Epilepsies with Astatic Seizures of Late Onset

Abstract
In 17 patients with a long course of epilepsy astatic seizures became apparent after the age of 14 yr. In the patients'' childhood astatic seizures were observed. The patients suffered from epilepsies with absences and awakening grand mal or psychomotor fits and sleeping grand mal. The EEG revealed spike-wave variant and spike-and-wave complexes as in the Lennox-Gastaut syndrome. Age dependency of Lennox-Gastaut syndrome was discussed. This type of epilepsy can be understood as a Lennox-Gastaut syndrome of late onset.
