The frequency of development of nonfebrile seizures in 116 children who had experienced at least one febrile convulsion and were followed for more than five to eight years was 4.3% (5 cases). Of these, three cases had prolonged generalized convulsions of the clonid type. (2) The risk factors identified as nonfebrile seizures after febrile convulsions, were the preexisting neurological abnormality or developmental retardation, focal features and more than a 10-minute duration of the first febrile convulsions, and abnormal paroxysmal discharges at the initial interietal EEG recordings.
