Active clinical trials for "Depressive Disorder, Major"

Retrospective study in a single academic regional transgender referral center. data from the cohort follow-up in CHRU de Nancy

To study the impact of genetic and environmental factors on high-level cognition associated neural circuits among healthy young Chinese Han subjects.

Aim 1 is to study prevalence and 1 year incidence of metabolic syndrome in major depressive disorder and factors correlation. Aim 2 is to study prevalence and 1 year incidence of thyroid dysfunction in major depressive disorder and factors correlation.

Background: The gut microbiome is emerging as an important factor in regulating mental health yet it remains unclear what the target should be for psychiatric treatment. Investigators aim at elucidating the complement of the gut microbiome community for individuals with Major Depressive disorder (MDD) and Bipolar disorder (BD) relative to controls, and test for relationships with symptoms. Methods: Investigators prospect to recruit subjects including patients and controls amount to 240. All subjects will be collected for blood and stool samples,assessed by clinical scales. Finally, analyzing the correlation among the metabolon in blood, microbiota in stool and clinical scales to obtain the possible interaction between diseases and gut microbiota.

This study aims to 1) examine common and specific emotional and cognitive dysfunctions between Major Depression and generalized anxiety disorder; 2) Examine emotional and cognitive dysfunctions between the two disorders and healthy controls; 3) Examine the biomarkers predicting successful therapy or not.

The Mood Disorder Cohort Research Consortium (MDCRC) study is designed as a naturalistic observational prospective cohort study for early-onset mood disorders (major depressive disorders, bipolar disorders type 1 and 2) in South Korea.

Determination of incidence and prevalence of PTSD and other types of psychopathology (such as anxiety and affective disorders) after traumatic birth experiences and elucidation of salient risk factors in the local population sample- by prospective follow-up.

This study aims to examine the relationship between mood and brain activity in adolescent girls in order to better understand the genetic and neural predictors of adolescent depression. The participants in this study will be healthy female adolescents aged 12-14 and their mothers. They will participate for a total of six months. Adolescent participants will have three study sessions at McLean Hospital, and during two of them, their mothers will also have assessments. Adolescent assessments will include interviews, questionnaires, computer tasks, and collection of a saliva sample for genetic analyses. Their second study visit will include an fMRI scan. Parent assessments will include an interview, questionnaires, and a computer task.

Early improvemrnt, decreased 20% in the 17 items of Hamilton Depression Rating Scale (HAMD-17) at the second week of the treatment of major depression disorder (MDD), can arguably predict the remission at the 12th week. Our observation study including 80 MDD patients will access resting-state function MRI to finding factors which infuencing early improvemrnt, respone and remission of antidepressants.

Target of the research Based on change of Brain-derived neurotrophic factor and other pro-inflammatory cytokine along with symptom improvement following treatment, the investigators are trying to find the new treatment target molecule. The investigators will follow up the subjective and objective cognitive dysfunction with psychiatric symptom profiles and compare the neuroimaging related to these change.
