After the first febrile convulsion, only about 30% of children overall will have a recurrence of febrile convulsions during subsequent febrile illnesses. Risk factors for recurrence of such febrile convulsions include: (1) onset before 18 months of age; (2) temperature <38°C at the time of the febrile convulsion; (3) family history of febrile convulsions; and (4) short duration of fever (<1 h) before the onset of the febrile convulsion. In children with all risk factors, 76% will have recurrent febrile convulsions, while only 4% of children without all of the above risk factors will have recurrent febrile convulsions. The majority of children with febrile convulsions have good intellectual-motor development, and even in children with complex febrile convulsions, there are no significant differences in long-term intellectual-motor and behavioral development compared to children of the same age.
