investigate the long-term outcomes of pediatric patients with closed head injuries.
- To correlate clinicopathological findings and coma duration with functional recovery.
- To identify factors associated with emotional and behavioral disturbances post-injury.
Main Methods:
- Retrospective review of hospital records for 53 pediatric patients (≤18 years) with closed head injury.
- Classification of patients into clinicopathologic groups using computed tomographic scans.
- Assessment of outcomes via the Glasgow Outcome Scale, social behavior, school performance, and vocational functioning.
Main Results:
- Patients with diffuse injury and focal lesions exhibited worse outcomes compared to those with diffuse injury alone.
- Coma duration exceeding one month was a significant predictor of poorer long-term outcomes in both injury groups.
- A substantial proportion of individuals experienced limiting emotional disturbances, potentially linked to frontal lobe system disruption.
Conclusions:
- Injury complexity (diffuse plus focal lesions) and prolonged coma are critical determinants of poor outcomes in pediatric closed head injury.
- Disruption of frontal systems may underlie the observed emotional and behavioral sequelae.
- Long-term follow-up focusing on neurological and psychosocial functioning is essential for this patient population.
Abstract:
Hospital records of 53 children and adolescents, aged 18 years or less, with closed head injury were reviewed for information on long-term outcome. Computed tomographic scans were used to divide the patients into clinicopathologic groups. Within these groups, duration of coma was the major index of severity. Outcome was assessed using the Glasgow Outcome Scale and by evaluating social behavior, school performance, and vocational functioning. Patients with diffuse injury plus focal lesions fared worse than those with diffuse injury only. Coma lasting more than one month led to a poorer outcome in both groups. Many individuals had limiting emotional disturbances, which may have resulted from disruption of frontal systems modulating arousal and social behavior.
