The goal of this clinical trial is to investigate if the drug D-Cycloserine (DCS) improves the antidepressant effects of Intermittent Theta Burst Stimulation (iTBS), a non-invasive brain stimulation therapy, in patients with Major Depressive Disorder (MDD). The main questions it aims to answer are: - Whether taking DCS prior to iTBS therapy will be more effective in improving depressive symptoms than iTBS therapy alone. - Compare the effect of DCS 100mg/day versus 50mg/day on depressive symptoms. - Test the safety and tolerability of DCS. Participants will take either 50mg DCS per day, 100mg DCS or placebo prior to each iTBS treatment session. iTBS treatment will be administered daily, 5 days a week for 4 weeks. Clinical measures will be conducted at baseline and at the ends of weeks 1, 2, 3 and 4 of treatment.
This experiment intends to explore the differences among various types of depression, as well as the differences between healthy subjects and depressed patients, and find possible biological markers from the severity of symptoms, social function and cognitive function of depressed patients, combined with EEG characteristics, biological test indicators (blood, faeces, hair, etc.) and functional magnetic resonance imaging data. To explore the changes in clinical symptoms, cognitive and social functions, and biological indicators of various types of patients before and after treatment, to provide references for the prognosis of various types, and to predict the future development of the disease according to the baseline indicators of patients; According to the above aspects, this experiment can follow up the patients with depression, track their disease development, and study the potential biological changes in the early stage of the disease, which has the potential to reveal the pathogenesis and provide guidance for the early diagnosis and intervention of depression.
The purpose of this study is to establish how personalization of repetitive transcranial magnetic stimulation (rTMS) can change markers of brain activity and improve treatment response. To do this, all participants will receive the same active form of treatments, but some of the participants in this study will receive intermittent theta burst stimulation (iTBS) rTMS treatment with standard forms of targeting and intensity, and others will receive iTBS rTMS treatment using personalized magnetic resonance imaging (MRI) and electric field (E-field) modeling measures.
Measurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. This study intends to compare differences of efficacy between the implementation with eMBC using WeChat and the standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.
The purpose of the project is to study the effectiveness of Interpersonal Psychotherapy (IPT) for adolescents with depression. Specific aims are to analyze the effects, change mechanisms, predictors, and implementation of IPT for youth. In this four-year project we will include 60 patients with depression. Outcome will be studied using a quasi-experimental multiple-baseline design. Change mechanisms will be studied in the form of mentalizing, emotion regulation, social support, and working alliance session-by-session, and with post-treatment qualitative interviews about the participants' experiences of change. Predictors of effectiveness of IPT for adolescents will be explored by measuring severity of symptoms, anxiety symptoms, presence and severity of parent-child conflicts, quality of interpersonal relationships, experiences of bullying, and school functioning. The implementation process of IPT for youth will be studied through interviews with adolescents, parents, therapists, co-workers, and local managers. The study is conducted within child and adolescent psychiatric services in Norrköping using a practice-oriented research strategy which emphasizes close collaboration with clinicians. The project is a collaboration between researchers at Linnaeus University and Linköping University, and clinicians at BUP Norrköping.
Depression is the most common mental disease and the second leading cause of chronic disease burden, which is closely related to suicidal behavior. The diagnosis and treatment of depression still lack of effective biological indicators, and about 30% of patients with depression still can not relieve their depressive symptoms after treatment. Previous studies have found that ATP release from astrocytes plays an important role in the occurrence, development and treatment of depression. Epoxy eicosotrienes (eets) are closely related to the function of the nervous system and may be the pathophysiological mechanism of depression. Soluble epoxide hydrolase (SEH) can regulate ATP release by affecting EET degradation, leading to depression like behavior and antidepressant effect, and sEH is closely related to cognitive function of depression.
The purpose of this research study is to determine if application of near infrared energy to the forehead can change blood flow in the brains of people with depression. Near infrared energy is like light but is not visible to the human eye.
This study will examine if brain insulin resistance is a feature of depression in humans using magnetic resonance imaging (MRI) measures sensitive to brain insulin action. This study will examine adolescents, as depression onset commonly occurs during this age, and the impacts of cumulative medication exposure and other lifestyle-related confounds are also lower in this age group, improving our ability to understand the underlying biology.
This study will determine the effects of pregnenolone on brain function, inflammation and depressive symptoms in people with HIV who have depression. Participants in this study will receive a pill of either pregnenolone or placebo, and can stay on their current antidepression medications. Brain imaging and behavioral assessments will be performed during the study.
