Filter by:The purpose of this research is to examine the effects of exercise of different intensities on psychological, physiological, biochemical, physiological and alcohol-related parameters in individuals with alcohol use disorders (heavy drinkers and alcoholic patients) in order to investigate possible biochemical mechanisms by which exercise may be a healthy alternative to alcohol abuse. For that purpose, a control group of individuals that do not exceed the limits for moderate alcohol use will be included.
Alcohol Use Disorders (AUDs) have a significant public health impact and are highly prevalent in Veterans. Alcohol related brain effects on neurocognition (attention, memory and executive function) reduce ability to benefit from current treatments. These cognitive impairments are especially common in the early phase of recovery, persist over years and get worse with age. Recent research suggests that cognitive remediation therapy (CRT) may improve attention, memory and executive function in other disorders, and the investigators just completed pilot study with AUD Veterans found significantly greater improvements for those receiving CRT. The proposed study examines AUD outcomes and neurocognitive improvements when CRT is combined with a standardized alcohol treatment. The investigators hypothesize that CRT will improve neurocognition and AUD outcomes more than standardized alcohol treatment alone. Findings will determine whether CRT augmentation can benefit Veterans with AUDs.
Using theTEMA (test system for development of medications for alcoholism) it can be shown, that naltrexone administration reduces the willingness to perform work for alcohol infusion in a laboratory experiment.
The Soberlink Cellular device, in its original packaging, along with the QuickStart guide will be provided to the end user in a simulated home use environment or by Rx in clinic. The patient labeling will be in the format intended for distribution. Ten (10) Rx subjects will be provided instruction for use in clinic for the Soberlink Cellular device while an additional ten (10) Rx subjects will be provided instruction for use in clinic for the Soberlink Cellular device and Sober Sky web portal. An additional ten (10) simulated home use subjects will be provided instruction for use for the Soberlink Cellular device while an additional ten (10) simulated home use subjects will be provided instruction for use in clinic for the Soberlink Cellular device and Sober Sky web portal. All subjects will be provided with a post-test questionnaire on how to operate the device. The post-test questionnaire will collect information regarding device use. The device's use will be compared with identified risks to determine if the percentage of failures is within the study protocol success criteria. Additionally, measurable usability criteria for specific, critical steps will be evaluated.
96 recently detoxified alcoholics will be randomized to receive either 3 sessions ketamine (0.8 mg/kg IV over 45 minutes) or placebo plus manualised psychological therapy, or 3 sessions of ketamine or placebo plus simple psychoeducation. Patients will be assessed at 3 and 6 months on a range of psychological and biological variables. Primary endpoints will be % days abstinent at 6 months and relapse rates at 6 months. Secondary endpoints include depressive symptoms, craving, quality of life.
The purpose of this study is to determine whether extensive internet based cognitive behavior treatment program with guidance is a more effective method to treat individuals with alcohol use disorders than a briefer cognitive behavior treatment program without guidance.
It is well-established that many substance misusers experience impairment in cognition (thinking skills), particularly those needed to regulate and monitor behaviour and ensure that goals are achieved. According to the dual-process model, addiction arises from an imbalance in 'bottom-up' processing i.e., overactive automatic (impulsive) processes that drive behaviours and impaired 'top-down' controlling processes that stop behaviours associated with negative consequences. As a result, the individual becomes more sensitive to cues in their environment (e.g., alcohol images) that trigger the addictive behaviour. Cognitive-bias modification (CBM) is a novel, computer-based training paradigm that trains the brain to pay less attention to negative/harmful cues and more attention to positive or neutral cues. This approach minimizes the overactive 'bottom-up' processes and improves the 'top-down' control processes of unhealthy behaviors which enables the addicted individual to make better decisions. Recently, CBM has been used with addicted population to alter the tendency to approach alcohol, with one German study showing that a 4-session training programme was associated higher rates of abstinence at one-year (Wiers et al., 2011). The current study examines whether a novel computer based training programme alters cognitive biases (the tendency to approach alcohol related stimuli) in alcohol-dependent inpatients, and examine whether this enables them to be better at decision-making more generally, and its impact on craving and post-discharge abstinence rates. The study will also explore whether individual differences in impulsivity and sensitivity to reward and punishment determine response to the training programme. This will be achieved using a parallel-groups randomized superiority trial design involving approximately 80 patients attending inpatient withdrawal programmes in Victoria. The findings are likely to have implications for the design and delivery of psychosocial interventions delivered during early recovery from alcohol-dependence to optimise treatment effectiveness.
The traditional paradigm that relies upon training physicians and nurses or uses on-site interventionists to perform screening, brief intervention, and referral to treatment (SBIRT) for alcohol has proven unsustainable in most clinical settings. The Remote Brief Intervention and Referral to Treatment (R-BIRT) for alcohol is an innovative telehealth service model with potential to improve public health through evidence based counseling for patients who exceed the NIAAA low risk drinking limits or have evidence of an Alcohol Use Disorder with professional and self-help treatment. For those that are appropriate, the R-BIRT service will provide facilitated referrals to specialized alcohol abuse treatment. The service model is being studied in the emergency department (ED) setting to demonstrate its utility in a medical setting with a very high prevalence of risky alcohol use and Alcohol Use Disorders; however, the model is relevant and will be accessible to a broad array of healthcare settings, including primary care practices. Our new model, the R-BIRT, challenges the prevailing paradigm and offers the promise of not only clinical efficacy but increased cost effectiveness as well.
Extending previous findings, and applying a novel multi-method translational approach, this project hypothesizes that there are alcohol-related neuroendocrine and neural changes observable in acute and protracted abstinence, and which can accurately classify future relapse and treatment outcome in separate alcohol dependent (AD) patient samples, thereby validating them as biomarkers of relapse, with potential clinical utility as prognostic markers in identifying and treating those most susceptible to relapse.
The investigators will examine clinical alterations in learning and automated approach behaviour and their neurobiological correlates in alcohol-dependent patients and healthy social drinkers and assess whether they are affected by a Zooming Joystick Training (ZJT; randomized "verum" versus "placebo" training) which trains subjects to habitually push alcohol pictures away. The investigators will test whether activations following treatment predict relapse rate (primary outcome measure) and the prospective amount of alcohol intake (secondary outcome measure) within a six-month follow-up period. Using fMRI, the investigators will use the Pavlovian-to-Instrumental-Transfer (PIT) paradigm established during the first funding period to distinguish the effects of appetitive, aversive, and drug-related Pavlovian cues on automated instrumental approach behaviour and to assess ZJT training effects comparing functional activation before and after ZJT training. The investigators will also scan subjects during performance of a short standard working memory task. Behaviourally, aspects of impulsivity will be assessed with the Value-Based Decision Making (VBDM) Battery. Scanning will be repeated after ZJT training to assess its effects on the neural correlates of Pavlovian-to-Instrumental transfer (PIT).
