Children under 6
Febrile seizures are seizures that are triggered by a high temperature. They happen to around 3 or 4 out of every 100 children under the age of 6. They are usually linked to a childhood illness, such as tonsillitis. Febrile seizures are not epilepsy. But children who have had febrile seizures have a higher chance of developing epilepsy when they are older, than children in general.
You can find more information about febrile seizures on the NHS website.
Children aged 6 and over
It’s unusual for a child over the age of 6 to continue having febrile seizures. If they do, they might have a form of epilepsy, and your doctor may want to do some tests to look into this.
The link between febrile seizures and epilepsy
The more febrile seizures they have had, the more likely it is that they will develop epilepsy.
