Perisylvian epileptic network revisited

Thirteen years ago, we provided evidence for a unifying concept of idiopathic focal childhood epilepsies (IFCE): Rolandic epilepsy (RE), Panayiotopuolos syndrome (PS), Gastaut type childhood idiopathic occipital epilepsy,* Landau – Kleffner syndrome (LKS) and Electrical Status Epilepticus in Sleep (ESES) **. We treated them as a spectrum of disorders featured by a shared transient, age-dependent, genetically based, non-lesional and localized epileptic abnormality. The nature of this spectrum disorder is still not entirely clear.
