Summary

Late-onset metachromatic leukodystrophy (MLD) can present with unusual psychiatric symptoms like psychosis and movement disorders. Early diagnosis requires advanced imaging and biochemical testing for this rare genetic disorder.

Area of Science:

  • Neurology
  • Neuroscience
  • Medical Genetics

Background:

  • Metachromatic leukodystrophy (MLD) is a rare lysosomal storage disease.
  • It results from arylsulfatase A deficiency, leading to myelin sheath destruction in the nervous system.
  • Late-onset forms often present with atypical neurological and psychiatric symptoms, complicating diagnosis.

Observation:

  • A case of late-onset MLD is presented with a unique clinical manifestation.
  • The patient exhibited paranoid hallucinatory psychosis and severe dyskinesia.
  • The atypical presentation initially delayed diagnostic procedures.

Findings:

  • Diagnostic procedures were initiated due to the unusual clinical course.
  • Magnetic Resonance Imaging (MRI) played a crucial role in identifying white matter abnormalities.

  • Specific biochemical tests confirmed the diagnosis of metachromatic leukodystrophy.

    • Implications:

    • This case highlights the importance of considering rare genetic disorders in patients with unexplained neurological and psychiatric symptoms.
    • Advanced neuroimaging and biochemical analyses are essential for the accurate diagnosis of atypical MLD.
    • Timely diagnosis can potentially lead to earlier intervention and improved patient management strategies.
