What this study is about
Background: \- About 17 million adults had an alcohol use disorder in 2012. Researchers want to follow people that have alcohol problems and want treatment, as well as those who do not want treatment and healthy volunteers. They also want to gather information on people with and without alcohol problems, including information on genes and biological processes in the body..

Background: \- About 17 million adults had an alcohol use disorder in 2012. Researchers want to follow people that have alcohol problems and want treatment, as well as those who do not want treatment and healthy volunteers. They also want to gather information on people with and without alcohol problems, including information on genes and biological processes in the body.. This will help them better understand, prevent, and treat alcohol problems. Objective: -To look at a broad range of traits in people who are healthy people and people with alcohol problems. To study them for potential eligibility for other research protocols conducted at the NIH Clinical Center. Eligibility: * Adults age 18 and older. * Not being pregnant or imprisoned. Design: * Participants will have a physical exam. They will answer questions about their health and alcohol and drug use. They will have an electrocardiogram to check their heart. They will have blood, urine, and breath alcohol tests. * Participants without alcohol problems, or who have them but do not want treatment, can sign the second consent for screening and research. * Participants that have alcohol problems and want treatment will be treated at the NIH Clinical Center. They will be offered to sign the second consent at a later time. * Participants may join an inpatient treatment and detox program. It could last up to 6 weeks. Or they may join an outpatient program. Some may do both. * After discharge, participants may be called and asked questions about their drinking and health. * If participants sign the second consent, they: * will complete paper- and computer-based questionnaires. * will give blood samples. * may have a brain scan using magnetic resonance imaging. They will lie on a table that slides in and out of a cylinder that takes pictures. The machine makes loud noises. They will get earplugs.
Primary outcome measures
Obtain phenotypic assessments
Time frame: CROSS SECTIONAL
To gather characterization measures for individuals wishing to participate in this protocol, including a standardized set of clinical, behavioral, biochemical, and structural MRI-based phenotypic assessments, as well as whole genome genotypes
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- As this is a natural history protocol of alcohol use as a continuum, in order to be eligible to participate in this study, an individual must meet the following criterion:
- Age \>=18 years of age
- Willingness to complete the study including genetic and MRI tests. We will assign participants to one of two groups in this study:
- Treatment-seeking individuals (Patients that want to stop alcohol use and will require medical management to achieve sobriety) and
- Non-treatment-seeking participants (Patients or healthy volunteers who want to continue their current alcohol use). All participants are initially phone-screened for eligibility and their desire for treatment of AUD (or lack of it) will determine their group allocation. Their self-report of health status, pregnancy, legal status, and willingness to complete the study including the genetics and MRI test will be assessed in the phone screen and determine eligibility.
Exclusion criteria
- This is a natural history protocol of alcohol use as a continuum. Potential participants are pre-screened on the phone and, based on the information provided on the phone, the following categories are excluded because they are not suitable study participants for this protocol:
- Individuals \< 18 years of age
- Pregnant candidates
- Candidates having a severe medical or mental health disorder that would impair participation in the study All participants are initially phone-screened for eligibility: age, legal status, pregnancy, and severe medical conditions will be assessed using information reported in the phone screen to determine eligibility for the study.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
