The purpose of this protocol is to create a mechanism whereby the intramural program of the NIAAA can evaluate and treat a broad range of people with drinking problems at the NIH Clinical Center (CC) in Bethesda, MD. Through this program, participants will receive comprehensive, state-of-the-art treatment for their alcohol, psychosocial and medical problems. The protocol will allow us to evaluate and recruit participants who will then be eligible for more focused clinical research efforts to advance the NIAAA research goals. Additionally, this protocol will allow investigators and staff to gain broad training experience in alcohol and addiction medicine through the clinical care of such patients. The protocol is open to any adult who is seeking help for a drinking problem and who is likely to qualify to participate in another NIAAA protocol. Participants will be recruited through local media and professional avenues in the Washington, DC Metro area. They will be evaluated by a nurse and physician, among others, who will determine the need for hospitalization, detoxification and to address other issues. For those needing medically supervised detoxification, a standard program of monitoring and treatment with benzodiazepines and other medications will be instituted. A standard battery of screening blood, urine and other clinically indicated tests, an electrocardiogram, chest x-ray and MRI of the brain will be done as part of the comprehensive medical and neurological assessment. Following admission, participants will undergo a series of verbal and observational-type assessments designed to evaluate psychiatric co-morbidity, psychopathology, psychosocial problems, neurocognitive function, personality and other factors relevant to alcoholism treatment. Following discharge from the inpatient program, participants will be offered up to 16 weeks standard of care behavioral outpatient treatment. At five points during the outpatient phase participants will come to the clinic for selected blood and urine tests, interviews and verbal/observational assessments to evaluate abstinence from alcohol and identify change in various psychological dimensions. During their participation in this protocol, participants will be approached to consider enrolling in other clinical research protocols such as imaging studies and drug-treatment trials. For participants willing to participate in these other protocols, other appropriate consent(s) will be obtained.
