Filter by:This study is using Transcranial Magnetic Stimulation (TMS) to determine if interventional psychiatry treatment can help with the treatment of Methamphetamine Use Disorder. Individuals with Methamphetamine Use Disorder will receive 5 consecutive TMS treatment sessions based off of randomization. Participants will be randomized to one of two groups. TMS treatment arm or sham-TMS arm.
The purpose of this Phase 1a study is to evaluate safety, tolerability, and pharmacokinetics (PK) of single, ascending doses of CS-1103, administered by intravenous (IV) infusion in healthy participants.
1. To evaluate the cognitive function of methamphetamine Patients. 2. Investigate the pathological mechanism of methamphetamine patients from the aspects of EEG and biology; 3. The investigators investigated the effects of transcranial alternating current stimulation (tACS) on cognitive impairments in methamphetamine patients
The goal of this clinical trial is to learn if administering a high dose stimulant with Contingency Management reduces days of use in adults who use methamphetamine better than the usual treatment provided by the clinic. The main questions the trial aims to answer are: Is a high dose stimulant better than a placebo and usual treatment at helping reduce the number of days they use methamphetamine? Is a high dose stimulant with contingency management better than placebo and usual treatment at helping people reduce the number of days they use methamphetamine? Participants will be placed randomly into one of four groups: 1. Usual treatment and placebo 2. Usual treatment, placebo and contingency management 3. Usual treatment and high dose stimulant 4. Usual treatment, high dose stimulant and contingency management Participation includes the following: 1. Participants will receive medication or placebo weekly for 15 weeks. 2. Participants will attend the clinic for weekly treatment 3. Participants will attend the clinic once every 2 weeks for study visits. Each visit will take about an hour to complete. At these visits, participants will be asked to provide a urine sample and complete questionnaires.
The main goal of this study is to tests the effect of incentivizing achievement of self-identified, personal harm reduction goals (Contingency management or CM) compared with standard of care (peer harm reduction service with incentives for peer visits) to increase the reach and effectiveness of methamphetamine (MA) harm reduction services.
The OVERALL AIM is to assess whether app-based incentives are effective for older adults and to quantify the associations between age and both the efficacy and take-up of app-based incentives. This will allow us to determine if older adults with substance use disorders (SUDs) are willing to engage with app-based incentives and whether they perform similarly to their younger counterparts. Because the study will leverage data from an existing study on app-based incentives, a small add-on study is sufficient to address these three aims. This aim will be achieved while simultaneously gathering data that will shed light on the two aims of the first phase of the study: whether app-based incentives are effective overall, and how to optimize the size of incentives over time to maximize their effectiveness.
Combatting the rise of the opioid epidemic is a central challenge of U.S. health care policy. A promising approach for improving welfare and decreasing medical costs of people with substance abuse disorders is offering incentive payments for healthy behaviors. This approach, broadly known as "contingency management" in the medical literature, has repeatedly shown to be effective in treating substance abuse. However, the use of incentives by treatment facilities remains extremely low. Furthermore, it is not well understood how to design optimal incentives to treat opioid abuse. This project will conduct a randomized evaluation of two types of dynamically adjusting incentive schedules for people with opioid use disorders or cocaine use disorders: "escalating" schedules where incentive amounts increase with success to increase incentive power, and "de-escalating" schedules where incentive amounts decrease with success to improve incentive targeting. Both schemes are implemented with a novel "turnkey" mobile application, making them uniquely low-cost, low-hassle, and scalable. Effects will be measured on abstinence outcomes, including longest duration of abstinence and the percentage of negative drug tests. In combination with survey data, variation from the experiment will shed light on the barriers to abstinence more broadly and inform the understanding of optimal incentive design.
Methamphetamine (MA) is one of the commonly used drugs during pregnancy. Cardiovascular effects of MA include elevated blood pressure, acute vasospasm, atherosclerotic disease, structural and electrical remodeling of cardiac tissue leading to arrhythmias and heart failure, and pulmonary hypertension.1 In addition, MA can cause neurotoxicity with harmful effects on neurodevelopment in the children who had prenatal exposure.5-8 Currently neonatal providers do not perform detailed cardiovascular evaluation in newborn period or long term neurodevelopmental assessments as outpatient for the newly born infants with prenatal exposure to MA, and they do not qualify for early intervention. The goal of the investigators is to perform detailed cardiovascular evaluation in neonatal period and estimate baseline prevalences and follow up with developmental and cardiovascular assessment using a questionnaire at 12 months in a cohort of neonates enriched with those who had prenatal exposure to MA.
The primary aim of this project is to use a randomized single-blind sham-controlled study to investigate if high frequency repetitive transmagnetic stimulation (HF-rTMS) can modulate cue-induced craving in adult methamphetamine (METH) users. The investigators hypothesize that HF-rTMS directed at left dorsolateral prefrontal cortex (DLPFC) will result in a reduction in craving for METH compared to sham-controlled rTMS in adults with methamphetamine use disorder (MUD) as evidenced by validated measures of METH craving. Neurobiologically, the investigators anticipate rTMS mediated stimulation of the DLPFC could result in inhibition of cue-induced craving through potential disruption of involved circuitry. The current project proposes that participants who are recently abstinent from METH will be randomized into four experimental groups to provide two rTMS conditions (real versus sham) and two picture cues conditions (METH versus neutral). The experiment will have an induction phase where each subject will receive 10 daily treatments within 2 weeks. Just before each rTMS/sham session participants will be shown visual cues (METH or neutral). Participants will then undergo a maintenance phase for an additional month with assessments to evaluate craving and relapse. Urine samples for urine drug screening (UDS) will be collected at screening day and on days 1, 5 and 10. Just before each rTMS/sham session participants will be shown visual cues (METH and neutral). VAS craving scores will be assessed before and after picture presentation and after the rTMS/sham session. Before the first and 10th treatment session, participants were evaluated by the the Stimulant Craving Questionnaire (STCQ) and the Severity of Dependence Scale (SDS) questionnaires. Participants will then undergo a maintenance phase for an additional month. During the first week of maintenance, three rTMS/sham sessions will be administered. During each of the following 3 weeks, one rTMS/sham session will be given per week. As with the induction phase, urine samples will be collected for screening and STCQ and the SDS questionnaires will be completed at each maintenance session. To evaluate the long-term effects of the rTMS treatment, the investigators plan on contacting participants 6 months after treatment termination for all subjects who completed the 10 treatment sessions. During that phone conversation, craving and relapse will again be assessed.
