Neuroimmune Dysfunction in Alcohol Use Disorder
Alcohol DrinkingAlcohol-Related Disorders14 moreThe objective of this proposal is to advance medication development for alcohol use disorder by examining the efficacy and mechanisms of action of minocycline, a neuroimmune modulator, as a potential treatment. This study has important clinical implications, as the available treatments for alcohol use disorder are only modestly effective and testing novel medications is a high research priority.
An Open-Label Trial of Repetitive Transcranial Magnetic Stimulation for Opioid Use Disorder
Opioid-use DisorderSubstance-Related Disorders2 moreThe purpose of this study is to understand the role of repetitive Transcranial Magnetic Stimulation (rTMS) in reducing opioid and other substance use and craving and improving thinking skills.
Study of the Safety and Feasibility of Psilocybin in Adults With Methamphetamine Use Disorder
Methamphetamine Use DisorderSubstance-Related Disorders3 moreThe purpose of this research study is to investigate the safety and feasibility of two (2) oral doses of psilocybin when combined with behavioral support for methamphetamine use disorder (MUD). Participants have a diagnosis of methamphetamine use disorder (MUD). Participants can expect to be actively engaged in the study for up to 26 weeks.
Study of Structural Imaging
Chemically-Induced DisordersSubstance-Related Disorders3 moreBackground: The way alcohol affects brain structure has been widely studied. But the way it affects all parts of the brain is still unknown. Researchers want to use magnetic resonance imaging (MRI) scans to study brain structure and function. They hope this will help them better understand changes that happen in brain regions during treatment of alcohol use disorders. Objectives: To study changes in the brain by using MRI in people with and without alcohol use disorders. To study how brain changes affect gait, balance, cognitive ability, and behavior. To see how the brain recovers when alcohol use stops. Eligibility: People with alcohol dependence who are currently hospitalized in a particular unit at NIH. Healthy volunteers 30 60 years old without an alcohol use disorder. Design: Participants will be screened under a separate protocol. Participants will give a urine sample for a drug test and pregnancy test at each study visit. They will also have to pass a breath alcohol test. At the first visit, participants will have an MRI. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. They will do behavior and memory tasks outside the scanner. They will have gait and balance tested. They will have to stand on both legs, stand on just one leg, and walk in a straight line. They will perform each task with eyes open, then with eyes closed. They will have tests of memory, thinking, and problem solving. Some participants will have a second visit. They will have another MRI and repeat some of the behavior and memory tasks.
