Severe hyponatremia, a dangerous drop in serum sodium, can cause serious neurological issues. Prompt electrolyte correction is key for patient recovery and preventing long-term complications.

Area of Science:

  • Neurology
  • Internal Medicine
  • Endocrinology

Background:

  • Severe hyponatremia (serum sodium < 120 mmol/l) is linked to significant morbidity and mortality.
  • Medical treatments can precipitate hyponatremia and neurological complications.

Observation:

  • Three patients presented with severe hyponatremia and neurological symptoms post-treatment.
  • Two patients experienced seizures and coma, recovering within 24 hours after electrolyte correction.
  • One patient developed central pontine myelinolysis with significant motor deficits, showing marked improvement over three months.

Findings:

  • Hyponatremia can manifest with diverse and severe neurological deficits.
  • Timely correction of electrolyte imbalances is crucial for neurological recovery.

  • Central pontine myelinolysis, though severe, may show substantial recovery.

    • Implications:

    • Clinicians must be vigilant for hyponatremia in patients receiving diuretics, sodium-free infusions, or post-operatively.
    • Early recognition and management of hyponatremia can prevent severe neurological sequelae.
    • Understanding the neurological manifestations of hyponatremia aids in patient management and prognosis.
