Türk Çocuklarında İdiopatik Çocukluk Çağı Oksipital Lob Epilepsisi

Abstract

Purpose: Two forms of idiopathic occipital lobe epilepsy can be distinguished: an early onset or Panayiotopoulos type (PS), and a late onset or Gastaut type (GS). The aim of this study was to identify clinical manifestations and outcome in Turkish children with idiopathic occipital lobe epilepsy. Material and Methods: Thirty nine children (27 boys, 12 girls) were divided into the PS and GS type, according to the classification for epileptic seizures of the International League Against Epilepsy. Results: Among the 39 patients, 27 (69.3%) were boys and 12 (30.7%) were girls and the mean age at the seizure onset was 77.38 ± 27.33 months (36-145 months). The PS type patients consisted of 27 children (19 boys, 8 girls). The average age of seizure onset in PS type patients was 60.76 ± 14.21 months (range, 36-94 months). The GS type patients consisted of 12 children (8 boys, 4 girls), and seizure onset was 107.7 ± 18.8 months (range, 72-145 months).Ictal vomiting was more common in the PS type patients, and visual symptoms were more common in the GS type patients. We detected that after treatment, 27 patients (100%) in PS type and 10 patients (83.3%) in GS type became seizures-free. Two patients continued having seizures in GS type. Conclusions: The average age of seizure onset was much younger in the PS than in the GS. Also, in idiopathic occipital lobe epilepsy, the PS type has better seizure-free and prognosis than the GS.
