Filter by:The goal of this clinical trial is to test the efficacy of lactate (a natural substance) in combination with standard antidepressant treatment, in patients hospitalized for a major depressive episode. The main question[s] it aims to answer are: - does lactate diminishes depression severity when administered in combination with antidepressant ? - is it feasible to test lactate treatment in a large-scale clinical trial ? Participants will receive lactate intravenously daily (20 min infusion) for 5 days during hospitalisation (together with the standard antidepressant treatment). Researchers will compare with a group receiving a placebo instead of lactate to see if lactate has antidepressant effects.
The aim of this study is to identify biologically viable targets for the treatment of major depressive disorder (MDD) and anxiety disorder (AD) with the ultimate goal of guiding physicians' therapeutic strategies and identifying more effective and safer treatments for patients. Following the inclusion and exclusion criteria, the investigators will recruit 10 patients with a diagnosis of anxious-depressive disorder (MDD-AD) and 10 healthy controls (HC) subjects. Each participant will be evaluated by a team of expert psychologists and physicians, who will be conducting a structured interview and administering a set of psychopathological scales to assess the symptoms' severity. The participants will also undergo7T multimodal neuroimaging session (including T1-weighted, 1H-MRS and fMRI). In the second part of the study, murine models will be used to study the role of integrin β3 (Itgb3) and protocadherin 9 (Pcdh9) in glutamatergic transmission at a molecular level and to evaluate whether the electrophysiological and behavioral defects identified in Itgb3- and Pcdh9-knockout mice can be restored by CRISPR-mediated transcription activation (CRISPRa).
The present study aims to address gaps in the literature by evaluating the objectively measured dose-response relationship between exercise and depression symptoms; examining changes in resting (Brain-derived Neurotrophic Factor) BDNF from baseline to week 10 of an exercise intervention; and assessing varying exercise intensities on enjoyment, affect, and health-related quality of life in sedentary young adult college students.
This study is a multicenter, randomized, double-blind, and sham-controlled trial using the identical protocol as the SNT to replicate the antidepressant efficacy of SNT for TRD. Patients will be recruited and randomly assigned (1:1 ratio) to receive active or sham groups from 5 hospitals in China. The interventions will last for 5 days and both groups will be followed up for 8 weeks on the same time schedules. During the intervention and at least the first 4 weeks of post-treatment, participants will keep a stable antidepressant regimen. The individualized SNT target in the left dorsolateral prefrontal cortex (DLPFC) will be generated from 30 minutes of resting-state functional MRI collected at baseline.
In this project, the efficacy of different tDCS protocols in major depression will be investigated. The tDCS protocols have already been investigated in humans, and results showed that stimulation intensity has a different effect on tDCS long-term aftereffects based on the human motor cortex model. The project has three major goals: first, we want to see if the differential outcome of tDCS dosage, as present in healthy populations, can be translated to patients with major depression. Second, we want to compare the efficacy of a multi-channel novel protocol with conventional tDCS modules. Lastly, we are interested in the safety and tolerability of optimized multi-channel. The project output will be an optimized tDCS protocol for major depression treatment.
Major Depressive Disorder (MDD) is a very common illness that is usually treated with antidepressant medication. Depression can be caused by many things such as childhood experiences, genetics, and changes in the way the body and brain function. For those with depression where medication and psychotherapy have limited benefit, repetitive transcranial magnetic stimulation (rTMS) is an effective treatment. rTMS is a treatment that involves stimulating certain areas of the brain with magnetic field pulses. Over time, the magnetic field pulses can gradually change the activity level of the stimulated brain region. This can be helpful in treating some kinds of psychiatric and neurological disorder, including MDD. It is not fully known how rTMS changes brain activity to improve symptoms of depression. However, certain brain areas responsible for behaviours impacted by depression are underactive in those with depression. One of those brain regions called the dorsolateral prefrontal cortex (DLPFC), and the investigators will target this region using rTMS. By increasing the activity of these regions, rTMS could potentially improve depression symptoms. For participants receiving rTMS, the investigators will be using the participant's brain scan to better understand brain activity of the brain region stimulated by rTMS before and after treatment. In this study, the investigators will be collecting detailed information about participants' psychiatric history and depression symptoms, as well as brain scans and saliva samples. The saliva samples will undergo proteomic (having to do with proteins) analyses to identify biological markers ("biomarkers": biological features (e.g.: gene, protein) that can be measured to indicate factors related to rTMS response. The investigators' goal is to use this information to help us understand whether improvement to rTMS depends on brain activity or proteomic factors localized to two specific behaviours impacted by depression: reward processing and working memory (the capacity to hold information temporarily, such as holding a person's address in mind while listening to instructions about how to get there).
Major Depressive Disorder (MDD) is a very common illness that is usually treated with antidepressant medication. Depression can be caused by many things such as childhood experiences, genetics, and changes in the way the body and brain function. It is most likely caused by a combination of several of these factors. The prevalence of suicide attempt in Major Depressive Disorder (MDD) is about 20%. Risk for suicide attempt can be increased by many things such as negative life events, genetics, and changes in the way the body and brain function. It is most likely caused by a combination of several of these factors. In this study, the investigators will be collecting detailed information about participants' psychiatric history and depression symptoms, as well as brain scans. The goal is to use this information to help us determine what predicts suicide attempt history.
The goal of this research study is to adapt an ACT-self-help workbook to the prison setting and determine the feasibility acceptability, and effectiveness of this workbook. Participants can expect to be in the study for 13 weeks.
Optimizing treatments in mental health requires an easy to obtain, continuous, and objective measure of internal mood. Unfortunately, current standard-of-care clinical scales are sparsely sampled, subject to recency bias, underutilized, and are not validated for acute mood monitoring. The recent shift to remote care also requires novel methods to measure internal mood. Recent advances in computer vision have allowed the accurate quantification of observable speech patterns and facial representations. The continuous and objective nature of these audio-facial behavioral outputs also enable the study of their neural correlates. Here, the investigators hypothesize that video-derived audio-facial behaviors have discrete neural representations in the limbic network and can provide a critical set of reliable longitudinal estimates of mood at low cost across home and clinic settings.
The FDA approved repetitive transcranial magnetic stimulation (rTMS) for patients with Major Depressive Disorder (MDD) in 2008. The conventional rTMS protocol that has been used effectively for major depression is 5 days per week for 4-6 weeks. The accelerated rTMS protocol involves conducting more than one session per day. In the treatment of post-stroke depression (PSD); although the effectiveness of conventional rTMS procedure has been shown in many studies, there is limited data on accelerated rTMS protocol in which the number of daily sessions is increased. In this study, we aimed to evaluate the efficacy of accelerated rTMS treatment on depression symptoms in patients diagnosed with PSD and whose depressive symptoms persist despite medical treatment, by comparing it with sham stimulation. Question 1: Is accelerated rTMS an effective and reliable method in the treatment of post-stroke depression? Question 2: Is accelerated rTMS effective on quality of life, functional assessment and motor recovery in patients with post-stroke depression?
