Laughter Yoga Intervention for People With Major Depressive Disorder
Major Depressive DisorderMood Disorder1 moreThe present study will adopt a non-blinded parallel-group randomized controlled trial design that involves a Laughter Yoga group (intervention) and a treatment-as-usual group (Control). It aims to determine the feasibility of using LY intervention on patients with Major depressive disorder (MDD), and also to evaluate the potential effect of the intervention on comorbid depression, anxiety and stress for these patients. It is hypothesized that, LY group, as compared to the TAU group, will have significantly lower symptoms of depression, anxiety and stress, but greater improvements in self-reported mental health/physical health-related quality of life immediately post intervention and at 3 months' follow-up.
The Effects of Progressive Muscle Relaxation Therapy in Patients With Schizophrenia
Affective DisordersPsychotic DisorderThis study applied a randomized parallel case-controlled design. The study purpose was to evaluate the effects of progressive muscle relaxation on anxiety, psychiatric symptoms and quality of life among patients with chronic schizophrenia compared with an active control.
Effects of Seven Day Prucalopride Administration in Healthy Volunteers
Molecular Mechanisms of Pharmacological ActionDepression5 moreThis study will investigate whether seven days administration of the serotonin receptor subtype 4 (5-HT4) partial agonist prucalopride has effects on emotional processing and neural activity in healthy volunteers, compared to placebo administration. Using an experimental medicine approach, the effects of prucalopride on cognitive biomarkers of antidepressant action will be characterised. In a double-blind design, participants will be randomised to receive seven days administration of either prucalopride (1mg daily) or placebo. All participants will come for a Screening visit, Research Visit One (including an MRI scan) and Research Visit Two (including measures of emotional processing and non-emotional cognition). The primary study hypothesis is that seven-day prucalopride administration will have positive effects on emotional processing and reward sensitivity. A secondary hypothesis is that seven-day prucalopride administration will alter non-emotional cognition. Finally, the study will test the hypothesis that seven day prucalopride administration will alter neural activity during an emotional faces task and a memory task.
Low Intensity Focused Ultrasound for Emotion Regulation
Psychiatric DisorderAnxiety Disorders4 moreAmygdala is highly involved in emotional response, emotional reactivity and anxiety. Amygdala functions are therefore involved in a wide range of psychiatric disorders including generalized and social anxiety, specific phobia, obsessive compulsive disorder and posttraumatic stress disorder. Therefore, potential clinical implications of amygdala stimulation are great. However, to date, such efforts have been limited by the inability of non-invasive neuromodulation techniques (e.g. transcranial magnetic stimulation - TMS) to reach the amygdala and the highly invasive (i.e. neurosurgical) nature of methods (e.g. deep brain stimulation - DBS) which can, but to our knowledge has rarely been used, target these areas. In order to overcome these current limitations, study invesitgators propose the use of low intensity focused ultrasound pulsation (LIFUP) to affect amygdala activity to improve emotion regulation.
Online Training for Addressing Perinatal Depression
Mood DisordersAnxiety DisordersThe study team is developing an e-learning course to train obstetric providers to address perinatal mood and anxiety disorders. The study team will conduct a formative evaluation of the e-learning course with 10 obstetric providers and revise/refine the course based on feedback and then conduct a summative evaluation using a cluster Randomized Controlled Trial (RCT). The three-arm cluster RCT will evaluate the effectiveness of 1) a virtual implementation protocol and e-learning/toolkit as compared to 2) e-learning/toolkit alone as compared to 3) treatment-as-usual. Effectiveness will be evaluated based on rates and quality of care for perinatal mood and anxiety disorders. Using 2:2:1 randomization, the study team will randomize a minimum of 15 to a maximum of 25 obstetric practices into three groups: (1) virtual implementation protocol plus e-learning/toolkit (n=6 to 10); (2) e-learning/toolkit alone (n=6 to 10); and (3) treatment-as-usual (n=3 to 5), which will yield a maximum of 1000 patient charts evaluated for care received from obstetric providers in the randomized practices. Charts from 40 patients per practice will be evaluated at 3 different time points.

SchizophreniaSchizotypal and Delusional Disorders2 moreThe purpose of this study is to investigate the efficacy of IPS in Denmark and compare effects of 1. Individual Placement and Support (IPS) vs. 2. IPS + cognitive remediation and work-related social skills training vs. 3. standard intervention, among individuals with severe mental illness.
Interaction Between Reboxetine and 3,4-Methylenedioxymethamphetamine: Pharmacodynamics (PD) and...
Mood DisorderSubstance-related Disorders1 moreMDMA releases dopamine, serotonin, and norepinephrine in the brain. Serotonin uptake inhibitors have been shown to interact with 3,4-Methylenedioxymethamphetamine (MDMA) and to decrease its psychoactive and cardiovascular stimulant effects. This finding indicates that MDMA acts in part by releasing serotonin through the serotonin uptake site. However, in vitro studies show that MDMA binds more potently to the norepinephrine uptake site that to the the serotonin or dopamine uptake transporter. In addition, norepinephrine uptake site blockers such antidepressant drugs attenuate some of the behavioral effects of MDMA in animals. These preclinical data indicate that norepinephrine may also contribute to the response to MDMA in humans. To test this hypothesis this study evaluates the interacting effects of the selective norepinephrine transporter inhibitor reboxetine on the subjective and cardiovascular stimulant effects of MDMA in healthy volunteers.
Intranasal Administration of Neuropeptide Y in Healthy Male Volunteers
Mood DisorderAnxiety DisordersThere is growing evidence that neuropeptides act as neuronal messengers in the brain and have diverse functions that may include the regulation of mood and behavior. For example, neuropeptide Y (NPY) is thought to play a role in the adaptive stress response. The therapeutic application of neuropeptides for psychiatric disorders has been limited by difficult and unreliable penetration of the blood-brain barrier (BBB). However, recent data suggest that intranasal administration may provide a means of effectively delivering some of these neuropeptides to the brain. Thus far it is unclear if this is the case for NPY. The aims of this project are: To evaluate, in 15 healthy male volunteers aged 25-45, the effect of intranasal NPY administration (0, 50 and 100 nmol) on its levels in cerebrospinal fluid (CSF), measured by means of lumbar puncture using an intraspinal catheter between L4 and L5, and in plasma, measured using an intravenous catheter in the forearm. One of the three treatments will be administered to each participant in a double-blind fashion. The 0 nmol condition will serve as the placebo control. To test the effect of intranasal NPY administration on mood and anxiety.
Pharmacological Interaction Between Doxazosin and Methylenedioxymethamphetamine (MDMA)
Mood DisorderSubstance-Related Disorders1 moreThe purpose of this study is to determinate the effect of a pre-treatment with doxazosin, a alpha1-adrenergic receptor blocker, on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy"). The investigators hypothesize that doxazosin will attenuate the cardiovascular and subjective response to MDMA.
Pharmacological Interaction Between Pindolol and MDMA (3,4-Methylenedioxymethamphetamine)
Mood DisorderSubstance-Related Disorders1 moreMDMA (3,4-Methylenedioxymethamphetamine, "Ecstasy") produces tachycardia, hypertension, hyperthermia, and other acute adverse effects. Ecstasy use has also been associated with rare cardio- and cerebrovascular complications. The role of beta-blockers in the treatment of cardiovascular and adverse effects of MDMA is unknown.
