This second edition of Seizures and Epilepsy, written almost a quarter of a century after the ground-breaking first edition, is more than an update: it is a complete revision due to tremendous advances in the field. Our understanding of the fundamental neuronal mechanisms underlying epileptic phenomena, as well as current diagnosis and treatment, have been heavily influenced over the past several decades by seminal neuroscientific developments, particularly the introduction of molecular neurobiology, genetics, and modern neuroimaging. According to the World Health Organization, epilepsy accounts for 1% of the global burden of disease, equivalent to breast cancer in women and lung cancer in men. Among primary disorders of the brain, it is equivalent to depression, dementia, and substance abuse. Singly authored by Jerome Engel, Jr, this must-read from 1989 reasserts itself as a modern classic comprehensive textbook covering a broad range of both basic and clinical epileptology.
