Child fever, when it rises, will have convulsions. Is this epilepsy?

Patient's question:

Once it is caused by fever

Doctor's answer:

Analysis of the condition: This is known as high fever convulsion. High fever convulsion is very common in children, with an incidence rate of 5% to 10%. It is more frequently observed when the fever exceeds 38 degrees Celsius. During this period, children's brains are in a phase of rapid development in all aspects, and the balance between the excitatory and inhibitory systems is unstable, making them more prone to high fever convulsions. The onset of convulsions usually occurs within 12 hours after the onset of fever, with sudden, brief generalized convulsions appearing during a rapid rise in body temperature, accompanied by loss of consciousness, which recovers quickly afterward. In general, neurological examinations and electroencephalogram (EEG) tests are normal. High fever convulsions can have a significant family history, and genetic factors can be considered a predisposition to convulsions. High fever convulsions are divided into two types: simple and complex. The characteristics of simple high fever convulsions are as follows: convulsions appear shortly after a high fever, with a duration of 5 to 10 minutes, generalized and bilaterally symmetrical convulsions, normal psychomotor development, no epileptic discharges on EEG, and a good prognosis. The characteristics of complex high fever convulsions are as follows: convulsions occur even at low temperatures, with a duration exceeding 15 minutes, frequent attacks often reaching more than five times, convulsions, abnormal neurological signs, abnormal EEG, a poor prognosis, and a risk of developing epilepsy. There is no absolute boundary between these two types, and a comprehensive analysis is necessary.
