Depending on its cause, duration, and age of the population studied, mortality from status epilepticus (SE) is significantly increased, with case fatality rates ranging from 4.6% to 39%. These data are alarming! In addition to the prognosis of SE, this book highlights recent advances in the definition, EEG characteristics, and management of SE in adults and children. It is easy to read and contains the essential elements that the emergency physician needs to recognize SE, particularly in its subtle presentation of nonconvulsive status epilepticus (NCSE) as succinctly described in one of the chapters.
