Filter by:Background: - People who are dependent on alcohol drink even when they know something bad might happen. Researchers want to learn more about why they do this. Objectives: - To study brain response when a person plays a game in different threat conditions. Eligibility: - Healthy right-handed adult heavy drinkers age 21 60 - Healthy right-handed adult light drinkers age 21 60 Design: - Participants will be screened with medical history, physical exam, and blood and urine tests. They will have an EKG and psychiatric interview. - Participants will have one or two clinic visits. - Participants will be asked about their alcohol drinking. - They will choose a snack and alcoholic beverage that they must drink in 5 minutes. After their breath alcohol content (BrAC) is zero, they will play a game in the MRI scanner. - The scanner is a metal cylinder that takes pictures of the brain. Participants lie on a table that slides in and out of the cylinder. They will be in it for about 90 minutes, lying still for up to 20 minutes. - During the MRI, participants will play a simple computer game to earn food or drink points under different threats of electric shock. Points can be exchanged for food or alcohol after the game. Sometimes, participants will receive a mild electric shock through a metal disk on the wrist. Electric shocks will only happen if the participant tries to earn a reward point. - After the MRI, participants use their points for another drink and snack. They will stay at the clinic until their BrAC is low, usually within 3 hours. Participants cannot drive themselves home. - Participants will have a follow-up phone call the next day.
The present study examines the efficacy of the Community Reinforcement and Family Training (CRAFT) for Concerned Significant Others (CSOs) of individuals with alcohol use disorders (AUDs) using a randomized waiting list (WL) control group. It is hypothesized that after the Intervention group has received CRAFT and prior to the WL- group having received CRAFT, treatment utilization of individuals with AUDs are substantially elevated in the Intervention group.
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.
Background: - Scientists know that alcohol use disorders affect brain structure. They want to know more about the effects of alcohol use disorders on a person s behavior. They want to develop tasks that can be done inside a scanner that can help them better understand these effects in later studies. Objective: - To develop tasks that investigate a person s behavior that can be used in later studies. Eligibility: - Inpatient participants of another study. They must be physically healthy right-handed adults 18-60 years old. - Healthy right-handed volunteers 18-65 years old. Design: - Participants will be screened with medical history and physical exam. They will have an EKG to record heart activity. They will give blood and urine samples and have a psychiatric interview. - Participants will have between one and three visits. - Participants will be asked about their alcohol drinking to see if they have an alcohol use disorder. - Participants will complete one of three simple computerized tasks either inside the magnetic resonance imagining (MRI) scanner or outside of it. - The MRI scanner takes pictures of the brain. The scanner is a metal cylinder. Participants lie on a table that can slide in and out of the cylinder. They will be in the scanner for about 60 minutes. They may have to lie still for up to 20 minutes. The scanner makes loud knocking noises, but they will get earplugs.
The main aim of this research is to investigate whether the use of cognitive event-related potentials is an interesting way to identify subgroups of alcoholic patients displaying specific clinical symptoms and cognitive disturbances in order to help clinicians to adapt the pharmaceutical approach to the specific needs of the patient. Nowadays, a fundamental question remains: How can investigators identify among alcoholic patients who are likely to benefit from the use of naltrexone, acamprosate or baclofen, and those who are not? The goal of this application is to identify subgroups of alcoholic patients displaying specific clinical symptoms and cognitive disturbances linked to consistent biological markers. Investigators propose that this might help clinicians improve their treatment of alcoholic patients by focusing therapy on individual cognitive disturbances, and by adapting pharmaceutical approaches to the identified brain pathophysiology. In other words, investigators suggest that specifying the cognitive profile of each individual patient may help clinicians in their choice of a suitable drug program. To reach this aim, investigators suggest that a joined investigation of early (P100) and late (P300) brain event-related potentials (ERP) components may help create subgroups of alcoholic patients with homogenous cognitive deficits, and that this ''classification'' might help optimize drug treatment. More precisely, investigators suggest that relapse in chronic alcoholism is partly due to (1) the preferential attentional allocation to alcohol-related information (e.g. the sight of a bottle of wine). As the P100 component has already been shown to be enhanced by motivationally relevant stimuli, investigators think that this component is well-suited for this purpose; and (2) the impairment of the inhibitory control, which is necessary to suppress an inappropriate prepotent response. The Go/No-Go task is a simple procedure, which has already proven to be highly reliable to evidence a deficit in inhibitory control processing in alcoholics, indexed by a No-Go P3 of decreased amplitude and less anterior topography. In summary, investigators have two simple experimental procedures, an oddball task and a Go/No-Go task, which can be easily carried out in clinical settings, and which can provide interesting data concerning, respectively, the existence of an implicit attentional bias towards alcohol-cues and the deficit of inhibitory control towards a prepotent response, through the observation of well-known and well-described cognitive ERP components, i.e. the P100 and P3b components. The main goal of this project will be to test the effect of different drug medications on both attentional (P100) and inhibitory (P300) deficits observable in alcoholic patients.
