Cognitive Impairment In Schizophrenia

Provides state-of-the-art information about cognition in schizophrenia with a wide ranging focus on measuring and treating cognitive deficits.

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? A detailed 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.

This volume covers the dramatic developments that have occurred in basic neuroscience and clinical research in cognitive neurology and dementia. It is based on the clinical approach to the patient, and provides essential knowledge that is fundamental to clinical practice.

A practical guide on how to assess and treat schizophrenia and related disorders using cognitive rehabilitation.

Neuropsychiatric diseases, such as schizophrenia, Alzheimer's disease, and etc., represent a serious medical and socioeconomic problems. These diseases are often accompanied by impairments of cognitive function, e.g., abstract thinking, decision-making, attention, and several types of memory. Such deficits significantly disrupt quality of life and daily functioning of patients. Cognitive deficits in neuropsychiatric diseases are associated with alterations of brain morphology and function, and are often resistant to therapeutic interventions. In schizophrenia and related disorders, cognitive deficits are also defined as endophenotypes, i.e. measurable phenotypes linking these disaeses with discrete heritable and reproducible traits. This points to the importance of elucidating these endophenotypes in translational studies. Animal models may not mimic the full spectrum of clinical symptoms, but may act as analogies of particular behaviors or other pathological outcomes. They are useful to search for the etiology of particular psychiatric illnesses and novel therapeutics. Moreover, several behavioral tests to measure cognitive performance in rodents and other species have been implemented. The primary focus of the present topic is to provide up-to-date information on cognitive deficits of neuropsychiatric disorders, such as schizophrenia. This Research Topic also delineates future directions for translational studies aimed at developing novel treatments/interventions of cognitive disturbances.

According to the World Health Organization, schizophrenia affects more than 21 million people worldwide, causing distortions in thinking, perception, emotions, language, sense of self, behavior, and hallucinations. Cognitive and Behavioral Dysfunction in Schizophrenia provides an overview of topics and theories related to cognitive dysfunction in schizophrenia. This book discusses what schizophrenia is and its relationship with the cognitive domains including, but not limited to, learning, working memory, attention, and both deductive and inductive reasoning. This book also reviews theories as to why some individuals develop schizophrenia following cannabis and amphetamine abuse and how these relate to additional cognitive problems. The book further discusses recent topics related to religious delusions in psychotic patients, impact of sleep on psychosis, how urban life increases the likelihood of developing schizophrenia, as well as sexual dysfunction in schizophrenia patients. Unlike other books, Cognitive and Behavioral Dysfunction in Schizophrenia covers many cognitive domains related to the occurrence and development of positive and negative symptoms of schizophrenia. Advanced students and researchers in cognitive and behavioral neuroscience, psychology, psychiatry, and psychotherapy will find it useful for a well-rounded understanding of the subject. Covers neural and behavioral studies addressing the symptomology of schizophrenia Discusses recent studies of the relationship between cognition and schizophrenia symptoms Reviews the development of schizophrenia due to genetic and environmental factors

This volume tries to put current therapy - achievements, shortcomings, remaining medical needs - and emerging new targets into the context of increasing knowledge regarding the genetic and neurodevelopmental contributions to the pathophysiology of schizophrenia. Some of the chapters also deal with respective experimental and clinical methodology, biomarkers, and translational aspects of drug development. The volume concentrates on reviewing the ongoing research attempting to identify novel treatments for the cognitive deficits and negative symptoms of schizophrenia, which are not treated adequately by current antipsychotic medications.

Social Cognition in Psychosis combines current research on phenotypes, neurobiology, and existing evidence on the assessment and treatment of various forms of psychoses. The book presents various treatment options, including assessment approaches, tools and training methods that aid in the rehabilitation of patients with psychotic disorders. Social cognition is a set of psychological processes related to understanding, recognizing, processing and appropriately using social stimuli in one's environment. Individuals with psychotic disorders consistently exhibit impairments in social cognition. As a result, social cognition has been an important target for intervention, with recent efforts trying to enhance early recovery among individuals with psychotic disorders. Provides an overview of social cognition in relation to various forms of psychotic disorders Includes assessment and treatment for social cognition dysfunction in psychoses Discusses the genetics and heritability theory of social cognitive dysfunction in psychosis Defines the neurobiology of social cognitive dysfunctions
