Filter by:Given the importance of cognitive function on depressed patients' treatment outcome and return to premorbid functioning, the effect of antidepressant drugs on cognition has become of primary concern. The aim of the present study is to assess the clinical outcome of switching from a selective serotonin reuptake inhibitor (SSRI) to desvenlafaxine on cognitive function in a Spanish sample of adults with moderate to severe major depressive disorder (MDD). This open-label clinical study will include a total of 36 MDD outpatients receiving treatment with desvenlafaxine according to treating psychiatrist clinical judgment. The primary efficacy endpoint will be changes from baseline to week 12 in cognitive function measured by a composite z-score comprising the Digit Symbol Substitution Test (DSST) and Rey Auditory Verbal Learning Test (RAVLT) scores. The secondary efficacy endpoints will involve depression severity, additional measures of subjective and objective cognitive function (including cold and hot cognitive function tasks), and functional status. A matched sample of 36 healthy controls will be assessed in order to obtain reference data for all cognitive function measurements. Patients with MDD and healthy controls will be compared regarding cognitive function both at baseline and after 12 weeks.
Randomized clinical trial that aims to increase physical activity levels in people with depression and to evaluate if the increase on PA levels has impact on clinical and biological measures.
The investigators examine whether adding yoga-based therapy (YBT) to treatment as usual (TAU) for young adult women (age 18-34 years) with a primary diagnosis of MDD leads to (1) greater reductions in symptoms and (2) greater cost-effectiveness in that the economic benefits of adding YBT to TAU outweigh the costs.
This trial attempts to evaluate the treatment efficacy of Simplified Cognitive Behavioral Therapy (SCBT) and its safety among schizophrenia patients. Half of participants will be randomized to accept SCBT.
Since capability for suicide involves overriding potential pain, and the opioid system plays a strong role in controlling pain perception, it follows that capability for suicide may be impacted by the opioid system. The goal of the proposed research is to identify the neural network underlying capability for suicide in order to determine if it can be a target for identifying high-risk individuals and for intervention.
In this proposed study, the investigators will evaluate the effects of fish oil add-on in treatment of major depressive disorder(MDD).
Background: Repetitive transcranial magnetic stimulation (rTMS) is a treatment for depression. It stimulates the brain. Researchers want to see if using magnetic resonance imaging (MRI) scans helps locate the best area for rTMS in each person. They also want to find other ways to make it more effective. Objective: To study the effects of combining MRI- guided transcranial magnetic stimulation (TMS) and talk therapy on the brain in people with depression. Eligibility: Adults ages 18-75 with a major depressive disorder and current depression. If taking an antidepressant, should have been doing so for at least 4 weeks. Design: Participants will be screened with medical and psychiatric history, psychiatric evaluation, physical exam, and blood and urine tests. Phase 1 is 1-4 visits in 1 week. Participants will have: - Brain MRI. Participants will lie on a table in a scanner. - Questions about their medical history and psychology symptoms - Tests of mood and thinking - Tests of brain activity. Participants may do tasks during these tests: - A cone with magnetic detectors is put on the head. - A cap with electrodes is put on the scalp. - TMS. A brief electrical current passes through a wire coil on the scalp. - A metal disk will be placed on the arm. A nerve will be stimulated with a small electrical shock. Phase 2 is about 6 to 7 weeks. - There will be 30 daily sessions of combined therapy and repetitive TMS (rTMS) for 6 weeks. - Participants will receive rTMS and another therapy by computer. - For rTMS, repeated pulses will pass through the coil. - This is followed by up to 3 additional visits, when: - Participants will repeat Phase 1 tests - Participants will rate their depression symptoms. Phase 3 is 3 visits over 3 months. Participants will rate their depression symptoms and repeat some of the previous questionnaires and tests of mood and thinking.
The purpose of this study is to look at the safety of a study treatment with stem cells in Alcohol Use Disorder And Major Depression (AUD-MD) subjects.
