NCT ID: NCT03623711 Recruiting - Clinical trials for Major Depressive Disorder

A Prediction Study of Multiple Indexes of the Effect of Different Mechanisms of Antidepressants Treatment on Depression

Start date: August 20, 2018
Phase: Early Phase 1
Study type: Interventional

Antidepressants is the primary treatment for depression, but only less than 50% of the patients get clinical remission. There is no objective markers to select antidepressants for clinical treatment . Clinical choose usually use experience and waste a lot of time, even the patients cannot be treated timely and effectively. The investigators found that the later antidepressant effect for 8 weeks is related with early brain functional response. Present prospectively drug treatment and follow-up study intends to adopt pharmacological imaging research methods to detect the brain function or structure change of three different mechanisms of antidepressant drugs, selective serotonin reuptake inhibitors (SSRIs, escitalopram), serotonin and norepinephrine reuptake inhibitors (SNRIs, duloxetine), norepinephrine and dopamine reuptake inhibitors (NDRIs, bupropion) in depression patients. Brain functional or structural magnetic resonance imaging data were collected at baseline, 1 days, 14 days and 12 weeks after treatment. The investigators want to observe the changes of brain functional networks and structure at different time points, acute and chronic treatment induced during drug treatment. Combined with the blood concentration detection, symptom change, cognitive function tests, the investigators also hope to determine the different mechanisms of drug efficacy of antidepressants with different mechanisms. The second aim is to explore different mechanisms of brain function for effective or ineffective drug response. The results of the study will help to further explain the mechanism of different antidepressants, to facilitate the development of early indicators for drug efficacy and individual treatment decision.

Pulsed Electro Magnetic Fields (PEMF) in Depression

Start date: September 2016
Phase: N/A
Study type: Interventional

PEMF (Pulsed Electro Magnetic Fields) therapy has been used to stimulate bone repair in non-union since the 1970s. This is an accepted use, which has been approved by the Food and Drug Administration in the US. The mode of action of PEMF is based on creating small electrical fields in tissue and thereby promoting healing. Besides it has been shown that PEMF enhance regeneration of nerve fibers exposed to a lesion For treatment of depression the PEMF equipment, which are provided by the company Re5 A/S, consists of a 220 V impulse generator that creates electrical impulses and an applicator which consists of an electrical cable connected to a helmet on which there are 7 electrical coils on the inside. In comparison with the rTMS (Transcranial Magnetic Stimulation) equipment, which uses stimuli approaching neuronal firing level, the PEMF fields in human is very much lower.

NCT ID: NCT03538275 Recruiting - Healthy Clinical Trials

Medibio Depression Monitoring Study

Start date: March 13, 2018
Study type: Observational

An objective measure of treatment response could be a valuable new tool in the armamentarium of depression management, and this holds true for stimulation-based and pharmacological therapies alike. Hence, the Medibio Depression Monitoring Study will use the Medibio analytics platform to characterize autonomic, circadian, and sleep patterns before and during the initial 8 weeks of pharmacologic therapy for moderate-to-severe depression. The study will also explore any differences in these measures between treatment responders and non-responders, and between depression subtypes, including bipolar and unipolar depression. The study will also characterize longitudinal, ambulatory EEG measures throughout the observation period.

