Summary

Chorea in patients with Acquired Immunodeficiency Syndrome (AIDS) has varied causes, including infections and HIV encephalopathy. Early diagnosis requires thorough clinical and neuroradiological assessment, especially in young patients without a family history of movement disorders.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Neuroimaging

Background:

  • Choreic movements can manifest in patients with Acquired Immunodeficiency Syndrome (AIDS).
  • Understanding the diverse etiologies of chorea in this population is crucial for effective management.
  • This study investigates the clinical and anatomical correlates of chorea in a series of AIDS patients.

Observation:

  • Five consecutive AIDS patients presenting with choreic movements were analyzed.
  • Movement disorder presentations included focal choreic dyskinesias, hemichorea, and generalized chorea.
  • Onset varied from acute and febrile to subacute, with chorea appearing as an initial or later symptom of AIDS.

Findings:

  • Identified causes of chorea in AIDS patients included cerebral toxoplasmosis, progressive multifocal leukoencephalopathy, subacute HIV encephalopathy, and iatrogenic factors.

  • Chorea can be the presenting symptom of AIDS or a neurological manifestation following diagnosis.
  • Buccofacial dyskinesias were observed following bacterial encephalitis in one patient.

    • Implications:

    • Chorea is a recognized, albeit variable, manifestation in AIDS patients.
    • Accurate diagnosis necessitates comprehensive clinical evaluation and advanced neuroradiological imaging.
    • In young individuals with unexplained chorea and no family history, AIDS-related neurological disorders should be considered in the differential diagnosis.
