The purpose of this study is to develop repetitive transcranial magnetic stimulation (rTMS) as a potential treatment for opiate dependence addiction. Repetitive TMS is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether rTMS over the prefrontal cortex can produce a reduction in your perception of pain, your desire to use opiates, and your brain?s response to opiate cues. TMS has been approved by the FDA as an investigational tool as well a therapy for depression.
The purpose of this study is to study the effects of Yoga on emotions, thinking, and behavior. Participants will attend 10 weekly, 1.5 hour yoga sessions and 2 experimental visits during the course of the study, as well as fill out questionnaires and perform computerized experimental tasks.
Previous studies suggest that pregnenolone may inhibit the intoxicating effects of marijuana and reduce drug-seeking behavior. In this study we are examining the effects of pregnenolone on craving and mood in response to marijuana cues. In addition we are examing the effects of pregnenolone on blood levels of endogenous endocannabinoids.
Stress is likely involved in relapse to cocaine use. This project will investigate the role oxytocin may play in the stress response in cocaine-dependent men and women and examine how oxytocin may impact brain activity in individuals exposed to cocaine-related cues.
The purpose of this pilot study is to investigate alterations in neural activity among individuals with Tourettes Syndrome. This will be acheived with single-pulse transcranial magnetic stimulation (TMS) and magnetic resonance imaging (MRI). These techniques are non-invasive. TMS is a brain stimulation method that allows us to measure the speed of information processing between brain regions as well as between the brain and the muscles. Combine with MRI, these techniques allow us to create a dynamic image of brain activity which may help guide future treatments. It is important to note that this will be used for research purposes and is not diagnostic.
Major depressive disorder is a common, severe, chronic and often life-threatening illness. It is now the leading cause of disability worldwide. There is a clear need to develop novel and improved therapeutics for treatment-resistant major depression.
Studies with esketamine have shown robust antidepressant effects in several clinical studies and it has been well tolerated in these clinical studies.
The main purpose of this study is to assess the long-term safety, tolerability, and effectiveness of esketamine nasal spray plus a newly initiated oral (taken by mouth) antidepressant in patients with treatment-resistant depression.
All patients in this 60 week study will be treated with esketamine nasal spray plus a new oral anti-depressant. The new oral anti-depressant will be one of the following approved and marketed oral antidepressants: duloxetine (Cymbalta), escitalopram (Lexapro), sertraline (Zoloft), or venlafaxine extended release (Effexor XR).
This study is designed to evaluate the efficacy, safety, and tolerability of ALKS 3831 in schizophrenia with AUD. ALKS 3831 is a combination of olanzapine, an approved antipsychotic treatment for schizophrenia, and samidorphan, a new medication. Potential subjects for this trial are adults with a diagnosis of schizophrenia and alcohol use disorder (AUD) with a recent change in symptoms. The study will test whether olanzapine with samidorphan will aide in lowering alcohol use for subjects at the same time that the combination of the two drugs lessens side effects of olanzapine such as weight gain.
The Sleep Research Data Repository (SRDR) aimed to systematically collect, analyze and store for future research sleep and sleep disorders related biological and psychological information. It will include sleep physiological measurements and the results of interviews, questionnaires, and laboratory tests. The SRDR will contain sleep related information obtained from healthy subjects and patients with psychiatric, substance abuse, neurological disorders, or any medical conditions associated with sleep disturbances. SRDR data will be made available to current and future IRB-approved investigators associated with this protocol.
Currently there is an interest in optimizing rTMS protocols and in particular theta burst stimulation as both a therapeutic and investigational research tool. In a recent publication by Gamboa et al. 2010 it was shown that extended theta-burst stimulation duration (80 seconds) might have reverse effects on cortical excitability when compared to the original Huang et al. 2005 publication (40 seconds). While the post treatment effects of the original Huang et al. 2005 protocol were successfully replicated, when cTBS protocols were doubled to 1200 pulses over 80 seconds and the iTBS protocols were doubled to 1200 pulses over 390 seconds, there was increased facilitation after the prolonged cTBS and decreased excitability after prolonged iTBS. In Hanlon et al. 2015 a novel theta burst paradigm (5 minutes) is described in which two trains of 1800 pulses of cTBS, separated by a one-minute interval. This study aims to replicate the findings of the Gamboa and Huang protocols as well as investigate how novel theta burst stimulation paradigms such as those described in Hanlon et al. 2015, which are currently being explored as therapeutic methods in addiction change cortical excitability.
