Febrile convulsions used to be called “high fever convulsions”, but as people became more aware of the disease, it was found that many children would have convulsions when they had a low fever, so it was renamed “febrile convulsions”, which can be clearly understood from the word “fever”. Although its seizure manifestations can be identical to those of epilepsy, it is a different kind of disease from epilepsy. The prognosis of typical febrile convulsions is better than that of atypical febrile convulsions, and the intelligence level of children with both types of febrile convulsions is not significantly lower than that of children of the same age. I was asked by many parents during the live broadcast about the causes of febrile convulsions, how to prevent them and how to treat them, so we can also do some discussions. The cause of febrile convulsions involves a variety of factors, including genetics, brain development and structural abnormalities, etc. Modern medicine generally believes that there is a certain genetic background for febrile convulsions, which is thought to be related to mutations in the sodium channel gene (not all), and there is a tendency for families to cluster, which means that if someone else in the family has a history of febrile convulsions, the risk of the condition occurring in others is much higher than in normal families The risk of febrile convulsions is about 6-7 times higher than in normal families. Prevention of febrile convulsions is mainly about preventing infections and reducing the chance of fever, and the child’s natural frequency of convulsions will decrease. In general, prophylactic antiepileptic drugs are not required for prophylactic treatment, with several exceptions: 1) each fever has a convulsive seizure with a high frequency of fever; 2) each fever has multiple convulsive seizures during the course of the illness; 3) febrile convulsions persist. If any of these conditions are present, medications may be applied as appropriate to prevent convulsive episodes that lead to irreversible brain damage. Febrile convulsions are overall benign disorders, and care should also be taken to differentiate them from other diseases, such as intracranial infections, toxic encephalopathy, and Dravet syndrome. In conclusion, the prognosis for febrile convulsions is relatively good and there is no need to be overly nervous.
