Book Description
Excessive risky decision-making is common in multiple psychiatric disorders, including substance abuse disorder. The risky decision-making task (RDT) models addiction-relevant risk-taking in rats by measuring preference between a small reward and large reward associated with systematically increasing risk of shock. This Thesis examined the relationship between risk-taking in the RDT and multiple cognitive and neurobiological addiction-relevant phenotypes. Risk-taking was associated with elevated impulsive action, but not impulsive choice or habit formation. Furthermore, risk-taking predicted locomotor sensitivity to first-time nicotine exposure and resilience to nicotine-evoked anxiety. Finally, risk-taking was associated with elevated phasic dopamine release and sensitivity to the dopamine transporter inhibitor nomifensine in the nucleus accumbens. Collectively, these data demonstrate that risk preference in the RDT predicts a cluster of traits associated with substance abuse, and may have utility for identification of neurobiological and genetic biomarkers that engender addiction vulnerability.

Book Description
This book provides an overview of the state of the art in research on and treatment of gambling disorder. As a behavioral addiction, gambling disorder is of increasing relevance to the field of mental health. Research conducted in the last decade has yielded valuable new insights into the characteristics and etiology of gambling disorder, as well as effective treatment strategies. The different chapters of this book present detailed information on the general concept of addiction as applied to gambling, the clinical characteristics, epidemiology and comorbidities of gambling disorder, as well as typical cognitive distortions found in patients with gambling disorder. In addition, the book includes chapters discussing animal models and the genetic and neurobiological underpinnings of the disorder. Further, it is examining treatment options including pharmacological and psychological intervention methods, as well as innovative new treatment approaches. The book also discusses relevant similarities to and differences with substance-related disorders and other behavioral addictions. Lastly, it examines gambling behavior from a cultural perspective, considers possible prevention strategies and outlines future perspectives in the field.

Book Description
Traditionally, impulsive and compulsive behaviors have been categorized as fundamentally distinct. However, patients often exhibit both of these behaviors. This common comorbidity has sparked renewed interest in the factors contributing to the disorders in which these behaviors are prominent. Impulsivity and Compulsivity applies a provocative spectrum model to this psychopathology. The spectrum model is consistent with a dimensional model for psychopathology and considers the dynamic interaction of biopsychosocial forces in the development of impulsive and compulsive disorders. In this important work on impulsive/compulsive psychopathology, leading researchers and clinicians share their expertise on the phenomenological, biological, psychodynamic, and treatment aspects of these disorders. Differential diagnosis, comorbidity of the impulsive-compulsive spectrum of disorders, and assessment by the seven-factor model of temperament and character are discussed. Chapters are also dedicated to the antianxiety function of impulsivity and compulsivity, defense mechanisms in impulsive disorders versus obsessive-compulsive disorders, and the unique aspects of psychotherapy with impulsive and compulsive patients. Clinical researchers and clinicians will be enlightened by this exceptional work. The information provided is supplemented with clinical vignettes, and the final chapter provides a synthetic summary that offers a unified, dynamic approach to impulsive and compulsive behavior.

Book Description
This volume covers the current status of research in the neurobiology of motivated behaviors in humans and other animals in healthy condition. This includes consideration of the psychological processes that drive motivated behavior and the anatomical, electrophysiological and neurochemical mechanisms which drive these processes and regulate behavioural output. The volume also includes chapters on pathological disturbances in motivation including apathy, or motivational deficit as well as addictions, the pathological misdirection of motivated behavior. As with the chapters on healthy motivational processes, the chapters on disease provide a comprehensive up to date review of the neurobiological abnormalities that underlie motivation, as determined by studies of patient populations as well as animal models of disease. The book closes with a section on recent developments in treatments for motivational disorders.

Book Description
Research increasingly suggests that addiction has a genetic and neurobiological basis, but efforts to translate research into effective clinical treatments and social policy needs to be informed by careful ethical analyses of the personal and social implications. Scientists and policy makers alike must consider possible unintended negative consequences of neuroscience research so that the promise of reducing the burden and incidence of addiction can be fully realized and new advances translated into clinically meaningful and effective treatments. This volume brings together leading addiction researchers and practitioners with neuroethicists and social scientists to specifically discuss the ethical, philosophical, legal and social implications of neuroscience research of addiction, as well as its translation into effective, economical and appropriate policy and treatments. Chapters explore the history of ideas about addiction, the neuroscience of drug use and addiction, prevention and treatment of addiction, the moral implications of addiction neuroscience, legal issues and human rights, research ethics, and public policy. Features outstanding and truly international scholarship, with chapters written by leading experts in neuroscience, addiction medicine, psychology and more Informs psychologists of related research in neuroscience and vice versa, giving researchers easy one-stop access to knowledge outside their area of specialty

Book Description
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. This comprehensive and accessible volume will have widespread relevanceâ€"to policymakers, researchers, research administrators, foundation decisionmakers, healthcare professionals, faculty and students, and concerned individuals.

Book Description
All across the United States, individuals, families, communities, and health care systems are struggling to cope with substance use, misuse, and substance use disorders. Substance misuse and substance use disorders have devastating effects, disrupt the future plans of too many young people, and all too often, end lives prematurely and tragically. Substance misuse is a major public health challenge and a priority for our nation to address. The effects of substance use are cumulative and costly for our society, placing burdens on workplaces, the health care system, families, states, and communities. The Report discusses opportunities to bring substance use disorder treatment and mainstream health care systems into alignment so that they can address a person's overall health, rather than a substance misuse or a physical health condition alone or in isolation. It also provides suggestions and recommendations for action that everyone-individuals, families, community leaders, law enforcement, health care professionals, policymakers, and researchers-can take to prevent substance misuse and reduce its consequences.
