Filter by:The aim of this study is to test if combining the antidepressant Citalopram with Pentoxifylline (PTX), a medicine with anti-inflammatory and phosphodiesterase inhibitory properties, enhanced antidepressant efficacy in adult patients with major depressive disorder (MDD) when compared to Citalopram alone.
The investigators compare the primary and secondary outcome measures using accelerated intermittent theta burst stimulation (aiTBS, 20 sessions active and 20 sessions sham in a counterbalanced crossover design) to treat depressive symptoms with 2 parallel arms of intervention: personalized (stimulation position based on participants' brain networks) vs conventional (stimulation in F3 position of the 10-20 EEG cap) aiTBS.
This trial aims to examine the safety and efficacy of small (2mg) sub-hallucinogenic doses of psilocybin in people with Major Depressive Disorder.
This study aims to examine the effect of ketamine in decreasing the risk of suicide in patients with depression and its effectiveness as an antidepressant agent.
Novel invasive neurostimulation stimulation strategies through neurosurgical interventions are emerging as a promising therapeutical strategy for major depressive disorder. These have been applied mostly to the anterior cingulate cortex, but other limbic brain regions have shown promise as anatomical targets for new neurostimulation strategies. The researchers seek to study neural activity in limbic brain areas implicated in decision behavior and mood regulation to identify novel targets for treatment through electrical stimulation. To do this, the study team will record local field potentials (LFPs) from the orbitofrontal cortex, hippocampus and amygdala of epilepsy participants undergoing invasive monitoring (intracranial encephalography, iEEG) during choice behavior. Leveraging the high co-morbidity of depression and intractable epilepsy (33-50%), neural responses will be compared to reward across depression status to identify abnormal responses in depression. Finally, the researchers will use these as biomarkers to guide development of neurostimulation strategies for the treatment of depression.
If not treated sufficiently, Major Depression tends to take a recurrent or chronic lifetime course that is associated with a significantly increased risk for physical and neurodegenerative disorders. In England, Increasing Access to Psychological Therapies (IAPT) services provide evidence-based treatment for patients with common mental disorder with an access rate intended to rise to 25% of this population by 2021. However, about 50% of the depressed patients who come to the end of this pathway, have not responded sufficiently. Mindfulness-Based Cognitive Therapy, a treatment combining training in mindfulness meditation and components from cognitive therapy, has previously been shown to be effective in treatment non-responders, but further evidence is needed to establish this finding more definitively and to see whether positive effects can be achieved within the stepped care approach of IAPT. In order to address these issues, this study will investigate whether MBCT can effectively reduce symptoms and lead to sustained recovery in patients suffering from Major Depressive Disorder who have not sufficiently responded to high-intensity evidence-based therapy and have thus come to the end of the Increasing Access to Psychological Therapies (IAPT) care pathway. It will also test whether the introduction of this treatment can reduce subsequent service use. The investigators will randomly allocate 234 patients who have not sufficiently responded to IAPT high-intensity therapy to take part either in MBCT or to continue with TAU in a three-centre (London, Exeter, Sussex) RCT. Reductions in depression symptomatology will be assessed using the Patient Health Questionnaire-9, a standard measure of the severity of depression used in IAPT treatment monitoring, at 10-week (secondary outcome) and 34-week follow-up post-randomisation (primary outcome). Service-use information will be collected using the Adults Service Use Schedule. If successful, the current project would provide the necessary evidence base for the introduction of MBCT for IAPT high-intensity non-responders.
The primary objectives of this clinical investigation are to (1) determine the feasibility of joining psilocybin treatment with CBT (cognitive-behavioral therapy) for patients with depression, (2) optimize CBT to most effectively integrate the psilocybin experience with psychotherapy and (3) determine the initial efficacy of psilocybin as an adjunct to cognitive-behavioral therapy (CBT) for major depressive disorder. Psilocybin will be administered orally in two doses during the course of 12 sessions of CBT to eligible study participants - a 10mg dose following the third session and a 25mg dose following the sixth session. Participants will be in active treatment for the first 4 months (psilocybin + CBT) of the study and then followed for an additional 3-months following the termination of CBT.
Repetitive Transcranial magnetic stimulation (TMS) uses magnetic fields to modulate brain activity. A novel form of repetitive TMS (rTMS), intermittent theta burst stimulation (iTBS), has emerged as a promising new treatment for depression. This technique may be advantageous due to its very short duration and potentially stronger effect on brain activity in comparison with standard rTMS. However, the exact effect of iTBS on the activity of the brain in clinical populations remains poorly understood. This project aims to improve understanding of the mechanisms of action of iTBS by comparing its neuronal effect to sham treatment in 22 individuals with a diagnosis of major depressive episode, using positron emission tomography (PET) and magnetic resonance imaging (MRI) in a double-blind cross-over experiment, followed by a 6-week daily treatment course of iTBS.
Depression is a highly prevalent condition characterized by persistent low mood, energy, and activity that can affect one's thoughts, mood, behavior, and sense of well-being. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive neuromodulatory technique, is an effective treatment for depression when targeting the dorsolateral prefrontal cortex (dlPFC) of the central executive network (CEN). However, remission rates are suboptimal and individual methods to target the dlPFC are lacking. In this study, we will enroll 50 patients with major depression and in a single rTMS 'dose,' prospective, randomized, double-blind, cross-over design will assess whether rTMS targeted to an individual's central executive network (CEN) assessed by single pulse TMS can enhance network modulation. If successful, this work will lead to a clinical rTMS trial comparing this personalized targeting approach against standard rTMS.
Depression is a recurrent debilitating psychiatric disorder with a lifetime prevalence of 20%. Even though antidepressants and psychotherapy are often effective, a substantial proportion of patients does not respond to currently used evidence-based treatments. The heterogeneous nature of depressive symptoms is a major obstacle for the development of novel effective treatments, and targeted treatments for depression are currently lacking. The investigators propose a targeted disease-modifying treatment for the clinically distinct form of depression related to childhood trauma (CT, emotional/ physical/sexual abuse or neglect before the age of18). CT-related depression is critically different from non-CT depression: it emerges earlier in life with more severe and recurrent symptoms and less favorable responses to treatment. With an average 25% prevalence in depression, there is a large and unmet need for therapeutic strategies to treat depression in individuals with substantial CT. The GR is the major cortisol receptor in the brain and rodent studies have shown that GR blockade at adult age can reverse the effects of early-life adversity. Therefore, GR blockade is a potential novel treatment for CT-related depression but this has never been investigated. Based on the underlying stress neurobiology, the aim is to investigate whether the biological sequelae of excessive stress due to CT can be targeted by blocking the glucocorticoid receptor (GR) using the generic drug mifepristone.
