Filter by:The goal of this randomized placebo controlled trial is to compare the antidepressant effect of a single oral dose of psilocybin 25 mg compared to 1 mg in 100 patients with cancer related major depressive disorder. The main question it aims to answer is: The primary objective of this study is to evaluate the efficacy of a single 25 mg oral dose of psilocybin for major depressive disorder (MDD) compared to an active placebo (psilocybin 1 mg) assessed as the difference between groups in changes in depressive symptoms, in the following Population: 20-80 (inclusive) years old, current depressive episode (according to Patient Health Questionnaire (PHQ-9) ≥10), >1 month after cancer diagnosis, with at least 12 months of life expectancy, willingness to abstain from other psychotherapeutic or antidepressant treatments during the study (wash out time 5 half-lives).
The purpose of this study is to learn whether Functional Electrical Stimulation (FES) of the facial muscles is effective in treating major depressive disorder (MDD) and to develop a model for take-home delivery.
To explore the effectiveness and safety of rTMS intervention with different targets in the left prefrontal cortex defined using the pBFS method, in adult patients with moderate and severe depressive disorder. Second, investigate the neural circuit that responds to the rTMS intervention using individualized brain image analysis, which may help to establish an effective target for the neuromodulation of patients with major depressive disorder.
The purpose of this study is to determine the safety and feasibility of sequencing psilocybin therapy with a short-duration, aiTBS protocol (Stanford Accelerated Intelligent Neuromodulation Therapy, or SAINT) in individuals with treatment-resistant major depressive disorder.
Premenstrual dysphoric disorder (PMDD) is a sex-specific depressive disorder where depressive symptom severity drastically changes in relation to menstrual cycle phase. It is characterized by late luteal phase symptoms of affective lability, irritability, depressed mood, and anxiety. A lot remains unclear and further studies are needed in order to improve the understanding of PMDD and to differentiate it from major depressive disorder (MDD). To date, and in contrast to MDD, the neural correlates of PMDD have been sparsely and poorly investigated. The aim of this study is therefore to investigate the neural correlates of PMDD as compared to MDD and to relate them to stress reactivity. Therefore, three groups of naturally cycling women will be investigated and compared, namely (1) women with MDD, (2) women with PMDD, and (3) healthy control women. Stress and HPA axis activity are assumed to play a crucial role in the development of many mental disorders, including MDD. How stress reactivity and HPA axis activity are connected to PMDD still needs to be investigated. Furthermore, the HPA axis can affect or suppress the activity of the hypothalamic-pituitary-gonadal (HPG) axis, which is involved mainly in the reproductive, but also the immune system, making it an important candidate for the investigation of sex-specific differences in stress reactivity. There are sex-specific differences in stress reactivity, but also in the prevalence of stress-related diseases. Women are twice as likely to suffer from depression than men and the first onset of MDD usually peaks during the reproductive years. As to why these differences exist, a recent theory suggests that ovarian hormone fluctuations function as modulators of women's susceptibility to stress and that altered reactivity to stressors during different cycle phases plays a role in the etiology of depressive disorders. This hypothesis extends the Social Signal Transduction Theory of Depression which first and foremost relates depression to inflammation. They postulate a critical role of cytokines for understanding the pathogenesis of depression. Therefore, ovarian hormone fluctuations, but also inflammation in regard to MDD and PMDD and stress reactivity will be investigated in this study.

The investigators aim to investigate whether the intervention effect of pBFS-guided rTMS therapy targeting DLPFC is superior to the intervention effect of the traditional "5 cm-rule" guided rTMS therapy in patients with depressive disorders.
Xanamem is being developed as a potential treatment for symptomatic, early stages of Alzheimer's Disease (AD) and Major Depressive Disorder (MDD). This XanaCIDD Phase II study in MDD is to investigate the safety and efficacy of Xanamem™ in treating patients with cognitive and depressive symptoms. Trial participants will be randomized to either receive 10mg of Xanamem™ once daily or a Placebo at a 1:1 ratio in a double-blinded fashion.
