Febrile convulsions: when children suffer from certain infectious diseases, such as upper respiratory tract infections, encephalitis, meningitis and other diseases, it is easy to cause fever symptoms, when there are symptoms of high fever, especially when the body temperature rises sharply, if the fever is not reduced in time to deal with it, it is very likely to induce febrile convulsions, which can cause convulsions. 3. Seizures: some children have a history of epilepsy, stimulated by certain adverse factors, such as emotional factors, dietary factors, environmental factors and other factors, prone to cause seizures, may show symptoms of convulsions, may also be accompanied by loss of consciousness, foaming at the mouth and other manifestations.
