The recurrence rate of seizure within two years is 35% to 40% in patients with a first-time unprovoked seizure. Status epilepticus occurs in about 6%-7% of the patients with seizure in the emergency department (ED). The overall mortality rate of status epilepticus is approximately 22% (3% in pediatric patients to 26% in adults). Simple febrile seizures are considered normal in childhood and the prognosis is generally excellent. The recurrence rate is about 12% in children that have their first febrile seizure in infancy and about 50% in those who have their first febrile seizure later.
