Genetic Influences On Addiction

A comprehensive review of research examining intermediary mechanisms to understand the link between genetic variation and addiction liability. Although there is scientific consensus that genetic factors play a substantial role in an individual's vulnerability to drug or alcohol addiction, specific genetic variables linked to risk or resilience remain elusive. Understanding how genetic factors contribute to addiction may require focusing on intermediary mechanisms, or intermediate phenotypes, that connect genetic variation and risk for addiction. This book offers a comprehensive review of this mechanistic-centered approach and the most promising intermediate phenotypes identified in empirical research. The contributors first consider the most established findings in the field, including variability in drug metabolism, brain electrophysiological profiles, and subjective reactions to direct drug effects; they go on to review highly promising areas such as expectancies, attentional processing, and behavioral economic variables; and finally, they investigate more exploratory approaches, including the differential susceptibility hypothesis and epigenetic modifications. Taken together, the chapters offer a macro-level testing of the hypothesis that these alternative, mechanistic phenotypes can advance the understanding of genetic influences on addiction. The book will be of interest to researchers and practitioners in a range of disciplines, including behavioral genetics, psychology, pharmacology, neuroscience, and sociology.

This volume provides an in-depth look at the genetic influences that contribute to the development of alcoholism. Part I: Epidemiologic Studies contains five chapters that examine the various approaches employed in the study of the genetics of alcoholism. It provides a historical perspectiveand details all the essentials of this subject. Part II: Selective Breeding Studies highlights the results of research involving the selective breeding of rodents. This type of research has produced homogenous strains exhibiting specific behavioral responses considered significant in thedevelopment and maintenance of alcohol dependence. The studies presented in Part III: Phenotypic Studies investigate and analyze phenotypic markers that serve as correlates to the genotypic determinants of alcoholism. Through its broad scope, this volume provides for the first time a panoramic viewof the knowledge available on the hereditary influences of alcoholism.

Produced as a partnership between the American Psychiatric Association and the National Institute of Mental Health, the National Institute on Alcohol Abuse and Alcoholism and the National Institute on Drug Abuse, this thought-provoking collection of white papers: Examines nomenclature issues. Reviews genetic, brain imaging, postmortem, and animal model research and includes strategic insights for a new research agenda Outlines recent progress in developmental neuroscience, genetics, psychology, psychopathology, and epidemiology, focusing on the turbulent first two decades of life. Suggests a research agenda for personality disorders that uses a dimensional rather than the current categorical approach to diagnosis. Proposes a research agenda to evaluate the clinical utility and validity of adding relational disorders to DSM-IV. Reevaluates the relationship between mental disorders and disability, proposing that diagnosis and disability be uncoupled. Examines the importance of culture in psychopathology and the main cultural variables at play in the diagnostic process.

How tiny variations in our personal DNA can determine how we look, how we behave, how we get sick, and how we get well. News stories report almost daily on the remarkable progress scientists are making in unraveling the genetic basis of disease and behavior. Meanwhile, new technologies are rapidly reducing the cost of reading someone's personal DNA (all six billion letters of it). Within the next ten years, hospitals may present parents with their newborn's complete DNA code along with her footprints and APGAR score. In Genetic Twists of Fate, distinguished geneticists Stanley Fields and Mark Johnston help us make sense of the genetic revolution that is upon us. Fields and Johnston tell real life stories that hinge on the inheritance of one tiny change rather than another in an individual's DNA: a mother wrongly accused of poisoning her young son when the true killer was a genetic disorder; the screen siren who could no longer remember her lines because of Alzheimer's disease; and the president who was treated with rat poison to prevent another heart attack. In an engaging and accessible style, Fields and Johnston explain what our personal DNA code is, how a few differences in its long list of DNA letters makes each of us unique, and how that code influences our appearance, our behavior, and our risk for such common diseases as diabetes or cancer.

As the population of older Americans grows, it is becoming more racially and ethnically diverse. Differences in health by racial and ethnic status could be increasingly consequential for health policy and programs. Such differences are not simply a matter of education or ability to pay for health care. For instance, Asian Americans and Hispanics appear to be in better health, on a number of indicators, than White Americans, despite, on average, lower socioeconomic status. The reasons are complex, including possible roles for such factors as selective migration, risk behaviors, exposure to various stressors, patient attitudes, and geographic variation in health care. This volume, produced by a multidisciplinary panel, considers such possible explanations for racial and ethnic health differentials within an integrated framework. It provides a concise summary of available research and lays out a research agenda to address the many uncertainties in current knowledge. It recommends, for instance, looking at health differentials across the life course and deciphering the links between factors presumably producing differentials and biopsychosocial mechanisms that lead to impaired health.
