Efficacy of Electronic Cognitive Behavioral Therapy Application to Treat Major Depressive Disorder...
Major Depressive DisorderThe primary objective of this study is to evaluate the safety and efficacy of an electronic cognitive behavioral therapy application (eCBT Mood) compared to a control group consisting of a mood monitoring handheld computer application in the treatment of patients with mild to moderate major depressive disorder.
Early Intervention for Youth at Risk for Bipolar Disorder
Bipolar DisorderMajor Depressive DisorderChildren or teens with mood swings or depression who have a parent with bipolar disorder are at high risk for developing bipolar disorder themselves. This study will test a family-based therapy aimed at preventing or reducing the early symptoms of bipolar disorder in high-risk children (ages 9-17). In a randomized trial, the investigators will compare two kinds of family-based treatment (one more and one less intensive) on the course of early mood symptoms and social functioning among high-risk children followed for up to 4 years. The investigators will examine the effects of family treatment on measures of neural activation using functional magnetic resonance imaging.
Multimodal Assessment of Neurobiological Markers for Psychiatric Disorders
Major Depressive Disorder (MDD)Anxiety DisorderMAN-BIOPSY pursues the concrete research question whether novel biological and psycho-physiological clusters or categories can be defined to improve treatment and minimize side effects in psychiatry, based on a synopsis of physiological, behavioural, genetic and endocrinological parameters. One major aspect of our research approach is its focuses on the identification of dysfunctions in fundamental information processing mechanisms and neurocomputational mechanisms, and is not restricted to symptom-oriented tasks. The main objectives of MAN-BIOPSY are therefore to identify biological and psycho-physiological parameters for major depressive disorders and anxiety disorders, and to identify predictive markers for treatment response and type/severity of side effects for these disorders.
Efficacy and Safety of Escitalopram for Prevention of Depression Induced by Peg-Interferon in Hepatitis...
Major Depressive DisorderHepatitis C1 moreThe purpose of this study is to determine whether the use of an antidepressant (escitalopram) can prevent depressive episodes that appear during the treatment with peg-interferon and ribavirin in patients with chronic hepatitis C.
Study of Rapastinel as Monotherapy in Major Depressive Disorder (MDD)
Depressive DisorderMajorThe study will evaluate the efficacy, safety, and tolerability of 450 milligrams (mg) of Rapastinel, compared to 10 mg of Vortixetine and placebo in participants with major depressive disorder (MDD).
Pathophysiology of Neurodegeneration in Late-life Depression (AV45+THK)
Major Depressive DisorderLate-life depression has been frequently associated with cognitive impairment. Several meta-analyses consistently suggested that a history of depression approximately doubles an individual's risk for developing dementia later in life. Neurodegeneration may play an important component in late-life depression. The pathophysiology behind the link between late-life depression and the subsequent development of dementia largely remains unclear, and should be heterogeneous. This highlights the need to identify specific neurodegenerative pathways involved in late-life depression, which will facilitate research on mechanisms and new treatments in the future. The recently published the National Institute on Aging and the Alzheimer Association (NIA-AA) criteria might provide new insights and frameworks to explore the patterns of neurodegenerative process in elderly depressed patients and to categorize them into different biomarker-based groups. In the present project, the investigators will recruit 40 patients with lifetime major depressive disorder, and 20 non-depressed cognitively normal comparison subjects. Alzheimer's disease pathology (A) was determined by measuring Aβ deposition by F-18 AV-45 PET, and neurodegeneration (N) was established by measuring hippocampal volume using MRI. Individuals were categorised as A-N-, A+N-, A+N+, or suspected non-Alzheimer's disease pathophysiology (A-N+, SNAP). All subjects will further undergo F-18-THK-5351 image study to detect underlying tau pathology. By doing this, the investigators will elucidate the neurodegenerative pathophysiology behind the link between depressive disorder and the subsequent development of dementia.
Treatment for Cognitive Impairment in Depression
Major Depressive DisorderThe proposed study seeks to investigate the effects of modafinil on cognitive function in depression, which holds promise for better treating cognitive impairment in depression, as well as better understand cognitive dysfunction in MDD from a neural rather than diagnostic point of view to better classify and treat these disabling symptoms.
Canadian Biomarker Integration Network for Depression (CAN-BIND) - Validation Study
Major Depressive DisorderThis is a validation study that will replicate a completed study designed to assess biomarkers of treatment response to standard antidepressant treatment. The goal of this study is to integrate clinical, imaging, EEG, and molecular data across 8 sites to predict treatment outcome for patients experiencing a major depressive episode (MDE).
The Effects of Vilazodone on Glutamate in the Anterior Cingulate Cortex in Anxious Unipolar Depressives...
Major Depressive DisorderAnxiety1 moreThe purpose of this study is to determine whether vilazodone is more effective than citalopram for the treatment of anxious depression. We will use neuroimaging to see whether there are changes in the brains of patients receiving the drug vilazodone that are different from those of citalopram. These changes may show that vilazodone affects the brain differently than most other kinds of standard antidepressant medications.
Cognitive-behavioral Therapy vs. Light Therapy for Preventing SAD Recurrence
Seasonal Affective Disorder (SAD)Winter Depression3 moreMajor depression is a highly prevalent, chronic, and debilitating mental health problem with significant social cost that poses a tremendous economic burden. Winter seasonal affective disorder (SAD) is a subtype of recurrent major depression involving substantial depressive symptoms that adversely affect the family and workplace for about 5 months of each year during most years, beginning in young adulthood. This clinical trial is relevant to this public health challenge in seeking to develop and test a time-limited (i.e., acute treatment completed in a discrete period vs. daily treatment every fall/winter indefinitely), palatable cognitive-behavioral treatment with effects that endure beyond the cessation of acute treatment to prevent the annual recurrence of depression in SAD. Aim (1) To compare the long-term efficacy of cognitive-behavioral therapy (CBT) and light therapy on depression recurrence status, symptom severity, and remission status during the next winter season (i.e., the next wholly new winter season after the initial winter of treatment completion), which we argue to be the most important time point for evaluating clinical outcomes following SAD intervention. Hypothesis: CBT will be associated with a smaller proportion of depression recurrences, less severe symptoms, and a higher proportion of remissions than light therapy in the next winter. The study is designed to detect a clinically important difference between CBT and light therapy in depressive episode recurrences during the next winter, the primary endpoint, in an intent-to-treat analysis. Aim (2) To compare the efficacy of CBT and light therapy on symptom severity and remission status at post-treatment (treatment endpoint). Hypothesis: CBT and light therapy will not differ significantly on post-treatment outcomes.
