Febrile convulsions are also known as febrile convulsions (convulsive seizures due to high fever). Febrile convulsions are not necessarily epilepsy, but can cause epilepsy. The symptoms of febrile convulsions are similar to those of epilepsy, mainly characterized by sudden loss of consciousness, rolling of the eyes, clenching of the teeth, incontinence, and generalized convulsions. Its cause is mainly due to the incomplete development of the central nervous system in infants and young children, when the body temperature rises, the brain cells are overexcited and triggered spasms and other symptoms. After the occurrence of febrile convulsions, first of all, we should exclude whether it is viral encephalitis or due to poisoning, metabolic diseases, epilepsy and other diseases, such as the examination of the existence of the primary disease, should be actively treating the primary disease, if necessary, can be added with phenytoin sodium, carbamazepine and other drugs for treatment. The prognosis of febrile convulsions is generally good, and they do not usually cause epilepsy. However, they may turn into epilepsy if they have frequent seizures. This symptom of febrile convulsions will disappear naturally with age. Therefore, when a patient has a febrile convulsion, he or she should consult a doctor in time, improve relevant examinations and actively cooperate with treatment to avoid causing epilepsy.
