Filter by:Anhedonia, the inability to seek-out and experience pleasure, is a common symptom in depression that predicts treatment-resistance and is sometimes exacerbated by first-line antidepressants. In our previous research, we found that anhedonia decreases goal-directed behavior and its related neural activity. In this study, we will investigate target engagement from five-consecutive days of stimulation for participants that are within a unipolar major depressive episode and also have high symptoms of anhedonia.
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.
The goal of this clinical trial is to compare the effect of three level interventions(universal prevention, selective prevention and targeted prevention) in elderly depression and find out the most efficient intervention path. The main questions it aims to answer are: - Whether the pre-disease three-level prevention model (universal prevention, selective prevention and targeted prevention) is applicable for elderly depression in urban communities; - Which level of intervention has the best effect on elderly depression. Participants will be given the following treatments: - Level 1 intervention(universal prevention): Health education related to depression to strengthen the participants' self-care skills to reduce sub-health risk factors. - Level 2 intervention(selective prevention): Psychosocial interventions (including but not limited to cognitive behavioral therapy, acceptance commitment therapy, mindfulness training) aimed at risk factors to prevent more severe depressive symptoms. - Level 3 intervention(targeted prevention): Therapeutic psychosocial interventions (including but not limited to cognitive behavioral therapy, acceptance commitment therapy, mindfulness training) to reduce patients' depressive symptoms. Researchers will compare control group to see if the three levels of intervention have a significant effect.
Patients belonging to Group 1 (Major Depression) and 2 (Bipolar Disorder) will be tested with psychometric and functional scales at baseline (T0) and after 4 weeks of pharmacological therapy (T1), to evaluate clinical and functional response to treatment. MDD patients will be screened for the lifetime and recent occurrence of clinically meaningful suicidal ideation and behavior prior to recruitment (-T1). Moreover, in the MDD group, the emergence of clinically meaningful suicidal ideation and behavior will be evaluated at the baseline (T0) and after 4 weeks (T1) by means of the C-SSRS, accordingly to the routine clinical practice. Furtherly, to accomplish the pursues of this research, the two groups will undergo neuroimaging evaluation and a blood collection at the two timepoints for measuring the expression of ncRNA before and after treatment. Meanwhile, a lumbar puncture (LP) for CSF collection will be carried out at the baseline, measuring central levels of Negr-1 and other biomarkers of neurotropism potentially related to the aforementioned role of Negr1 in MDD. Group 3 will be comprehensive of 10 subjects without current or previous diagnosis of psychiatric disorders (healthy controls), who will be evaluated at baseline with psychometric and functional scales, neuroimaging and blood samples collection for ncRNA. Data obtained by the multimodal assessment of HCs at the baseline will be employed as normalization features in the statistical analysis of patients' data.
Post-partum depression (PPD) is a prevalent subtype of major depressive disorder that causes a significant distress to the woman and substantial impact on the whole family. Many studies implicate the glutamatergic system in pathological processes relevant to PPD disorders. There is evidence that cell adhesion molecules (CAMs) play a key role in how glutamatergic circuits wire up during development and how glutamatergic synapses, once formed, operate. However, it is unclear how dysregulation in diverse CAMs alter glutamatergic circuitries responsible for emotional and social behavior. Here, the investigators propose to evaluate the molecular and neurobiological underpinnings of PPD focusing on CAMs at glutamatergic synapses by using an integrated approach from mouse models to human patients. Moreover, the investigators will also perform a pilot study to investigate the impact of selective antidepressants, known to be linked to CAMs, in both human and mice.
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.
High-frequency repetitive transcranial magnetic stimulation of the primary motor cortex has shown its effect on refractory neuropathic pain, and rTMS of the dorsolateral prefrontal cortex is commonly used for treatment-resistant depression. The treatment for patients suffering from neuropathic pain and depression, concomitantly, still needs to be studied, as there are some specificities in both symptoms and brain functional MRI.
This is an open-label, parallel-group study to evaluate the safety and efficacy of ropanicant in participants with moderate to severe Major Depressive Disorder (MDD).
This is an open-label study, in which all participants receives an active treatment with repetitive transcranial magnetic stimulation (rTMS) according to clinical protocol. The aim with this pilotstudy is to investigate the feasibility to perform a trial of low-frequency rTMS on treatment-resistant depression in adolescents. The study includes adolescents 13-19 years old, with average to severe depression.
The aim of this hybrid (Effectiveness-Implementation) cluster randomised controlled clinical trial is to test the feasibility of implementing an age-appropriate electronic version of the WHO Mental Health Gap Action Programme Intervention Guide (emhGAP-Age) in routine home-based care of older Nigerians with depression. The main questions it aims to answer are: 1. Whether the emhGAP-Age demonstrate sufficient signals of effectiveness in the identification and home management of late life depression to permit for further exploration in a fully powered clinical trial? 2. What are the logistical, programmatic, and operational requirements for a home-delivered emhGAP-Age in a sample of older people with depression in Nigeria? Consenting older participants with depression in the intervention arm will receive treatment based on emhGAP-Age which consists of; - Adapted electronic generic version of the WHO Mental Health Gap Action Programme Intervention Guide (emhGAP-IG) - Adapted Problem-Solving Therapy (PST-PC) - Support/supervision of providers - Links to social support resources. Researchers will compare with treatment based on the basic specification in the generic emhGAP-IG (consisting of basic psychoeducation and stress reduction) for effects on depression remission.
