Filter by:Alcohol-dependence is the most widespread addiction in Western countries and leads to a wide range of impairments at cerebral and cognitive levels. It has also been showed that alcohol-dependence is associated with emotional disturbances, particularly for the decoding of emotional facial expressions (EFE). In view of the crucial role played by EFE to develop and maintain satisfactory interpersonal relations, this emotional processing impairment may have deleterious consequences on alcohol-dependent patient's social well-being, and this deficit is thus of particular clinical interest. Nevertheless, this deficit has up to now been evaluated only by means of experiments using paradigms with low ecological value (i.e. presentation of EFE in isolation and in the central vision field), while in the real life, emotional stimuli are most frequently appearing together with other emotional stimulations (particularly voices) and in the peripheral vision field. Moreover, the cerebral correlates of this emotional deficit are still to be determined. The present study thus aims at exploring the Emotional Facial Expressions (EFE) decoding in alcoholism using a more ecological paradigm, based on peripheral presentation of emotional crossmodal stimuli (i.e. the simultaneous presentation of emotionally congruent face and voice). Main aim: Determining the electrophysiological characteristics (latencies and amplitudes) of the event-related components elicited among recently detoxified alcohol-dependent participants, while performing an emotion-detection task on crossmodal stimuli (voices and/or faces) presented centrally or peripherally, and comparing these characteristics with those obtained among paired healthy participants. Secondary objectives: - Exploring the electrophysiological pattern modifications among alcohol-dependent participants for the emotional faces and voices decoding (unimodal conditions), using spatio-temporal analyses methods. - Exploring the electrophysiological waves associated with peripheral crossmodal stimuli processing among healthy participants. - Exploring the behavioral correlates (reaction times and accuracy) of the emotion-detection task among alcohol-dependent participants while processing peripheral stimuli. - Exploring the psychopathological comorbidities among alcohol-dependent participants and their influence on the behavioral and electrophysiological results.
The purpose of this study is to investigate the effectiveness of 2 different therapy courses for undergraduate college students who binge drink and experience depressive symptoms.
Background: - Drinking too much alcohol can injure cells in the body. Inflammation is the body s reaction to injured cells. Studies show that inflammation can cause cravings for alcohol. Researchers want to see if piogliatazone, a drug that decreases inflammation, can reduce alcohol craving. If so, it might help develop new ways to help alcoholics with craving. Objectives: - To see if pioglitazone can reduce alcohol craving. Eligibility: - Adults between 21 and 65 years of age who are alcoholic and have been drinking within the past month. Design: - Participants will be screened with a physical exam and medical history. Blood samples will also be collected. - All participants will have inpatient treatment at the National Institutes of Health Clinical Center for the 5 weeks of the study. They will have standard treatment for alcoholism during their inpatient stay. - Half of the people in this study will have pioglitazone. The other half will have a placebo. - Participants will have different studies during their stay. These studies will include the following: - Personalized audio recordings of stressful, alcohol-related, and neutral events to monitor mood - Imaging studies to test alcohol cravings - Questionnaires about mood and alcohol cravings - Lumbar puncture to collect spinal fluid - Inflammation test to see if the study drug can block alcohol cravings - After the end of the 5-week study, all participants will be offered follow-up outpatient care through the Clinical Center, or referral to outside treatment.
The investigators are conducting a randomized clinical trial of our new web-based version of the CBT4CBT (Computer Based Training for Cognitive Behavioral Therapy) program specifically designed for alcohol to evaluate its effectiveness relative to standard outpatient counseling at the Substance Abuse Treatment Unit (SATU). The computer-based training program (CBT4CBT) focuses on teaching basic coping skills, presenting examples of effective use of coping skills in a number of realistic situations in video form, and providing opportunities for patients to practice and review new skills while receiving substance abuse treatment.
The primary efficacy endpoint examines the hypothesis that ABT-436 will decrease the weekly percentage of heavy drinking days during Study Weeks 2 through 12 (Days 8-84) as compared to placebo. A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men.
