Filter by:The aim of this study is to evaluate the efficacy and acceptability of the website "ich bin alles" (https://www.ich-bin-alles.de/) to improve depression literacy (knowledge about depression, which aid the recognition, treatment or prevention of depression) in parents of healthy adolescents without a mental health condition. The investigators will examine whether the website improves depression literacy in parents of adolescents aged 12 to 18 years without a mental health condition. The investigators will also assess the acceptability of the website among the participants.
A growing body of evidence has highlighted the role of inflammation and phosphodiesterases (PDE)-related pathways in the pathogenesis of neuropsychiatric illnesses such as depression/mood disorders. Herein, we aimed to evaluate the therapeutic benefits of pentoxifylline (PTX) in the treatment of therapy-resistant depression (TRD) in adult patients with bipolar depression.
This is a multi-centre, observational, non-interventional study, which will prospectively collect clinical and socio-demographic data from patients with depression occurred after COVID 19 in real clinical settings during 8 weeks of treatment. 10 clinics and 10 of psychiatrists and neurologists across the country will participate in the study and it is estimated that each investigating physician will enroll 10 patients.
To examine the efficacy of Almond Therapy compared to Treatment as Usual when used in addition to an approved version of intranasal esketamine.
To determine the efficacy of a 2-week daily programme (10 sessions) of HD-tDCS to augment antidepressant therapy in subjects with late-life depression who had residual depressive symptoms despite adequate dosage and duration of antidepressant therapy.
The main goal is to assess the efficacy of the Unified Protocol for the Transdiagnostic Treatment (UP-A; Ehrenreich-May et al., 2018) for Adolescents with moderate emotional symptoms in educational settings The goal is to prevent emotional symptoms and improve the socio-emotional adjustment.
The purpose of this proposal is to test the efficacy of yoga as a mind and body intervention to decrease stress, anxiety, and depression in parents of critically ill neonates hospitalized in the Seattle Children's and University of Washington neonatal intensive care units (NICUs).
The aim of this study is to assess the impact of ketamine on aesthetic perception and processing. This study assesses the role of these effects in facilitating ketamine's antidepressant properties, with a focus on anhedonia. To address this aim, 25 patients with major depressive disorder and 35 healthy controls will be assessed twice with magnetic resonance imaging, once after administration of intravenous ketamine (subanesthetic dose) and once after administration of placebo.This study has a single-center, placebo-controlled, cross-over study design. During MRI, structural, resting state, and functional imaging will be performed. Functional imaging will comprise aesthetic processing, reward, and sexual arousal paradigms. In addition, various neuropsychological scales assessing depressive symptoms, anhedonia, and aesthetic processing will be performed. Eligibility for participation will be assessed during a screening visit, a follow up visit will end study participation.
Ghrelin is a stomach-derived hormone and the only known circulating peptide that stimulates appetite. Animal studies have conclusively shown that ghrelin increases dopaminergic neurotransmission and, thereby, enhances effort. However, similar evidence on the putative role of ghrelin in humans is still lacking. Here, the investigators propose to conduct a [11C]-raclopride PET/MR study after intravenous administration of ghrelin vs. saline in healthy individuals. First, during an intake visit, the investigators will assess fasting blood levels of hormones involved in appetitive behavior such as ghrelin, leptin, and insulin. In addition, the investigators will conduct a set of tasks that have been associated with dopamine function (i.e., effort and reinforcement learning). Second, the investigators will assess the effects of intravenous administration of ghrelin on dopamine signaling using a double-blind randomized cross-over design. To this end, participants will be infused with ghrelin (vs. saline) while we determine dopamine release (via PET imaging) and assess cerebral blood flow and functional connectivity at rest (via concurrent MR imaging). Furthermore, the investigators will conduct an instrumental motivation task (IMT) where participants have to exert physical effort to obtain rewards. Based on preclinical studies and indirect evidence from human studies, the investigators hypothesize that ghrelin will increase dopamine release in the striatum and that this will, in turn, lead to an increase in the willingness to work for rewards. Moreover, the investigators expect that ghrelin-induced dopamine release will be associated with an elevated tracking of reward utility in the mesolimbic circuit during the IMT, which is known to be associated with response vigor. Collectively, the proposed project would provide a unique resource to test an important link between the gut and the brain in the regulation of appetitive behavior. If ghrelin were to enhance effort expenditure for rewards via dopamine signaling in humans, then restoring sensitivity to ghrelin might be the more promising therapeutic approach compared to antagonizing the ghrelin receptor.
The purpose of this study is to advance a non-pharmacologic suicide preventive intervention with wide dissemination potential as an innovative high-yield solution to reduce suicide rates. The investigators aim to achieve this with this study of Brain Emotion Circuitry Self-Monitoring and Regulation Therapy for Daily Rhythms (BE-SMART-DR), that provides self-directed strategies to regularize sleep and other DRs to reduce short-term suicide risk that can be used lifelong to potentially also reduce long-term suicide risk.
