[Apparently unprovoked seizures precipitated by prefebrile condition].

We investigated the clinical features of the patients whose body temperature exceeded 38 degrees C, in 0.5-6 hours after an afebrile seizure (prefebrile seizure). Patients with meningoencephalitis and epilepsy were excluded from this study. From May 1995 to April 1997, seven cases of prefebrile seizures admitted to PL hospital. Three of the 7 had a status and one had a cluster of seizures. Five patients had had several febrile seizures prior to the onset of prefebrile seizures. One developed epilepsy during the follow-up period. We speculate that prefebrile seizures have several factors of complex febrile seizures and require a careful follow-up.
