The first febrile seizure is a frightening moment for parents. Most parents are afraid that their child will die or have brain damage. However, simple febrile seizures are harmless. There is no evidence that they cause death, brain damage, epilepsy, a decrease in IQ, or learning problems.
Most children outgrow febrile seizures by age 5.
Few children have more than three febrile seizures in their lifetime. The number of febrile seizures is not related to future risk of epilepsy.
Children who would develop epilepsy anyway will sometimes have their first seizures during fevers. These seizures most often do not appear like a typical febrile seizure.
