Seizures usually have a sudden onset without warning, even if the seizure is not recommended to be stopped with a warning, to make it easier to determine the type of seizure for treatment.
Seizures are episodic in nature, that is, the symptoms occur suddenly without warning, last for a period of time and then return to normal; and the seizure is brief, usually a few seconds or minutes.
If a seizure has an aura, it is usually too late to stop it, and stopping it is not recommended; stopping the seizure may not accurately determine the type of seizure it is, and does not make it easy to target treatment.
Most epilepsy, with regular medication, can be well controlled. If seizures are frequent, it is recommended to consult a hospital in time to adjust the treatment.
