AIM OF THE STUDY: The aim of this study was to determine the frequency of simple and complex febrile seizures, depending on the age, and to determine the risk of recurrence, depending on the age when they first appeared. One of the goals was also to determine clinical characteristics of febrile convulsions. STUDY DESIGN: The study is structured as a cross-sectional research which included children with febrile seizures, treated at the County General Hospital Požega. PARTICIPANTS AND METHODS: This study included 50 children with febrile seizures examined between 2010 and 2017. Data on age, sex, positive family history, age when the first febrile seizures appeared, the occurrence of pathological EEG and neurological status before and after the seizures as well as the number of recurrences were extracted from medical records. The data was processed by the MedCalc Statistical Software version 17.8.2 statistical program. RESULTS: 17 (34%) test subjects reported recurrence. When it comes to the children with two recurrences, the age of the first seizures was significantly higher, with the median of 19 months compared to the children with one recurrence. There is a significant positive link between the number of recurrences and the age of the first seizures, i.e. the children who were older when they had their first recurrence had higher number of recurrences. CONCLUSION: Younger children had febrile seizures due to the underdevelopment of the brain and had more frequent focal seizures, whilst older children developed more frequent recurrences due to the genetic basis for the development of the seizure. The age of the first seizure is not the only risk factor in developing febrile seizures recurrences.
