Filter by:Most clinical major depression responds to standard treatments (medication and psychotherapy); however, a significant subset of depressed patients (15-20%) do not respond to these treatments and are referred to as treatment-resistant major depression (TRMD). New treatments for TRMD are needed, and one promising line of research are drugs known as N-methyl-D-aspartate (NMDA) glutamate receptor antagonists. In a recent pilot study, the investigators of this study demonstrated that the NMDA antagonist nitrous oxide is effective in TRMD, reducing depressive symptoms, guilt, and suicidal thinking. To more closely investigate suicidal thinking, this study is designed as a double-blind, randomized, prospective, inpatient trial comparing inhaled nitrous oxide (N2O) plus treatment as usual versus inhaled placebo plus treatment as usual. All unipolar depressed, acutely suicidal inpatients will receive standard treatment for their depression/ suicidal thinking (TAU). Additionally, participants will undergo a maximum of four one hour inhalation sessions as inpatients and 2 booster sessions as outpatients during which they will receive either inhaled nitrous oxide (50% nitrous oxide/50% oxygen = active treatment) or placebo gas (50% nitrogen/50% oxygen). A target total of 50 patients with suicidal ideation and unipolar depression will be enrolled, 25 of whom will be assigned to the TAU control group and 25 of whom will be assigned to the N2O + TAU experimental group.
This study evaluates the effectiveness of re-treatment using accelerated schedule of intermittent theta-burst stimulation for treatment-resistant depression. This is an open label study.
This study aims to determine if a short audio clip about mindfulness implemented during NST appointments can lower pregnant women's levels of anxiety and depression. Subjects will be placed into either the intervention group or a control group. The intervention group will be asked to listen to a short audio clip on mindfulness during their NST appointments, and the control group will receive the standard of care during NST appointments. Subjects will be asked to take two surveys about anxiety and depression three times throughout the study: before the intervention, after the intervention, and 6 weeks postpartum.
Consenting subjects with Bipolar depression will remain under the care of their local (psychiatric) care provider and be randomized to a six week course of one of two forms of oxcarbazepine (extended release or immediate release. Study outcomes will be assessed based on outcome measures administered to the subject at home by a computer simulated rater. Local care providers will receive "pre-assessment" reports ahead of each clinical visit, rate the Clinical Global Impression for Severity, and evaluate adverse effects. The primary outcome variable is "treatment effectiveness" operationally defined as the response rate X the completion rate.
Access to effective treatment resources is a ubiquitous problem in behavioral health. There is a need for effective interventions that are more easily accessed at a lower cost. This study will compare outcomes for two models of treatment: 1) The experimental group, Therapy Assistance Online (TAO), and 2) the comparison group, treatment as usual.
The purpose of this study is to determine if taking a probiotic supplement versus a placebo will reduce relapse and improve the clinical course among participants who have been hospitalized for bipolar depression.
Prader-Willi Syndrome (PWS) is a multisystemic genetic disease characterized by hypotonia, mental retardation, hyperphagia, and uncontrollable hunger due to hypothalamic dysfunction, caused by dysregulation of genes located in chromosome 15q11-q13. The goal of this study is to evaluate the effects of Transcranial Direct Current Stimulation (tDCS) on hyperphagia and behavior in PWS. Forty children and adolescents (11-24 years) with clinical and cytogenetic-molecular diagnosis of Prader-Willi syndrome will be assessed before and after 10 tDCS session with: Food Craving Questionnaire (FCQ), Aberrant Behavior Checklist (ABC), Dykens hyperphagia questionnaire. Caregivers self-reported the participant's behaviors at home and, lately, they will be categorized and quantified. tDCS will be applied for 20 minutes with electrodes of 25cm2 wrapped in cotton material soaked in saline solution. The anode at the left dorsolateral prefrontal cortex (F3) and the cathode at the contralateral area (F4). Children from 11-12 years will receive a current of 1mA; above 13 years, 2mA.
In the past, there were studies on relationship between insomnia and depression, and those studies found that depression can be the result of untreated insomnia. Mostly insomnia precedes depression, and is a marker for recurrence of depression. Research suggests that insomnia may cause depression by changing the emotional response. In this study, investigators will establish the national online cognitive behavioral therapy for insomnia (e-aid Cognitive Behavioral Therapy for Insomnia, eCBTI ) tools, and online health education on sleep (e-aid Sleep Hygiene Education, eSHE ) tools for controls. Investigators will be testing whether eCBTI can reduce the incidence of depression in patients with sleep disorders, increasing remission rate of depression, and a corresponding reduction in suicidal ideas, compared with eSHE control groups.
The investigators hypothesized that depression is associated with home sleep EEG, subjective sleepiness and insomnia symptoms. To test this, the investigators plan to perform sleep examination with single channel EEG, in combination with questionnaire survey for insomnia, sleepiness, depression and job stress to Koka city government employees.
The main goal of the research is to apply and evaluate the web-based preventive intervention (the Be a Mom program), in terms of its efficacy, acceptability and feasibility (user's adherence, dropout), and user's satisfaction. Prior to the randomized controlled trial (RCT), the investigators will conduct a pilot trial to evaluate the preliminary version of the Be a Mom program in high-risk women (random assignment to the intervention or to the control condition). The RCT will be a two-arm prevention trial. Women who have had a child during the prior month will be enrolled in the study. A minimum number of 1000 women will be enrolled in the study. After agreeing to participate in the study, the women will be screened for the presence of risk factors for PPD and early-onset PPD symptoms (using self-report questionnaires) by a researcher (licensed psychologist). In case of a negative screen, women's participation in the study will end. In case of a positive screen (high-risk women), women will be randomly assigned to one of the conditions: the intervention (Be a Mom program) or the control condition. The sample will be recruited online and at the maternities of Coimbra University Hospitals-CHUC, EPE. Participation in the study will last 11 months. The Be a Mom program will last 5 weeks. Participants in both conditions will be invited by the researchers via email to complete baseline, post-intervention and follow-up (4-months and 12-months after childbirth) assessments. Assessments will include self-report questionnaires to assess several indicators (e.g., depressive and anxiety symptoms, dyadic adjustment, mother-child bonding, and maternal confidence), mechanisms that may be involved in the treatment response (e.g., npsychological flexibility, emotional regulation) and user's acceptability and satisfaction.
