Active clinical trials for "Depressive Disorder, Major"

In this study, patients with major depressive disorder (MDD) who have insomnia symptom are treated with Seroquel XR in an open-label manner for a 4-week period with repeated measurements of insomnia symptoms and sleep parameters using polysomnography.

Depression is a common disorder, especially in old age, where it is associated with significant morbidity and mortality. This study will investigate whether there are features of individual patients with major depression that may predict positive treatment response. The study will invite 40 patients who have been diagnosed with major depressive disorder with onset after the age of 60 years to participate. Participants will be recruited from the Mental Health of Older Adults services at the South London and Maudsley NHS Mental Health Foundation Trust. Participants will receive usual treatment as set out in standard Care Pathways, used by the clinical care team. As part of the study, they will undergo a short battery of neuropsychological tests and a standard MRI brain imaging protocol. The neuropsychological tests and assessment of depression severity will be carried out twice (at Baseline and Week 12). Data will be analysed to investigate whether there are features specific to those patients who show a good response to antidepressant treatment after 12 weeks. Identification of such predictors may help to stratify treatment approaches in the future and lead to the early identification of individual patients who may require alternative treatment approaches to standard antidepressants.

This is a preliminary, open-label, clinical trial designed to assess the efficacy, safety, and tolerability of vortioxetine for the treatment of major depressive disorder in patients with coronary artery disease. In addition, the study will assess the effects of vortioxetine on heart rate variability in these patients.

rTMS is a promising, though largely untested, option for treating adolescent and young adult depression. This study hypothesizes that rTMS will safely and significantly alleviate depression and decrease suicidal ideation in adolescents and young adults based on previous studies.

Elevated homocysteine levels are associated with depression and cognitive impairment. When depression ameliorates due to treatment, homocysteine serum levels often normalize. Aim of the present study is to investigate, whether repeated ECT treatment leads to changes in homocysteine levels and if these changes are associated with the occurrence of cognitive impairment after ECS. 10 patients suffering from therapy-resistant depression shall be enrolled. Patients are treated with repeated ECT (three times the week). Before, directly after and one day after ECT treatment, blood samples are drawn and patients receive cognitive testing. Depressive symptomatology is checked with different rating scales.

The purpose of this study is to test a candidate drug, Org 24448,in a phase II clinical trial in adult patients with moderately treatment-resistant unipolar major depressive disorder.

The investigators are testing the efficacy of Smartphone-delivered cognitive behavioral therapy (CBT) treatment for major depressive disorder (MDD). The investigators hypothesize that participants receiving app-CBT will have greater improvement in QIDS-C scores than those in the waitlist condition at treatment endpoint (week 8).

Treatment-resistant depression (TRD) is a common cause of disability and one of the most common psychiatric disorders worldwide. Electroconvulsive therapy (ECT) is currently the most effective treatment for TRD. Recent developments showed esketamine to be a rapid-acting and effective antidepressant drug and it has been hailed as a breakthrough in treating TRD. Common treatment algorithms for TRD list ECT as a treatment option, but esketamine has not yet found its exact position in those algorithms. To the investigators' knowledge, a longitudinal, randomized controlled trial comparing the efficacy of ECT and intranasal esketamine in TRD patients has not been conducted. Furthermore, the investigators intend to measure effects of ECT and intranasal esketamine on brain connectivity and structure, using functional magnetic resonance imaging (fMRI). In this study, inpatients with TRD at the University Hospital for Psychiatry I, Medical University Innsbruck, will be randomized to ECT or intranasal esketamine. Short- and medium-term treatment effects on functional and structural connectivity in the brain will be determined using fMRI.

This study is an open-label, single-arm, within-subjects design in individuals with mild-moderate Major Depressive Disorder (MDD). All participants will receive a single dose of 25mg of psilocybin in a therapeutic setting. In order to investigate the effects of length of time on SSRI therapy, 30 participants with varying lengths of time on SSRI therapy will be enrolled, stratified into four groups: Group 1: ≤ 1 year Group 2: 1 to ≤ 5 years Group 3: 5 to ≤ 10 years Group 4: > 10 years

Participants with depression will be given a single dose of psilocybin and supportive psychotherapy before, during, and after drug administration. Participants will undergo positron emission tomography (PET) imaging before and one week after psilocybin using a marker of synaptic density. This design allows us to assess the relationship between neurotrophic, and antidepressant effects produced by psilocybin.
