Filter by:Depression is a leading cause of disability worldwide, affecting roughly 21 million adults. Repetitive Negative Thought (RNT) has been identified as a potential maintaining factor in depression, such that those who exhibit higher degrees of RNT endorse greater symptoms. Research also suggests that the Default Mode Network (DMN), responsible for self-referential processing, plays an important role in depression wherein it has been linked to RNT. In depressed individuals, this network appears to be hyper-connected, or "too connected", within itself which, in turn, is thought to promote RNT. Half of depressed individuals are treatment-resistant, creating a critical need to identify more effective interventions derived from a better mechanistic understanding of the development and maintenance of depression. Non-invasive Transcranial-Focused Ultrasound Stimulation (tFUS) is promising for the treatment of depression. tFUS directs a low-intensity (nonthermal) focused ultrasound beam that passes safely through the skull. Compared to other noninvasive neuromodulation approaches, tFUS can target deeper brain regions with high spatial precision. The present study is an exploratory non-blinded single treatment study to investigate whether tFUS targeting a major hub of the DMN, the anterior-medial prefrontal cortex, can improve depression symptoms and reduce RNT. Twenty depressed individuals with high RNT (75th percentile) will complete up to eleven ultrasound sessions targeting the anterior medial prefrontal cortex, a hub of the brain's default mode network that has been found to be hyper-connected in depression. MRI scans will be obtained before the first and after the last ultrasound sessions. Based on previous literature, it is predicted that depression interview ratings and self-report symptoms will decrease after the intervention, and also that DMN connectivity will decrease following intervention.
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).
This two-armed randomized controlled trial aims to investigate the effectiveness of an emotion regulation intervention in individuals with and without depressive disorders. The study encompasses participants diagnosed with mild to moderate major depression or persistent depressive disorder and healthy controls without a current depressive disorder. Participants will be randomly assigned to either the intervention group, receiving a valence-specific emotion regulation intervention in daily life, or a monitoring-only control group. The valence-specific intervention supports the implementation of different emotion regulation strategies based on whether a person is experiencing mainly positive or negative emotions. In contrast, participants in the control group will solely monitor their positive and negative emotions and the strategies used to regulate them. Outcome measures include emotion regulation ability, self-efficacy, and strategy use, depressive symptoms, positive and negative affect, and emotion beliefs (controllability, usefulness). A second aim of the study is to compare beliefs about positive emotions and strategies to regulate them between individuals with and without current depressive disorders. Furthermore, the investigators aim to examine why individuals might choose unfavorable emotion regulation strategies even when feeling good. Therefore, another research question is, how emotion beliefs might explain emotion regulation strategy choice.
This study will test whether it is feasible to conduct a clinical trial of mirtazapine (an antidepressant tablet) in patients who have both depression and inflammatory bowel disease (IBD). The study design is a randomised controlled trial (a study in which people are allocated by chance to receive different interventions). The trial will compare mirtazapine against a placebo (dummy) tablet in 76 patients with both depression and IBD. The investigators will recruit outpatients aged 18 or over with a diagnosis of any IBD attending gastroenterology clinics. Either in person or remotely, patients will complete a brief screening questionnaire for depression. Those scoring positive for depression will be invited for a 15-minute interview for clinical depression. Those with clinical depression will be invited to take part. Participants will be randomly allocated by a computer to take either 1) mirtazapine tablet once at night for 12 weeks; or 2) placebo (dummy) tablet once at night for 12 weeks. The study is 'blinded', meaning neither patients nor the study team will know which medication they are taking. Throughout, participants will be able to access other treatments for depression, such as talking therapies. The investigators will measure how many people join the study; how many remain in the trial; how many complete treatment; how many tablets people take; and assess overall acceptability of the trial. Participants will complete brief questionnaires to measure their mental health and IBD symptoms after 4 weeks, 8 weeks, 12 weeks and 16 weeks. Participants will also provide blood samples and faecal samples to measure inflammation. If successful, this trial will support an application for a larger version of the study.
The aim of this Phase 2a study in patients with MDD is to assess safety and tolerability and preliminary antidepressant efficacy.
Approximately 240 eligible adult participants (≥18 years old) who meet Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) criteria for Major Depressive Disorder (MDD) will be enrolled. Participants will be randomly assigned to receive a single oral dose of Psilocybin 25 mg, Psilocybin 5 mg, or inactive placebo. The purpose of this study is to evaluate the efficacy, safety, and tolerability of Psilocybin 25 mg versus placebo in adults with MDD, as assessed by the difference between groups in change in depressive symptoms from Baseline to Day 43 post-dose, and to characterize the durability of initial treatment effect and subsequent response to optional Psilocybin 25 mg re-administration(s) during the 1-year Follow-up Period.
