Active clinical trials for "Depressive Disorder"

Subjects will be 1000 men meeting the following inclusion criteria: 1) male, age 18-65 years; 2) meeting DSM-IV criteria for major depressive disorder within the past one year, with a HAM-D score >12. Subjects will be excluded if they exhibit 1) a substance abuse or dependence disorder within the past year; 2) current psychotic symptoms; or 3) a history of bipolar disorder. Procedure After informed consent, eligible patients will have blood drawn for serum hormone levels; cortisol, DHEA-S and testosterone or they will provide a salivary sample for measurement of hormone levels. We will also test hormone level form 1000 healthy males (from blood or saliva) at the same age for comparison.

This study will explore and test the feasibility, acceptability, usability, and preliminary effectiveness of a technology-enabled intervention for depression using task-sharing in primary care. We will a) discover barriers and facilitators to task-sharing by frontline primary care staff; b) design an implementation strategy to support task-sharing to deliver a technology-enabled intervention for depression; and c) conduct a small open-label usability trial of the technology-enabled intervention for depression.

This study will be a randomized controlled trial set in an outpatient clinic, involving patients with major depressive disorder, who will be treated with antidepressant therapy, which will be individually agreed upon by the subject and his or her physician. Patients will be randomized to receive either placebo or fish oil capsules containing eicosapentaenoic acid (EHA) and docosahexaenoic acid (DHA) in addition to their antidepressant medication. Subjects will complete a brief dietary and exercise habits survey at the beginning of the trial to take into account lifestyle factors that may be significant in symptom resolution. Their progress will be monitored over a period of twelve weeks, with standardized rating scales completed by subjects and treating physicians. At the end of the study, scores will be compared between groups to look for differences in timing and degree of symptom improvement to analyze whether improvement occurred faster in the group receiving essential fatty acids (EFAs) than in the one receiving placebo. The primary hypothesis is that supplementation of antidepressant therapy with omega-3 fatty acids will decrease the lag period between the start of therapy and the time of clinically significant symptom improvement. A secondary hypothesis is that the results of this study will be consistent with numerous previous studies showing improvement in symptom control in major depressive disorder when antidepressants are supplemented with omega-3 fatty acids.

This study is a 6-month follow-up study to WB001-001 conducted to assess and evaluate the durability of the effect of {WB001+TAU} beyond the 8-week treatment period.

This is an observational study evaluating the safety and efficacy of dronabinol for the treatment of anxiety and/or depression in older adults. Participants who are prescribed dronabinol as part of a voluntary inpatient stay in McLean's Division of Geriatric Psychiatry will be interviewed about their mood and cognition on a weekly basis while on dronabinol.

DELPhI acquisition and analysis software, a QuantalX Neuroscience development, which is designed to measure, analyze, and display brain electrical activity of human electroencephalogram (EEG), to transcranial magnetic stimulation (TMS), will be used to evaluate different psychiatric conditions.

Objectives: To identify peripheral neuroinflammatory markers in patients suffering from major depression or psoriasis in relation to affective symptoms (anxiety, depression, irritability), fatigue and cognitive symptoms; and their change after specific treatments. Methodology: Observational prospective cohort study in patients diagnosed with major depression and patients with plaque psoriasis, who naturalistically undergo different treatments (systemic or biological for psoriasis, antidepressants for depression). Forty-one patients with major depression attending psychiatric consultations and 82 patients with psoriasis attending dermatology consultations at Hospital Universitari Germans Trias i Pujol aged 18 to 65 years old will be selected for inclusion. All of them will be assessed at baseline and after 4 months treatment through a series of demographic and clinical variables, psychiatric diagnosis, psychopathological scales and immunological and biochemical variables after blood draw for obtaining serum, peripheral blood mononuclear cell (PBMC) and extraction of total RNA. Investigators will analyze the correlation between immunological markers and affective and cognitive symptoms at baseline, as well as their variation after treatment. Subsequently, a bivariate comparative analysis will be carried out, where statistically significant or marginally significant variables associated with psychopathological variables will be used to construct a multivariate model of binary logistic regression.

The purpose of this investigator-initiated observational study is to examine how low Ketamine infusion treatments impact antidepressant and anti-suicidal effects for refractory and non-refractory depression.

In this Phase 4 study, women who have been prescribed commercial ZULRESSO™ (brexanolone) by a physician as standard of care for postpartum depression (PPD) and who are planning to receive the infusion per United States Prescribing Information (USPI) at a Risk Evaluation and Mitigation Strategy (REMS)-certified healthcare center are being asked to participate to collect data on multimodal neuroimaging parameters in order to evaluate the relationship between changes in depressive symptoms and changes in neuroimaging parameters.

The investigators will acquire simultaneous EEG and fMRI data from Veterans with depression and schizophrenia and mentally healthy Veterans to assess early sensory responses, context updating, and responses to emotional images. Understanding how rumination affects engagement with the environment is the first step towards assessing its far-reaching cognitive and emotional costs, which cut across traditional diagnostic boundaries. Understanding how mindfulness restores information processing will increase our understanding of how, and for whom, it works.
