In a cross sectional study over a period of two years (Sep 1997-Sep 1999), 107 children with febrile convulsion were evaluated in Firooz-Abadi Hospital.

  The mean age of first occurrence of febrile convulsion was 20.5 ± 9.8 months and for children with a family history of febrile seizure was 14.8 ±8.02 months.

  In those without a family history the mean age were 22.1±9.7 months.

  A male preponderance (60%) was observed. There was a predominance of generalized seizures (81%). The duration of convulsions in the majority of children (85%) were less than 15 minutes. Children with a positive family history were at increased risk of recurrent febrile seizures.
