Alcohol misuse is a risk factor for early onset cognitive impairment, contributing to 10% of early onset dementia, with risk corresponding to consumption. Additionally, continued drinking risks worsening cognitive decline and dementia progression, while worsening cognitive impairment contributes to drinking escalation. Repetitive transcranial magnetic stimulation (rTMS) has been shown to improve cognition in Alzheimer's Disease and Related Dimentias (ADRD) and separately reduce heavy drinking in alcohol use disorder. Our objective is to optimize rTMS for simultaneous mitigation of both drinking and cognitive dysfunction in older adults.

By doing this study, we hope to learn if a brief screening method can predict which people are most likely to show a positive response to selective serotonin reuptake inhibitor (SSRI) medications. This brief screening method involves using electrodes attached to your scalp via a cap, to measure electrical brain activity in response to a series of loud tones.
Your participation in this research will last about 17-21 weeks if you decide to stay for the whole study.

This study will examine how marijuana use can affect oral bacteria and brain health in people with HIV and without HIV. Early studies show that marijuana users have more oral bacteria than non-marijuana users. The increase in bacteria is believed to affect brain health. Participation in the study will be one visit. The visit will take approximately 120 minutes.

The purpose of the study is to compare a text message based mental health and substance use screening and referral to treatment program, called Listening to Women and Pregnant and Postpartum People (LTWP), to standard of care in-person mental health and substance use screening to look at rates of treatment attendance and retention in treatment. Participation would involve completing online surveys. You may be eligible to participate if you are age 18-45 years, are pregnant and entering prenatal care in one of MUSC's OB clinics, and attended a prenatal appointment at an MUSC clinic.

This study is testing cannabidiol (CBD) as a possible medication to treat alcohol use disorder. Youth (ages 16-22) will receive one dose of CBD (600mg) or placebo (i.e., sugar water) before two different MRI sessions (separated by 2 weeks) to see how CBD affects the brain. The full study will last approximately one month.

Participants must provide informed consent and youth under 18 must have parental consent to participate.

Compensation is available to those who qualify.

This research study evaluates the effects of anFDA-approved medication Gabapentin in individuals with Bipolar Disorder who smoke marijuana. Participants in the study will will be assigned to take either Gabapentin or a matched placebo. Study medication will be taken for 17 days. There will be 5 study visits, with 2 MRI brain imaging scans completed. Questionnaires and clinical interview measures will be completed at study visits along with consistent assessment of potential side effects from study medication.

Adults (ages 18+) who would like to reduce their cannabis use (N=224) will be enrolled in an 8-week treatment program. All participants will receive counseling (1 goals session with a therapist followed by 7 weekly computerized cognitive-behavioral therapy sessions). Detailed cannabis assessments (biological and self-report) will be conducted throughout treatment and at 1-, 2-, and 3-months post-treatment completion. Daily electronic diaries will be administered via text message to record detailed logs of cannabis use quantity and frequency. Salivary samples will be collected (and video observed) daily throughout treatment to analyze for progesterone.

The purpose(s) of the research is to test a new medication in combination with a talk therapy for Veterans experiencing posttraumatic stress disorder (PTSD) and who may have alcohol use disorder (AUD). The study consists of 12 weekly therapy sessions. Once per week before each therapy session, an intranasal dose of investigational medication will be administered. The study also involves 3 and 6-month follow-up appointments and the administration of questionnaires at each visit.
