Summary

Mild head injuries in children can cause temporary brain disorders, often linked to pre-existing conditions like perinatal issues or migraines. These benign posttraumatic encephalopathy cases typically resolve fully.

Area of Science:

  • Pediatric Neurology
  • Neurotraumatology

Background:

  • Benign posttraumatic encephalopathy (BPTE) is a transient brain disorder following mild head injury in children.
  • Pre-existing neurological conditions may influence the development and presentation of BPTE.

Purpose of the Study:

  • To characterize the clinical features and outcomes of BPTE in children.
  • To investigate potential predisposing factors for BPTE.

Main Methods:

  • Retrospective assessment of 28 post-injury states in 27 children (aged 1-9 years) following mild head trauma.
  • Clinical evaluation, EEG analysis, and review of medical history, including perinatal and neurological status.

Main Results:

  • Transient brain disorders, including altered consciousness, cortical blindness, seizures, and brainstem disturbances, occurred after a latent period.
  • Symptoms resolved within 48 hours with no long-term sequelae; mean follow-up was 3.3 years.
  • Perinatal abnormalities and minimal brain dysfunction (57%) were common, followed by migraine (16%).

Conclusions:

  • BPTE in children is characterized by transient neurological deficits after mild head injury.
  • Pre-existing cerebral affections, such as perinatal issues and minimal brain dysfunction, appear to play a significant role in the pathogenesis of BPTE.
