Between 1 and 4 years of age, other seizure types appear, along with a slowing in the psychomotor development attaining a steady state in the disease progress. seizures typically begin before 1 year of age, the febrile seizures tend to be long (more than 20 min), recur in clusters in the same day and evolve into status epilepticus, sometimes afebrile seizures can also occur initially usually in the context of a vaccination or of an infectious episode, or after a bath but majority of these patients then go on to have febrile seizures, isolated episodes of focal myoclonic jerking are sometimes noted weeks or days before the appearance of the first afebrile seizure and remain isolated or in the hours preceding the first febrile convulsive seizure.
