Although it has been known for 100 years that cognitive functioning is impaired in schizophrenia, the implications of this impairment have only recently been clearly understood. While in the past, cognitive deficits were thought to be the result of other aspects of the illness, such as poor co- operation, or as a result of the treatment of the illness, it is now known that these factors exert only a very minor influence on cognitive deficit. This book, with contributions from the major international names in the field, reviews the most recent research on the impairment of cognitive functioning in schizophrenia, covering: what it is, how wide-ranging it can be, what the clinical implications are, and how it can be treated? The book is divided into three sections. The first section provides background information on the important aspects of cognitive functioning in schizophrenia. The second section provides information on the correlates of cognitive functioning, examining classical symptoms of the illness, as well as social and adaptive functional deficits. The final section provides information on the treatment of cognitive functioning in schizophrenia, from the older less effective treatments with conventional antipsychotics, to the developing treatment strategies using experimental compounds. A clear insight into cognitive deficit is the key to understanding why previous treatments have failed, and the key by which new treatments may change this terrible illness, treatments significantly more effective than earlier interventions.

New developments in the basic and clinical neurosciences have lead to important advances in our understanding of the events that occur between conception and birth that can influence schizophrenia. At the other end of the life span, some of the most exciting developments in years have recently been coming out of comprehensive studies of post-mortem studies of patients with schizophrenia. In the clinical domain, studies of first episode patients with schizophrenia are proliferating, at the same time as many research groups are performing comprehensive studies of patients with schizophrenia who are in the eighth decade of life or even older. Thus, many of the exciting new developments in research on schizophrenia are at the ends of the life span, suggesting that a wide-ranging treatment of schizophrenia in this framework will be very well accepted.This volume is unique in adopting a lifespan approach to understanding schizophrenia. There are many aspects of schizophrenia that require research attention from a lifespan perspective. For example, there may be aspects of the behavior or biological functioning that are present before the illness that change an individual's risk for developing the illness. There may be environmental events that can cause schizophrenia in the absence of other predisposing factors. There may be genetic influences on the development of schizophrenia that are modified by environmental events, either psychological or physiological. Factors such as an individual's gender or intelligence may also influence schizophrenia, either in terms of changing the risk for development or changing aspects of the illness' presentation, such as onset age or overall functional outcome. With contributions from leading scientists in this field, and results from the frontiers of schizophrenia research, this volume is a major new addition to the psychiatry literature.
