Fever seizures

Fevers that lead to a fever seizure may develop so quickly that parents did not even realize that their child's temperature was rising.

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.
