Introduction: Hyponatremic encephalopathy mortality rate reaches about 50% in some special groups of patients (pediatric, child-bearing age women, etc.) However, morbimortality seems to be much lower in men and elderly population. Methods: A retrospective and observational study on patients with hyponatremic encephalopathy diagnosis was carried out. Results: 47 patients with hyponatremic encephalopathy diagnosis were identified. It was an elderly population (age 69±15 years) with women prevalence. In-hospital mortality was 19.1% and neurological aftermaths in the survivors were 27%. Charlson score and delay to initiate treatment were associated to larger in-hospital mortality. Conclusion: mortality rate observed in our population is less than the one observed in other cohorts, probably due to the fact of being a low risk population. In a logistic regression model, delay in initiating an adequate treatment is associated to larger mortality rate in the studied population.

Keywords : Hyponatremic; Hyponatremic Encephalopathy; Mortality; Neurological aftermaths.
