Because some parents are overly concerned about their children, they suspect some conditions that can occur in normal children as seizures, and non-epileptic tonic-like seizure less is one of them. A non-epileptic tonic-like seizure is a non-epileptic seizure, which is a behavior that can be seen during normal pediatric development, and the cause is not well understood. No treatment is needed. It is commonly known as “playing heylo” and “playing hard” in northern China. In 1976, Vanasse reported tremulous seizures, which are similar to this seizure, but the age of onset can be up to 3 years old, and some children stop having seizures only at 5 years old, which is different from our experience. 1. The seizures occur during wakefulness and not during sleep. 2. The seizures are characterized by staring with both eyes, clenching teeth, head trembling (rapid shaking of the head from side to side), head slightly tilted back or forward, both arms raised, fist clenched when flexing, whole body forceful trembling (whole body shaking slightly), and occasional “humming” sound. 3. The seizure lasts for a short time, a few seconds. 4. Special movements of the lower extremities are rare, and there is no corkscrew. 5. Consciousness is always clear throughout the process. 6. Sometimes the seizure can be triggered by speech or posture. Seizures can be interrupted by external stimuli. 7. Return to the original state immediately after the seizure. 8. The EEG is normal during the interictal period and during the seizure. 9. Does not affect intellectual development. 10. The seizures gradually disappear with age and stop around the age of 1 year. Differentiation: It should be differentiated from seizures (e.g. infantile spasms, benign infantile myoclonus), hypocalcemic convulsions or emotional cross-legged movements. Treatment: No treatment is necessary.
