Filter by:The study consists of an open label trial designed to treat adult depression with TBS. Our aim is to build capacity in neuroimaging analyses by performing magnetic resonance imaging (MRI) assessments at baseline and after 7-10 days of treatment onset in 70 patients. The scientific goal is to test a hypothesis about treatment action: that TBS will reduce negative bias (which causally maintains negative mood) after 1 week of treatment, and patients who show this neurocognitive change will be the ones who go on to respond clinically after 6 weeks.
This is a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of 10, 20, 40 and 60 mg oral PRAX-114 compared to placebo in the treatment of adults with MDD. The study will enroll participants on adjunctive treatment who had an inadequate response to their current antidepressant treatment and participants not currently being treated with pharmacotherapy for MDD. A sub-study to investigate the pharmacokinetics (PK) of PRAX-114 and metabolites when dosed in the evening in participants with MDD will be conducted in a subset of participants at selected research sites with serial PK sampling capabilities.
The primary objective of this study is to collect insights from first responders and military personnel on their need for, use of, and interest in physical and/or mental health medical marijuana or psychedelic-assisted therapy programs. These preliminary data will help to inform and guide the development of a larger patient-oriented study and the design of a clinical program geared towards enhancing therapy treatments for first responders and military personnel.
The purpose of the study is to investigate a short-term treatment option for major depressive disorders by administering nitrous oxide gas. At this time, the main purpose is to complete a feasibility study with 40 participants suffering from treatment-resistant depression. Participants will be randomized to (1) Study group: Nitrous oxide (inhaled) + solution of saline (injected) and the (2) Control group: Oxygen (inhaled) + Midazolam (injected) as an Active Placebo.
This cohort study is a large population-based study in the UK to determine the risks of comorbid mental health conditions (including depression, anxiety and other potential psychological complications of vitiligo) in adults with vitiligo compared to controls and to evaluate whether the relative risks may vary by different ethnicity.
Over 50% of patients with major depressive disorder (MDD) do not respond to initial treatment and relapse is common. In particular, comorbid depression and anxiety disorders are associated with more treatment resistance. Thus, there is a great need for novel, more targeted treatments. Transcranial direct current stimulation (tDCS) is a novel intervention that can be used to causally target neural excitability and plasticity in brain regions/circuits implicated in regulating mood and anxiety and emerging evidence suggests that it reduces threat sensitivity. Here the investigators propose to use tDCS to target threat sensitivity as a core symptom of anxious depression to determine if the investigators can engage the neural circuits that are treatment targets. Following the administration of a single dose of anxiolytic or antidepressant treatment, early changes in emotional processing have been observed in healthy people and clinical groups. Among patients, acute cognitive effects - such as a reduction in threat sensitivity - have been shown to predict response to drug and behavioral treatments. Functional magnetic resonance imaging (fMRI) studies have confirmed hyperactive amygdala and/or hypoactive prefrontal activity in patients, indicating an imbalance of activity within this cortico-limbic circuit that sub-serves threat identification (amygdala) and top-down control (prefrontal). Specifically, treatments aiming to remediate prefrontal/ amygdala dysfunction could be a critical target in patients exhibiting these deficits. Several clinical trials have shown that administration of frontal cortex tDCS is a potentially effective treatment for MDD. However, underlying mechanisms of action are unclear. To meet this gap, the investigators propose an experimental medicine study (target identification and initial target engagement paths) where 141 volunteers with anxious MDD will be randomized to receive a single session of active or sham tDCS in a parallel design. Threat sensitivity will be measured using task and resting state fMRI and potentiated startle electrophysiology. Preliminary data suggest reductions in behavioral threat sensitivity from a single session of frontal tDCS. This was followed up with an fMRI study which found that a single session of active vs sham frontal tDCS reduced amygdala response to fearful faces whilst simultaneously increasing frontal attentional control signals. This provides evidence that modulating activity in the frontal cortex inhibits amygdala response to threat, highlighting a potential neural mechanism for the behavioral reduction in threat sensitivity. In addition, this offers initial mechanistic insights into the efficacy of tDCS in clinical trials for the treatment of MDD and anxiety disorders, suggesting that threat sensitivity may be a suitable cognitive target. The current proposal builds on this to establish acute effects of frontal tDCS on amygdala response to threat (primary aim), frontoparietal response to threat (secondary aim), startle response under threat (secondary aim) and approach-avoidance-conflict (exploratory aim). The ultimate aim is to apply these multi-level acute findings to mechanistic clinical trials of tDCS, to test their prediction of treatment response (full model path) and improve patient outcomes.
The primary objective of the study is to evaluate the feasibility of eliciting continuous narrative speech in different neurodegenerative and psychiatric indications, using remote, self-administered speech tasks, as measured by the average length of speech elicitation for each speech task during the first week of self-assessment. Secondary objectives include (1) evaluating the reliability of speech tasks in the remote self-administered setting, as measured by the intra- and inter-subject variance; (2) accessing the adherence of speech tasks in this setting, as measured by the subject average fraction of days during the first week, where at least one task response is submitted; (3) evaluating the feasibility of using speech tasks in the setting of a telemedicine videoconference, as measured by the average length of speech elicited in each group; (4) evaluate whether a set of acoustic and linguistic patterns can detect each indication, compare to either a control group or all other indications, as measured by the area under the receiver operating characteristic curve (AUC), sensitivity, specificity and Cohen's kappa of the relevant binary classifier; (5) evaluating how the performance of such algorithms can be impacted by speaker and environment covariates, as measured by the Kendall rank correlation coefficient of the AUC of each classifier and each of age group, gender and speech-to-reverberation modulation energy ratio.
This study is open to adults between 18 and 65 years of age who have depression (major depressive disorder). People with a current depressive episode lasting between 2 months and one and a half years can join the study. This study is for people for whom existing treatments for depression do not work sufficiently. The purpose of this study is to test how well a medicine called BI 1569912 is tolerated and whether it may help people with depression. It is planned to test 4 different dosages of BI 1569912 in this study. Each participant gets either one BI 1569912 dosage or placebo. It is decided randomly, which means by chance, who gets which treatment. Participants take BI 1569912 or placebo as tablets once during the study. Placebo tablets look like BI 1569912 tablets but do not contain any medicine. Participants also continue taking their usual medicine for depression throughout the study. Participants are in the study for about 5 weeks. During this time, they visit the study site 4 times, with a stay at the study site for 9 days. The doctors check the health of the participants and note any health problems that could have been caused by BI 1569912. The participants fill in questionnaires about their depression symptoms.
TRAIT-RS is an observational study to evaluate ongoing treatment response stability to standard of care antidepressant treatments (ADTs) among individuals who met criteria for Major Depressive Disorder (MDD) and completed the Tracking Response to Antidepressants in Advance of Investigational Trials (TRAIT) study (NCT04748276).
The purpose of this study is to determine the safety, tolerability, and feasibility of psilocybin therapy for depression and anxiety in people with Parkinson's disease.
