Filter by:The purpose of this study is to explore whether frontal brain activation in response to stress varies as a function of the presence or extent of early trauma and whether or not this effect is greater in women compared to men. To examine the effect of stress on thinking and remembering. To examine the separate and interactive effects of stress, addiction, withdrawal, and genetics; and to examine fMRI brain activation associated with stressful, reward-related-cue and neutral/relaxing audiotaped scripts,visual images and emotional video clips in addicted individuals and in healthy controls.
The purpose of this study is to determine whether varenicline is effective in the treatment of alcohol dependence in smokers.
The purpose of this study is to evaluate the efficacy of ketamine in reducing depressive symptoms in subjects with a comorbid major depressive episode and alcohol dependence. The investigators hypothesize the following for the present study: A single dose of ketamine will induce a rapid, robust and sustained reduction in depressive symptoms in subjects with a comorbid major depressive episode and alcohol dependence relative to placebo as defined by change in Hamilton Depression Rating Scale total scores at 72 hours post infusion. A single dose of ketamine can be delivered safely, with minimal adverse events or complications, in subjects with a comorbid major depressive episode and alcohol dependence.
The primary hypotheses under test are that alcohol dependent subjects treated with mifepristone will report decreased craving for alcohol following cue- and stress induced exposure in the laboratory and report fewer symptoms of protracted abstinence (e.g., craving, anxiety, mood and sleep disturbances) under naturalistic conditions, significantly more than those treated with placebo.
This trial is an open-label pilot study (N = 10) designed to assess the effects of psilocybin in alcohol dependent participants, demonstrate the feasibility of the integrated behavioral/pharmacologic intervention, and provide preliminary outcome and safety data. Participants will receive psilocybin orally in two all-day administration sessions, conducted in a secure outpatient psychiatric setting, in a dose range that has been well-tolerated in recent studies. Psilocybin administration will occur in the context of a behavioral intervention including a total of 12 sessions over 12 weeks, incorporating Motivational Enhancement Therapy (MET (Miller, Zweben et al. 1992; Miller 1995), based on Motivational Interviewing (Miller and Rollnick 2002)) with booster sessions, as well as preparation before and debriefing after the psilocybin administration sessions. The MET will incorporate attention to spirituality as well as drinking behavior as a primary subject of change. Drinking outcomes and changes in several potential mediators of treatment effect, including motivation, self-efficacy, craving, depression, anxiety, and spiritual dimensions of the experience, will be measured during treatment and for 24 weeks after the end of treatment. The investigators hypothesize that drinking will decrease following the psilocybin sessions, and that increases in motivation, self-efficacy, and spirituality (primary contrast 12 weeks vs. baseline) will be observed among study participants.
This study examines the effectiveness of Cognitive Behavioral Analysis System of Psychotherapy (CBASP) in reducing both alcohol consumption and depressive symptoms in adults who are chronically depressed and alcohol dependent.
The purpose of this study is to determine whether the drug prazosin is effective for the treatment of alcohol dependency and symptoms of Posttraumatic Stress Disorder (PTSD).
It is proposed to test metadoxine (MTDX) that it is hypothesized to be significantly beneficial for the treatment of alcoholism and ALD. Metadoxine is currently approved in Europe for acute and chronic alcohol intoxication but has never been tested in the US. Furthermore, MTDX is used in Europe to treat ALD. Preliminary evidence shows that MTDX reduces alcohol consumption in AD individuals. If the role of MTDX in reducing alcohol consumption and improve liver function is confirmed by a rigorous study design, then MTDX might represent a truly innovative pharmacotherapy for AD, given the potential to be used for AD individuals with ALD. However until this proposal, MTDX has never been investigated as a treatment for AD able to reduce both alcohol consumption and improve alcohol-related liver damage via a double-blind placebo-controlled study. This project therefore proposes to conduct a 12-week (followed by a 3-month follow-up), double-blind, placebo-controlled, between-subject randomized clinical trial with MTDX (500mg t.i.d.) in AD individuals.
The mesolimbic dopaminergic reward system is a key structure underlying addictive behaviour in alcohol addiction and is under control of prefrontal glutamatergic neurotransmission. The aim of the present multicenter-study in Berlin, Bonn and Mannheim is to use functional magnetic resonance imaging (fMRI) in alcohol addiction for endophenotyping in order to study the relevance of genetic variation, in particular in dopaminergic and glutamatergic genes, for addiction. The investigators will use a temporal discounting and a cue reactivity paradigm in alcoholics and healthy controls in order to 1) test the impact of genetic variation on activation of the mesolimbic system in these populations and to 2) to test their predictive effects for treatment outcome in alcoholics. The subproject will thus bridge animal research on genetically determined cue reactivity and human studies in alcoholics. Furthermore, the investigators will link these results to the measurement of glutamate and glutamine with magnetic resonance spectroscopy (MRS) in subproject SP14.
The overall objective is to study if training and support, financial reimbursement and referral to an internet based brief intervention programme, singly or in combination, may increase implementation of evidence based methods of identification and brief intervention for excessive alcohol consumption in routine primary health care.
