Abstract: Detailed knowledge of electroencephalographic patterns accompanying epileptic seizures in children is paramount to the correct identification of epileptic seizures and syndromes. In this article, we present a review of ictal patterns of different seizure types in children, illustrating with examples collected in our video-EEG laboratory at Pequeno Príncipe Hospital.Keywords: electroencephalography; epilepsy; ictal pattern. RESUMO Padrão ictal em crianças: uma revisão ilustradaO conhecimento detalhado dos padrõ… Show more

“…The proposed dynamical scenario of state transitions has some interesting features that are in agreement with EEG findings for common types of seizures such as tonic–clonic and absence seizures. Abrupt onset and abrupt termination of the seizures, progressive increase in amplitude and decrease in frequency during ictal phase 76 79 and sensitivity to rhythmic stimulations such as flashing or light flickering at certain frequencies can be explained by this conceptual model. Epileptic seizure in photosensitive epilepsy patients is most frequently induced by 15 Hz flicker stimulus when the eyes are open 80 and 10 Hz stimulus when the eyes are closed 81 , which can confirm the resonance nature of epileptic seizures.…”

“…The epileptiform discharges differ depending on the specific epilepsy syndrome and seizure types [ 3 ]. Typical absence seizures consist of 3-Hz frontally predominant generalized spike-and-wave (GSW) discharges in childhood absence epilepsy and relatively faster frequencies in juvenile absence seizures.…”

“…Ictal patterns in these children vary widely according to seizure type and epilepsy syndrome. The literature on the ictal EEG [ 3 ] recording for absence seizures describes 2.5 to 4 Hz generalized spike-and-wave (GSW) discharges in typical absence seizures, generalized polyspike waves at 3 to 6 Hz with eyelid myoclonia and slower frequencies of < 2.5 Hz in atypical absence seizures. Fakhoury & Abou-Khalil [ 4 ] & Tatum et al [ 5 ] have described polyspike ictal-onset of absence seizure in adults.…”
