A febrile convulsion is a fit or seizure that occurs in children when they have a high fever. This can happen in children aged six months to five years.One in every 20 children will have one or more febrile convulsion. A febrile convulsion is not epilepsy and does not cause brain damage. Around 30 to 35 per cent of babies and children who have had one febrile convulsion will have another.
In a simple febrile convulsion, where the focus of infection can be identified, blood tests and invasive investigations are often NOT indicated. Recurrence rate depends on the age of the child; the younger the child at the time of the initial convulsion, the greater the risk a further febrile convulsion (1 year old 50%; 2 years old 30%).
