The study will use a new method for non-invasively examining the brain called Transcranial Magnetic Stimulation (TMS). TMS involves placing a coil of wire above the scalp and intermittently passing a very powerful current through it. This current produces energy in the form of a magnetic field that passes through the scalp. The magnetic field, in turn, induces a much weaker electrical current in the brain, causing the neurons directly under the coil to activate for a brief period of time. The U.S. Federal Drug Administration has approved TMS as a method for treating depression since 2008. By using TMS, we can evaluate how well your brain is controlling one of your hand or leg muscles. One way to measure this is by recording activity via electrodes on the hand opposite the side of the brain being stimulated. For example we will be stimulating on the left side of the brain and recording from electrodes on your right hand. In this study we are determining the effects of different types of repetitive Transcranial Magnetic Stimulation (rTMS) protocols on hand movement. rTMS means that the magnetic pulses are applied consecutively, and at a specified pace- the frequency. The specific type of rTMS you will receive is called "theta-burst stimulation" (TBS). TBS is characterized by a specific frequency of stimulation.
Objectives: The aim of the study is to evaluate the efficacy and safety of DTMS for the treatment of PTSD.
Patient Population: 176 male and female subjects, 22-68 years of age, currently diagnosed with PTSD according to the DSM-V criteria.
Structure: A randomized, controlled, prospective, 9 week, double blind, multicenter study.
Blinding: The treatment administrator, study rater, all study personnel and patients will be blinded to the treatment being administered.
Concurrent Control: The study group will receive active DTMS treatment and the control group will receive inactive, sham treatment.
The purpose of this study is to determine if there are any differences in the improvement of MDD and PTSD symptoms when using two different types of ECT, and also to determine what effect recalling two different memories (a positive memory or negative PTSD memory) just prior to receiving ECT may have on PTSD symptoms. The two types of ECT treatment to be used in this study are called right unilateral ultrabrief (RUL UB) ECT and bilateral brief pulse (BL BP) ECT. Both types of ECT are widely used in the treatment of depression and are commonly used when ECT is recommended. This study will involve 70 (35 local and 35 at Long Beach VA site) subjects who are veterans suffering from MDD and PTSD.
This study examines the effects of the medication gabapentin and the supplement n-acetylcysteine among individuals with Bipolar Disorder who regularly drink alcohol. Participants in this study will take gabapentin, n-acetylcysteine, and matched placebo (one at a time) for 5 days each. There are 8 study visits, including 3 MRI scans.
This study is designed to evaluate the safety and effectiveness of using two different medications (extended release naltrexone and bupropion) compared to matching placebo (an inactive substance) in the treatment of methamphetamine use disorder. Participants will receive study medications along with brief medication management for twelve weeks, with follow up visits at weeks 13 and 16.
Recent research suggests that a new kind of treatment, repetitive transcranial magnetic stimulation (rTMS) can help people with substance use disorders cut down or quit using. This study seeks to recruit individuals who are currently heavy marijuana users who are attempting to cut down or quit using marijuana. Participants will have 20 treatments of active or sham rTMS over 10 visits. In addition to having a 50% chance of receiving rTMS, participants will be given behavioral counseling. Participants who received sham rTMS will have the opportunity to receive active rTMS after they complete the study.
PROJECT SUMMARY Chronic use of opiates is a rapidly escalating crisis in the United States, with over 4.3 million Americans dependent on opiate analgesic, an escalating rate of opiate overdose deaths, and a resurgence of intravenous heroin use leading to total societal cost exceeding $55 billion. The struggle to break the addiction cycle is likely due to factors that affect neural circuits that govern craving and cognitive control. There is growing interest in the utilization of prefrontal cortex repetitive transcranial magnetic stimulation (rTMS) as a novel, non-invasive, non-pharmacologic approach to decreasing craving among chronic opiate users. At this early stage of development, however, it is unclear if the best TMS strategy is to (Strategy 1, Aim 1) increase activity in the dorsolateral prefrontal cortex, or (Strategy 2, Aim 2) decrease activity in the ventromedial prefrontal cortex. To parametrically evaluate these two promising treatment strategies, we have developed a three-visit crossover design wherein a cohort of buprenorphine-maintained (as a therapeutic technique to address opiate dependence) opiate dependent individuals will receive interleaved TMS/BOLD imaging and our established MRI-based thermal pain paradigm immediately before and after rTMS. We will also measure subjective pain and opiate craving ratings. The relative efficacy of Strategy 1 vs 2 will directly translate to development of a large clinical trial of rTMS as an innovative, new treatment option for pain in opiate dependent individuals.
This study aims to conduct focus groups with adolescents and parents (30 adolescents and 30 parents) to gather feedback to help design an integrated psychological therapy for co-occurring PTSD and substance use among adolescents (Teen COPE). This information will be used to make revisions to the new Teen COPE Therapist Guide and Patient Workbook.
This study will examine the effect of N-Acetylcysteine (NAC), an over-the-counter antioxidant supplement on brains of youth (ages 15-19) using magnetic resonance imaging (MRI). 55 adolescents will receive, in a counterbalanced order, a 10-day course of NAC 1200 mg twice daily and a subsequent 10-day course of matched placebo twice daily, separated by 11 days. Urine samples will be collected at screening and urine and blood samples will be collected before and after each course of medication treatment. Participants will receive a 1- hour MRI scan at baseline and after each treatment trial.
You/your child could be eligible to participate if he or she is:
Between the ages of 15 and 19.
May or may not drink alcohol.
Participants must provide informed consent and youth under 18 must have parental consent to participate.
Compensation is available to those who qualify.
We will study healthy adults with a brain stimulation tool (TMS) either inside or outside of the MRI scanner, and test with EEG whether it matters where we place the TMS coil on the head. The TMS induced changes in EEG have been proposed as a surrogate measure of brain connectedness, which changes greatly when we are conscious and when we are not.
