Filter by:The presented project is an open and controlled single-center prospective exploratory study, evaluating the metabolic concentrations in the ventral striatum (VS), the Anterior cingulate cortex (ACC) and the prefrontal cortex (PFC) on the left and on the right of patients in remission of unipolar mood disorder and type II bipolar mood disorder compared to each other and to healthy subjects using NMR spectrometric measurements. We hypothesize that there is a significant difference between the mean glutamate concentrations in the ventral striatum (right and left) of the two groups of unipolar and bipolar type II patients. The average glutamate concentration would be higher for participants in the group of type II bipolar patients.
Depression is a common disorder that often takes a recurrent or chronic course. Recent research has indicated that such courses are associated with significant changes in brain functioning including changes in strength of functional connectivity between regions of the default mode network, a large-scale brain network involved in spontaneous thinking and rumination, and the ability to suppress this network. Training in mindfulness has been found to be an effective treatment for patients with recurrent and chronic courses of depression and there is evidence for beneficial effects on brain structure and functioning. However, it remains unclear whether and in how far the training may serve to reverse brain changes in recurrent and chronic courses of depression. The aim of this research is to test the effects of sustained training in mindfulness meditation on default mode network connectivity and suppression in patients suffering from recurrent or chronic depression. The investigators will invite currently depressed patients with a recurrent or chronic course of the disorder (N = 36) to take part in a 6-month mindfulness intervention and investigate changes in default-mode network connectivity and suppression over repeated assessments. Building on our previous research, the intervention will use a blended format that combines an online app offering psychoeducational materials and meditation guidance with brief individual therapy sessions delivered via videoconference. Eligible participants will be asked to complete questionnaires and take part in brain scans before the start of the treatment, 3 months after the start of the treatment and after the end of treatment.
The goal of this observational study is to determine the feasibility of using integrated Transcranial Doppler Ultrasonography or Near Infrared Spectroscopy to detect changes in cerebral autoregulation and neurovascular coupling in healthy, stroke, dementia, depression and delirium populations. We also aim to: - Determine the optimal stimulus for neurovascular coupling - To derive sample size estimates for a future study - To develop a multilevel, multivariate model that can be applied to future datasets
Estimation of vitamin B 6 levels in diagnosed major depressive disorder patients and their relation to the severity of the disease
Depression is a leading cause of disability worldwide, affecting up to 300 million people globally. Despite its high prevalence and debilitating effects, only one-third of patients newly diagnosed with depression initiate treatment. Electronic cognitive behavioural therapy (e-CBT) is an effective treatment for depression and is a feasible solution to make mental health care more accessible. Due to its online format, e-CBT can be combined with variable therapist engagement to address different care needs. Typically, a multi-professional care team determines which combination therapy is the most beneficial to the patient. However, this process can add to the costs of these programs. Artificial intelligence (AI) technology has been proposed to offset these costs. Therefore, this study aims to determine a cost-effective method to decrease depressive symptoms and increase treatment adherence to e-CBT. This will be done by comparing AI technology to a multi-professional care team when allocating the correct intensity of care for individuals diagnosed with depression. This study is a double-blinded randomized controlled trial recruiting individuals (n = 186) experiencing depression according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). The degree of care intensity a participant will receive will be randomly decided by either: (1) a machine learning algorithm (n = 93), or (2) an assessment made by a group of healthcare professionals (n = 93). Subsequently, participants will receive depression-specific e-CBT treatment through the secure online platform, OPTT. There will be three available intensities of therapist interaction: (1) e-CBT; (2) e-CBT with a 15-20-minute phone/video call; and (3) e-CBT with pharmacotherapy. This approach aims to accurately allocate care tailored to each patient's needs, allowing for more efficient use of resources.
This qualitative nested sub-study will aim to explore how chronic pain (as defined as pain lasting for more than 3 months) impacts older adults' depression and treatment in a brief psychological therapy of behavioral activation (BA)
The investigators are studying the feasibility, safety, and tolerability of administering accelerated repetitive Transcranial magnetic stimulation(a-rTMS) at frequencies other than standard 10 Hz for in-patient Subjects diagnosed with Major Depressive Disorder. Participants will be recruited from the Resnick Neuropsychiatric Hospital. This study will enroll 30 participants who will undergo up to three brain activity recordings, one MRI scan, one TMS procedure to determine the appropriate frequency and intensity for treatment, daily symptom assessments, and 25 TMS treatments. Participants will be asked to participate for up to 2 weeks.
This is a randomised, double-blind, placebo-controlled clinical trial in which patients with major depressive disorder will receive augmentation through minocycline (MCO), celecoxib (CXB) or placebo.
The goal of this clinical trial is to test SPL026 given via injection into a muscle in healthy volunteers.
Title: "Feasibility and acceptability study of "Mamá, te entiendo": an app-based intervention for reducing depressive symptoms in postpartum women" Funding: This work was funded by the Chilean National Agency of Research and Development (ANID Doctorado Nacional 2019 - 21190745). General objective: To assess the feasibility and acceptability of a guided 8-week cognitive-behavioral app-based intervention for Chilean postpartum women with depressive symptoms. Design: A small-scale parallel 2-arms trial will be conducted. Postpartum women with minor or major depression will be randomized to the app-based intervention or waitlist. The primary outcomes are feasibility and acceptability variables, mainly; recruitment and eligibility rates, intervention and study adherence, and participants' intervention satisfaction, use, and engagement. Semi-structured interviews with a sub-sample will provide more information about the participants' experience with the intervention. Women's depression diagnostic status will be assessed at pre-treatment, post-treatment, and 1-month follow-up. Other secondary outcomes will include participants' perceived social support, mother-infant bonding, and maternal satisfaction and self-efficacy.
