Epilepsies with identified cause represent about 36% of all late onset epilepsies (> 18 years). This percentage is higher in late adult life (> 40 years) than in early adult life (18-40 years). Predominant aetiology is head injury, in the former period and cerebrovascular disease in the latter one. Brain tumors show a similar percentage. The remaining aetiologies (inflammatory, post-encephalopathic, degenerative) have a low incidence (about 2%). Idiopathic epileptic syndromes (Awakening Grand Mal, Benigne Juvenile Myoclonic Epilepsy, Juvenile Absence Epilepsy) rarely begin in adult life (about 4% of the late onset epilepsies). Tumoral, vascular and multiple sclerosis aetiologies were examined in detail. From this review it appears that about 60% of adult life epilepsies still show an unidentified cause. This surprising data requires further investigations.
