Filter by:The purpose of this study is to assess the low-intensity focused ultrasound pulsation (LIFUP) neuromodulation on emotion processing in healthy individuals, and to assess the overall safety of the LIFUP to stimulate or inhibit brain activity in healthy volunteers.
This will be a prospective, open-label, single-arm study to determine the safety and feasibility of an intensive treatment of transcranial direct current stimulation (tDCS) for major depressive disorder (MDD). Participants will be age 18-65 with a diagnosis of unipolar MDD. Participants will receive an intensive treatment of tDCS over a 10-day treatment period and complete follow-up assessments at the end of treatment, 1, and 4 weeks post-treatment.
Depression is a leading cause of morbidity and mortality, conferring substantial healthcare and societal costs. By studying methods to non-invasively target neural circuitry involved in reward responsivity, information generated by this project will improve understanding of the circuit alterations that underlie motivation and pleasure deficits in depression, and could also lead to the development of biologically-based markers of neurostimulation-based treatment response.
The purpose of the study is to examine whether an investigational medication called ketamine along with psychotherapy is an effective treatment for depression in participants with a history of opioid addiction who have not abused opioids in at least 3 months. Participants will receive ketamine through intramuscular injection along with psychotherapy weekly for 8 weeks. Participation for eligible subjects who decide to enroll (including post-medication follow-up visits) will last about 16 weeks or 4 months.
Therapeutic latency, lack of efficacy, and adverse drug reactions are the major concerns in current antidepressant therapies. One-third of the patients with major depressive disorder do not respond to conventional antidepressants that act through the monoaminergic system. To overcome these treatment hurdles, add-on therapy to standard antidepressant drugs may lead to better therapeutic outcomes. The recent discovery of the rapid and sustained antidepressant effect of subanesthetic dose of ketamine led to many extensive clinical and preclinical research in the recent past and has established the possibilities of NMDA receptors as a potential drug target for depression. As repeated doses of ketamine are related to abusive potential and adverse effects, the search for a similar antidepressant agent with a better safety profile is essential. Dextromethorphan has the property of noncompetitively blocking N-methyl-D-aspartate receptors (like ketamine) with additional serotonin transporter and norepinephrine transporter inhibitory action. So, the investigators expect that adding dextromethorphan to selective serotonin reuptake inhibitors (SSRIs) regimen can improve clinical outcomes in major depressive disorder. The literature search found that to date, there is no randomized controlled trial on Dextromethorphan as add-on therapy to first-line antidepressants like SSRIs. So, the present randomized controlled trial has been planned to evaluate the efficacy and safety of add-on dextromethorphan to SSRIs in major depressive disorder.
This study is a phase 2/3 open-label controlled trial (CT) in which adults with Major Depressive Disorder (MDD) and adults who have MDD plus comorbid Inflammatory Bowel Syndrome (IBS) will be assigned to either receive oral Fecal Microbiota Transplantation (FMT) or to continue with the treatment they are currently receiving in a Treatment As Usual (TAU) arm. An IBS alone group receiving TAU will be recruited as a clinical control group. The primary goals of this study are to determine effectiveness, safety and tolerability of oral FMT in adults with MDD and in MDD who have comorbid IBS. Additional goals are to characterize patterns and progressions of cognitive and neural correlates associated with MDD and with MDD + IBS and to determine if they improve with FMT. It is known that both, individuals with MDD and those with MDD and IBS show cognitive alterations as well as changes in neural structures, but this study is designed to see if those are changed with treatment response to FMT."
Background: People with TRD are often helped by electroconvulsive therapy (ECT). But ECT can affect memory and thinking. Researchers want to study a treatment called TEST that uses less electricity. Objective: To study the safety and feasibility of TEST and assess its antidepressant effects. Eligibility: Adults aged 25-64 with major depression that has not been relieved by current treatments. Design: Participants will be admitted to the NIH Clinical Center for 5 18 weeks over 2 3 treatment phases. Their medications may be adjusted. Participants will be interviewed about their depression, side effects, and other treatments they are receiving. They will complete questionnaires. They will give blood and urine samples. Their brain waves and heart rhythm will be recorded. They will take tests of memory, attention, mental functioning, and thinking. Participants will have magnetic resonance imaging (MRI) scans of the head and brain. They will lie on a table that slides in and out of the scanner. Pictures of brain chemicals will also be taken. They may complete tasks during the MRI. Participants will receive TEST and/or sham treatments. They may receive optional ECT. An intravenous catheter will be placed in an arm vein to receive general anesthesia. Two electrodes will be placed on the front of their head. An electric current will be passed from the ECT machine through the electrodes. For sham treatments, they will not receive the electric current. Their breathing, heart rate, brain function, blood pressure, and body movements will be measured. Participants will have 7 follow-up visits over 6 months. Visits can be done via telehealth. Participation will last for up to 42 weeks.
To evaluate the efficacy of NBI-1065846 compared with placebo on improving symptoms of anhedonia in participants with major depressive disorder (MDD).
The purpose of this study is to collect biologically-based data for defining predictors and correlates of the effects of ALTO-300.
Depression is a debilitating psychiatric disorder with a recurrent and progressive course. Around 25% of depressive patients has experienced moderate to severe levels of childhood trauma (CT), resulting in earlier onset and more severe and recurrent depressions. There is currently no targeted treatment for CT-related depression. This is problematic as patients with CT-related depression respond poorly to standard depression treatments. The RESET-psychotherapy study proposes an innovative, targeted disease-modifying treatment strategy for CT-related depression. The main objective is to investigate the effectiveness of trauma-focused therapy (TFT), as an addition to regular depression treatment ('treatment as usual'; TAU), in reducing depression symptom severity in patients with CT-related depression. 158 adult patients will be randomized to receive a 12-week treatment with 1) TAU or 2) TFT in combination with TAU. The primary outcome measure is defined as depression symptom severity after 12 weeks treatment (post-treatment), measured with the Inventory of Depressive Symptomatology - Self Rated (IDS-SR).
