Clinical study of epilepsy with severe febrile seizures and seizures induced by hot water bath

We followed five cases with severe febrile seizures (FS) with early onset and seizures induced by hot water bath, indicating severe myoclonic epilepsy in infancy (SME) or the peripheral form of SME. These cases, however, had far better clinical courses than that of SME or the peripheral form of SME. These cases were characterized by: (a) severe FS with early onset and seizures induced by hot water bath; (b) a lack of myoclonic seizures; (c) no psychomotor deterioration; (d) no underlying disorders or signs of brain insult on neurologic and laboratory examination; (e) relatively successful seizure control; (f) none of the severe EEG abnormalities seen in SME and the peripheral form of SME; and (g) a positive family history of convulsive disorders.