Background Major depression is associated with morbidity and increased mortality. Along with the psychological strain depression represents a high socioeconomic burden costing Europe more than €113 billion/year. About one third of patients do not respond to appropriate therapy. Theta-burst stimulation (TBS), a form of transcranial magnetic stimulation is an emerging treatment for patients for whom pharmacological treatment is ineffective or not appropriate. Based on two different theories of prefrontal dysfunction two TBS-protocols should have the most antidepressant effects. However, no study so far has compared the two approaches or systematically investigated their differential effects on brain function and on a symptom level. Objectives of the study The aim of this study is to test two TBS protocols on symptom improvement and associated brain function in patients with treatment resistant depression (TRD): iTBS over bilateral DLPFC and iTBS over left and cTBS over right DLPFC. As stimulation over non-motor regions offers no direct readout, fMRI at baseline and after treatment will be harnessed to quantify an effect on brain activity and functional network metrics. Study population 80 patients with TRD will be enrolled with 40 patients receiving the one, and 40 patients receiving the other TBS protocol for a treatment period of three weeks. Study design The study is designed as a longitudinal, randomized and double-blind clinical trial. At baseline and after treatment, patients will undergo psychiatric testing using several symptom scales including the Hamilton Depression Rating Scale (HAMD-17), the Beck Depression Inventory (BDI-II), the Inventory of Depressive Symptomatology (IDS-C) and the State-Trait Anxiety Inventory (STAI). Changes in HAMD-17 scores are defined as primary endpoint. Moreover MRI scans before and after treatment will include structural and functional MRI sequences as well as diffusion weighted imaging (DWI) sequence. Functional connectivity and BOLD responses will serve as primary imaging endpoints. A follow-up visit 2 weeks and a final examination 4 weeks after treatment will elucidate durability of effects. Relevance and implications of the study By investigating which approach is superior for which symptoms our study will contribute to the development of personalized treatment, the reduction of personal suffering and the reduction of costs and occupational disability.
Recent studies have suggested that gut-brain axis may be one of the mechanisms of major depression disorder (MDD). In animal studies, alteration of gut microbiota can affect animal's depression or anxiety-like behavior, brain neurochemistry and inflammation. In human studies, the composition of gut microbiota is different between patients with MDD and healthy controls. In addition, supplementation of probiotics can improve mood status in community and clinical participants. Inflammation is one of possible pathway to connect gut and brain. Gut permeability and inflammation level are higher in patients with MDD. Lactobacillus plantarum PS128 in one of bacteria extracted from traditional fermented food, Fu-Tsai. It can alleviate depressive-like behavior reduce inflammation level in maternal separation mice. This study is an 8-week open trial to investigate the effects of Lactobacillus plantarum PS128 on psychophysiology in patients with MDD and higher level of inflammation. This is a two-phase study. In the first phase, we will recruited patients fulfilling the following inclusion criteria: Age 20-65; fulfill Diagnostic and Statistical Manual of Mental Disorders fifth version (DSM-V) criteria of major depressive episode in recent 2 years; Psychotropics including antidepressants, antipsychotics and hypnotics have been kept unchanged for at least 3 months. The exclusion criteria are: comorbid with schizophrenia, bipolar disorder, or other substance use (except tobacco) disorder; having active suicidal or homicidal ideation; known allergy to probiotics; comorbid with hypertension, diabetes mellitus, irritable bowel syndrome, inflammatory bowl disease, liver cirrhosis, or autoimmune diseases; known active bacterial, fungal, or viral infections in one month; use of antibiotics, steroid, immunosuppressants, probiotics, or synbiotics in the month before collecting blood and fecal samples; pregnant or lactating women; who state to have dietary pattern changed or in diet within previous two months. Those hs-CRP > 3 mg/L in the first screen will be invited into the second phase intervention. In the second phase intervention, we will give eligible patients Lactobacillus plantarum PS128 for 8 weeks, and compare depression symptoms, gut microbiota, gut inflammation and permeability, and serum inflammation level before and after intervention.
