Summary

Childhood multiple sclerosis can present as encephalopathy with consciousness disturbance. Lesions in the brainstem activating the reticular formation, including the thalamus, likely cause these symptoms.

Area of Science:

  • Neurology
  • Pediatric Neurology
  • Neuroimmunology

Background:

  • Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system.
  • Pediatric MS often presents differently than adult MS, sometimes mimicking encephalopathy.

Observation:

  • A nine-year-old girl presented with consciousness disturbance, drowsiness, emotional instability, decreased vision, and coordination issues.
  • Cerebrospinal fluid showed elevated IgG and myelin basic protein.
  • EEG revealed frontal slow waves; MRI identified demyelinating plaques in the brainstem, thalamus, and white matter, involving the reticular formation.

Findings:

  • The patient had a history of bilateral optic neuritis and papillitis, supporting the MS diagnosis.
  • Methylprednisolone pulse therapy led to significant improvement in neurological symptoms and MRI findings.

  • Consciousness disturbance in this case was attributed to brainstem lesions affecting the reticular activating system.

    • Implications:

    • Childhood MS may present with severe neurological symptoms resembling encephalopathy.
    • Early diagnosis and treatment are crucial for managing pediatric MS.
    • Understanding the neuroanatomical basis of symptoms can guide therapeutic strategies in pediatric MS.
