NCT03026309
Main objectives: Comparing levels of F-DOPA reuptake rate as an indicator for Dopamine metabolism of un-medicated Depressed patients to healthy individuals in the Mesocorticolimbic System (VTA-NAc-PFC) and assessing structural differences between the two groups in the Hippocampus, Hypothalamic-Pituitary gland and Mesocorticolimbic System (VTA-NAc-PFC) and resting state fMRI. Secondary objectives: 1. Comparing the differences of DNA Methylation in the plasma and serum of patients compared to healthy controls. 2.Assessing the correlation between symptoms' severity score (evaluated based on Hamilton Rating Scale) at base line and 6 months following treatmnt to PET 18F-DOPA uptake repertoire in the Mesocorticolimbic System, structural measurements and DNA Methylation. Methodology: Study Design: A prospective, pilot study. 30 un medicated Depressed patients and 30 Healthy volunteers will perform a \[18F\] FDOPA PET/MRI scans following a HAM-D questionnaire (Hamilton rating scale of depression) and blood tests. PET-MR (Biograph mMR, Siemens AG, Erlangen, Germany) scans will be performed using the tracer of dopamine precursor 3,4-dihydroxy-6-\[18F\]-fluoro-l-phenylalanine (\[18F\] FDOPA) that reflects L-dopa transport, L-aromatic amino acid decarboxylase activity, vesicular uptake and the number of dopamine nerve terminals. Measurements of dynamic F-DOPA parameters (Ki) and quantitative measurements of static F-DOPA ( SUVmax and SUVmean) will be performed in the ventral tagmental area (VTA), nucleus accombens (NAc) and pre-frontal cortex (PFC)which comprise the Mesocorticolimbic System, bilaterally. MRI sequences of T1, T2 3D measurements (assessing Volume) of the hippocampus, Hypothalamic-Pituitary gland and Mesocorticolimbic system, DTI measurements in the mesocorticolimbic dopaminergic tract and BOLD (resting-state f-MRI) in those brain networks. whole genome DNA Methylation from whole blood will be performed. To date there is no quantative standard of care evaluation tool that serves psychiatrists when assigning medication for newly diagnosed depressed patients. The manner in which medications are assigned are threw symptom evaluation and trial and error. Only a third of the patients achieve remission after the first line of treatment. SSRI's are most common type of medication used to treat Major Depression today. One third of patients remains un responsive even after the fourth line of treatment (of different types of medications). Anti depression medications way of action requires time to reach its effect and in many patients with no avail or even causing symptom's severity. The PET-MR multimodality imaging tool offers a cutting edge technology ideally fitted to measure brain disorders. The use of F-DOPA radio-ligand with the PET-MR constitutes a novelty in the imaging of the depressed brain. Dopamine is one of three of the monoamine neurotransmitters targeted by anti-depressive medication, sharing metabolistic agents. dopamine has been proven to be connected to the processing of emotion, motivation, hedonism and reward threw its action in the Meso-cortico-limbic system. Epigenetics is a regulatory system that determines gene expression. It is heritable in the one hand and reacts to environmental changes on the other. It has been shown to be involved in psychiatric disorders. PET-MR scans will be performed. DNA samples will be extracted from subject's whole blood samples taken prior to scans. Then it will be analyzed for whole genome DNA methylation. Taken together this novelty imaging technique and epigenetic mapping of peripheral markers can be used to better understand and personalize anti-depressive treatment compatibility.
NCT01210651
This was a randomized controlled pilot trial to evaluate clinical efficacy and feasibility of hatha yoga as a mono-therapy for major depression. Investigators recruited 38 adults in San Francisco meeting criteria for major depression of mild-to-moderate severity, per structured psychiatric interview and scores of 14-28 on Beck Depression Inventory-II (BDI). At screening, individuals engaged in psychotherapy, antidepressant pharmacotherapy, herbal/nutraceutical mood therapies, or mind-body practices were excluded. Twenty participants were randomized to 90-minute hatha yoga practice groups twice weekly for 8 weeks. Eighteen participants were randomized to 90-minute attention control education groups twice weekly for 8 weeks. Certified yoga instructors delivered both interventions at a university clinic. Primary outcome was depression severity, measured by BDI scores every 2 weeks from intervention start at 0 weeks until finish at 8 weeks. Secondary outcomes were self-efficacy and self-esteem, measured by scores on the General Self-Efficacy Scale (GSES) and Rosenberg Self-Esteem Scale (RSES) at 0 weeks and 8 weeks. Blinded assessors analyzed whether change in outcome measures would be statistically comparable between the two intervention groups.
