A state-of-the-art title, this handbook describes the most up-to-date knowledge on cognition in schizophrenia. Cognition is perhaps the most critical aspect of the schizophrenic illness. For the first time, the authors assess the importance of cognition as an independent symptom domain, including an analysis of the costs of impairment. They focus on all the essential features of cognition in schizophrenia and discuss the clinical implications of these deficits in the everyday life of patients. New medications enhance cognition without influencing the psychotic symptoms of the illness, and the most recent data on those effects is included, as is a unique review of cognition and aging. Authoritative and timely, the book provides a concise but sophisticated analysis of cognitive deficits, their implications and developing treatment strategies. Any clinician who works with schizophrenic patients will find this text indispensable.
