The Effects of Theta Burst Stimulation on the Brain Response to Drug and Alcohol Cues (addictionTBS)
Alcoholism, Cocaine Addiction, Drug Addiction
About this trial
This is an interventional basic science trial for Alcoholism focused on measuring Transcranial Magnetic Stimulation, Magnetic Resonance Imaging, MRI, Functional
Eligibility Criteria
Inclusion Criteria:
- Age 25-55
- Non-treatment seeking cocaine users (with or without comorbid alcohol use disorder)
- Current alcohol use greater than 20 standard drinks per week
- Current DSM-V Alcohol Use Disorder diagnosis, including the loss of control item
- Currently not engaged in, and do not want treatment for, alcohol related problems
- Able to read and understand questionnaires and informed consent
- Lives within 50 miles of the study site
Exclusion Criteria [These are listed in greater detail in the CIA Core]:
- Any current DSM-V Axis I diagnosis except Alcohol, Cocaine, or Nicotine Use Disorder
- Current or past substance dependence criteria other than cocaine, marijuana, or alcohol, smoking >1 pack of cigarettes per day
- Current use of any psychoactive substance except cocaine, nicotine, and marijuana or medications as evidenced by self-report or urine drug screen
- Current breath alcohol concentration >0.002
- Positive urine drug screen for stimulants (including cocaine, amphetamine, methamphetamine, etc.) at the Scanning/Stimulation visits and signs of alcohol withdrawal. Based on the sensitivity of this test, this will require that the participants abstain from cocaine use for 48 hours prior to the intervention
- History of seizures or migraine headaches
- History of head trauma or epilepsy
- Violation of other magnetic resonance imaging safety measures
- Current suicidal or homicidal ideation
- Presence of ferrous metal in the body, as evidenced by metal screening and self-report
- Severe claustrophobia or extreme obesity that preclude placement in the MRI scanner
- For female participants, pregnancy, as evidenced by a urine pregnancy test administered on the day of the scanning session
Sites / Locations
- Medical University of South Carolina
