Filter by: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).
The purpose of the study is to determine if ondansetron, as an add-on therapy, is associated with reduced depressive symptoms and alcohol use in outpatients with bipolar disorder (BPD), cyclothymic disorder, schizoaffective disorder (bipolar type) and major depressive disorder (MDD) with mixed features. The investigators will also use blood samples to determine if the genotype for the serotonin transporter gene is associated with response to ondansetron.
This is a prospective HIV cohort that aims to establish causes of liver disease among HIV-infected individuals in Zambia, including viral hepatitis and alcohol.
Current pharmacotherapies for alcohol use disorders (AUDs) have limited efficacy. Thus, the development of effective treatments for AUDs represents an important public health objective. Repositioning, i.e. using existing approved drugs for other indications, represents a fast and economically feasible approach for drug development. Ivermectin (IVM) is an FDA-approved antiparasitic medication that can significantly reduce alcohol intake in mice, suggesting that it may be useful in the treatment of AUDs in humans. The goal of this project is to provide key clinical evidence that IVM can be repositioned as a novel therapeutic agent to treat AUDs.
This project will involve the development and initial evaluation of a promising computer-based intervention to improve the primary care management of risky alcohol use among Veterans. The intervention uses a Relational Agent, an on-screen "person" that establishes a relationship with the Veteran to promote positive health behaviors. This study will determine how Veterans interact with this system, how it can be tailored to Veterans' preferences, and its potential effect on risky drinking. If ultimately proven effective, the Relational Agent will have several impacts on Veterans and their health care, including: - (1) lower rates of risky drinking in Veterans - (2) improved rates of brief counseling for Veterans with excessive alcohol use - (3) increased proportion of Veterans referred to Mental Health for alcohol disorders - (4) improved care for Veterans with low levels of health literacy. This study directly supports Secretary Shinseki's Transformational Initiative to employ state-of-the-art information technology to improve quality and access of Veterans' health care.
This study will elucidate the pharmacogenetic effects of the Asn40Asp SNP of the OPRM1 gene on biobehavioral and neural markers of response to naltrexone in individuals of East Asian descent, an ethnic group most likely to express the positive predictive allele.
This study investigates the effect of a computerized approach/avoidance retraining (aka cognitive bias modification) over and above treatment as usual for patients in treatment for substance use disorders. The computerized training entails viewing pictures of drug and non-drug related stimuli, and then using the computer to make the drug pictures smaller and the non-drug pictures larger. Participants will also take part in an EEG/event-related brain potential assessment at the beginning and end of treatment to identify brain measures that are associated with treatment response.
The goal of this study is to test the efficacy of extended-release naltrexone and harm reduction counseling in reducing alcohol-related harm among homeless people with alcohol dependence.
The study uses neurobiological measures through brain imaging, neuropsychological measures, and selfreport measures to try to understand how an effective treatment for alcoholism works. On the whole, less than 50% of people with alcoholism get better with treatment. This study will help researchers develop better treatments for alcoholism because if the investigators know why the treatments the investigators use are working, and in whom the treatments work best, then the investigators may be able to make treatment more effective by targeting treatments to individuals who would be most likely to benefit and by guiding development of more effective treatments in the future.
The purpose of this study is to learn how best to treat substance use disorders in an HIV clinic setting. Specifically, the purpose of this pilot study is to learn if extended-release naltrexone (XR-NTX) would be a feasible and acceptable treatment for HIV-infected individuals with opioid or alcohol use disorders.
