Circadian Genes, the Stress Axis, and Alcoholism

Alcohol abuse and dependence are estimated to affect 1 in 8 adults in the United States and several hundred million people worldwide (Grant et al. 2004). To define at-risk populations and develop better treatments, it is important to further identify the genetic and environmental factors that contribute to alcohol addiction. Recent evidence suggests that the body’s internal system that helps...

Discovering Genes Involved in Alcohol Dependence and Other Alcohol Responses

A host of biological (i.e., genetic) and environmental factors interact throughout the addictive process to influence alcohol use and abuse. These processes are accompanied by a number of behavioral and neural events that include, but are not limited to, changes in the motivational effects of ethanol (both rewarding and aversive), tolerance to some effects of ethanol, and withdrawal when ethanol...

Genetics Glossary

Agonist: An agent that mimics the actions or effects of another agent at a receptor (e.g., a drug that mimics the effects of a neurotransmitter).

Allele: One of two or more forms of a gene that reside at the same position on a pair of chromosomes; different alleles of a gene may serve the same function (e.g., code for an enzyme that breaks down alcohol) but may result in proteins with different...

Genetic and Genomic Web Resources for Research on Alcohol Use and Abuse

There are two major ways of publishing scientific data and results: (1) the standard peer-reviewed paper, which dates back to volume 1 of the Philosophical Transactions of the Royal Society in 1665; and (2) online distribution of data, resources, and software using the Internet that dates back a mere 21 years to the first Web site at the European Organization for Nuclear Research (CERN)...

Alcohol Use Disorder: The Role of Medication in Recovery

Introduction

It is estimated that nearly 14.6 million Americans currently meet the diagnostic criteria for alcohol use disorder (AUD)1 included in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5),2 and approximately 88,000 die from alcohol-related causes in the United States each year.3 An older term, “alcohol dependence,” is equivalent to the DSM-5 criteria for AUD...

NIAAA 50th Anniversary Festschrift: From the Editor

A Look Back

NIAAA’s 50th anniversary is truly a highlight in the history of public health. More than 5 decades ago, a group of researchers, advocates, and elected officials made a farsighted decision when they pushed for the creation of a federal institution dedicated to research that improves the lives of millions of Americans and their families devastated by alcohol misuse. As a result, on...

Low to Moderate Prenatal Alcohol Exposure and Neurodevelopmental Outcomes: A Narrative Review and Methodological Considerations

Introduction

Prenatal alcohol exposure (PAE) is a necessary cause of fetal alcohol spectrum disorders (FASD), a group of alcohol-related conditions characterized by neurodevelopmental problems. Although PAE is associated with many adverse physical, neurodevelopmental, and social outcomes, the most commonly studied are neurodevelopmental—primarily behavioral and cognitive—outcomes. Associations...

Reducing Prenatal Alcohol Exposure and the Incidence of FASD: Is the Past Prologue?

Introduction

Prenatal alcohol exposure (PAE) is linked to miscarriage, stillbirth, preterm birth, sudden infant death syndrome, and fetal alcohol spectrum disorders (FASD).1 Although PAE is the sole necessary cause of FASD, the etiology of this leading preventable cause of disability is multifaceted and complex, including lifestyle, maternal, sociodemographic, social, gestational, and genetic...

Identifying Prenatal Alcohol Exposure and Children Affected by It: A Review of Biomarkers and Screening Tools

Introduction

Although the awareness of the negative impact of prenatal alcohol exposure (PAE) was already alluded to in ancient writings1 and the impact of ethanol embryopathy in animal models was studied as early as 1910,2 the conceptualization of a syndrome associated with PAE was not recognized within modern medicine until the mid-20th century.3,4 The syndrome or disorder was not uniformly...

Alcohol and Skeletal Muscle in Health and Disease

Introduction

Alcohol misuse is the most common form of substance misuse and is associated with liver, cardiovascular, and metabolic diseases as well as with infections and cancers.1 Although an estimated 20% to 25% of people who drink heavily develop alcohol-related liver disease,2 40% to 60% of people with alcohol misuse have alcohol-related myopathy.3 Evidence that alcohol use leads to skeletal...
