Memory and epilepsy: characteristics, course, and influence of drugs and surgery

Memory processing in humans is essential for consciousness, cognitive-behavioral development and individual biography. In epilepsy, declarative memory functions show characteristic patterns of impairment when mesiotemporal and associated neocortical structures are affected by lesions, ongoing epileptic activity, or the undesired effects of conservative or operative treatment. Major issues are thus the etiology, onset and course of memory impairment, as well as the prevention of further memory decline during treatment. New input in the field has resulted from improved imaging techniques, sophisticated experimental study designs, more selective surgical approaches, and new antiepileptic drugs.
