Arousal EEG without clinical manifestations of disseminated epileptiform discharge status is rare, the authors for the first time reported a case of this rare EEG in children up to 9 years. Female, 8 years old, July 1984 due to the onset of episodic loss of consciousness, binocular strabismus admission. Had had mumps and fever before admission, no family history of epilepsy. Nervous system examination and normal cerebrospinal fluid. EEG was traced for the first time 13 hours after the epileptic seizure, showing a 2.5- to 3.5-Hz spike (SW) sustained synchronously on both sides of the epicardium. This abnormal EEG was inhibited when exposed to the open eye and was affected by rhythmic δ activity and transient irregularities SW replaced. Children with unconscious changes in EEG tracings, no seizures and behavioral abnormalities. Intravenous clonazepam 2mg, EEG no change, discharged without treatment. At 9 years of follow-up, the EEG remained essentially unchanged, mental activity such as counting, and EEG did not change significantly when answering questions. Excessive ventilation, flash
