NCT ID: NCT05489042 Recruiting - Depression Clinical Trials

Functional Connectivity Alterations in Suicidal Patients Among Opioid Users

Start date: January 4, 2022
Phase: N/A
Study type: Interventional

Suicide is the 10th leading cause of death for Americans of all ages and more people in the United States now die from suicide than die from car accidents. Although death by firearm remains the most common cause of suicide in the United States, an intentional overdose of substance usage such as prescription opioids accounts for over 5,000 suicides per year. In 2017, more than 70,000 drug overdose deaths occurred, making it the leading cause of injury-related death, and well over half (67.8%) involved opioids. The dramatic increase in opioid overdose raises concerns about their contribution to suicidal outcomes (e.g., suicidal behavior, ideation, and attempts). Abuse of prescription opioids is characterized by the persistence of opioid use despite negative consequences. The neurobiology of opioid abuse involves the mesolimbic dopamine systems as the main neural substrate for opioid reward, and altered dopamine release in this system plays a role in opioid abuse. Moreover, the cortico-striatal system, especially the orbitofrontal cortex (OFC), has been associated with the abuse of many substances, including opioids and alcohol. Structural brain alterations in frontal areas, particularly the OFC, may cause executive control dysfunctions of mood which are highly associated with suicidal ideation. Recent preclinical work has shown that higher input from the OFC to the dorsal striatum (dSTR) is associated with compulsive reward-seeking behavior despite negative effects (e.g., punishment). In this study, the investigators propose that OFC/dSTR connectivity may be one neural differentiator that distinguishes between those who become compulsive users after initial opioid use and those that do not. Moreover, suicidal patients among those who become compulsive users may have higher OFC/dSTR connectivity compared to non-suicidal patients.

Anhedonia, Development, and Emotions: Phenotyping and Therapeutics

Start date: July 22, 2022
Phase: Phase 4
Study type: Interventional

The goal of the ADEPT Study is to understand anhedonia in young people and how it changes based on treatments targeting the brain circuit underlying it. Anhedonia is a challenging mental health symptom that involves difficulty with motivation to experience pleasant events. This study could help develop treatments for people whose depression does not improve with traditional treatments. The ADEPT Study includes two phases. In Phase 1, participants are asked to go through a series of activities to measure anhedonia, including MRI scans, blood draws, behavioral tasks, clinical interviews, questionnaires, and app-based assessments of experiences and behaviors. Phase 2 involves therapeutic activities, such as transcranial magnetic stimulation (TMS), positive affect training, and, for some people, ketamine administration. If the participant qualifies and is interested, they may choose to do Phase 2 activities in addition to Phase 1.

NCT ID: NCT05480150 Recruiting - Clinical trials for Major Depressive Disorder

Chinese Longitudinal and Systematic Study of Bioplar Disorder

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

Affective disorders (mainly including major depressive disorder and bipolar disorder) are common, chronic and highly disabling mental disorders, which lack of objective biological markers. It is believed that genetic and environmental factors are involved in the development of affective disorders. Gut microbes can affect the function of brain neural circuits by mediating metabolic, immune, endocrine and autonomic changes along the brain-gut axis. The brain can also regulate intestinal microbes through endocrine, neural structure, neurogenic exosomes and other pathways. Based on the brain-gut axis, this study intends to establish a large cohort of affective disorders, and screen out efficient and convenient biomarkers for clinical diagnosis and efficacy prediction by studying key indicators such as intestinal microbes, serum metabolites and immune indexes, brain-derived exosomes, and brain functional imaging.

Can Virtual Reality Improve the Progressive Muscular Relaxation Technique Efficacy?

Start date: February 8, 2022
Phase: N/A
Study type: Interventional

The purposes of the current research project are as follows: 1. investigate if the PMRT associated with a personalized-relaxing scenario in VR can facilitate the recalling of the relaxing image in the real world than the standard procedure (consisting of PMRT associated with the in-imagination exposure to a comfortable subjective context). The investigators assume that VR would be more efficient than in-imagination since it would make easy the visualization process favor people cope with more realistic sensory experiences than in-imagination exposure. Accordingly, the VR exposure would elicit the strongest association between the relaxation procedure (neutral stimulus, NS) and the relaxing context in VR (conditioning stimulus, CS); 2. whether exposure to a personalized VREs has a more significant impact on anxiety, depression, stress, sense of presence, and quality of psychological well-being; these constructs are investigated by comparing the participants' performance on self-report questionnaires (described in the next section), before the start of the training (T0; baseline), at the end of all the four relaxing sessions, one week after the end of relaxation sessions (T1; day 7), and during follow up (T2; day 14); 3. if the relaxing sessions administered via Zoom are more proper for managing anxiety and stress than a procedure learned via an audio registration. Considering the ability to generate vivid visual images is positively associated with the capacity to feel present in a virtual world, all the participants are asked to fulfill two questionnaires before the VR or the Guided Imagery exposure to investigate the vividness and the capacity to control mental images respectively, and to control the impact of these two dependent variables on the sense of presence self-reported after the in imagination or VR exposure.

Readiness for E-mental Health- Awareness, Acceptance, and Preference Towards Technology-Mediated Mental Health Treatment Among Individuals With Elevated Depressive Symptoms in Hongkong

Start date: March 20, 2022
Phase: N/A
Study type: Interventional

The goals of this study is as follow: 1. to understand the acceptability/perception of seeking E-mental health service versus other options for depression in Hong Kong, 2. to investigate the extent to which people preferring E-mental health service systemically differ from people preferring traditional face-to-face service, and the extent to which digital health interventions increase reach and access to groups who may less well served by traditional mental health services (e.g. people with financial difficulties, men with depression, people with high level of stigma. etc), and 3. to examine whether treatment preferences shift after receiving a clients' decision aids about psychotherapy in digital and in in-person format.

NCT ID: NCT05465928 Recruiting - Clinical trials for Major Depressive Episode

Personalized Repetitive Transcranial Magnetic Stimulation Treatment for Major Depressive Episode

Start date: August 1, 2022
Phase: N/A
Study type: Interventional

Adolescents and young adults with mood disorders experiencing major depressive episode have poor efficacy of medication treatment. Repetitive magnetic transcranial stimulation (rTMS) has been proven adjuvant efficacy in patients with major depressive episode. However, the optimal evidence-based stimulation parameters have not been clearly defined, which greatly limits the efficacy of rTMS in the treatment of major depressive episode. This trial will compare a novel form of personalized rTMS treatment protocol guided by neuroimaging biomarkers to the sham stimulation.The personalized selection of stimulation parameters, such as stimulation site, frequency and magnetic pulse number, will be determined by neuroimaging biomarkers. The study aims to propose a novel personalized neuroimaging-guided rTMS strategy, to evaluate the efficacy and safety of the treatment, further to understand the biological mechanism of the personalized rTMS treatment.
