Febrile seizures are the most prevalent type of seizure in children, affecting 2–5% of children between six months and six years of age1.
After experiencing a first episode, approximately two-thirds of children do not encounter further febrile seizures2. On the other hand, one-third may experience recurrenct febrile seizures until the age of six. Although these seizures can be alarming for caregivers, those lasting under 15 minutes typically do not result in long-term health issues, such as brain damage. However, febrile seizures exceeding 30 minutes can lead to serious complications, such as oxygen deprivation to the brain, hence the importance of not allowing seizures to persist for extended periods. Only 3% of children with febrile seizures may eventually develop epilepsy, a condition involving seizures not related to fever3.
