Abstract

Introduction: Hyponatremia is a common electrolyte abnormality in hospitalized patients. It could be mild with nausea and vomiting or severe with lethargy, seizures, and loss of consciousness. In the critically ill, especially neurocritically ill patients, hyponatremia is also a common electrolyte disorder and is associated with clinical prognosis. Hyponatremia may induce neurological complications including cerebral edema, increased intracranial pressure (ICP), seizures, altered mentality, and brain death due to exacerbation of brain edema. In addition, neurocritically ill patients may be more vulnerable to hyponatremia and may develop clinical symptoms in the absence of severe hyponatremia.
