Febrile seizures

Abstract

Febrile seizures are the most frequent of seizure disorders in childhood. Febrile seizures are most common in children between 6 months and 3 years of age, with a peak incidence at about 18 months. Approximately 30% to 40% of children who experience a febrile seizure will have a recurrence. The majority of febrile seizures occur within 24 hours of the onset of the fever. Febrile seizures can be simple or complex. Diagnostic studies are usually not necessary. Febrile seizures usually are self-limited, and intervention to stop the seizure often is unnecessary. When possible, the cause of the fever should be treated. Continuous preventative anticonvulsant therapy is not recommended for children with either simple or complex febrile seizures. The use of intermittent anticonvulsant therapy is not routinely indicated. Parental educational and counseling is important. The prognosis is excellent.
