Whether a child will have sequelae after fever-induced convulsions mainly depends on the underlying cause and the severity of the condition. If the convulsion is caused by typical febrile seizures, it usually does not result in long-term complications. Febrile seizures generally occur in children between six months and five years of age, commonly triggered when body temperature exceeds 38.5°C. Typically, only one seizure occurs during an illness episode, lasting less than several minutes, and such seizures do not affect a child's growth, development, intelligence, or motor abilities. However, if the convulsions are caused by conditions such as meningitis, encephalitis, or epilepsy, they may lead to sequelae. These may include intellectual or motor developmental delays, epilepsy, and other complications, with severity varying depending on individual differences and the specific nature of the illness.
