Filter by:The purpose of this study is to determine whether the catechol-O-methyltransferase (COMT) inhibitor tolcapone, relative to placebo, affects response to alcohol, decision-making, brain activation associated with alcohol cue reactivity, response inhibition, and selective attention, or alcohol drinking.
Primary: The primary objective of the study is to compare the efficacy of intranasal oxytocin in reducing the weekly percentage of heavy drinking days over the 10 weeks of maintenance treatment among subjects with moderate to severe Alcohol Use Disorder (AUD). A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men. Secondary: Secondary objectives include assessment of other measures of the effects of oxytocin compared with placebo on reduction of alcohol use as well as effects on psychological assessments, alcohol craving, alcohol-related consequences, cigarette smoking and other nicotine use, retention in the study, safety, and application site (nares) tolerability throughout the study.
This study is composed of two phases. Phase 1 will determine baseline demographic characteristics of participants, currently drinking harmful amounts of alcohol, who would be interested in an alternative treatment option to reduce alcohol consumption. Once baseline data is collected, participants will then be informed that the intervention is an exercise programme and those interested will be offered participation in Phase 2: a two-arm randomised controlled study. If eligible, participants will be randomly assigned to either: 1) a 12 week combined exercise programme and NHS standard care group, or 2) 12 weeks of NHS (National Health Service) standard care only group. The aims are to study the feasibility of conducting a randomised controlled trial in this cohort and to determine the effectiveness of the exercise programme to reduce alcohol consumption, improve physical and mental health among people drinking harmful amounts of alcohol, compared to standard NHS care. Assessment visits, measuring alcohol consumption, mental health and physical health, will be conducted at baseline, and at Weeks 13, 24, 36 and 48 since commencement of the intervention period. Focus groups will take place during the 2nd and 12th week of the exercise programme where qualitative feedback on the exercise programme will be collected.
This study examines the selective attention to emotional- and alcohol- associated cues in alcohol- dependant and healthy participants.
The goal of this study is to investigate a treatment approach for alcohol use disorder (AUD) using a novel form of brain stimulation called deep repetitive transcranial magnetic stimulation (rTMS). The investigators will be targeting frontal regions of the brain that are important for memory and decision making. These brain regions have been shown to be impaired in patients with AUD. Previous studies have mostly used rTMS to a different frontal brain region that is not as deep. These studies have shown that rTMS can reduce craving for alcohol, but there is a lack of research showing that rTMS impacts alcohol consumption.
For this protocol, the investigators plan to collect pilot data to examine sex differences in guanfacine's effect on 1) counteracting stress and stimulation based drinking behavior in the laboratory and 2) improving clinical outcomes during a subsequent treatment phase.
This is a double-blind, 2-group randomized controlled trial evaluating the effects of topiramate versus placebo in patients with comorbid PTSD and moderate-to-severe AUD. This trial will provide one of the first rigorous tests of whether the effects of topiramate in AUD generalize to patients with co-occurring PTSD, and one of the first rigorous tests of whether topiramate has beneficial effects on PTSD symptoms in this population. It will be the first study to test whether the rs2832407 genotype predicts clinical response to topiramate for AUD and PTSD in patients with both disorders. Further, it will contribute to the understanding of topiramate's mechanisms of action in the co-morbid AUD/PTSD population, and to the discovery of predictors of treatment response.
Hazardous drinking (HD) is a major public health burden worldwide with significant morbidity and mortality. To reduce HD, the World Health Organization (WHO) recommends using Screening, Brief Intervention, Referral to Treatment (SBIRT). Mobile health technology (mHealth), such as the mSBIRT app, is a promising tool for widespread cost-effective delivery of evidence-based HDS by community health workers (CHWs) because of its potential to increase fidelity, effectiveness, and sustainability. Community I-STAR Mozambique comprises three phases: 1) mSBIRT adaptation, 2) a cluster-randomized trial, and 3) scale-up of the most cost-effective intervention. Community I-STAR Mozambique will scale-up a cost effective, sustainable program and inform policy applicable to Mozambique and other LMICs.
For this protocol, the investigators plan to conduct a pilot study evaluating the effect of propranolol on alcohol consumption. Using a parallel design, the investigators plan to randomize 20 non-treatment seeking adults with alcohol use disorders (DSM-5) to propranolol extended release (160mg/day or placebo; n=10 per cell) to evaluate whether propranolol reduces alcohol self-administered in the laboratory. Importantly, the investigators will evaluate whether propranolol counteracts stress-induced effects on alcohol self-administration. Following titration to steady state medication levels over a 2-week period, each subject will complete two laboratory sessions consisting of a well validated method for inducing stress or neutral/relaxing state (order counterbalanced), followed by a 2-hour alcohol self-administration paradigm known to be sensitive to medication effects.
Background: Problem drinking affects nearly half the people who drink alcohol. Drinking alcohol affects a person s social behavior and brain structure, but researchers don t have a good understanding of how. They want to test a technique called neurofeedback to learn more about how to treat problem drinking. Objectives: To study what happens in the brains of people who drink alcohol when they look at pictures of social things and of alcohol. To learn if people can control brain activity in a magnetic resonance imaging (MRI) scanner and if this helps people with drinking. Eligibility: Adults ages 21 65 who have an alcohol use disorder. Healthy volunteers ages 21 65 Design: Participants will be screened with Physical exam Medical history Blood, urine, and heart tests Mental health interview Questions about their alcohol drinking. At each session, participants will have: A urine test for drugs and pregnancy. If they test positive, they cannot participate. A breath alcohol test and assessment for alcohol withdrawal. Participants will complete surveys, talk to researchers about behaviors, and play games. Participants will have MRI brain scans. The scanner is a metal cylinder in a strong magnetic field. They will lie on a table that slides in and out of the scanner for 1 2 hours. Participants will do tasks in the scanner: They will look at pictures, sometimes of alcohol. They will try to hit a goal. Some participants will get feedback during this task. They will see how their brain activity changes or how someone else s changes. Participants may have follow-up phone questions at least 3 times over about 6 months.
