Filter by:According to the increasing worldwide prevalence rate of psychiatric disorders in youth, the mental health of youth is becoming more and more important. Taiwan's Ministry of Health and Welfare reported the clibing suicide rate of youth in past five years and showed the prevention work and related intervention for youth's mental health was noteable. The definition of emotion regulation was "consists of the extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions, especially their intensive and temporal features, to accomplish one's goals." Emotion regulation strategies including "rumination", "avoidance", "suppression", "Problem-solving", "reappraisal", "acceptance", "social support", and "distraction". Previous studies had examined the relationship between emotion regulation and mental health in youth; maladaptive emotion regulation would increase the individual's depressive and anxiety symptoms. Carstensen proposed social emotion theory in 1995 Selectivity theory (SST) refers to the need for emotion regulation, which activates Social participation in late adulthood. SST assumes that young people are more interested in social interaction behaviors related to information seeking and building self-concept. characteristics of youth affected by many normative challenges such as adolescence, school transitions, and more complex social Landscape; Adaptive emotion regulation will reduce risk of clinical emotion attacks of illness, especially depression and anxiety.To explore the relationship between emotion regulation and mental health from a psychosocial developmental aspect, we focused on the interaction between individual and environment. Compared with the previous generation, most youths of this generation were participating in social activities and building up interpersonal relationships through the internet, suggesting the internet was an important social context.
To evaluate the efficacy, safety, and tolerability of NBI-1070770 compared to placebo on improving symptoms of depression in participants with major depressive disorder (MDD).
This is a Phase 2B clinical study evaluating the effectiveness and safety of SP-624 as compared to placebo in the treatment of adults with Major Depressive Disorder.
This study is a pilot open label crossover trial to assess the feasibility and acceptability of reducing ultra- processed foods (UPF) in a personalized manner from the diets of patients with major depressive disorder who eat a large percentage of UPF.
The aim of this Phase 2a study in patients with MDD is to assess safety and tolerability and preliminary antidepressant efficacy.
This study will evaluate the efficacy and safety of SPN-820 in Adults With Major Depressive Disorder (MDD)
This is a randomized, double-blind, active-controlled, multi-center study to evaluate the efficacy of AXS-05, compared to bupropion, in preventing the relapse of depressive symptoms in subjects with major depressive disorder (MDD) who have responded to treatment with AXS-05.
This project is designed to examine the role of the subgenual anterior cingulate cortex (sgACC) in anhedonia and anxiety in humans with depression, as well as the acute and sustained effects of ketamine on agACC activation and depression symptoms.
This study will apply a comprehensive tools that integrates neuroimaging, psychological evaluation, and sleep monitoring through 18F-MPPF PET/MR, neuropsychological tests, and polysomnography (PSG) to explore the neurobiological mechanisms underlying transcranial alternating current stimulation (tACS) for depressive disorders, mainly focusing on the serotonergic system revealed by Serotonin-1A (5-HT1A) receptor.
Major depressive disorder (MDD) is a chronic mental illness, with 60% lifetime risk of recurrence after the first MDD episode. Despite available treatment options for MDD, only about half to two-thirds of patients respond to first-line antidepressant treatment, and only 30% to 45% of patients achieve remission. Scholars assume that this low remission rate and high rate of treatment resistance are due to the polyetiological nature of the disease, the heterogeneity of the clinical picture of depression, and the lack of biomarkers to stratify MDD subtypes. The aetiology of MDD, although researched extensively, remains unclear. None of the known mechanisms alone explains the pathogenesis of depression, meaning that the interplay of several factors contributes to the development of MDD. Accumulated scientific evidence has supported the importance of the immune system in the etiopathogenesis of MDD. Until now, the cause of the low-grade inflammation observed in this subgroup of MDD patients has been unclear. In the proposed study, the investigators will test a new hypothesis of the immune theory of the development of MDD: the endotoxin hypothesis of neurodegeneration. This hypothesis states that endotoxin, causes or contributes to neurodegeneration. Blood plasma levels of LPS are normally low but are elevated during infections, gut inflammation, gum disease, and neurodegenerative diseases. Dysbiosis may promote increased intestinal permeability ("leaky gut"), which leads to bacterial translocation across the intestinal barrier and into the circulation, thus forming of LPS and LPS-binding protein complex, which triggers the secretion of cytokines. Data suggest that LPS-induced peripheral inflammation can activate neuroinflammation. However, it is not known whether a low-level persistent presence of LPS in the circulatory system can cause low-grade chronic neuroinflammation leading to neurodegeneration and/or symptoms of MDD. Based on existing preclinical and clinical research data, the investigators hypothesise that an increase in blood plasma endotoxin and peripheral cytokines induce BBB dysfunction, neuroinflammation and neurodegenerative processes in specific etiologically relevant structures of the brain and cause clinical manifestation of depressive symptoms and cognitive damage. In this study the investigators are also going to investigate the effects of single nucleotide polymorphisms of four genes in relation to blood plasma endotoxin and peripheral cytokines concentrations and clinical manifestation of MDD.
