The purpose of this study is to assess the efficacy of flexibly dosed JNJ-42847922 (20 milligram [mg] or 40 mg) compared to flexibly dosed quetiapine extended-release (XR) (150 mg or 300 mg) as adjunctive therapy to an antidepressant drug in delaying time to all-cause discontinuation of study drug over a 6-month treatment period, in participants with major depressive disorder (MDD) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).
This study will assess the efficacy of brief mindfulness practices on improving mental health in adults who are currently in treatment for mental health concerns. From online instructional videos, each participant will learn a thirty-second or three-minute mindfulness practice that is to be performed at least three times daily over two weeks.
The primary study objective is to observe/measure the circadian pattern of sleep, Cortisol and Melatonin in MDD subjects and Control subjects. We will also assess if controlled exposure to light in MDD subjects (post-partum females, non- post-partum females and males) will change these parameters using light glasses. In addition to the biological outcome measures (sleep, cortisol and melatonin) we will also monitor sleep and depressive symptoms in the research subjects for the duration of the protocol.
Depression is a common disorder, especially in old age, where it is associated with significant morbidity and mortality. This study will investigate whether there are features of individual patients with major depression that may predict positive treatment response. The study will invite 40 patients who have been diagnosed with major depressive disorder with onset after the age of 60 years to participate. Participants will be recruited from the Mental Health of Older Adults services at the South London and Maudsley NHS Mental Health Foundation Trust. Participants will receive usual treatment as set out in standard Care Pathways, used by the clinical care team. As part of the study, they will undergo a short battery of neuropsychological tests and a standard MRI brain imaging protocol. The neuropsychological tests and assessment of depression severity will be carried out twice (at Baseline and Week 12). Data will be analysed to investigate whether there are features specific to those patients who show a good response to antidepressant treatment after 12 weeks. Identification of such predictors may help to stratify treatment approaches in the future and lead to the early identification of individual patients who may require alternative treatment approaches to standard antidepressants.
Chronotherapy is a term that describes therapeutic alterations of sleep wake cycles. Different variations of sleep deprivation, set sleep wake schedules, and types of light therapy have demonstrated efficacy in rapidly treating depression, and suicidal thinking. This study seeks to explore the effect of two different chronotherapuetic protocols on acutely depressed and suicidal inpatients admitted to the Medical University of South Carolina
Objective: A traumatic brain injury (TBI) places individuals at high risk for developing posttraumatic stress disorder (PTSD). TBIs account for the onset of PTSD in approximately 700,000 Americans each year. Depression and post-concussive syndrome (PCS) are also common and often comorbid with PTSD. However, even in this group, there is a high-level of inter-individual response to traumatic brain injuries, suggesting that a better understanding of the mechanisms underlying this risk would be of great value in directing preventive interventions. The reasons for this heterogeneity are undoubtedly multi-factorial, and involve a complex interplay between genetic and environmental factors, that we may be able to understand through peripheral biomarkers and central examination of neuronal functioning. We suggest that DNA methylation may be a putative biomarker of psychiatric risk, as it reflects long-term changes in the function of the gene and may shape the recovery ability of the TBI patient through changes in cell function. In addition, differential proteomic response, including the function of the neuroendocrine system, likely relates to changes from epigenetic modification in both neurons and immune cells, which may contribute to the risk for the onset of PTSD as well as depression and PCS. We have previously shown that both PTSD and depression are associated with endocrine alterations, leading us to question if this biological change may underlie vulnerability for the onset of PTSD as well as depression and PCS following a TBI. In support of the idea of shared vulnerability, patients with a TBI also often display endocrine function alterations. In addition, sleep disturbance is common following TBI and is a core symptom of PTSD depression and PCS, suggesting that sleep may contribute to psychiatric and neurological recovery from a TBI. This line of research is essential, as current treatments to prevent or treat psychiatric risk following TBI are often ineffective, and even treatment of PCS is limited. This poor understanding results in our limited ability to reduce the risk for compromises in the health and well-being of patients who sustain a TBI. Study population: Participants with a moderate or mild TBI (n=100) will be followed for a period of one year. Design: This is a natural history study that will recruit patients within 30 days of a mild/moderate TBI, and will follow them over a one year period, with follow-up at 1, 3, 6 and 12 months following the TBI. Biological profiles including the concentration of inflammatory proteins and neuropeptides, and DNA methylation will be examined. An optional structural and functional magnetic resonance imaging (fMRI), and a hydrocortisone stimulation test will be used to evaluate the role of neuronal and neuroendocrine functioning following TBI. Outcome measures: The primary outcomes of interest are the biological changes that occur following TBI which are associated with the onset of psychiatric disorders of PTSD, and depression, as well as the onset of PCS. The secondary aim is to examine neuronal mechanisms that underlie the risks for these disorders through the use of fMRI. Additional aims will determine the role of psychological resilience traits in recovery and also how sleep relates to recovery and psychiatric risk.
This study is designed to take a first step toward testing the efficacy and acceptability of heart rate variability biofeedback (HRVB) as a means of ameliorating psychological distress in survivors of Primary Brain Tumour (PBT). HRVB is a biofeedback approach that provides clients with real time feedback about their heart rate variability (HRV) as a means of teaching them how to breathe in a specific, therapeutic manner. More specifically, this study has been designed to test several hypothesises. Each hypothesis is based on the prediction that, in a sample of psychologically distressed PBT survivors, a course of 8 HRVB sessions will demonstrate: - statistically significant reductions in levels of depression - statistically significant reductions in levels of anxiety - statistically significant increases in resting HRV - that reductions in anxiety and depression will be significantly, negatively correlated with increases in resting HRV - that the HRVB will be viewed as an acceptable intervention by the participants In addition to the hypothesises stated above, the study will also investigate in a discovery oriented manner if the HRVB intervention will have positive impacts on the participants: - levels of sleep impairment - levels of pain
To demonstrate the efficacy of multiple applications of Low Field Magnetic Stimulation (LFMS) as an antidepressant treatment in subjects with mood disorders.
This protocol, "Repetitive Transcranial Magnetic Stimulation (rTMS) for the Treatment of Major Depressive Disorder (MDD): A Functional Connectivity Magnetic Resonance Imaging (fcMRI) Study," is an open-label pilot treatment study. The purpose of the present protocol is to treat participants with a diagnosis of Major Depressive Disorder with 4 weeks of rTMS, performing fcMRI and EEG studies prior to and following treatment to determine if treatment response is related to changes in fcMRI and/or EEG results. The investigators hypothesize that patients who respond to treatment will display changes in functional connectivity patterns thought to be related to the occurrence of depressive symptoms.
This study will be conducted to determine the pharmacodynamics, cardiovascular and biochemical effects of succinylcholine when given during electroconvulsive therapy. (ECT). This is a single center, prospective, study in patients who will be receiving ECT as indicated and prescribed by their psychiatrist. The study will be performed twice on each patient, 48-72 hours apart during consecutively scheduled ECT procedures.