The aim of this project is to assess reward- based learning behavior and its association with alterations in dopaminergic and glutamatergic transmission in detoxified alcohol-dependent patients and matched controls. The investigators will explore how these alterations interact with clinical and psychosocial factors which can modify the relapse risk and learning deficits. Patients will be detoxified in an inpatient setting. Clinical assessments, behavioral paradigms of learning and brain imaging will be carried out within at least 4 half- lives after any psychotropic medication. The investigators will implement and apply functional imaging paradigms assessing Pavlovian-to-instrumental transfer and reversal learning tasks and associate model parameters of learning with alcohol craving, intake and prospective relapse risk. In this project, the impact of the dopamine x glutamate interaction on learning deficits and consecutive relapse probability is targeted with [18F]fallypride PET and the measurement of absolute concentrations of glutamate with magnetic resonance spectroscopy (MRS).
In this study, eligible alcoholic inpatients recruited from a specialized clinic for addiction treatment, filling inclusion criteria and not showing any exclusion criteria, were randomized to receive the repetitive (10 sessions, every other day) bilateral dorsolateral Prefrontal Cortex (dlPFC: cathodal left / anodal right) tDCS (2 milliamperes, 5 x 7 cm2, for 20 min) or placebo (sham-tDCS). Craving to the use of alcohol was examined before (baseline), during and after the end of the tDCS treatment. Based in our previous data, our hypothesis was that repetitive bilateral tDCS over dlPFC would favorably change craving in alcoholism and this would be a long-lasting effect.
Benzodiazepines (BDZs) are the gold standard in the treatment of alcohol withdrawal syndrome (AWS). Gamma-Hydroxybutyric acid also known as sodium oxybate (SMO) has been tested as a treatment for AWS with encouraging results. Aim of this phase IV, multicenter randomized double-blind, double dummy study is to evaluate the efficacy of SMO in comparison to oxazepam in the treatment of alcohol withdrawal symptoms (AWS).
This 3 weeks study examines the correlation between stress and alcohol using an ecological, prospective design.
With the aging of western societies in the coming years combined with increasing alcohol consumption among elderly, the number of elderly with alcohol problems is expected to rise considerably. Elderly patients are often lonely; suffer from feelings of loss, fear to be a burden on their children and on society, and feel powerless. On the surface their alcohol related problems seem less severe that those of the middle-aged patients while in reality co-morbidity and social issues complicate alcohol dependency. Currently, no specific treatment tailored for alcohol use disorder among elderly is available. Consequently they receive either no treatment, are given brief advising from the general practitioner or are referred to treatment at specialized treatment institutions with no specific treatment for elderly. The investigators propose a study aimed at developing and testing an outpatient behavior therapy program for alcohol use disorders for seniors (60 years and older), which - if effective - can be easily implemented in routine care. Three centers from Denmark, Germany and USA (New Mexico) will participate. All three centers have a long and extensive experience with alcohol treatment and alcohol research. Patients fulfilling the DSM 5 criteria for alcohol use disorder are eligible for the study. After informed consent participants will be randomly assigned to either Motivational Enhancement Therapy (MET), four sessions/one session per week or MET followed by Community Re-enforcement Approach (CRA), eight sessions/one session per week - thus 12 weeks of treatment in total. 50% will receive MET and 50% MET+CRA. Primary outcome is percentage of patients with abstinence or controlled use (alcohol intake of equivalent blood alcohol content equal to or less than 0.5‰.). A total of 1000 patients will be enrolled. Participants will be assessed with a battery of international validated instruments measuring drinking pattern as well as key elements of treatment. Participants are assessed before initiation of treatment, at the end of MET treatment (four weeks), at the end of MET+CRA treatment (12 weeks), at 6 months, and at 12 months.