NCT02014363
To demonstrate that the antidepressant activity of ETS6103 is not inferior to amitriptyline in subjects who have an unsatisfactory response to / are resistant to treatment with SSRIs.
NCT02176473
In an open-label feasibility study, fifteen will be recruited to participate in the study from among those who have already chosen of their own accord to undergo ECT (standard of care) at Yale Psychiatric Hospital for treatment of a depressive episode. These patients will receive computer-assisted cognitive behavior therapy (CCBT).
NCT01999010
Mood journaling is a cornerstone of self-management in major depressive disorder (MDD). Research over the last decade has shown that electronic mood journals are superior to paper ones. One potential advantage of mental health telemetry (MHT), which use cell phones to collect mood journal data, is that electronic journal data can easily be converted into graphical records, allowing people living with MDD to readily spot trends, correlations, or patterns in ways that would be quite challenging using paper diaries. This information should make it easier to recognize and evaluate changes in mental health status -- the first two steps in the process of self-management. The investigators will develop and deploy a visualization module for patients with which to explore their own MHT data sets on the same cell phones which they record their journals, and test the investigators hypotheses that their enhanced MHT system will (i) improve patients' ability to self-manage MDD and (ii) enhance their quality-of-life. The study is a non-randomized, un-blinded, A-B-A' (modified single-subject withdrawal design, with user choice of treatment or withdrawal in the A' stage) study, to explore the utility of MHT as a tool for enhancing self-management and QoL for persons living with MDD. The aims of this study are to explore the impact of MHT on subjects' self-management and QoL, and to gauge participants' perceptions of MHT's utility.

The purpose of this study is to assess the effect of treatment with Advair Diskus on depression using the Cornell depression scale in COPD patients in the nursing home.
NCT00056303
This study will determine the effectiveness of a relationship-based intervention in improving the interaction between caregivers and young children placed in their care.
NCT01822197
The purpose of this study is to determine whether bright light phototherapy can improve depressive symptoms in hospitalized patients with cystic fibrosis (CF) with subsequent effects on quality of life and illness recovery. It is hypothesized that phototherapy will improve depressive symptoms and decrease length of stay in depressed patients with CF who are hospitalized.
NCT01403662
Long-term studies have emphasized that depressive symptoms and episodes account for majority of the illness burden experienced by individuals with bipolar disorder (BD). Previous studies have shown that blood levels of proteins called pro-inflammatory cytokines are abnormal in individuals with bipolar depression. The investigators hypothesize that preventing the production or release of pro-inflammatory cytokines will result in improvement of depressive symptoms in individuals with bipolar depression. Minocycline is a medication that inhibits the activation of immune cells (i.e. microglia) in the brain and reduces the production of pro-inflammatory cytokines. Treatment with minocycline has been shown to have antidepressant-like effects in animal studies and improve symptoms of individuals with schizophrenia. In this study, minocycline (100 mg twice a day) will be administered for 8 weeks to determine if it is an efficacious antidepressant for individuals with bipolar depression.
NCT01566318
Seniors who receive supportive services face a variety of psychosocial vulnerabilities that put them at risk for depression. One group with very high risk is older adults receiving aging services through Medicaid waiver programs. This 3-year research uses a randomized controlled clinical trial to assess the effectiveness of brief behavioral therapies (problem solving therapy \[PST\] and Brief Behavioral Therapy for Insomnia \[BBTI\]) to prevent depression in seniors receiving aging services.
NCT02916238
Depression is often the most prevalent mental health problem among people living with HIV (PLWH) worldwide, and if not adequately treated, it may impair response to antiretroviral treatment (ART) and the ability of individuals to adhere to medications and healthy behavior. Most patients with depression receiving ART in the poorest countries of the world are left untreated because no systematic approach or expertise is available. This study adapts an evidence-based model of depression care (Measurement-Based Care - MBC) using auxiliary HIV clinic staff, and tests feasibility and assesses costs among HIV positive patients beginning ART in Port-au-Prince, Haiti.
NCT01641146
HIV continues to spread among Black men who have sex with men (MSM), but few interventions target high-risk Black men who have sex with men and women (MSMW). Black MSMW with histories of childhood sexual abuse (CSA) may be an especially vulnerable population for: a) high-risk sexual behaviors; b) negative psychological sequelae (e.g., depressive or posttraumatic stress disorder (PTSD) symptoms); and c) neurobiological abnormalities in cardiovascular, neuroendocrine and/or immune systems (e.g., cortisol and norepinephrine), and HIV/AIDS progression. The purpose of this study was to test an HIV risk reduction intervention, guided by the Social Learning Theory, the Ecological Model, and the concept of allostatic load, a composite of the cumulative effects of stress on biological systems including psychoneuroimmunologic markers. The investigators tested the 6-session Enhanced Sexual Health Intervention for Men (ES-HIM) on 88 non-gay identifying HIV-positive Black MSMW with histories of CSA. The outcomes were to reduce high-risk sexual behaviors (i.e., unprotected anal and vaginal sex and number of sex partners) and negative psychological symptoms of depression and PTSD. Links between these outcomes and biomarkers of stress were also explored. Randomization to either the ES-HIM or a health promotion control group occurred with study participants assessed at baseline, post, 3- and 6-months.
