Pitfalls of EEG in cases of suspected seizure or proven epilepsy in the elderly are related but not limited to the specific morphological EEG abnormalities which are described in this paper. Most frequent pitfalls are in fact related to the current misrepresentations that clinicians have about the interest of EEG, the electro-clinical characteristics of epilepsies in the elderly and the intricate situations related to co-morbidity and polytherapy. Beside these « electro-clinical pitfalls », reliable EEGs and video-EEGs, performed by qualified professionals, are more and more difficult to obtain.
