[So-called late epilepsy (author's transl)].
411 patients with epileptic seizures manifest only after the age of 25 were investigated as to aetiology, seizure type and frequency and age and sex distribution. Neurological, neuro-radiological and EEG findings are reported: There was a clear prevalence of male patients (67%). Manifestation occurred mainly between 30 and 40 years of age (65%). Most seizures were primarily of the generalized grand mal type (68%). Grand mal with focal onset occurred in 13%, partial seizures in 11%, complex partial seizures (psychomotor seizures) in 5%, the latter plus grand mal seizures in 2% and other types in 1% of the cases. Aetiological factors were: chronic alcoholism (31%), vascular diseases (17%), tumours (12%), traumatic brain lesions (8,5%), toxic metabolic lesions (6%) and other factors (6%). Idiopathic epilepsy of late onset was a rare cause (4%). The aetiology remained unknown in 15% of cases. We found that the differences in age distribution, seizure type and the EEG findings are significant factors in the differential diagnosis and we compared them with those found in similar investigations.
