Transcranial Magnetic Stimulation for Treatment of Methamphetamine Use Disorder

September 13, 2021 updated by: Shanghai Mental Health Center

Evaluation of the Effect of Repetitive Transcranial Magnetic Stimulation in Craving in Methamphetamine Use Disorder

Repetitive transcranial magnetic stimulation (rTMS) was used to treat methamphetamine use disorder in previous studies, while the evidence-based protocols still required. The aim of this research is to develop more applicable rTMS intervention pattern and protocols to reduce craving and relapse of methamphetamine-dependent patients.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The limbic circuit and executive control circuit are two important frontal-striatal neural circuits associated with drug dependence. Previous studies showed increased functional activity within the limbic neural circuit (e.g. medial prefrontal cortex (mPFC) and ventral striatum) in the presence of a salient cue and decreased activity in the executive control circuit (e.g. dorsal prefrontal cortex and dorsal striatum). TMS was used to reverse the activities of these two circuits, by using continuous TBS and intermittent TBS, respectively. In this study, vmPFC cTBS was conducted to modulating the limbic circuit, while left dlPFC iTBS was conducted to modulating the executive control circuit. Combined treatment of vmPFC cTBS and left dlPFC iTBS was conducted to modulating two circuits simultaneously. Focused on evaluating the efficacy of the interventions and investigate the mechanisms, neuropsychological tests, biochemical tests, and electroencephalography will be used to investigate the neurobiological mechanism of the methamphetamine use disorder, craving, and relapse. The study will be very helpful to develop evidence-based rTMS protocols for methamphetamine-dependent patients in clinical practice and decrease harm for both the patients and their families.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating).
