Neuromodulation of Executive Control for Substance Use Disorders
TACS fMRI (NEC-TACS)
The purpose of this research study is to determine the effectiveness of a procedure called transcranial alternating current stimulation (tACS) using a device called StarStim cap and its effects on drug cravings.
研究概览
详细说明
Participants will undergo a 1-2-day screening that includes a urine drug screen, clinical interview, and self-reporting assessments, once screening is complete, participants will complete a (EEG) recording of your brainwaves. The EEG recording and electrode placement will take about 2 hours. The next portion of the study will involve the use of the StarStim device and an MRI, and you will be asked a series of questions while wearing the device. The day after the MRI scan you will receive a short phone call from study staff. You will be asked to participate in study visits for 2 or 3 days and have 1 follow-up visit. Total study duration for this research study is up to 2 weeks.
The electrical stimulation that the StarStim device uses is considered to be safe, and we are not anticipating any serious side effects. However, mild side effects could include headache, itching and tingling. There are additional risks involved with MRI scans.
You may not receive any personal benefits from being in this study. We hope the information learned from this study will benefit other people with similar conditions in the future.

描述
Inclusion Criteria:
- Able to provide written consent and comply with study procedures.
- Adults aged 18 to 65 years at the time of consent.
- Meets the MINI diagnostic criteria for either methamphetamine use disorder (MUD).
Exclusion Criteria:
- Any contraindications for tACS or MRI scanning (tACS contraindication: history of seizures; potential MRI contraindications, up to the discretion of AIRC and CBH staff: metal implants, pacemakers or any other implanted electrical device, injury with metal, braces, dental implants, non-removable body piercings, pregnancy, breathing or moving disorder).
- Any medical condition or treatment with neurological sequelae (i.e., stroke, tumor).
- Over 9 months of abstinence from substance use.
- A head injury resulting in a loss of consciousness exceeding 30 minutes (i.e., moderate or severe TBI).
- Presence of a condition that would render study measures difficult or impossible to administer or interpret.
- Entrance to the treatment program under a court mandate. (i.e. legally incarcerated).
- History of ECT or cortical energy exposure within the past 6 months, including participation in any other neuromodulation studies.

实验性的：Arm 1: Active intervention- tES (transcranial electrical stimulation), then Sham Intervention
tES is considered to be a safe brain stimulation technique that rarely results in adverse events. There is currently no evidence of serious side-effects. Mild side-effects that typically resolve upon discontinuing tACS. The subject may choose to discontinue stimulation at any time during the session if experiencing excessive discomfort or side effects. |
This study involves the use of an investigational device called StarStim. "Investigational" means that the device has not yet been approved by the U.S. Food & Drug Administration (FDA) for helping people recover from drug addiction. This study will help find out what effects, good and/or bad, this device has. The safety of this device in humans has been tested in prior research studies; however, some side effects may not yet be known comparator arm |

Task-dependent functional connectivity measured using psychophysiological interaction (PPI) analysis of blood oxygen level-dependent (BOLD) functional MRI data. PPI regression coefficients quantify differences in connectivity during drug-related versus neutral cues within the executive control network, including the dorsolateral prefrontal cortex and inferior parietal cortex, and between executive control regions and limbic regions, including the ventral striatum and amygdala. Connection-specific PPI coefficients will be reported separately, with within-participant comparisons between active in-phase, active anti-phase, and sham tACS conditions. |
