Longterm Follow-Up of Childhood Epilepsy with Absences - II. Absence-Epilepsy with Initial Grand Mal

Abstract

The study deals with 83 patients with absence epilepsy which had started with generalized tonic clonic seizures. Only those patients were included, who could be followed up to an age older than eighteen years. The patient population is heterogeneous; it includes numerous older patients in whom therapy had been instituted at a time when the present standard medication with ethosuximide and valproate was not available. Therefore the data cannot be used as a basis for global statements concerning the prognosis of absence epilepsy with grand mal onset. - About 80 % of the patients treated with standard therapy became seizure free. An unfavourable course was mainly preceded by incorrect, irregular and quantitatively inadequate therapy. Standard therapy cannot prevent singular generalised tonic clonic seizures in the late course. The social status of adult patients is mainly favourable if they are seizure free. Sporadic attacks usually will not impair social integration. In all, absence epilepsy starting with grand mal responds not as well to therapy and has a more unfavourable social prognosis than epilepsy starting with absences.
