Accurately predict the sequelae of a febrile convulsions can occur, will become epileptic, have some difficulties. But according to some \"risk factors\" estimated that there is some help.
If of febrile seizures for the first time is simple, and before the convulsion nervous system properly, the incidence of epilepsy is 1%; in febrile convulsion before the abnormal nervous system or for complex febrile convulsion, the incidence of epilepsy is 2%~3%; If before the febrile has any unusual complexity and to attack the nervous system, the incidence of epilepsy is 9%. And reports, in children with febrile convulsion such as abnormal during perinatal period, when into epilepsy is often systemic attack. While other children with febrile convulsion, long convulsion, recurrent attacks, limitations or attack, when later changing to epilepsy, often characterized by psychomotor epilepsy.
In short febrile General prognosis is good, only a very small number of patients with epilepsy can be transformed into, leaving sequelae, the incidence of febrile 2%~7%. When when the following risk factors in children with febrile convulsion, portends changes to increase as a percentage of epilepsy.
(1) complex febrile convulsion, attack time is about 15 minutes long, of limited attacks, below 38 ° c, and a continuous fever attack.
(2) multiple recurrent febrile convulsion.
(3) before the febrile exceptions, anomalies of the nervous system, mental retardation or perinatal disorders.
(4) the first attack at the age of 1 or less.
(5) a history of epilepsy or febrile convulsion at home.
