The Neurobiology Of Cocaine Addiction

With the use of crack on the rise in American cities, there is more need than ever to understand the biological, environmental, and social factors behind cocaine addiction, as well as the pharmacological properties of cocaine that make it such an addictive drug. The Neurobiology of Cocaine Addiction helps clinicians and researchers analyze research findings and their relevance to the clinical treatment of cocaine dependency. To do this, it looks at the whole spectrum of cocaine use, from trends in cocaine-involved deaths, hospital emergencies, arrests, and treatment admissions to the specific impact the drug has on brain function. The book reports on important findings from positron emission tomography (PET) and a “binge” pattern cocaine administration mode. This will enable you to improve your understanding of how cocaine alters the pleasure/reward system of the brain and creates new instinctual needs that displace the inherent instinctual needs of hunger and sex. By reading The Neurobiology of Cocaine Addiction, you will sharpen your knowledge of the basic actions of cocaine, the factors related to daily cocaine use, the neurobiological basis of addictive diseases, and drug-induced alterations in normal physiology. You will also learn about: the coexistence of cocaine and heroin addiction cocaine’s disruption of the endogenous opioid system QEEG and how it can play a potentially useful role in drug development and planning hypotheses of sensitization in the pathophysiology of cocaine dependence factors that predict daily cocaine use among patients in a methadone maintenance program abnormalities in brain function that persist for up to six months after last cocaine use patterns of cocaine use the importance of prospective data analysis and the limitations of a self-selective study group Clinicians, researchers, psychiatrists, and other professionals in chemical dependency and narcotics rehabilitation will turn the last page of The Neurobiology of Cocaine Addiction with a better understanding of cocaine’s addictive qualities and the characteristics of the individuals who become addicted to it. You will see what headway has been made in research at some of the nation’s top laboratories, but you will also see what remains to be done. Hopefully, you will find where you can make a contribution either at the practical level, the research level, or both.

The Neuroscience of Cocaine: Mechanisms and Treatment explores the complex effects of this drug, addressing the neurobiology behind cocaine use and the psychosocial and behavioral factors that impact cocaine use and abuse. This book provides researchers with an up-to-date understanding of the mechanisms behind cocaine use, and aids them in deriving new pharmacological compounds and therapeutic regimens to treat dependency and withdrawal symptoms. Cocaine is one of the most highly abused illicit drugs worldwide and is frequently associated with other forms of drug addiction and misuse, but researchers are still struggling to understand cocaine’s neuropharmacological profile and the mechanisms of its effects and manifestations at the cognitive level. Cessation of cocaine use can lead to numerous adverse withdrawal conditions, from the cellular and molecular level to the behavioral level of the individual user. Written by worldwide experts in cocaine addiction, this book assists neuroscientists and other addiction researchers in unraveling the many complex facets of cocaine use and abuse. Contains in each chapter an abstract, key facts, mini dictionary of terms, and summary points to aid in understanding Illustrated in full color Provides unique full coverage of all aspects of cocaine and its related pathology Provides researchers with an up-to-date understanding of the mechanisms behind cocaine use, and aids them in deriving new pharmacological compounds and therapeutic regimens to treat dependency and withdrawal symptoms

Cocaine produces its psychoactive & addictive effects primarily by acting on the brain¿s limbic system, a set of interconnected regions that regulate pleasure & motivation. An initial, short-term effect -- a buildup of the neurochemical dopamine -- gives rise to euphoria & a desire to take the drug again. Researchers are seeking to understand how cocaine¿s many longer term effects produce addiction¿s persistent cravings & risk of relapse. This paper focuses on the buildup of the genetic transcription factor DeltaFosB in the limbic system which correlate with addiction-like behaviors in mice & may precipitate very long-lasting changes to nerve cell structure. This is one of the first steps toward an understanding of the transition from cocaine abuse to 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

Representing the latest data from active research groups, The Neurobiology of Cocaine is designed to educate students and inform experts in a rapidly changing field. This volume presents current research regarding the mechanisms of cocaine's action in the brain. Recent developments of cellular, molecular, and brain imaging methods provide new evidence that chemical and molecular substrates underlie cocaine reinforcement, dependence, and withdrawal. This book explores the biological bases of such effects, describing the brain circuits affected by cocaine, neuroendocrine and neurophysiological actions of cocaine, neurochemistry and pharmacology of cocaine, and cocaine effects on signal transduction, gene expression, and protein phosphorylation. This up-to-date text also describes the recently cloned class of neurotransporters affected by cocaine and characterizes their interaction with the drug. These reports focus on the effects of chronic exposure and subsequent withdrawal, which are differentiated from acute cocaine actions. Thus, they provide information on brain mechanisms likely active during long-term use and abuse in humans. Such commonalities are illustrated by a discussion of cocaine action in the human brain as visualized by positron emission tomography. This volume is a must for anyone interested in the mechanisms underlying cocaine 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.

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.