The main objective of this study is to show the effectiveness to a year of baclofen compared to placebo, on the proportion of patients with a low risk alcohol consumption or no, according to the WHO standards.
Comorbidity of alcohol use disorder (AD) and posttraumatic stress disorder (PTSD) is common. Currently available treatments often do not lead to sustained recovery from these disorders, possibly because they typically do not include exposure therapy which is considered best practice treatments for PTSD. This study compares exposure-based integrated treatment to integrated coping skills psychotherapy (a well disseminated practice) for comorbid AD and PTSD with the hypothesis that exposure therapy will allow those with PTSD to better sustain PTSD symptom reduction and reduction in alcohol use. The aim of this grant is to change common treatment practices for comorbid AD and PTSD by increasing the availability of evidence-based PTSD treatment for those with AD.
This study is examining the relative effects of alternative aftercare models for ex-offenders who are recovering from substance abuse/addiction. The study is a longitudinal, randomized field trial that assigns participants to one of three conditions: Oxford House, a professionally-run residential treatment facility, or a control condition that involves usual aftercare chosen by participants (which may include no treatment at all). Oxford Houses are self-run residential recovery homes based on the premise of mutual support. These homes do not involve professional treatment staff and the expenses (e.g. rent, utilities) are paid for by the residents. The hypothesis of this study is that Oxford House participants will have as good or better outcomes in terms of substance recovery, recidivism, and health in comparison to the participants who were assigned to the residential treatment facility, and better outcomes in comparison to the control group. In addition, the cost to government/tax payers will be substantially lower given that participants pay their own way.
This project compares Family History Positive (FHP) for alcoholism subjects to matched Family History Negative (FHN) subjects derived from the project Principal Investigator's National Institute on Alcohol Abuse and Alcoholism-funded longitudinal study of drinking behavior in a 2000 college freshman population (known as the Brain and Alcohol Research in College Students study (BARCS)). The age of these subjects is a valuable one at which to capture the transition from harmful use to abuse/dependence. This project explores the effects of memantine in a double-blind, randomized, counterbalanced manner on alcoholism risk-relevant tasks. More specifically, this project studies functional MRI tasks related to different aspects of reward and/or impulsivity-related behavior in different contexts, compares the underlying neural circuitry across tasks, and uses a pharmacologic probe of the glutamatergic system to examine NMDA/DA interactions. The combined measures provide the opportunity to advance our understanding of specific aspects of brain function related to familial alcoholism vulnerability in an already well-characterized population as some members evolve into alcohol abuse. In addition to conventional within-task analyses, functional network connectivity and allied approaches will be used to examine brain networks across tasks. The investigators will study adult male and female subjects in equal numbers who are either offspring of an alcoholic parent or are FHN matched controls. The investigators will recruit and assess a total of 84 (42 FHP and 42 matched FHN) subjects between the ages of 18-21 years on initial BARCS contact. The investigators will use 4 cognitive tasks during the functional MRI (fMRI) which include: 1) a Monetary Incentive Delay Task that distinguishes networks engaged in motivational (anticipation) and consummatory (outcome) components of reward processing; 2) a Go/No-Go Task that measures the ability to inhibit response to a pre-potent stimulus; 3) an Alcohol Cue Reactivity Task that examines Nucleus Accumbens response to alcohol-related versus matched soft drink stimuli; and 4) a Pavlovian-to-Instrumental Transfer (PIT) Task that dissects a component of the Monetary Incentive Delay (MID) Task, and provides an imaging assay of a transfer-like process that can be related to real-world drinking behavior, thus informing upon and extending the key findings from CTNA-2.
Prior research in substance dependence has suggested potential anti-craving effects of repetitive transcranial magnetic stimulation (rTMS) when applied to the dorsolateral prefrontal cortex (DLPFC). The aim of the investigators study was to investigate the effect of high frequency rTMS of the left dorsolateral prefrontal cortex compared to sham stimulation on craving and alcohol consumption.
