Biology, Genetics, and Environment: Underlying Factors Influencing Alcohol Metabolism

Epidemiological studies have demonstrated that drinking patterns and the prevalence of alcohol-related adverse consequences, including alcohol use disorder (AUD), differ substantially among racial/ethnic groups in the United States. For example, analyses comparing drinking patterns and their consequences among Whites, Blacks, Asians, and Hispanics found the following: Whites have the highest risk...

Alcohol Use Disorder and Alcohol-Associated Liver Disease

Introduction

Alcohol use disorder (AUD) is prevalent worldwide, and the burden of heavy alcohol consumption has been increasing over time. An important complication of prolonged, heavy alcohol use is alcohol-associated liver disease (ALD), which can progress from liver steatosis to fibrosis and cirrhosis and frequently involves alcohol-associated hepatitis. In particular, cirrhosis—the most...

Alcohol Use Disorder and Depressive Disorders

Alcohol use disorder (AUD) and depressive disorders are among the most prevalent psychiatric disorders and co-occur more often than expected by chance. The aim of this review is to characterize the prevalence, course, and treatment of co-occurring AUD and depressive disorders. Studies have indicated that the co-occurrence of AUD and depressive disorders is associated with greater severity and...

What Is Recovery?

Alcohol use disorder (AUD) is among the most prevalent psychiatric disorders and is associated with enormous public health costs. Although AUD and other addictive behaviors have been described as chronic relapsing conditions, most individuals who develop AUD will eventually recover. This narrative review provides an overview of definitions of recovery, with a focus on recovery from AUD. The...

The Impact of Gene–Environment Interaction on Alcohol Use Disorders

This article explores interactions between genetic and environmental effects on alcohol use disorders (AUDs). Two contrasting ideas define what it means to have genes and environment interact. The first approach—the one that this article will focus on—is a statistical perspective. This approach is based on statistical models in which genetic and environmental factors are sometimes measured...

Drinking Patterns and Their Definitions

The number of drinks a person consumes and the rate at which he or she consumes them influence how much alcohol enters the brain and how impaired that person becomes. Many people are surprised to learn what counts as a drink. The amount of liquid in one’s glass, can, or bottle does not necessarily match up to how much alcohol is in the drink. To facilitate research and clinical care and to help...

The Role of the Family in Alcohol Use Disorder Recovery for Adults

Introduction

It is almost axiomatic that alcohol use disorder (AUD) and the family are inextricably bound. AUD harms individual family members and the functioning of the family as a whole, and family members’ actions may exacerbate problematic drinking. Conversely, families play a key role in recovery from AUD, and recovery has a positive impact on family members and family functioning...

Identifying Gene Networks Underlying the Neurobiology of Ethanol and Alcoholism

The multiple genetic, environmental, and behavioral factors that play a role in the development of alcohol use disorders (AUDs) make it difficult to identify individual genes linked to these disorders. Nevertheless, some genetic risk factors (i.e., specific variants) associated with AUDs have been identified within many genes, some of which code for proteins involved in known biological pathways...

Alcohol Use Disorder and Schizophrenia or Schizoaffective Disorder

Introduction

Schizophrenia and schizoaffective disorder are heterogeneous psychotic disorders that often cause significant disability, with symptoms that include delusions, hallucinations, disorganization, and cognitive impairment.1 In schizoaffective disorder, the psychotic symptoms are present, along with mood episodes of depression or mania.2 People with these schizophrenia spectrum disorders...

Patterns of Cannabis and Alcohol Co-Use: Substitution Versus Complementary Effects

Introduction

Use of alcohol and related problems cause significant global and individual health-related harms, and alcohol use is currently the third-leading cause of preventable death in the United States.1,2 Alcohol and cannabis are among the most commonly used psychoactive substances in the United States.3 Although concurrent use of alcohol and cannabis (i.e., co-use: defined as using both...
