Febrile seizure is the most frequent type of seizure in childhood occurring in 2-4% of children under the age of 5. Although pathogenesis of seizure following fever is not well understood, multiple risk factors are known to contribute to its precipitation. One of the possible risk factors which had not been mentioned yet in reference texts and still is in the research phase is a serum sodium level below the normal limits which specially plays a role in the recurrence of febrile seizure. In this descriptive retrospective study records of 400 in-patients cases of primary episodes of febrile seizure in Bahrami children hospital in the years of 1996-1997 were reviewed. 214 (53.5%) cases had serum sodium levels of <135 m.mol/L. The mean serum sodium level for all the cases was 135.28±4.65 m.mol/L which is considerly less than the serum sodium level of 140±0.8 m.mol/L seen in healthy children. There was no significant difference in serum sodium levels different sex and age groups in this patient population
