Given the pervasiveness of alcohol use disorders (AUDs) in the United States, Dr. Mark Willenbring says, “we need to be intervening at a much earlier stage and providing treatment to a much broader range of people then we currently do.” Dr. Willenbring, director of the National Institute on Alcohol Abuse and Alcoholism's Division of Treatment and Recovery Research, joins host Dr. Larry Kaskel to talk about new information from epidemiologic research on the prevalence and progression of heavy drinking and alcohol use disorders. In addition, Dr. Willenbring discusses the subtypes of alcohol dependence, and the nature of AUDs, in the context of DSM revisions.
