High Fever Seizure Outlook
- Febrile seizures resolve quickly.
- Febrile seizures do not damage the brain.
- About 30 percent of children who experience a febrile seizure will have a second febrile seizure.
- About 10 percent of children who experience a febrile seizure will have three or more seizures.
- In the general population, about 1 child out of every 100 children will develop epilepsy by age 7.
- If a child has had one febrile seizure, the risk of developing epilepsy increases slightly.
- If a child has a febrile seizure prior to 12 months of age or has multiple febrile seizures, the risk of developing epilepsy roughly doubles.
- The risk of developing epilepsy is about 40 times greater in children who have one or more complex febrile seizures (seizures that last for longer than 15 minutes).
