II. Pathophysiology

  1. Childhood Movement Disorder
  2. Occurs within 6 months of Streptococcal infection
    1. Specifically Group A Beta Hemolytic Streptococcus
  3. Late manifestation of Rheumatic Fever

III. Epidemiology

  1. Incidence: <5% of Rheumatic Fever cases
  2. Ages: 5 to 15 years

IV. Symptoms: Gradual onset of neurological symptoms

  1. Atypical behavior
    1. Irritability and crying

  3. Motor weakness
  4. Inaccurate voluntary motions
  5. Clumsiness
  6. Hypotonia
  7. Diminished Deep Tendon Reflexes
  8. Speech Impairment (Dysarthria)
  9. Asymmetric (one side usually more affected than other)

VI. Labs: Cerebrospinal fluid

  1. Intracerebral pressure (opening pressure) increased
  2. CSF Glucose increased
  3. CSF Leukocyte count increased
  4. Late manifestation results in negative markers
    1. ASO Titer negative
    2. Acute phase reactants negative

VII. Prognosis

  1. Self limited
  2. Expect complete recovery within 3 to 6 weeks
