Whether or not febrile convulsions develop into epilepsy is related to more factors such as the severity of the seizure and whether or not there is a family history of epilepsy, and the number of individual differences is too great to specify. Febrile convulsions do not necessarily develop into epilepsy, and there is no clear association between the two. If the duration of febrile convulsions is greater than 15 minutes or if there is more than 1 recurrent febrile convulsion within 24 hours, or if the patient had febrile convulsions before the age of 1 year and has a family history of epilepsy, he or she is more likely to develop epilepsy. Therefore, when a child develops a high fever above 39°C, parents should promptly reduce the child’s fever by taking ibuprofen or acetaminophen with physical antipyretic measures such as ice packs, ice caps, and more water to reduce the fever in a timely manner to avoid febrile convulsions and thus prevent the development of epilepsy. In addition, the presence of high fever in children may mean that there is an infection in the body, so it is recommended to actively seek medical attention to find the cause and treat the cause while symptomatically reducing the fever.
