What Is a Tonic Seizure?
Epilepsy tonic seizures are characterized by sustained and strong contraction of muscles, which keeps the trunk or limbs fixed in a certain position, which is more common in children and adolescents, and often occurs during sleep. Epilepsy tonic seizures can last from 5-20 seconds, mainly involving the neck, trunk, and proximal limbs, and are a primitive form of exercise. Animal experiments show that tonic seizures mainly originate from the brainstem, especially the reticular structure of the lower midbrain and pontine.

- More common in children and adolescents. It occurs more frequently during sleep. It is a slow and continuous contraction of systemic muscles. Because the intensity of muscle contraction varies in different parts, the patient's limbs are fixed in a certain posture. , Trunk forward or backward, and some will appear in situ circle, facial deformation, dilated pupils, breathing stops. Seizures can last from seconds to tens of seconds. At the same time accompanied by loss of consciousness, some are also associated with autonomic disorders, and even more serious. Immediately awake when the onset stops. During the onset, most of the EEG showed low-level recordings, and a few showed fast waves or high amplitudes. [1]
- Frequent tonic seizures can constitute a persistent state of tonic seizures, lasting up to several days, with less conscious disturbances, and autonomic symptoms are generally more severe, especially increased saliva and bronchial secretions.
