High levels of brain iron have been found in individuals with cocaine use disorder but the clinical impact of this finding is unknown. The purpose of this research study is to understand if high brain iron in individuals with cocaine use disorder is related to disease severity. We will use non-invasive brain MRI to examine if high brain iron is associated with 1) abnormal brain circuits, and 2) behavioral and cognitive problems. If elevated brain iron is associated with these measures of disease severity, these finding would support a new area of treatment research targeting brain iron in cocaine use disorder.
Many adolescents experience traumatic events, such as child abuse, physical or sexual assault, or witnessing violence. Teens who experience trauma are more likely to have problems with substance use and risky sexual activity. We want to understand how parents can support their teens and help keep them safe after traumatic events.
The project will study how substance abuse and traumatic events are related to how mothers and children respond to rewards, and how they interact with each other. Participating mothers and children will complete tasks in an MRI scanner, questionnaires, and a social behavior task.
Alcohol Use Disorder (AUD) is a risk factor for Alzheimer's Disease (AD), but more research is needed to identify the potential mechanisms underlying this risk. The present study will use fMRI to examine brain network profiles in mid-life AUD. The goal is to develop techniques to assess risk for Alzheimer's Disease and related dementias. Participation includes cognitive testing and MRI scanning.
The purpose of this study is to investigate natural reward processing in cannabis users. Natural reward processing refers to how a person responds to enjoyable or stimulating non-drug experiences. Two groups will participate in the study: 1) people who use cannabis, and 2) people who do not use cannabis. The study will use personalized scripted imagery which involves developing and listening to a detailed story about a personal experience. Scripted imagery has been used to investigate responses to stress and drug experiences and will be used in this study to investigate responses to naturally rewarding experiences.
The purpose of the study is to examine whether an investigational medication called ketamine, which comes in the form of a nasal spray, is able to improve treatment outcomes for concurrent opioid addiction and depression when used in conjunction with buprenorphine treatment. Study medications will be delivered twice per week for four weeks. If you are eligible and you decide to enroll in the study, your participation will last approximately 8 weeks, or 2 months.
The purpose of this study is to determine the effects of a brain stimulation technique known as transcranial direct current stimulation, or tDCS, on the benefits of Prolonged Exposure therapy, or PE, which is an effective treatment for posttraumatic stress disorder, or PTSD. tDCS has been demonstrated to be safe and effective for influencing brain activity by passing a weak electrical current through the scalp. In this study, tDCS is provided in addition to PE treatment, through the National Crime Victim's Research and Treatment Center at MUSC, or the PTSD Clinical Team Clinic within the Ralph H. Johnson VA Medical Center.
The primary purpose of this study is to compare extended-release buprenorphine (CAM2038) to buprenorphine placed under the tongue (sublingual) in pregnant women with opioid use disorder to see if CAM2038 is as effective as sublingual buprenorphine. We are looking to recruit pregnant women who are between 18-41 years old; are between 6-30 weeks pregnant and are not planning to terminate the pregnancy; have opioid use disorder, and are enrolled or are planning to enroll in outpatient buprenorphine treatment at The Medical University of South Carolina. Participation in the study would last between 13 and 21 months total with up to between about 63-102 total visits, including weekly medication check visits and research visits.
This is a 6-week-long treatment study for people with Alcohol Use Disorder who want to stop or cut down their drinking. The purpose of this study is to determine whether an investigational medication, ANS-6637, affects craving for alcohol and/or alcohol drinking while taking the study drug. Participants will be randomly assigned to take one of two doses of ANS-6637 or a matched placebo.
Marijuana is the most commonly used illicit drug. There is high demand for effective interventions for cannabis use disorder, yet few specific treatments for have been developed. This study will evaluate the efficacy of varenicline for reducing marijuana use in people who use marijuana frequently.
