In children with seizure-onset FS, whether SFS, CFS, PFS, or FSE, EEG is usually not required to assess the condition. Even if the EEG results are abnormal, the EEG is not predictive of recurrent FS or secondary seizures G. Non-specific slow waves are often seen in the posterior head during EEG monitoring within 2 weeks after the onset of FS. Therefore, if an EEG is needed, it should be scheduled 2 weeks after a convulsive seizure or reviewed 2 weeks after its occurrence. During the follow-up period, there is generally no indication for EEG in SFS, while follow-up EEG is often required for CFS with risk factors for epilepsy G, and routine follow-up EEG is required for PFS or FSE. Therefore, EEG should be required only when there is a high suspicion of epileptic G and should be used to define the type of epileptic G rather than to predict its occurrence. EEG monitoring should be performed for at least 30 min, including awake EEG and sleep EEG, according to international guidelines.
