    Hyperparathyroidism can cause complex neurological symptoms, including confusion and asterixis. Correcting high calcium levels resolved these neurological issues and cerebrospinal fluid abnormalities, indicating a direct link.

    Area of Science:

    • Neurology
    • Endocrinology
    • Biochemistry

    Background:

    • Hyperparathyroidism is a condition characterized by excessive parathyroid hormone production, leading to hypercalcemia.
    • Neurological manifestations of hyperparathyroidism are diverse but typically less severe than reported in this case.
    • Cerebrospinal fluid (CSF) abnormalities in hyperparathyroidism are rare, making this case noteworthy.

    Observation:

    • A patient presented with severe neurological symptoms including mental confusion and asterixis.
    • Cerebrospinal fluid analysis revealed elevated protein levels and marked pleocytosis.
    • These neurological and CSF findings were observed in the context of undiagnosed hyperparathyroidism.

    Findings:

    • The patient's neurological symptoms and CSF abnormalities resolved completely after correction of hypercalcemia.

  • This suggests a direct pathophysiological link between metabolic disturbance (hypercalcemia) and neurological dysfunction.
  • The findings highlight the potential for significant neurological impact from severe hyperparathyroidism.

    • Implications:

    • This case underscores the importance of considering metabolic disorders like hyperparathyroidism in patients with unexplained neurological symptoms.
    • It suggests that prompt correction of hypercalcemia can reverse severe neurological deficits and CSF abnormalities.
    • Further research may elucidate the precise mechanisms by which hypercalcemia affects the central nervous system and CSF composition.
