A rare case of parkinsonism linked to hyperparathyroidism is presented. Surgical removal of a parathyroid adenoma resolved levodopa-resistant symptoms, suggesting hypercalcemia may worsen parkinsonism.

Area of Science:

  • Neurology
  • Endocrinology
  • Metabolic Disorders

Background:

  • Parkinsonism is a neurological disorder characterized by tremors, rigidity, and bradykinesia.
  • Hyperparathyroidism is a condition involving overactive parathyroid glands, leading to elevated calcium levels.
  • Levodopa is a primary medication for managing Parkinson's disease symptoms.

Observation:

  • A 70-year-old woman presented with levodopa-resistant parkinsonism as her primary symptom.
  • Investigations revealed underlying hyperparathyroidism.
  • Surgical excision of a parathyroid adenoma was performed.

Findings:

  • The patient's parkinsonism symptoms significantly improved following parathyroid adenoma removal.
  • Post-operative hormonal and chemical profiles normalized.

  • This rare case highlights a potential link between hypercalcemia and parkinsonism severity.

    • Implications:

    • Hypercalcemia associated with hyperparathyroidism may act as an aggravating factor in levodopa-resistant parkinsonism.
    • This suggests that screening for hyperparathyroidism could be beneficial in patients with unexplained or refractory parkinsonism.
    • Further research is warranted to elucidate the mechanisms by which calcium levels influence parkinsonian symptoms.
