Cognitive Clinical And Neural Aspects Of Drug Addiction

Cognitive, Clinical, and Neural Aspects of Drug Addiction focuses on the theories that cause drug addiction, including avoidance behavior, self-medication, reward sensitization, behavioral inhibition and impulsivity. Dr. Moustafa takes this book one-step further by reviewing the psychological causes of relapse, including the role stress, anxiety and depression play. By examining both the causes of drug addiction and relapse, this book will help clinicians create individualized treatment options for their patients suffering from drug addiction. Understanding the development of individual drug addictions are often difficult to understand and, more often, difficult to treat. The most successful treatments begin with studying why individuals become addicted to drugs and how to change their thinking and behavior.

In Neuropsychological Aspects of Substance Use Disorders, internationally recognized experts provide clinicians with a translational overview of basic research and treatment findings regarding addictions, neuropsychological and neurological sequalae of the most common substances of abuse.

Neuroimaging in Addiction presents an up-to-date, comprehensive review of the functional and structural imaging human studies that have greatly advanced our understanding of this complex disorder. Approaching addiction from a conceptual rather than a substance-specific perspective, this book integrates broad neuropsychological constructs that consider addiction as a neuroplastic process with genetic, developmental, and substance-induced contributions. The internationally recognized contributors to this volume are leaders in clinical imaging with expertise that spans the addiction spectrum. Following a general introduction, an overview of neural circuitry and modern non-invasive imaging techniques provides the framework for subsequent chapters on reward salience, craving, stress, impulsivity and cognition. Additional topics include the use of neuroimaging for the assessment of acute drug effects, drug-induced neurotoxicity, non-substance addictive behaviors, and the application of imaging genetics to identify unique intermediate phenotypes. The book concludes with an exploration of the future promise for functional imaging as guide to the diagnosis and treatment of addictive disorders. Scientists and clinicians will find the material in this volume invaluable in their work towards understanding the addicted brain, with the overall goal of improved prevention and treatment outcomes for patients. Features a Foreword by Edythe London, Director of the Center for Addictive Behaviors, University of California at Los Angeles.

Drug abuse persists as one of the most costly and contentious problems on the nation's agenda. Pathways of Addiction meets the need for a clear and thoughtful national research agenda that will yield the greatest benefit from today's limited resources. The committee makes its recommendations within the public health framework and incorporates diverse fields of inquiry and a range of policy positions. It examines both the demand and supply aspects of drug abuse. Pathways of Addiction offers a fact-filled, highly readable examination of drug abuse issues in the United States, describing findings and outlining research needs in the areas of behavioral and neurobiological foundations of drug abuse. The book covers the epidemiology and etiology of drug abuse and discusses several of its most troubling health and social consequences, including HIV, violence, and harm to children. Pathways of Addiction looks at the efficacy of different prevention interventions and the many advances that have been made in treatment research in the past 20 years. The book also examines drug treatment in the criminal justice setting and the effectiveness of drug treatment under managed care. The committee advocates systematic study of the laws by which the nation attempts to control drug use and identifies the research questions most germane to public policy. Pathways of Addiction provides a strategic outline for wise investment of the nation's research resources in drug abuse.

In the past two decades, there have been astonishing advances in our understanding of the neurobiological basis and nature of drug addiction. We now know the initial molecular sites of action, at identified receptors, of virtually all of the major drugs of abuse including cocaine, heroin, and amphetamine, as well as legal drugs such as nicotine and alcohol. We also understand the main components of a 'reward system' and its connections to major brain regions involved in motivation and emotion, such as the amygdala, hippocampus, and prefrontal cortex. The Neurobiology of Addiction describes the latest advances in our understanding of addiction. It brings together world class researchers to debate the nature and extent of addiction, as well as its causes, consequences, and treatment. The focus of the book is on the brain processes underlying addiction, in terms of neural systems, neurochemical basis, and molecular changes. Several types of addiction are discussed ranging from illicit drugs - cocaine, amphetamine, and heroin to legal drugs - alcohol and nicotine. In addition, it explores increasingly common behavioural addictions such as gambling and obesity. Included are chapters on vulnerability to addiction, genetic factors, opponent motivational processes, animal models, relapse, cognitive deficits associated with drug abuse, new pharmacological treatments, and current controversies concerning different neuropsychological theories of addiction. Throughout, it reports on cutting edge research using brain imaging, and state of the art molecular methodology. The book will make fascinating reading for students and teachers in the field of neuroscience, pharmacology and psychology, as well as experts in the field.

Drug addiction may be viewed as a form of learning during which strong associations linking actions to drug-seeking are expressed as persistent stimulus–response habits, thereby maintaining a vulnerability to relapse. Disrupting cue–drug memory could be an efficient strategy to reduce the strength of cues in motivating drug-taking behavior. Upon reactivation, these memories undergo a reconsolidation process that can be blocked pharmacologically, providing an opportunity to prevent the powerful control of drug cues on behavior. This conceptually elegant approach still calls for more experimental data. However, an increasing body of evidence suggests that drug taking not only accelerates habit forming, but has long-lasting effects on interactions between memory systems eventually leading to a functional imbalance. The dorsal part of the striatum plays a critical role in habit/procedural learning, whereas the hippocampal memory system encodes relationships between events and their later flexible use. Both humans and rodents studies support the view that the hippocampus and the dorsal striatum interact in either a cooperative or competitive manner during learning, the prefrontal cortex being involved in the selection of an appropriate learning strategy. Chronic drug consumption biases normal interactions between these memory systems. For instance, drug-experienced rodents tend to use preferentially striatum-dependent learning strategies in navigational tasks. These persistent effects seem to occur at cellular, neurophysiological and behavioral levels to promote specific, striatal-dependent forms of learning, to the detriment of spatial/declarative, hippocampal-dependent and more flexible types of memory. Whether cue sensitive and response learners, in contrast to spatial learners, could be prone to drug addiction is an intriguing hypothesis which clearly deserves to be further explored. A loss of flexibility may be uncovered also by imposing changing rules on the subject, such as requiring an attentional shift between different perceptual features of a complex stimulus, as in the attentional set shifting task which was recently adapted to rodents. Working memory is at risk during transition phases, although it remains to be determined whether withdrawal-induced alterations are observed also during protracted abstinence. Drug-induced cognitive biases thus lead to cognitive rigidity which could play a critical, yet overlooked role in different phases of addiction (acquisition, extinction/withdrawal and relapse). They are also likely to preclude the clinical efficiency of treatments. Therefore, the aim of this research topic is to provide an overview of the current work investigating the long-term impact of drug use on learning and memory processes, how multiple memory systems modulate drug-seeking behavior, as well as how drug-induced cognitive biases could contribute to the persistence of addictive behaviors.
