Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- Brain inflammation due to high alcohol intake may affect thinking, memory, and concentration. Researchers want to measure this using positron emission tomography (PET). Objective: \- To study how excessive alcohol consumption affects brain function. Eligibility: * Adults 30-75 years old who are moderate or severe alcohol drinkers. * Healthy volunteers. Design: * Participants will be screened with medical history, physical exam, interview, and blood and urine tests. Their breath will be tested for alcohol and recent smoking. * Phase 1: * Participants will stay in the hospital 3 days. They will have blood and heart tests and daily urine tests. * A small plastic tube will be inserted by needle in each arm. One will go in a vein, the other in an artery. * Participants will have 2 PET scans with 2 different radioactive compounds. Participants will lie on a bed that slides in and out of the scanner with a cap on their head. * Participants will have magnetic resonance imaging (MRI) scans. Participants will lie in the scanner either resting with their eyes open or while performing an attention task. * Participants will have tests of memory, attention, concentration, and thinking. They may answer questions, take tests, and perform simple actions. * Phase 2 of the study will only be done if Phase 1 results show brain inflammation. * Phase 2 will repeat Phase 1. * For healthy volunteers, Phase 2 will begin 3 weeks after Phase 1. * Other volunteers must not have alcohol for at least 3 weeks and stay in a hospital up to 4-6 weeks between Phase 1 and Phase 2. After Phase 2, they will have 5 follow-up calls over 3 months.
