Factors that increase the risk of having a febrile seizure include:

  • Young age. Most febrile seizures occur in children between 6 months and 5 years of age. It's unusual for children younger than 6 months to have a febrile seizure, and it's rare for these seizures to occur after 3 years of age.
  • Family history. Some children inherit a family's tendency to have seizures with a fever. Additionally, researchers have linked several genes to a susceptibility to febrile seizures.
