Study Notes
Definition of Febrile Seizures
- Febrile seizures occur between the age of 6 and 60 months with a temperature of 38°C (100.4°F) or higher
- They are not the result of central nervous system infection or any metabolic imbalance
- They occur in the absence of a history of prior afebrile seizures
Prevalence of Febrile Seizures
- Between 2% and 5% of neurologically healthy infants and children experience at least 1 febrile seizure, usually simple
Impact of Complex Febrile Seizures
- Complex febrile seizures may have an approximately 2-fold long-term increase in mortality, as compared to the general population, over the subsequent 2 years
- This increased mortality is likely due to coexisting pathology
Risk Factors for Recurrence of Febrile Seizures
- Age is a major risk factor for recurrence
