Marijuana use during adolescence is problematic and has long-term negative social, academic, and health consequences. Decreasing substance use at this early stage could have significant long-term benefits; however, efforts to prevent or decrease marijuana use during adolescence have only been modestly effective. This study will examine the brains of youth (ages 16-21) using magnetic resonance imaging (MRI) before and after a brief computerized training created to possibly decrease marijuana use. Each participant will receive two brain scans, one before and one after 3 weeks (6 sessions) of active or sham computerized treatment, and participants will be followed for a year to track post-intervention substance use. No medications are involved in this study.
You/your child could be eligible to participate if he or she is:
Between the ages of 16 and 21.
Has or has not used marijuana.
Participants must provide informed consent and youth under 18 must have parental consent to participate.
Compensation is available to those who qualify.
The goal of this study is to determine whether transcranial magnetic stimulation (TMS) is an effective treatment in decreasing craving in individuals who habitually smoke cigarettes. The study consists of six total visits to MUSC; one for the consent process, two that will include MRI scans, and five that will include TMS administration. Compensation will be provided for each visit.
The purpose of this study is to determine whether a scientifically validated treatment for PTSD called Prolonged Exposure (PE) can be delivered effectively to Veterans with Military Sexual Trauma (MST) related PTSD using videoconferencing technology, which allows a therapist and patient who are not in the same room as one another to communicate. We are interested in learning if this form of mental health service delivery is an acceptable alternative to traditional face-to-face therapy delivered with the therapist in the same room as the patient. This study is being conducted at the Charleston VA Medical Center, surrounding Community-Based Outpatient Clinics (CBOCs), and the Medical University of South Carolina (MUSC). It will involve approximately 100 female participants.
Alcohol use disorders (AUD) and intimate partner aggression (IPA) frequently co-occur. There are significant health and economic burdens associated with AUD and co-occurring IPA, and little empirical data to guide treatment efforts. The neuropeptide oxytocin may help mitigate both AUD and IPA. However, clinical data examining oxytocin?s effects on human aggression is scant. The proposed study is designed to address these gaps in the literature by utilizing a human laboratory paradigm to test the effects of oxytocin on craving and aggression among couples with AUD and co-occurring IPA.
This study compares the effectiveness of prolonged exposure therapy, sertraline, and their combination to treat PTSD. Participants receive medication management visits and/or prolonged exposure therapy.
This research taking place at the Ralph H. Johnson VAMC and surrounding Community-Based Outpatient Clinics (CBOCs), specifically the Savannah, Trident, Goose Creek, and Myrtle Beach Clinics. It is for Veterans of Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn (OEF/OIF/OND) who have had combat related posttraumatic stress disorder.
Eligible subjects will receive intranasal oxytocin or placebo (salt water) prior to participating in a stress task. Subjects will be asked about their mood and craving for alcohol. Subjects will also be asked to provide saliva samples for measurement of stress hormones.
The purpose of this study is to develop repetitive transcranial magnetic stimulation (rTMS) as a potential treatment for opiate dependence addiction. Repetitive TMS is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether rTMS over the prefrontal cortex can produce a reduction in your perception of pain, your desire to use opiates, and your brain?s response to opiate cues. TMS has been approved by the FDA as an investigational tool as well a therapy for depression.
The purpose of this study is to study the effects of Yoga on emotions, thinking, and behavior. Participants will attend 10 weekly, 1.5 hour yoga sessions and 2 experimental visits during the course of the study, as well as fill out questionnaires and perform computerized experimental tasks.
Stress is likely involved in relapse to cocaine use. This project will investigate the role oxytocin may play in the stress response in cocaine-dependent men and women and examine how oxytocin may impact brain activity in individuals exposed to cocaine-related cues.
Previous studies suggest that pregnenolone may inhibit the intoxicating effects of marijuana and reduce drug-seeking behavior. In this study we are examining the effects of pregnenolone on craving and mood in response to marijuana cues. In addition we are examing the effects of pregnenolone on blood levels of endogenous endocannabinoids.
