Background:

- People with alcoholism have differences in their brains compared with healthy people. People who are dependent on alcohol also perform differently on behavioral tasks. Researchers want to find out more about these differences. They also want to see if these differences are related to DNA.

Objective:

- To see if differences in brain structure relate to personality and behavior differences in people with and without alcohol dependence.

Eligibility:

- Adults age 18 and older.

Design:

- Participants will visit the NIH Clinical Center once during the study.

- Participants will be screened with a medical history, EKG, and physical exam. They will give blood and urine samples and undergo a psychiatric interview.

- Participants will be asked about their alcohol drinking, to see if they have an alcohol use disorder.

- Participants will play three computerized games. Some will play these games inside a magnetic resonance imaging (MRI) scanner.

-MRI: strong magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides in and out of a cylinder. They will be in the scanner for about 90 minutes. They may lie still for up to 20 minutes at a time. The scanner makes loud knocking noises. They will get earplugs.

Eligibility

INCLUSION CRITERIA: ADULT PARTICIPANTS

All adult participants must have:

-Enrolled in screening protocol 14-AA-0181, Unit and Clinic Evaluation, Screening, Assessment, and Management or have been determined eligible for another NIAAA study.

-Task performance (behavioral and fMRI) only: Are cleared based on neuromotor examination as determined by the screening protocol 14-AA-0181.

EXCLUSION CRITERIA: ADULT PARTICIPANTS

-Exclusion criteria for MR scan

--Presence of ferromagnetic objects in the body that are contraindicated for MRI of the head (pacemakers or other implanted electrical devices, brain stimulators, some types of dental implants, aneurysm clips, metallic prostheses, permanent eyeliner, implanted delivery pump, or shrapnel fragments) or fear of enclosed spaces. Eligibility will be determined by a "MRI Safety Screening Questionnaire" and verified, if necessary, by a physician.

--Cannot lie comfortably flat on back for up to 2 hours in the MRI scanner.

--Uncomfortable in enclosed spaces (has claustrophobia) such that they would feel discomfort in the scanner

--Women: Are pregnant

--Are left-handed.

-Inpatient participants with alcohol dependence who have symptoms of alcohol withdrawal as indicated by the most recent measurement within the past 30 days, as measured by the Clinical Institute Withdrawal Assessment (CIWA-Ar) score >= 8 (with sub-score more than zero for orientation and more than 2 for all others).
