Filter by:Using specific EEG biomarkers in methamphetamine-dependent individuals, this study systematically probes closed-loop tACS based on brain states, assessing dosage, neurologic and behavioral effects, while comparing its efficacy with traditional open-loop tACS methods.
Chronic drug addiction is not only associated with increased mental health symptoms, such as anxiety and depression, but also with brain (neural and cognitive) deficits. These neurocognitive deficits (NCDs) in memory, attention, decision-making, self-control and judgement disturb normal daily functioning and attempts for abstinence. These NCDs are also associated with worse long-term treatment outcomes. Current treatment programs for addiction to opioids and amphetamines are mainly focused on abstinence from illicit drugs with or without assistance of medications, with the assumption that these NCDs will subsequently heal. However, NCDs are found to persist even after a long-term abstinence and are thought to contribute to relapse, decreases quality of life, or lack of reintegration into society. Furthermore, NCDs (particularly related to attention and memory) are considered a potential obstacle for engagement in therapy services for addiction and associated mood, anxiety and trauma-related comorbidities (i.e., cognitive-behavioral therapies). Brain rehabilitation programs focused on compensatory strategies and training exercises for NCDs associated with traumatic brain injuries, stroke, multiple sclerosis and schizophrenia has consistently been found to improve functioning and long-term outcomes for these populations. There have been a few preliminary attempts to transplant cognitive rehabilitation with substance use populations, with some limited promise. However, these previous studies failed to link cognitive strategies with the drug use and affective/craving symptoms experienced by patients and also did not fully incorporate knowledge gained from neuroscientific research on opioid and/or methamphetamine addiction specifically. The aim of this study is to characterize clinical efficacy for an intervention targeting NCDs in opioid and/or methamphetamine addiction by enhancing awareness and use of neurocognitive skills in the context of substance use recovery. This aim will be accomplished by randomizing 80 subjects with opioid and/or methamphetamine use disorder who are already enrolled in substance use treatment in the state of Oklahoma to also complete a novel "Neurocognitive Empowerment for Addiction Treatment" (NEAT) program developed by a group of investigators at Laureate Institute for Brain Research, Tulsa, Oklahoma. NEAT will be novel in (a) its use of cartoons, brain awareness games and real-life scenarios to ensure it is interactive and engaging, (b) the focus on the role of neurocognitive deficits in recovery from substance use and co-occurring mental health symptomatology, and (c) its incorporation of neuroscientific findings specific to substance use to the training and exercise strategies. Subjects will be followed up for twelve months after starting the program with different measures for addiction and mental health recovery to explore the efficacy of NEAT compared to the control intervention. Using LIBR's cutting-edge neuroimaging facilities before and after interventions, this study has the unique opportunity to monitor not only clinical outcomes but also potential changes NEAT may have on brain structure and function. In case of finding reasonable clinical efficacy for NEAT, it will be hopefully integrated as a manualized brain rehabilitation program to the substance use treatment programs.
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.
Methamphetamine use disorder (MUD) is among the costliest and deadliest substance use disorders (SUDs) world-wide and is frequently comorbid with other mental health conditions. There is no empirically validated medical treatment for MUD. Drug craving is the signature aspect of MUD and other substance use disorders and has been associated with continued drug use and relapse. The investigators and others have shown that transcranial direct current stimulation (tDCS) over dorsolateral prefrontal cortex (DLPFC) can modulate drug craving in different SUDs. tDCS is a method of non-invasive brain stimulation and is a low-cost scalable technology without any serious side effects that delivers low levels of direct current (0.1-2 mAmp) transcranially. However, there are significant inter-individual differences in response to tDCS, which is not well understood but can have profound impact on efficacy. Meanwhile, there are no studies with neuroimaging to show how tDCS affects drug craving. Investigators propose the first combined tDCS/functional Magnetic Resonance Imaging (fMRI) study to examine the acute effects of tDCS on neural substrates underlying drug induced craving.
The purpose of this pilot study is to determine the tolerability, feasibility, and preliminary effectiveness of intranasal oxytocin administration prior to motivational enhancement group therapy sessions on laboratory-based measures of addiction, social connectedness, and stress responsivity in methamphetamine(meth)-using men who have sex with men (MSM). The investigators propose a randomized, double-blind, study of intranasal oxytocin versus placebo 40 IU prior to each of six Motivational Interviewing Group Therapy (MIGT) sessions in 28 mixed HIV sero-status MSM initiating treatment for amphetamine use disorder.