NCT ID: NCT03518749 Recruiting - Depression Unipolar Clinical Trials

Effects of tDCS-enhanced Cognitive Control Training on Depression

Start date: March 19, 2018
Phase: N/A
Study type: Interventional

Deficient cognitive control (CC) is one of the central characteristics of major depression (MD). Hypoactivation of the dorsolateral prefrontal cortex (dlPFC) has been linked with this deficit. Antidepressants and cognitive-behavioral therapies modify CC most-likely as a common mechanism of treatment. Transcranial direct current stimulation (tDCS) is a safe, simple and effective non-invasive method to modulate the cortical excitability. It has been shown, that the activity of the dlPFC can be modulated by transcranial direct current stimulation (tDCS) with polarity-dependent learning-phase specific effects on performance that, when combined with training, can outlast the stimulation. The goal of this randomized, sham-controlled, rater blind clinical trial is to investigate the effect of a tDCS-enhanced CC Training (CCT) on depressive symptom severity and compare the stimulation intensities 1mA, 2mA and sham tDCS. Overall, the study will include 57 participants (n = 19 per group). Each participant will complete 12 training sessions with online sham/ anodal tDCS. As a training task we will use an adaptive version of the paced auditory serial addition task (PASAT). In the PASAT, digits are presented auditive and participants have to add the current digit to the digit they heard before. In the adaptive version the interstimulus-intervals decrease (increase) when four consecutive trials are correct (incorrect). The PASAT is known to elicit frustration. Participants have to exert cognitive control over these emotions to complete the task successfully. Before, during and after the training symptom severity will be assessed. Baseline and post-training performance in the PASAT and in a transfer task (delayed working memory task, DWM) will be measured. To further explore variables that influence the effect of tDCS on depressive symptom severity we will measure brain activity (EEG, NIRS), heart rate, global functioning (GAF), emotion regulation strategies, self-esteem, mood ratings and subjective performance ratings before and after the training and collect genetic factors. Sustainability of the training effects will be measured at a follow-up visit (3 months later).

NCT ID: NCT03466346 Not yet recruiting - Clinical trials for Depression, Unipolar

Depression And Primary-care Partnership for Effectiveness-implementation Research

Start date: June 2018
Phase: N/A
Study type: Interventional

Despite carrying the vast majority of the global mental disorder burden, 75% of adults with mental disorders in Low and Middle Income Countries have no access to services. This study will test strategies for integrating evidence-based depression treatments with primary care services at a large public sector hospital and conduct robust cost and cost-benefit analyses of each treatment to produce a "menu" of cost-benefit options for integrated depression care with corresponding effectiveness and implementation values. The project is relevant to the mission of the National Institutes of Mental Health because it addresses mental health care delivery and related health economics at the individual, clinical and systems levels.

NCT ID: NCT03405493 Recruiting - Depression Clinical Trials

Sleep, Wake and Light Therapy for Depression

Start date: January 18, 2018
Phase: N/A
Study type: Interventional

The aim of this study is to determine if altering the pattern of one's sleep and having light therapy can speed up the treatment of depression. In the UK, the large majority of patients with depression in the NHS are treated in the community, and one of the major objectives of the study one is to determine if this therapy is a practical treatment in the community. We will be comparing two treatments: 1. Sleep Therapy and a Light Box: Participants will be given information and advice on how to get a good night's sleep. Participants will be given a light box to use in the morning for 1 week. Treatment with a light box will last 30 minutes when a person gets up. Participants may continue to have any treatment as usual (for example medication or talking therapies). 2. Wake therapy and a Light Box: Participants will be helped to change the pattern of sleep by depriving participants of sleep for one night. Participants will go bed at 5pm on the following day for 8 hours and get up at 1am. Participants' sleep will then be advanced by 2 hours each night for the next three nights. Participants will be also given a light box to use in the morning for 1 week. Treatment with a light box will last 30 minutes when participants get up. Participants may continue to have any treatment as usual (for example medication or talking therapies).

NCT ID: NCT03246789 Recruiting - Clinical trials for Mental Health Disorder

Reaching and Engaging Depressed Senior Center Clients (REDS)

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to test the feasibility of two types of group therapy sessions. The research is being done because the researchers are trying to learn if these approaches could be used by therapist in the community social service agencies to treat older adults with depression. There are two study groups. One group is a form of group therapy called "Engage-M", which encourages subjects to engage in physical and social activities that they find pleasurable or rewarding. One group is another form of group therapy called, "Wellness in Mind and Body", which focuses on education and de-stigmatization of health and mental health conditions.
