Neurobiology Of Addiction

Neurobiology of Addiction is conceived as a current survey and synthesis of the most important findings in our understanding of the neurobiological mechanisms of addiction over the past 50 years. The book includes a scholarly introduction, thorough descriptions of animal models of addiction, and separate chapters on the neurobiological mechanisms of addiction for psychostimulants, opioids, alcohol, nicotine and cannabinoids. Key information is provided about the history, sources, and pharmacokinetics and psychopathology of addiction of each drug class, as well as the behavioral and neurobiological mechanism of action for each drug class at the molecular, cellular and neurocircuitry level of analysis. A chapter on neuroimaging and drug addiction provides a synthesis of exciting new data from neuroimaging in human addicts — a unique perspective unavailable from animal studies. The final chapters explore theories of addiction at the neurobiological and neuroadaptational level both from a historical and integrative perspective. The book incorporates diverse finding with an emphasis on integration and synthesis rather than discrepancies or differences in the literature. · Presents a unique perspective on addiction that emphasizes molecular, cellular and neurocircuitry changes in the transition to addiction · Synthesizes diverse findings on the neurobiology of addiction to provide a heuristic framework for future work · Features extensive documentation through numerous original figures and tables that that will be useful for understanding and teaching

Runner-up winner of the Hamilton Book Author Award, this book is a comprehensive overview of the neurobiology behind addictions. Neuroscience is clarifying the causes of compulsive alcohol and drug use––while also shedding light on what addiction is, what it is not, and how it can best be treated––in exciting and innovative ways. Current neurobiological research complements and enhances the approaches to addiction traditionally taken in social work and psychology. However, this important research is generally not presented in a forthright, jargon-free way that clearly illustrates its relevance to addiction professionals. The Science of Addiction presents a comprehensive overview of the roles that brain function and genetics play in addiction. It explains in an easy-to-understand way changes in the terminology and characterization of addiction that are emerging based upon new neurobiological research. The author goes on to describe the neuroanatomy and function of brain reward sites, and the genetics of alcohol and other drug dependence. Chapters on the basic pharmacology of stimulants and depressants, alcohol, and other drugs illustrate the specific and unique ways in which the brain and the central nervous system interact with, and are affected by, each of these substances Erickson discusses current and emerging treatments for chemical dependence, and how neuroscience helps us understand the way they work. The intent is to encourage an understanding of the body-mind connection. The busy clinical practitioner will find the chapter on how to read and interpret new research findings on the neurobiological basis of addiction useful and illuminating. This book will help the almost 21.6 million Americans, and millions more worldwide, who abuse or are dependent on drugs by teaching their caregivers (or them) about the latest addiction science research. It is also intended to help addiction professionals understand the foundations and applications of neuroscience, so that they will be able to better empathize with their patients and apply the science to principles of treatment.

Combines classic theories with current neuroscientific studies to explain the addiction cycle, focusing on neuroimaging studies and applications.

A NEW YORK TIMES BESTSELLER From a renowned behavioral neuroscientist and recovering addict, a rare page-turning work of science that draws on personal insights to reveal how drugs work, the dangerous hold they can take on the brain, and the surprising way to combat today's epidemic of addiction. Judith Grisel was a daily drug user and college dropout when she began to consider that her addiction might have a cure, one that she herself could perhaps discover by studying the brain. Now, after twenty-five years as a neuroscientist, she shares what she and other scientists have learned about addiction, enriched by captivating glimpses of her personal journey. In Never Enough, Grisel reveals the unfortunate bottom line of all regular drug use: there is no such thing as a free lunch. All drugs act on the brain in a way that diminishes their enjoyable effects and creates unpleasant ones with repeated use. Yet they have their appeal, and Grisel draws on anecdotes both comic and tragic from her own days of using as she limns the science behind the love of various drugs, from marijuana to alcohol, opiates to psychedelics, speed to spice. With more than one in five people over the age of fourteen addicted, drug abuse has been called the most formidable health problem worldwide, and Grisel delves with compassion into the science of this scourge. She points to what is different about the brains of addicts even before they first pick up a drink or drug, highlights the changes that take place in the brain and behavior as a result of chronic using, and shares the surprising hidden gifts of personality that addiction can expose. She describes what drove her to addiction, what helped her recover, and her belief that a “cure” for addiction will not be found in our individual brains but in the way we interact with our communities. Set apart by its color, candor, and bell-clear writing, Never Enough is a revelatory look at the roles drugs play in all of our lives and offers crucial new insight into how we can solve the epidemic of 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.

This volume provides a thorough and up-to-date synthesis of the expansive and highly influential literature from the last 30 years by bringing together contributions from leading authorities in the field, with emphasis placed on the most commonly investigated drugs of abuse. Emphasises the most commonly investigated drugs of abuse, including alcohol, cocaine, nicotine, and opiates Brings together the work of the leading authorities in all major areas of the field Provides novel coverage of cutting-edge methods for using cognitive neuroscience to advance the treatment of addiction, including real-time neurofeedback and brain stimulation methods Includes new material on emerging themes and future directions in the use of cognitive neuroscience to advance addiction science

A current survey and synthesis of the most important findings in our understanding of the neurobiological mechanisms of addiction is detailed in our Neurobiology of Addiction series, each volume addressing a specific area of addiction. Alcohol, Volume 3 in the series, explores the molecular, cellular, and neurocircuitry systems in the brain responsible for alcohol addiction using the heuristic three-stage cycle framework of binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation. Outlines the history and behavioral mechanism of action of alcohol relevant to the neurobiology of alcohol addiction Includes neurocircuitry, cellular, and molecular neurobiological mechanisms of alcohol addiction in each stage of the addiction cycle Explores evolving areas of research associated with all three stages of the alcohol addiction cycle, including neurobiological studies of neurodevelopmental effects of early exposure to alcohol, sleep disturbances caused by alcohol, pain interactions with alcohol, sex differences in the response to alcohol, and epigenetic/genetic interactions with alcohol

Neurobiology of Addiction highlights some of the most promising research areas of the rapidly expanding field of addiction. It will be useful as a practical tool for clinicians, research investigators, and trainees-both in addiction and in other illnesses with overlapping mechanisms-as well as an informative resource for non-technical readers who are interested in addiction or mental health policy. The editors have combined their areas of expertise to provide a unique perspective into the prevention and treatment of addictive disorders. Their approach addresses addiction in the broader context of behavioral processes and survival-related adaptations, focusing on its neurobiological precursors and drawing parallels between addictions and other recurrent or progressive psychiatric disorders. The book also emphasizes resilience, clinical contexts of addictive behavior, and treatment strategies that target its underlying neurobiological mechanisms.
