Filter by:The purpose of this research study is to test the effect of repetitive transcranial magnetic stimulation (rTMS) on opioid cravings among adult patients with Opioid Use Disorder.
The investigators propose an imaging study to investigate the neurobiological effects of CBD (vs placebo) in participants with opioid use disorder who are maintained on methadone. The purpose of the study is to determine the neural circuits and transmitters associated with the effects of CBD on to reduce craving and anxiety. The neuroimaging will be conducted in participants immediately following their first administration of CBD (800mg or placebo) and one week after the last administration (3 daily doses). This CBD administration protocol was shown in previous studies by the investigators to reduce craving and anxiety in abstinent heroin users.
The overarching goal of this project is to expand the traditional expertise in non-invasive neuromodulation at the University of Minnesota towards developing novel paired-neuromodulation approaches using transcrancial direct current stimulation (tDCS) for new addiction treatments that support long-term abstinence. This study will investigate whether the pairing of dorsolateral prefrontal cortex (DLPFC) stimulation and cognitive training can enhance functional connectivity between DLPFC and nucleus accumbens (NAcc). We have identified higher functional connectivity between DLPFC and NAcc in alcoholics that have successfully maintained abstinence for extended periods of time (7 years). This paired-neuromodulation approach can potentially be used as a therapeutic intervention to decrease substance use probability in addiction (e.g. opioid use disorder). The long term goal is to develop new addiction treatments that support long-term abstinence in opioid use disorder. The overall objective of this proposal is to enhance functional connectivity between DLPFC and NAcc as a therapeutic intervention to enhance cognition and reduce substance use rates in opioid use disorder.
The study assessed the efficacy of a methadone-induced memory retrieval-extinction procedure on heroin craving and relapse. Male participants aged 18-55 years old and prescribed MMT to treat heroin dependence were included in the present study, and randomly assigned to receive methadone, or receive methadone plus 10 minutes plus extinction, or receive methadone plus 6 hours plus extinction. The intervention persisted 3 times per week for 4 weeks. Then the subjects were followed up once a month for cue induced heroin craving and relapse.
In this study, neuroimaging of reward processing, drug cue reactivity and inhibitory control is used before and immediately after 8 weeks of two types of group therapy in individuals with opioid addiction; clinical outcomes will be assessed before, immediately and three months after treatment. Results could point to factors that track and predict recovery with treatment, offering clinicians markers that can be used for enhancing precision medicine with the goal of reducing morbidity and mortality associated with opiate addiction.
Heroin addiction is a serious problem and the relapse rate of existing treatment methods is extremely high. Recently, international journals such as Science reported that repetitive transcranial magnetic stimulation (rTMS) can reduce the craving of addicts, alleviate depression and anxiety symptoms, and is expected to become an effective treatment. Our preliminary experiment using rTMS to stimulate the left dorsolateral prefrontal cortex of heroin addicts also showed similar effects, however, the mechanism is unclear. Previously, the investigators found that the functional connectivity between left executive control network and default mode network was negatively correlated relapse behavior, while the functional connectivity between salience network and default mode network was positively correlated with relapse behavior. Studies have shown that dopamine dysfunction in addicts and brain metabolism is the biological basis of network connectivity. It suggests that elucidating the relationship between the characteristics of large brain network connectivity and the level of dopamine receptor and relapse behavior in addicts is hopeful to further understand the neurological mechanism of rTMS treatment for addiction. In this project, the investigators intend to observe the changes of brain network connectivity, glucose metabolism and dopamine D2 receptor before and after rTMS treatment in addicts from the perspective of large brain network by combining PET/MRI with psychobehavioral approach. The relationship between rTMS and relapse behavior will be deeply analyzed to provide scientific basis for the development of effective treatment programs.
A case-controlled study is conducted to investigate the effect of adjuvant laser meridian massage in heroin addicts with methadone treatment and establish the model of laser meridian massage treatment for drug addiction.
This study has an experimental design and will examine the difference in pre-test and post-test data on the Self-Forgiveness Dual Process Scale (SFDPS) (Griffin, Worthington, Davis, Hook, & Maguen, 2018) and the Substance Abuse Self-Stigma Scale (SASSS) (Luoma et al., 2013). Data will be collected from two groups of participants receiving counseling at the short-term rehabilitation facility located at University of Pittsburgh Medical Center's (UPMC). Individuals who agree to participate in the study will be randomly assigned to either the experimental group (EG) or the control group (CG). Data collected will include pre-test SFDPS and SASSS scores for the EG and the CG (collected within 24-hours of admission), and post-test SFDPS and SASSS scores for the EG and CG (collected after 14 days). ANCOVA will be used to analyze the pre-test and post-test data recorded from participants' scores.
Heroin dependence is one of most common substance dependence, which brings great burden on health worldwide. Heroin dependence may lead to immunosuppression and cognitive impairments. Once heroin dependence is developed, it will be difficult to recover and easy to relapse. Although many efforts had been made in the treatment of heroin dependence, the annual recurrence of heroin dependence with traditional therapies would be up to 90%. Repetitive transcranial magnetic stimulation (rTMS) on the dorsolateral prefrontal cortex (DLPFC) or cognitive behavioral therapy (CBT) each alone was reported to have some effect on preventing from relapse of substance dependence. In order to test whether combined therapy of high frequency rTMS (hf-rTMS) with CBT is better for preventing from relapse of heroin dependence, we recruit patients with heroin dependence to participate this study. The study is a factorial designed and the patients will be assigned into one of the following six groups randomly: (1) regular treatment (symptomatic treatment) with blank TMS; (2) regular treatment (RT) with blank TMS and CBT; (3) RT with right DLPFC hf-rTMS; (4) RT with right DLPFC hf-rTMS and CBT; (5) RT with left DLPFC hf-rTMS; (6) RT with left DLPFC hf-rTMS and CBT. TMS was given 5 days per week for total 2 weeks using uniform scheme (5 seconds of 10Hz stimulation per train, 30 trains per day with inter-train interval of 20 seconds). CBT will be given once per week for total 8 weeks. The patients will be followed up for 6 months. Recurrence of heroin dependence, duration of abstention, heroin/drug intake, craving for heroin and other cognitive psychological assessments will be recorded and compared among the 6 treatment groups and the efficacy of combined therapy of rTMS with CBT will be evaluated in our study.
A short-term treatment with buprenorphine prior to initiating treatment with naltrexone may increase the proportion of heroin-dependent patients successfully inducted onto Vivitrol.
