Filter by:Placebo groups in clinical trials on depression show impressive improvements. Yet, there is little research on the mechanism underlying this effect. The aim of this study is to assess how patients' treatment expectations modulate the placebo treatment effects. We expect that patients' treatment expectation determines placebo responses and treatment outcomes, and that this expectation is influenced by the disorder explanations (information about the illness models) typically provided during the initial medical encounters that precede treatment. In the study we aim to manipulate depressed patients' expectations by providing two different clinician-delivered illness and treatment rationales (biological/ psychological). Patients will then receive placebo treatment (pharmacological/ psychological), that is either congruent or incongruent with the previously communicated treatment rationale. Hypotheses: 1. Providing a treatment-congruent treatment rationale leads to a better outcome than providing treatment-incongruent rationales. 2. Treatment-congruent explanations reduce the risk of side effect development, in particular in the medication arm. 3. Inter-individual differences in the effect of provided treatment rationale are associated with pre-treatment experiences and expectations, depression severity and comorbid anxiety.
This project will examine changes in metabolism and depressive symptoms after receiving CBT-I in 30 subjects with insomnia disorder and MDD.
The aim of this study is to assess the changes in retinal nerve fiber layer due to SSRI treatment in first-attack major depressive patients.
The investigators will evaluate a brief group-based cognitive-behavioral treatment program for adolescents aged 13-17 years with internalizing problems.
In a 12 week randomly controlled open trial 102 participants with symptoms of depression and/or anxiety will be exposed to either aerobic high intensity training (HIT) or relaxation therapy. Cognitive functions, biomarkers, psychiatric symptom scales and physical status will be collected at baseline, after 12 weeks and after a year. Depression and anxiety will be measured twice during the intervention period.
The present aim of the study is to to adapt an established, manualized enhanced Group CBT (CBT-E) for seniors to a telehealth format, which will allow us to offer the group virtually during the COVID-19 pandemic.
Severe childhood adversity accounts for a large portion of psychiatric illness, and an increased risk for major depressive disorder (MDD). For some individuals, childhood adversity has negative psychological and medical consequences; others preserve mental and physical health despite such experiences (they are resilient). In spite of this, little is known about the neurobiological mechanisms related to childhood adversity, especially oxidative stress abnormalities in the brain. To fill this gap, this study combines functional, structural, and molecular imaging approaches to examine the role of oxidative stress abnormalities related to childhood adversity.
The aim of this study is to improve the treatment effect for outpatients with depression by adding regular daily morning daylight exposure to their treatment with antidepressants. Patients will wear a personal light tracker to keep them motivated. Our hypothesis is that patients daily exposed to morning daylight, as a supplement to standard treatment for depression, will achieve significantly higher antidepressant effect that patients receiving standard treatment alone. Furthermore, we hypothesize that they will experience improved well-being and sleep.
The goal of this fixed order, open-label, dose-escalation study is to investigate the safety and efficacy of specific doses of dimethyltryptamine (DMT) in humans.
A 6-cohort single ascending dose (SAD) study will be conducted in healthy volunteers utilizing a slow-infusion intravenous (IV) route of administration. Standard safety, pharmacokinetics (PK) and qEEG monitoring will be evaluated at all dose levels. Subsequently, a 2-cohort multiple ascending dose (MAD) study will be conducted. Doses will be administered on days 1, 4, 8, and 11. Standard safety parameters will be monitored, and PK will be evaluated at all dose levels. Finally, a single-cohort group with received a single dose by slow-infusion IV and have PK samples collected from both blood and cerebrospinal fluid (CSF).
