Long-term prognosis of epilepsy in children--a follow-up report beyond 18 years of age.
The long-term prognosis of 185 children with epilepsy, who continued to attend the Clinic for Epileptic Children, the Department of Pediatrics, the University of Tokyo, beyond the age of 18 years, was reported. The length of follow-up varied from three to 20 years, but most of them were followed longer than 10 years. The presumed etiology in these children was divided into a cryptogenic group (124, 67.0%) and a symptomatic group (61). The types of seizures were classified into grand mal (86 cases), focal seizure (27), petit mal absence (4), psychomotro seizure (5), infantile spasms (7), and so on. It may be noted that the highest frequency of grand mal was demonstrated, while the incidences of infantile spasms, myoclonic seizure, and akinetic seizure were low in the series. Only 28 children (15.1%) had complications of physical and/or mental handicaps. The follow-up study revealed that 140 patients (75.7%) had been seizure-free in the last 12 months. One hundred and fifteen of them had no seizures for five years or longer. On the other hand, electroencephalographic abnormalities generally continued for a long time after disappearance of seizures. Eightly-one of well-controlled patients were gradually decreasing the doses of anticonvulsants. As for seizure types, it is noted that focal seizure, psychomotor seizure, and infantile spasms were relatively difficult to be controlled. Except for 27 patients, most of them attended normal schools, including junior colleges or universities, and engaged in various occupations. Fifteen female patients had already married, and out of 13 babies who were born from these patients, there were one with ventricular septal defect, one with mental deficiency, and one with anencephaly, while the rest were entirely normal. Additional problems on withdrawal of anticonvulsants after a long-term seizure-free period, and what a medical system should be for treatment of epilepsy in children up to their adulthood were discussed.
