Sydenham chorea in a child led to parkinsonian symptoms like bradykinesia and rigidity. Autoimmune antibodies, possibly triggered by streptococcal tonsillitis, may cause these reversible neurological signs.

Area of Science:

  • Neurology
  • Immunology
  • Pediatrics

Background:

  • Sydenham chorea is a common manifestation of pediatric autoimmune neuroinflammatory disorders.
  • Parkinsonism is characterized by bradykinesia, rigidity, and tremor, typically associated with neurodegenerative conditions in adults.

Observation:

  • A 10-year-old girl presented with acute bradykinesia and rigidity during an episode of Sydenham chorea.
  • These parkinsonian motor signs showed significant improvement over a six-month period.

Findings:

  • Serum analysis revealed elevated anti-streptolysin-O (ASO) titers and anti-basal ganglia antibodies (AGBA).
  • The presence of these antibodies suggests an autoimmune response directed against basal ganglia structures.

Implications:

  • This case suggests that post-streptococcal autoimmune processes can induce transient parkinsonian symptoms in children.
  • It expands the spectrum of central nervous system (CNS) disease following streptococcal infections.
  • Further research into autoimmune mechanisms in pediatric movement disorders is warranted.
