What characterizes most febrile seizures in children?

Most febrile seizures in children are characterized by generalized tonic-clonic activity and a duration of less than 15 minutes. These seizures typically occur in young children, often during a rapid rise in body temperature, which is commonly associated with infections. The generalized tonic-clonic aspect means that the seizures involve both sides of the body and include muscle stiffening (tonic) followed by rhythmic jerking (clonic).

The time frame of less than 15 minutes is critical; seizures that last longer than this duration are less common in typical febrile seizure cases and may warrant further medical evaluation. In most instances, after a febrile seizure, children will return to their baseline state without significant postictal confusion or prolonged recovery, differentiating these seizures from other types that can have a more extended postictal phase. This understanding helps caregivers and medical professionals respond appropriately to febrile seizures without unnecessary alarm.
