Children with febrile seizures whose neurological development is normal at the time of the first seizure perform as well as other children in terms of their academic progress, intellectual function, and behavior at 10 years of age.
This is true for children with both simple and complex FS and for those with recurrent FS.
Similarly, when children with febrile seizures are compared with their siblings at the age of 7 years, there are no differences in the mean full-scale IQ scores, and poor academic achievement is as common in siblings as in children who have had febrile seizures.
Furthermore, the mean IQ of those with recurrent seizures and those with seizures lasting 30 minutes or longer is not different from that of their siblings.
Thus, the prognosis for neurological development is excellent.
