Since its founding, the NIAAA has led increasingly effective efforts to define alcohol abuse as a medical problem and to address the problem by applying research-based findings. In 1971, it issued its first special report to the US Congress on alcohol and health. Department of Agriculture, the dietary guidelines provide recommendations on what the average American should eat and drink to promote health and help prevent chronic disease. 2018—CRAN, based on the need to understand how substance use and other experiences during adolescence influence development, established the Adolescent Behavioral and Cognitive (ABCD) Study, a large scale, long-term, longitudinal study.
From the Director
- Once it was assumed that most alcohol-related problems result from heavy drinking by alcoholics, who were therefore viewed as the appropriate target for preventive and treatment efforts.
- For a typical adult, this pattern corresponds to consuming five or more drinks (male), or four or more drinks (female), in about two hours.1 In the United States, a “standard drink” is defined as any beverage containing 0.6 fl oz or 14 grams of pure alcohol.
- This article reviews some of the major advances in alcohol research in which NIAAA has participated and looks forward to the achievements of the future.
- An essential impetus to the development of alcoholism research was the acceptance of alcoholism as a medical disorder.
Alcohol interferes with its absorption; deficiency can trigger Wernicke‑Korsakoff syndrome. Sleep, mood and attention improve within days‑weeks; white‑matter repair occurs over 3‑6 months; many cognitive functions continue to improve up to 1‑2 years, though severe, long‑standing damage may persist. Therapy, medication, or both can stabilize the waves so you don’t need a drink to feel okay. Cardio boosts BDNF (a brain growth factor), while resistance training supports metabolic health and mood.
Moderate drinking
More than half of those surveyed said drinking is bad for your health, up from 45% in 2024. In the United States, the Diagnostic and Statistical Manual of Mental Disorders (DSM) is the most common diagnostic guide for substance use disorders, whereas most countries use the International Classification of Diseases (ICD) for diagnostic (and other) purposes. The two manuals use similar but not identical nomenclature to classify alcohol problems.
As basic research expands our knowledge base, a consistent pattern appears to be emerging that ultimately will help guide improved prevention and treatment efforts. NIAAA-sponsored researchers have conducted studies using experimental animals to answer many important questions about FAS. One of the first issues that researchers addressed was whether alcohol itself is responsible for FAS. Alcoholic women frequently smoke tobacco, have poor health, and are malnourished, any of which factors can cause birth defects. Two different laboratories reported that alcohol administration to pregnant mice resulted in birth defects similar to those of FAS (Chernoff 1977; Randall et al. 1977), suggesting that alcohol itself caused the defects.
Alcohol and the Human Body
AUD is a medical condition characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. It encompasses the conditions that some people refer to as alcohol abuse, alcohol dependence, alcohol addiction, and the colloquial term, alcoholism. Lasting changes in the brain caused by alcohol misuse perpetuate AUD and make individuals vulnerable to relapse. In 2006, the NIAAA released a five-year plan, the NIAAA Strategic Plan for Research. It employs a new framework, labeled a lifespan perspective, for organizing future research.
NIH Clinical Center (CC)
Nevertheless, the disease concept has sharpened the focus of alcohol research and has helped remove the stigma from a chronic disorder that is no more inherently immoral than diabetes or heart disease. In 1974, the NIAAA became an independent institute within the NIH’s Alcohol, Drug Abuse, and Mental Health Administration. Its research responsibilities were expanded at this time and again in 1976. In 1977, the NIAAA organized the first international research conference on fetal alcohol spectrum disorders.
- With ongoing support for studies and outreach, the NIAAA remains committed to fostering a better understanding of alcohol-related problems and promoting healthier communities.
- In 2020, NIAAA published significant updates to the CollegeAIM website, updating resources and scientific evidence.
- This is one of the starkest examples of brain damage from alcohol—and a reminder that nutrition and timely treatment matter.
- Alcoholism is characterized by abnormal alcohol-seeking behavior and impaired control over drinking.
- NIAAA helped launch a website to share funding opportunities and research resources readily with the public.
- 2013—NIAAA helped establish and participated in the NIH partnership, Collaborative Research on Addiction at NIH (CRAN).
What Are Other Harms of Alcohol Misuse?
Supervised detox or a careful taper can prevent complications and make you far more comfortable. Thiamine protects vulnerable brain regions by supporting energy pathways. If there’s any concern about deficiency—or if you’re a heavy drinker—clinicians often start thiamine early. Poor oxygenation at night plus neuroinflammation can accelerate cognitive problems. If you snore loudly or feel wiped out despite sleep, getting evaluated can protect your brain as much as cutting back on alcohol.
The course, produced alcohol’s effects on health national institute on alcohol abuse and alcoholism niaaa jointly with Medscape, shows providers how to conduct fast, evidence-based alcohol screening and brief intervention for patients ages 9–18. Since its launch in August, more than 5,000 health care professionals have earned credit for the course. Alcoholism treatment methods traditionally had been developed on the basis of clinical experience and intuition, with little rigorous validation of their effectiveness (Woody et al. 1991).
The Andrew Johnson alcoholism debate is the dispute, originally conducted among the general public, and now typically a question for historians, about whether or not Andrew Johnson, the 17th president of the United States (1865–1869), drank to excess. Metronidazole is an antibacterial agent that kills bacteria by damaging cellular DNA and hence cellular function.92 Metronidazole is usually given to people who have diarrhea caused by Clostridioides difficile bacteria. Patients who are taking metronidazole are sometimes advised to avoid alcohol, even after 1 hour following the last dose. Although older data suggested a possible disulfiram-like effect of metronidazole, newer data has challenged this and suggests it does not actually have this effect. 2010—To celebrate NIAAA’s 40th anniversary, the Institute published a special double issue of its peer-reviewed journal, Alcohol Research & Health that describes the Institute’s public health impact and multidisciplinary contributions to alcohol research.
For global public health perspectives and low-risk drinking frameworks, see a study and policy summaries from the World Health Organization. The NIAAA continues to evolve its research strategies, recently focusing on the biological mechanisms of alcohol misuse, improving treatment disparities, and enhancing public health responses to alcohol-related challenges. With ongoing support for studies and outreach, the NIAAA remains committed to fostering a better understanding of alcohol-related problems and promoting healthier communities. As these findings illustrate, susceptibility to complex behavioral disorders such as alcoholism is not likely to be determined by a single gene.
Though reports vary on risks and benefits, “no level of alcohol consumption is safe for our health,” the World Health Organization said in 2023. Since its founding in 1970, the NIAAA has built a solid base of biomedical and behavioral knowledge that has been applied to improved prevention and treatment of alcohol-related problems. Building on evidence-based findings, the NIAAA promotes government policies, medical practices, interventions, and outreach programs that effectively address alcohol abuse. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines binge drinking as a pattern of drinking alcohol that brings blood alcohol concentration to 0.08%—or 0.08 grams of alcohol per deciliter—or higher.
