Hyponatraemia is usually defined as a serum sodium concentration below 135 mmol/1. The condition is rarely symptomatic until serum sodium falls below 120 mmol/1 and symptoms are more usually associated with values around 110 mmol/1. These symptoms include confusion and restlessness, progressing to drowsiness, myoclonic jerks, generalised convulsions and eventually coma. In a general hospital population about 1% of patients develop hyponatraemia (Rutsky, 1992), whereas in psychiatric patients the prevalence has been reported to range from 3.3% to 12.2% (Ohsawa et al, 1992).
