Disorders of sodium and water are common complications of acute infections of central nervous system. (CNS) and are associated with poor outcome. Hyponatremia is the most common electrolyte and water-related disorder among these patients. Brain oedema associated with the primary pathology of the infection can worsen with hyponatremia. A systematic evaluation and management of sodium and water dysregulation in acute CNS infections may contribute to improved outcome.
