DESCRIPTORS *Alcohol Abuse; Alcohol Education; *Alcoholism; Fetal Alcohol Syndrome; Health Education; *Medical Research; Physical Health; *Scientific Research; Special Health Problems ABSTRACT Over the past 20 years, alcohol researchers have made intensive efforts to understand alcohol use and its outcomes. To date, researchers have made much progress toward understanding the causes and consequences of alcoholism and its related problems. This publication attempts to convey the great spirit and promise of alcohol research. Established findings that serve as foundations for future research are presented, and compelling areas for the coming decade that promise to advance understanding of the nature of alcoholism and promote efforts to prevent and treat the disease are highlighted. Extensive illustrations and photographs supplement the text. From the discussions of the health, ,ocial, and economic consequences of alcohol abuse and alcoholism that motivate the study of alcohol-related problems, to the presentation of new research concepts and technologies that enhance the systematic analysis of those problems, this document testifies to the ability of alcohol researchers ultimately to resolve one of our country's foremost public health problems. Chapters are:(1) Alcohol Abuse and Alcoholism;(2) Alcohol and the Brain;(3) Genetics and Environment; (4)Why DoPeopleDrink?;(5) The Medical Consequences of Alcoholism; (6)FetalAlcoholSyndrome; (7) Prevention and Treatment. An additionalchaptercontains information on developing new medications for alcoholism.