NCT02152878
Non-invasive brain stimulation therapies have been increasingly investigated in recent years as a treatment for neuropsychiatric disorders, particularly mood disorders. They are particularly appealing since many patients are either refractory or present side effects to standard pharmacological regimens. TDCS (transcranial direct current stimulation). a novel non- pharmacological brain stimulation technique, might help in overcoming some of these issues, since it has low cost, high portability and it is relatively easy to use. TDCS consists in applying a weak, direct current through two electrodes placed over the scalp; the anode and the cathode increasing and decreasing cortical excitability during and beyond the period of stimulation. It is also a safe technique with only mild adverse effects described. Previous studies, some of them from our group, have described that tDCS is an effective technique for major depression. However, the role of tDCS as a treatment for bipolar depression (BD) has been insufficiently investigated. Therefore, our aim is to address the antidepressant effects of tDCS in BD in a randomized, sham- controlled trial in a refractory sample.
NCT02000726
Current medical therapies for depression take weeks to achieve full efficacy, and are ineffective in many patients or cause intolerable side effects, emphasizing the need for a deeper understanding of depression and its treatment. Identifying early brain biomarkers of treatments responses seems necessary to improve antidepressant treatment outcome. In this study we aim to detect early brain responses to a fast acting antidepressant-like treatment administered intravenously during a Real-Time Neurofeedback functional magnetic resonance imaging (MRI) Task to predict antidepressant treatment outcome in depression. At completion of the neuroimaging task, participants will enter a placebo-controlled clinical trial with a selective serotonin reuptake inhibitor (SSRI).
NCT02538835
This study evaluates the effect of metacognitive group therapy on depression compared to mindfulness groups and supportive groups. The participants, all with a history of depression and with current symptoms of depression, will be randomized to one of the three group interventions.
NCT01862913
Background: Most adolescents suffering depression are treated in primary care clinics. Cognitive-behavior therapy (CBT) is effective in the treatment of adolescent depression. The availability of appropriately trained CBT therapist may be limited, especially in primary care clinics. One way to increase the availability of CBT is to use computer-assisted CBT (c-CBT). It can be effective in the treatment of adults, although the outcomes in adolescents remain unclear. Purpose: The purpose of this study is to determine whether a computer-assisted cognitive-behavioral therapy is effective for the treatment of depression in adolescents between 15 and 19 years of age in 4 primary care clinics in Santiago, Chile. Study design: A two-arm single-blind (outcomes assessor) randomized controlled trial will be carried out with 216 adolescents. The efficacy, the adherence, and acceptability of the computerized-assisted cognitive behavioral therapy will be evaluated.
NCT00809770
The purpose of this study is to determine the effectiveness of a behavioral treatment, contingency management, in reducing stimulant use in persons with serious mental illness.
NCT02028026
The purpose of this study is to determine whether vilazodone is more effective than citalopram for the treatment of anxious depression. We will use neuroimaging to see whether there are changes in the brains of patients receiving the drug vilazodone that are different from those of citalopram. These changes may show that vilazodone affects the brain differently than most other kinds of standard antidepressant medications.
NCT01515215
Major Depressive Disorder (MDD) is one of the most prevalent mental illnesses in North America, in which 30% - 40% fail to respond to conventional treatment. Repetitive Transcranial Magnetic Stimulation (rTMS) has been shown to be an effective therapeutic tool for the treatment of MDD. This form of treatment involves a series of magnetic pulses directed to the brain for about 30 minutes. Importantly, such treatment is very safe and well tolerated. However, to date, most treatment studies show modest efficacy due to limitations, including: 1) treatments that are delivered to only one side of the brain; 2) treatment that does not directly target a specific brain region associated with depression; 3) treatments that are of short duration; 4) treatments that are of insufficient intensity; and 5) insufficient understanding of the brain mechanisms responsible for therapeutic effect. This study is designed to directly address all of these limitations, as well as explore brain mechanisms (e.g. cortical excitability) through which treatment is optimized.
NCT01573130
The purpose of the study is to investigate the effects of an internet-administered, therapist-assisted physical exercise program for the treatment of depression.
