Fever seizures (febrile seizures) are uncontrolled muscle spasms and unresponsiveness in a child. They usually last 1 to 3 minutes and are seldom serious.
Fever seizures are not a form of epilepsy. A seizure is likely to be fever-related if:
- There is one seizure in a 24-hour period.
- The seizure lasted less than 15 minutes.
- The seizure affected the entire body, not just one side of the body.
- The child is age 6 months to 5 years old.
- The child does not have nervous system (neurological) problems.
- The child has had fever seizures before.