Major depressive disorder (MDD) is a chronic, recurring and potentially life-threatening illness that affects up to 10% of the population across the globe.Increasing evidence indicates a clear link between immune dysfunction and MDD.Moreover, an activation of inflammatory pathways is associated to a lack of clinical response to antidepressants. Thus, the regulation of inflammation represents a potential approach to modulate the link between the living environment and antidepressant outcome. Light therapy combined with sleep deprivation hastens recovery, with benefits that can be perceived by patients during the first week of treatment. Alteration of the sleep-wake cycle and of sleep structure are core symptoms of MDD.The aims of the present project are (i) to show that neural plasticity and the environmental context are moderating factors of the therapeutic outcome of immune modulation and (ii) to exploit their interplay to set up novel and effective therapeutic strategies for MDD.This is a observational prospective study with non-invasive add-on procedures (Magnetic Resonance without contrast). In this study, 60 patients with a depressive episode in course of MDD and treated with a chronobiological intervention including total sleep deprivation (TSD) + light therapy (LT), as performed in clinical practice, will be studied. All participants enrolled in the study will receive Treatment As Usual (TAU), i.e., pharmacotherapy, chronobiological intervention plus clinical management. Drug prescription will be performed during the clinical management sessions.The study will have a total duration of 24 months. Each subject will participate in the study for 6 months, will undergo Magnetic Resonance Imaging (MRI) and clinical evaluation at baseline, after one week of chronobiological treatment and at 6 months follow-up.
Major depressive disorder (MDD) is a chronic, recurring and potentially life-threatening illness that affects up to 10% of the population across the globe.It posits that the increase in serotonin levels induced by Selective Serotonin Reuptake Inhibitors (SSRIs) does not affect mood per se, but enhances brain plasticity and thus amplifies the influence of the environment on the individual. Thus, SSRI treatment has not a univocal effect but, in a favorable environment, it would lead to a reduction of symptoms while in a stressful environment might lead to a worse prognosis.Such innovative view opens new perspectives on how to improve SSRI efficacy by controlling the environment. However, often it is not possible to act on the quality of the living environment because of constraints due to patient's personal history and unchangeable life circumstances. In these cases, the pharmacological modulation of the factors underlying the link between living environment and SSRI efficacy represents a novel and desirable strategy to improve treatment outcome even in patients living in adverse conditions, which are very common in depressed patients. Inflammatory levels are markedly affected by the socioeconomic status and thus by the quality of the living environment. The hypothesis of the present project is that inflammation mediates the influence of the environment on SSRI outcome.Therefore, the control of inflammatory levels is a promising strategy to improve treatment efficacy and overcome the limited SSRI efficacy, especially when administered in patients living in adverse conditions. A further hypothesis is that the influence of the environment on inflammation, in turn affecting SSRI efficacy, occurs through epigenetic modifications. Therefore, the project aims at developing a pharmaco-epigenetic approach as effective treatment for MDD. In addition, through neuroimaging investigations, it will provide important information about functional and structural brain modifications associated to SSRI efficacy in patients. Both males and females will be considered because MDD is twice as common in women than men, suggesting that different mechanisms may underlie the psychopathology in the two sexes.
The study's primary objective is to evaluate the effectiveness of Tinazidine compared to Zolpidem in enhancing sleep quality, with secondary objectives including the assessment of adverse effects, safety profile, and patient tolerance with each treatment. The trial will be conducted as a double-blind RCT, with participants randomly assigned to receive either Tinazidine (0.1 mg/Kg/HS) or Zolpidem 10 mg HS, for 12 weeks. Eligible participants, aged 18-60 years, diagnosed with primary insomnia as per DSM-5 criteria, will be recruited from an outpatient sleep clinic affiliated with Al-Masara Hospital. Data on sleep quality, and side effects, will be collected using the Sleep Pittsburgh Sleep Quality Index (PSQI), Clinical Global Impression (CGI), sleep diaries, actigraphy, polysomnography, and regular clinical interview though OPD follow-up visits. The primary outcome considered was the mean global PSQI score before and after the treatment. The primary outcome will be measured four times (baseline, 4 weeks, 8 weeks, and 12 weeks), We considered an attrition rate (dropout/lost follow-up) of 10%. Therefore, the sample size is 90 subjects (45 in each group). Group comparisons for mean scores will be conducted using independent samples t-tests, and within-group comparisons will be assessed using paired samples t-tests. Changes in sleep quality over time between treatment groups will be evaluated using repeated measures ANOVA. Associations between categorical variables will be examined using Chi-square tests (including Fisher's exact or Likelihood ratio tests as appropriate). Statistical significance will be considered for p-values less than 0.05. All analyses will be performed using IBM SPSS Statistics (Version 29.0). The findings of this study seek to elucidate the comparative efficacy and safety profiles of Tizanidine and Zolpidem in treating primary insomnia. The study aims to offer insights into the effectiveness of Tizanidine versus Zolpidem in improving sleep quality among patients with primary insomnia. Through the evaluation of efficacy, adverse effects, and safety profiles. This study aims to inform clinicians and healthcare practitioners about the optimal treatment choices for individuals with primary insomnia.
The prefrontal cortex, although well established as an efficacious target for the treatment of major depressive disorder (MDD), has recently come into favour as a therapeutic target for alcohol use disorders (AUD). Depressive symptoms are also highly prevalent in individuals with AUD. A number of cognitive and psychological processes stemming from the prefrontal cortex, a common treatment target for repetitive transcranial magnetic stimulation (rTMS), are disrupted in both MDD and AUD. The proposed study will enhance the development of theta burst stimulation (TBS) as a new intervention for AUD in the context of depressive symptoms and uses integrated TMS-EEG to identify neurophysiological targets of executive dysfunction in this disorder.
