Alcohol Use Disorder and Dementia: A Review

Introduction

In 2020, an estimated 17% of the U.S. population was older than age 65; this proportion is projected to rise to about 23% by 2060.1,2 This prompts an urgent need for identifying potential and modifiable risk factors contributing to health decline.3,4 After tobacco, alcohol is the most misused substance in the United States and abroad.5 Even prior to the coronavirus disease 2019 (COVID...

Sleep-Related Predictors of Risk for Alcohol Use and Related Problems in Adolescents and Young Adults

Introduction

Abundant cross-sectional data indicate that alcohol use and related problems are accompanied by disruptions to sleep and circadian rhythms.1 Alcohol's negative impacts on sleep are well established, especially in adults, and a smaller body of literature also reports alcohol's disruption of circadian rhythms.2-4 Growing evidence supports sleep and circadian factors as influencing...

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...

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’s Negative Emotional Side: The Role of Stress Neurobiology in Alcohol Use Disorder

According to national surveys, more than 85% of U.S. adults have consumed alcohol at some point in their lifetime, and about 70% did so in the last year.1 Most individuals drink responsibly and without adverse effects. However, a substantial proportion of people misuse alcohol.1,2 Drinking patterns associated with alcohol misuse include binge drinking, heavy drinking, and high...

Alcohol-Endocannabinoid Interactions: Implications for Addiction-Related Behavioral Processes

Introduction

Endogenous cannabinoids, or endocannabinoids (eCBs), are bioactive lipid molecules that modulate signaling activity of several physiological processes involved in pain, appetite, energy balance, stress/anxiety, immune signaling, and learning and memory. Although understanding of the eCB system has grown in complexity since its discovery by Raphael Mechoulam, it is now widely known...

Alcohol and the Adolescent Brain: What We’ve Learned and Where the Data Are Taking Us

The past 50 years of research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) have resulted in an accumulation of invaluable data to address the multifaceted problems surrounding underage drinking. Youth use of alcohol remains a pervasive social and public health concern in the United States and a leading cause of disability and mortality during...

The Synaptic Interactions of Alcohol and the Endogenous Cannabinoid System

Introduction

Alcohol use disorder (AUD) is a chronic, relapsing brain disorder, characterized by a compromised ability to control alcohol use despite adverse occupational, social, or health consequences. Results from a 2019 National Survey on Drug Use and Health found that 5% of individuals over age 12 had AUD, affecting 14.5 million people in the United States. Alcohol and cannabis products are...

AUD Risk, Diagnoses, and Course in a Prospective Study Across Two Generations: Implications for Prevention

Introduction

A large proportion of the population consume alcoholic beverages at some time in their lives. For most people, alcohol consumption is low to moderate and is not associated with harmful physiological, psychological, or social outcomes. However, for a substantial number of individuals, alcohol consumption increases over time; leads to the development of tolerance and alcohol-related...
