Filter by:The goal of this clinical trial is to test the efficacy of whole-body hyperthermia in major depression. The main question it aims to answer is: • Does whole-body hyperthermia alleviate symptoms of depression? Participants will be randomised to sham or active whole-body hyperthermia. The study will last 6 weeks during which five visits will take place. Depression will be measured repeatedly and biological mechanisms will be investigated.
Depressive rumination, a negative thinking style characterized by repetitive and passive thoughts about the causes, meanings, and consequences of one's feelings and distress, is often described as being a habitual response tendency that forms a vulnerability to depression. Behavioural Activation (BA) is an effective treatment for depression but little is known of mechanisms of changes during a successful treatment completion and for whom the treatment benefits the most. The main purpose of the study is to investigate whether habit-like mood-reactive rumination will change during Behavioral Activation treatment for current depression and mediates symptom changes in the treatment. Important moderators of change will also be investigated (i.e. history of early life stress and cognitive flexibility). We aim to provide individual BA treatment for up to 130 currently depressed participants in 12 treatment sessions over 11 weeks. Measures are obtained at pre-treatment, during treatment, at post-treatment and at 6 month follow up.
This study will test whether it is feasible to conduct a clinical trial of mirtazapine (an antidepressant tablet) in patients who have both depression and inflammatory bowel disease (IBD). The study design is a randomised controlled trial (a study in which people are allocated by chance to receive different interventions). The trial will compare mirtazapine against a placebo (dummy) tablet in 76 patients with both depression and IBD. The investigators will recruit outpatients aged 18 or over with a diagnosis of any IBD attending gastroenterology clinics. Either in person or remotely, patients will complete a brief screening questionnaire for depression. Those scoring positive for depression will be invited for a 15-minute interview for clinical depression. Those with clinical depression will be invited to take part. Participants will be randomly allocated by a computer to take either 1) mirtazapine tablet once at night for 12 weeks; or 2) placebo (dummy) tablet once at night for 12 weeks. The study is 'blinded', meaning neither patients nor the study team will know which medication they are taking. Throughout, participants will be able to access other treatments for depression, such as talking therapies. The investigators will measure how many people join the study; how many remain in the trial; how many complete treatment; how many tablets people take; and assess overall acceptability of the trial. Participants will complete brief questionnaires to measure their mental health and IBD symptoms after 4 weeks, 8 weeks, 12 weeks and 16 weeks. Participants will also provide blood samples and faecal samples to measure inflammation. If successful, this trial will support an application for a larger version of the study.
The aim of this Phase 2a study in patients with MDD is to assess safety and tolerability and preliminary antidepressant efficacy.
Major depressive disorder (MDD) is a chronic, recurring and potentially life-threatening illness that affects up to 10% of the population across the globe.Increasing evidence indicates a clear link between immune dysfunction and MDD.Moreover, an activation of inflammatory pathways is associated to a lack of clinical response to antidepressants. Thus, the regulation of inflammation represents a potential approach to modulate the link between the living environment and antidepressant outcome. Light therapy combined with sleep deprivation hastens recovery, with benefits that can be perceived by patients during the first week of treatment. Alteration of the sleep-wake cycle and of sleep structure are core symptoms of MDD.The aims of the present project are (i) to show that neural plasticity and the environmental context are moderating factors of the therapeutic outcome of immune modulation and (ii) to exploit their interplay to set up novel and effective therapeutic strategies for MDD.This is a observational prospective study with non-invasive add-on procedures (Magnetic Resonance without contrast). In this study, 60 patients with a depressive episode in course of MDD and treated with a chronobiological intervention including total sleep deprivation (TSD) + light therapy (LT), as performed in clinical practice, will be studied. All participants enrolled in the study will receive Treatment As Usual (TAU), i.e., pharmacotherapy, chronobiological intervention plus clinical management. Drug prescription will be performed during the clinical management sessions.The study will have a total duration of 24 months. Each subject will participate in the study for 6 months, will undergo Magnetic Resonance Imaging (MRI) and clinical evaluation at baseline, after one week of chronobiological treatment and at 6 months follow-up.
Major depressive disorder (MDD) is a chronic, recurring and potentially life-threatening illness that affects up to 10% of the population across the globe.It posits that the increase in serotonin levels induced by Selective Serotonin Reuptake Inhibitors (SSRIs) does not affect mood per se, but enhances brain plasticity and thus amplifies the influence of the environment on the individual. Thus, SSRI treatment has not a univocal effect but, in a favorable environment, it would lead to a reduction of symptoms while in a stressful environment might lead to a worse prognosis.Such innovative view opens new perspectives on how to improve SSRI efficacy by controlling the environment. However, often it is not possible to act on the quality of the living environment because of constraints due to patient's personal history and unchangeable life circumstances. In these cases, the pharmacological modulation of the factors underlying the link between living environment and SSRI efficacy represents a novel and desirable strategy to improve treatment outcome even in patients living in adverse conditions, which are very common in depressed patients. Inflammatory levels are markedly affected by the socioeconomic status and thus by the quality of the living environment. The hypothesis of the present project is that inflammation mediates the influence of the environment on SSRI outcome.Therefore, the control of inflammatory levels is a promising strategy to improve treatment efficacy and overcome the limited SSRI efficacy, especially when administered in patients living in adverse conditions. A further hypothesis is that the influence of the environment on inflammation, in turn affecting SSRI efficacy, occurs through epigenetic modifications. Therefore, the project aims at developing a pharmaco-epigenetic approach as effective treatment for MDD. In addition, through neuroimaging investigations, it will provide important information about functional and structural brain modifications associated to SSRI efficacy in patients. Both males and females will be considered because MDD is twice as common in women than men, suggesting that different mechanisms may underlie the psychopathology in the two sexes.
The prefrontal cortex, although well established as an efficacious target for the treatment of major depressive disorder (MDD), has recently come into favour as a therapeutic target for alcohol use disorders (AUD). Depressive symptoms are also highly prevalent in individuals with AUD. A number of cognitive and psychological processes stemming from the prefrontal cortex, a common treatment target for repetitive transcranial magnetic stimulation (rTMS), are disrupted in both MDD and AUD. The proposed study will enhance the development of theta burst stimulation (TBS) as a new intervention for AUD in the context of depressive symptoms and uses integrated TMS-EEG to identify neurophysiological targets of executive dysfunction in this disorder.
PROSPECTIVE INTERVENTION STUDY; EFFICACY OF WEB-BASED ACCEPTANCE AND COMMITMENT THERAPY
The goal of this clinical trial is to test a new brain stimulation treatment target for individuals with depression plus at least one additional psychiatric disorder. The main question is to understand the safety profile of a non-invasive form of brain stimulation called accelerated intermittent theta burst stimulation when it is targeting the posterior parietal cortex. Additional questions focus on whether this stimulation improves symptoms of depression and other psychiatric disorders as well as whether this stimulation changes brain function.
The purpose of this study is to use transcranial magnetic stimulation (TMS) to better understand the neural circuits associated with social motivation. Participant includes four study visits each that range from 1.5 - 3.0 hours in duration over approximately a one month period. The first study visit involves answering survey questions, a clinical interview, and computer tasks. The second study visit involves a magnetic resonance imaging (MRI) scan, computer tasks, and a brief TMS protocol. The second and third study visits involve a full session of TMS followed by an MRI scan and computer tasks. Adults in the Auburn/Apelika area who avoid social situations, experience symptoms of depression or social anxiety, and are between 25 years old and 50 years old are eligible to participate.
