What is a loss of body seizure? Is it serious?

As we all know, the most common manifestations of epilepsy are limb convulsions, loss of consciousness, foaming at the mouth, etc. In this case, most people can recognize that a seizure has occurred and immediately choose to seek medical attention. However, in addition, there are many, various manifestations that are not taken seriously by patients and their families and delay the consultation. For example, during the consultation, I ask the patient, “Have you ever suddenly lost your mind, blanked out, or suddenly stopped moving on a regular basis?” Many patients say, “I’ve been having them regularly for years, but I haven’t noticed them”, not knowing that this is also a manifestation of seizures, called “absence seizures”. Typical absence seizures, once called petit mal, are a non-convulsive, brief, generalized type of seizure. The main clinical manifestation is a sudden impairment of consciousness and the EEG is a full-conductance 3 Hz spike-and-slow wave burst. Typical aphasic seizures are one of the main types of idiopathic generalized epilepsies (IGE). Clinical features: typical aphasic seizures are characterized by sudden impairment of consciousness, sudden cessation of ongoing voluntary activities and speech, staring, dull expression, usually without falling, sudden recovery of consciousness after a few seconds to tens of seconds, and continuation of ongoing actions before the seizure, without postictal impairment of consciousness. Some people show this as follows: they are distracted in class, and when they wake up, they suddenly find that the bell has already rung, and their academic performance is deteriorating; they are chatting with others, and suddenly they freeze, do not move, and stare blankly, etc. Another person rides a bicycle to work, and on the way, he passes through a forest that is illuminated by the sun, and the sun shines on the sidewalk, but he regularly falls on his feet and gets bruises, while in the sun or indoors, he does not have this condition. But in the sun or indoors, such a situation does not occur, why? A large number of studies have concluded that flash stimuli can induce an apoplectic episode, and that falls are caused by sudden intermittent flashes of light that induce an apoplectic episode. EEG characteristics: The EEG during the seizure is characterized by widespread 3 Hz (>2.5 Hz) rhythmic spike or multi-spike (no more than 3 spikes) bursts, bilaterally symmetrical and synchronized, with the highest wave amplitude in the anterior head. The EEG background is normal during the interictal period, and there may be a small number of focal or asymmetric spike-and-slow-wave bursts or short bursts, which are not fixed from side to side. Valproic acid is the first-line drug in the treatment of typical aphasic seizures in all countries. In addition, it has been reported that carbamazepine or oxcarbazepine can induce an exacerbation of aphasic seizures. Typical case sharing: A 10-year-old child, whose parents found regular daze when playing badminton, which lasted for a few seconds and improved instantly, and sometimes, suddenly froze during meals and dropped chopsticks in their hands, tunneled to the local hospital for various examinations, and various tests, including cranial MRI, did not find any abnormalities, but the seizures became more and more frequent. The results of the EEG were as follows: widespread 3Hz spike and slow complex wave bursts, and after the anti-epileptic drug was adjusted to magnesium valproate extended-release tablets, the condition improved and the academic performance improved significantly.
