The purpose of Project 2 is to execute phase I functional magnetic resonance imaging (fMRI) studies to assess the effects of lorcaserin on brain target engagement (measured by fMRI brain activation and neural connectivity) in cocaine use disorder (CocUD) subjects and/or opioid use disorder.
This phase II pilot study aims at evaluating the benefits and the risks of methylphenidate (Concerta®) for the treatment of cocaine/crack dependence in terms of cocaine/crack use reduction and adverse events.
Repetitive bilateral (left cathodal/ right anodal) transcranial Direct Current Stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) seems to reduce craving and relapse risk. However, little is known about the relapse rates in cocaine addiction after tDCS, despite the need for new treatment interventions to reduce the high relapse rates in cocaine addiction. The investigators aim to explore the effects of repetitive tDCS in a larger sample (N=80) of cocaine addicted patients on number of relapse days after three months. In addition, the underlying working mechanism will be explored (e.g. cognitive control functioning). Ecological momentary assessment (EMA) will be used to measure relapse, craving and mood since retrospective self-reports seem to be less reliable in this respect.
This study evaluates the use of N-acetylcysteine in the treatment of alcohol and cocaine use disorders. Alcohol users will be split in two groups, one will receive the active N-acetylcysteine and the other placebo. The same division will occur with cocaine users. The effects of N-acetylcysteine in adherence, abstinence, psychiatric symptoms and stress biomarkers will be evaluated.
The objective of this study is to evaluate the efficacy and safety of lorcaserin in the treatment of cocaine use disorder.
The objective of this research is to identify the functional neural mechanisms (as assessed using fMRI) of short-term N-acetylcysteine (NAC) administration among methadone-maintained individuals with cocaine dependence.
The purpose of this study is to investigate the short and long term clinical and cognitive effects of repetitive Transcranial Magnetic Stimulation (rTMS) at 5 Hz and/or 10 Hz frequencies on the left dorsolateral prefrontal cortex in cocaine dependent patients and to examine possible changes in brain structure and functional connectivity associated with this intervention.
High relapse rates among substance dependent individuals are likely due to a combination of factors that involve limbic circuits in the brain involved in craving, including vulnerability to salient cues. Emerging data suggests that non-invasive, targeted brain stimulation may be able to modulate activity in these circuits and decrease craving. The primary goal of this pilot study is to determine the extent to which a single session of continuous theta burst stimulation (TBS) to the medial prefrontal cortex can attenuate limbic circuitry involved in craving among cocaine users and alcohol users. This will be tested through a double-blind,sham-controlled brain stimulation and brain imaging study in a cohort of polysubstance abusers and alcohol users.
The purpose of this study is to evaluate whether prednisolone lowers intensity and frequency of craving in heroin-addicted subjects undertaking a detoxification of cocaine and/or heroin.
Background: More effective treatments for people with cocaine use disorder are needed. Researchers want to understand the parts of the brain involved in the disorder. Transcranial magnetic stimulation (TMS) stimulates parts of the brain. A form of TMS called intermittent theta-burst stimulation (iTBS) may help reduce cocaine use. Researchers want to learn how the brain might change with treatment. Objectives: To test if iTBS can reduce cocaine use. Also, to learn how cocaine changes the heart and the brain. Eligibility: Healthy, right-handed adults ages 18-60 who do or do not have cocaine use disorder. Design: Participants will be screened with: - Questionnaires - Medical history - Physical exam - Blood and urine tests - Alcohol breath tests In the pilot study, 10 participants with cocaine use disorder will have 10 treatment days over 2 weeks. Half will be inpatient and half will be outpatient. They will have 2 follow-up visits. Treatment includes: - iTBS: A coil is placed on the head. A brief electrical current passes through the coil. They view cocaine-related images during each session. Sessions are videotaped. - Repeat of screening tests - In the main study, participants will be randomly assigned to have either real or fake iTBS. - Participants with cocaine use disorder will join an incentive program to quit. - Participants will have 39 visits over 6 months. These include: - Repeat of screening tests - MRIs at 5 visits: Participants lie on a table that slides into a cylinder that takes pictures of the brain. They respond to images while in the scanner. - iTBS at 10 visits (5 days a week for 2 weeks) Participants will be contacted throughout the study to discuss iTBS treatment and drug use.
