This book examines every major aspect of Alzheimer's disease (AD). It provides exciting, comprehensive and up-to-date summaries of the most important recent advances in the genetic, molecular, biochemical, and cell biological studies of AD. There has been no scholarly research volume on AD published in the last 3-5 years. This edition includes expanded coverage of the cellular-level exploration of related dementing disorders, with in-depth presentation of prion diseases, Pick's disease, fronto-temporal disorders, transgenic models, and biochemistry of presenilins. Treatment of symptoms with therapeutic drugs is discussed, along with outcomes of and problems inherent in clinical trials for AD. The studies and advances described in this volume will help to accelerate the process of rational drug discovery and soon serve to extend and enhance the mental health and lifespan of our burgeoning elderly population.
