Most febrile seizures produce no lasting effects. Simple febrile seizures don't cause brain damage, mental retardation or learning disabilities, and they don't mean your child has a more serious underlying disorder.

Febrile seizures don't indicate epilepsy, a tendency to have recurrent seizures caused by abnormal electrical signals in the brain.

Recurrent febrile seizures

The most common complication is the possibility of more febrile seizures. The risk of recurrence is higher if:

  • Your child's first seizure resulted from a low fever.
  • The period between the start of the fever and the seizure was short.
  • An immediate family member has a history of febrile seizures.
  • Your child was younger than 15 months at the time of the first febrile seizure.
